Gunnar Wolf: After miniDebConf Santa Fe

Last week we held our promised miniDebConf in Santa Fe City, Santa Fe province, Argentina just across the river from Paran , where I have spent almost six beautiful months I will never forget. Around 500 Kilometers North from Buenos Aires, Santa Fe and Paran are separated by the beautiful and majestic Paran river, which flows from Brazil, marks the Eastern border of Paraguay, and continues within Argentina as the heart of the litoral region of the country, until it merges with the Uruguay river (you guessed right the river marking the Eastern border of Argentina, first with Brazil and then with Uruguay), and they become the R o de la Plata. This was a short miniDebConf: we were lent the APUL union s building for the weekend (thank you very much!); during Saturday, we had a cycle of talks, and on sunday we had more of a hacklab logic, having some unstructured time to work each on their own projects, and to talk and have a good time together. We were five Debian people attending: santiago debacle eamanu dererk gwolf @debian.org. My main contact to kickstart organization was Mart n Bayo. Mart n was for many years the leader of the Technical Degree on Free Software at Universidad Nacional del Litoral, where I was also a teacher for several years. Together with Leo Mart nez, also a teacher at the tecnicatura, they contacted us with Guillermo and Gabriela, from the APUL non-teaching-staff union of said university. We had the following set of talks (for which there is a promise to get electronic record, as APUL was kind enough to record them! of course, I will push them to our usual conference video archiving service as soon as I get them)

Lisandro Dami n Nicanor P rez Meyer: Mini DebConf 2023 in Montevideo, Uruguay

15 years, "la ni a bonita", if you ask many of my fellow argentinians, is the amount of time I haven't been present in any Debian-related face to face activity. It was already time to fix that. Thanks to Santiago Ruano Rinc n and Gunnar Wolf that proded me to come I finally attended the Mini DebConf Uruguay in Montevideo. Me in Montevideo, Uruguay I took the opportunity to do my first trip by ferry, which is currently one of the best options to get from Buenos Aires to Montevideo, in my case through Colonia. Living ~700km at the south west of Buenos Aires city the trip was long, it included a 10 hours bus, a ferry and yet another bus... but of course, it was worth it. In Buenos Aires' port I met Emmanuel eamanu Arias, a fellow Argentinian Debian Developer from La Rioja, so I had the pleasure to travel with him. To be honest Gunnar already did a wonderful blog post with many pictures, I should have taken more. I had the opportunity to talk about device trees, and even look at Gunnar's machine one in order to find why a Display Port port was not working on a kernel but did in another. At the same time I also had time to start packaging qt6-grpc. Sadly I was there just one entire day, as I arrived on Thursday afternoon and had to leave on Saturday after lunch, but we did have a lot of quality Debian time. I'll repeat here what Gunnar already wrote:
We had a long, important conversation about an important discussion that we are about to present on debian-vote@lists.debian.org.
Stay tuned on that, I think this is something we should all get involved. All in all I already miss hacking with people on the same room. Meetings for us mean a lot of distance to be traveled (well, I live far away of almost everything), but I really should try to this more often. Certainly more than just once every 15 years :-)

Russ Allbery: Review: The Light Brigade

Review: The Light Brigade, by Kameron Hurley
Publisher: Saga
Copyright: 2019
ISBN: 1-4814-4798-X
Format: Kindle
Pages: 355
In the wake of the Blink, which left a giant crater where S o Paulo was, Dietz signed up for the military. To be a hero. To satisfy an oath of vengeance. To kill aliens. Corporations have consumed the governments that used to run Earth and have divided the world between them. Dietz's family, before the Blink, were ghouls in Tene-Silva territory, non-citizens who scavenged a precarious life on the margins. Citizenship is a reward for loyalty and a mechanism of control. The only people who don't fit into the corporate framework are the Martians, former colonists who went dark for ten years and re-emerged as a splinter group offering to use their superior technology to repair environmental damage to the northern hemisphere caused by corporate wars. When the Blink happens, apparently done with technology far beyond what the corporations have, corporate war with the Martians is the unsurprising result. Long-time SF readers will immediately recognize The Light Brigade as a response to Starship Troopers with far more cynical world-building. For the first few chapters, the parallelism is very strong, down to the destruction of a large South American city (S o Paulo instead of Buenos Aires), a naive military volunteer, and horrific basic training. But, rather than dropships, the soldiers in Dietz's world are sent into battle via, essentially, Star Trek transporters. These still very experimental transporters send Dietz to a different mission than the one in the briefing. Advance warning that I'm going to talk about what's happening with Dietz's drops below. It's a spoiler, but you would find out not far into the book and I don't think it ruins anything important. (On the contrary, it may give you an incentive to stick through the slow and unappealing first few chapters.) I had so many suspension of disbelief problems with this book. So many. This starts with the technology. The core piece of world-building is Star Trek transporters, so fine, we're not talking about hard physics. Every SF story gets one or two free bits of impossible technology, and Hurley does a good job showing the transporters through a jaundiced military eye. But, late in the book, this technology devolves into one of my least-favorite bits of SF hand-waving that, for me, destroyed that gritty edge. Technology problems go beyond the transporters. One of the bits of horror in basic training is, essentially, torture simulators, whose goal is apparently to teach soldiers to dissociate (not that the book calls it that). One problem is that I never understood why a military would want to teach dissociation to so many people, but a deeper problem is that the mechanics of this simulation made no sense. Dietz's training in this simulator is a significant ongoing plot point, and it kept feeling like it was cribbed from The Matrix rather than something translatable into how computers work. Technology was the more minor suspension of disbelief problem, though. The larger problem was the political and social world-building. Hurley constructs a grim, totalitarian future, which is a fine world-building choice although I think it robs some nuance from the story she is telling about how militaries lie to soldiers. But the totalitarian model she uses is one of near-total information control. People believe what the corporations tell them to believe, or at least are indifferent to it. Huge world events (with major plot significance) are distorted or outright lies, and those lies are apparently believed by everyone. The skepticism that exists is limited to grumbling about leadership competence and cynicism about motives, not disagreement with the provided history. This is critical to the story; it's a driver behind Dietz's character growth and is required to set up the story's conclusion. This is a model of totalitarianism that's familiar from Orwell's Nineteen Eighty-Four. The problem: The Internet broke this model. You now need North Korean levels of isolation to pull off total message control, which is incompatible with the social structure or technology level that Hurley shows. You may be objecting that the modern world is full of people who believe outrageous propaganda against all evidence. But the world-building problem is not that some people believe the corporate propaganda. It's that everyone does. Modern totalitarians have stopped trying to achieve uniformity (because it stopped working) and instead make the disagreement part of the appeal. You no longer get half a country to believe a lie by ensuring they never hear the truth. Instead, you equate belief in the lie with loyalty to a social or political group, and belief in the truth with affiliation with some enemy. This goes hand in hand with "flooding the zone" with disinformation and fakes and wild stories until people's belief in the accessibility of objective truth is worn down and all facts become ideological statements. This does work, all too well, but it relies on more information, not less. (See Zeynep Tufekci's excellent Twitter and Tear Gas if you're unfamiliar with this analysis.) In that world, Dietz would have heard the official history, the true history, and all sorts of wild alternative histories, making correct belief a matter of political loyalty. There is no sign of that. Hurley does gesture towards some technology to try to explain this surprising corporate effectiveness. All the soldiers have implants, and military censors can supposedly listen in at any time. But, in the story, this censorship is primarily aimed at grumbling and local disloyalty. There is no sign that it's being used to keep knowledge of significant facts from spreading, nor is there any sign of the same control among the general population. It's stated in the story that the censors can't even keep up with soldiers; one would have to get unlucky to be caught. And yet the corporation maintains preternatural information control. The place this bugged me the most is around knowledge of the current date. For reasons that will be obvious in a moment, Dietz has reasons to badly want to know what month and year it is and is unable to find this information anywhere. This appears to be intentional; Tene-Silva has a good (albeit not that urgent) reason to keep soldiers from knowing the date. But I don't think Hurley realizes just how hard that is. Take a look around the computer you're using to read this and think about how many places the date shows up. Apart from the ubiquitous clock and calendar app, there are dates on every file, dates on every news story, dates on search results, dates in instant messages, dates on email messages and voice mail... they're everywhere. And it's not just the computer. The soldiers can easily smuggle prohibited outside goods into the base; knowledge of the date would be much easier. And even if Dietz doesn't want to ask anyone, there are opportunities to go off base during missions. Somehow every newspaper and every news bulletin has its dates suppressed? It's not credible, and it threw me straight out of the story. These world-building problems are unfortunate, since at the heart of The Light Brigade is a (spoiler alert) well-constructed time travel story that I would have otherwise enjoyed. Dietz is being tossed around in time with each jump. And, unlike some of these stories, Hurley does not take the escape hatch of alternate worlds or possible futures. There is a single coherent timeline that Dietz and the reader experience in one order and the rest of the world experiences in a different order. The construction of this timeline is incredibly well-done. Time can only disconnect at jump and return points, and Hurley maintains tight control over the number of unresolved connections. At every point in the story, I could list all of the unresolved discontinuities and enjoy their complexity and implications without feeling overwhelmed by them. Dietz gains some foreknowledge, but in a way that's wildly erratic and hard to piece together fast enough for a single soldier to do anything about the plot. The world spins out of control with foreshadowing of grimmer and grimmer events, and then Hurley pulls it back together in a thoroughly satisfying interweaving of long-anticipated scenes and major surprises. I'm not usually a fan of time travel stories, but this is one of the best I've read. It also has a satisfying emotional conclusion (albeit marred for me by some unbelievable mystical technobabble), which is impressive given how awful and nasty Hurley makes this world. Dietz is a great first-person narrator, believably naive and cynical by turns, and piecing together the story structure alongside the protagonist built my emotional attachment to Dietz's character arc. Hurley writes the emotional dynamics of soldiers thoughtfully and well: shit-talking, fights, sudden moments of connection, shared cynicism over degenerating conditions, and the underlying growth of squad loyalty that takes over other motivations and becomes the reason to keep on fighting. Hurley also pulled off a neat homage to (and improvement on) Starship Troopers that caught me entirely by surprise and that I've hopefully not spoiled. This is a solid science fiction novel if you can handle the world-building. I couldn't, but I understand why it was nominated for the Hugo and Clarke awards. Recommended if you're less picky about technological and social believability than I am, although content warning for a lot of bloody violence and death (including against children) and a horrifically depressing world.

Gunnar Wolf: Yes! I can confirm that...

I am very very (very very very!) happy to confirm that... This year, and after many years of not being able to, I will cross the Atlantic. To do this, I will take my favorite excuse: Attending DebConf! So, yes, this image I am pasting here is as far as you can imagine from official promotional material. But, having bought my plane tickets, I have to start bragging about it ;-) In case it is of use to others (at least, to people from my general geographic roundabouts), I searched for plane tickets straight from Mexico. I was accepting my lack of luck, facing an over-36-hour trip(!!) and at very high prices. Most routes were Mexico- central_europe -Arab Emirates-South Africa... Great for collecting frequent-flier miles, but terrible for anything else. Of course, requesting a more logical route (say, via Sao Paulo in Brazil) resulted in a price hike to over US$3500. Not good. I found out that Mexico-Argentina tickets for that season were quite agreeable at US$800, so I booked our family vacation to visit the relatives, and will fly from there at US$1400. So, yes, in a 48-hr timespan I will do MEX-GRU-ROS, then (by land) Rosario to Buenos Aires, then AEP-GRU-JNB-CPT. But while I am at DebConf, Regina and the kids will be at home with the grandparents and family and friends. In the end, win-win with just an extra bit of jetlag for me ;-) I *really* expect flights to be saner for USians, Europeans, and those coming from further far away. But we have grown to have many Latin Americans, and I hope we can all meet in CPT for the most intense weeks of the year! See you all in South Africa!

Mart n Ferrari: Tales from the SRE trenches: What can SRE do for you?

This is the fourth part in a series of articles about SRE, based on the talk I gave in the Romanian Association for Better Software. Previous articles can be found here: part 1, part 2, and part 3. As a side note, I am writing this from Heathrow Airport, about to board my plane to EZE. Buenos Aires, here I come!

So, what does SRE actually do? Enough about how to keep the holy wars under control and how to get work away from Ops. Let's talk about some of the things that SRE does. Obviously, SRE runs your service, performing all the traditional SysAdmin duties needed for your cat pictures to reach their consumers: provisioning, configuration, resource allocation, etc. They use specialised tools to monitor the service, and get alerted as soon as a problem is detected. They are also the ones waking up to fix your bugs in the middle of the night. But that is not the whole story: reliability is not only impacted by new launches. Suddenly usage grows, hardware fails, networks lose packets, solar flares flip your bits... When working at scale, things are going to break more often than not. You want these breakages to affect your availability as little as possible, there are three strategies you can apply to this end: minimise the impact of each failure, recover quickly, and avoid repetition. And of course, the best strategy of them all: preventing outages from happening at all.

Minimizing the impact of failures A single failure that takes the whole service down will affect severely your availability, so the first strategy as an SRE is to make sure your service is fragmented and distributed across what is called "failure domains". If the data center catches fire, you are going to have a bad day, but it is a lot better if only a fraction of your users depend on that one data center, while the others keep happily browsing cat pictures. SREs spend a lot of their time planning and deploying systems that span the globe to maximise redundancy while keeping latencies at reasonable levels.

Recovering quickly Many times, retrying after a failure is actually the best option. So another strategy is to automatically restart in milliseconds any piece of your system that fails. This way, less users are affected, while a human has time to investigate and fix the real problem. If a human needs to intervene, it is crucial that they get notified as fast as possible, and that they have quick access to all the information that is needed to solve the problem: detailed documentation of the production environment, meaningful and extensive monitoring, play-books1, etc. After all, at 2 AM you probably don't remember in which country the database shard lives, or what were the series of commands to redirect all the traffic to a different location. Implementing monitoring and automated alerts, writing documentation and play-books, and practising for disaster are other areas where SREs devote much effort.

Avoiding repetition Outages happen, pages ring, problems get fixed, but it should always be a chance for learning and improving. A page should require a human to think about a problem and find a solution. If the same problem keeps appearing, the human is not needed any more: the problem needs to be fixed at the root. Another key aspect of dealing with incidents is to write post-mortems2. Every incident should have one, and these should be tools for learning, not finger-pointing. Post-mortems can be an excellent tool, if people are honest about their mistakes, they are not used to blame other people, and issues are followed up by bug reports and discussions.

Preventing outages Of course nobody can prevent hard drives from failing, but there are certain classes of outages that can be forecasted with careful analysis. Usage spikes can bring a service down, but an SRE team will ensure that the systems are load-tested at higher-than-normal rates. They could also be prepared to quickly scale the service, provided the monitoring system will alert as soon as a certain threshold is reached. Monitoring is actually the key part in this: measuring relevant metrics for all the components of a system, and following their trends over time, SREs can completely avoid many outages: latencies growing out of acceptable bounds, disks filling up, progressive degradation of components, are all examples of typical problems automatically monitored (and alerted on) in an SRE team.
This is getting pretty long, so the next post will be the last one of these series, with some extra tips from SRE experience that I am sure can be applied in many places.

  1. A play-book is a document containing critical information needed when dealing with a specific alert: possible causes, hints for troubleshooting, links to more documentation. Some monitoring systems will automatically add a play-book URL to every alert sent, and you should be doing it too.
  2. Similarly to their real-life counterparts, a post-mortem is the process of examining a dead body (the outage), gutting it out and trying to understand what caused its demise.

Martín Ferrari: Romania

It's been over 2 years since I decided to start a new, nomadic life. I had the idea of blogging about this experience as it happened, but not only I am incredibly lazy when it comes to writing, most of the time I have been too busy just enjoying this lifestyle! The TL;DR version of these last 2 years: And now, I am in Cluj-Napoca, Romania.

Gunnar Wolf: Pan Latin American Hashomer, 18 years later

Pan Latin American Hashomer, 18 years later
In 1994/1995, I spent probably the most unique and memorable year of my life with the people of several Zionist youth movements in Israel, working in a kibutz, learning in Jerusalem... In 1995, after most of my group returned to Mexico, I stuck with the newly arrived South American group of Hashomer Hatzair (plus some affiliates). We were 18-19. And 18-19 years later, here we are: Fabi n (from Buenos Aires) and Fabiana (from Montevideo), living in Buenos Aires, with two kids. Regina (from Paran ) and me (from Mexico), living in Mexico, no kids yet. Two couples. Three countries. Four cities. And a lovely evening. And the hopes to stay in touch, to meet every year when we come to visit Argentina.

Martín Ferrari: Living in Buenos Aires: first week

Continuing my nomadic experiment, I have just arrived in Buenos Aires. My plan is to live here for 3 months, working and enjoying the city like I never did before: I always lived in the suburbs and only came to the city to work or study. After a few days seeing my immediate family and some close friends, today I finally went out, taking advantage of a beautiful spring day. And my first stop is the National Library. Biblioteca Nacional -   Dan DeLuca, downloaded from Wikipedia, licenced as Creative Commons Attribution 2.0 Generic I came with the intention of working a bit on some projects, but arriving as a visitor forbade me to enter the most interesting places of the library (now I have registered so next time they will not treat me as a tourist :)). It is an imposing building, I have seen it a few times before, but never entered it. I only learned today that in these grounds there used to be the presidential residence, back in Per n days, and then it was thoroughly demolished by the barbarians of the '55 coup. I also learned this new building was only opened in 1992, which is surprising, as I don't remember the fact at all, and I was already 14.

Martín Ferrari: Of Grafton street and Hanbury lane

It finally happened, I'm at the boarding gate 423, about to get into the plane that will take me out of Dublin. It seems I didn't get convinced by this article. Still, I've tried to see most of the things on that list, and see a fair bit of the island. I am not sad, I was expecting myself to break down and make a big Greek drama, but nothing like that happened. In the end, Dublin is the one place (with Buenos Aires) where I'll be coming back often. Still, this song has been in my head for days.

Gunnar Wolf: Married!

So, yay! Title says it all! On Saturday September 22, Regina and I got married in my parents' house, in Cuernavaca, Morelos. We had a very very nice little party with our family and a small group of friends Of course, due to the nature of our life, we could not forego inviting our family and friends in Argentina, as well as those in other parts of the world, so we set up a simple video stream so that our friends could follow along And they did, with much greater success than what I expected! So, besides those people present with us in Cuernavaca, we had people tuning in (at least to the degree I could get from the log files) from Argentina (Buenos Aires, Paran , Formosa), Austria, Canada, France, Germany, Hungary, Italy, Macedonia, Mexico, Poland, Spain, Sweden and the United States. This next Saturday (September 29) we will have a second party, to which our friends in Mexico are invited, at home. And for the people from far away,, the stream will be available again Expect at least one interesting surprise :) PS- Visit also our wedding page, with some photos, video, and general information (Warning! Part of it is outdated by now)

Christian Perrier: DebConf running: take 5 (South-West suburbs of Managua)

The challenge is now more and more to find good places to run without too much cars and noises....and not too far away. Today, I think I made it well..:-) After a look on the map, and some wild guess from what I now know of the way the city is organized, I decided to go south-west of Managa, from the hotel Seminole. This is again a hilly run because, anyway, wherever you go south in Managua, you're going up. Ralf, who arrived just yesterday, joined me and, I guess, enjoyed the run. After going through an obviously quite rich neighbourhood with nice villas, gardeners, huge US truck-style cars, we went close to the Mormonschurch...and a mosque, then headed westward close to "Colegio Americano", with fences, walls, guards in the corner, etc. Seems that any tiny bit of USA in the world needs an army to protect it. Crossing la Pista Suburbana, we then went on a very quiet roads towards the hill, in a very green and peaceful area. House there were really not as fancy as in other places, even seeming quite "poor" in some way. However, we never felt any problem and people we meet on the way are always friendly and smiling : "Hola", "Buenos Dias", etc. At the end of the road, after about half an hour, we decided to head back. However, as going back the same way is boring, I suggested we head up west as my phone's map (it is very helpful to have a smartphone with GPS and Google Maps for wandering through unknwon places) was mentioning another road going north-west a little bit westward. So we entered a small trail between house farms...with dogs! These were a bit "scary" as they were barking at us and of course running entirely freely. On the other hand, none was really aggressive and we had no problem. I however saw a few people really staring at us as I guess there are not so many runners in this place..:-). But still, we never felt unsafe: just in a quite uncommon place. After abotu 500m we found the "road" that was on my map: indeed a path going down slowly along the hill. And there was the marvel. An incredible panoramic view going going the volcanoes that are East and North of Leon : San Cristobal, Telica Rota, Pilas elHoj and last but definitely not least: EL MOMOTOMBO. A nearly perfect pyramid-style volcano that lies about 50km north-west of Managua, on the eastern shore of Managua Lake. The view there is...just fantastic with also a 180 panorama to West and North-West of the lake and the volcanoes area. After this, all we had to do was heading back to the hotel and share this with you...:-) As usual, the full GPS trace is here.

Gunnar Wolf: I am going to DebConf12!

I have just bought our plane tickets to Managua, so I can finally say this: Going-to-banner-180x150-grey Yes, many of you will ask what happened, I was bragging everywhere I wanted to go by land, driving from Mexico City to Managua. I'd love to, and I'm sure it's completely doable... But we have family issues to attend on July 21, in Argentina. So we will have a beautiful flight schedule (and carbon footprint) for this July:
June 30
Mexico San Salvador Managua, 17:35-20:30. Yes, this means I will not be in Mexico to cast my vote on July 1st. Well, I had already accepted this would happen... And the price difference was quite sensible.
July 15
Managua San Jos Mexico, 16:25-22:20
July 16
Mexico Santiago Buenos Aires (AEP), 20:30-09:55
July 23
Buenos Aires (EZE) Lima Mexico, 08:35-19:00
Several people have asked me on the best airline options for this trip. In our case, to Managua, it was with TACA, US$518 total. You can get tickets for ~US$30 less, but the flight goes through Panama instead of San Salvador, for an extra 1000Km And instead of ~3hr it makes slightly over 6. Yes, on our way back we will be routed a bit South to San Jos , but it's not as bad, and it's for a very short layover. For Argentina? Well, we have always found LAN to be the cheapest and most convenient. This time, TACA/Avianca was a very close second, which lost due to almost doubling the flight+layover time Why aren't we taking a Mexico Managua Buenos Aires flight instead? Because it's ~US$150 more expensive per person. Not *that* much, but still some money. And by returning to Mexico and having a night at home, we will save us the hassle of carrying Winter clothes to Nicaragua and Summer clothes to Argentina. Oh, and if you are planning on dropping by home while we are away and robbing all of our stuff: There's not that much to take from there, and we have already arranged for somebody to be there while we are away. But thanks for thinking about us, anyway! [update] And what about DebConf12 registration? When is the system opening for us all to register? Soon, dear friends, we are talking about some related issues, and you will have your registrationi open soon.

Gunnar Wolf: e-voting: Something is brewing in Jalisco...

There's something brewing, moving in Jalisco (a state in Mexico's West, where our second largest city, Guadalajara, is located). And it seems we have an opportunity to participate, hopefully to be taken into account for the future. Ten days ago, I was contacted by phone by the staff of UDG Noticias, for an interview on the Universidad de Guadalajara radio station. The topic? Electronic voting. If you are interested in what I said there, you can get the interview from my webpage. I held some e-mail contact with the interviewer, and during the past few days, he sent me some links to notes in the La Jornada de Jalisco newspaper, and asked for my opinion on them: On September 23, a fellow UNAM researcher, C sar Astudillo, claims the experience in three municipalities in Jalisco prove that e-voting is viable in the state, and today (September 26), third generation of an electronic booth is appearingly invulnerable. Of course, I don't agree with the arguments presented (and I'll reproduce the mails I sent to UDG Noticias about it before my second interview just below They are in Spanish, though). However, what I liked here is that it does feel like a dialogue. Their successive texts seem to answer to my questioning. So, even though I cannot yet claim this is a real dialogue (it would be much better to be able to sit down face to face and have a fluid conversation), it feels very nice to actually be listened to from the other side! My answer to the first note:
El tema de las urnas electr nicas sigue dando de qu hablar por ac en Jalisco... nosotros en Medios UDG hemos presentado distintas voces como la del Dr. Gabriel Corona Armenta, que est a favor del voto electr nico, del Dr. Luis Antonio Sobrado, magistrado presidente del tribunal supremo de elecciones de Costa Rica, quien nos habl sobre los 20 MDD que les cuesta implementar el sistema por lo que no lo han logrado hasta el momento, pudimos hablar hasta argentina con Federico Heinz y su rotunda oposici n al voto electr nico y por supuesto la entrevista que le realizamos a usted. Sin embargo este d a La Jornada Jalisco publica la siguiente nota http://www.lajornadajalisco.com.mx/2011/09/23/index.php?section=politica... nos gustar a saber cu l es su punto de vista al respecto, quedo a la espera de su respuesta
Hola, Pues... Bueno, s que el IFE hizo un desarrollo muy interesante y bien hecho hace un par de a os, dise ando desde cero las urnas que propon an emplear, pero no se instrumentaron fuera de pilotos (por cuesti n de costos, hasta donde entiendo). Se me hace triste y peligroso que el IEPC de Jalisco est proponiendo, teniendo ese antecedente, la compra de tecnolog a prefabricada, y confiando en lo que les ofrece un proveedor. Se me hace bastante iluso, directamente, lo que propone el t tulo: comicios en tres municipios prueban la viabilidad del voto electr nico en todo el estado . Pong moslo en estos t rminos: El que no se caiga una choza de l mina con estructura de madera demuestra que podemos construir rascacielos de l mina con estructura de madera? Ahora, un par de p rrafos que me llaman la atenci n de lo que publica esta nota de La Jornada:
la propuesta de realizar la elecci n en todo el estado con urnas electr nicas que desea llevar a cabo el Instituto Electoral y de Participaci n Ciudadana (IEPC) es viable, pues los comicios realizados en tres municipios son pruebas suficientes para demostrar que la urna es fiable
y algunos p rrafos m s adelante,
Cu ntas experiencias m s se necesitan para saber si es confiable, 20, 30, no lo s (...) Pero cuando se tiene un diagn stico real, efectivo y serio de cu ndo t cnicamente procede, se puede tomar la decisi n
Como lo menciono en mi art culo... No podemos confundir a la ausencia de evidencia con la evidencia de ausencia. Esto es, que en un despliegue menor no haya habido irregulares no significa que no pueda haberlas. Que haya pa ses que operan 100% con urnas electr nicas no significa que sea el camino a seguir. Hay algunas -y no pocas- experiencias de fallas en diversos sentidos de urnas electr nicas, y eso demuestra que no puede haber confianza en las implementaciones. Aunque el equipo nos saliera gratis (que no es el caso), hay que invertir recursos en su resguardo y mantenimiento. Aunque se generara un rastro impreso verificado por el votante (que s lo ha sido el caso en una peque a fracci n de las estacione de votaci n), nada asegura que los resultados reportados por el equipo sean siempre consistentes con la realidad. El potencial para mal uso que ofrecen es demasiado. Saludos,
And to September 26th:
Disculpe que lo molestemos otra vez, pero este d a fue publicada otra nota m s sobre el tema de las Urnas electr nicas en Jalisco donde se asegura que la urna es invulnerable. http://www.lajornadajalisco.com.mx/2011/09/26/index.php?section=politica... nos podr a conceder unos minutos para hablar con usted, como la vez pasada, v a telef nica sobre el caso espec fico de Jalisco, en referencia a estas notas publicadas recientemente? si es posible podr a llamarle este d a a las 2 pm? Quedo a la espera de su respuesta agradeci ndole su ayuda, apreciamos mucho esta colaboraci n que est haciendo con nosotros
Hola, ( ) Respecto a esta nota: Nuevamente, ausencia de evidencia no es evidencia de ausencia. Se le permite a un peque o segmento de personas jugar con una m quina. Significa eso que fue una prueba completa, exhaustiva? No, s lo que ante un jugueteo casual no pudieron encontrar fallos obvios y graves. Un verdadero proceso que brindara confianza consistir a en (como lo hicieron en Brasil - Y resultaron vulnerables) convocar a la comunidad de expertos en seguridad en c mputo a hacer las pruebas que juzguen necesarias teniendo un nivel razonable de acceso al equipo. Adem s, la seguridad va m s all de modificar los resultados guardados. Un par de ejemplos que se me ocurren sin darle muchas vueltas:
  • Qu pasa si meto un chicle a la ranura lectora de tarjeta magn tica?
  • Qu pasa si golpeo alguna de las teclas lo suficiente para hacerla un poquito menos sensible sin destruirla por completo? (o, ya entrados en gastos, si la destruyo)
La negaci n de servicio es otro tipo de ataque con el cual tenemos que estar familiarizados. No s lo es posible modificar el sentido de la votaci n, sino que es muy f cil impedir que la poblaci n ejerza su derecho. Qu har an en este caso? Bueno, podr an caer de vuelta a votaci n sobre papel - Sobre hojas de un block, probablemente firmadas por cada uno de los funcionarios, por ejemplo. Pero si un atacante bloque la lectura de la tarjeta magn tica, que es necesaria para que el presidente de casilla la marque como cerrada, despoj de su voto a los usuarios. S , se tienen los votos impresos (que, francamente, me da mucho gusto ver que esta urna los maneja de esta manera). El conteo es posible, aunque un poco m s inc modo que en una votaci n tradicional (porque hay que revisar cu les son los que est n marcados como invalidados - no me queda muy claro c mo es el escenario del elector que vot por una opci n, se imprimi otra, y el resultado fue corregido y marcado como tal)... Pero es posible. Sin embargo, y para cerrar con esta respuesta: Si hacemos una corrida de prueba, en circunstancias controladas, obviamente no se notar n los much simos fallos que una urna electr nica puede introducir cuando los "chicos malos" son sus programadores. Podemos estar seguro que este marcador Atlas-Chivas-Cruz Azul tenga el mismo ndice de fiabilidad como una elecci n de candidatos reales, uno de los cuales puede haberle pagado a la empresa desarrolladora para manipular la elecci n? Y a n si el proceso fuera perfecto, indican aqu que est n _intentando_ licitar estas urnas (y nuevamente, si lo que menciona esta nota es cierto, son de las mejores urnas disponibles, y han atendido a muchos de los se alamientos - Qu bueno!)... Para qu ? Qu nos van a dar estas urnas, qu va a ganar la sociedad? Mayor rapidez? Despreciable - Media hora de ganancia. A cambio de cu nto dinero? Mayor confiabilidad? Me queda claro que no, siendo que no s lo somos cuatro trasnochados los que ponemos su sistema en duda, sino que sus mismos proponentes apuntan a la duda generalizada. La frase con la que cierra la nota se me hace digna para colgar un ep logo: "en ese futuro quiz no tan distante la corrupci n tambi n ocurre y sta se debe siempre al factor humano". Y el factor humano sigue ah . Las urnas electr nicas son programadas por personas, por personas falibles. Sin importar del lado que est n, recordar n la pol mica cuando se hizo p blico que la agregaci n de votos en el 2006 fue supervisada por la empresa Hildebrando, propiedad del cu ado del entonces candidato a la presidencia Felipe Calder n. Qu evita que caigamos en un escenario similar, pero ampliamente distribu do? Y aqu hay que referirnos a la sentencia de la Suprema Corte de Alemania: En dicho pa s, las votaciones electr nicas fueron declaradas anticonstitucionales porque s lo un grupo de especialistas podr an auditarlas. Una caja llena de papeles con la evidencia clara del sentido del voto de cada participante puede ser comprendida por cualquier ciudadano. El c digo que controla a las urnas electr nicas, s lo por un peque o porcentaje de la poblaci n.

Russell Coker: Virgin Refunds Me $200

Virgin Mobile Excessive BillingIn my previous post about the Xperia X10 I mentioned being billed excessively for bandwidth use [1].On Friday when I phoned Virgin I was repeatedly told that there was nothing that could be done about the bill. I demanded to be transferred to someone with authority to change my bill, I was told that wasn t possible so I demanded to be transferred to a supervisor. As no supervisors were available at the time I had to be called back.The Supervisor Tonight I received a call from someone who s employed to deal with disputed bills, after explaining the situation I was offered a discount of $150, that s a 64% discount on the $234. I rejected that offer and explained that I only used 7% more data than was permitted in the month and only did so because of a previous phone call with a Virgin representative telling me that the billing period ended at the month end (which I couldn t verify at the time because the Virgin CRM system was down [2]). Thus it doesn t seem reasonable to charge me 7* the regular billing amount for the entire month.I was asked what I thought would be a reasonable extra charge, I suggested 7.4% more than the $39 contract, IE an extra $3 that wasn t well received. Then I suggested that as the $49 Smart Cap plan would have covered the extra data use it could be reasonable for me to pay $49 for the month. The Virgin representative then offered me a $200 discount on the bill and I accepted that. So I got a 85.5% discount on the disputed amount, that s not too bad, it s enough to make this scam less profitable to Virgin (particularly when I publish information about it) and enough to make it not worth the effort of a TIO complaint.That makes it a bill of $102.36 instead of the original $302.36. That is $29 for one month of the Big Cap $29 for my wife, $39 for one month of the Smart Cap $39 for me, $33.99 for Virgin excessive bandwidth charges (down from $233.99), and $0.37 Account Charges which is described as a Payment Processing Fee presumably a fee for paying by credit card.The Ethical IssueTo make it clear, I think that only a minority of mobile phone customers have an ability to track their bandwidth and understand their bill which equals mine. I also think that only a minority of customers are as willing as I am to argue with random people about such things. I am sure that employees of Virgin Mobile know this and they devised a billing plan to trap customers. I think that this doesn t comply with the ethical standards that Richard Branson has advocated in several TV interviews that I have watched.The Next IssueNow the only remaining issue is that I signed up for an offer 3 Months Free ^ access fee on Topless, Smart & Easy caps with this phone. Save up to $267, just by buying online which continued Promo code: reggae Use this promo code & we ll automatically credit your first 3 months access fees , but so far they have not credited it. It s a pity I didn t realise this before and get it done in the same call.ConclusionI m starting to regret not keeping my LG U990 Viewty with a pre-paid SIM from Lebara [3] or Amaysim [4]. Amaysim has a minimum pre-paid value of $10 which lasts for 90 days, and the SIM will then receive calls for 180 days after the credit has run out this means $10 per 260 days (an average of $7.11 per year) if you just want to receive calls. Lebara has a period of 120 days before the number expires, so that means it costs $10 per 210 days or an average of $5.75 per year to receive calls only.Telstra charges $150 for one year of mobile net access which allows 10G of data transfer [5]. So it seems that a good option would be an old phone and a new Android tablet. $150 per year ($12.50 per month) for mobile net access and something between $5.75 and $40 per year for phone access (depending on whether you want to make calls) gives enough savings over the cost of a post-paid plan to buy a decent tablet.I think that the Android phone is definitely the best deal for my wife because she really only wants to carry one device, also she likes having longer conversations on the phone so the plan where she gets up to 450 minutes for $29 per month is a reasonable deal particularly as calls to me are free and calls to her relatives will be free if they get Virgin phones (something that now seems doubtful given their over-billing).I m happy to carry multiple devices (my past record is having four mobile phones and getting a tailor-made coat to fit all the geek stuff I carried) so a phone and a tablet is a reasonable option for me. But the Xperia X10 will do the job for the next two years and I ve got no great regrets.On the up-side, Virgin did send me a couple of free movie tickets after their CRM stuff-up.

Paul Wise: Another year, another log entry

It has been almost a full year since my last log entry. It has been a busy work year, I attended some nice conferences and did minimal FLOSS stuff. On the work side of things I was a third of an Australian VoIP startup that came and went. I setup Debian servers, installed OpenSIPS and associated software, wrote OpenSIPS scripts, wrote peripheral software and did customer support. We had a good thing going there for a while, some fans on the Whirlpool forums but in the end there wasn't enough money for the requisite marketing and local market circumstances were squeezing Australian VoIP providers anyway. On the conference side of things I went to LCA 2010, the Thai Mini-DebCamp 2010, DebConf10 and FOSSASIA 2010. Had a great time at all of them. At LCA 2010 in windy Wellington, New Zealand the distributions summit organised by Martin Krafft was one of the highlights. It was dominated by Debian/Ubuntu talks but there were some other interesting ones, especially the one on GoboLinux's integration of domain-specific package managers. Also excellent were the keynotes given by Gabriella Coleman (Best & worst of times), Mako Hill (Antifeatures) and others, which I felt gave LCA an improved and very welcome focus on software freedom. There were quite a few Debian folks at LCA, it was great to hang out with them during the week and afterwards. Monopedal sumo with mako and others was hilarious fun. At the Thailand Mini-DebCamp 2010 in Khon Kaen, I was glad to see Andrew Lee (Taiwan) and Christian Perrier (France) again and meet Yukiharu YABUKI (Japan) and Daiki Ueno (Japan). In addition to the five international folks, there were quite a few locals, including Thailand's currently sole Debian member, Theppitak Karoonboonyanan. The event was hosted at Khon Kaen University and opened with my talk about the Debian Social Contract and the Debian Free Software Guidelines. This was followed by a number of talks about Debian package building, a 3-day BSP where we touched 57 bugs, a great day of sightseeing and talks about i18n, derivative distros, keysigning, mirrors, contribution and a discussion about DebConf. During the week there was also the usual beersigning, combined with eating of unfamiliar and "interesting" Thai snacks. After the conference Andrew and I roamed some markets in Bangkok and got Thai massages. Beforehand I also visited a friend from my travels on the RV Heraclitus in Chiang Mai, once again experiencing the awesomeness of trains in Asia, unfortunately during the dry season this time. I took a lot of photos during my time in Thailand and ate a lot of great and spicy food. As a vegetarian I especially appreciated the organiser's efforts to accommodate this during the conference. At DebConf10 in New York City, by far the highlight was Eben Moglen's vision of the FreedomBox. Negotiating the hot rickety subways was fun, the party at the NYC Resistor space was most excellent, Coney Island was hot and the water a bit yuck, zack threw a ball, the food and campus was really nice. Really enjoyed the lintian BoF, ARM discussions, shy folks, GPLv3 question time, paulproteus' comments & insights, wiki BoF, puppet BoF, derivatives BoF, Sita, astronomy rooftop, cheese, virt BoF, Libravatar, DebConf11, Brave new Multimedia World, bagels for breakfast, CUT, OpenStreetMap & lightning talks. Having my power supply die was not fun at all. Afterwards I hung out with a couple of the exhausted organisers, ate awesome vegan food and fell asleep watching a movie about dreams. One weird thing about DebConf10 was that relatively few folks used the DebConf gallery to host their photos, months later only myself and Aigars Mahinovs posted any photos there. At FOSSASIA 2010 in H Ch Minh City (HCMC) was a mini-DebConf. I arrived at the HCMC airport and was greeted by Huyen (thanks!!), one of FOSSASIA's numerous volunteers, who bundled me into a taxi bound for the speakers accommodation and pre-event meetup at The Spotted Cow Bar. The next day the conference opened at the Raffles International College and after looking at the schedule I noticed that I was to give a talk about Debian that day. Since I didn't volunteer for such a talk and had nothing prepared, the schedule took me by surprise. So shortly after an awesome lunch of Vietnamese pancakes we gathered some Debian folks and a random Fedora dude and prepared a short intro to Debian. The rest of the day the highlights were the intro, video greetings and the fonts, YaCy and HTML5 talks. The next day the Debian MiniConf began with Arne Goetje and everyone trying to get Debian Live LXDE USB keys booted on as many machines in the classroom as possible (many didn't boot). Once people started showing up we kicked off with Thomas Goirand's introduction to the breadth of Debian. Others talked about Debian pure blends, Gnuk and building community and packages. The second last session was about showing the Vietnamese folks in the room how to do l10n and translation since Debian had only one Vietnamese translator (Clytie Siddall). After manually switching keyboard layouts (seems LXDE doesn't have a GUI for that) on the English LXDE installs, the two Cambodian folks were able to do some Khmer translation too. This was a great session and it resulted in two extra Vietnamese translators joining Debian. It went over time so I didn't end up doing my presentation about package reviewing. We rushed off to a university where the random Fedora ch^Wambassador was hosting a Fedora 14 release party in a huge packed classroom. There were a lot of excited faces, interesting and advanced questions and it was in general a success. Afterwards we had some food, joined up with some other speakers and ended up in a bar in the gross tourist zone. On the final day we hung around in the Debian room, went downstairs for the group photo and final goodbyes. Later we found a place with baked goods, coffee and juices and navigated the crazy traffic to a nice local restaurant. The next morning Arne & I went to the airport, others went on a Mekong Delta tour and Jonas hung out with the organisers. I took less photos than at other events but got a few interesting ones. I avoided doing a lot of FLOSS stuff over the last year, I hope to work on some things in the coming months; I'm also planning some interesting travel and acquiring some new technological goods, more on those in some later posts.

Debian News: Who is using Debian?

Here are the Debian users who have submitted a request to appear in our website so far in this year. Please welcome them into our Project! And here are some of their reasons to choose Debian:
We have chosen Debian over other alternatives; because of its reliability and easiness of maintenance.
The decision was based on the selection of additional expandable components, availability of distribution, a regular cycle for issuing amendments, stability and support solutions for a wide range of equipment for a dedicated server solutions.
Stability is important for us.
The main reason for choosing Debian over other distributions is the package management, security, number of available packages, ease-of-use, stability, amount of quality documentation, and cost.
We choose Debian to easen the burden of system administration. Also because Debian has very well maintaned packages and for high security.
Debian is powerful and keeping originality of Linux.
We find the software that comes with Debian very useful and easy to use since we are not specialists in computer matters.
Debian is the most powerful Linux distribution! The best choice for our jobs, our servers and our lifestyle.
We chose Debian because it is stable, simple and fast to install and to use, and because it is Free Software.
We are proud to say that we use Debian/GNU Linux on more than 90% of our servers and this simply because of it s stability, security and great packaging system.
Debian offered the perfect balance between security, stability and ease of administration.
We chose Debian for its rock-solid stability, ease of installation and configuration, and awesome ability to not only run on old, second-hand hardware, but to turn that hardware into powerful production machines perfect for our needs. We also like Debian s Social Contract. None of the other options were as successful in this implementation.
It is refreshing and enjoyable to have an operating system which gives users easy access.
Thanks very much for the hard work, Webmaster Team.

Gunnar Wolf: New York at last!

I spent the past three weeks away from basically any kind of usual contact. I took a three week vacation in Argentina (Buenos Aires, Entre R os, Tucum n, Salta, Jujuy, C rdoba), got my first snow experience and enjoyed a real lot... But got completely disconnected from all of my usual activities... and responsabilities :- Anyway, yesterday afternoon I landed in New York. Arrived to Columbia around 2PM, and spent most of the day zombying around with the Debian crew. And today it starts feeling like the real job is starting. As always, there is a lot of excitement when DebConf starts. I have many items I want to work on, and most are even Debian related ;-) So, lets get work flowing!

Wouter Verhelst: LOAD

No, I'm not reverting to the commodore 64. LOAD stands for 'Linux Open Administration Days' and is a community event targetted at sysadmins. LOAD, the Linux system administrator event This being quite obvious, as I have a talk on the schedule. It'll be a repeat of my 'Debian Secrets' talk that I've also done at FOSDEM, in Essen, and in Buenos Aires. Except it will be better than it was at FOSDEM. I'll be there the whole of saturday. Not sure yet about Sunday.

Stefano Zacchiroli: RC bugs of the week - issue 25

RCBW - #25 Last (long) week has finally passed: first in Geneve visiting Gismo, then in Sierre/Crans-Montana to present a paper at SAC 2010, then back in Paris for half a day before a day in Bruxelles for the 2nd year Mancoosi project review. (And of course campaigning has always been going on ...) All went fine and I can finally relax a bit for a week-end back "home" (i.e. Paris). Regarding RCBW, it looks like that in the past 2 months I've stabilized around 3 issues per month, which makes me happy nevertheless. Without any further ado, here are this weekissue's squashes: Random points:

Next.
