DebConf7 finished today. This was my first DebConf, and probably not my last one :-) I had a really interesting time in Edinburgh, despite the weather (but at least we are prepared for DebConf8 now!). The organization team really did a fantastic work, the venue was gorgeous, etc, etc, etc.

Again, I was positively surprised by how nice everybody was at DebConf. It’s weird to think that the same people are part of the regular flames on the mailing lists. Which proves that most flames are just caused by people being passionate about Debian, and looking for the best for the project, and not by people trying to be annoying, like one could think :)

I gave a talk about the usual QA stuff I’m doing: archive-wide rebuilds, piuparts runs, and how to make all this more efficient by working inside the collab-qa project. So far, it’s not like a lot of people have been joining the project, which is kind of a failure. But at least everybody seem to think that the idea is good.

I also gave a lightning talk about Debian Package of the Day, which I didn’t plan to give originally (I think I never prepared slides in such a short time). I think it was well received, and we even got a new submission half an hour after the talk.

I even managed to clear some tasks on my TODO list during Debconf, the most visible one being the “automated monthly mails to maintainers of packages with serious problems”. I was quite afraid of being flamed, but I sent 250 mails, and only one person replied aggressively. I also got a lot of positive feedback, so the next batch will probably use slightly less strict criterias.

And of course, the most important result of debconf was the numerous discussions, that resulted in a lot of good and interesting ideas.

You probably all know tetrinet – if you don’t, you should really try that game. There are several servers for that game out there, and one of them is tetrinetx. It is packaged in Debian, but it has several problems:

• It doesn’t support tetrifast mode. So you have to deal with that stupid 1-second delay before the next block appears.
• The code is truly horrible. From main.c:

  #include "dns.c"
  #include "utils.c"
  #include "net.c"
  #include "crack.c"
  #include "game.c"

  That gives you an idea, right ?

A few years ago, I worked with a few friends on improving tetrinetx. This resulted in:

• Massive code cleanup
• Tetrifast support
• Stats stored in an MySQL DB, so you can compute nice stuff (time wasted per day, etc)
• More stats: blocks drop rate, etc.

This is hosted on sourceforge under the name tetrinetx-ng, but it hasn’t seen any activity for the last two years.

It would really be great if a tetrinet fan could take over the project and start making it alive again. Then tetrinet.debian.net could support tetrifast ;)

Also, I could try to setup a server with tetrinetx-ng. Someone wants to host tetrifast.debian.net for me ? Needed: MySQL DB + Apache (for the stats), + not being afraid of insecure code (doesn’t need to run as root)

I am considering switching from SVN to a distributed SCM for my personal stuff. I had a look at git and mercurial, but neither really support branching a sub-directory:

Often, I am working on a big private project, and, while working on a sub-project (stored inside the project’s repository), I’d like to share that sub-project with others. So there are actually two problems:

• being able to checkout/branch/clone a sub-directory
• possibility to control access on a per-directory basis

SVN only partially meets my needs with that (it’s possible to checkout a sub-directory directly, for example with svn co svn://svn.debian.org/svn/pkg-ruby-extras/tools/ruby-pkg-tools). I think that it’s possible to do fine-grained access control
using libapache2-svn, but I haven’t tried yet.

It seems that mercurial can do that, using the forest extension. But you have to convert the specific directory into a repository, with a complex step to keep the history.

Amongst the distributed SCM, is there one that supports that ? (at least the sub-directory branching part)

Consider the following command:
echo <(cat /etc/{motd,passwd})

(you can replace "echo" with any command that takes one file as argument and cannot take it as stdin)

It's obvious that the goal is to expand this to:
echo <(cat /etc/motd /etc/passwd)

Then to:
echo /dev/fd/63

However, it doesn't work like this:
$ echo <(cat /etc/{motd,passwd}) ++ cat /etc/motd ++ cat /etc/passwd + echo /dev/fd/63 /dev/fd/62 /dev/fd/63 /dev/fd/62

But bash doesn't work like this. Brace expansion is done first, but inside parameters of the command (that is, <(cat /etc/{motd,passwd})) not words. So when <(cat /etc/{motd,passwd}) is expanded, the prefix is <(cat /etc/, the suffix is ")", so it's expanded to <(cat /etc/motd) <(cat /etc/passwd).

After reporting a bug about that, Chet Ramey gave me the correct way to reach the initial goal:
cat <(eval cat /etc/\{passwd,motd})

Just received that, in reply to a mail I sent:

MailInBlack seems to be a french company. No wonder why they guarantee that 100% of spams are stopped. (To be fair, I am not sure yet of who fucked up, it might be the admin)
