curl talk at foss-sthlm

I’m now scheduled to do a short talk on curl and the project on the foss-sthlm meeting in Stockholm on February 24th! As you can see on the site, there’s also a set of other fun subjects around Free and Open Source Software.

The material on the site is all in Swedish and all talks are expected to be mostly in Swedish.

Our merry foss-sthlm effort has really taken off in a great way and more than 50 persons have already signed up to show up at the meeting and we have 5 other speakers apart from myself lined up. The program isn’t really fixed yet, but it certainly looks like it’ll end up at least mostly the way it currently looks.

If you are in the area and have an interest in FOSS, consider showing up!

Oh, and my brother Björn is scheduled to talk about Rockbox at the same event.

Going Fosdem 2010

Oh what the heck, we plan to bring every single employee of Haxx over to Fosdem 2010. Yes, that means all two of us!

I hope we’ll manage to join up with fellow Rockbox hackers then and it would be great fun to meet other friends from other projects and open source activities too.

I’ve not been to Fosdem before, and I’ve offered to do a talk there but so far I’ve not gotten a response from the responsible guy in the “embedded dev room”. We’ll see how that ends.

Rockbox on iPod Nano 4th gen

Michael “TheSeven” Sparmann is one of the primary magicians behind the recent linux4nano efforts and he has done a lot of the Rockbox port for the iPod Nano 2nd generation.

Some 10 hours or so he posted this neat picture:

Ipod Nano 4th generation

… showing off custom code running on an iPod Nano 4th generation. If you want to keep track of his/their work on recent iPods, follow @linux4nano on twitter. I do!

While this is not yet Rockbox on the device, this is a least proof it can be done and this could indeed be seen as the first tiny steps towards a full port! Good job Michael!

Mini 2440 Lyre

On ebay there’s a fancy S3C244-based board named mini 2440 with a 3.5″ touch LCD attached on sale for 85 USD. 64MB ram, 400MHz CPU, a nand flash and more. Lots of stuff for the money.

mini2440

The guys in the lyre project seem to have adopted this as yet another hardware platform to attempt to run Rockbox on. After their Atmel AT91SAM target was ditched, they went the ARMopendous route and now this seems to have entered. This third hardware platform is called the Lyre prototype 2

You should note that this Mini 2440 board has no batteries or anything and thus is not really meant to be a portable device in this shape.

“Bob” seems to have initial Rockbox code running on this device, and well-established Rockbox hackers JdGordon and domonoky have both ordered their own kits so the future looks bright.

My Nordic Free Software Awards 2009 nominees

Hey, it’s really about time to nominate your favourite Free Software persons and projects from the nordic region for the 2009 awards before the time runs out.

This year, I decided to nominate the following “nordic” heroes:

Simon Josefsson

For his excellent work in GnuTLS, libssh2 and a bunch of other projects.

Henrik Nordström

For his work in the Squid project, and his efforts within IETF and its HTTP related struggles and more.

Björn Stenberg

As the primary founder of the Rockbox project. He started somehting special back in 2001 that now is a huge, thriving and succesful Free Software project.

As you might spot, I favor “doers”. I don’t believe in the concept of “nordic projects” when it comes to free or open software – the entire concept of open and free should mean that projects cross borders and regions.

In fact, it feels so out of the ordinary to think about open source people in a geographical context I find it hard to come up with a lot of names. It would be cool if ohloh had some ways to list people and projects based on where people live.

Then again, if a person from a nordic country moves somewhere else, is he or she still a nordic person? Does it depend on where the person lived during the actual act? Is Linus Torvalds a nordic person since he was born, lived many years and started his big project in Finland?

(yeah I already blogged about this subject but hey, it can’t hurt can it?)

Rockbox presentation video

Robert Menes held a talk at the NYLUG a while ago about the Rockbox project:

I started out the talk by giving a little background on Rockbox; basically how it started, how it was ported around to new targets, and how the community grew as interest peaked. I showed off features of Rockbox, as well as supported targets, nearly supported targets, and even in-progress targets. I then went into describing Rockbox’s features in greater detail, and then a run-down of the development process, as well as how to compile your own builds. Many people asked questions along the way, so I answered them as they were asked. I also think that people were probably shocked at the sheer amount of targets that were shown off (nearly 40 DAPs were there!)

The 76 minute (1.6 GB) video from that event is available from the download.rockbox.org mirrors. Set your video player to stream from there unless you really want to download that entire thing!

Sandisk: “our sound fidelity isn’t perfect”

Some owners of the SansSanDisk Sansa Clipa Clip player from SanDisk noticed that it does playback of all songs with a minor pitch. Due to a flawed HW setup they don’t do a proper 44,100 Hz but instead 43,791 Hz (0.993 times the target value) or something like that. According to some sources this problem might be fixed in the Sansa Fuze players now.

Bugs aren’t really so surprising, perhaps what is surprising is that this bug has been around now for almost two years. To make matters worse, SanDisk now decided that due to them making cheap players people shouldn’t expect them to be very good sound quality wise and therefore they can simply not fix the problems:

due to trade-off decisions that were made in engineering these products to deliver superior consumer value at what we believe are extremely attractive price points, our sound fidelity isn’t perfect. We have re-evaluated the possibility of reducing the pitch variation and due to the engineering trade-offs the decision was made to stay with the current design. Very few listeners, however, have noticed or complained about it as an issue in actual practice.  For those who can detect sound differences with their naked ears during actual use and not via frequency analysis, our products may not be the best choice for them.

Clip owners out there now put their hope even more on Rockbox for Clip.


Firmware Hackers!

I fell over this job ad at LinkedIn that sounds like a perfect match to some of our existing Rockbox hackers:

Job Description

In this position, the individual will work on the common back-end architecture common for the SanDisk product line. The individual will develop the programming specifications, will explore alternate designs, and program, debug and deliver completed firmware. The individual should be fluent in programming in C language, familiar with assembly and Python scripting language programming and should have experience with hard drive or flash device firmware development. The individual will analyze, design, program, debug, modify software and troubleshoot code for firmware (IC embedded code) applications. Work often involves analog and digital hardware and software operating systems.

So send in your resume. And once you get the job, don’t be shy and let’s get Rockbox on some more SanDisk devices! 😉
