As of yesterday, I am the new maintainer of pristine-tar. As it is the case for most of Joey Hess’ creations, it is an extremely useful tool, and used in a very large number of Debian packages which are maintained in git.
My first upload was most of a terrain recognition nature: I did some housekeeping tasks, such as making the build idempotent and making sure all binaries are built with security hardening flags, and wrote a few automated test cases to serve as build-time and run-time regression test suite. No functional changes have been made.
As Joey explained when he orphaned it, there are a few technical challenges involved in making sure pristine-tar stays useful in the future. Although I did read some of the code, I am not particularly familiar with the internals yet, and will be more than happy to get co-maintainers. If you are interested, please get in touch. The source git repository is right there.
Debian Ruby Sprint 2016 - day 5: More Reproducible Builds, Retrospective, and A Little Bit of Tourism5 de Março de 2016, 13:21
Earlier today I was made aware by Holger of the results of our reproducibility efforts during the sprint. I would like to thank Lunar for pinging us about the issue, and Holger for pointing me to updated results. The figure below depicts a stacked area chart where the X axis is time and the green area is reproducible packages. Red is packages that fail to build, and Orange are unreproducible packages
I was able to book accommodation for the sprint attendees very close to both my place and the sprint venue, what was very useful but also had this downside of them not being able to see much of city. As the final day of the sprint was getting closer, we decided to have a different lunch to allow them to see one of the most famous local landmarks, the botanical gardens.
So we headed down to the botanical gardens, grabbed a few items for lunch at the park coffee shop, and set out to visit this very beautiful place. I have to say that there is the place were I usually take every visitor I have. We were joined by Gioavani who had just arrived for the the MiniDebconf on the following weekend.
The final lists of accomplishments of the day was again very impressive

- ScottK has removed ruby2.1 from unstable!
By the end of the afternoon I asked everyone to fill out a simple retrospective list, what we can use later to make future sprints better and better. Below are the results we got.
What was good:
- restricted room hours actually made for a nice rhythm (did not apply for a long time…)
- very good food
- very cheap food!
- longer period makes the effort of travel more worthwhile
- many participants and longer sprint than usual allowing more work to be done
- good preparation with clear goals, make the sprint usefull
- patience with the less experienced participants
- RFS very fast
- Antônio is an excellent host
- You all are so helpful
- great dinners
What could be better:
- room too close to the street, too much vehicle noise, but sometimes nice music
- more coffee ^W meat
- could know more portugues so ordering food would have been easier
- debian infra could have not been down during the sprint
The night ended at Bar do Alemão (“The German’s Bar”). Both their beer and their food are very good, but I don’t have enough elements to vouch for their authenticity. :) We were joined by Giovani (who we also met earlier in the botanic gardens), and by Paulo and Daniel who are organizing the MiniDebconf.
And that is the end of this year’s Debian Ruby team sprint. I hope we do it all over again next year.
As the day 4 of the Debian Ruby team sprint in Curitiba unfolded, we have now fixed a total of more than 70 build failure bugs, managed to almost finish the Ruby 2.3 transition to be good to migrate into testing, and bootstrapped some documentation that will help new contributors get up to speed with Ruby packaging faster.
We have also requested the removal of several packages that are either severely outdated, abandoned upstream, beyond repair, utterly wrong, or in some cases, all of the above.
The full list of work items finished yesterday is:

We also managed to flirt with 2 capital sins. For those who care about these things, which I don’t (but I still care about you), I guess 2 out of 7 still means we are good? :-)
I few people that I will not name complained that they hadn’t had enough steak on the previous night, so we set out to visit a traditional all-you-can-eat Brazilian steakhouse (“churrascaria”). I made a reservation at Jardins Grill and there you have gluttony. I am pretty sure that “not enough steak” wasn’t an issue last night. You can see how happy, despite being full to almost the point of being sick, everyone was.
A disjunct set of people, who I will also not name, were very disappointed to find out that the ruby-tinder package has absolutely nothing to do with Tinder but were still very active on the later. Maybe Friday night we will have to split the group into a lust-free family party and a Tinder party.
Debian Ruby Sprint 2016 - day 3: Ruby 2.3 in unstable, Reproducible Builds, and Data Structures for Dinner Booths3 de Março de 2016, 10:42
Day 3 was again a full of useful work. Since the beginning of the sprint, we were able to fix more than 50 FTBFS¹ bugs, alongside general quality improvements in the packages.
¹ in the Debian jargon, FTBFS means that a package “fails to build from source”, which in Debian is a critical bug because users need to be able to produce binary packages from their source code to fully exercise the free software principles.
An important milestone that was also achieved on day 3 was the upload of ruby-defaults 1:2.3.0+1, making
ruby2.3 the new default version of Ruby. That is the version that will shipped in the next Debian release, codenamed stretch. This is the culmination of a joint effort between the Ruby team and Debian Release Team that involves rebuilding a little more than 130 packages that use the Ruby C API to make sure everything will just work on upgrades, both from the previous stable release, and from earlier snapshots of the current development release.
Another small change that will have a big impact for Debian and for free software was an improvement to gem2deb that fixes a reproducibility issue in Ruby packages and will help currently more than 100 Ruby packages become reproducible.
The full list of items that have been worked on is this:
- sponsor ruby-github-linguist. Closes: #815908. Thanks balasankar

The day ended at Outback, where we had an amount of beer that led us to formulate what we will now call the One-Sided Dinner Booth Problem.
In a party arranged like above, when the people closest to wall need to go alleviate themselves of some beer, you basically have to perform a removal from the bottom of a stack, which requires popping all the elements at the top. When they come back, you have to options:
- place them back at their original position, in which case
- the people who stayed have to either stay standing or get up all over again (not sure what is worse)
- the odds are that the next person to leave will require less effort from the others
- shift everyone to places against the wall and place the one coming back at the very end of the bench away from the wall, in which case
- the people who stayed are perhaps less annoyed, but you have to rearrange plates and pints
- it is less likely that the next time will require less effort from the others
The One-Sided Dinner Booth Problem is finding the optimal data structure and algorithm for this situation. It is postulated that this is an NP-complete problem, and that only probabilistic solutions are cost-effective.
Day 1 ended with dinner at a Yamato, my preferred Japanese restaurant in the city. Curitiba has a very large Japanese community, and lots of Japanese restaurants. Yamato, however, is the only one were you will stumble upon senior Japanese people, probably first or second generation immigrants, what I guess says something about its authenticity.
Right after breaking for lunch, but before actually going out, we made what so far is official group photo (I might try again as the shot was not a really good one).

On Monday Cédric told us that he and Sebastien had brought a bottle of French wine and some smelly French cheeses, and suggested that in the best Debian tradition we should have a Mini Cheese and Wine Party™. Sure thing! Luckily there is a farmer’s market 2 blocks from home on Tuesdays mornings, where I usually buy my fruits, vegetables, and cheese & friends, so the timing was perfect. I went shopping early in the morning, and bought a few things, and was back before it was the time to go to UTFPR. After the day-long hacking session we stopped by another store nearby to buy a few extra bottles of wine and other snacks.
At night, in my place, I ended up playing cheese master.
There was enough food that at the end we were all very full.
And with the spokesperson task of the day done, off to hacking I am!
