Claes at foss-magasin.se asked a bunch of questions about me, my commitments within the FOSS community and related matters recently over email. This Swedish interview just now went public: Daniel Stenberg – cURL, Rockbox och FOSS-Sthlm.

For my international friends who don’t understand the Swedish: I am quite happy with the questions and being allowed to answer them at this lengths etc, so I am considering doing a full translation of it and posting it at a later date.

Now, when we’re slowly approaching two years it is time to look back and what we’ve done during the past twelve months and what we’re doing right now.

We have firmly established ourselves even more as expert developers within embedded systems. We’re over and over again being hired by the teams that themselves are hired by companies to provide services or products. During the last twelve months, we’ve written software and software designs for a huge medical equipment company, a small video equipment manufacturer, a major international telecom, a market-leading embedded systems provider and a global chip manufacturer. We’ve debugged simulation software, designed video streaming servers, done video subtitling magic, poked on Linux kernel code and we’ve done old-school 8051 and 16bit x86 assembly. I’ve also managed to do a Embedded Linux development (in user-space) training course – twice. All this, in just the past year!

Haxx was (and presented) at FSCONS in Gothenburg, we went to (and presented at) FOSDEM in Brussels and we went to the Rockbox devcon in London. We did lots of work within the foss-sthlm community.

Oh, and we’ve revamped our logo and graphical design.

Haxx consists of three full-time employed senior expert embedded systems consultants. We’ve all been in the industry for over twenty years: Daniel Stenberg, Björn Stenberg and Linus Nielsen Feltzing.

We continuously work with partners in the area to reach out to new and existing customers. As we’re very small and rather spend our time on working in our actual assignments we appreciate the help with sales and marketing. If you’re in the Stockholm area and ever end up needing devoted and skilled embedded software hackers, call us!

I’m gonna do my very best to make sure we get another great year! I’ll report back and tell you how it went.

Rex, Anja, Agnes during our summer vacation 2011.

The importance of private computer backups has only increased over time, as these days most of us have vast amounts of family pictures and videos stored as well, things that in the old days were stored (and lost) separately.

A growing problem with remote backups is of course that we all have ridiculous amounts of data to backup. Getting a commercial remote backup deal for say 300GB (and growing) isn’t cheap. And we’re also very often at loss when it comes to get a solution that works on Linux.

In Haxx, we also recognized and suffered from these problems. We came up with a scheme to fix a distributed networked backup among ourselves! Getting large hard-drives to use locally is fairly cheap. We all have fairly good fixed-fee no-bandwidth-limit internet connections (although admittedly the uplink speeds are lacking for us typical ADSL users).

We decided that among us 4, each of us gets an account at two of our friends’ servers and we’ll be able to upload our backups to those at our own pace to store whatever we want. We decided on getting two places for everyone to decrease the risk even further, especially if you for example urgently need to get something back and one of us have a network problem (not completely unheard of) or something else.

My current total backup is about 100GB and I have a 1mbit uplink. If I use the entire bandwidth for this, other things get a little sluggish so I’ve capped the rsync job to 90KB/sec… My first run thus completed in roughly 13 days. Luckily I don’t add contents at a very high pace so the ordinary sync jobs from then on should be much smaller and should be able to complete within hours. As long as I add less than ~3.5GB during a 24 hour period, it should be able to keep up to sync to two remote places.

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.

Recently we have refreshed our logo design, and subsequently we’ve now also refreshed our web site to use this new look and design that already have influenced how our presentations, business cards and more look and will look in the future.

When I say “we” did it, there should be little surprise that we did engage with someone else to do this for us, since all of us at Haxx are quite incapable of doing designs that look tasteful.

We’re quite happy with the new look. We like the cool blue colors. More machine, less human, less colorful. This logo should also work slightly better in grayscale than before and getting rid of the border will also make it easier to use on various merchandise.

Robin with git

Robin Rosenberg started off the sessions by telling us about git and related dives into JGit, EGit, gerrit, code reviews and Eclipse. Robin is a core developer in the EGit/JGit projects. While I think I know at least a little git already, Robin provided an overlook over several different things in a good way. (It should be noted that Robin was called in very late in the game due to another talker having to drop out.)

As a side-note, I will never cease to be amazed by the habit in Java land to re-implement everything in “pure Java” instead of simply wrapping around the existing code/tools and leveraging what already exists and is stable…

Jonas with patents

Jonas Bosson spoke about the dangers with software patents and how they are not good, they’re hindering innovation and cost a lot of money for everyone involved. He also pledged the audience to join FFII to help the cause. You can tell Jonas is quite committed to this subject and really believes in this! And quite frankly, I don’t think a lot of people in this surrounding would argue against him…

Andreas with Meego

Andreas Jakl, just arrived from a rainy Helsinki, then told us (in English while all the other talks were in Swedish) about how to develop stuff with Qt for Symbian, Meego or desktop using the same tools. He showed us the latest fancy GUI builder they have called Qt Quick and how they use QML to do fancy things in a fast manner. He also managed to show us the code running in simulator and on device. Quite impressive. Andreas is a very good speaker and did a very complete session. As a bonus point, he used ‘haxx.se’ as test site for demonstrating his little demo build and of course you can’t help loving him more then?

Johan with Android

Johan Nilsson started off just after the coffee break with educating us how you can do push stuff from your server applications to your mobile device. How it works and how to control that in various way. Johan’s presentation was into details, in a way at least I really appreciated it, and his (hand drawn on paper then scanned) graphics used in the presentation were stunning! The fact that Johan sneaked in a couple of curl command lines of course gave him bonus points in my mind!

Henrik with Fribid

Henrik Nordström took the stage and briefed us on the status of the Fribid project, which is a very Swedish-centric project that works on implementing full Linux support for “bankid” which is a electronic identification system established by a consortium of Swedish banks and is used by a wide range of authorities and organizations these days. The existing Linux client is poor (and hard to get working right), closed source, saves data encrypted with private hidden keys etc.

Food, Talk, Tablets

In the restaurant after the seminaries, we gathered in a basement with beer in our glasses and chili on our plates and there was lots of open source and foss talks and we had a great time and good drinks. Two attendees brought their new tablets, which made us able to play with them and compare. the Android Samsung Galaxy Tab and the german Meego based WeTab.

To me there really wasn’t any competition. The Galaxy Tab is a slick, fast and nice device that feels like a big Android phone and it’s really usable and I could possibly see myself using it for emails and browsing. It was a while since I tried an Ipad but it gave about the same speed impression.

The WeTab however, even if it runs a modified Meego that isn’t “original” and that might suffer from bugs and what not, was a rough UI that looked far too much like my regular X Window system put in a touch device. For example, and I think this is telling, you scroll a web page down by using the right-side scroll bar and not by touching the screen in the middle and dragging it down like you’d do on IOS or Android. In fact, when I dragged down the scroll-bar like that I found it far too easy to accidentally then press one of the buttons that are always present immediately to the right of the scrollbar. Of course, the Galaxy Tab is a smaller device and also much more expensive, so perhaps those factors will bring a few users to WeTab then still.

I don’t think I’ll get a tablet anytime soon though, I just don’t see when I would use it.

Summary

I didn’t do any particular talk this time, but I felt we had a lot of good content and I can always blurb another time anyway. I really really like that we so far have managed to get lots of different speakers and I hope that we can continue to get many new speakers before we have to recycle.

It was a great afternoon and evening. All the good people and encouraging words inspire me to keep up my work and efforts on this, and I’m now aiming towards another meeting in the early 2011.

I will do another post later on when the videos from these talks go online.

The history of Haxx goes far longer back than so. Linus Nielsen Feltzing and I first registered the company Haxx back in October 1997 and we used it then primarily as a way to market and do business on the side of our “real” jobs. To have a way to charge and do things we wanted to, that wasn’t conflicting with our day jobs. And of course we also bought the domain and could setup our “permanent” email addresses etc, which turned out great since I’ve thus used the same email address since back then and I hope I never need to change it again!

The first year of Haxx has been nothing but great fun and a major success.

As we’re contract developers and consultants, we of course need to make sure that our employees are sold to customers to a high degree with as little gaps as possible. Our projects are typically going on from a few months up to a year or two. During this year, both me and Björn have worked with several end customers and we’ve thus both managed to change assignments several times and none of the times caused any gaps – at all. Our services seem to be in high demand.

Being only two employees brings challenges on how to deal with sales, financial accounting etc as we’re just a few guys and we’re experts on development! We have found a few great partners that “sell” us (and of course we pay them a certain amount of percentage, but that’s a price we need to accept and is nothing but fair anyway since we can then remain doing what we’re good at and what we love) and we’re buying the bookkeeping etc from another company that is specialized at doing it for companies like us.

We’re looking forward to many more years of great fun. We also hope to be able to grow the company slightly over time, so if you’re a kick-ass embedded open source guy with networking experience and some 10+ years in the business and you live in the Stockholm Sweden area, do get in touch! As I’ve mentioned before, we’re gonna start out our second year with Linus onboard.

I’ll get back with an update next year!

We have teamed up with a bunch of friends here in Sweden that share a lot of our mindset and spirit, and together we’ve created Fossgruppen, The Foss Group, and as an umbrella organization the group is all about making it easier for companies and people in Sweden and the world to find open source professionals. We offer open source consultants, foss-related training/courses and more.

If you’re looking for Open Source professionals in Sweden, no other company or association can compete with the amount of experience and core hacker geekness that Fossgruppen possesses. Together we also have contributors and maintainers of a range of foss projects. If you have any insights at all into foss in Sweden, there is no doubt that you will recognize more than one name in our group.

The guys in Fossgruppen are also involved in some of the biggest recent foss-related events in Sweden: foss-sthlm and FSCONS.

Fossgruppen currently consists of this team of elite guys:

• Daniel Stenberg
• Björn Stenberg
• Simon Josefsson
• Henrik Sandklef
• Jonas Öberg
• Johan Thelin
• Henrik Nordström
• Andreas Nilsson
• Jeremiah Foster
• Mathias Klang
• Peter Stuge
• Marcus Rejås

The web site is basic so far, and we don’t really have a shiny logo to show off with yet but I’m confident we will sort all that out over time!

Snaxx-23

Haxx happily invites you to waste an evening by talking and drinking at October 18th 2010 with us and friends in our spirit.

[ we should get ourselves a snaxx logo, so if you're reading this and have some talent consider yourself wanted and appreciated! ]
