I talked in the Mozilla devroom at FOSDEM 2015. Here are the slides from it. It was recorded on video and I will post a suitable link to that once it becomes available. The talk was meant to be 20 minutes, I think I did it on 22 or something.
Sunday 13:00, embedded room (Lameere)
Embedded devices are very often network connected these days. Network connected embedded devices often need to transfer data to and from them as clients, using one or more of the popular internet protocols.
libcurl is the world’s most used and most popular internet transfer library, already used in every imaginable sort of embedded device out there. How did this happen and how do you use libcurl to transfer data to or from your device?
Note that this talk was originally scheduled to be at a different time!
Sunday, 09:00 Mozilla room (UD2.218A)
Title: HTTP/2 right now
HTTP/2 is the new version of the web’s most important and used protocol. Version 2 is due to be out very soon after FOSDEM and I want to inform the audience about what’s going on with the protocol, why it matters to most web developers and users and not the last what its status is at the time of FOSDEM.
I’m going there and I know several friends are going too, so this is just my way of pointing this out to the ones of you who still haven’t made up your mind! There’s still a lot of time left as this event is taking place late January next year.
I intend to try to get a talk to present this time and I would love to meet up with more curl contributors and fans.
I’m back home after FOSDEM 2014. A big THANK YOU from me to the organizers of this fine and totally free happening.
Europe’s (the World’s?) biggest open source conference felt even bigger and more crowded this year. There seemed to be more talks that got full, longer lines for food and a worse parking situation.
Nothing of that caused any major concern for me though. I had a great weekend and I met up with a whole busload of friends from all over. Many of them I only meet at FOSDEM. This year I had some additional bonuses by for example meeting up with long-term committers Steve and Dan from the curl project whom I had never met before IRL. Old buddies from Haxx and Rockbox are kind of default! :-)
Talk-wise this year was also extra good. I’ve always had a soft spot for the Embedded room but this year there was fierce competition for my attention so I spread my time among many rooms and got to see stuff about: clang the compiler, lots of really cool stuff on GDB, valgrind and helgrind, power efficient software, using the GPU to accelerate libreoffice, car automation and open source, how to run Android on low-memory devices, Firefox on Android and more.
I missed out the kdbus talks since it took place in one of them smaller devrooms even though it was “celebrity warning” all over it with Lennart Poettering. In general there’s sometimes this problem at FOSDEM that devrooms have very varying degrees of popularity on the different talks so the size of the room may be too large or too small depending on the separate topics and speakers. But yeah, I understand it is a very hard problem to improve for the organizers.
As a newbie Firefox developer at Mozilla I find it fun to first hear the Firefox on Android talk for an overview on how things run on that platform now and then I also got references to Firefox both in the helgrind talk and the low-memory Android talk. In both negative and positive senses.
As always on FOSDEM some talks are not super good and we get unprepared speakers who talk quietly, monotone and uninspired but then there’s the awesome people that in spite of accents and the problem of speaking in English as your non-native language, can deliver inspiring and enticing talks that make me just want to immediately run home and try out new things.
The picture on the right is a small tribute to the drinks we could consume to get our spirits up during a talk we perhaps didn’t find the most interesting…
This year I found the helgrind and the gdb-valgrind talks to be especially good together with Meeks’ talk on using the GPU for libreoffice. We generally found that the wifi setup was better than ever before and worked basically all the time.
Accordingly, there were 8333 unique MAC addresses used on the network through the two days, which we then can use to guesstimate the number of attendees. Quite possibly upwards 6000…
See you at FOSDEM 2015. I think I’ll set myself up to talk about something then. I didn’t do any this year.
Keeping up with our fine tradition, we will be present at that huge open source conference called FOSDEM in Brussels Belgium at the beginning of February 2013. It will then become our… 4th (?) visit there. I don’t have any talk planned yet, but possibly I’ll suggest something later.
Fosdem is several thousand open source geeks in a massive scale conference with something like twenty different parallel tracks, where each room basically is organized and planned independently. There’s no registration and no entrance fee. I usually enjoy network and security related rooms and of course the embedded room, which unfortunately seems to be stuck in a very large room of the campus with the worst sound system and audio conditions…
I look forward to meet friends there and have a great time with open source talks and good Belgian beers at night! If you’ll be there too, let us know and we can meet up.
The FOSDEM 2012 dates were recently revealed (4-5 February 2012).
I’d be happy to arrange a get-together for libcurl hackers at Fosdem this year. To me, Brussels, Belgium seems mid-europe enough to be able to attract a bunch of us:
- libcurl application users/authors
- libcurl binding hackers
- libcurl contributors
- … and everyone else who’s doing related activities or who just is interested
Potential subjects to discuss at such a meeting:
- what’s the most important stuff libcurl still lacks?
- what’s the least documented/understood parts of libcurl?
- are there shared problems several/many libcurl bindings have to solve?
- can we improve how we work/develop libcurl and bindings?
- what kind of beer is best at a curl meetup?
- [fill in your own curl related subject]
I would like at least 4-5 people voicing interest for this to be worthwhile for me to actually try to do anything. Please speak up on the libcurl mailing list, tweet me or mail me privately! The more people that are interested, the more planning and stuff we’ll do for it.
The thing is about 107MB big, 640×480 resolution and is roughly 26 minutes playing time. WebM format.
I did a talk today at Fosdem with this title. The room only had 48 seats and it was completely packed with people standing everywhere it was possible around the seated guys.
The English slides from my talk are below. It was also recorded on video so I hope I’ll be able to post once it becomes available online
We’re going to FOSDEM again. This year we’ll ship over the entire company (all three of us) and we’ll join up with a few fellow Rockbox hackers and spend a weekend in Brussels among thousands of fellow free software and open source hackers.
During this conference, 5-6 February, I’ve submitted a libcurl-related talk to the embedded-room that wasn’t accepted into the regular program, but I’ve agreed to still prepare it and I then might get a slot in case someone gets sick or something. A bit ungrateful as now I still have to prepare my slides for the talk but there’s a big risk that I’ve done it in vain! I’ve also submitted a suggestion for a second talk in the opensc/security room (also related to stuff in the curl project) but as of now (with but 16 days left) that schedule is yet to be announced so I don’t know if I’ll do a talk there or not.
So, I might do no talks. I might do two. I just don’t know. We’ll see.
If you’re a friend of mine and you’re going to FOSDEM this year, please let me know and we can meet and have a chat or whatever. I love getting faces to all the names, nicks and email addresses I otherwise only see of many people.
Update: My talk in the security room is titled “libcurl: Supporting seven SSL libraries and one SSH library” and will start at 14:15 on Saturday the 5th of February.
