Present Perfect

Weekend

Spent most of my weekend struggling with RefDB, a database to manage bibliographical references. My dad's doctorate thesis is due Friday, and he didn't use the program I installed 20 months ago. Now, in his final days, I get to put the pieces back together.

But I never really thought xml/docbook was an intuitive toolchain to get running, and RefDB doesn't help much either because it's so completely untransparant. Tools fail silently on bad input, or fail generically without saying where something was wrong, so I spent most of my time trying to figure out what exactly it was not parsing.

In the end it turned out that the RIS file my dad gave me contained garbage control characters, and it also looked like RefDB didn't really like names with accents in (like, all the Irish guys and some Dutch guys). I also started my use of RefDB with a simple FILE* non-cleanup patch. I'm not entirely sure though I want to go through the pain of sending all stuff I find upstream for a package I myself have no use for.

Then I started thinking, man, this is probably exactly how some people feel about GStreamer. Some stuff I consider natural is completely nonintuitive to them, and things break in mysterious ways when they are run slightly differently from our local setups. I mean, I'm pretty sure the RefDB author has everything running very smoothly on his home machines...

Anyway, after 30 hours of fighting with docbook, xml, RIS files, unreadable C code, mysterious options, and unforgiving configuration files, I sort of cooked up a RefDB-based xml file containing my dad's bibliography. I hope he gets back to me soon on whether or not it's ok - you can just know he's going to want to have everything fixed on Thursday when I don't have any time for it...

Inbetween, we watched Grosse Point Blank and Antitrust. I recognized Miguel right off the bat in that very short flash. The movie wasn't too bad, it just made my toes curl a little at points. Let's just say it wasn't very believable. Grosse Point Blank was very good on the other hand.

GStreamer

Picked apart the Fedora 2 test rpms to check for patches. I just don't get why people don't submit their packaging patches upstream. The spec looks really ugly without it having to be. It also has the docs disabled, while they build fine here in a clean root. Why aren't we getting bug reports for this ?

Anyways, I guess I just have to mail and prod and make people aware that we care.

The build bot setup is starting to look nice now. We added the powerpc machine on my desk in two minutes. I'm sure the other GStreamer developers are starting to get irritated at all the random commits we're doing.

I'm sure Ronald is going to kick my ass some time soon too, but it just had to be done.

libuecp

I got a mail from someone asking about it, so I went back to check and noticed I had some stuff to change in my savannah checkout. After resubmitting keys and changing config files, I could check out my project again. It still works, I guess that's not a bad start. I have no way to develop on it anymore however as I don't have any RDS encoders lying around :)

Update

Man, our company logo is so unbelievably sexy as a favicon... I just keep staring at the tasklist at the bottom and the cute little cartwheel.

Short recap

Too much has happened, so let's make it short.

Fluendo exists now. wtay paid us a visit. Spent long days and nights at too many restaurants, too many bars, and too little time in bad. Had productive discussion with Wim. He's just amazingly good at designing. When we got sidetracked he showed me a beautiful sound server design he had prototyped, but he stopped working on it after seeing that his test code worked. Sigh, I hate that guy :) Maybe an idea to pick up later ?

Norwegians complain a lot then buy presents to make up for it :)

Discussed clocking with him too - not sure what was wrong in 0.6 with it, it seems like it was just some stuff left to implement. Will need to pick that up really soon and decide what to do.

Johan set up buildbot. Output looks nice, will be useful ! Hope we can fix the last issues with it.

Sister dropped by too. Nice to see her again, I don't really have time to miss people, they drop by anyway :) Next time have to get her over in the weekend, not much time during the week.

Spent a whole day listening to Jeff Buckley, then the cocktail bar at night was playing Grace. Nice. Sad.

Pushed out releases of nautilus-media for GNOME 2.4 (0.3.4) and GNOME 2.5 (0.5.3) Next week Johan and I will be working on fixing all bugs that are in it, but jdub needs a release now.

This week I fixed around 12 open bugs in GStreamer. Still too much in maintainer mode, fixing dist issues, breaking up modules, and so on. Did manage to finally write the unversioned frontend binaries for the tools, was happy about that. Simple idea, simple design, works as expected.

Did a release of 0.7.4 for GStreamer and GStreamer Plugins. Then did a release of 0.6.5 for GStreamer so they both use the same frontends. Tested theory of parallel installability by making packages and discussing with Matthias. Seems to work out fine. Now I need to figure out how to handle the GConf schemas. I guess I should make them versioned too. Sigh :)

Got my wallet lost or stolen. Suckage. I paid for one of the dinners with my bank card and got the money from the others, so I lost 150 euro. Should have treated them, wouldn't have cost me anything afterwards :) Will be painful to get cards and papers back.

Mailed booqbags to ask where the hell my bag is. They're sending it again. I hope this time arrives.

After two years, the quest is finally over. Three Ruperts made their way to Barcelona ! One is sitting on the Powerpc at work, one on the stack of DVD's containing three complete series of Family Guy (that sadly don't play on my PS2, so need to finish getting DirectFB output on Dave/Dina so I can watch them), and the third is keeping Kristien safe in the bedroom. I owe someone a bunch of thanks !

Got Soulcalibur 2 from Wim and Christian because they complained I didn't have any real games (Not sure how they missed great stuff like Britney's Dance Moves and Buffy The Vampire Slayer though). It's sucking up all my time, I'm going to stop hacking on GStreamer I think so I can become an expert at Soulcalibur 2.

So, so far for the short update. I'll go back to trying to be more regular now.

GStreamer

Getting ready to do a release. Did a prerelease yesterday, got a little bit of feedback on it. Some last minute memleaks got fixed but they introduced crashers in some plugins so I reverted them for now. We can fix them properly after the release.

I'm hoping to get into a more regular release cycle from now on.

Meanwhile jdahlin is making progress on the media test suite, it's starting to look really nice. I hope he likes his new job so we can keep him around.

Yesterday was great. I reserved the day for doing only code. I wrote a C frontend to our versioned tools so that they would be able to call the versioned binaries. This was a requisite I had for doing decent packages that were parallel-installable. It was so nice to just program one thing well with a clear set of requirements and a clear end goal. I had started feeling like I didn't know how to program decently any more, but it turned out it was quite alright.

Work

There was an idle PowerPC sitting in the design department. It's now sitting on my desk. Yellow Dog 3.0 looks really nice. I remember trying 2.x on my old powerbook, but that still had that ugly-as-hell fluxbox installer and it didn't get my keyboard right.

With 3.0 I feel right at home. I moved over some of my desktop settings, started setting up gstreamer from CVS, and installed mach to build some packages I needed to get the CVS build to work. It's nice when you can just install a tool you've written on a platform that you never tried and have it Just Work.

The machine is dog-slow at compiling though, but it'll be good for test builds and test runs.

fedora.us

Still not sure what to do there. I've reworked the GStreamer website and one of the last things on the TODO list is to rebuild the Red Hat/Fedora package area.

I have always wanted this to be completely compatible with fedora.us repositories, for the sole reason that I prefer to work with a community effort project so fedora.us's goals are more aligned with that than freshrpms.

But, I think I've been with fedora.us for more than a year now, and some fundamental problems just aren't getting solved. I agree with most of the guidelines, and have made my peace with those I don't agree with, but the sad fact of the matter is that it's just not working. The QAPriority Queue (what an ironic name) contains over a hundred packages.

Yes, they have to be reviewed properly. Yes, we don't want crap. But some of those packages have been stuck there for over half a year.

By contrast, I just asked Matthias if he could put together a gtk-doc package of 1.1 for the YDL 3.0 machine I installed today, and it's no problem at all.

So, even though fedora.us wants to be a community effort and Matthias likes to go at it alone, I have to admit that at the end of the day, as a packager of GStreamer wanting to get GStreamer packages out there, fedora.us is not working as a solution to that problem.

I've been procrastinating updating packages because I don't like working towards a solution that I don't know yet. So today I make the decision to change the solution. The solution will be to promote both fedora.us and freshrpms as viable packaging solutions for GStreamer, and let the users decide.

With that settled, I can stop procrastinating on getting packages built, and get on with it.

About time too, since I'm doing a release today...

Rhythmbox

I am pretty sure it doesn't like me. Tool's Aenima album is filled with amazing tracks. There's one stinker on it, "Die Eier von Satan", which is some German guy rattling off the recipe for satan's eggs, and there's some filler on it in the form of a wheel organ ditty.

What does Rhythmbox give me on the way to work ? Two times the ditty and three times the stinky song. My day is screwed before it has even begun.

I'm pretty sure there's a lot wrong with both randomize functions, and pseudo-random playlist generators in general. I've noticed the same problem in Dave/Dina when trying to select random playlists based on parameters. I have some ideas on why that is but I'll need to investigate and code to test the ideas.

Matrix

Went to see the final chapter. When it was not overly hollow it was too emotional. All in all, that's two hours of my life I'm not getting back. But I owed it to myself to see it.

Still haven't seen ANY of the LOTR movies, woo !

Home Improvement

Time for some chores around the house. Of course, nerd chores. First task at hand was to have an automatic updater for my dyndns account set up.

Felt like an old-school hacker when I cooked up an expect script to retrieve the assigned IP address from my NAT Nokia router through telnet; five minutes of work after understanding enough of expect to see what I want.

Then tried this with ez-ipupdate, but that only allowed me to set the address on the command line, which when run as a daemon from init is no good of course. Started putting in an address-command argument to ez-ipupdate, but after going through the source a bit which was full of static vars and irc-daemon-like maze code, and also after seeing that the included debian patch in the .src.rpm was so huge that the original was even more messy than I thought, I gave up.

ddclient seemed to have an option for running an external command to get the ip though, so that worked out fine as an alternative.

So, that was two hours wasted.

Second task was making sure the bits from fedora.us and rpm.livna.org get mirrored. I would love for someone to write a very simple program that sets up mirroring scripts for you based on collections of files you want. I don't want the whole fedora.us mirror, just stuff for RH9 and F1, and only stable, testing and unstable.

Having to write these scripts manually all the time (in this case, with lftp) is a pain.

Another hour and a half wasted.

Dave/Dina

Finally started doing some work again, prompted by another user trying it out and poking at bugs. Started with figuring out a better layout for the package tree, making sure the online and local one are in sync, and starting to fix bugs by rebuilding packages. Will take me some more time this week

Weekend

jdahlin dropped by last night. We were wondering how it was going with him. He stayed for dinner and a movie, "Love and Sex". Quite alright, and Famke Janssen is never bad to look at.

To rent movies I needed a copy of my appartment rental contract and my NIE papers. The video store also had a Lego Mindstorms set for sale, which prompted a discussion between Johan and me. I have an expensive Mindstorms set lying around doing nothing. So Johan suggested I do something really useful with it, like, pushing the eject button on a floppy drive.

But then it hit me - I have a very simple Mindstorms project that could benefit Dave/Dina.

See, I have this one remote that, by typing in some codes, can emulate any of 200 remotes. Yesterday I was thinking that it would be nice to have all these config files out of the box to choose from, but it would be very painful to push all those buttons.

But, if I made a lego machine to push the buttons, and a LegOS app to control it, and have it communicate directly with lirc so it can ask for another keypress when it didn't work well, I could easily let the thing run for a day to make it learn all the codes !

Hm, that really makes me want to try LegOS and see if this is possible, I need to poke some friend who knows about LegOS to check :)

GStreamer

Still spent more time fixing up docs, adding API to the doc build, still busy with the website, still busy with cleaning up some of the error stuff. I fixed up the player library and the player to actually display these error messages.

So, when an error comes up, you get this dialog. And when you click on Information (which really should be a "Debug Information" button), it gets replaced with this dialog.

I like it, because if users send us the debug information we can check where the error is coming from.

Still, UI wise I would prefer the original dialog would expand to show the debug info on clicking Information...

Tomorrow is Johan's first day at work. Wish him luck, he'll need it...
