Valhalla's Things: A Corset or Two

Posted on January 7, 2024
Tags: madeof:atoms, craft:sewing, period:victorian, FreeSoftWear
a black coutil midbust corset, from a 3/4 front view, showing the busk closure, a waist tape and external boning channels made of the same twill tape and placed about 1-2 cm from each other at waist level. CW for body size change mentions I needed a corset, badly. Years ago I had a chance to have my measurements taken by a former professional corset maker and then a lesson in how to draft an underbust corset, and that lead to me learning how nice wearing a well-fitted corset feels. Later I tried to extend that pattern up for a midbust corset, with success. And then my body changed suddenly, and I was no longer able to wear either of those, and after a while I started missing them. Since my body was still changing (if no longer drastically so), and I didn t want to use expensive materials for something that had a risk of not fitting after too little time, I decided to start by making myself a summer lightweight corset in aida cloth and plastic boning (for which I had already bought materials). It fitted, but not as well as the first two ones, and I ve worn it quite a bit. I still wanted back the feeling of wearing a comfy, heavy contraption of coutil and steel, however. After a lot of procrastination I redrafted a new pattern, scrapped everything, tried again, had my measurements taken by a dressmaker [#dressmaker], put them in the draft, cut a first mock-up in cheap cotton, fixed the position of a seam, did a second mock-up in denim [#jeans] from an old pair of jeans, and then cut into the cheap herringbone coutil I was planning to use. And that s when I went to see which one of the busks in my stash would work, and realized that I had used a wrong vertical measurement and the front of the corset was way too long for a midbust corset. a corset busk basted to a mock-up with scraps of fabric between each stud / loop. Luckily I also had a few longer busks, I basted one to the denim mock up and tried to wear it for a few hours, to see if it was too long to be comfortable. It was just a bit, on the bottom, which could be easily fixed with the Power Tools1. Except, the more I looked at it the more doing this felt wrong: what I needed most was a midbust corset, not an overbust one, which is what this was starting to be. I could have trimmed it down, but I knew that I also wanted this corset to be a wearable mockup for the pattern, to refine it and have it available for more corsets. And I still had more than half of the cheap coutil I was using, so I decided to redo the pattern and cut new panels. And this is where the or two comes in: I m not going to waste the overbust panels: I had been wanting to learn some techniques to make corsets with a fashion fabric layer, rather than just a single layer of coutil, and this looks like an excellent opportunity for that, together with a piece of purple silk that I know I have in the stash. This will happen later, however, first I m giving priority to the underbust. Anyway, a second set of panels was cut, all the seam lines marked with tailor tacks, and I started sewing by inserting the busk. And then realized that the pre-made boning channel tape I had was too narrow for the 10 mm spiral steel I had plenty of. And that the 25 mm twill tape was also too narrow for a double boning channel. On the other hand, the 18 mm twill tape I had used for the waist tape was good for a single channel, so I decided to put a single bone on each seam, and then add another piece of boning in the middle of each panel. Since I m making external channels, making them in self fabric would have probably looked better, but I no longer had enough fabric, because of the cutting mishap, and anyway this is going to be a strictly underwear only corset, so it s not a big deal. Once the boning channel situation was taken care of, everything else proceeded quite smoothly and I was able to finish the corset during the Christmas break, enlisting again my SO to take care of the flat steel boning while I cut the spiral steels myself with wire cutters. The same corset straight from the front: the left side is a few mm longer than the right side I could have been a bit more precise with the binding, as it doesn t align precisely at the front edge, but then again, it s underwear, nobody other than me and everybody who reads this post is going to see it and I was in a hurry to see it finished. I will be more careful with the next one. The same corset from the back, showing cross lacing with bunny ears at the waist and a lacing gap of about 8 cm. I also think that I haven t been careful enough when pressing the seams and applying the tape, and I ve lost about a cm of width per part, so I m using a lacing gap that is a bit wider than I planned for, but that may change as the corset gets worn, and is still within tolerance. Also, on the morning after I had finished the corset I woke up and realized that I had forgotten to add garter tabs at the bottom edge. I don t know whether I will ever use them, but I wanted the option, so maybe I ll try to add them later on, especially if I can do it without undoing the binding. The next step would have been flossing, which I proceeded to postpone until I ve worn the corset for a while: not because there is any reason for it, but because I still don t know how I want to do it :) What was left was finishing and uploading the pattern and instructions, that are now on my sewing pattern website as #FreeSoftWear, and finally I could post this on the blog.

  1. i.e. by asking my SO to cut and sand it, because I m lazy and I hate doing that part :D

Shirish Agarwal: Odisha Train Crash and Coverup, Demonetization 2.0 & NHFS-6 Survey

Just a few days back we came to know about the horrific Train Crash that happened in Odisha (Orissa). There are some things that are known and somethings that can be inferred by observance. Sadly, it seems the incident is going to be covered up  . Some of the facts that have not been contested in the public domain are that there were three lines. One loop line on which the Goods Train was standing and there was an up and a down line. So three lines were there. Apparently, the signalling system and the inter-locking system had issues as highlighted by an official about a month back. That letter, thankfully is in the public domain and I have downloaded it as well. It s a letter that goes to 4 pages. The RW is incensed that the letter got leaked and is in public domain. They are blaming everyone and espousing conspiracy theories rather than taking the minister to task. Incidentally, the Minister has three ministries that he currently holds. Ministry of Communication, Ministry of Electronics and Information Technology (MEIT), and Railways Ministry. Each Ministry in itself is important and has revenues of more than 6 lakh crore rupees. How he is able to do justice to all the three ministries is beyond me  The other thing is funds both for safety and relaying of tracks has been either not sanctioned or unutilized. In fact, CAG and the Railway Brass had shared how derailments have increased and unfulfilled vacancies but they were given no importance  In fact, not talking about safety in the recently held Chintan Shivir (brainstorming session) tells you how much the Govt. is serious about safety. In fact, most of the programme was on high speed rail which is a white elephant. I have shared a whitepaper done by RW in the U.S. that tells how high-speed rail doesn t make economic sense. And that is an economy that is 20 times + the Indian Economy. Even the Chinese are stopping with HSR as it doesn t make economic sense. Incidentally, Air Fares again went up 200% yesterday. Somebody shared in the region of 20k + for an Air ticket from their place to Bangalore  Coming back to the story itself. the Goods Train was on the loopline. Some say it was a little bit on the outer, some say otherwise, but it is established that it was on the loopline. This is standard behavior on and around Railway Stations around the world. Whether it was in the Inner or Outer doesn t make much of a difference with what happened next. The first train that collided with the goods train was the 12864 (SMVB-HWH) Yashwantpur Howrah Express and got derailed on to the next track where from the opposite direction 12841 (Shalimar- Bangalore) Coramandel Express was coming. Now they have said that around 300 people have died and that seems to be part of the cover-up. Both the trains are long trains, having between 23 odd coaches each. Even if you have reserved tickets you have 80 odd people in a coach and usually in most of these trains, it is at least double of that. Lot of money goes to TC and then above (Corruption). The Railway fares have gone up enormously but that s a question for perhaps another time  . So at the very least, we could be looking at more than 1000 people having died. The numbers are being under-reported so that nobody has to take responsibility. The Railways itself has told that it is unable to identify 80% of the people who have died. This means that 80% were unreserved ticket holders or a majority of them. There have been disturbing images as how bodies have been flung over on tractors and whatnot to be either buried or cremated without a thought. We are in peak summer season so bodies will start to rot within 24-48 hours  No arrangements made to cool the bodies and take some information and identifying marks or whatever. The whole thing being done in a very callous manner, not giving dignity to even those who have died for no fault of their own. The dissent note also tells that a cover-up is also in the picture. Apparently, India doesn t have nor does it feel to have a need for something like the NTSB that the U.S. used when it hauled both the plane manufacturer (Boeing) and the FAA when the 737 Max went down due to improper data collection and sharing of data with pilots. And with no accountability being fixed to Minister or any of the senior staff, a small junior staff person may be fired. Perhaps the same official that actually told them about the signal failures almost 3 months back  There were and are also some reports that some jugaadu /temporary fixes were applied to signalling and inter-locking just before this incident happened. I do not know nor confirm one way or the other if the above happened. I can however point out that if such a thing happened, then usually a traffic block is announced and all traffic on those lines are stopped. This has been the thing I know for decades. Traveling between Mumbai and Pune multiple times over the years am aware about traffic block. If some repair work was going on and it wasn t able to complete the work within the time-frame then that may well have contributed to the accident. There is also a bit muddying of the waters where it is being said that one of the trains was 4 hours late, which one is conflicting stories. On top of the whole thing, they have put the case to be investigated by CBI and hinting at sabotage. They also tried to paint a religious structure as mosque, later turned out to be a temple. The RW says done by Muslims as it was Friday not taking into account as shared before that most Railway maintenance works are usually done between Friday Monday. This is a practice followed not just in India but world over. There has been also move over a decade to remove wooden sleepers and have concrete sleepers. Unlike the wooden ones they do not expand and contract as much and their life is much more longer than the wooden ones. Funds had been marked (although lower than last few years) but not yet spent. As we know in case of any accident, it is when all the holes in cheese line up it happens. Fukushima is a great example of that, no sea wall even though Japan is no stranger to Tsunamis. External power at the same level as the plant. (10 meters above sea-level), no training for cascading failures scenarios which is what happened. The Days mini-series shares some but not all the faults that happened at Fukushima and the Govt. response to it. There is a difference though, the Japanese Prime Minister resigned on moral grounds. Here, nor the PM, nor the Minister would be resigning on moral grounds or otherwise :(. Zero accountability and that was partly a natural disaster, here it s man-made. In fact, both the Minister and the Prime Minister arrived with their entourages, did a PR blitzkrieg showing how concerned they are. Within 50 hours, the lines were cleared. The part-time Railway Minister shared that he knows the root cause and then few hours later has given the case to CBI. All are saying, wait for the inquiry report. To date, none of the accidents even in this Govt. has produced an investigation report. And even if it did, I am sure it will whitewash as it did in case of Adani as I had shared before in the previous blog post. Incidentally, it is reported that Adani paid off some of its debt, but when questioned as to where they got the money, complete silence on that part :(. As can be seen cover-up after cover-up  FWIW, the Coramandel Express is known as the Migrant train so has a huge number of passengers, the other one which was collided with is known as sick train as huge number of cancer patients use it to travel to Chennai and come back

Demonetization 2.0 Few days back, India announced demonetization 2.0. Surprised, don t be. Apparently, INR 2k/- is being used for corruption and Mr. Modi is unhappy about it. He actually didn t like the INR 2k/- note but was told that it was needed, who told him we are unaware to date. At that time the RBI Governor was Mr. Urjit Patel who didn t say about INR 2k/- he had said that INR 1k/- note redesigned would come in the market. That has yet to happen. What has happened is that just like INR 500/- and INR 1k/- note is concerned, RBI will no longer honor the INR 2k/- note. Obviously, this has made our neighbors angry, namely Nepal, Sri Lanka, Bhutan etc. who do some trading with us. 2 Deccan herald columns share the limelight on it. Apparently, India wants to be the world s currency reserve but doesn t want to play by the rules for everyone else. It was pointed out that both the U.S. and Singapore had retired their currencies but they will honor that promise even today. The Singapore example being a bit closer (as it s in Asia) is perhaps a bit more relevant than the U.S. one. Singapore retired the SGD $10,000 as of 2014 but even in 2022, it remains as legal tender. They also retired the SGD $1,000 in 2020 but still remains legal tender.

So let s have a fictitious example to illustrate what is meant by what Singapore has done. Let s say I go to Singapore, rent a flat, and find a $1000 note in that house somewhere. Both practically and theoretically, I could go down to any of the banks, get the amount transferred to my wallet, bank account etc. and nobody will question. Because they have promised the same. Interestingly, the Singapore Dollar has been pretty resilient against the USD for quite a number of years vis-a-vis other Asian currencies. Most of the INR 2k/- notes were also found and exchanged in Gujarat in just a few days (The PM and HM s state.). I am sure you are looking into the mental gymnastics that the RW indulge in :(. What is sadder that most of the people who try to defend can t make sense one way or the other and start to name-call and get personal as they have nothing else

Disability questions dropped in NHFS-6 Just came to know today that in the upcoming National Family Health Survey-6 disability questions are being dropped. Why is this important. To put it simply, if you don t have numbers, you won t and can t make policies for them. India is one of the worst countries to live if you are disabled. The easiest way to share to draw attention is most Railway platforms are not at level with people. Just as Mick Lynch shares in the UK, the same is pretty much true for India too. Meanwhile in Europe, they do make an effort to be level so even disabled people have some dignity. If your public transport is sorted, then people would want much more and you will be obligated to provide for them as they are citizens. Here, we have had many reports of women being sexually molested when being transferred from platform to coach irrespective of their age or whatnot  The main takeaway is if you do not have their voice, you won t make policies for them. They won t go away but you will make life hell for them. One thing to keep in mind that most people assume that most people are disabled from birth. This may or may not be true. For e.g. in the above triple Railways accidents, there are bound to be disabled people or newly disabled people who were healthy before the accident. The most common accident is road accidents, some involving pedestrians and vehicles or both, the easiest is Ministry of Road Transport data that says 4,00,000 people sustained injuries in 2021 alone in road mishaps. And this is in a country where even accidents are highly under-reported, for more than one reason. The biggest reason especially in 2 and 4 wheeler is the increased premium they would have to pay if in an accident, so they usually compromise with the other and pay off the Traffic Inspector. Sadly, I haven t read a new book, although there are a few books I m looking forward to have. People living in India and neighbors please be careful as more heat waves are expected. Till later.

Ritesh Raj Sarraf: Plant Territorial Behavior

This blog post is about my observations of some of the plants in my home garden. While still a n00b on the subject, these notes are my observations and experiences over days, weeks and months. Thankfully, with the capability to take frequent pictures, it has been easy to do an assessment and generate a report of some of these amazing behaviors of plants, in an easy timeline order; all thanks to the EXIF data embedded. This has very helpfully allowed me to record my, otherwise minor observations, into great detail; and make some sense out of it by correlating the data over time. It is an emotional experience. You see, plants are amazing. When I sow a sapling, water it, feed it, watch it grow, prune it, medicate it, and what not; I build up affection towards it. Though, at the same time, to me it is a strict relationship, not too attached; as in it doesn t hurt to uproot a plant if there is a good reason. But still, I find some sort of association to it. With plants around, it feels I have a lot of lives around me. All prospering, communicating, sharing. And communicate they do. What is needed is just the right language to observe and absorb their signals and decipher what they are trying to say.

Devastation How in this world, when you are caring for your plants, can it transform:

From This
Healthy Mulberry Plant

Healthy Bael Plant

To This
Dead Mulberry Plant
Dead Mulberry Plant
Very Sick Bael Plant
Very Sick Bael Plant
With emotions involved, this can be an unpleasant experience. Bael is a dear plant to me. The plant as a whole has religious values (Shiva). As well, its fruits have lots of health benefits, especially for the intestines. Its leaves have a lot of medicinal properties. When I planted the Bael, there were a lot of emotions that went along. On the other hand, the Mulberry is something I put in with a lot of enthusiasm. Mulberries are now rare to find, especially in urban locations. For one, they have a very short shelf life; But more than that, the way lifestyles are heading towards, I was always worried if my children would ever have a day to see and taste these fruits. The mulberry that I planted, yielded twice; once very soon when I had planted and second, before it died. Infact, it died while during its second yield phase. It was quite saddening to see that happen. It made me wonder why it happened. I had been caring for the plants fairly well. Watering them timely, feeding them the right amount of nutrients. They were getting a good amount of sun. But still their health was deteriorating. And then the demise of the Mulberry. Many thoughts hit my mind. I consulted the claimed experts in the domain, the maali, the gardener. I got a very vague answer; there must be termites in the soil. It didn t make much sense to me. I mean if there are termites they d hit day one. They won t sleep for months and just wake up one fine day and start attacking the roots of particular plants; not all. I wasn t convinced with the termite theory; But still, give the expert the blind hand, I went with his word. When my mulberry was dead, I dug its roots. Looking for proof, to see if there were any termites, I uprooted it. But I couldn t find any trace of termites. And the plant next to it was perfectly healthy and blossoming. So I was convinced that it wasn t the termite but something else. But else what ? I still didn t have an answer to that.

Thinking The Corona pandemic had embraced and there was a lot to worry, and worry not any, if you change the perspective. With plants around in my home, and our close engagement with them, and the helplessness that I felt after seeking help from the experts, it was time again; to build up some knowledge on the subject. But how ? How do you go about a subject you have not much clue about ? A subject which has always been around in the surrounding but very seldom have I dedicated focused thought to it. To be honest, the initial thought of diving on the subject made me clueless. I had no idea where to begin with. But, so, as has been my past history, I chose to take it as a curiosity. I gathered some books, skimmed through a couple of pages. Majority of the books I got hold of were about DIYs and How to do Home Gardening types. It was a decent introduction to a novice but my topic of curiosity was different. Thankfully, with the Internet, and YouTube in particular, a lot of good stuff is available as documentary videos. While going through some, I came across a video which mentioned about carnivore plants. Like, for example, this one.
Carnivore Plant
Carnivore Plant
This got me thinking that there could be a possibility of something similar, that did the fate to my Mulberry plant. But who did it ? And how to dive further on this suspicion ? And most of all, if that thought of possibility was actually the reality. Or was I just hitting in the dark ?

Beginning To put some perspective, here s how it started. When we moved into our home, the gardener put in a couple of plants stock, as part of the property handover. Now, I don t exactly recollect the name of the plants that came in stock, neither English nor Hindi; But at my neighbor s place, the plant is still there. Here are some of the pictures of this beauty. But don t just go by the looks as looks can be deceiving

We hadn t put any serious thought about the plants we were offered by the gardener. After all, we never had ever thought of any mishap either.

Plants we planted Apart from what was offered by the builder/gardener as part of the property handover, in over the next 6 months of we moving in, I planted 3 tree type plants.
  1. Mulberry
  2. Bael
  3. Rudraksha
The Mulberry, as I have described so far, died a tragic death. Bael, on the other hand, fought hard. But very little did we know that the plant was struggling the fight. Our impression was that we must have been given a bad breed of the plant. Or maybe the termite theory had some truth. For the Rudraksha plant, the growth was slow. This was the very first time I had seen a Rudraksha plant, so I had no clue of what its growth rate could be, and what to expect out of it. I wasn t sure if the local climate suited the plant. A quick search showed no objections to the plant in the local climate, but that was it. So my theory has been to put in the plant, and observe. Here s what my Rudraksha plant looked like during the initial days/weeks of its settlement
Rudraksha Plant
Rudraksha Plant

The Hint Days passed and so on. Not much had progressed in gathering information. The plant s health was usual; deteriorating at a slow pace. On day, thinking of the documentaries I had been watching, it hit my mind about the plant behavior.
  • Plants can be Carnivores.
  • Plants can be Aggressive.
  • Plants can be Invaders.
  • Plants can be Territorial.
There are many plants where their aggression can be witnessed with bare human eyes. Like creepers. Some of them are good at spreading tentacles, grabbing onto other plants' stems and branches and spread above it. This was my hint from the documentaries. That s one of the many ways plants set their dominance. That is what hit my mind that if plants are aggressive on the out, underneath the soil, they should be having similar behavior. I mean, what we see as humans is just a part of the actual plant. More than half of the actual plant is usually underneath the soil, in most plants. So there s a high chance to get more information out, if you dig the soil and look the roots.

The Digging As I mentioned earlier, I do establish bindings, emotions and attachments. But not much usually comes in the way to curiosity. To dig further on the theory that the problem was elsewhere, with within the plants ecosystem, we needed to pick on another subject - the plant. And the plant we chose was the plant which was planted in the initial offering to us, when we moved into our home. It was the same plant breed which was neighboring all our newly planted trees: Rudraksha, Mulberry and Bael. If you look closely into the pictures above of these plants, you ll notice the stem of another plant, the Territorial Dominator, is close-by to these 3 plants. That s because the gardener put in a good number of them to get his action item complete. So we chose to dig and uproot one of those plant to start with. Now, while they may look gentle on the outside, with nice red colored tiny flowers, these plants were giants underneath. Their roots were huge. It took some sweat shredding to single-handedly remove them.

The above ones are pictures of the same Bael plant, which had struggled to live, for almost 14 months. Back then, this plant was starved of its resources. It was dying a slow death out of starvation. After we uprooted the other dominant species, the Bael has recovered and has regained its charm. In the pictures above of the Bael plant, you can clearly mark out the difference in its stem. The dark colored one is from its months of struggle, while the bright green is from now where it is well nourished and regained its health.

Mulberry As for the Mulberry, I couldn t save it. But I later managed to get another one. But it turns out I didn t take good, full length pictures of the new mulberry when I planted. The only picture I have is this:
Second Mulberry Plant
Second Mulberry Plant
I recollect when I brought it home, it was around 1 - 1.5 feet in length. This is where I have it today: Majestically standing, 12 feet and counting
Second Mulberry Plant 7 feet tall

Rudraksha Then:

And now: I feel quite happy about

All these plants are on the very same soil with the very same care taker. What has changed is my experience and learning.

Plant Co-Existence Plant co-existence is a difficult topic. My knowledge on plants is very limited in general, and co-existence is something tricky, unexplored, at times invisible (when underneath the soil). So it is a difficult topic. So far, what I ve learnt is purely observations, experiences and hints from the documentaries. There surely are many many plants that co-exist very well. A good example is my Bael plant itself, which is healthily co-sharing its space with 2 other Croton plants. Same goes for the Rudraksha, which has a close-by neighbor in an Adenium and an Allamanda. The plant world is mesmerizing. How they behave, communicate and many many more signs. There s so much to observe, learn, explore and document. I hope to have more such observations and experiences to share

Shirish Agarwal: Population, Immigration, Vaccines and Mass-Surveilance.

The Population Issue and its many facets Another couple of weeks passed. A Lot of things happening, lots of anger and depression in folks due to handling in pandemic, but instead of blaming they are willing to blame everybody else including the population. Many of them want forced sterilization like what Sanjay Gandhi did during the Emergency (1975). I had to share So Long, My son . A very moving tale of two families of what happened to them during the one-child policy in China. I was so moved by it and couldn t believe that the Chinese censors allowed it to be produced, shot, edited, and then shared worldwide. It also won a couple of awards at the 69th Berlin Film Festival, silver bear for the best actor and the actress in that category. But more than the award, the theme, and the concept as well as the length of the movie which was astonishing. Over a 3 hr. something it paints a moving picture of love, loss, shame, relief, anger, and asking for forgiveness. All of which can be identified by any rational person with feelings worldwide.

Girl child What was also interesting though was what it couldn t or wasn t able to talk about and that is the Chinese leftover men. In fact, a similar situation exists here in India, only it has been suppressed. This has been more pronounced more in Asia than in other places. One big thing in this is human trafficking and mostly women trafficking. For the Chinese male, that was happening on a large scale from all neighboring countries including India. This has been shared in media and everybody knows about it and yet people are silent. But this is not limited to just the Chinese, even Indians have been doing it. Even yesteryear actress Rupa Ganguly was caught red-handed but then later let off after formal questioning as she is from the ruling party. So much for justice. What is and has been surprising at least for me is Rwanda which is in the top 10 of some of the best places in equal gender. It, along with other African countries have also been in news for putting quite a significant amount of percentage of GDP into public healthcare (between 20-10%), but that is a story for a bit later. People forget or want to forget that it was in Satara, a city in my own state where 220 girls changed their name from nakusha or unwanted to something else and that had become a piece of global news. One would think that after so many years, things would have changed, the only change that has happened is that now we have two ministries, The Ministry of Women and Child Development (MoWCD) and The Ministry of Health and Welfare (MoHFW). Sadly, in both cases, the ministries have been found wanting, Whether it was the high-profile Hathras case or even the routine cries of help which given by women on the twitter helpline. Sadly, neither of these ministries talks about POSH guidelines which came up after the 2012 gangrape case. For both these ministries, it should have been a pinned tweet. There is also the 1994 PCPNDT Act which although made in 1994, actually functioned in 2006, although what happens underground even today nobody knows  . On the global stage, about a decade ago, Stephen J. Dubner and Steven Levitt argued in their book Freakonomics how legalized abortion both made the coming population explosion as well as expected crime rates to be reduced. There was a huge pushback on the same from the conservatives and has become a matter of debate, perhaps something that the Conservatives wanted. Interestingly, it hasn t made them go back but go forward as can be seen from the Freakonomics site.

Climate Change Another topic that came up for discussion was repeatedly climate change, but when I share Shell s own 1998 Confidential report titled Greenhouse effect all become strangely silent. The silence here is of two parts, there probably is a large swathe of Indians who haven t read the report and there may be a minority who have read it and know what already has been shared with U.S. Congress. The Conservative s argument has been for it is jobs and a weak we need to research more . There was a partial debunk of it on the TBD podcast by Matt Farell and his brother Sean Farell as to how quickly the energy companies are taking to the coming change.

Health Budget Before going to Covid stories. I first wanted to talk about Health Budgets. From the last 7 years the Center s allocation for health has been between 0.34 to 0.8% per year. That amount barely covers the salaries to the staff, let alone any money for equipment or anything else. And here by allocation I mean, what is actually spent, not the one that is shared by GOI as part of budget proposal. In fact, an article on Wire gives a good breakdown of the numbers. Even those who are on the path of free markets describe India s health business model as a flawed one. See the Bloomberg Quint story on that. Now let me come to Rwanda. Why did I chose Rwanda, I could have chosen South Africa where I went for Debconf 2016, I chose because Rwanda s story is that much more inspiring. In many ways much more inspiring than that South Africa in many ways. Here is a country which for decades had one war or the other, culminating into the Rwanda Civil War which ended in 1994. And coincidentally, they gained independence on a similar timeline as South Africa ending Apartheid in 1994. What does the country do, when it gains its independence, it first puts most of its resources in the healthcare sector. The first few years at 20% of GDP, later than at 10% of GDP till everybody has universal medical coverage. Coming back to the Bloomberg article I shared, the story does not go into the depth of beyond-expiry date medicines, spurious medicines and whatnot. Sadly, most media in India does not cover the deaths happening in rural areas and this I am talking about normal times. Today what is happening in rural areas is just pure madness. For last couple of days have been talking with people who are and have been covering rural areas. In many of those communities, there is vaccine hesitancy and why, because there have been whatsapp forwards sharing that if you go to a hospital you will die and your kidney or some other part of the body will be taken by the doctor. This does two things, it scares people into not going and getting vaccinated, at the same time they are prejudiced against science. This is politics of the lowest kind. And they do it so that they will be forced to go to temples or babas and what not and ask for solutions. And whether they work or not is immaterial, they get fixed and property and money is seized. Sadly, there are not many Indian movies of North which have tried to show it except for oh my god but even here it doesn t go the distance. A much more honest approach was done in Trance . I have never understood how the South Indian movies are able to do a more honest job of story-telling than what is done in Bollywood even though they do in 1/10th the budget that is needed in Bollywood. Although, have to say with OTT, some baggage has been shed but with the whole film certification rearing its ugly head through MEITY orders, it seems two steps backward instead of forward. The idea being simply to infantilize the citizens even more. That is a whole different ball-game which probably will require its own space.

Vaccine issues One good news though is that Vaccination has started. But it has been a long story full of greed by none other than GOI (Government of India) or the ruling party BJP. Where should I start with. I probably should start with this excellent article done by Priyanka Pulla. It is interesting and fascinating to know how vaccines are made, at least one way which she shared. She also shared about the Cutter Incident which happened in the late 50 s. The response was on expected lines, character assassination of her and the newspaper they published but could not critique any of the points made by her. Not a single point that she didn t think about x or y. Interestingly enough, in January 2021 Bharati Biotech was supposed to be share phase 3 trial data but hasn t been put up in public domain till May 2021. In fact, there have been a few threads raised by both well-meaning Indians as well as others globally especially on twitter to which GOI/ICMR (Indian Council of Medical Research) is silent. Another interesting point to note is that Russia did say in its press release that it is possible that their vaccine may not be standard (read inactivation on their vaccines and another way is possible but would take time, again Brazil has objected, but India hasn t till date.) What also has been interesting is the homegrown B.1.617 lineage or known as double mutant . This was first discovered from my own state, Maharashtra and then transported around the world. There is also B.1.618 which was found in West Bengal and is same or supposed to be similar to the one found in South Africa. This one is known as Triple mutant . About B.1.618 we don t know much other than knowing that it is much more easily transferable, much more infectious. Most countries have banned flights from India and I cannot fault them anyway. Hell, when even our diplomats do not care for procedures to be followed during the pandemic then how a common man is supposed to do. Of course, now for next month, Mr. Modi was supposed to go and now will not attend the G7 meeting. Whether, it is because he would have to face the press (the only Prime Minister and the only Indian Prime Minister who never has faced free press.) or because the Indian delegation has been disinvited, we would never know.

A good article which shares lots of lows with how things have been done in India has been an article by Arundhati Roy. And while the article in itself is excellent and shares a bit of the bitter truth but is still incomplete as so much has been happening. The problem is that the issue manifests in so many ways, it is difficult to hold on. As Arundhati shared, should we just look at figures and numbers and hold on, or should we look at individual ones, for e.g. the one shared in Outlook India. Or the one shared by Dr. Dipshika Ghosh who works in Covid ICU in some hospital
Dr. Dipika Ghosh sharing an incident in Covid Ward

Interestingly as well, while in the vaccine issue, Brazil Anvisa doesn t know what they are doing or the regulator just isn t knowledgeable etc. (statements by various people in GOI, when it comes to testing kits, the same is an approver.)

ICMR/DGCI approving internationally validated kits, Press release.

Twitter In the midst of all this, one thing that many people have forgotten and seem to have forgotten that Twitter and other tools are used by only the elite. The reason why the whole thing has become serious now than in the first phase is because the elite of India have also fallen sick and dying which was not the case so much in the first phase. The population on Twitter is estimated to be around 30-34 million and people who are everyday around 20 odd million or so, which is what 2% of the Indian population which is estimated to be around 1.34 billion. The other 98% don t even know that there is something like twitter on which you can ask help. Twitter itself is exclusionary in many ways, with both the emoticons, the language and all sorts of things. There is a small subset who does use Twitter in regional languages, but they are too small to write anything about. The main language is English which does become a hindrance to lot of people.

Censorship Censorship of Indians critical of Govt. mishandling has been non-stop. Even U.S. which usually doesn t interfere into India s internal politics was forced to make an exception. But of course, this has been on deaf ears. There is and was a good thread on Twitter by Gaurav Sabnis, a friend, fellow Puneite now settled in U.S. as a professor.
Gaurav on Trump-Biden on vaccination of their own citizens
Now just to surmise what has been happened in India and what has been happening in most of the countries around the world. Most of the countries have done centralization purchasing of the vaccine and then is distributed by the States, this is what we understand as co-operative federalism. While last year, GOI took a lot of money under the shady PM Cares fund for vaccine purchase, donations from well-meaning Indians as well as Industries and trade bodies. Then later, GOI said it would leave the states hanging and it is they who would have to buy vaccines from the manufacturers. This is again cheap politics. The idea behind it is simple, GOI knows that almost all the states are strapped for cash. This is not new news, this I have shared a couple of months back. The problem has been that for the last 6-8 months no GST meeting has taken place as shared by Punjab s Finance Minister Amarinder Singh. What will happen is that all the states will fight in-between themselves for the vaccine and most of them are now non-BJP Governments. The idea is let the states fight and somehow be on top. So, the pandemic, instead of being a public health issue has become something of on which politics has to played. The news on whatsapp by RW media is it s ok even if a million or two also die, as it is India is heavily populated. Although that argument vanishes for those who lose their dear and near ones. But that just isn t the issue, the issue goes much more deeper than that Oxygen:12%
Remedisivir:12%
Sanitiser:12%
Ventilator:12%
PPE:18%
Ambulances 28% Now all the products above are essential medical equipment and should be declared as essential medical equipment and should have price controls on which GST is levied. In times of pandemic, should the center be profiting on those. States want to let go and even want the center to let go so that some relief is there to the public, while at the same time make them as essential medical equipment with price controls. But GOI doesn t want to. Leaders of opposition parties wrote open letters but no effect. What is sad to me is how Ambulances are being taxed at 28%. Are they luxury items or sin goods ? This also reminds of the recent discovery shared by Mr. Pappu Yadav in Bihar. You can see the color of ambulances as shared by Mr. Yadav, and the same news being shared by India TV news showing other ambulances. Also, the weak argument being made of not having enough drivers. Ideally, you should have 2-3 people, both 9-1-1 and Chicago Fire show 2 people in ambulance but a few times they have also shown to be flipped over. European seems to have three people in ambulance, also they are also much more disciplined as drivers, at least an opinion shared by an American expat.
Pappu Yadav, President Jan Adhikar Party, Bihar May 11, 2021
What is also interesting to note is GOI plays this game of Health is State subject and health is Central subject depending on its convenience. Last year, when it invoked the Epidemic and DMA Act it was a Central subject, now when bodies are flowing down the Ganges and pyres being lit everywhere, it becomes a State subject. But when and where money is involved, it again becomes a Central subject. The States are also understanding it, but they are fighting on too many fronts.
Snippets from Karnataka High Court hearing today, 13th March 2021
One of the good things is most of the High Courts have woken up. Many of the people on the RW think that the Courts are doing Judicial activism . And while there may be an iota of truth in it, the bitter truth is that many judges or relatives or their helpers have diagnosed and some have even died due to Covid. In face of the inevitable, what can they do. They are hauling up local Governments to make sure they are accountable while at the same time making sure that they get access to medical facilities. And I as a citizen don t see any wrong in that even if they are doing it for selfish reasons. Because, even if justice is being done for selfish reasons, if it does improve medical delivery systems for the masses, it is cool. If it means that the poor and everybody else are able to get vaccinations, oxygen and whatever they need, it is cool. Of course, we are still seeing reports of patients spending in the region of INR 50k and more for each day spent in hospital. But as there are no price controls, judges cannot do anything unless they want to make an enemy of the medical lobby in the country. A good story on medicines and what happens in rural areas, see no further than Laakhon mein ek.
Allahabad High Court hauling Uttar Pradesh Govt. for lack of Oxygen is equal to genocide, May 11, 2021
The censorship is not just related to takedown requests on twitter but nowadays also any articles which are critical of the GOI s handling. I have been seeing many articles which have shared facts and have been critical of GOI being taken down. Previously, we used to see 404 errors happen 7-10 years down the line and that was reasonable. Now we see that happen, days weeks or months. India seems to be turning more into China and North Korea and become more anti-science day-by-day

Fake websites Before going into fake websites, let me start with a fake newspaper which was started by none other than the Gujarat CM Mr. Modi in 2005 .
Gujarat Satya Samachar 2005 launched by Mr. Modi.
And if this wasn t enough than on Feb 8, 2005, he had invoked Official Secrets Act
Mr. Modi invoking Official Secrets Act, Feb 8 2005 Gujarat Samachar
The headlines were In Modi s regime press freedom is in peril-Down with Modi s dictatorship. So this was a tried and tested technique. The above information was shared by Mr. Urvish Kothari, who incidentally also has his own youtube channel. Now cut to 2021, and we have a slew of fake websites being done by the same party. In fact, it seems they started this right from 2011. A good article on BBC itself tells the story. Hell, Disinfo.eu which basically combats disinformation in EU has a whole pdf chronicling how BJP has been doing it. Some of the sites it shared are

Times of New York
Manchester Times
Times of Los Angeles
Manhattan Post
Washington Herald
and many more. The idea being take any site name which sounds similar to a brand name recognized by Indians and make fool of them. Of course, those of who use whois and other such tools can easily know what is happening. Two more were added to the list yesterday, Daily Guardian and Australia Today. There are of course, many features which tell them apart from genuine websites. Most of these are on shared hosting rather than dedicated hosting, most of these are bought either from Godaddy and Bluehost. While Bluehost used to be a class act once upon a time, both the above will do anything as long as they get money. Don t care whether it s a fake website or true. Capitalism at its finest or worst depending upon how you look at it. But most of these details are lost on people who do not know web servers, at all and instead think see it is from an exotic site, a foreign site and it chooses to have same ideas as me. Those who are corrupt or see politics as a tool to win at any cost will not see it as evil. And as a gentleman Raghav shared with me, it is so easy to fool us. An example he shared which I had forgotten. Peter England which used to be an Irish brand was bought by Aditya Birla group way back in 2000. But even today, when you go for Peter England, the way the packaging is done, the way the prices are, more often than not, people believe they are buying the Irish brand. While sharing this, there is so much of Naom Chomsky which comes to my mind again and again

Caste Issues I had written about caste issues a few times on this blog. This again came to the fore as news came that a Hindu sect used forced labor from Dalit community to make a temple. This was also shared by the hill. In both, Mr. Joshi doesn t tell that if they were volunteers then why their passports have been taken forcibly, also I looked at both minimum wage prevailing in New Jersey as a state as well as wage given to those who are in the construction Industry. Even in minimum wage, they were giving $1 when the prevailing minimum wage for unskilled work is $12.00 and as Mr. Joshi shared that they are specialized artisans, then they should be paid between $23 $30 per hour. If this isn t exploitation, then I don t know what is. And this is not the first instance, the first instance was perhaps the case against Cisco which was done by John Doe. While I had been busy with other things, it seems Cisco had put up both a demurrer petition and a petition to strike which the Court stayed. This seemed to all over again a type of apartheid practice, only this time applied to caste. The good thing is that the court stayed the petition. Dr. Ambedkar s statement if Hindus migrate to other regions on earth, Indian caste would become a world problem given at Columbia University in 1916, seems to be proven right in today s time and sadly has aged well. But this is not just something which is there only in U.S. this is there in India even today, just couple of days back, a popular actress Munmun Dutta used a casteist slur and then later apologized giving the excuse that she didn t know Hindi. And this is patently false as she has been in the Bollywood industry for almost now 16-17 years. This again, was not an isolated incident. Seema Singh, a lecturer in IIT-Kharagpur abused students from SC, ST backgrounds and was later suspended. There is an SC/ST Atrocities Act but that has been diluted by this Govt. A bit on the background of Dr. Ambedkar can be found at a blog on Columbia website. As I have shared and asked before, how do we think, for what reason the Age of Englightenment or the Age of Reason happened. If I were a fat monk or a priest who was privileges, would I have let Age of Enlightenment happen. It broke religion or rather Church which was most powerful to not so powerful and that power was more distributed among all sort of thinkers, philosophers, tinkers, inventors and so on and so forth.

Situation going forward I believe things are going to be far more complex and deadly before they get better. I had to share another term called Comorbidities which fortunately or unfortunately has also become part of twitter lexicon. While I have shared what it means, it simply means when you have an existing ailment or condition and then Coronavirus attacks you. The Virus will weaken you. The Vaccine in the best case just stops the damage, but the damage already done can t be reversed. There are people who advise and people who are taking steroids but that again has its own side-effects. And this is now, when we are in summer. I am afraid for those who have recovered, what will happen to them during the Monsoons. We know that the Virus attacks most the lungs and their quality of life will be affected. Even the immune system may have issues. We also know about the inflammation. And the grant that has been given to University of Dundee also has signs of worry, both for people like me (obese) as well as those who have heart issues already. In other news, my city which has been under partial lockdown since a month, has been extended for another couple of weeks. There are rumors that the same may continue till the year-end even if it means economics goes out of the window.There is possibility that in the next few months something like 2 million odd Indians could die
The above is a conversation between Karan Thapar and an Oxford Mathematician Dr. Murad Banaji who has shared that the under-counting of cases in India is huge. Even BBC shared an article on the scope of under-counting. Of course, those on the RW call of the evidence including the deaths and obituaries in newspapers as a narrative . And when asked that when deaths used to be in the 20 s or 30 s which has jumped to 200-300 deaths and this is just the middle class and above. The poor don t have the money to get wood and that is the reason you are seeing the bodies in Ganges whether in Buxar Bihar or Gajipur, Uttar Pradesh. The sights and visuals makes for sorry reading
Pandit Ranjan Mishra son on his father s death due to unavailability of oxygen, Varanasi, Uttar Pradesh, 11th May 2021.
For those who don t know Pandit Ranjan Mishra was a renowned classical singer. More importantly, he was the first person to suggest Mr. Modi s name as a Prime Ministerial Candidate. If they couldn t fulfil his oxygen needs, then what can be expected for the normal public.

Conclusion Sadly, this time I have no humorous piece to share, I can however share a documentary which was shared on Feluda . I have shared about Feluda or Prodosh Chandra Mitter a few times on this blog. He has been the answer of James Bond from India. I have shared previously about The Golden Fortress . An amazing piece of art by Satyajit Ray. I watched that documentary two-three times. I thought, mistakenly that I am the only fool or fan of Feluda in Pune to find out that there are people who are even more than me. There were so many facets both about Feluda and master craftsman Satyajit Ray that I was unaware about. I was just simply amazed. I even shared few of the tidbits with mum as well, although now she has been truly hooked to Korean dramas. The only solace from all the surrounding madness. So, if you have nothing to do, you can look up his books, read them and then see the movies. And my first recommendation would be the Golden Fortress. The only thing I would say, do not have high hopes. The movie is beautiful. It starts slow and then picks up speed, just like a train. So, till later. Update The Mass surveillance part I could not do justice do hence removed it at the last moment. It actually needs its whole space, article. There is so much that the Govt. is doing under the guise of the pandemic that it is difficult to share it all in one article. As it is, the article is big

Matthew Garrett: The importance of paying attention in building community trust

Trust is important in any kind of interpersonal relationship. It's inevitable that there will be cases where something you do will irritate or upset others, even if only to a small degree. Handling small cases well helps build trust that you will do the right thing in more significant cases, whereas ignoring things that seem fairly insignificant (or saying that you'll do something about them and then failing to do so) suggests that you'll also fail when there's a major problem. Getting the small details right is a major part of creating the impression that you'll deal with significant challenges in a responsible and considerate way.

This isn't limited to individual relationships. Something that distinguishes good customer service from bad customer service is getting the details right. There are many industries where significant failures happen infrequently, but minor ones happen a lot. Would you prefer to give your business to a company that handles those small details well (even if they're not overly annoying) or one that just tells you to deal with them?

And the same is true of software communities. A strong and considerate response to minor bug reports makes it more likely that users will be patient with you when dealing with significant ones. Handling small patch contributions quickly makes it more likely that a submitter will be willing to do the work of making more significant contributions. These things are well understood, and most successful projects have actively worked to reduce barriers to entry and to be responsive to user requests in order to encourage participation and foster a feeling that they care.

But what's often ignored is that this applies to other aspects of communities as well. Failing to use inclusive language may not seem like a big thing in itself, but it leaves people with the feeling that you're less likely to do anything about more egregious exclusionary behaviour. Allowing a baseline level of sexist humour gives the impression that you won't act if there are blatant displays of misogyny. The more examples of these "insignificant" issues people see, the more likely they are to choose to spend their time somewhere else, somewhere they can have faith that major issues will be handled appropriately.

There's a more insidious aspect to this. Sometimes we can believe that we are handling minor issues appropriately, that we're acting in a way that handles people's concerns, while actually failing to do so. If someone raises a concern about an aspect of the community, it's important to discuss solutions with them. Putting effort into "solving" a problem without ensuring that the solution has the desired outcome is not only a waste of time, it alienates those affected even more - they're now not only left with the feeling that they can't trust you to respond appropriately, but that you will actively ignore their feelings in the process.

It's not always possible to satisfy everybody's concerns. Sometimes you'll be left in situations where you have conflicting requests. In that case the best thing you can do is to explain the conflict and why you've made the choice you have, and demonstrate that you took this issue seriously rather than ignoring it. Depending on the issue, you may still alienate some number of participants, but it'll be fewer than if you just pretend that it's not actually a problem.

One warning, though: while building trust in this way enhances people's willingness to join your community, it also builds expectations. If a significant issue does arise, and if you fail to handle it well, you'll burn a lot of that trust in the process. The fact that you've built that trust in the first place may be what saves your community from disintegrating completely, but people will feel even more betrayed if you don't actively work to rebuild it. And if there's a pattern of mishandling major problems, no amount of getting the details right will matter.

Communities that ignore these issues are, long term, likely to end up weaker than communities that pay attention to them. Making sure you get this right in the first place, and setting expectations that you will pay attention to your contributors, is a vital part of building a meaningful relationship between your community and its members.

Chris Lamb: Free software activities in August 2016

Here is my monthly update covering what I have been doing in the free software world (previously):

Reproducible builds

Whilst anyone can inspect the source code of free software for malicious flaws, most Linux distributions provide binary (or "compiled") packages to end users. The motivation behind the Reproducible Builds effort is to allow verification that no flaws have been introduced either maliciously and accidentally during this compilation process by promising identical binary packages are always generated from a given source.

Diffoscope diffoscope is our "diff on steroids" that will not only recursively unpack archives but will transform binary formats into human-readable forms in order to compare them:
  • Added a command-line interface to the try.diffoscope.org web service.
  • Added a JSON comparator.
  • In the HTML output, highlight lines when hovering to make it easier to visually track.
  • Ensure that we pass str types to our Difference class, otherwise we can't be sure we can render them later.
  • Testsuite improvements:
    • Generate test coverage reports.
    • Add tests for Haskell and GitIndex comparators.
    • Completely refactored all of the comparator tests, extracting out commonly-used routines.
    • Confirm rendering of text and HTML presenters when checking non-existing files.
    • Dropped a squashfs test as it was simply too unreliable and/or has too many requirements to satisfy.
  • A large number of miscellaneous cleanups, including:
    • Reworking the comparator setup/preference internals by dynamically importing classes via a single list.
    • Split exceptions out into dedicated diffoscope.exc module.
    • Tidying the PROVIDERS dict in diffoscope/__init__.py.
    • Use html.escape over xml.sax.saxutils.escape, cgi.escape, etc.
    • Removing hard-coding of manual page targets names in debian/rules.
    • Specify all string format arguments as logging function parameters, not using interpolation.
    • Tidying imports, correcting indentation levels and drop unnecessary whitespace.

disorderfs disorderfs is our FUSE filesystem that deliberately introduces nondeterminism in system calls such as readdir(3).
  • Added a testsuite to prevent regressions. (f124965)
  • Added a --sort-dirents=yes no option for forcing deterministic ordering. (2aae325)

Other
  • Improved strip-nondeterminism, our tool to remove specific nondeterministic information after a build:
    • Match more styles of Java .properties files.
    • Remove hyphen from "non-determinism" and "non-deterministic" throughout package for consistency.
  • Improvements to our testing infrastucture:
    • Improve the top-level navigation so that we can always get back to "home" of a package.
    • Give expandable elements cursor: pointer CSS styling to highlight they are clickable.
    • Drop various trailing underlined whitespaces after links.
    • Explicitly log that build was successful or not.
    • Various code-quality improvements, including prefering str.format over concatentation.
  • Miscellaneous updates to our filter-packages internal tool:
    • Add --random=N and --url options.
    • Add support for --show=comments.
    • Correct ordering so that --show-version runs after --filter-ftbfs.
    • Rename --show-ftbfs to --filter-ftbfs and --show-version to --show=version.
  • Created a proof-of-concept reproducible-utils package to contain commonly-used snippets aimed at developers wishing to make their packages reproducible.


I also submitted 92 patches to fix specific reproducibility issues in advi, amora-server, apt-cacher-ng, ara, argyll, audiotools, bam, bedtools, binutils-m68hc1x, botan1.10, broccoli, congress, cookiecutter, dacs, dapl, dateutils, ddd, dicom3tools, dispcalgui, dnssec-trigger, echoping, eekboek, emacspeak, eyed3, fdroidserver, flashrom, fntsample, forkstat, gkrellm, gkrellm, gnunet-gtk, handbrake, hardinfo, ircd-irc2, ircd-ircu, jack-audio-connection-kit, jpy, kxmlgui, libbson, libdc0, libdevel-cover-perl, libfm, libpam-ldap, libquvi, librep, lilyterm, mozvoikko, mp4h, mp4v2, myghty, n2n, nagios-nrpe, nikwi, nmh, nsnake, openhackware, pd-pdstring, phpab, phpdox, phpldapadmin, pixelmed-codec, pleiades, pybit, pygtksourceview, pyicu, python-attrs, python-gflags, quvi, radare2, rc, rest2web, roaraudio, rt-extension-customfieldsonupdate, ruby-compass, ruby-pg, sheepdog, tf5, ttf-tiresias, ttf-tiresias, tuxpaint, tuxpaint-config, twitter-bootstrap3, udpcast, uhub, valknut, varnish, vips, vit, wims, winswitch, wmweather+ & xshisen.

Debian GNU/Linux
Debian LTS

This month I have been paid to work 15 hours on Debian Long Term Support (LTS). In that time I did the following:
  • "Frontdesk" duties, triaging CVEs, etc.
  • Authored the patch & issued DLA 596-1 for extplorer, a web-based file manager, fixing an archive traversal exploit.
  • Issued DLA 598-1 for suckless-tools, fixing a segmentation fault in the slock screen locking tool.
  • Issued DLA 599-1 for cracklib2, a pro-active password checker library, fixing a stack-based buffer overflow when parsing large GECOS fields.
  • Improved the find-work internal tool adding optional colour highlighting and migrating it to Python 3.
  • Wrote an lts-missing-uploads tool to find mistakes where there was no correponding package in the archive after an announcement.
  • Added optional colour highlighting to the lts-cve-triage tool.

Uploads
  • redis 2:3.2.3-1 New upstream release, move to the DEP-5 debian/copyright format, ensure that we are running as root in LSB initscripts and add a README.Source regarding our local copies of redis.conf and sentinel.conf.
  • python-django:
    • 1:1.10-1 New upstream release.
    • 1:1.10-2 Fix test failures due to mishandled upstream translation updates.

  • gunicorn:
    • 19.6.0-2 Reload logrotate in the postrotate action to avoid processes writing to the old files and move to DEP-5 debian/copyright format.
    • 19.6.0-3 Drop our /usr/sbin/gunicorn ,3 -debian and related Debian-specific machinery to be more like upstream.
    • 19.6.0-4 Drop "template" systemd .service files and point towards examples and documentation instead.

  • adminer:

Russ Allbery: Review: The Run of His Life

Review: The Run of His Life, by Jeffrey Toobin
Publisher: Random House
Copyright: 1996, 1997

ISBN: 0-307-82916-2
Format: Kindle
Pages: 498
The O.J. Simpson trial needs little introduction to anyone who lived through it in the United States, but a brief summary for those who didn't. O.J. Simpson is a Hall of Fame football player and one of the best running backs to ever play the game. He's also black, which is very relevant much of what later happened. After he retired from professional play, he became a television football commentator and a spokesperson for various companies (particularly Hertz, a car rental business). In 1994, he was arrested for the murder of two people: his ex-wife, Nicole Brown Simpson, and Ron Goldman (a friend of Nicole's). The arrest happened after a bizarre low-speed police chase across Los Angeles in a white Bronco that was broadcast live on network television. The media turned the resulting criminal trial into a reality TV show, with live cable television broadcasts of all of the court proceedings. After nearly a full year of trial (with the jury sequestered for nine months more on that later), a mostly black jury returned a verdict of not guilty after a mere four hours of deliberation. Following the criminal trial, in an extremely unusual legal proceeding, Simpson was found civilly liable for Ron Goldman's death in a lawsuit brought by his family. Bizarre events surrounding the case continued long afterwards. A book titled If I Did It (with "if" in very tiny letters on the cover) was published, ghost-written but allegedly with Simpson's input and cooperation, and was widely considered a confession. Another legal judgment let the Goldman family get all the profits from that book's publication. In an unrelated (but also bizarre) incident in Las Vegas, Simpson was later arrested for kidnapping and armed robbery and is currently in prison until at least 2017. It is almost impossible to have lived through the O.J. Simpson trial in the United States and not have formed some opinion on it. I was in college and without a TV set at the time, and even I watched some of the live trial coverage. Reactions to the trial were extremely racially polarized, as you might have guessed. A lot of black people believed at the time that Simpson was innocent (probably fewer now, given subsequent events). A lot of white people thought he was obviously guilty and was let off by a black jury for racial reasons. My personal opinion, prior to reading this book, was a common "third way" among white liberals: Simpson almost certainly committed the murders, but the racist Los Angeles police department decided to frame him for a crime that he did commit by trying to make the evidence stronger. That's a legitimate reason in the US justice system for finding someone innocent: the state has an obligation to follow correct procedure and treat the defendant fairly in order to get a conviction. I have a strong bias towards trusting juries; frequently, it seems that the media second-guesses the outcome of a case that makes perfect sense as soon as you see all the information the jury had (or didn't have). Toobin's book changed my mind. Perhaps because I wasn't watching all of the coverage, I was greatly underestimating the level of incompetence and bad decision-making by everyone involved: the prosecution, the defense, the police, the jury, and the judge. This court case was a disaster from start to finish; no one involved comes away looking good. Simpson was clearly guilty given the evidence presented, but the case was so badly mishandled that it gave the jury room to reach the wrong verdict. (It's telling that, in the far better managed subsequent civil case, the jury had no trouble reaching a guilty verdict.) The Run of His Life is a very detailed examination of the entire Simpson case, from the night of the murder through the end of the trial and (in an epilogue) the civil case. Toobin was himself involved in the media firestorm, breaking some early news of the defense's decision to focus on race in The New Yorker and then involved throughout the trial as a legal analyst, and he makes it clear when he becomes part of the story. But despite that, this book felt objective to me. There are tons of direct quotes, lots of clear description of the evidence, underlying interviews with many of the people involved to source statements in the book, and a comprehensive approach to the facts. I think Toobin is a bit baffled by the black reaction to the case, and that felt like a gap in the comprehensiveness and the one place where he might be accused of falling back on stereotypes and easy judgments. But other than hole, Toobin applies his criticism even-handedly and devastatingly to all parties. I won't go into all the details of how Toobin changed my mind. It was a cumulative effect across the whole book, and if you're curious, I do recommend reading it. A lot was the detailed discussion of the forensic evidence, which was undermined for the jury at trial but looks very solid outside the hothouse of the case. But there is one critical piece that I would hope would be handled differently today, twenty years later, than it was by the prosecutors in that case: Simpson's history of domestic violence against Nicole. With what we now know about patterns of domestic abuse, the escalation to murder looks entirely unsurprising. And that history of domestic abuse was exceedingly well-documented: multiple external witnesses, police reports, and one actual prior conviction for spousal abuse (for which Simpson did "community service" that was basically a joke). The prosecution did a very poor job of establishing this history and the jury discounted it. That was a huge mistake by both parties. I'll mention one other critical collection of facts that Toobin explains well and that contradicted my previous impression of the case: the relationship between Simpson and the police. Today, in the era of Black Lives Matter, the routine abuse of black Americans by the police is more widely known. At the time of the murders, it was less recognized among white Americans, although black Americans certainly knew about it. But even in 1994, the Los Angeles police department was notorious as one of the most corrupt and racist big-city police departments in the United States. This is the police department that beat Rodney King. Mark Fuhrman, one of the police officers involved in the case (although not that significantly, despite his role at the trial), was clearly racist and had no business being a police officer. It was therefore entirely believable that these people would have decided to frame a black man for a murder he actually committed. What Toobin argues, quite persuasively and with quite a lot of evidence, is that this analysis may make sense given the racial tensions in Los Angeles but ignores another critical characteristic of Los Angeles politics, namely a deference to celebrity. Prior to this trial, O.J. Simpson largely followed the path of many black athletes who become broadly popular in white America: underplaying race and focusing on his personal celebrity and connections. (Toobin records a quote from Simpson earlier in his life that perfectly captures this approach: "I'm not black, I'm O.J.") Simpson spent more time with white businessmen than the black inhabitants of central Los Angeles. And, more to the point, the police treated him as a celebrity, not as a black man. Toobin takes some time to chronicle the remarkable history of deference and familiarity that the police showed Simpson. He regularly invited police officers to his house for parties. The police had a long history of largely ignoring or downplaying his abuse of his wife, including not arresting him in situations that clearly seemed to call for that, showing a remarkable amount of deference to his side of the story, not pursuing clear violations of the court judgment after his one conviction for spousal abuse, and never showing much inclination to believe or protect Nicole. Even on the night of the murder, they started following a standard playbook for giving a celebrity advance warning of investigations that might involve them before the news media found out about them. It seems clear, given the evidence that Toobin collected, that the racist Los Angeles police didn't focus that animus at Simpson, a wealthy celebrity living in Brentwood. He wasn't a black man in their eyes; he was a rich Hall of Fame football player and a friend. This obviously raises the question of how the jury could return an innocent verdict. Toobin provides plenty of material to analyze that question from multiple angles in his detailed account of the case, but I can tell you my conclusion: Judge Lance Ito did a horrifically incompetent job of managing the case. He let the lawyers wander all over the case, interacted bizarrely with the media coverage (and was part of letting the media turn it into a daytime drama), was not crisp or clear about his standards of evidence and admissibility, and, perhaps worst of all, let the case meander on at incredible length. With a fully sequestered jury allowed only brief conjugal visits and no media contact (not even bookstore shopping!). Quite a lot of anger was focused on the jury after the acquittal, and I do think they reached the wrong conclusion and had all the information they would have needed to reach the correct one. But Toobin touches on something that I think would be very hard to comprehend without having lived through it. The jury and alternate pool essentially lived in prison for nine months, with guards and very strict rules about contact with the outside world, in a country where compensation for jury duty is almost nonexistent. There were a lot of other factors behind their decision, including racial tensions and the sheer pressure from judging a celebrity case about which everyone has an opinion, but I think it's nearly impossible to underestimate the psychological tension and stress from being locked up with random other people under armed guard for three quarters of a year. It's hard for jury members to do an exhaustive and careful deliberation in a typical trial that takes a week and doesn't involve sequestration. People want to get back to their lives and families. I can only imagine the state I would be in after nine months of this, or how poor psychological shape I would be in to make a careful and considered decision. Similarly, for those who condemned the jury for profiting via books and media appearances after the trial, the current compensation for jurors is $15 per day (not hour). I believe at the time it was around $5 per day. There are a few employers who will pay full salary for the entire jury service, but only a few; many cap the length at a few weeks, and some employers treat all jury duty as unpaid leave. The only legal requirement for employers in the United States is that employees that serve on a jury have their job held for them to return to, but compensation is pathetic, not tied to minimum wage, and employers do not have to supplement it. I'm much less inclined to blame the jurors than the system that badly mistreated them. As you can probably tell from the length of this review, I found The Run of His Life fascinating. If I had followed the whole saga more closely at the time, this may have been old material, but I think my vague impressions and patchwork of assumptions were more typical than not among people who were around for the trial but didn't invest a lot of effort into following it. If you are like me, and you have any interest in the case or the details of how the US criminal justice system works, this is a fascinating case study, and Toobin does a great job with it. Recommended. Rating: 8 out of 10

Iain R. Learmonth: YubiKey NEO as an OpenPGP token

I was first interested in the idea of using a smartcard to store OpenPGP subkeys when I joined the Free Software Foundation Europe as a Fellow and recieved my FSFE Fellowship Card. By performing all cryptographic operations on the smartcard it would remove almost all the routes by which the secret key material could be compromised as the host operating system never has access to that secret material. I decided that this was something I wanted to try out and I purchased two Cherry G83-6644 keyboards. One of the nice things I noticed about this product was that it was both FIPS 201 approved and GOST R approved. If both the Americans and the Russians could agree it was a good keyboard, it had a good chance of being a good keyboard. A little udev magic to handle permissions and the card worked great, but there was a problem. This was not the most friendly form-factor and a USB keyboard was a bit big to be carrying around to use the smartcard with my laptop. I intended to get a smaller reader for my laptop but never did and the Fellowship card fell into disuse. Later, I came across the YubiKey NEO. The YubiKey NEO is capable of emulating an OpenPGP smartcard, just like the Fellowship card, but in the form-factor of a USB stick. This improved form factor was enough to make me give it a go. Since August 2015 I've been using a YubiKey NEO to store my OpenPGP subkeys and, excluding some occasional udev mishaps, it's been working great. When you first get the YubiKey NEO, it does not have the OpenPGP applet enabled. You'll need to enable it yourself using the ykpersonalize tool:
sudo apt install yubikey-personalization  
sudo ykpersonalize -m 82  
Once you've enabled the OpenPGP module, the USB product ID will change, and you can now add a udev rule that will allow you to interact with the device when it's plugged in as your normal user.
/etc/udev/rules.d/99-yubikeys.rules:
------------------------------------
SUBSYSTEMS=="usb", ATTRS idVendor =="1050",ATTRS idProduct =="0111", OWNER="irl"  
This is not the correct way to do this. I've set it so that any YubiKey with the OpenPGP module inserted is set to be owned by my username (irl) when the correct way to do this would be to have it set to the current console user. I do not know enough udev magic to know how to do that. UPDATE: I recieved a lot of good feedback on this, which you can find here. Of course, for my key 0xE9846C49, this key started life as an ordinary key just stored on my laptop, so seperating subkeys onto the YubiKey has not massively increased security as an attacker that has stolen the secret key material can generate new subkeys. I would hopefully notice these new rogue subkeys (I do monitor keyservers for changes to my key regularly), but I would prefer to make the possibility of the key being compromised as low as possible. For this reason I am performing a key transition to a new key, F540ABCD, where the master key is stored offline. In my next post, hopefully within a day or so, I'll explain how I used Tails to generate a key offline and load the subkeys into the YubiKey.

Jaldhar Vyas: Mini-Debconf Mumbai 2015

Last weekend I went to Mumbai to attend the Mini-Debconf held at IIT-Bombay. These are my impressions of the trip. Arrival and Impressions of Mumbai Getting there was a quite an adventure in itself. Unlike during my ill-fated attempt to visit a Debian event in Kerala last year when a bureaucratic snafu left me unable to get a visa, the organizers started the process much earlier at their end this time and with proper permissions. Yet in India, the wheels only turn as fast as they want to turn so despite their efforts, it was only literally at the last minute that I actually managed to secure my visa. I should note however that Indian government has done a lot to improve the process compared to the hell I remember from, say, a decade ago. It's fairly straightforward for tourist visas now and I trust they will get around to doing the same for conference visas in the fullness of time. I didn't want to commit to buying a plane ticket until I had the visa so I became concerned that the only flights left would be either really expensive or on the type of airline that flies you over Syria or under the Indian Ocean. I lucked out and got a good price on a Swiss Air flight, not non-stop but you can't have everything. So Thursday afternoon I set off for JFK. With only one small suitcase getting there by subway was no problem and I arrived and checked in with plenty of time. Even TSA passed me through with only a minimal amount of indignity. The first leg of my journey took me to Zurich in about eight hours. We were only in Zurich for an hour and then (by now Friday) it was another 9 hours to Mumbai. Friday was Safala Ekadashi but owing to the necessity of staying hydrated on a long flight I drank a lot of water and ate some fruit which I don't normally do on a fasting day. It was tolerable but not too pleasant; I definitely want to try and make travel plans to avoid such situations in the future. Friday evening local time I got to Mumbai. Chhattrapati Shivaji airport has improved a lot since I saw t last and now has all the amenities an international traveller needs including unrestricted free wifi (Zurich airport are you taking notes?) But here my first ominous piece of bad luck began. No sign of my suitcase. Happily some asking around revealed that it had somehow gotten on some earlier Swiss Air flight instead of the one I was on and was actually waiting for me. I got outside and Debian Developer Praveen Arimbrathodiyil was waiting to pick me up. Normally I don't lke staying in Mumbai very much even though I have relatives there but that's because we usually went during July-August the monsoon season when Mumbai reverts back to the swampy archipelago it was originally built on. This time the weather was nice, cold by local standards, but lovely and spring-like to someone from snowy New Jersey. There have been a lot of improvements to the road infrastructure and people are actually obeying the traffic laws. (Within reason of course. Whether or not a family of six can arrange themselves on one Bajaj scooter is no business of the cops.) The Hotel Tuliip (yes, two i's. Manager didn't know why.) Residency where I was to stay while not quite a five star establishment was adequate for my needs with a bed, hot water shower, and air conditioning. And a TV which to the bellhops great confusion I did not want turned on. (He asked about five times.) There was no Internet access per se but the manager offered to hook up a wireless router to a cable. Which on closer inspection turned out to have been severed at the base. He assured me it would be fixed tomorrow so I didn't complain and decided to do something more productive thank checking my email like sleeping. The next day I woke up in total darkness. Apparently there had been some kind of power problem during the night which tripped a fuse or something. A call to the front desk got them to fix that and then the second piece of bad luck happened. I plugged my Thinkpad in and woke it up from hibernation and a minute later there was a loud pop from the power adapter. Note I have a travel international plug adapter with surge protector so nothing bad ought to have happened but the laptop would on turning on display the message "critical low battery error" and immediately power off. I was unable to google what that meant without Internet access but I decided not to panic and continue getting ready. I would have plenty of opportunity to troubleshoot at the conference venue. Or so I thought... I took an autorickshaw to IIT. There also there have been positive improvements. Being quite obviously a foreigner I was fully prepared to be taken along the "scenic route." But now there are fair zones and the rickshaws all have (tamperproof!) digital fare meters so I was deposited at the main gate without fuss. After reading a board with a scary list of dos and don'ts I presented myself at security only to be inexplicably waved through without a second glance. Later I found out they've abandoned all the security theatre but not got around to updating the signs yet. Mumbai is one of the biggest, densely populated cities in the world but the IIT campus is an oasis of tranquility on the shores of Lake Powai. It's a lot bigger than it looked on the map so I had to wander around a bit before I reached the conference venue but I did make for the official registration time. Registration I was happy to meet several old friends (Such as Kartik Mistry and Kumar Appiah who along with Praveen and myself were the other DDs there,) people who I've corresponded with but never met, and many new people. I'm told 200+ people registered altogether. Most seemed to be students from IIT and elsewhere in Mumbai but there were also some Debian enthusiasts from further afield and most hearteningly some "civilians" who wanted to know what this was all about. With the help of a borrowed Thinkpad adapter I got my laptop running again. (Thankfully, despite the error message, the battery itself was unharmed.) However, my streak of bad luck was not yet over. It was that very weekend that IIT had a freak campus-wide network outage something that had never happened before. And as the presentation for the talk I was to give had apparently been open when I hibernated my laptop the night before, the sudden forced shutdown had trashed the file. (ls showed it as 0 length. An fsck didn't help.) I possibly had a backup on my server but with no Internet access I had no way to retrieve it. I still remained cool. The talk was scheduled for the second day so I could recover it at the hotel. Keynotes Professor Kannan Maudgalya of the FOSSEE (Free and Open Source Software for Education) Project which is part of the central government Ministry for Human Resource Development spoke about various activities of his project. Of particular interest to us are: FOSSEE is well funded, backed by the government and has enthusiastic staff so we should be seeing a lot more from them in the future. Veteran Free Software activist Venky Hariharan spoke about his experiences in lobbying the government on tech issues. He noted that there has been a sea change in attitudes towards Linux and Open source in the bureacracy of late. Several states have been aggressively mandating the use of it as have several national ministries and agencies. We the community can provide a valuable service by helping them in the transition. They also need to be educated on how to work with the community (contributing changes back, not working behind closed doors etc.) Debian History and Debian Cycle Shirish Agarwal spoke about the Debian philosophy and foundational documents such as the social contract and DFSG and how the release cycle works. Nothing new to an experienced user but informative to the newcomers in the audience and sparked some questions and discussion. Keysigning One of my main missions in attending was to help get as many isolated people as possible into the web of trust. Unfortunately the keysigning was not adequately publicized and few people were ready. I would have led them through the process of creating a new key there and then but with the lack of connectivity that idea had to be abandoned. I did manage to sign about 8-10 keys during other times. Future Directions for Debian-IN BOF I led this one. Lots of spirited discussion and I found feedback from new users in particular to be very helpful. Some take aways are: Lil' Debi Kumar Sukhani was a Debian GSoC student and his project which he demonstrated was to be able to install Debian on an Android phone. Why would you want to do this? Apart from the evergreen "Because I can", you can run server software such as sshd on your phone or even use it as an ARM development board. Unfortunately my phone uses Blackberry 10 OS which can run android apps (emulated under QNX) but wouldn't be able to use this. When I get a real Android phone I will try it out. Debian on ARM Siji Sunny gave this talk which was geared more towards hardware types which I am not but one thing I learned was thee difference between all the different ARM subarchitectures. I knew Siji first from a previous incarnation when he worked at CDAC with the late and much lamented Prof. R.K. Joshi. We had a long conversation about those days. Prof. Joshi/CDAC had developed an Indic rendering system called Indix which alas became the Betamax to Pango's VHS but he was also very involved in other Indic computing issues such as working with the Unicode Consortium and the preseration of Sanskrit manuscripts which is also an interest of mine. One good thing that cameout of Indix was some rather nice fonts. I had thought they were still buried in the dungeons of CDAC but apparently they were freed at one point. That's one more thing for me to look into. Evening/Next morning< My cousin met me and we had a leisurely dinner together. It was quite late by the time I got back to the hotel. FOSSEE had kindly lent me one of their tablets (which incidently are powerful enough to run LibreOffice comfortably.) so I thought I might be able to quickly redo my presentation before bedtime. Well, wouldn't you know it the wifi was not fixed. As I should have guessed but all the progress I'd had made me giddily optimistic. There was an option of trying to find an Internet cafe in a commercial area 15-20 minutes walk away. If this had been Gujarat I would have tried it but although I can more or less understand Hindi I can barely put together two sentences and Marathi I don't know at all. So I gave up that idea. I redid the slides from memory as best I could and went to sleep. In the morning I checked out and ferried myself and my suitcase via rickshaw back to the IIT campus. This time I got the driver to take me all the way in to the conference venue. Prof. Maudgalya kindly offered to let me keep the tablet to develop stuff on. I respectfully had to decline because although I love to collect bits of tech the fact it is it would have just gathered dust and ought to go to someone who can make a real contribution with it. I transferred my files to a USB key and borrowed a loaner laptop for my talk. Debian Packaging Workshop While waiting to do my talk I sat in on a workshop Praveen ran taking participants through the whole process of creating a Debian package (a ruby gem was the example.) He's done this before so it was a good presentation and well attended but the lack of connectivity did put a damper on things. Ask Me Anything It turned out the schedule had to be shuffled a bit so my talk was moved later from the announced time. A few people had already showed up so I took some random questions about Debian from them instead. GNOME Shell Accessibility With Orca Krishnakant Mane is remarkable. Although he is blind, he is a developer and a major contributor to Open Source projects. He talked about the Accessibility features of GNOME and compared them (favorably I might add) with proprietary screen readers. Not a subject that's directly useful to me but I found it interesting nonetheless. Rust: The memory safe language Manish Goregaokar talked about one of the new fad programming languages that have gotten a lot of buzz lately. This one is backed by Mozilla and it's interesting enough but I'll stick with C++ and Perl until one of the new ones "wins." Building a Mail Server With Debian Finally I got to give my talk and, yup, the video out on my borrowed laptop was incompatible with the projector. A slight delay to transfer everything to another laptop and I was able to begin. I talked about setting up BIND, postfix, and of course dovecot along with spamassassin, clamav etc. It turned out I had more than enough material and I went atleast 30 minutes over time and even then I had to rush at the end. People said they liked it so I'm happy. The End I gave the concluding remarks. Various people were thanked (including myself) mementos were given and pictures were taken. Despite a few mishaps I enjoyed myself and I am glad I attended. The level of enthusiasm was very high and lessons were learned so the next Debian-IN event should be even better. My departing flight wasn't due to leave until 1:20AM so I killed a few hours with my family before the flight. Once again I was stopping in Zurich, this time for most of a day. The last of my blunders was not to take my coat out of my suitcase and the temperature outside was 29F so I had to spend that whole time enjoing the (not so) many charms of Zurich airport. Atleast the second flight took me to Newark instead of JFK so I was able to get home a little earlier on Monday evening, exhausted but happy I made the trip.

Matthew Garrett: ACPI, kernels and contracts with firmware

ACPI is a complicated specification - the latest version is 980 pages long. But that's because it's trying to define something complicated: an entire interface for abstracting away hardware details and making it easier for an unmodified OS to boot diverse platforms.

Inevitably, though, it can't define the full behaviour of an ACPI system. It doesn't explicitly state what should happen if you violate the spec, for instance. Obviously, in a just and fair world, no systems would violate the spec. But in the grim meathook future that we actually inhabit, systems do. We lack the technology to go back in time and retroactively prevent this, and so we're forced to deal with making these systems work.

This ends up being a pain in the neck in the x86 world, but it could be much worse. Way back in 2008 I wrote something about why the Linux kernel reports itself to firmware as "Windows" but refuses to identify itself as Linux. The short version is that "Linux" doesn't actually identify the behaviour of the kernel in a meaningful way. "Linux" doesn't tell you whether the kernel can deal with buffers being passed when the spec says it should be a package. "Linux" doesn't tell you whether the OS knows how to deal with an HPET. "Linux" doesn't tell you whether the OS can reinitialise graphics hardware.

Back then I was writing from the perspective of the firmware changing its behaviour in response to the OS, but it turns out that it's also relevant from the perspective of the OS changing its behaviour in response to the firmware. Windows 8 handles backlights differently to older versions. Firmware that's intended to support Windows 8 may expect this behaviour. If the OS tells the firmware that it's compatible with Windows 8, the OS has to behave compatibly with Windows 8.

In essence, if the firmware asks for Windows 8 support and the OS says yes, the OS is forming a contract with the firmware that it will behave in a specific way. If Windows 8 allows certain spec violations, the OS must permit those violations. If Windows 8 makes certain ACPI calls in a certain order, the OS must make those calls in the same order. Any firmware bug that is triggered by the OS not behaving identically to Windows 8 must be dealt with by modifying the OS to behave like Windows 8.

This sounds horrifying, but it's actually important. The existence of well-defined[1] OS behaviours means that the industry has something to target. Vendors test their hardware against Windows, and because Windows has consistent behaviour within a version[2] the vendors know that their machines won't suddenly stop working after an update. Linux benefits from this because we know that we can make hardware work as long as we're compatible with the Windows behaviour.

That's fine for x86. But remember when I said it could be worse? What if there were a platform that Microsoft weren't targeting? A platform where Linux was the dominant OS? A platform where vendors all test their hardware against Linux and expect it to have a consistent ACPI implementation?

Our even grimmer meathook future welcomes ARM to the ACPI world.

Software development is hard, and firmware development is software development with worse compilers. Firmware is inevitably going to rely on undefined behaviour. It's going to make assumptions about ordering. It's going to mishandle some cases. And it's the operating system's job to handle that. On x86 we know that systems are tested against Windows, and so we simply implement that behaviour. On ARM, we don't have that convenient reference. We are the reference. And that means that systems will end up accidentally depending on Linux-specific behaviour. Which means that if we ever change that behaviour, those systems will break.

So far we've resisted calls for Linux to provide a contract to the firmware in the way that Windows does, simply because there's been no need to - we can just implement the same contract as Windows. How are we going to manage this on ARM? The worst case scenario is that a system is tested against, say, Linux 3.19 and works fine. We make a change in 3.21 that breaks this system, but nobody notices at the time. Another system is tested against 3.21 and works fine. A few months later somebody finally notices that 3.21 broke their system and the change gets reverted, but oh no! Reverting it breaks the other system. What do we do now? The systems aren't telling us which behaviour they expect, so we're left with the prospect of adding machine-specific quirks. This isn't scalable.

Supporting ACPI on ARM means developing a sense of discipline around ACPI development that we simply haven't had so far. If we want to avoid breaking systems we have two options:

1) Commit to never modifying the ACPI behaviour of Linux.
2) Exposing an interface that indicates which well-defined ACPI behaviour a specific kernel implements, and bumping that whenever an incompatible change is made. Backward compatibility paths will be required if firmware only supports an older interface.

(1) is unlikely to be practical, but (2) isn't a great deal easier. Somebody is going to need to take responsibility for tracking ACPI behaviour and incrementing the exported interface whenever it changes, and we need to know who that's going to be before any of these systems start shipping. The alternative is a sea of ARM devices that only run specific kernel versions, which is exactly the scenario that ACPI was supposed to be fixing.

Daniel Kahn Gillmor: The legal utility of deniability in secure chat

This Monday, I attended a workshop on Multi-party Off the Record Messaging and Deniability hosted by the Calyx Institute. The discussion was a combination of legal and technical people, looking at how the characteristics of this particular technology affect (or do not affect) the law. This is a report-back, since I know other people wanted to attend. I'm not a lawyer, but I develop software to improve communications security, I care about these questions, and I want other people to be aware of the discussion. I hope I did not misrepresent anything below. I'd be happy if anyone wants to offer corrections. BackgroundOff the Record Messaging (OTR) is a way to secure instant messaging (e.g. jabber/XMPP, gChat, AIM). The two most common characteristics people want from a secure instant messaging program are:
Authentication
Each participant should be able to know specifically who the other parties are on the chat.
Confidentiality
The content of the messages should only be intelligible to the parties involved with the chat; it should appear opaque or encrypted to anyone else listening in. Note that confidentiality effectively depends on authentication -- if you don't know who you're talking to, you can't make sensible assertions about confidentiality.
As with many other modern networked encryption schemes, OTR relies on each user maintaining a long-lived "secret key", and publishing a corresponding "public key" for their peers to examine. These keys are critical for providing authentication (and by extension, for confidentiality). But OTR offers several interesting characteristics beyond the common two. Its most commonly cited characteristics are "forward secrecy" and "deniability".
Forward secrecy
Assuming the parties communicating are operating in good faith, forward secrecy offers protection against a special kind of adversary: one who logs the encrypted chat, and subsequently steals either party's long-term secret key. Without forward secrecy, such an adversary would be able to discover the content of the messages, violating the confidentiality characteristic. With forward secrecy, this adversary is be stymied and the messages remain confidential.
Deniability
Deniability only comes into play when one of the parties is no longer operating in good faith (e.g. their computer is compromised, or they are collaborating with an adversary). In this context, if Alice is chatting with Bob, she does not want Bob to be able to cryptographically prove to anyone else that she made any of the specific statements in the conversation. This is the focus of Monday's discussion. To be clear, this kind of deniability means Alice can correctly say "you have no cryptographic proof I said X", but it does not let her assert "here is cryptographic proof that I did not say X" (I can't think of any protocol that offers the latter assertion). The opposite of deniability is a cryptographic proof of origin, which usually runs something like "only someone with access to Alice's secret key could have said X."
The traditional two-party OTR protocol has offered both forward secrecy and deniability for years. But deniability in particular is a challenging characteristic to provide for group chat which is the domain of Multi-Party OTR (mpOTR). You can read some past discussion about the challenges of deniability in mpOTR (and why it's harder when there are more than two people chatting) from the otr-users mailing list. If you're not doing anything wrong... The discussion was well-anchored by a comment from another participant who cheekily asked "If you're not doing anything wrong, why do you need to hide your chat at all, let alone be able to deny it?" The general sense of the room was that we'd all heard this question many times, from many people. There are lots of problems with the ideas behind the question from many perspectives. But just from a legal perspective, there are at least two problems with the way this question is posed: In these situations, people confront real risk from the law. If we care about these people, we need to figure out if we can build systems to help them reduce that legal risk (of course we also need to fix broken laws, and the legal environment in general, but those approaches were out of scope for this discussion). The Legal Utility of Deniability Monday's meeting was called specifically because it wasn't clear how much real-world usefulness there is in the "deniability" characteristic, and whether this feature is worth the development effort and implementation tradeoffs required. In particular, the group was interested in deniability's utility in legal contexts; many (most?) people in the room were lawyers, and it's also not clear that deniability has much utility outside of a formal legal setting. If your adversary isn't constrained by some rule of law, they probably won't care at all whether there is a cryptographic proof or not that you wrote a particular message (In retrospect, one possible exception is exposure in the media, but we did not discuss that scenario). Places of possible usefulness So where might deniability come in handy during civil litigation or a criminal trial? Presumably the circumstance is that a piece of a chat log is offered as incriminating evidence, and the defendant is trying to deny something that they appear to have said in the log. This denial could take place in two rather different contexts: during rules over admissibility of evidence, or (once admitted) in front of a jury. In legal wrangling over admissibility, apparently a lot of horse-trading can go on -- each side concedes some things in exchange for the other side conceding other things. It appears that cryptographic proof of origin (that is, a lack of deniability) on the chat logs themselves might reduce the amount of leverage a defense lawyer can get from conceding or arguing strongly over that piece of evidence. For example, if the chain of custody of a chat transcript is fuzzy (i.e. the transcript could have been mishandled or modified somehow before reaching trial), then a cryptographic proof of origin would make it much harder for the defense to contest the chat transcript on the grounds of tampering. Deniability would give the defense more bargaining power. In arguing about already-admitted evidence before a jury, deniability in this sense seems like a job for expert witnesses, who would need to convince the jury of their interpretation of the data. There was a lot of skepticism in the room over this, both around the possibility of most jurors really understanding what OTR's claim of deniability actually means, and on jurors' ability to distinguish this argument from a bogus argument presented by an opposing expert witness who is willing to lie about the nature of the protocol (or who misunderstands it and passes on their misunderstanding to the jury). The complexity of the tech systems involved in a data-heavy prosecution or civil litigation are themselves opportunities for lawyers to argue (and experts to weigh in) on the general reliability of these systems. Sifting through the quantities of data available and ensuring that the appropriate evidence is actually findable, relevant, and suitably preserved for the jury's inspection is a hard and complicated job, with room for error. OTR's deniability might be one more element in a multi-pronged attack on these data systems. These are the most compelling arguments for the legal utility of deniability that I took away from the discussion. I confess that they don't seem particularly strong to me, though some level of "avoiding a weaker position when horse-trading" resonates with me. What about the arguments against its utility? Limitations The most basic argument against OTR's deniability is that courts don't care about cryptographic proof for digital evidence. People are convicted or lose civil cases based on unsigned electronic communications (e.g. normal e-mail, plain chat logs) all the time. OTR's deniability doesn't provide any legal cover stronger than trying to claim you didn't write a given e-mail that appears to have originated from your account. As someone who understands the forgeability of e-mail, i find this overall situation troubling, but it seems to be where we are. Worse, OTR's deniability doesn't cover whether you had a conversation, just what you said in that conversation. That is, Bob can still cryptographically prove to an adversary (or before a judge or jury) that he had a communication with someone controlling Alice's secret key (which is probably Alice); he just can't prove that Alice herself said any particular part of the conversation he produces. Additionally, there are runtime tradeoffs depending on how the protocol manages to achieve these features. For example, forward secrecy itself requires an additional round trip or two when compared to authenticated, encrypted communications without forward secrecy (a "round trip" is a message from Alice to Bob followed by a message back from Bob to Alice). Getting proper deniability into the mpOTR spec might incur extra latency (imagine having to wait 60 seconds after everyone joins before starting a group chat, or a pause in the chat of 15 seconds when a new member joins) or extra computational power (meaning that they might not work well on slower/older devices) or an order of magnitude more bandwidth (meaning that chat might not work at all on a weak connection). There could also simply be complexity that makes it harder to correctly implement a protocol with deniability than an alternate protocol without deniability. Incorrectly-implemented software can put its users at risk. I don't know enough about the current state of mpOTR to know what the specific tradeoffs are for the deniability feature, but it's clear there will be some. Who decides whether the tradeoffs are worth the feature? Other kinds of deniability Further weakening the case for the legal utility of OTR's deniability, there seem to be other ways to get deniability in a legal context over a chat transcript. There are deniability arguments that can be made from outside the protocol. For example, you can always claim someone else took control of your computer while you were asleep or using the bathroom or eating dinner, or you can claim that your computer had a virus that exported your secret key and it must have been used by someone else. If you're desperate enough to sacrifice your digital identity, you could arrange to have your secret key published, at which point anyone can make signed statements with it. Having forward secrecy makes it possible to expose your secret key without exposing the content of your past communications to any listener who happened to log them. Conclusion My takeaway from the discussion is that the legal utility of OTR's deniability is non-zero, but quite low; and that development energy focused on deniability is probably only justified if there are very few costs associated with it. Several folks pointed out that most communications-security tools are too complicated or inconvenient to use for normal people. If we have limited development energy to spend on securing instant messaging, usability and ubiquity would be a better focus than this form of deniability. Secure chat systems that take too long to make, that are too complex, or that are too cumbersome are not going to be adopted. But this doesn't mean people won't chat at all -- they'll just use cleartext chat, or maybe they'll use supposedly "secure" protocols with even worse properties: for example, without proper end-to-end authentication (permitting spoofing or impersonation by the server operator or potentially by anyone else); with encryption that is reversible by the chatroom operator or flawed enough to be reversed by any listener with a powerful computer; without forward secrecy; or so on. As a demonstration of this, we heard some lawyers in the room admit to using Skype to talk with their clients even though they know it's not a safe communications channel because their clients' adversaries might have access to the skype messaging system itself. My conclusion from the meeting is that there are a few particular situations where deniability could be useful legally, but that overall, it is not where we as a community should be spending our development energy. Perhaps in some future world where all communications are already authenticated, encrypted, and forward-secret by default, we can look into improving our protocols to provide this characteristic, but for now, we really need to work on usability, popularization, and wide deployment. Thanks Many thanks to Nick Merrill for organizing the discussion, to Shayana Kadidal and Stanley Cohen for providing a wealth of legal insight and legal experience, to Tom Ritter for an excellent presentation of the technical details, and to everyone in the group who participated in the interesting and lively discussion.

Jonathan McDowell: Thoughts on SSDs and encryption

My laptop is just over 3 years old, which is about the point I start to think about a replacement. At present there's nothing that's an obvious contender so I've been looking at an SSD to prolong it by another year or two. One of the other thoughts I had is that I currently use dm-crypt under Linux to provide whole disk encryption for everything except the boot partition - I have a bunch of my personal financial and immigration documents stored that I'd prefer not to get disclosed if my laptop is stolen. Modern drives have started offered integral AES encryption options, so perhaps I could offload that to the drive (my i5 470UM lacks the hardware instructions for this). General consensus in the pub (where all the best security advice is to be found) is that no one present trusted SSD firmware authors to not use some badly chosen AES crypto mode, or leave the key lying around plain text in easily readable flash, or some other implementation mishap. So how hard would it be to retrofit reliable (or at least source verifiable and thus more reliable) crypto to an SSD? There was an impressive article recently about reverse engineering the firmware of a HDD, to the point of modifying data returned to the host and also running Linux on the controller. It seems that SSD firmware should be easier - NAND is simpler to talk to than motors and magnetic sensors, right? It's a case of gluing together a SATA interface, a NAND controller and an AES offload engine, yes? Aside from the minor matter of finding a suitable drive with an available JTAG interface, a controller with docs (or more likely that can be reverse engineered) and enough time to produce a replacement open firmware, that is. Alternatively can anyone provide some idea of how secure the available laptop SSDs on the market actually are? I'm fine with "the NSA can read your data if they want" because a determined attacker will be able to find other ways to get my data anyway, but I don't want "anyone who finds the drive can use this loophole in the firmware by wiggling some bits with jtag to dump the key and read all your data".

Russ Allbery: Pod::Thread 1.00 (and spin 1.80)

Well, this wasn't really what I intended to do with the tail end of my vacation, but I got started on it last night after fixing a different bug and failed to stop. Thread is the macro language (converted to HTML by a program called spin) that I use for maintaining all of my web pages, as mentioned in the previous release announcements from this week. Pod::Thread converts POD documentation into thread so that spin can convert it to HTML. This has multiple advantages over converting it directly to HTML for my web site, such as being able to use spin's methods for adding navigation links and not having to come up with separate style sheets. This release finally converts Pod::Thread to use Pod::Simple as the POD parser, which means I no longer have any modules using Pod::Parser. I find Pod::Simple a bit more fiddly to work with, but it's actively maintained and higher-quality. This conversion, for example, fixes a problem with being too aggressive about turning =item into a numeric list, something that I really couldn't fix with Pod::Parser. Also fixed in this release is the bug that got me started down this path: mishandling of URLs with anchor text. This is the second Perl module that I've converted to my new coding style and augmented test suite, and I'm getting a little bit faster at it, but it still took me a full day. (Although that included the Pod::Simple rewrite, which required touching most of the code.) I'm not entirely sure that should have been my top priority today, but oh well, I had to do it sometime. You can get the latest version from my web tools distribution page. I also uploaded a new Debian package to my personal repository. I also released spin 1.80, a follow-on from the previous release, that fixes a bug in the new code to determine last modification date from Git.

Gunnar Wolf: To CURP or not to CURP

To CURP or not to CURP
CURP: Clave nica del Registro Poblacional, or Unique Population Registry Code. This is a (hopefully) unique, 18 character long, string identifying each Mexican - I won't get into the technicalities, but serve yourselves. By following such a convoluted scheme, the authorities should have ensured a biunivocal relation between each person and their CURP number. Well, at some point, due to a bureaucratical mishap completely outside my hands (my patron registered me with the wrong birth date, as you can see in the page at the bottom), I got two CURPs - And the procedure to fix it was far from trivial. Last Sunday, I entered the Consulta CURP system to print a copy of the official document. Much to my surprise... It answered that I was not registered! A couple of minutes later, I tried again, and succeeded. But I could not refrain from printing my Certificate of non-registration. I guess their system follows a strong-but-stupid scheme such as:
  1. begin
  2. db = connect_to_database
  3. curp = find_curp_for_person(query)
  4. generate_document(curp)
  5. rescue
  6. generate_non_reg_certificate(query)
So, right, if a user submits a query during the system maintenance window (after all, it was Sunday after 23:00), the system will fail to connect to the database (or whatever), raise an exception, trap it, and... Well, you no longer exist, thanks for playing!

Axel Beckert: Git Snapshot of GNU Screen in Debian Experimental

I just uploaded a snapshot of GNU Screen to Debian Experimental. The package (4.1.0~20110819git450e8f3-1) is based on upstream s HEAD whose most recent commit currently dates to the 19th of August 2011. While the upload fixes tons of bugs which accumulated over the past two years in Debian s, Ubuntu s and upstream s bug tracker, I don t yet regard it as suitable for the next stable release (and hence for Debian Unstable) since there s one not so nice issue about it: Nevertheless it fixes a lot of open issues (of which the oldest is a wishlist bug report dating back to 1998 :-) and I didn t want to withhold it from the rest of the Debian community so I uploaded it to Debian Experimental. Issues closed in Debian ExperimentalIssues which will be closed in UbuntuPlease test the version from Experimental If you are affected by one of the issues mentioned above, please try the version from Debian Experimental and check if they re resolved for you, too. Thanks to all who contributed! A lot of the fixes have been made or applied upstream by Sadrul Habib Chowdhury who also industriously tagged Debian bug reports as fixed-upstream . Thanks! Thanks also to Brian P Kroth who gave the initial spark to this upload by packaging Fedora 15 s git snapshot for Debian and filing bug although the upload is based on the current HEAD version of GNU Screen as this fixes some more important issues than the snapshot Fedora 15 includes. That way also two patches from Fedora/RedHat s screen package are included in this upload. (Co-) Maintainer wanted! Oh, and if you care about the state of GNU Screen in Debian, I d really appreciate if you d join in and contribute to our collab-maint git repository there are still a lot of issues unresolved and I know that I won t be able to fix all of them myself. And since Hessophanes unfortunately currently has not enough time for the package, we definitely need more people maintaining this package. P.S. Yes, I know about tmux and tried to get some of my setups working with it, too. But I still prefer screen over tmux. :-)

Joey Hess: size of the git sha1 collision attack surface

The kernel.org compromise has people talking about the security of git's use of sha1. Talking about this is a good thing, I think, but there's a lot of smug "we're cryptographically secure" in the air that does not seem warranted coming from non-cryptographers like me. Two years ago I had a discussion on my blog about git and sha1, that reached similar conclusions to what I'm seeing here: It seems that current known sha1 attacks require somehow getting an ugly colliding binary file accepted into the repository in the first place. Hard to manage for peer reviewed source code. We all hate firmware in the kernel, so perhaps this is another reason it's bad. ;-) Etc. Well, not so fast. Git's exposure to sha1 collisions is broader than just files. Git also stores data for commits, and directory trees. Git's tree objects are interesting because they're a bag of bytes that is rarely if ever manually examined. If there was a way to exploit git such that it ignored some trailing garbage at the end of a tree object, then here's an attack injection vector that would be unlikely to be caught by peer review. If you can change the content of a tree without changing its sha1, you can simply make it link to an older version of a file that had an exploitable problem. Or you can assemble a combination of files that results in an new exploitable problem. (For example, suppose a buffer size was hardcoded in two files in the kernel, and then the size was changed in both -- make a tree that contains one change and not the other.) Now, git's tree-walk code, until 2008, mishandled malformed data by accessing memory outside the tree buffer. Was this an exploitable bug in git? I don't know. It is interesting that the fix, in 64cc1c0909949fa2866ad71ad2d1ab7ccaa673d9 relied on the parser stopping at a NULL -- great if you want to put some garbage after the tree's filename. With that said, the particular exploit I describe above probably won't work -- I tried! Here's all the code that stands between us and this exploit:
        if (size < 24   buf[size - 21])
                die("corrupt tree file");
        path = get_mode(buf, &mode);
        if (!path   !*path)
                die("corrupt tree file");
Any good C programmer would recognise that this magic-constant-laden code needs to be careful about the size of the buffer. It's not as clear though, that it needs to be careful about consuming the entire contents of the buffer. And C programmers involved with git have gotten this code wrong before. tldr: If git is a castle, it was built just after cannons were invented, and we've had our fingers in our ears for several years as their power improved. Now the outer wall of sha1 is looking increasingly like one of straw, and we're down to a rather thin inner wall of C code.

Joey Hess: solar day 2

End of the second day in the off-grid house. Three things strike me about being here: quiet, rhythm, and awareness. In the city, I am constantly annoyed by noise. Here, there's a empty, echoing feeling to the quiet. It's not lack of noise exactly -- I can hear cicadas and birds right now -- but it's still quiet. At first I wanted to fill it, but now I can feel my hearing instead expanding outward. Catching a faint engine noise, or a dog barking in the distance. Here there's a rhythm to the day driven by the sun. Get up, connect the batteries to the solar panels. (Only necessary because the charge controller is broken.) Check and record the battery levels, make sure the panels are producing well. Think about adjusting them at solar noon. Check the cooler to see how the ice is holding out. Do weekly chores: Refilling the kerosine lanterns and replacing the rock salt used to control the humidity, which is the downside to a earth-sheltered house that stays 70 degrees cool on a 90 degree day. In the evening, watch the sun go down, disconnect the solar panels, record battery levels, and light lanterns. That's the shape of the day. Besides being aware of distant sounds and time time of day, being here brings to the fore awareness of consumables. Until I get a fridge sorted out, I have a cooler full of ice that I have to monitor. There's propane for the stove, and kerosine for the lanterns. And of course always the state of the batteries. So far, the first battery bank seems likely to last longer than the ice. I'll know better tomorrow. Unfortunatly I burned out the 5v power suppzly I was using to run my NSLU2 in a wiring mishap, so I have to run that on an inverter for now, and the batteries, though not low, can barely power both the inverter and my laptop. This has made staying online tricky. But I'm finding dialup psurpisingly tolerable, and it helps to generally slow down, too. Despite all the above, I got about as much real work done today as I normally would. ?tag lay offgrid

Gustavo Noronha Silva: Google s User-Agent sniffing makes one more victim

Remember when I said Epiphany worked out of the box with Youtube s WebM? Well, Google has recently decided to deny us WebM, like it did before with Wave, the Pacman doodle, and who knows what else? \o/ Wouldn t it be nice if Google practiced what they preach? Update: so it looks like my message went through to the people who needed to see it, and they found a filtering error in the User Agent sniffing code that made it think Epiphany was a too old Safari - I m told the change will land in Youtube soon, thanks for those paying attention, and working on this! User Agent sniffing keeps being a problem, of course, and there are other stuff to fix, so I will probably still push my patch to spoof the user agent to google services which are still mishandling Epiphany, but it s good to see some progress being made! Update2: I started shipping a patch to send the Chrome user agent string to google domains in the Debian package for WebKitGTK+, when the enable-site-specific-quirks setting is enabled (which is the case for Epiphany); I already found something we were missing out on =D Google Images seems to have been greatly improved, and now faking being Chrome we are also able to enjoy it:

Google Images improved
