More great bands

meta = {'category': misc, 'date': Tue 28 November 2006}

Thanks Wilmer for introducing me to a great Dutch space-rock band called 35007. Their sound is quite unique and reminds me of Porcupine Tree or even Mogwai. Unfortunately, like so many awesome bands it seems they’ve already split up so it’s unlikely I’ll ever be able to ever see them live.

Currently Playing: Riverside - Second Life Syndrome - Conceiving You

The more I listen to Riverside (the Polish progrockers, /not/ the Dutch cover band), the more I regret having missed their performance at Arrow Rock this year. The vocals match the instruments nicely and unlike a lot of other small progrock bands, you can hear they have a capable producer.

Muse in Den Bosch tomorrow ought to be good as well!

New blog title

meta = {'category': misc, 'date': Sat 14 October 2006}

I’ve decided to give this blog a more original title than “Jelmer’s blog”. From now on it will be named “Stationary Traveller”, after the song by Camel and because of my continuous presence on IRC, no matter where on the world I am..

Squashing Debian RC Bugs

meta = {'category': debian, 'date': Mon 02 October 2006}

I spent most of my weekend at a-eskwadraat, for the Debian Bugsquashing Party and the UKP (qualifying round for the national championships), right after I got back from New York. Unfortunately my jetlag caught up with me on the sunday, so I overslept and woke up around four. :-(

My contribution to the BSP was small; I didn’t fix any release-critical bugs though I did work on getting the next CtrlProxy out, which should fix at least one RC bug.

Currently playing: The Black Crowes - Struttin’ Blues

Update(15 October): Oops, looks like I still had this entry marked as “Draft” instead of “Publish”

More use of IDL

meta = {'category': samba, 'date': Mon 25 September 2006}

The IDL (r)evolution is really taking place now. We’re slowly getting rid of the Samba3 DCE/RPC parsers that we were previously using and are moving towards new code generated from the IDL by pidl.

An increasing amount of dissectors of wireshark is now also generated from IDL, thanks to the work of Ronnie Sahlberg. There’s a list at their wiki.

New job

meta = {'category': samba, 'date': Sat 02 September 2006}

Google’s Summer of Code was again a pleasure to participate in! I’m quite pleased with the overall results and have enjoyed working on the CUPS tree. Mike, main author of CUPS, has merged my Kerberos branch into trunk a couple of days ago. It should be part of the upcoming 1.3 series. My aim is to stick around and maybe work on SPNEGO/NTLMSSP support.

As of recently I have started working part-time for SerNet. I’ll be working on random Samba bits for them, all free software. The first thing I’m working on is backporting the excellent libndr (one of the core parts of DCE/RPC) subsystem from Samba 4 to Samba 3.

The university year has also started, so my activity in free software will probably decrease a bit in a few days.

Summer of Code

meta = {'category': misc, 'date': Fri 25 August 2006}

I’ve finished the last few bits of my Summer of Code project. Client and server side authentication to CUPS using Kerberos work now, and that includes both the administration tools and IPP.

It’s been fun working on CUPS and now that I’m a bit more familiar with the code, I’d like to have a stab at implementing SPNEGO and NTLMSSP support as well. This should be much easier now, as I have already done the required work to support WWW-Authenticate: Negotiate, one of the prerequisites for both Kerberos and SPNEGO.

Rolf Kvinge also seems to have been successful, Mono now has a self-hosting Visual Basic.NET compiler. I’m looking forward to trying it out, once I can get my hands on a binary to compile it with…

Using bzr-svn in production

meta = {'category': bazaar, 'date': Wed 19 July 2006}

At last, I’ve started to use bzr-svn in production. I’m now working on Samba in bzr, pulling from and pushing to Subversion branches as if they were native Bazaar branches.

It seems to work quite well. Bazaar can be slow dealing with large history, but that appears to be a temporary issue rather than a design flaw.

I’ve also published conversions of the two main Samba branches on the web at http://people.samba.org/bzr/jelmer/samba/.

Now, time to get the Subversion Python fixes into all the distro packages.

Pushing Mercurial branches into Subversion using Bazaar

Next items for bzrsvn

meta = {'category': bazaar, 'date': Thu 29 June 2006}

Now that commits, merges, renames and working trees work in bzrsvn, I’m looking at the next items on the list:

• push into Svn repositories
• creating working copies from Bazaar
• performance improvements

For the plugin, I’ve had to make quite a few changes to the Python bindings to Subversion. I recently became partial committer to Subversion. My patches are listed by the contribulyzer and commits in the archives. It’s been fun working with the Subversion developers.

Ethereal renamed

meta = {'category': misc, 'date': Mon 12 June 2006}

It looks like Ethereal has been renamed to Wireshark. The reason specified on the website is the fact that Gerald (Ethereal’s founder) has switched jobs and apparently his old employer owned the trademark.

Bazaar Sprint

meta = {'category': bazaar, 'date': Sat 10 June 2006}

It’s been a fun week. I visited the Bazaar sprint in London with LarstIQ and had a great time meeting the core developers. Especially the pair-programming and test driven development was very interesting; the number of lines of code I wrote was smaller than usual, but I have never spent so little time debugging. Among the things I worked on were Commit Builder with Robert and some more work on bzr-svn.

The Arrow Rock festival yesterday was great. I was a little skeptical about Porcupine Tree’s live performance, but I was very pleasantly surprised. Roger Waters’ show was shorter than announced (3 hours) but very good nonetheless. Queensryche was the only disappointment - they played only a few old songs and their sound was pretty bad (at least from where I was standing).

SoC Deadline

It’s almost 2 AM here, in other words, 17:00 PM in California - just a few more minutes before the list of SoC applicants will apparently be published. Hopefully one of my applications will be accepted; the quality of applications appears to be better overall than last year, so it’ll be tough…
