Thorsten Alteholz: My Debian Activities in March 2015

FTP assistant Recently the NEW queue grew due to lots of uploads of new KDE software and several smaller node-packages. The KDE-stuff will be processed one after another, but the node-stuff seems to be rather strange. After the last discussion I was told that all those small packages can be accumulated into bigger chunks. I hope this discussion doesn t need to be repeated again Anyway, this month I marked 117 packages for accept and rejected 51 packages. Squeeze LTS This was my ninth month that I did some work for the Squeeze LTS initiative, started by Raphael Hertzog at Freexian. This month I got assigned a workload of 15.25h and I spent these hours to upload new versions of: Finally I was also able to upload the binutils package. Up to now, I got no complaints that something is not working anymore, so yeah, I seem to make it. The next big adventure will be a new upload of PHP. I already started with some patches, but it is still a good piece of work. I also uploaded update for DLA 164-1] unace security update, [DLA 168-1] konversation security update and [DLA 172-1] libextlib-ruby security update although no LTS sponsor indicated any interest. Other packages This month the severity of one bug in greylistd had been raised from normal to severe and such I had to upload a new version. Thanks to Andreas Beckmann for raising and for providing a patch. I also uploaded a new version of dict-elements and closed a bug related to reproducible builds. As I am the maintainer of libkeepalive, I got an email from Andreas Florath. He wanted to persuade me to create a package for his library libdontdie, which is rather similar to libkeepalive but has some improvements. As I promised to do some more packaging work, he didn t have to argue much and voila, there now is a new package libdontdie available. As the cooperation with him is really pleasant, I also created a package for his other project: pipexec. Donations Thanks alot to all donors, this month I got 30 in total. I really appreciate this and hope that everybody is pleased with my commitment. Don t hesitate to make suggestions for improvements.

Francois Marier: Using OpenVPN on Android Lollipop

I use my Linode VPS as a VPN endpoint for my laptop when I'm using untrusted networks and I wanted to do the same on my Android 5 (Lollipop) phone. It turns out that it's quite easy to do (doesn't require rooting your phone) and that it works very well.

Install OpenVPN Once you have installed and configured OpenVPN on the server, you need to install the OpenVPN app for Android (available both on F-Droid and Google Play). From the easy-rsa directory you created while generating the server keys, create a new keypair for your phone:
./build-key nexus6        # "nexus6" as Name, no password
and then copy the following files onto your phone:
  • ca.crt
  • nexus6.crt
  • nexus6.key
  • ta.key

Create a new VPN config If you configured your server as per my instructions, these are the settings you'll need to use on your phone: Basic:
  • LZO Compression: YES
  • Type: Certificates
  • CA Certificate: ca.crt
  • Client Certificate: nexus6.crt
  • Client Certificate Key: nexus6.key
Server list:
  • Server address: hafnarfjordur.fmarier.org
  • Port: 1194
  • Protocol: UDP
  • Custom Options: NO
Authentication/Encryption:
  • Expect TLS server certificate: YES
  • Certificate hostname check: YES
  • Remote certificate subject: server
  • Use TLS Authentication: YES
  • TLS Auth File: ta.key
  • TLS Direction: 1
  • Encryption cipher: AES-256-CBC
  • Packet authentication: SHA384 (not SHA-384)
That's it. Everything else should work with the defaults.

Rudy Godoy: No SSH for you how to fix OpenRG routers

I find interesting when faced a taken-for-granted situation, in particular in the tech world. This time s history is about an Internet ADSL connection that allows all traffic but SSH. Yes, you read it correctly. It was very bizarre confirming such event was a real-life situation. I don t claim to be a networking expert but at least I want to think I m well educated. After few minutes I ve focused my efforts on dealing with the ADSL router/modem s networking configuration. The device is provided by Movistar (formerly Telefonica) and it runs OpenRG. I ve discovered that other people have experienced the same issue and what Movistar did was basically replacing the device. Of course the problem is gone after that. So, this post is dedicated to those who don t give up. Following the steps below will allow SSH outbound traffic for a OpenRG-based device. OpenRG device specs
Software Version: 6.0.18.1.110.1.52 Upgrade
Release Date: Oct 7 2014
Diagnostic When you do the command below, it shows nothing but timeout. Even when you SSH the router it doesn t establish connection to it.
ssh -vv host.somewhere.com
Solution Change router s SSH service port. This step will allow you to access the console-based configuration for the router (since I haven t found any way to do the steps described below from the web management interface). To do so, go to System > Management > SSH. Update the service port to something else than 22, for instance 2222.
OpenRG SSH service configuration

OpenRG SSH service configuration

Connect to the SSH interface Once you have changed the SSH service port, you can access it from a SSH client.
ssh -p 2222 admin@192.168.1.1
admin@192.168.1.1's password: 
OpenRG>
Once you have the console prompt, issue the following commands to allow SSH outbound traffic coming from the LAN and Wifi networks. After the last command, which saves and updates the device s configuration, you should be able to do SSH from any computer in your network to the Internet (thanks to tips from inkhorn).
OpenRG> conf set fw/policy/0/chain/fw_br0_in/rule/0/enabled 0
Returned 0
OpenRG> conf set fw/policy/0/chain/fw_br1_in/rule/0/enabled 0

Ben Hutchings: Debian LTS work, March 2015

This was my fourth month working on Debian LTS. I was assigned 14.5 hours by Freexian's Debian LTS initiative, but I only worked 11.5 as I had a week's holiday and then was ill for part of this week. eglibc My first task was to complete the eglibc update that I began at the end of February. There were a few unexpected failures in the regression test suite, but on inspection these turned out to be quirks of the build environment: With those changes, the regression test results are the same as for previous package versions. (There is still one 'unexpected' failure, but I didn't investigate because it is not a regression within squeeze.) I reviewed the backported patches again to check as well as I could that they did not depend on other upstream changes, and they did not seem to. I also received positive feedback from further testing - I can't find the message now, but I think it was that the Univention application test suite passed with the updated eglibc package installed. With that confirmation and no regressions reported, I uploaded eglibc 2.11.3-4+deb6u5 and issued DLA 165-1. freetype A large number of vulnerabilities in font file parsing in Freetype were reported by Mateusz Jurczyk. I think these were less critical in squeeze than in wheezy, because while current web browsers use Freetype to render untrusted 'web fonts' we don't support any web browsers in squeeze LTS. But it seemed like they ought to be fixed anyway, and it was not too hard to backport the patches included in the wheezy security update. Freetype doesn't have a regression test suite and I didn't have samples of the broken fonts, so I came up with some ad hoc tests for regressions. I viewed several of each of the affected font formats with the ftview demo application. I then wrote a script to match up the dependencies of a package (in this case, libfreetype6) with those used by Freexian's customers; the top results were fontconfig, xfonts-utils and imagemagick. So I ran some basic tests against each of the affected formats with each of these (fc-list, mkfontscale, and the simple text label recipe for ImageMagick) and found no regression. Uploaded freetype 2.4.2-2.1+squeeze5 and issued DLA 185-1.

Michal Čihař: GSoC 2015 applications for phpMyAdmin

As usual, I look at the application stats for phpMyAdmin just after student application period of Google Summer of Code is over. First of all we got way more proposals than in last years, but also number of bogus proposals went up (you can see them as ignored in the chart). Same as in past years, people leave the submission to the last moment, even though we encourage them to submit early so that they can adjust the application based on our feedback. But still we got more than half of the proposals in last three days. Number of applications over time Anyway we're just working on evaluation and will finalize it in upcoming days. Of course you will know the results from Google on April 27th. PS: You can compare to our 2014, 2013 and 2012 numbers.

Holger Levsen: 20150401-reproducible-jessie

Testing jessie for reproducibility or "here, have some 8 cores and 25 GB RAM extra..." So three weeks ago it occurred to me that it would be useful to test the reproducibility of Jessie too (until then we only tested unstable and experimental), as this will give us a nice data point to compare future developments against and also because we wanted to test "testing" in future anyway, so we could as well start while "testing" is still jessie... (because then we will have to test less once stretch development has started, as in the beginning stretch will be jessie anyway.) Quite quickly I then realized that building all packages twice on the current, quite heavily loaded jenkins.debian.net machine, would take 4-6 weeks and that it might well happen that we'll release Jessie before this has finished. (And I do want a Jessie release rather sooner than later!) So I've asked Profitbricks, who have been sponsoring the jenkins.debian.net setup since October 2012, for some more resources temporarily, and once again they quickly helped out and the next day I could add eight cores and 25 GB of RAM to the existing VM, for a total of 23 Cores and 75 GB RAM. So currently jenkins.d.n runs eight reproducible build jobs simultaneously, each of them is pbuilding packages in tmpfs in RAM. Thus these builds are really fast: for small packages without additional build depends build times as low as 40 seconds can be seen, which doesn't sound impressive at first, but this includes the source download and building twice and it includes untar'ing the base.tgz twice as well as running debbindiff on the resulting binary packages. (And all this is while quite many other jobs continue to hammer the machine as well.) (BTW: I doubt using LVM snapshots is faster then running this in tmpfs, but if you think LVM is faster I'd be curious to see some numbers.) Interestingly this rebuild also discovered a rather unexpected result as we found an RC bug in jessie, which caused build failures for >20 packages: "#781076 cdbs: perlmodule-vars.mk LDDLFLAGS quoting problem". And then there were some unexpected but really expectable results: testing turned out to "only" give reproducible results for 79.4% of all packages in main, while unstable has 82.6% reproducible packages. This was unexpected, as our (few) fixed packages in our repo are also used for testing testing and as testing is smaller than sid, I at first believed the reproducible percentage should be higher, as testing has 1000 packages less. So why was the lower percentage to be expected? This is due to two factors: since FOSDEM we have introduced a number of new variations for the second build, that is we now build with a.) a different domainname, b.) with a different umask, c.) a different timezone and d.) a different kernel version (using 'linux64 --uname-2.6'). And secondly, most packages in sid haven't been rebuild since FOSDEM. Thus we'll now reschedule all packages in testing which are unreproducible in unstable, which should decrease the current reproducibility of sid a bit... For those wondering about the 622 packages failing to build in testing: at least 453 are due to our test setup, categorized in (currently) three issues: timestamps_from_cpp_macros, ftbfs_werror_equals and ocaml_configure_not_as_root. The ones in this third issue category are rather trivial to fix, so this leaves 622-453=169 minus those fixed by #781076, so roughly 150 packeges which fail to build in our setup which need to be investigated... And for those wondering about other missing variations, there is at least one big one missing: changing the build date. Current guestimate is that this will make 1-2000 packages unreprdoucible again but we'll only know for sure once we tested them. So I would like to once again thank Profitbricks for supporting jenkins.d.n in the last 2.5 years and making reproducible.d.n possible so smoothly. Being able to painlessly add more resources when we needed them was incredible useful and I hope we can count on their support in the future. (I have some more ideas how to burn resources usefully in future. Stay tuned and btw, if you know how to put more hours in the day, please do tell me. ;) And, of course: thanks for your work on Debian, no matter whether you've been working on Jessie, reproducibility or something totally different! To finish this post I'd like to remind everyone that currently all this is just about the prospects of reproducible builds for Debian. Debian is not 80% reproducible yet - but it easily could be! And I certainly hope it will be "soon", and hopefully "soon" will only mean a few months. We will rebuild and see.

Joey Hess: I am ArchiveTeam

This seems as good a day as any to mention that I am a founding member of ArchiveTeam. ArchiveTeam logo Way back, when Geocities was closing down, I was one of a small rag-tag group who saved a copy of most of it. That snapshot has since generated more publicity than most other projects I've worked on. I've heard many heartwarning stories of it being the only remaining copy of baby pictures and writings of deceased friends, and so on. It's even been the subject of serious academic study as outlined in this talk, which is pretty awesome. Jason Scott in full stage regalia I'm happy to let this guy be the public face of ArchiveTeam in internet meme-land. It's a 0.1% project for me, and has grown into a well-oiled machine, albeit one that shouldn't need to exist. I only get involved these days when there's another crazy internet silo fire drill and/or I'm bored. (Rumors of me being the hand model for ArchiveTeam are, however, unsubstantiated.) Relevant XKCD

Benjamin Mako Hill: RomancR: The Future of the Sharing-Your-Bed Economy

romancer_logo Today, Aaron Shaw and I are pleased to announce a new startup. The startup is based around an app we are building called RomancR that will bring the sharing economy directly into your bedrooms and romantic lives. When launched, RomancR will bring the kind of market-driven convenience and efficiency that Uber has brought to ride sharing, and that AirBnB has brought to room sharing, directly into the most frustrating and inefficient domain of our personal lives. RomancR is Uber for romance and sex. Here s how it will work: Of course, there are many existing applications like Tinder and Grindr that help facilitate romance, dating, and hookups. Unfortunately, each of these still relies on old-fashion intrinsic ways of motivating people to participate in romantic endeavors. The sharing economy has shown us that systems that rely on these non-monetary motivations are ineffective and limiting! For example, many altruistic and socially-driven ride-sharing systems existed on platforms like Craigslist or Ridejoy before Uber. Similarly, volunteer-based communities like Couchsurfing and Hospitality Club existed for many years before AirBnB. None of those older systems took off in the way that their sharing economy counterparts were able to! The reason that Uber and AirBnB exploded where previous efforts stalled is that this new generation of sharing economy startups brings the power of markets to bear on the problems they are trying to solve. Money both encourages more people to participate in providing a service and also makes it socially easier for people to take that service up without feeling like they are socially in debt to the person providing the service for free. The result has been more reliable and effective systems for proving rides and rooms! The reason that the sharing economy works, fundamentally, is that it has nothing to do with sharing at all! Systems that rely on people s social desire to share without money projects like Couchsurfing are relics of the previous century. RomancR, which we plan to launch later this year, will bring the power and efficiency of markets to our romantic lives. You will leave your pitiful dating life where it belongs in the dustbin of history! Go beyond antiquated non-market systems for finding lovers. Why should we rely on people s fickle sense of taste and attractiveness, their complicated ideas of interpersonal compatibility, or their sense of altruism, when we can rely on the power of prices? With RomancR, we won t have to! Note: Thanks to Yochai Benkler whose example of how leaving a $100 bill on the bedside table of a person with whom you spent the night can change the nature of the a romantic interaction inspired the idea for this startup.

Raphael Geissert: Special guest for the Lyon minidebconf, 2015

It appears that this year's MiniDebconf in Lyon, France is going to have a very special guest. After enjoying so much the Q&A held at Debconf14, Linus Torvalds has decided to make a quick detour from a trip to Europe to bring the opportunity for another session with the Debian community.

The event has yet to appear in the MiniDebconf agenda. Rumor has it that the hurds of fans that tend to attend his events pose a logistics and safety challenge, reason why the event might only appear in the agenda a couple of days before the event.
Lyon being such an easy place to get by train, flight, car, and even by boat, it is understandable and should be expected that a great number of people attend the minidebconf only for his very session.

If you have not yet registered, I'd recommend you to do so now and to book your travel and accommodation ASAP, before everything is overpriced due to high demand.

See you in ten days!

P.S. kudos to the organizers!

Raphaël Hertzog: My Free Software Activities in March 2015

My monthly report covers a large part of what I have been doing in the free software world. I write it for my donators (thanks to them!) but also for the wider Debian community because it can give ideas to newcomers and it s one of the best ways to find volunteers to work with me on projects that matter to me. Debian LTS This month I have been paid to work 15.25 hours on Debian LTS. In that time I did the following: That s it for the paid work. But still about LTS, I proposed two events for Debconf 15: A Debian LTS logoIn my last Freexian LTS report, I mentioned briefly that it would be nice to have a logo for the LTS project. Shortly after I got a first logo prepared by Damien Escoffier and a few more followed: they are available on a wiki page (and the logo you see above is from him!). Following a suggestion of Paul Wise, I registered the logo request on another wiki page dedicated to artwork requests. That kind of collaboration is awesome! Thanks to all the artists involved in Debian. Debian packaging Django. This month has seen no less than 3 upstream point releases packaged for Debian (1.7.5, 1.7.6 and 1.7.7) and they have been accepted by the release team into Jessie. I m pleased with this tolerance as I have argued the case for it multiple times in the past given the sane upstream release policy (bugfix only in a given released branch). Python code analysis. I discovered a few months ago a tool combining the power of multiple Python code analysis tools: it s prospector. I just filed a Request for Package for it (see #781165) and someone already volunteered to package it, yay \o/ update-rc.d and systemd. While working on a Kali version based on Jessie, I got hit by what boils down to a poor interaction between systemd and update-rc.d (see #746580) and after some exchanges with other affected users I raised the severity to serious as we really ought to do something about it before release. I also opened #781155 on openbsd-inetd as its usage of inetd.service instead of openbsd-inetd.service (which is only provided as a symlink to the former) leads to multiple small issues. Misc Debian France. The general assembly is over and the new board elected its new president: it s now official, I m no longer Debian France s president. Good luck to Nicolas Dandrimont who took on this responsibility. Salt s openssh formula. I improved salt s openssh formula to make it possible to manage the /etc/ssh/ssh_known_hosts file referencing the public SSH keys of other managed minions. Tendenci.com. I was looking for a free software solution to handle membership management of a large NPO and I discovered Tendenci. It looked very interesting feature wise and written with a language/framework that I enjoy (Python/Django). But while it s free software, there s no community at all. The company that wrote it released it under a free software license and it really looks like that they did intend to build a community but they failed at it. When I looked their development forums were web-based and mostly empty with only initial discussion of the current developers and no reply from anybody there s also no mention of an IRC channel or a mailing list. I sent them a mail to see what kind of collaboration we could expect if we opted for their software and got no reply. A pity, really. What free software membership management solution would you use when you have more than 10000 members to handle and when you want to use the underlying database to offer SSO authentication to multiple external services? Thanks See you next month for a new summary of my activities.

Benjamin Mako Hill: More Community Data Science Workshops

Pictures from the CDSW sessions in Spring 2014Pictures from the CDSW sessions in Spring 2014
After two successful rounds in 2014, I m helping put on another round of the Community Data Science Workshops. Last year, our 40+ volunteer mentorss taught more than 150 absolute beginners the basics of programming in Python, data collection from web APIs, and tools for data analysis and visualization and we re still in the process of improving our curriculum and scaling up. Once again, the workshops will be totally free of charge and open to anybody. Once again, they will be possible through the generous participation of a small army of volunteer mentors. We ll be meeting for four sessions over three weekends: If you re interested in attending, or interested in volunteering as mentor, you can go to the information and registration page for the current round of workshops and sign up before April 3rd.

Zlatan Todori : Fruit flies like a banana

I started working for Valve as a community manager.

Zlatan Todori : Interviews with FLOSS developers: Francesca Ciceri

Debian and FLOSS community don't only occupy coding developers. They occupy people who write news, who talk about FLOSS, who help on booths and conferences, who create artistic forms of the community and so many others that contribute in countless ways. A lady, that is doing many of that is Francesca Ciceri, known in Debian as MadameZou. She is non-packaging Debian Developer, a fearless warrior for diversity and a zombie fan. Although it sounds intimidating, she is deep caring and great human being. So, what has MadaZou to tell us? Picture of MadameZou Who are you? My name is Francesca and I'm totally flattered by your intro. The fearless warrior part may be a bit exaggerated, though. What have you done and what are you currently working on in FLOSS world? I've been a Debian contributor since late 2009. My journey in Debian has touched several non-coding areas: from translation to publicity, from videoteam to www. I've been one of the www.debian.org webmasters for a while, a press officer for the Project as well as an editor for DPN. I've dabbled a bit in font packaging, and nowadays I'm mostly working as a Front Desk member. Setup of your main machine? Wow, that's an intimate question! Lenovo Thinkpad, Debian testing. Describe your current most memorable situation as FLOSS member? Oh, there are a few. One awesome, tiring and very satisfying moment was during the release of Squeeze: I was member of the publicity and the www teams at the time, and we had to pull a 10 hours of team work to put everything in place. It was terrible and exciting at the same time. I shudder to think at the amount of work required from ftpmaster and release team during the release. Another awesome moment was my first Debconf: I was so overwhelmed by the sense of belonging in finally meeting all these people I've been worked remotely for so long, and embarassed by my poor English skills, and overall happy for just being there... If you are a Debian contributor I really encourage you to participate to Debian events, be they small and local or as big as DebConf: it really is like finally meeting family. Some memorable moments from Debian conferences? During DC11, the late nights with the "corridor cabal" in the hotel, chatting about everything. A group expedition to watch shooting stars in the middle of nowhere, during DC13. And a very memorable videoteam session: it was my first time directing and everything that could go wrong, went wrong (including the speaker deciding to take a walk outside the room, to demonstrate something, out of the cameras range). It was a disaster, but also fun: at the end of it, all the video crew was literally in stitches. But there are many awesome moments, almost too many to recall. Each conference is precious on that regard: for me the socializing part is extremely important, it's what cements relationships and help remote work go smoothly, and gives you motivation to volunteer in tasks that sometimes are not exactly fun. You are known as Front Desk member for DebConf's - what work does it occupy and why do you enjoy doing it? I'm not really a member of the team: just one of Nattie's minions! You had been also part of DebConf Video team - care to share insights into video team work and benefits it provides to Debian Project? The video team work is extremely important: it makes possible for people not attending to follow the conference, providing both live streaming and recording of all talks. I may be biased, but I think that DebConf video coverage and the high quality of the final recordings are unrivaled among FLOSS conferences - especially since it's all volunteer work and most of us aren't professional in the field. During the conference we take shifts in filming the various talks - for each talk we need approximately 4 volunteers: two camera operators, a sound mixer and the director. After the recording, comes the boring part: reviewing, cutting and sometimes editing the videos. It's a long process and during the conference, you can sometimes spot the videoteam members doing it at night in the hacklab, exhausted after a full day of filming. And then, the videos are finally ready to be uploaded, for your viewing pleasure. During the last years this process has become faster thanks to the commitment of many volunteers, so that now you have to wait only few days, sometimes a week, after the end of the conference to be able to watch the videos. I personally love to contribute to the videoteam: you get to play with all that awesome gear and you actually make a difference for all the people who cannot attend in person. You are also non-packaging Debian Developer - how does that feel like? Feels awesome! The mere fact that the Debian Project decided - in 2009 via a GR - to recognize the many volunteers who contribute without doing packaging work is a great show of inclusiveness, in my opinion. In a big project like Debian just packaging software is not enough: the final result relies heavily on translators, sysadmins, webmasters, publicity people, event organizers and volunteers, graphic artists, etc. It's only fair that these contributions are deemed as valuable as the packaging, and to give an official status to those people. I was one of the firsts non-uploading DD, four years ago, and for a long time it was just really an handful of us. In the last year I've seen many others applying for the role and that makes me really happy: it means that finally the contributors have realized that they deserve to be an official part of Debian and to have "citizenship rights" in the project. You were the leading energy on Debian's diversity statement - what gave you the energy to drive into it? It seemed the logical conclusion of the extremely important work that Debian Women had done in the past. When I first joined Debian, in 2009, as a contributor, I was really surprised to find a friendly community and to not be discriminated on account of my gender or my lack of coding skills. I may have been just lucky, landing in particularly friendly teams, but my impression is that the project has been slowly but unequivocally changed by the work of Debian Women, who raised first the need for inclusiveness and the awareness about the gender problem in Debian. I don't remember exactly how I stumbled upon the fact that Debian didn't have a Diversity Statement, but at first I was very surprised by it. I asked zack (Stefano Zacchiroli), who was DPL at the time, and he encouraged me to start a public discussion about it, sending out a draft - and helped me all the way along the process. It took some back and forth in the debian-project mailing list, but the only thing needed was actually just someone to start the process and try to poke the discussion when it stalled - the main blocker was actually about the wording of the statement. I learned a great deal from that experience, and I think it changed completely my approach in things like online discussions and general communication within the project. At the end of the day, what I took from that is a deep respect for who participated and the realization that constructive criticism does require certainly a lot of work for all parts involved, but can happen. As for the statement in itself: these things are as good as you keep them alive with best practices, but I think that are better stated explicitly rather than being left unsaid. You are involved also with another Front Desk, the Debian's one which is involved with Debian's New Members process - what are tasks of that FD and how rewarding is the work on it? The Debian Front Desk is the team that runs the New Members process: we receive the applications, we assign the applicant a manager, and we verify the final report. In the last years the workflow has been simplified a lot by the re-design of the nm.debian.org website, but it's important to keep things running smoothly so that applicants don't have too lenghty processes or to wait too much before being assigned a manager. I've been doing it for a less more than a month, but it's really satisfying to usher people toward DDship! So this is how I feel everytime I send a report over to DAM for an applicant to be accepted as new Debian Developer: Crazy pic How do you see future of Debian development? Difficult to say. What I can say is that I'm pretty sure that, whatever the technical direction we'll take, Debian will remain focused on excellence and freedom. What are your future plans in Debian, what would you like to work on? Definetely bug wrangling: it's one of the thing I do best and I've not had a chance to do that extensively for Debian yet. Why should developers and users join Debian community? What makes Debian a great and happy place? We are awesome, that's why. We are strongly committed to our Social Contract and to users freedom, we are steadily improving our communication style and trying to be as inclusive as possible. Most of the people I know in Debian are perfectionists and outright brilliant in what they do. Joining Debian means working hard on something you believe, identifying with a whole project, meeting lots of wonderful people and learning new things. It ca be at times frustrating and exhausting, but it's totally worth it. You have been involved in Mozilla as part of OPW - care to share insights into Mozilla, what have you done and compare it to Debian? That has been a very good experience: it meant have the chance to peek into another community, learn about their tools and workflow and contribute in different ways. I was an intern for the Firefox QA team and their work span from setting up specific test and automated checks on the three version of Firefox (Stable, Aurora, Nightly) to general bug triaging. My main job was bug wrangling and I loved the fact that I was a sort of intermediary between developers and users, someone who spoke both languages and could help them work together. As for the comparison, Mozilla is surely more diverse than Debian: both in contributors and users. I'm not only talking demographic, here, but also what tools and systems are used, what kind of skills people have, etc. That meant reach some compromises with myself over little things: like having to install a proprietary tool used for the team meetings (and getting crazy in order to make it work with Debian) or communicating more on IRC than on mailing lists. But those are pretty much the challenges you have to face whenever you go out of your comfort zone . You are also volunteer of the Organization for Transformative Works - what is it, what work do you do and care to share some interesting stuff? OTW is a non profit organization to preserve fan history and cultures, created by fans. Its work range from legal advocacy and lobbying for fair use and copyright related issues, developing and maintaining AO3 -- a huge fanwork archive based on open-source software --, to the production of a peer-reviewed academic journal about fanworks. I'm an avid fanfiction reader and writer, and joining the OTW volunteers seemed a good way to give back to the community - in true Debian fashion . As a volunteer, I work for the Translation Committee: we are more than a hundred people - divided in several language teams - translating the OTW website, the interface of AO3 archive, newsletter, announcements and news posts. We have a orga-wide diversity statement, training for recruits, an ever growing set of procedures to smooth our workflow, monthly meetings and movie nights. It's an awesome group to work with. I'm deeply invested in this kind of work: both for the awesomeness of OTW people and for the big role that fandom and fanworks have in my life. What I find amazing is that the same concept we - as in the FLOSS ecosystem - apply to software can be applied to cultural production: taking a piece of art you love and expand, remix, explore it. Just for the fun of it. Protect and encourage the right to play in this cultural sandbox is IMO essential for our society. Most of the participants in the fandom come from marginalised group or minorities whose point of view is usually not part of the mainstream narratives. This makes the act of writing, remixing and re-interpreting a story not only a creative exercise but a revolutionary one. As Elizabeth Minkel says: "My preferred explanation is the idea that the vast majority of what we watch is from the male perspective authored, directed, and filmed by men, and mostly straight white men at that. Fan fiction gives women and other marginalised groups the chance to subvert that perspective, to fracture a story and recast it in her own way." In other words, "fandom is about putting debate and conversation back into an artistic process". On a personal side - you do a lot of DIY, handmade works. What have you done, what joy does it bring to you and share with us a picture of it? I like to think that the hacker in me morphs in a maker whenever I can actually manipulate stuff. The urge to explore ways of doing things, of create and change is probably the same. I've been blessed with curiousity and craftiness and I love to learn new DIY techniques: I cannot describe it, really, but if I don't make something for a while I actually feel antsy. I need to create stuff. Nowadays, I'm mostly designing and sewing clothes - preferably reproductions of dresses from the 40s and the 50s - and I'm trying to make a living of that. It's a nice challenge: there's a lot of research involved, as I always try to be historically accurate in design, sewing tecniques and material, and many hours of careful attention to details. I'm right in the process of make photoshoots for most of my period stuff, so I'll share with you something different: a t-shirt refashion done with the DebConf11 t-shirt!

Niels Thykier: Jessie is coming the 2015-04-25

Indeed, we settled on a release date for Jessie and pretty quick too. I sent out a poll on the 28th of March and yesterday, it was clear that the 25th of April was our release date. :) With that said, we still have some items left that needs to be done.

Laura Arjona: Upgrading my home server (HP Microserver N54L G7) to Debian Jessie

Note: this is a long overdue post. I upgraded some months ago but I promised myself to blog about my selfhosting adventures, so here you are.
You may know the story TL;DR After searching a bit for information about my problem and not finding anything helpful, I began to think that maybe upgrading to Jessie could fix it (recent versions of kernel and cryptsetup ). And the Jessie freeze was almost there, and I also thought that trying to make my MediaGoblin work in Jessie now that I still didn t upload lots of content, would be a nice idea And, I wanted to feel the adventure! Whatever. I decided to upgrade to Jessie. This is the glory of free software at home : you only waste your time (and probably not, because you can learn something, at least, what not to do). Upgrading my system to Jessie, and making it boot! I changed sources.list, updated, did a safe-upgrade, and then upgrade. Then reboot and the system didn t boot. What happened? I m not sure, everything looked ok during the upgrade But now, my system even was not asking for the passphrase to unlock the encrypted disk. It was trying to access the physical volume group as if it was in an unencrypted disk, and so, failing. The boot process left me in a initramfs console in which I didn t know what to do. I asked help from @luisgf, the system administrator of mipump.es (a Pump.io public server) and mijabber.es (an XMPP public server). We met via XMPP and with my thinking aloud and his patient listening and advice, we solved the problem, as you will see: I tried to boot my rescue system (a complete system installed in different partitions in a different disk) and it booted. I tried then to manually unencrypt the encrypted disk (cryptsetup luksopen /dev/xxx), and it worked, and I could list the volume group and the volumes, and activate them, and mount the partitions. Yay! my (few) data was safe. I rebooted and in the initramfs console I tried to do the same, but cryptsetup was not present in my initramfs. Then I tried to boot in the old Wheezy kernel: it didn t asked for the passphrase to unencrypt the disk, but in that initramfs console, cryptsetup was working well. So after manually unencrypt the system, activate the volumes and mount the partitions, I could exit the console and the system was booting #oleole! So, how to tell the boot process to ask for the encryption password? Maybe reinstalling the kernel was enough I tried to reinstall the 3.16 kernel package. It (re)generated /boot/initrd.img-3.16.0-4-amd64 and then I restarted the system, and the problem was solved. It seems that the first time, the kernel didn t generate the initrd image correctly, and I didn t notice about that. Well, problem solved. My system was booting again! No other boot problems and Jessie seemed to run perfectly. Thanks @luisgf for your help! In addition to that, since then, my password has been accepted in every reboot, so it seems that the original problem is also gone. A note on systemd After all the noise of last months, I was a bit afraid that any of the different services that run on my system would not start with the migration to systemd.
I had no special tweaks, just two handmade init scripts (for MediaGoblin, and for NoIP), but I didn t write them myself (I just searched about systemd init scripts for the corresponding services), so if it was any problem there I was not sure that I could solve it. However, everything worked fine after the migration. Thanks Debian hackers to make this transition as smooth as possible! Reinstalling MediaGoblin My MediaGoblin was not working, and I was not sure why. Maybe it was just that I need to tune nginx or whatever, after the upgrade But I was not going to spend time trying to know what part of the stack was the culprit, and my MediaGoblin sites were almost empty So I decided to follow again the documentation and reinstall (maybe update would be enough, who knows). I reused the Debian user(s), the PostgreSQL users and databases, and the .ini files and nginx configuration files. So it was quick, and it worked. Updating Jessie I have updated my Jessie system several times since then (kernel updates, OpenSSL, PostgreSQL, and other security updates and RC bugs fixes, with the corresponding reboots or service restarts) and I didn t experience the cryptsetup problem again. The system is working perfectly. I m very happy. Using dropbear to remotely provide the cryptsetup password The last thing I made in my home server was setting up dropbear so I can remotely provide the encryption password, and then, remotely reboot my system. I followed this guide and it worked like a charm. Some small annoyances and TODO list

A note about RAID Some people commented about the benefits of the software RAID (mainly, not to depend on a particular, proprietary firmware, what happens if my motherboard dies and I cannot find a compatible replacement?). Currenty I have a RAID 1 (mirror) using the capabilities of the motherboard. The problem is that, frankly, I am not sure about how to migrate the current setup (BIOS RAID + cryptsetup + LVM + partitions) to the new setup (software RAID + cryptsetup + LVM + partitions, or better other order?). As you see, lots of things to read/think/try I hope I can find time for my home server more often! Comments? You can comment on this pump.io thread.

Jonathan McDowell: Shipping my belongings across the globe

I previously wrote about tracking a ship around the world, but never followed up with the practical details involved with shipping my life from the San Francisco Bay Area back to Belfast. So here they are, in the hope they provide a useful data point for anyone considering a similar move. Firstly, move out. I was in a one bedroom apartment in Fremont, CA. At the time I was leaving the US I didn t have anywhere for my belongs to go - the hope was I d be back in the Bay Area, but there was a reasonable chance I was going to end up in Belfast or somewhere in England. So on January 24th 2014 I had my all of my belongings moved out and put into storage, pending some information about where I might be longer term. When I say all of my belongings I mean that; I took 2 suitcases and everything else went into storage. That means all the furniture for probably a 2 bed apartment (I d moved out of somewhere a bit larger) - the US doesn t really seem to go in for the concept of a furnished lease the same way as the UK does. I had deliberately picked a moving company that could handle the move out, the storage and the (potential) shipping. They handed off to a 3rd party for the far end bit, but that was to be expected. Having only one contact to deal with throughout the process really helped. Fast forward 8 months and on September 21st I contacted my storage company to ask about getting some sort of rough shipping quote and timescales to Belfast. The estimate came back as around a 4-6 week shipping time, which was a lot faster than I was expecting. However it turned out this was the slow option. On October 27th (delay largely due to waiting for confirmation of when I d definitely have keys on the new place) I gave the go ahead. Container pickup (I ended up with exclusive use of a 20ft container - not quite full, but not worth part shipment) from the storage location was originally due on November 7th. Various delays at the Port of Oakland meant this didn t happen until November 17th. It then sat in Oakland until December 2nd. At that point the ETA into Southampton was January 8th. Various other delays, including a week off the coast of LA (yay West Coast Port Backups) meant that the ship finally arrived in Southampton on January 13th. It then had to get to Belfast and clear customs. On January 22nd 2015, 2 days shy of a year since I d seen them, my belongings and I were reunited. So, on the face of it, the actual time on the ship was only slightly over 6 weeks, but all of the extra bits meant that the total time from Ship it to I have it was nearly 3 months. Which to be honest is more like what I was expecting. The lesson: don t forget to factor in delays at every stage. The relocation cost in the region of US$8000. It was more than I d expected, but far cheaper than the cost of buying all my furniture again (plus the fact there were various things I couldn t easily replace that were in storage). That cost didn t cover the initial move into storage or the storage fees - it covered taking things out, packing them up for shipment and everything after that. Including delivery to a (UK) 3rd floor apartment at the far end and insurance. It s important to note that I d included this detail before shipment - the quote specifically mentioned it, which was useful when the local end tried to levy an additional charge for the 3rd floor aspect. They were fine once I showed them the quote as including that detail. Getting an entire apartment worth of things I hadn t seen in so long really did feel a bit like a second Christmas. I d forgotten a lot of the things I had, and it was lovely to basically get a home in a container delivered.
