Mini report and pictures from FOSDEM 2010

Just came back from FOSDEM 2010, i don't have much to say, since it was quite a flash journey for me, i left home Sunday at 7:30AM and got back at 7:30PM. I originally planned to go on both days but this year Haiku didn't have its own stand, instead Haiku was present Sunday in the Alt-OS (ie: not Linux nor BSD) DevRoom in the form of several talks by François Revol, Olivier Coursière and Niels Reedijk. The Alt-OS DevRoom was a (~50 people capacity) class room, that François entirely managed and organized, he invited other projects to give talks and scheduled the talks.

Unfortunately, i arrived a few minutes after Olivier started his "Introducing Haiku" talk, and the room was so packed that i couldn't even get in the room (for safety reasons). This is what i was welcomed with" :)
When i managed to enter, for the next talk, there were still no seats available and stood up like ~30 other people. I eventually managed to seat next to the Haiku guys (Jerôme Duval joined us in the afternoon).

Most of the talks were quite low level for me, but very interesting nonetheless. The room was full most of the time but not as packed (with people standing up) as in the morning. Olivier and i had our laptops on our tables with Haiku running, and when possible, between talks, we had a few quick chats with interested people. I had to leave very quickly right after Niels talk which i'd like to note, was a very original and inspiring talk about project goals, the notion of "future" and how it relates to Haiku (i hope i got it right Niels :) what about publishing a text version?).

Sorry for such a brief report, i mostly wanted to publish some pictures as i often regret not doing so, i'm sure François, Niels and Olivier will have more to say :)
Thanks for reading, and lets all thank François for organizing Haiku's presence again this year.

Here are the pictures, i'm sorry i didn't catch everyone (some pictures were too blurry to publish), will do better next time.
(BTW i'm not sure what is the proper way to attach images in blog posts)

Using malloc_debug to Find Memory Related Bugs

There's plenty of ways to introduce subtle bugs into your code that give you a hard time finding and fixing. In this post I'd like to introduce you to malloc_debug, a heap implementation with added debug helpers, and outline how it can be used to find some of these problems.

Hey, that rhymes even! :P Lesson 4 is now out. Decision-making and repeating instructions are on the agenda for this one, expanding the repetoire of basic skills for writing code. Learning to Program With Haiku, Lesson 4.

Continued (mis)adventures in programming for all of the curious into the insights of being a codemonkey. In this lesson, we examine the different types of data we can use, a more in-depth look at how to print to the screen, and more! Learning to Program With Haiku, Lesson 3.pdf All previous lessons have received some minor revisions and code is now colored for better readability.

A week or so later, there is another lesson for download. These are meant to go at a reasonable pace to ensure that the concepts presented are learned well. Enjoy! Learning to Program with Haiku, Lesson 2

Calling All Haiku Developer Wannabes

Have you ever wanted to learn to program for Haiku (or something else) but never had the money or the chance? Has something else gotten in the way? Even though I still don't have any real motivation to write code, right now I have plenty of motivation for writing about code.

I'm going to be publishing online programming lessons whenever I have some time. Usually this will be about one per week, but may happen more or less often on occasion, depending on how my spare time runs. These lessons will be available in PDF form under a Creative Commons license that will give me some options should I ever want to publish them in dead tree format.

Considering that I write fairly well and I've been teaching for more than 10 years now, this is quite an opportunity for someone who wants to learn to code. To kick things off, here's the first one. Learning to Program With Haiku, Lesson 1.

Everyone loves benchmarks

In these exciting times, during which Ingo Weinhold is making great progress with some performance optimizations in the Haiku kernel, I felt this strong urge to conduct some benchmark results, even if that caused me great deal of pain in setting up all the test platforms! The results are quite interesting, even though I didn't manage to test all possible combinations of host platforms and file systems.
