Utkarsh Gupta: FOSS Activites in May 2021

Here s my (twentieth) monthly update about the activities I ve done in the F/L/OSS world.

Debian
This was my 29th month of actively contributing to Debian. I became a DM in late March 2019 and a DD on Christmas 19! \o/ Interesting month, surprisingly. Lots of things happening and lots of moving parts; becoming the new normal , I believe. Anyhow, working on Ubuntu full-time has its own advantage and one of them is being able to work on Debian stuff! So whilst I couldn t upload a lot of packages because of the freeze, here s what I worked on:

Uploads and bug fixes:

Other $things:
  • Mentoring for newcomers and assisting people in BSP.
  • Moderation of -project mailing list.

Ubuntu
This was my 4th month of actively contributing to Ubuntu. Now that I ve joined Canonical to work on Ubuntu full-time, there s a bunch of things I do! \o/ This month, by all means, was dedicated mostly to PHP 8.0, transitioning from PHP 7.4 to 8.0. Naturally, it had so many moving parts and moments of utmost frustration, shared w/ Bryce. :D So even though I can t upload anything, I worked on the following stuff & asked for sponsorship.
But before, I d like to take a moment to stress how kind and awesome Gianfranco Costamagna, a.k.a. LocutusOfBorg is! He s been sponsoring a bunch of my things & helping with re-triggers, et al. Thanks a bunch, Gianfranco; beers on me whenever we meet!

Debian (E)LTS
Debian Long Term Support (LTS) is a project to extend the lifetime of all Debian stable releases to (at least) 5 years. Debian LTS is not handled by the Debian security team, but by a separate group of volunteers and companies interested in making it a success. And Debian Extended LTS (ELTS) is its sister project, extending support to the Jessie release (+2 years after LTS support). This was my twentieth month as a Debian LTS and eleventh month as a Debian ELTS paid contributor.
I was assigned 29.75 hours for LTS and 40.00 hours for ELTS and worked on the following things:

LTS CVE Fixes and Announcements:

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

Utkarsh Gupta: FOSS Activites in April 2021

Here s my (nineteenth) monthly update about the activities I ve done in the F/L/OSS world.

Debian
This was my 28th month of actively contributing to Debian. I became a DM in late March 2019 and a DD on Christmas 19! \o/ Crazy month, as always. Lots of things happening and lots of moving parts.
Now that I am working on Ubuntu-full time, I barely get much time to do any extra stuff. Then the massive COVID wave that has plunged India had made this month further crazier. More on that later, maybe. IDK. Anyway, I did some Debian stuff, thanks to Salzburg BSP (more down below). I worked on the following stuff:

Uploads and bug fixes:

Other $things:
  • Mentoring for newcomers and assisting people in BSP.
  • Moderation of -project mailing list.

Salzburg BSP 2021 This was my first virtual BSP and the first BSP in Salzburg and it was absolutely amazing!
Many kudos to Bernd Zeimetz for organizing it so smoothly and wonderfully, for real! \o/ We had a bunch of amazing sessions, besides hacking, of course, like:
  • yoga,
  • sports,
  • games, and
  • datacenter tour -> which was super!
We also had lots of things happening at #debian-bsp-2021-szg and did a lot of work.

Debian (E)LTS
Debian Long Term Support (LTS) is a project to extend the lifetime of all Debian stable releases to (at least) 5 years. Debian LTS is not handled by the Debian security team, but by a separate group of volunteers and companies interested in making it a success. And Debian Extended LTS (ELTS) is its sister project, extending support to the Jessie release (+2 years after LTS support). This was my nineteenth month as a Debian LTS and tenth month as a Debian ELTS paid contributor.
I was assigned 60.00 hours for LTS and 60.00 hours for ELTS and worked on the following things:

Petter Reinholdtsen: VLC bittorrent plugin in Bullseye, saved by the bell?

Yesterday morning I got a warning call from the Debian quality control system that the VLC bittorrent plugin was due to be removed because of a release critical bug in one of its dependencies. As you might remember, this plugin make VLC able to stream videos directly from a bittorrent source using both torrent files and magnet links, similar to using a HTTP source. I believe such protocol support is a vital feature in VLC, allowing efficient streaming from sources such at the almost 7 million movies in the Internet Archive. The dependency was the unmaintained libtorrent-rasterbar package, and the bug in question blocked its python library from working properly. As I did not want Bullseye to release without bittorrent support in VLC, I set out to check out the status, and track down a fix for the problem. Luckily the issue had already been identified and fixed upstream, providing everything needed. All I needed to do was to fetch the Debian git repository, extract and trim the patch from upstream and apply it to the Debian package for upload. The fixed library was uploaded yesterday evening. But that is not enough to get it into Bullseye, as Debian is currently in package freeze to prepare for a new next stable release. Only non-critical packages with autopkgtest setup included, in other words able to validate automatically that the package is working, are allowed to migrate automatically into the next release at this stage. And the unmaintained libtorrent-rasterbar lack such testing, and thus needed a manual override. I am happy to report that such manual override was approved a few minutes ago, thus increasing significantly the chance of VLC bittorrent streaming being available out of the box also for Debian/Buster users. A bit too close shave for my liking, as the Bullseye release is most likely just a few days away, and this did feel like the package was saved by the bell. I am so glad the warning email showed up in time for me to handle the issue, and a big thanks go to the Debian Release team for the quick feedback on #debian-release and their swift unblocking.

Michael Prokop: A Ceph war story

It all started with the big bang! We nearly lost 33 of 36 disks on a Proxmox/Ceph Cluster; this is the story of how we recovered them. At the end of 2020, we eventually had a long outstanding maintenance window for taking care of system upgrades at a customer. During this maintenance window, which involved reboots of server systems, the involved Ceph cluster unexpectedly went into a critical state. What was planned to be a few hours of checklist work in the early evening turned out to be an emergency case; let s call it a nightmare (not only because it included a big part of the night). Since we have learned a few things from our post mortem and RCA, it s worth sharing those with others. But first things first, let s step back and clarify what we had to deal with. The system and its upgrade One part of the upgrade included 3 Debian servers (we re calling them server1, server2 and server3 here), running on Proxmox v5 + Debian/stretch with 12 Ceph OSDs each (65.45TB in total), a so-called Proxmox Hyper-Converged Ceph Cluster. First, we went for upgrading the Proxmox v5/stretch system to Proxmox v6/buster, before updating Ceph Luminous v12.2.13 to the latest v14.2 release, supported by Proxmox v6/buster. The Proxmox upgrade included updating corosync from v2 to v3. As part of this upgrade, we had to apply some configuration changes, like adjust ring0 + ring1 address settings and add a mon_host configuration to the Ceph configuration. During the first two servers reboots, we noticed configuration glitches. After fixing those, we went for a reboot of the third server as well. Then we noticed that several Ceph OSDs were unexpectedly down. The NTP service wasn t working as expected after the upgrade. The underlying issue is a race condition of ntp with systemd-timesyncd (see #889290). As a result, we had clock skew problems with Ceph, indicating that the Ceph monitors clocks aren t running in sync (which is essential for proper Ceph operation). We initially assumed that our Ceph OSD failure derived from this clock skew problem, so we took care of it. After yet another round of reboots, to ensure the systems are running all with identical and sane configurations and services, we noticed lots of failing OSDs. This time all but three OSDs (19, 21 and 22) were down:

The same issue was present for the other failing OSDs. We hoped, that the data itself was still there, and only the mounting of the XFS partitions failed. The Ceph cluster was initially installed in 2017 with Ceph jewel/10.2 with the OSDs on filestore (nowadays being a legacy approach to storing objects in Ceph). However, we migrated the disks to bluestore since then (with ceph-disk and not yet via ceph-volume what s being used nowadays). Using ceph-disk introduces these 100MB XFS partitions containing basic metadata for the OSD. Given that we had three working OSDs left, we decided to investigate how to rebuild the failing ones. Some folks on #ceph (thanks T1, ormandj + peetaur!) were kind enough to share how working XFS partitions looked like for them. After creating a backup (via dd), we tried to re-create such an XFS partition on server1. We noticed that even mounting a freshly created XFS partition failed:

Ouch. This very much looked related to the actual issue we re seeing. So we tried to execute mkfs.xfs with a bunch of different sunit/swidth settings. Using -d sunit=512 -d swidth=512 at least worked then, so we decided to force its usage in the creation of our OSD XFS partition. This brought us a working XFS partition. Please note, sunit must not be larger than swidth (more on that later!). Then we reconstructed how to restore all the metadata for the OSD (activate.monmap, active, block_uuid, bluefs, ceph_fsid, fsid, keyring, kv_backend, magic, mkfs_done, ready, require_osd_release, systemd, type, whoami). To identify the UUID, we can read the data from ceph --format json osd dump , like this for all our OSDs (Zsh syntax ftw!): 
synpromika@server1 ~ % for f in  0..37  ; printf "osd-$f: %s\n" "$(sudo ceph --format json osd dump   jq -r ".osds[]   select(.osd==$f)   .uuid")"
osd-0: 4568c300-ad83-4288-963e-badcd99bf54f
osd-1: e573a17a-ccde-4719-bdf8-eef66903ca4f
osd-2: 0e1b2626-f248-4e7d-9950-f1a46644754e
osd-3: 1ac6a0a2-20ee-4ed8-9f76-d24e900c800c
[...]
Identifying the corresponding raw device for each OSD UUID is possible via: 
synpromika@server1 ~ % UUID="4568c300-ad83-4288-963e-badcd99bf54f"
synpromika@server1 ~ % readlink -f /dev/disk/by-partuuid/"$ UUID "
/dev/sdc1
The OSD s key ID can be retrieved via: 
synpromika@server1 ~ % OSD_ID=0
synpromika@server1 ~ % sudo ceph auth get osd."$ OSD_ID " -f json 2>/dev/null   jq -r '.[]   .key'
AQCKFpZdm0We[...]
Now we also need to identify the underlying block device: 
synpromika@server1 ~ % OSD_ID=0
synpromika@server1 ~ % sudo ceph osd metadata osd."$ OSD_ID " -f json   jq -r '.bluestore_bdev_partition_path'    
/dev/sdc2
With all of this, we reconstructed the keyring, fsid, whoami, block + block_uuid files. All the other files inside the XFS metadata partition are identical on each OSD. So after placing and adjusting the corresponding metadata on the XFS partition for Ceph usage, we got a working OSD hurray! Since we had to fix yet another 32 OSDs, we decided to automate this XFS partitioning and metadata recovery procedure. We had a network share available on /srv/backup for storing backups of existing partition data. On each server, we tested the procedure with one single OSD before iterating over the list of remaining failing OSDs. We started with a shell script on server1, then adjusted the script for server2 and server3. This is the script, as we executed it on the 3rd server. Thanks to this, we managed to get the Ceph cluster up and running again. We didn t want to continue with the Ceph upgrade itself during the night though, as we wanted to know exactly what was going on and why the system behaved like that. Time for RCA! Root Cause Analysis So all but three OSDs on server2 failed, and the problem seems to be related to XFS. Therefore, our starting point for the RCA was, to identify what was different on server2, as compared to server1 + server3. My initial assumption was that this was related to some firmware issues with the involved controller (and as it turned out later, I was right!). The disks were attached as JBOD devices to a ServeRAID M5210 controller (with a stripe size of 512). Firmware state: 
synpromika@server1 ~ % sudo storcli64 /c0 show all   grep '^Firmware'
Firmware Package Build = 24.16.0-0092
Firmware Version = 4.660.00-8156
synpromika@server2 ~ % sudo storcli64 /c0 show all   grep '^Firmware'
Firmware Package Build = 24.21.0-0112
Firmware Version = 4.680.00-8489
synpromika@server3 ~ % sudo storcli64 /c0 show all   grep '^Firmware'
Firmware Package Build = 24.16.0-0092
Firmware Version = 4.660.00-8156
This looked very promising, as server2 indeed runs with a different firmware version on the controller. But how so? Well, the motherboard of server2 got replaced by a Lenovo/IBM technician in January 2020, as we had a failing memory slot during a memory upgrade. As part of this procedure, the Lenovo/IBM technician installed the latest firmware versions. According to our documentation, some OSDs were rebuilt (due to the filestore->bluestore migration) in March and April 2020. It turned out that precisely those OSDs were the ones that survived the upgrade. So the surviving drives were created with a different firmware version running on the involved controller. All the other OSDs were created with an older controller firmware. But what difference does this make? Now let s check firmware changelogs. For the 24.21.0-0097 release we found this: 
- Cannot create or mount xfs filesystem using xfsprogs 4.19.x kernel 4.20(SCGCQ02027889)
- xfs_info command run on an XFS file system created on a VD of strip size 1M shows sunit and swidth as 0(SCGCQ02056038)
Our XFS problem certainly was related to the controller s firmware. We also recalled that our monitoring system reported different sunit settings for the OSDs that were rebuilt in March and April. For example, OSD 21 was recreated and got different sunit settings: 
WARN  server2.example.org  Mount options of /var/lib/ceph/osd/ceph-21      WARN - Missing: sunit=1024, Exceeding: sunit=512
We compared the new OSD 21 with an existing one (OSD 25 on server3): 
synpromika@server2 ~ % systemctl show var-lib-ceph-osd-ceph\\x2d21.mount   grep sunit
Options=rw,noatime,attr2,inode64,sunit=512,swidth=512,noquota
synpromika@server3 ~ % systemctl show var-lib-ceph-osd-ceph\\x2d25.mount   grep sunit
Options=rw,noatime,attr2,inode64,sunit=1024,swidth=512,noquota
Thanks to our documentation, we could compare execution logs of their creation:

So back then, we even tried to track this down but couldn t make sense of it yet. But now this sounds very much like it is related to the problem we saw with this Ceph/XFS failure. We follow Occam s razor, assuming the simplest explanation is usually the right one, so let s check the disk properties and see what differs: 
synpromika@server1 ~ % sudo blockdev --getsz --getsize64 --getss --getpbsz --getiomin --getioopt /dev/sdk
4685545472
2398999281664
512
4096
524288
262144
synpromika@server2 ~ % sudo blockdev --getsz --getsize64 --getss --getpbsz --getiomin --getioopt /dev/sdk
4685545472
2398999281664
512
4096
262144
262144
See the difference between server1 and server2 for identical disks? The getiomin option now reports something different for them: 
synpromika@server1 ~ % sudo blockdev --getiomin /dev/sdk            
524288
synpromika@server1 ~ % cat /sys/block/sdk/queue/minimum_io_size
524288
synpromika@server2 ~ % sudo blockdev --getiomin /dev/sdk 
262144
synpromika@server2 ~ % cat /sys/block/sdk/queue/minimum_io_size
262144
It doesn t make sense that the minimum I/O size (iomin, AKA BLKIOMIN) is bigger than the optimal I/O size (ioopt, AKA BLKIOOPT). This leads us to Bug 202127 cannot mount or create xfs on a 597T device, which matches our findings here. But why did this XFS partition work in the past and fails now with the newer kernel version? The XFS behaviour change Now given that we have backups of all the XFS partition, we wanted to track down, a) when this XFS behaviour was introduced, and b) whether, and if so how it would be possible to reuse the XFS partition without having to rebuild it from scratch (e.g. if you would have no working Ceph OSD or backups left). Let s look at such a failing XFS partition with the Grml live system:

    xfs: catch bad stripe alignment configurations
    
    When stripe alignments are invalid, data alignment algorithms in the
    allocator may not work correctly. Ensure we catch superblocks with
    invalid stripe alignment setups at mount time. These data alignment
    mismatches are now detected at mount time like this:

root@grml-2017-05 ~ # mount -t xfs -o sunit=512,swidth=512 ./sdd1.dd /mnt/
root@grml-2017-05 ~ # umount /mnt/
And indeed, mounting this rewritten filesystem then also works with newer kernels: 
root@grml-2020-06 ~ # mount ./sdd1.rewritten /mnt/
root@grml-2020-06 ~ # xfs_info /root/sdd1.rewritten

         =                       crc=1        finobt=1, sparse=0, rmapbt=0

         =                       sunit=64    swidth=64 blks

realtime =none                   extsz=4096   blocks=0, rtextents=0
root@grml-2020-06 ~ # mount -t xfs                
/root/sdd1.rewritten on /mnt type xfs (rw,relatime,attr2,inode64,logbufs=8,logbsize=32k,sunit=512,swidth=512,noquota)
FTR: The sunit=512,swidth=512 from the xfs mount option is identical to xfs_info s output sunit=64,swidth=64 (because mount.xfs s sunit value is given in 512-byte block units, see man 5 xfs, and the xfs_info output reported here is in blocks with a block size (bsize) of 4096, so sunit = 512*512 := 64*4096 ). mkfs uses minimum and optimal sizes for stripe unit and stripe width; you can check this e.g. via (note that server2 with fixed firmware version reports proper values, whereas server3 with broken controller firmware reports non-sense): 
synpromika@server2 ~ % for i in /sys/block/sd*/queue/ ; do printf "%s: %s %s\n" "$i" "$(cat "$i"/minimum_io_size)" "$(cat "$i"/optimal_io_size)" ; done

This is the underlying reason why the initially created XFS partitions were created with incorrect sunit/swidth settings. The broken firmware of server1 and server3 was the cause of the incorrect settings they were ignored by old(er) xfs/kernel versions, but treated as an error by new ones. Make sure to also read the XFS FAQ regarding How to calculate the correct sunit,swidth values for optimal performance . We also stumbled upon two interesting reads in RedHat s knowledge base: 5075561 + 2150101 (requires an active subscription, though) and #1835947. Am I affected? How to work around it? To check whether your XFS mount points are affected by this issue, the following command line should be useful: 
awk '$3 == "xfs" print $2 ' /proc/self/mounts   while read mount ; do echo -n "$mount " ; xfs_info $mount   awk '$0 ~ "swidth" gsub(/.*=/,"",$2); gsub(/.*=/,"",$3); print $2,$3 '   awk '  if ($1 > $2) print "impacted"; else print "OK" ' ; done
If you run into the above situation, the only known solution to get your original XFS partition working again, is to boot into an older kernel version again (4.17 or older), mount the XFS partition with correct sunit/swidth settings and then boot back into your new system (kernel version wise).

Utkarsh Gupta: FOSS Activites in March 2021

Here s my (eighteenth) monthly update about the activities I ve done in the F/L/OSS world.

Debian
This was my 27th month of active contributing to Debian. I became a DM in late March 2019 and a DD on Christmas 19! \o/ This month was a bit exhausting; lots of moving parts. With the financial year ending, it was even more crazy, with me running around to banks, CA, et al.

Uploads and bug fixes:

Other $things:
  • Attended the Debian LTS team meeting.
  • Mentoring for newcomers.
  • Moderation of -project mailing list.

Debian (E)LTS
Debian Long Term Support (LTS) is a project to extend the lifetime of all Debian stable releases to (at least) 5 years. Debian LTS is not handled by the Debian security team, but by a separate group of volunteers and companies interested in making it a success. And Debian Extended LTS (ELTS) is its sister project, extending support to the Jessie release (+2 years after LTS support).

Ryan Kavanagh: Static Comments in Hugo

I switched from Jekyll to Hugo last week for a variety of reasons. One thing that was missing was a port of the jekyll-static-comments plugin that I used to use. I liked it because it saved readers from being tracked by Disqus or other comments solutions, and it required no javascript. To comment, users would email me their comment following a template attached to the bottom of each post. I then piped their email through a script to add it to the right post. As an added benefit, I could delegate comment spam detection to my mail server. I ve managed to reimplement this setup using Hugo. For those who are interested in a similar setup, here is what you need to do.

Pages with comments Instead of being single files, pages need to be leaf bundles. For example, this means that your blog post must be located at /content/blog/2021-03-12-static-comments-in-hugo/index.md instead of /content/blog/2021-03-12-static-comments-in-hugo.md. This lets you store the comments as page resources in the subdirectory /content/blog/2021-03-12-static-comments-in-hugo/comments/.

Partials You should create a comments.html partial and include it in the layout for the pages which should get comments: 
<div class="post-comments">
  <p class="comment-notice"><b>Comments</b>: To comment on this post,
	send me an email following the template below. Your email address
	will not be posted, unless you choose to include it in
	the <span style="font-family: monospace;">link:</span> field.</p>
  <pre class="comment-notice">
To: Your Name &lt;your.email<span>@</span>example.org&gt;
Subject: [blog-comment]   .Page.RelPermalink  
post_id:   .Page.RelPermalink  
author: [How should you be identified? Usually your name or "Anonymous"]
link: [optional link to your website]
Your comments here. Markdown syntax accepted.</pre>
    $scratch := newScratch  
    $scratch.Set "comments" (.Resources.Match "comments/*yml")  
    if eq 1 (len ($scratch.Get "comments"))  
  <h2>1 Comment</h2>
    else  
  <h2>  len ($scratch.Get "comments")   Comments</h2>
    end  
    range ($scratch.Get "comments")  
  <div class="post-comment  % cycle 'odd', 'even' % ">
	  $comment := (.Content   transform.Unmarshal)  
	<span class="post-meta">
		 - $comment.date   dateFormat "Jan 2, 2006 at 15:04" - 
	</span>
	<h3 class="comment-header">
	    if $comment.link  
	  <a href="  $comment.link  ">  $comment.author  </a>
	    else  
	    $comment.author  
	    end  
	  <br />
	</h3>
	  $comment.comment   markdownify  
  </div>
    end  
</div>

Comments To associate comments received by email to posts, I pipe them from mutt (using the keybinding) to the following (admittedly janky) shell script. It takes the comment, reformats it appropriately, and puts it in the post s comments subdirectory. Note that it determines which filename to use based on the email s contents, so make sure to check that the email doesn t contain anything nefarious before you pipe it into the script!

Thorsten Alteholz: My Debian Activities in February 2021

FTP master This month I accepted 162 and rejected 28 packages, which is again a small increase compared to last month. The overall number of packages that got accepted was 291. Debian LTS This was my eightieth month that I did some work for the Debian LTS initiative, started by Raphael Hertzog at Freexian. This month my all in all workload has been 30h. During that time I did LTS and normal security uploads of: I also prepared debdiffs for golang-github-appc-cni, wpa and libbsd, which for one reason or another did not result in a DLA yet. Moreover I did some NEW processing and other stuff on security-master. Last but not least I did some days of frontdesk duties. Debian ELTS This month was the thirty-second ELTS month. During my allocated time I uploaded: Last but not least I did some days of frontdesk duties. Other stuff This month I uploaded new upstream versions of:

Shirish Agarwal: Making life difficult

Freedom house puts India in partly free Just couple of days ago, freedom house published its 2020 rankings for all countries including India. While freedom house shared how democracy in the world has weakened, India chose to take offense about it being called partly free .
India, leader in Internet shutdowns Access Now (copyright)
The above illustration is shared by accessnow . The next big ones who have Internet shutdowns are Yemen 6 and Ethiopia 4. Such internet shutdowns have and will have sad repercussions as would share in another story as well.

Color-coding journalists A story was broken by caravan magazine yesterday and which was followed by newslaundry which shows how the Govt. is looking to just drive some narrative, does not matter whether it s true or false, it should just show that the Govt. is right and others are all wrong. As can be seen, almost all reporters barring a few have kept silent rather than refuting statements attributed to them or happenings which didn t happen. And this goes to a much larger narrative and disinformation route taken by the Govt. which doesn t have any semblance to the truth or reality as people know it. I would illustrate couple of examples below which shares that. In all my young and even adult-life I hadn t seen a Govt. this much against its own people.

Omega Seiki puts a manufacturing plant in Bangladesh Now Omega Seiki is an Indian vendor who chose or had to go to manufacture their electric vehicles in Bangladesh. Now while this is a slightly old story this was broken on social media recently. Everybody starting blaming both the vendor and saying we should break FTA (Free Trade Agreement) with Bangladesh, not knowing that despite the FTA, India has put tariff barriers between India and Bangladesh. I had to share research from Brookings to show where India has been losing. Of course, those who don t want to see, wouldn t see anything wrong in the picture.

Teen raped, asked to marry the accused when she turns 18 Now you may see the above headlines and feel it is ridiculous, but the fact is that these orders were put or given by Madras High Court couple of months back. This was then reported by both Livelaw and BarandBench respectively. Now to be truthful, this news didn t make much noise as it should have, probably as I had shared previously that the Govt. wants to lower the marriageable age to 15 or even less. And this is despite all the medical evidence on the contrary, because it assuages this Govt s masculinity. There is also the very recent case where the SC CJI asked the rapist if he is willing to marry a girl who was underage when she reaches maturity. Another one in which it seems martial rape is not a crime according to the CJI. So it seems these are the state of things in which India finds itself today. There are judges like Vrinda Grover who do question CJI but they are few and there are costs to them who ask questions. Although, as shared this news was overtaken by other news and would have remained so, if not one of the leaders of the present Govt. , a Ramesh Jarkiholi, who hails from Belagavi region of north Karnataka was caught in a sex CD scandal basically asking sexual favors for a permanent Govt. job. He had made statements after the Madras High Court case applauding the judgement given by the judge. While, due to public pressure he had to resign, but not before stating that he had everybody blue films including the Chief Minister of the State. And sad to report that six Karnataka Ministers rushed today or rather yesterday to put a petition in the civil court to restrain media from airing/printing/publishing any defamatory content against them. The court has granted a media gag against 68 media houses for the same. Sadly, the recent happening only reinforce what has been happening in Karnataka since a decade. Update 07/03/2021 Seems yesterday another 10 odd ministers rushed to get the same order. Seems different laws apply to politicians vis-a-vis others. A recent example of Rhea Chakravarthy, an actress and girlfriend of Sushant Singh who was hounded in his suicide case and many accusations made on TV but no evidence till date. From what we know as facts, Sushant committed suicide as he was not getting work due to cronyism in Bollywood. In fact, those who were behind it have white-washed themselves, deleted their tweets etc. and while the public knows, no accountability on them. In fact, there is and was so much that I wanted to share as to what has been happening to women, sadly and thankfully arre did the needful for me. They wrote an entire article which tells what the situation for women in India today is. And if you are wondering why I said, that is because when a site which was made exclusively for people to laugh and have a good time and get relief, when they start writing serious articles, you can be sure that things have gone horribly wrong

Asking Tesla to come to India and at the same time ambivalent on battery Recently, Mr. Nitin Gadkari, a prominent minister of the present Govt. invited Tesla and gave all sorts of incentives to start a manufacturing plant here in India. And while it seems that Tesla has accepted, looking at the Vodafone case, hopefully Tesla does make such contracts where if something goes wrong and they need to sue the Govt. they can do it in States or elsewhere. The way the Govt. acted in the Vodafone case had been a dampener to any MNC investments so far. Although to be fair to both Tesla and GOI, the basic models even if they are manufactured in India will go to less than 1% of the population. The cheapest Tesla Model Y which retails in the U.S. for USD 40k would be around INR 30 lakh. And this is their cheapest car to date. I do know there are rumors of the 25k but that is probably 2-3 years away as shared by Tesla China President Tom Zhu in an interview shared on YT.

https://www.youtube.com/watch?v=aH5leMWFBxI There are couple of interesting comments being made. The fact that China is going to fully open its automobile market to western companies shows how confident China feels about their own vendors. And I m not much impressed about Tesla as I am about the tiny car revolution happening in China. India, if it wanted to, could learn many lessons from China. Even the electric buses they had started in 2010 itself where people in our auto industry thought it was all a fad. Sadly, we are missing most of the technology and if and by the time Tesla starts a production line, dunno where we could get our lithium. India hasn t been as aggressive as other countries when it comes to securing raw natural resources in other countries, as some other countries have. Even besides that, it has been tough when you have so many people who still believe that ICE vehicles (Internal Combustion Engines) are better than EV s and even if they know they choose to believe the propaganda. Couple of months ago a young UK girl who had died due to asthma, an inquest found that air pollution was a factor. The girl s name was Ella Adoo-Kissi-Debrah. This is the first case where the doctor ruled air pollution as a chief factor in a person s death. Probably first of its kind of ruling anywhere in the world. I also shared TCO studies between BEV and ICE vehicles done by people who are considering an electric vehicle but those studies seem to fall on deaf ears.

Starlink This is another of Elon Musk s ventures and would be a money spinner for sure in around the globe. While Starlink has asked TRAI for permission, I don t think they will get it. There is also Bharti Global s Oneweb which probably has a better chance of getting permissions. The reason is censorship. As shared above, India is now a leader in Internet shutdowns and do see this trend only accelerate rather than go the other way around. For people who don t remember, remember how satellite phones were made illegal even though only businessmen could afford it. And this was just 5 years ago. As shared Oneweb would have better shot as they would accept all Government directives without a second thought. Unless Starlink gives a binding to the Govt. to be a willing partner when it wants to have internet shutdowns, it will not work. Now how Elon approaches that is to be seen and known. FWIW, you can t access Starlink webpage on BSNL broadband. My broadband provider gives at the most 300 kbps and sometimes, at late nights or early mornings, around 500 kbps.

Farmer Protests
Lastly, farmer protests have entered 100 days. In the interim, Vivek Kaul, an economist took stock of the Bihar APMC to see if things have really worked as the Govt. supporters were telling. The investigation and the results didn t inspire the confidence as the Govt. said. The sad part is though, that nowadays nobody, at least those in power as well as those who are supporters are keen to read, understand and even argue otherwise. They are all happy with whatsapp knowledge. Till date 200+ people have died in the farmer protests. All mainstream media houses have stopped talking about farmers in the hope that they will disappear. At the end of the day the Govt. wants that the corporates should win at whatever the cost.

Utkarsh Gupta: FOSS Activites in February 2021

Here s my (seventeenth) monthly update about the activities I ve done in the F/L/OSS world.

Debian
This was my 26th month of active contributing to Debian. I became a DM in late March 2019 and a DD on Christmas 19! \o/ This month was a nice mix of amusement, excitement, nervousness, and craziness. More on it below.
Anyway, whilst I was super-insanely busy this month, I still did some Debian stuff here and there. Here are the following things I worked on:

Uploads and bug fixes:

Other $things:
  • Attended the Debian LTS team meeting.
  • Mentoring for newcomers.
  • Moderation of -project mailing list.
  • Sponsored ruby-rspec-stubbed-env for C dric Boutillier, heh :P

Interesting Bits!
  • Last month, I wrote:
    Besides, there s something more that is in the pipelines. Can t talk about it now, shh. But hopefully very sooooooon!
    And now I can talk about it! So here it is..
    I ve joined Canonical as a SDE to work on Ubuntu, full time!!! \o/
    Fully remote + dream job/work + most of the work is in the open-source domain + the beessstttt co-workers one could ever ask for! It s been an amazing time so far and I ll talk more about it later this month.
    But for now, here s our team monitor selfie (with Rick missing because of his secret plan ! )

    We ll soon e-meet them in a more detailed manner in the next blog post, that is, later this month!
  • In another exciting news, I got 2 more CVEs assigned!!! \o/
    No, it is not something that I found, it was discovered by Tavis Ormandy. I just assigned them a CVE ID, CVE-2021-26937 for screen and CVE-2021-27135 for xterm.
    This is my 2nd and 3rd, so I am (still) very excited about this! ^_^

Debian (E)LTS
Debian Long Term Support (LTS) is a project to extend the lifetime of all Debian stable releases to (at least) 5 years. Debian LTS is not handled by the Debian security team, but by a separate group of volunteers and companies interested in making it a success. And Debian Extended LTS (ELTS) is its sister project, extending support to the Jessie release (+2 years after LTS support). This was my sixteenth month as a Debian LTS and seventh month as a Debian ELTS paid contributor.
I was assigned 60.00 hours for LTS and 60.00 hours for ELTS and worked on the following things:

John Goerzen: Recovering Our Lost Free Will Online: Tools and Techniques That Are Available Now

As I ve been thinking and writing about privacy and decentralization lately, I had a conversation with a colleague this week, and he commented about how loss of privacy is related to loss of agency: that is, loss of our ability to make our own choices, pursue our own interests, and be master of our own attention. In terms of telecommunications, we have never really been free, though in terms of Internet and its predecessors, there have been times where we had a lot more choice. Many are too young to remember this, and for others, that era is a distant memory. The irony is that our present moment is one of enormous consolidation of power, and yet also one of a proliferation of technologies that let us wrest back some of that power. In this post, I hope to enlighten or remind us of some of the choices we have lost and also talk about the ways in which we can choose to regain them, already, right now. I will talk about the possibilities, the big dreams that are possible now, and then go into more detail about the solutions. The Problems & Possibilities The limitations of online We make the assumption that we must be online to exchange data. This is reinforced by many modern protocols; Twitter clients, for instance, don t tend to let you make posts by relaying them through disconnected devices. What would it be like if you could fully participate in global communities without a constant Internet connection? If you could share photos with your friends, read the news, read your email, etc. even if you don t have a connection at present? Even if the device you use to do that never has a connection, but can route messages via other devices that do? Would it surprise you to learn that this was once the case? Back in the days of UUCP, much email and Usenet news a global discussion forum that didn t require an Internet connection was relayed via occasional calls over phone lines. This technology remains with us, and has even improved. Sadly, many modern protocols make no effort in this regard. Some email clients will let you compose messages offline to send when you get online later, but the assumption always is that you will be connected to an IP network again soon. NNCP, on the other hand, lets you relay messages over TCP, a radio, a satellite, or a USB stick. Email and Usenet, since they were designed in an era where store-and-forward was valued, can actually still be used in an entirely offline fashion (without ever touching an IP-based network). All it takes is for someone to care to make it happen. You can even still do it over UUCP if you like. The physical and data link layers Many of us just accept that we communicate in a few ways: Wifi for short distances, and then cable modems or DSL for our local Internet connection, and then many people are fuzzy about what happens after that. Or, alternatively, we have 4G phones that are the local Internet connection, and the same fuzzy things happen after. Think about this for a moment. Which of these do you control in any way? Sometimes just wifi, sometimes maybe you have choices of local Internet providers. After that, your traffic is handled by enormous infrastructure companies. There is choice here. People in ham radio have been communicating digitally over long distances without the support of the traditional Internet for decades, but the technology to do this is now more accessible to anyone. Long-distance radio has had tremendous innovation in the last decade; cheap radios can now communicate over several miles/km without any other infrastructure at all. We all carry around radios (Wifi and Bluetooth) in our pockets that don t have to be used as mere access points to the Internet or as drivers of headphones, but can also form their own networks directly (Briar). Meshtastic is an example; it s an instant messenger that can form a mesh over many miles/km and requires no IP infrastructure at all. Briar is similar. XBee radios form a mesh in hardware, allowing peers to reach each other (also over many miles/km) with a serial or framed protocol. Loss of peer-to-peer Back in the late 90s, I worked at a university. I had a 386 on my desk for a workstation not a powerful computer even then. But I put the boa webserver on it and could just serve pages on the Internet. I didn t have to get permission. Didn t have to pay a hosting provider. I could just DO it. And of course that is because the university had no firewall and no NAT. Every PC at the university was a full participant on the Internet as much as the servers at Microsoft or DEC. All I needed was a DNS entry. I could run my own SMTP server if I wanted, run a web or Gopher server, and that was that. There are many reasons why this changed. Nowadays most residential ISPs will block SMTP for their customers, and if they didn t, others would; large email providers have decided not to federate with IPs in residential address spaces. Most people have difficulty even getting a static IP address in the first place. Many are behind firewalls, NATs, or both, meaning that incoming connections of any kind are problematic. Do you see what that means? It has weakened the whole point of the Internet being a network of peers. While IP still acts that way, as a practical matter, there are clients that are prevented from being servers by administrative policy they have no control over. Imagine if you, a person with an Internet connection to your laptop or phone, could just decide to host a website, or a forum on it. For moderate levels of load, they are certainly capable of this. The only thing in the way is the network management policies you can t control. Elaborate technologies exist to try to bridge this divide, and some, like Tor or cjdns, can work quite well. More on this below. Expense of running something popular Related to the loss of peer-to-peer infrastructure is the very high cost of hosting something popular. Do you want to share videos with lots of people? That almost certainly is going to require expensive equipment and bandwidth. There is a reason that there are only a small handful of popular video streaming sites online. It requires a ton of money to host videos at scale. What if it didn t? What if you could achieve economies of scale so much that you, an individual, could compete with the likes of YouTube? You wouldn t necessarily have to run ads to support the service. You wouldn t have to have billions of dollars or billions of viewers just to make it work. This technology exists right now. Of course many of you are aware of how Bittorrent leverages the swarm for files. But projects like IPFS, Dat, and Peertube have taken this many steps further to integrate it into a global ecosystem. And, at least in the case of Peertube, this is a thing that works right now in any browser already! Application-level walled gardens I was recently startled at how much excitement there was when Github introduced dark mode . Yes, Github now offers two colors on its interface. Already back in the 80s and 90s, many DOS programs had more options than that. Git is a decentralized protocol, but Github has managed to make it centralized. Email is a decentralized protocol pick your own provider, and they all communicate but Facebook and Twitter aren t. You can t just pick your provider for Facebook. It s Facebook or nothing. There is a profit motive in locking others out; these networks want to keep you using their platforms because their real customers are advertisers, and they want to keep showing you ads. Is it possible to have a world where you get to pick your own app for sharing photos, and it works even if your parents use a different one? Yes, yes it is. Mastodon and the Fediverse are fantastic examples for social media. Pixelfed is specifically designed for photos, Mastodon for short-form communication, there s Pleroma for more long-form communication, and they all work together. You can use Mastodon to read Pleroma content or look at Pixelfed photos, and there are many (free) providers of each. Freedom from manipulation I recently wrote about the dangers of the attention economy, so I won t go into a lot of detail here. Fundamentally, you are not the customer of Facebook or Google; advertisers are. They optimize their site to keep you on it as much as possible so that they can show you as many ads as possible which makes them as much money as possible. Ads, of course, are fundamentally seeking to manipulate your behavior ( buy this product ). By lowering the cost of running services, we can give a huge boost to hobbyists and nonprofits that want to do so without an ultimate profit motive. For-profit companies benefit also, with a dramatically reduced cost structure that frees them to pursue their mission instead of so many ads. Freedom from snooping (privacy and anonymity) These days, it s not just government snooping that people think about. It s data stolen by malware, spies at corporations (whether human or algorithmic), and even things like basic privacy of one s own security footage. Here the picture is improving; encryption in transit, at least at a basic level, has become much more common with TLS being a standard these days. Sadly, end-to-end encryption (E2EE) is not nearly as much, perhaps because corporations have a profit motive to have access to your plaintext and metadata. Closely related to privacy is anonymity: that is, being able to do things in an anonymous fashion. The two are not necessarily equal: you could send an encrypted message but reveal who the correspondents are, as with email; or, you could send a plaintext message over a Tor exit node that hides who the correspondents are. It is sometimes difficult to achieve both. Nevertheless, numerous answers exist here that tackle one or both problems, from the Signal messenger to Tor. Solutions That Exist Today Let s dive in to some of the things that exist today. One concept you ll see in many of these is integrated encryption with public keys used for addressing. In other words, your public key is akin to an IP address (and in some cases, is literally your IP address.) Data link and networking technologies (some including P2P) P2P Infrastructure While some of the technologies above, such as cjdns, explicitly facitilitate peer-to-peer communication, there are some other application-level technologies to look at. Instant Messengers and Chat I won t go into a lot of detail here since I recently wrote a roundup of secure mesh messengers and also a followup article about Signal and some hidden drawbacks of P2P. Please refer to those articles for some interesting things that are happening in this space. Matrix is a distributed IM platform similar in concept to Slack or IRC, but globally distributed in a mesh. It supports optional E2EE. Social Media I wrote recently about how to join the Fediverse, which covered joining Mastodon, a federeated, decentralized social network. Mastodon is the largest of these, with several million users, and is something of a much nicer version of Twitter. Mastodon is also part of what is known as the Fediverse , which are applications that are loosely joined together by their support of the ActivityPub protocol. Other popular Fediverse applications include Pixelfed (similar to Instagram) and Peertube for sharing video. Peertube is particularly interesting in that it supports Webtorrent for efficiently distributing popular videos. Webtorrent is akin to Bittorrent running efficiently inside your browser. Concluding Remarks Part of my goal with this is encouraging people to dream big, to ask questions like: What could you do if offline were easy? What is possible if you have freedom in the physical and data link layers? Dream big. We re so used to thinking that it s quite difficult for two devices on the Internet to talk to each other. What would be possible if this were actually quite easy? The assumption that costs rise dramatically as popularity increases is also baked into our thought processes. What if that weren t the case could you take on Youtube from your garage? Would lowering barriers to entry lower the ad economy and let nonprofits have more equal footing with large corporations? We have so many walled gardens, from Github to Facebook, that we almost forget it doesn t have to be that way. So having asked these questions, my secondary point is to suggest that these aren t pie-in-the-sky notions. These possibilites are with us right now. You ll notice from this list that virtually every one of these technologies is ad-free at its heart (though some would be capable of serving ads). They give you back your attention. Many preserve privacy, anonymity, or both. Many dramatically improve your freedom of association and communication. Technologies like IPFS and Bittorrent ease the burden of running something popular. Some are quite easy to use (Mastodon or Peertube) while others are much more complex (libp2p or the lower-level mesh network systems). Clearly there is still room for improvement in many areas. But my fundamental point is this: good technology is here, right now. Technical people can vote with their feet and wallets and start using it. Early adopters will help guide the way for the next set of improvements. Join us!

Utkarsh Gupta: FOSS Activites in January 2021

Here s my (sixteenth) monthly update about the activities I ve done in the F/L/OSS world.

Debian
This was my 25th month of contributing to Debian. I became a DM in late March 2019 and a DD on Christmas 19! \o/ This month was bat-shit crazy. Why? We ll come to it later, probably 15th of this month?
Anyway, besides being crazy, hectic, adventerous, and the first of 2021, this month I was super-insanely busy. With what? Hm, more about this later this month! ^_^ However, I still did some Debian stuff here and there. Here are the following things I worked on:

Uploads and bug fixes:

Other $things:
  • Attended the Debian Ruby team meeting.
  • Mentoring for newcomers.
  • Moderation of -project mailing list.
  • Sponsored golang-github-gorilla-css for Fedrico.

Debian (E)LTS
Debian Long Term Support (LTS) is a project to extend the lifetime of all Debian stable releases to (at least) 5 years. Debian LTS is not handled by the Debian security team, but by a separate group of volunteers and companies interested in making it a success. And Debian Extended LTS (ELTS) is its sister project, extending support to the Jessie release (+2 years after LTS support). This was my sixteenth month as a Debian LTS and seventh month as a Debian ELTS paid contributor.
I was assigned 26.00 hours for LTS and 36.75 hours for ELTS and worked on the following things:
(however, I worked extra for 9 hours for LTS and 9 hours for ELTS this month, which I intend to balance from the next month!)

  • General discussion on LTS private and public mailing list.

Interesting Bits!
  • This January, on 23rd and 24th, we had Mini DebConf India 2021 online.
    I had a talk as well, titled, Why Point Releases are important and how you can help prepare them?". It was a fun and a very short talk, where I just list out the reasons and ways to help in the preparation of point releases . I did some experimentation with this talk, figuring out what works for the audience and what doesn t and where can I improve for the next time I talk about this topic! \o/
    You can listen to the talk here and let me know if you have any feedback! Anyway, the conference lasted for 2 days and I also did some volunteering (talk director, talk miester) in Hindi and English, both! It was all so fun and new. Anyway, here s the picture we took:
  • In another exciting news, I got my first CVE assigned!!! \o/
    No, it is not something that I found, it was discovered by Tavis Ormandy. I just assigned this a CVE ID, CVE-2021-3181.
    This is my first, so I am very excited about this! ^_^
  • Besides, there s something more that is in the pipelines. Can t talk about it now, shh. But hopefully very sooooooon!

Other $things! \o/ This month was tiresome, with most of the time being spent on the Debian stuff, I did very little work outside it, really. The issues and patches that I sent are:
  • Issue #700 for redcarpet, asking for a reproducer for CVE-2020-26298 and some additional patch related queries.
  • Issue #7 for in-parallel, asking them to not use relative paths for tests.
  • Issue #8 for in-parallel, reporting a test failure for the library.
  • Issue #2 for rake-ant, asking them to bump their dependencies to a newer version.
  • PR #3 for rake-ant, bumping the dependencies to a newer version, fixing the above issue, heh.
  • Issue #4 for rake-ant, requesting to drop git from their gemspec.
  • PR #5 for rake-ant, dropping git from gemspec, fixing the above issue, heh.
  • Issue #95 for WavPack, asking for a review of past security vulnerabilites wrt v4.70.0.
  • Reviewed PR #128 for ruby-openid, addressing the past regression with CVE fix merge.
  • Reviewed PR #63 for cocoapods-acknowledgements, updating redcarpet to v3.5.1, as a safety measure due to recently discovered vulnerability.
  • Issue #1331 for bottle, asking for relevant commits for CVE-2020-28473 and clarifying other things.
  • Issue #5 for em-redis, reporting test failures on IPv6-only build machines.
  • Issue #939 for eventmachine, reporting test failures for em-redis on IPv6-only build machines.
Until next time.

Russell Coker: Links January 2021

Krebs on Security has an informative article about web notifications and how they are being used for spamming and promoting malware [1]. He also includes links for how to permanently disable them. If nothing else clicking no on each new site that wants to send notifications is annoying. Michael Stapelberg wrote an insightful posts about inefficiencies in the Debian development processes [2]. While I agree with most of his assessment of Debian issues I am not going to decrease my involvement in Debian. Of the issues he mentions the 2 that seem to have the best effort to reward ratio are improvements to mailing list archives (to ideally make it practical to post to lists without subscribing and read responses in the archives) and the issues of forgetting all the complexities of the development process which can be alleviated by better Wiki pages. In my Debian work I ve contributed more to the Wiki in recent times but not nearly as much as I should. Jacobin has an insightful article Ending Poverty in the United States Would Actually Be Pretty Easy [3]. Mark Brown wrote an interesting blog post about the Rust programming language [4]. He links to a couple of longer blog posts about it. Rust has some great features and I ve been meaning to learn it. Scientific America has an informative article about research on the spread of fake news and memes [5]. Something to consider when using social media. Bruce Schneier wrote an insightful blog post on whether there should be limits on persuasive technology [6]. Jonathan Dowland wrote an interesting blog post about git rebasing and lab books [7]. I think it s an interesting thought experiment to compare the process of developing code worthy of being committed to a master branch of a VCS to the process of developing a Ph.D thesis. CBS has a disturbing article about the effect of Covid19 on people s lungs [8]. Apparently it usually does more lung damage than long-term smoking and even 70%+ of people who don t have symptoms of the disease get significant lung damage. People who live in heavily affected countries like the US now have to worry that they might have had the disease and got lung damage without knowing it. Russ Allbery wrote an interesting review of the book Because Internet about modern linguistics [9]. The topic is interesting and I might read that book at some future time (I have many good books I want to read). Jonathan Carter wrote an interesting blog post about CentOS Streams and why using a totally free OS like Debian is going to be a better option for most users [10]. Linus has slammed Intel for using ECC support as a way of segmenting the market between server and desktop to maximise profits [11]. It would be nice if a company made a line of Ryzen systems with ECC RAM support, but most manufacturers seem to be in on the market segmentation scam. Russ Allbery wrote an interesting review of the book Can t Even about millenials as the burnout generation and the blame that the corporate culture deserves for this [12].

Petter Reinholdtsen: Latest Jami back in Debian Testing, and scriptable using dbus

After a lot of hard work by its maintainer Alexandre Viau and others, the decentralized communication platform Jami (earlier known as Ring), managed to get its latest version into Debian Testing. Several of its dependencies has caused build and propagation problems, which all seem to be solved now. In addition to the fact that Jami is decentralized, similar to how bittorrent is decentralized, I first of all like how it is not connected to external IDs like phone numbers. This allow me to set up computers to send me notifications using Jami without having to find get a phone number for each computer. Automatic notification via Jami is also made trivial thanks to the provided client side API (as a DBus service). Here is my bourne shell script demonstrating how to let any system send a message to any Jami address. It will create a new identity before sending the message, if no Jami identity exist already: 
#!/bin/sh
#
# Usage: $0  
#
# Send  to , create local jami account if
# missing.

Iustin Pop: Dealing with evil ads

Background I usually don t mind ads, as not as they not very intrusive. I get that the current media model is basically ad-funded, and that unless I want to pay $1/month or so to 50 web sites, I have to accept ads, so I don t run an ad-blocker. Sure, sometimes are annoying (hey YT, mid-roll ads are borderline), but I ve also seen many good ads, as in interesting or funny even. Well, I don t think I ever bought anything as direct result from ads, so I don t know how useful ads are for the companies, but hey, what do I care. Except there a few ad networks that run what I would say are basically revolting ads. Things I don t want to ever accidentally see while eating, or things that are really make you go WTF? Maybe you know them, maybe you don t, but I guess there are people who don t know how to clean their ears, or people for whom a fast 7 day weight loss routine actually works. Thankfully, most of the time I don t browse sites which use this networks, but randomly they do leak to even sites I do browse. If I m not very stressed already, I can ignore them, otherwise they really, really annoy me. Case in point, I was on Slashdot, and because I was logged on and recently had mod points, the right side column had a check-box disable ads . That sidebar had some relatively meaningful ads, like a VPN subscription (not that I would use it, but it is a tech thing), or even a book about Kali Linux, etc. etc. So I click the disable ads , and the right column goes away. I scroll down happily, only to be met, at the bottom, by the best way to clean your ear , the most 50 useless planes ever built (which had a drawing of something that was for sure never ever built outside of in movies), you won t believe how this child actor looks today , etc.

Solving the problem The above really, really pissed me off, so I went to search how to block ad network . To my surprise, the fix was not that simple, for standard users at least.

Method 1: hosts file The hosts file is reasonable as it is relatively cross-platform (Linux and Windows and Mac, I think), but how the heck do you edit hosts on your phone? And furthermore, it has some significant downsides. First, /etc/hosts lists individual hosts, so for an entire ad network, the example I had had two screens of host names. This is really unmaintainable, since rotating host names, or having a gazillion of them is trivial. Second, it cannot return negative answers. I.e. you have to give each of those hosts a valid IPv4/IPv6, and have something either reply with 404 or another 4xx response, or not listen on port 80/443. Too annoying. And finally, it s a client-side solution, so one would have to replicate it across all clients in a home, and keep it in sync.

Method 2: ad-blockers I dislike ad-blockers on principle, since they need wide permissions on all pages, but it is a recommended solution. However, to my surprise, one finds threads saying ad-blocker foo has whitelisted ad network bar, at which point you re WTF? Why do I use an ad-blocker if they get paid by the lowest of the ad networks to show the ads? And again, it s a client-side solution, and one would have to deploy it across N clients, and keep them in sync, etc.

Method 3: HTTP proxy blocking To my surprise, I didn t find this mentioned in a quick internet search. Well, HTTP proxies have long gone the way of the dodo due to HTTPs everywhere , and while one can still use them even with HTTPS, it s not that convenient:
  • you need to tunnel all traffic through them, which might result in bottlenecks (especially for media playing/maybe video-conference/etc.).
  • or even worse, there might be protocol issues/incompatibilities due to 100% tunneling.
  • running a proxy opens up some potential security issues on the internal network, so you need to harden the proxy as well, and maintain it.
  • you need to configure all clients to know about the proxy (via DHCP or manually), which might or might not work well, since it s client-dependent.
  • you can only block at CONNECT level (host name), and you have to build up regexes for the host name.
On the good side, the actual blocking configuration is centralised, and the only distributed configuration is pointing the clients through the proxy. While I used to run a proxy back in HTTP times, the gains were significant back them (media elements caching, downloads caching, all with a slow pipe, etc.), but today is not worth it, so I ve stopped and won t bring a proxy back just for this.

Method 4: DNS resolver filtering After thinking through all the options, I thought - hey, a caching/recursive DNS resolver is what most people with a local network run, right? How difficult is to block at resolver level? and oh my, it is so trivial, for some resolvers at least. And yes, I didn t know about this a week ago

Response Policy Zones Now, of course, there is a standard for this, called Response Policy Zone, and which is supported across multiple resolvers. There are many tutorials on how to use RPZs to configure things, some of them quite detailed - e.g. this one, or a simple/more straightforward one here. The upstream BIND documentation also explains things quite well here, so you can go that route as well. It looks a bit hairy for me thought, but it works, and since it is a standard, it can be more easily deployed. There are many discussions on the internet about how to configure RPZs, how to not even resolve the names (if you re going to return something explicitly/statically), etc. so there are docs, but again it seems a bit overdone.

Resolver hooks There s another way too, if your resolver allows scripting. For example, the PowerDNS resolver allow Lua scripting, and has a relatively simple API at least, to me it looks way, way simpler than the RPZ equivalent. After 20 minutes of reading the docs, I ended up with this, IMO trivial, solution (in a file named e.g. rules.lua): 
ads = newDS()
ads:add( 'evilads.com', 'evilads.well-known-cdn.com', 'moreads.net' )

function preresolve(dq)
  if ads:check(dq.qname) then
    dq.rcode = pdns.NXDOMAIN
    return true;
  end
  return false;
end
and that s it. Well, enable it/load the file in the configuration, but nothing else. Syntax is pretty straightforward, matching by suffix here, and if you need more complex stuff, you can of course do it; it s just Lua and a simple API. I don t see any immediate equivalent in Bind, so there s that, but if you can use PowerDNS, then the above solution seems simple for simple cases, and could be extended if needed (not sure in which cases). The only other thing one needs to do is to serve the local/custom resolver to all clients, whether desktop or mobile, and that s it. DNS server is bread-and-butter in DHCP, so better support than proxy, and once the host name has been (mis)resolved, nothing is involved anymore in the communication path. True, your name server might get higher CPU usage, but for home network, this should not be a problem. Can this filtering method (either RPZ or hooks) be worked around by ad networks? Sure, like anything. But changing the base domain is not fun. DNSSEC might break it (note Bind RPZ can be configure to ignore DNSSEC), but I m more worried about DNS-over-HTTPS, which I thought initially it s done for the user, but now I m not so sure anymore. Not being in control even of your own DNS resolver seems evil , but what do I know.

Combined authoritative + recursive solution This solution was provided by Guillem Jover, who uses unbound, which is a combined authoritative name server and recursive resolver in one, and dnsmasq (which is even more things, I think):
For my LANs I use unbound, and then block this kind of thing in /etc/unbound/unbound.conf.d/block.conf, with stuff like: 
server:
 local-zone: adsite.example.com refuse
But then for things that are mobile, and might get out of the LAN, such as laptops, I also block with dnsmasq in /etc/dnsmasq.d/block.conf, with stuff like: 
 address=/adsite.example.com/
I still use ublock-origin to block stuff at the browser level, though, for yet an extra layer of noise suppression. :)
Thanks for the info!

Happy browsing! 10 lines of Lua, and now for sure I m going to get even fatter without the this natural method will melt your belly fat in 7 days information. Or I will just throw away banana peels without knowing what I could do with hem. After a few days, I asked myself but ads are not so bad, why did I and then realised that yes, ads are not so bad anymore. And Slashdot actually loads faster So, happy browsing!

Russell Coker: Monopoly the Game

The Smithsonian Mag has an informative article about the history of the game Monopoly [1]. The main point about Monopoly teaching about the problems of inequality is one I was already aware of, but there are some aspects of the history that I learned from the article. Here s an article about using modified version of Monopoly to teach Sociology [2]. Maria Paino and Jeffrey Chin wrote an interesting paper about using Monopoly with revised rules to teach Sociology [3]. They publish the rules which are interesting and seem good for a class. I think it would be good to have some new games which can teach about class differences. Maybe have an Escape From Poverty game where you have choices that include drug dealing to try and improve your situation or a cooperative game where people try to create a small business. While Monopoly can be instructive it s based on the economic circumstances of the past. The vast majority of rich people aren t rich from land ownership.

Debian Long Term Support (LTS) is a project to extend the lifetime of all Debian stable releases to (at least) 5 years. Debian LTS is not handled by the Debian security team, but by a separate group of volunteers and companies interested in making it a success. And Debian Extended LTS (ELTS) is its sister project, extending support to the Jessie release (+2 years after LTS support). This was my fifteenth month as a Debian LTS and sixth month as a Debian ELTS paid contributor.

    Whilst it was indeed fun, I didn t really complete it. No reason, really. But I ll definitely come back stronger next year, heh! :)
    All the solutions thus far could be found here.
  • Did a couple of reviews for some PRs and triaged some bugs here and there, meh.
  • Also did some cloud debugging, not so fun if you ask me, but cool enough to make me want to do it again! ^_^
  • Worked along with pollo, zigo, ehashman, rlb, et al for puppet and puppetserver in Debian. OMG, they re so lovely! <3
  • Ordered some interesting books to read January onward. New year resolution? Meh, not really. Or maybe. But nah.
  • Also did some interesting stuff this month but can t really talk about it now. Hopefully sooooon.
Until next time.
:wq for today.

Next.
