Fosdem 6-7 Feb in Brussels Belgium: I’m going and I’m doing a Rockbox talk.

foss-sthlm 24 Feb in Stockholm Sweden: I’m arranging and I’m doing a curl talk. This isn’t really a “conference” but I wanted to mention it anyway!

IETF 77 in Anaheim USA, March 21-26: While it would’ve been a blast to go there, it really doesn’t sync very well with my work schedule and other lifely matters so I’ll pass this one! Sorry all friends whom I otherwise would’ve met there!

OWASP AppSec Research in Stockholm Sweden, June 21-24: since it is in Stockholm and these guys tend to have interesting stuff I just may go. It depends a little on how the program will end up and if I manage to cough up a talk for it.

IETF 78 in Maastricht Netherlands July 25-30: I want to go there and I think the timing is much better for this IETF meeting than the previous few ones. With a little luck we’ll get both the HTTPBIS and the HTTPSTATE groups to have meetings here, and who knows what other fun there will be?!

Slackathon 2010 in August in Stockholm Sweden? It’s not decided yet but I hope they will go for it and I will try to attend. Slackathon reminders.

FSCONS in Gothenburg Sweden Oct/Nov: Since this is our current major open source conference in Sweden I really want to go and I hope to be able to do a talk too. I don’t think the date is set yet, which is a bit unfortunate since November this year is a bit special to me so there will be some other events going on at that time that risk conflicting with FSCONS.

This year, the event was scheduled to take place immediately after a bunch of core OpenBSD developers had had their “hackathon f2k9″ in Stockholm, so they could now boast with a series of very well known and very knowledgeable OpenBSD kernel hackers. As I am really not more than a distant observer of the OpenBSD project this of course put the lights on a lot of dusty corners I had no previous idea about. I’m not really a stranger to kernels and kernel hacking in general, and I must confess I had a great time and the team who spoke of various very detailed kernel topics are charismatic and put on a great show.

So I learned about the terrors of the VFS layer and hacking it (and how they’re working on making all the involved caches dynamically sized). I learned how to do active-active syncing  of pf-based firewalls (basically using two independent firewalls in front of something), or at least how the guys made it work fairly well. Or how the pf firewall was optimized to double its forwarding performance. And I got to hear a few wise words from Theo de Raadt and learn not only about their 6 month release schedules but also their plans and ideas around solving problems with livelocking and more. Not to mention the talk about managing physical memory, or the work to get OpenBSD ported to sparc64s with hardware-based virtualization support.

Taken all the hardcore kernel talks into account, I think my own talk on libssh2 (just before dinner) felt like a very light snack to chew and possibly a tiny bit out of the general topic… Anyway, I gave a quick overview of the project, how it started, why it was started, what it is and a bit how it works etc.

The slides from my slackathon talk. I expect to re-use a fair bunch of that, with some improvements and additions, in my libssh2 talk at FSCONS later this year.

Looking forward to Slackathon 2010!
