Ah, the wonders of e-commerce!

After excruciatingly long months of waiting for all pieces of the puzzle to fall into place, I am pleased to announce that the dayjob finally rolled out its very first online shop!

The process of putting this together has been quite an experience: I had to learn about the wonders of payment authorization gateways, different taxation jurisdictions, etc. For instance, we have to deal with 4 taxation jurisdictions:

  1. Estonian corporates and individuals: always add 18% VAT.
  2. Other EU individuals: always add 18% VAT.
  3. Other EU corporates: can be exempted from VAT, if their EU tax registration number is valid. Otherwise, add 18% VAT.
  4. Corporates and individuals from outside EU: always exempted from VAT.

As much as we looked around, we could not find any e-commerce site engine that can handle all the intricacies of dealing with EU corporate customers who may or may not have a valid EU taxation exemption number so, for now, our online shop only handles cases 1, 2 and 4 properly.

What can you find on our online shop?

  • Our acclaimed LTSP client hardware solution, the ThinCan.
  • Our really cool Programmable LPC Dongle, which is an Open Source tool for developing and debugging firmware running on devices attached to an LPC bus. I mentioned Open Source, because we publish the FPGA code and Python scripts needed to access the LPC Dongle under the LGPL.
  • Various other products which we happen to sell in the Baltic market.

Anyhow, I'm really happy to finally see this online shop deployed. So many people had wanted to purchase a ThinCan using a credit card or from countries for which shipping costs were difficult to determine and we unfortunately could not easily accommodate them. This is now resolved. Enjoy!

xf86-video-cyrix and xf86-video-nsc: it's dead, Jim

It had to happen sooner or later:

The X.org drivers for the old GX1 variants of the Geode chips formerly made by Cyrix and NSC no longer build against the current X.org release. Given the imminent release of X.org 7.4 (server core 1.5), this essentially means that users of older Geodes will have a nasty surprise, the day they upgrade to Ubuntu/Intrepid, which ships with core 1.5. Soon after, the release immediately following Debian/Lenny will be affected too.

There is a planned milestone to eventually reintegrate support for older GX1 products into the clean and up-to-date xf86-video-geode framework, but this will unfortunately come too late for those upgrading to Ubuntu/Intrepid, unless...

...unless someone volunteers to copy gx_* files inside xf86-video-geode and graft GX1 support into the resulting gx1_* files. If you have access to Cyrix/NSC GX1 + CS5530 or AMD SC hardware and a reasonable knowledge of the X.org codebase, your contribution would be most welcome.

O: planner -- project management application

This one had been a long time in the making, but here it goes: I'm orphaning Planner. Why? Because upstream hasn't been too active in ages, save from a few random bug fixes, and because the GCC 4.3 transition at Debian has exposed yet more bugs that make it FTBFS. The package had been marked as RFA for a while, but I decided that I'm not gonna wait any longer; O it is. Hopefully, an experienced GNOME maintainer will take over and revamp the upstream code into a usable shape. If not, then I guess we just found another dead package in the archive. So be it.

HOWTO build a clean LTSP boot image that includes the latest updates

Thanks to Oliver Grawert and Michael Haas for this idea!

  1. Check your LTSP server's sources.list

    Ensure that the server has the relevant APT sources to fetch the latest updates:

    deb http://security.ubuntu.com/ubuntu hardy-security main universe restricted multiverse
    #deb-src http://security.ubuntu.com/ubuntu hardy-security main universe restricted multiverse
    
    deb http://fi.archive.ubuntu.com/ubuntu/ hardy-updates main universe restricted multiverse
    #deb-src http://fi.archive.ubuntu.com/ubuntu/ hardy-updates main universe restricted multiverse
    
    deb http://fi.archive.ubuntu.com/ubuntu/ hardy main universe restricted multiverse
    #deb-src http://fi.archive.ubuntu.com/ubuntu/ hardy main universe restricted multiverse
    
    deb http://ppa.launchpad.net/q-funk/ubuntu hardy main
    #deb-src http://ppa.launchpad.net/q-funk/ubuntu hardy main

    In this example, the Finnish Ubuntu mirror for the Hardy suite is used. Change this as necessary. Notice that all source package lines are purposely commented out.

  2. Build a boot image using that sources.list

    Build the image using the following command:

    ltsp-build-client --copy-sourceslist --accept-unsigned-packages

    This builds the image using the repositories found in the server's sources.list. Accepting unsigned packages is necessary, because the PPA is not digitally signed.

The above method is a good way to check what would happen on a clean install, if any particular package were updated to a newer proposed release that is currently sitting on someone's PPA.

Enjoy!

HOWTO make Geode thin clients work on Ubuntu/Hardy LTSP

As summarized by Ace Suares, to validate my first rough upgrading instructions:

  1. Upgrade the packages in the LTSP chroot

    First become root:

    sudo chroot /opt/ltsp/i386

    Then add the repository, update and upgrade:

    echo "deb http://ppa.launchpad.net/q-funk/ubuntu hardy main" >> /etc/apt/sources.list

    apt-get update && apt-get upgrade && apt-get clean

    APT will inform you that some packages cannot be authenticated. This is normal, since the PPA is not digitally signed. Simply answer Yes.

  2. Purge the transitional AMD driver

    apt-get --purge remove xserver-xorg-video-amd

    Then, exit the chroot:

    exit
  3. Update the LTSP boot image

    sudo ltsp-update-image

    On a 64-bit server, the correct command is:

    sudo ltsp-update-image --arch=i386
  4. Profit?

Happy Midsummer, everyone!

xf86-video-geode: now with full OLPC support!

Freshly uploaded to Debian: xf86-video-geode 2.10.0. Asides from a slouch of bug fixes, this version finally includes complete support for features unique to the OLPX XO-1.

Enjoy!

Kuradne Geode draiveri!

Yes, another post about the Geode drivers. After much head banging, I finally figured out that the sloppy method used to generate the list of supported PCI ID for each driver in Debian and Ubuntu is what wreaked havoc with the GEODE driver:

  1. Support for the GX2 chipset was backported into the old NSC driver, which created a PCI ID conflict with the official support that is present in the GEODE driver.
  2. To make matters worse, that damn NSC driver also conflicts with the older CYRIX driver that supports earlier versions of the Geode chipset.

To fix both issues, I have produced new NSC and GEODE packages and uploaded them into my Ubuntu PPA for the Hardy series.

Tip: as soon as you have upgraded, purge the -amd transitional package; it only confuses the X server and disrupts operation if you leave it there, especially inside an LTSP chroot. If you were using a static xorg.conf, simply upgrade the Device line to use "geode" rather than "amd" and you're done.

After upgrading to these packages, normal operation should be restored for all Geode variants. As a bonus, X should now even be able to work without an xorg.conf (of course, with the wrong keyboard map, unless you live in USA) and in all known LTSP variants.

Enjoy!

updated ALSA driver for early PowerPC hardware

Risto Suominen contacted me recently, after seeing my Ubuntu wiki page where I try to document what works and what doesn't using ALSA on PowerPC hardware. He has developed a patch against the snd-powermac driver that mainly support 603, 604 and G3 PowerMac hardware, to implement better support for several old Mac models. He was wondering where he could find testers for his work, so I offered to blog about it here. You can find his diff and patching instructions on his website. You can contact Risto to report on your testing's result using firstname.lastname@gmail.com

Estonian ICT conference, March 18th 2008, TOBB Plaza, Istanbul, Türkiye

I previously wrote about my visits to Turkey to develop our export market in the Middle-East and how I ended up representing the whole Estonian business world in bilateral negotiations with Turkey. I'm going there again for two weeks, this time accompanied by a whole business delegation headed by Estonian prime minister Andrus Ansip.

Asides from various official events organized by our Turkish hosts to present Turkey to their Estonian guests, the crux of the visit is a conference hosted by DEIK and the Estonian embassy, on Tuesday, March 18th. The goal of this conference is to present Estonia's extremely advanced use of ICT technology in E-Business and E-Governance. Speakers from several private and public sector organizations will explain how they benefited from Estonia's hyper-connected lifestyle and, most of all, how this has made every Estonian's life more pleasant, because it offers a convenient way of performing a broad range of online transactions not just with businesses, but also with governmental organizations.

Yours truly will speak about the advantages Estonia offers to investors and technology freaks alike, from the perspective of an industry insider who, given the opportunity of choosing his first pick for a liberal high-tech nation, dropped the Nokiaesque lands of Suomi to go Eesti.

The morning of conference will end with a business lunch where interested Turks can network with their Estonian counterparts and create lucrative bilateral opportunities.

Space in the TOBB Plaza auditorium is limited so those interested in attending should promptly contact DEIK to get their name added to the guest list.

Turks interested in learning more about Estonia in their own language should visit estonya.net.

Rumor has it...

...that Skype might be willing to port the Linux version of their application to Pulse Audio, as long as they get all the help they need to make this a quick and painless process. Rumor also has it that yours truly will have a visit from a Skype insider tomorrow at 13:00 EET to discuss this issue and, hopefully, be in a position to point the insider to a member of the PulseAudio community willing to guide them through this process. Rumor also has it that volunteers who contact yours truly on time to announce themselves might improve this port's chances of actually happening.

Re: xf86-video-amd: patched xserver-xorg-core available

I previously wrote that:

The next step is to produce patches against the X server 1.4 in Debian/Sid and Ubuntu/Hardy, and then get the fix merged into the upstream X.org tree before X server 1.5 is released.

Good news: Bryce Harrington produced patched X server 1.4 packages for Ubuntu/Hardy!

The LTSP and OLPC communities are hereby invited to test this ASAP. If nothing major is reported, this will be become the standard X server 1.4 for the Ubuntu/Hardy LTS release, following which the patch will also be merged into Debian/Sid.

xf86-video-amd: patched xserver-xorg-core available

Great news: After several weeks of investigating, Bart finally figured out what made the driver for the AMD Geode GX/LX chipset fail on recent X.org servers: it turns out that, starting with X server 1.3, changes under the hood took place that affect a number of products booting off a General Software BIOS, making the whole hardware freeze as soon as a DDC probe is attempted. Bart promptly produced two patches against the x86emu component of X server 1.3 that fix the issue. Hurray!

Ubuntu/Gutsy packages of the patched X server 1.3, plus current AMD 2.7.7.5 drivers, are available in my PPA.

For Debian/Lenny, the same packages compile from Ubuntu sources as-is. Meanwhile, those of you running Debian/Etch only need to compile the Ubuntu sources for the above AMD driver against the X server 1.1 available in Etch.

This should finally allow people developing distributions for LTSP or for the OLPC to use standard Debian packages.

The next step is to produce patches against the X server 1.4 in Debian/Sid and Ubuntu/Hardy, and then get the fix merged into the upstream X.org tree before X server 1.5 is released. We're already working on it, but help is always welcome.

xf86-video-amd from OLPC not for public consumption

Holger reported in his blog that he uploaded a backport of the AMD Geode GX/LX X.org module to Debian. He also points out that what he has backported is from a non-Debian source. In case it wasn't obvious to him, there are good reasons why the official Debian module is not from the OLPC branch: the OLPC branch includes OLPC-only code that breaks operation for non-OLPC hardware. This means that the backport package is completely useless for the vast majority of GX/LX hardware on the market. Well done, Holger!

Hunting for a new laptop (part 2)

Earlier, I had reported on my quest for a new laptop. To recap, I had narrowed down my choice to an LG model whose 12.1" 1280x800 WXGA display and ATI Mobility Radeon X1250 graphic chip failed to be recognized by the Ubuntu CD. Back then, my initial tests were performed using a Feisty CD. Since then, I have returned with a Gutsy CD and got equally disappointing results: E: screen found, but none offers a usable configuration.

Some people suggested buying a laptop with an all-Intel chipset. While Intel chipsets are indeed the best-supported in the business, largely because Intel invests its own resources into coding Linux drivers for all of its products, products based on Intel chipsets tend to be double the price of those based on VIA motherboards with ATI graphic chips. Seeing how quickly hardware devaluates on the market, it feels rather unjustified to pay such a fortune for an Intel-based product, only to see its market value cut in half less than a year later.

Here's a tip for AMD/ATI marketroids: invest as much resources into coding GPL kernel and X.org drivers for all of your products as you did for the OLPC project and always do so a good 12 months before entry to market. Otherwise, prepare for bankruptcy, because companies like Intel who don't shun the Linux market will eat you alive.

Me goes back laptop hunting...

O: planner -- project management application

While looking at outstanding bugs against my Debian packages, I noticed that an RC bug had crept in against Planner. The bug itself isn't new. In fact, Ubuntu had experienced it already and simply decided to build their package without SQL support to resolve the issue.

Planner is a fairly well-matured piece of software, with very few bugs remaining. It remains quite usable in everyday use. However, it has fallen behind in terms of keeping its code up-to-date against the latest versions of some optional dependencies.

Tonight, I was just sitting here pondering what to do and it occurred to me that I'm simply no longer interested in maintaining the package. I have done a fairly good job of overhauling the build scripts and of upgrading them for the Python transition but, at this stage, I feel that I've accomplished as much as I could do. Besides, I no longer have the time to maintain so many packages, so I have decided to focus on maintaining those I actually care for and Planner isn't one of them.

The package already is assigned to Debian's GNOME team, so no need to actually orphan it, since anyone from the team can pick it up. If you're a member of the GNOME team and feel like taking over, perhaps even submitting patches to upstream to close a few more bugs, go right ahead and jump in.

Valga - Valka : 1 linn, 2 riiki - 1 pilsēta, 2 valstis

Thursday evening, I joined the inhabitants of the twin town of Valga-Valka, sitting smack on the Estonian-Latvian border, to celebrate their entry into the Schengen treaty. Ever since I first crossed the border there on a roadtrip from Tallinn to Fallingbostel, in year 2001, I knew I would have to return and, sure enough, I briefly passed through during last summer with an Estonian friend, on our way to an acquaintance's birthday party.

Still, that told me nothing of the town's life and left me wanting for more.

Upon hearing that year 2004 EU accession countries would join Schengen in December 2007, I immediately promised myself to show up and join the crowd. As it turns out, I missed Aleks Tapinš of the All About Latvia blog by very little, having I caught his last-minute e-mail the next afternoon. Aleks blogged a great article depicting the Latvian side of life and providing some background info on the town, if you're curious.

I arrived late-evening on Thursday via the Tallinn-Viljandi-Valga bus and checked into my hotel, then proceeded to checkpoint Valga II around 23:30, with the intention of grabbing a drink on the Latvian side and returning just before midnight for the celebrations. Hardly anyone was in sight, except for Latvian officer Čabana who was completing the inspection of a Russian car with three noisy passengers. Upon presenting her with my passport, officer Čabana cheerfully lead me to the office and slid my passport through a slot to officer Bukss, who was visibly surprised to have any tourist show up on the last day of his job to get their passport stamped. Upon explaining to him the reasons for my presence, he pointed me to a nearby bar where I could have a drink, visibly amused by the situation.

I spent the next few minutes in a local casino in the company of three hilarious Latvian truck drivers, Zintars and Aivars, two Latvians with limited English language skills and Yuri, an ethnic Russian living in Ireland who was born stateless on the Latvian side of the town and who later acquired Estonian citizenship by claiming ancestral land on the Estonian side.

Upon returning to the border, just minutes before midnight, I found myself in the middle of a huge crowd of villagers, police officers, border guards and politicians from both countries - barely getting noticed by anyone. I handed my passport to an Estonian border guard who emotionally commented to a civilian friend of his nearby that, "Wow! That was the last one!", handing me my passport back just as the midnight bells rang and the mayor of the Estonian side started his speech amidst pyrotechnics lining the road.

I then had a chance to chat with the Estonian mayor, who promptly handed me a bilingual certificate, signed by the mayors of both towns, attesting that I was the first to cross the open border, while introducing me to his two young daughters with whom he was about to take a stroll on the Latvian side.

The next morning, an even bigger and more symbolic event took place: the demolition of the fence that had been cutting the Sõprus/Raiņa street in half. You can see a picture of what the street looked like before on Aleks' blog article [edit: or on Jens-Olaf's blog article]. After the fence was removed, it instead looked like this:

The crowd then proceeded to checkpoint Valga III, where a stage had been setup for the politicians to make their speeches. An interesting fact is that, because of the way the border was drawn, along a creek leading to Pedeli river, an Estonian main road was technically on the Latvian border and thus aptly named "Raja" (border) street. The Estonian mayor commented in his speech that the the brand new supermarket standing behind us was also technically on borderland and could not have possibly been built earlier, weren't it for the Schengen treaty matter-of-factedly eliminating borders between participating EU countries. The speeches were closed by a youth group whose choreography featured six break-dancing boys, dressed as Estonian and Latvian border guards and as border posts. The choreography ended with the teenage border guards carrying away the human posts on their shoulders, just as a choir of young girls replaced them with songs in either languages.

Before catching my bus back to Tallinn, I dropped by the Valga tourist info, only to face a nervous-looking Kapo officer in plain clothes. Upon mumbling something about the tourist info and wanting to grab maps, I noticed that a press conference was taking place behind. As he finally let me pass to the tourist info side of the building, a familiar voice said to me, "Hey! Weren't you at our place last summer with Martin Ranna?" Yup, the wife of the acquaintance whose birthday party I had attended last summer is working there and greeted with me refreshments and munchies she had cooked in prevision for the presidential visit! As was my luck, she had one of the commemorative plaques that had been given to the politicians at Valga III on hand:

I was glad to see the town becoming one again, even though it is ethnically divided. There are already signs of people on both sides learning one another's languages and shopping on either side of town, not to mention plans of merging the municipal bus operations of the Estonian and Latvian halves of the town, so I'm sure that they'll get there in due course.

For me, Schengen brought a much more practical and quite welcome change: the end of messy border crossing stamps that were rapidly filling my almost new passport, every time I visited the head office of our company in Tallinn. While Estonian border guards mostly stamp passports in an orderly fashion, being careful to fit exactly 8 stamps in a single page and to put entry and exit stamps side-by-side, Finnish border guards apparently are incapable of doing so, instead systematically wasting pages by either stamping sloppily in a way that makes it impossible for more than 4 stamps to appear on a given page or by flipping to a brand new page, every time I had to cross the border.

In case anyone ever wondered why I'm currently representing Estonian interests abroad, despite living in Finland, this example is one of the many reasons: Finnish authorities routinely display arrogant carelessness towards the population and doubly so towards immigrants. It amounts to an accumulation of idiocy that has costly consequences on people's lives. For some, it's about being denied the public institutions' support when they need it the most and their life forever going downhill thereafter. For me, it has been about countless missed opportunities (jobs, love affairs, travel plans), plus very costly passport and residence permit renewals. Given this, I simply don't see myself ever representing Finnish interests ever again. Faith no more. Besides, the Estonians are fun and easy-going people. Siski ma mõtlen, kas ma peaksen nüüd Eestisse kolima või?

Ubuntu on an LG E200 laptop?

As my aging ThinkPad is starting to show signs of an impeding retirement, I recently began looking for a newer laptop to replace it. My current choice would be for an LG Electronics model E200-A.CPPPV laptop. However, when trying an Ubuntu Feisty live CD on it, X failed to find any usable screen resolution and aborted. Thus I was wondering if anybody had better results using a Gutsy CD? In principle, the hardware should be supported, since it's all Intel and ATI components but, these days, you never know, especially with graphic and wireless chipsets. Comments?

Miscellanea

Things have been rather hectic lately, so I haven't found much time to blog. Here's why:

DBE62

The Gigabit Ethernet version of our thin client took more time to produce than I expected, for a number of reasons mostly related to a few improvements we decided to squeeze into the design at the last minute.

However, today, we finally reached a point where LinuxBIOS runs as well as it did on our previous DBE61 model and where we no longer need any DOS tool to flash the MAC address into the VIA velocity Gigabit chip we selected. Hurray!

Production will only commence in one month, but I'm already excited by the new model's potential, both as a thin client and as an embedded platform.

Another good thing is that, thanks to Ubuntu developer Scott Balneaves, we managed to get all the necessary tools to support thin clients based on LinuxBIOS into LTSP, so our Etherboot model works out of the box on Ubuntu, since Gutsy. Hurray!

There is one remaining issue related to recent changes in X.org core functionalities that make the AMD driver we need unstable but, again, various AMD, Debian and Ubuntu developers are looking into fixing this, so we should soon have spotless Geode support into Debian and Ubuntu again.

Türkiye

I visited Turkey twice over the last few months, because I'm putting together a pilot project to better promote the Estonian high-tech sector abroad, in collaboration with the Estonian government.

I have to say that the more I visit Turkey, the more I like the place and the more understand why these people see themselves as Europeans because, you know what? They are: practically every significant civilization and religion that is at the core of European culture had major events taking place in in Anatolia or Thrace and, also, a devastatingly huge percentage of the consumer goods sold in Europe are designed and manufactured in Turkey.

Learning the rudiments of Turkish has also proven to be a lot of fun. While I'm nowhere near as fluent in Turkish as in Finnish or even in Estonian, the learning curve isn't as steep as I initially expected: Altaic and Ugric languages share a surprising amount of grammatical concepts, while Turkish itself borrowed a lot of vocabulary from French, because the founder of modern Turkey, Atatürk, was very fond of the language. I'll venture that proximity with nearby Middle-Eastern countries that were formerly under French influence has something to do with it too.

Identity crisis

To me, the most challenging part of these business missions abroad is to represent a whole economic sector from a country of which I'm not a citizen or even a resident. Case in point:

Being invited to dinner by a Turkish investor, I noticed the waiter asking my host where his foreign guest might be from. A few minutes later, as the waiter put down a gigantic pita bread with the word "Estonia" spelled in roasted sesame seeds, my host asked, reading my business card:

  • Actually, your name doesn't sound Estonian. France?
  • Québec.
  • And your mobile number ... 358 ... is that Finland?
  • Yup. I've been living there for the past 10 years.
  • Ah! So you don't live in Tallinn?
  • Nope. Helsinki.

Looking at the waiter and pointing at the gigantic pita, he continues:

  • Actually, make that Canada ... no, Finland ... Ah, sorry, never mind. Just keep it as Estonia.

Honestly, trying to keep a straight face while saying "We" about a country of which I'm not a citizen and where I don't even reside becomes unbearable. At some point, some European bureaucrats will have to admit that I need a new citizenship, to reduce the confusion and to let me find myself a proper national identity again; the sooner, the better.

Besides, the absurdity of the situation keeps on jumping at everyone's face: during the second mission to Turkey, I kept on bumping into Finnish diplomats who took personal offense at me for living in their country and yet representing the interests of a competing, neighboring country. If you ask me, I cannot entirely blame them for it.

However, as far as I'm concerned, I've done my homeworks: I've been here 10 years, I speak the language and I don't have a criminal record. Given this, you'd think that acquiring citizenship would be a mere formality, but the Ulkomaalaisvirasto doesn't see it that way.

If you ask me, this country's very first Minister of Immigration, Mrs.Astrid Thors, ought to unilaterally grant citizenship to anyone who's lived here for at least 5 years, just for the asking, regardless of what circumstances brought them here or of what absurd decisions the Ulkomaalaisvirasto might have previously made on their residence permit status. Doing this would go a long way towards undoing the mess of her predecessors at the Ministry of Interior and it would speak volumes about how much Finnish society has evolved from the days when any foreigner was a commie they had to push over the Eastern border.

Sound editors that work with Gstreamer or PulseAudio?

Today, I wanted to edit a few MP3 files into suitable ring tones for my phone. The idea seemed simple at first: load up a song, chop off a few bars and loop that as a ring tone.

Nice in theory, except that sound editing software on a free desktop is challenging, at best: most of it was designed back in the days of OSS and GTK 1.2, some wants to use JACK for playback, while the most recent crop indeed supports ALSA but insists upon having exclusive access to the ALSA device.

Dammit! My understanding was that, with Gstreamer and PulseAudio, the free desktop had finally acquired a comprehensive, standardized sound framework, but not many applications seem to support it — or is there something I have missed?
