How old your $HOME is?

Today I got hit by some bug in Ubuntu. I checked what is going on and reported to bug tracker. But what is found out during checks?

Files from 2001 year. Yes, my “~/.bash_logout” is over 9 years old now. It only runs “clear” on text consoles but it is oldest not changed configuration file in my system. Created under Debian ‘potato’, survived upgrade to ‘woody’ and then to ‘sid’ which I use since it was created. During that time I had one system re-installation — when switched to x86-64 architecture.

According to results of “find” command older are only files from my master thesis which I wrote in 2000/2001. How old your $HOME is?

UDS-M continues

Today is a last day of Ubuntu Developers Summit. I plan to attend few sessions, on evening maybe go to Brussels for some shopping (UDS is in a middle of nowhere) and tomorrow I hope to fly home.

So far I attended several sessions, some were too Ubuntu specific for me to get idea what it is about (PPA or other Launchpad related services for example) but in general time is not wasted.

Monday

Missed keynote ;( I blame Belgium train company for it. But I fetched it from YouTube so will watch it during return travel. Then Ubuntu on ARM project had private meeting where we had a chance to connect faces to names and got some short introduction. That was all for me — after lunch^Wbreakfast I got to sleep. During dinner time I met some fellows from old time: Rob Taylor, Neil Patel, Peter Goodall and spoke with several other guys.

Tuesday

ARM talk about toolchain was great. GCC 4.5 is what we want for our project I think. There was also warning that switching to 4.6 version will probably require transition process. Then I was on AEL/ALIP talk — should attend SoC:Dove talk instead. Session about building root filesystem images was started by me and then lead by Luïc. There was some good ideas told, many tools were mentioned so I will have something to do in near time. Another talk about toolchain and then Device Tree overview — what it is and why we want it.

Wednesday

Another sessions related to development tools for attending, one about U-Boot features and performance and three about building ARM archives. Kiko’s introduction to ARM was interesting presentation.

Day finished in Waterloo where we had a dinner with ARM Ltd. people. Nice chats with good food and wine.

Thursday

Attended memory footprint talk, next was kernel version alignment where people from ARM vendors gave us informations about their work on getting support for products in mainline kernel. Looks like 2.6.35 will be used in Maverick release.

Later was marketing talk about Freescale i.mx51/53/508 cpu family plus mentioning of Cortex-A9 based i.mx61/63 chips which will be released next year. Rob Herring mentioned that there may be BeagleBoard like device with i.mx53 processor available.

Zack from Debian told about cooperation between Debian and Ubuntu developers from Debian perspective. It was nice talk. Next was about plumbering and explained how HAL got removed, how other components changed in base of base system. Looks like upstart developers know what they do and where they are going.

As a way to get something different I went to QA session about tracking performance on different architectures. Mostly it was about Phoronix test suite and how it can be adapted for ARM. Then went to cross compiler packages which was nice session.

Last session was SoC: OMAP3/4 talk made by Texas Instruments people. They had Blaze with them, shown Ubuntu Lucid on it and then booted to Poky Linux to show OpenGL/ES and video decoding capabilities. Playing 6 video streams on rotating cube was nice. Playing 1080p videos without any visible frame drops was another nice stuff. And there will be OMAP4 based PandaBoard developer board similar to BeagleBoard line. When it arrive was not announced.

After that I went to Brussels with TI people for some food and beer. Discussed on many things, I shared my suggestion on how to make PandaBoard really nice, we did few beers. It was good spent time.

Friday

First got to rootless building of root filesystem images, then was ‘mukluk’ soft bootloader which is yet-another-kexec-based-bootloader. A bit of NIH syndrome but can grow into something interesting and kexecboot got mentioned few times.

UDS-M day 0

Tired, tired, tired. That’s how I feel now. And all by one trip which had to end over 12 hours ago…

I left home after 13:30 and took taxi for bus station. Then bus to Berlin Schonefeld airport — arrived before 17:00, passed security check and found good place to wait for depart. Some flights were cancelled, some were late but my to Brussels was still listed as operating one. Forty five minutes before depart it got cancelled 🙁

So let’s check options… Other flight maybe? Frankurt and Köln were listed still but who knows will they fly… So I decided for train. Launched browser, accepted data roaming warning and started checking. One hour later, at Südkreiz, I had a set of tickets in a pocket. Paid 160€ for it — more then my flight tickets in both directions…

My cellphone got discharged at that moment, so I took laptop from the bag and connected both devices to get some power for phone. Worked good.

Went to Berlin Hbf station, got some food and beer and half past midnight took first trip: to Köln. I discovered where power sockets are but it was a bit too late to take such seat 🙁 But I managed to get about 3 hours of sleep.

Köln station had free wifi at Starbucks (btopenzone network) so Twitter, emails and checked some UDS travel part. Then TGV to Brussels. This time power sockets were easy reachable so laptop got charged a bit and phone to the maximum. Watched a movie, checked some code.

Brussels station was disaster. Ticket machine did not accepted any of my cards so I got into queue so first train got missed. Second one got cancelled… One extra hour on that crappy place where there is no such thing as information in English…

Now I am somewhere between Brussels and La Hulpe and hope that will not miss station. Then finding hotel, register and trying to find coworkers which I never met.

And just because one vulcano did what it did I had to spend extra thirteen hours for a trip 🙁
