20th anniversary

Just to let you know. We’ve been celebrating 20th anniversary also in Poland.
We spent 4 days near Polish sea. And we had great time.
Here goes pictures of cakes ;)
One is made by my girlfriend. Guess which one ;)

privacy settings for video materials from debconf

I’ve just tried to paste a link to video material from DebConf13 on my Facebook wall and I got this warning:
Could someone tell me what privacy settings are set on materials from DebConf?
Or maybe the more applicable question is what is the license of these materials?

looking for a specific FUSE based filesystem

Dear lazy web,

Friend of mine ask me for help to find out bottleneck of performance problems he’s dealing with.
Basically it looks like the most problematic are I/O operations and main reason for that are thousands of read/write operations on directory having about 150k files.

Solution is easy right? Spread those files among some hashed subdirectories and we’re fine.
But it is not so easy. There are about 200 bash/perl scripts operating on those files.
So it’s not so simple as `mv aaaaaaaaaaaaa.txt a/aa/aaaaaaaaaaaaaa.txt` and so on.
Those scripts were developed for the past 10 or more years… so yes… noone really knows how and why do they work.

So I’m thinking about another approach which should be much easier and cheaper than rewriting hundreds of scripts.

Something like proxy filesystem between those scripts and files.
So we could still move those files to hashed subdirectories but show them as they are in single directory for the scripts.

Anyone knows about such filesystem? Or is it something that has to be written?

And another question… is it worth to go this way? Is there a chance that some kind of FUSE proxy filesystem with really fast hashed subdirectories will be faster than filesystem with one directory with a lot of files?

Anyone tried such approach?

does Linux development include regression tests?

In October I announced that starting with 3.6 kernel it was eventually safe to unplug Zenbook.
Then in bugreport I was told that Sentelic touchpad driver was included in 3.8 kernel.
And guess what… I don’t have to patch kernel to have working touchpad using 3.8 kernels but I have to worry about unplugging laptop cause with 3.8.x kernel it’s quite common that it turns laptop off again.
So the question is… do we have any regression tests in kernel?
Should I test every kernel release between 3.8.5 and 3.6.0 to find the one that incorporated that bug again?

talk about packaging

Dear lazyweb.

I remember that not so long ago someone on shared info about he/she’s talk about packaging Debian with link to both video of the talk and sources of presentation. Since I would like to prepare similar talk for some local Polish OpenSource conference I’d be thankful if someone could remind me a link in comments.


Two full-time days to work on Debian

My current employer as a benefit offers two days of paid volunteer time every calendar year. In September I decided to devote this time for Debian project.

It wasn’t easy to convince HR and my manager (hi Gloria ;) ) that such activity can be considered as volunteering but I eventually did it!

So last Thursday and Friday were days I could spent working on my packages and other stuff related to Debian ;)

Let’s talk about effects. 5 packages updated, 16 bugs closed, more than 50 lintian warnings/errors solved.

Here goes changelogs from updated packages:

calcurse (3.1.2-1) unstable; urgency=low

* The Akamai Technologies paid volunteer days release.
* Package made from scratch (this was funny experience):

Despite this I did something else. I sent “end of the world” joke-mail to debian-mentors mailing list stating (ignore the fact that my own server marked me as spammer; fixed already ;P) that I’m going to review and try to upload every package that will be send to me during end-of-the-world day.
That action was quite successful although no package has been uploaded yet. I reviewed 4 of them and two more are yet to come.

So it looks that these two days sponsored by Akamai motivated me enough to spent few more days or even months and help other people to contribute to Debian.

Thank you Akamai!


It’s quite funny than the only service that is fully accessible (at least that’s my impression) through IPv6 is IRC which is usually considered as something deprecated/obsolete.

UPnP/DLNA player

I really tried to find solution myself but I failed.
Please tell me that we have some player that’s able to play videos through UPnP/DLNA *with* subtitles available in external file.
