Nearly two years ago I wrote about end of Zaurus production. This news ended on many websites around the globe (mostly without quoting source). But it was not end — Sharp was producing Zaurus clamshells from time to time during those two years.

In December 2008 there was another set of news that Sharp ends Zaurus production. This time it looks like real end. Marc from TRISoft told on OESF forum: “Last production run was March 2008. And we’re now out of stock with new units. Looks like it’s now really over and out.”

I ended my work on Zaurus machines about year ago. OpenZaurus was ended, I had job to do and other devices to support. But still from time to time I used my c760 for some debug sessions (usually in cases where QEMU was not enough). With serial cable and wifi card it was good substitute of developer board.

Today I got Atmel AT91SAM9263-EK board. Will work on it on Monday and it will be my main testing/development platform for some time. Probably next will be BeagleBoard or other OMAP3 based device.

Today I talked with Dodji Seketeli about misc things and noticed that I started 10 year of using Debian GNU/Linux.

First attempts were on my Amiga 1200 equipped with Apollo 1240/40 expansion board (I had 32/48/64MB of RAM on it) and Fast-ATA controller. After installation of “slink” I was playing with system and then moved to “potato”. In Polish Amiga magazine “eXec” I put my article about installing Debian on Amiga systems and also updated “potato” official installation guide. Those were crazy times. All I had was VGA mono text console because running X11 on AGA graphics chipset resulted in very slow display so it was unusable for any serious use. But I learnt lot of things which I was not able to learn on my user accounts on misc x86 Linux boxes. For example with my friend we connected his Commodore 128D via serial line and used to do email/www/irc from it (via serial->ssh connection).

It was also first time when I used cross-compiler — I used PentiumII based Linux machine to build Amiga (m68k) kernels. It gave nice speedup (also due to much faster harddisk interface).

In 2001 I sold my Amiga system and moved to x86 land. Here amount of available Linux distributions was much wider (for Amiga/m68k only Debian was available) but as I knew Debian I decided to stick with it. After years I have to admit that it was one of my best decisions when it comes to computers.

I even used Debian on 386sx based PC with 5MB of memory — it was nice terminal to my main box :)

Why Debian and not Red Hat/Mandriva/LFS/Gentoo? I think that this is due to DFSG and that license stuff is very good solved. As a result I do not have to check license of application if I want to hack it. I only need to check does it is in “main” part of repository.

OK, some people can say that Debian has very long release cycle… But I use “sid” (aka “unstable”) not releases (aka “stable”) so the only thing which touch my systems is sometimes lack of newest software (but usually it lands in “experimental” branch).

2008 is ending. As before it was very good year. I have very nice daughter, our family has new flat. My company has clients with interesting projects.

January

• Bought Nokia N810 tablet. Had to do this in UK store because Nokia does not sell them in Poland.
• Released “Hrw Big blue” — my version of “Big blue” WordPress theme. No support any more for it as I stopped using it.

February

• My daughter Mira was born — she is cute ;)
• I bought car — Opel Astra combi 1997 is more then enough for us.
• Donated my old collie to Thomas Kunze to help improving Linux 2.6 support on this small beast.
• Created Polish regional settings package for Maemo OS2008. It also shown some bugs in Maemo itself.
• Wrote my palmtops story which require updating as I have few devices more now.
• Offered Zaurus c7x0 leather case for free. No one wanted it ;(
• Wrote few WordPress plugins: Recent Comments and Meta — I still use them.

March

• Poky Linux 3.1 (codename ‘pinky’) was released. I am providing support for systems based on it.
• IPKG finally died so we switched to maintained OPKG tool to manage packages.
• Cursed a bit during testing of Maemo media players. Recently I tried few more and still use default one.

April

• First April post about moving to London got amazing response. But it was only joke.
• Got N800 emulation working. Too bad that I was not allowed to distribute “config.mtd” file which made it possible. Later I discovered which flag needs to be reset and added N810 emulation infos.
• Created Polish keymap for QWERTY keyboard of N810 — thanks goes to Jiri Benc for his “ukeyboard” package. No thanks goes to Nokia Maemo team for not making it easy.
• Wrote what do I think about Maemo closed components which makes this nice device not so nice.
• Wrote how to make BitBake based builds faster — handy on multi-core systems.

May

• I was on LinuxTag 2008 in Berlin. It was great to meet friends again. Thanks go to Zecke as he provided me free tickets and sleeping place. I still have working liquid powered clock which I got there.
• Replaced my desktop with new one — it is nice to have more CPU power especially when lot of builds needs to be done.
• Defined myself as developer not programmer
• Tried to use N810 for car navigation and failed. Bought TomTom One few months later (works great).

June

• Played with connecting USB devices to N810 tablet — all thanks to USB gender changer adapter which I got from Keesj during LinuxTag.
• Started wondering which phone to choose as next cellphone — now I know that next will be Symbian (Nokia E71 looks very interesting as phone).
• Again was hit by crappiness of ATI RS48x graphics chipset — now this is not my problem as I added NVidia Geforce 6600GT inside and gave whole machine to my youngest brother (it replaced 5 years old AthlonXP desktop).

July

• I had 0x20 birthday — got awesome present from friend — puzzle with C code which rendered picture with greetings.
• GUADEC 2008 was great event. Istanbul is nice city worth spending more time. But at least I visited some places ;)
• Wrote a bit about using Poky SDK to build software — this apply also to any OpenEmbedded based SDK of course.
• Also wrote about packaged staging and what it gives — generally it can speed up repeating builds. I used it to make “build each recipe from scratch” builds of Poky — lot of dependencies were added into recipes as result.

August

• Intel acquired OpenedHand — I got job offer in UK but decided to not move. It was nice to visit London again, too bad that I lacked time to see anything (as usual). The whole trip was crazy (have you ever travelled on the night bus standing for 4 hours straight?)
• We visited my parents and I was asked (again) what exactly I do for living. So I answered and my mother understood.
• I resolved problem with Nokia N8x0 tablets emulation — one flag needs to be unset to make Maemo boot in QEMU.

September

• We moved to Szczecin, Poland — new flat == separate room for my work.
• Maemo Summit — nice event, lot of Maemo developers/users, met old friends, gave presentation about Maemo in QEMU emulation — people asked questions, I tried to answer.
• As my company ended second year I decided to drop “HaeRWu” part from it’s name (it was too hard to pronounce for people).

October

• End of my work for OpenedHand — it was good time and I miss atmosphere of that company.
• Started working as contractor for Bug Labs Inc. company - their device is interesting. They use Poky ‘pinky’ as base of their system.
• OpenEmbedded project migrated from Monotone to GIT so I started to merge interesting things from Poky (lot left still to merge).
• As one of good things in OpenedHand was buildbot I decided to start my own one on home machine.

November

• Unpacked Progear webpad to check how recent kernels work on it and update it’s configuration in OpenEmbedded a bit.

December

• Moved to juszkiewicz.com.pl domain — it was 2rd domain change since I started this blog. All old addresses redirect to proper one.
• Bought tickets and hotel reservation for FOSDEM 2009 event — I missed 2008 one due to birth of Mira.
• Got Koala MiniPC 2PCI case for Alix 1c board — need to buy proper PCI riser and it will be my new router.
• Got BUG device from Bug Labs Inc..
• My working space was invaded by Poky beavers.

On Thursday I got package from DHL courier (one note for future: if you need to send me something by courier service avoid Fedex). Inside was nice box with BugLabs logo.

After unpacking I got BUG, or to be more precise:

• BUGbase
• BUGview module
• BUGmotion module
• VonHippel module
• BUGlocate module
• external antenna for BUGlocate GPS
• power supply
• SD->microSD adapter
• 2GB microSD card

This is how modules look:

VonHippel is interesting module as it gives access to I²C, serial, I²S, DAC, ADC, GPIO, SPI, power signals. It is named after MIT professor Eric von Hippel (because he thought of it!) author of “Democratizing Innovation”. This module allows to connect just about anything electronic to the BUG. Interview with professor can be seen on BUG Blogger website.

Size is comparable with Nokia N810 tablet. Would be nice to get 800x480 screen for BUG (i.mx31 has OpenGL acceleration).

This is usual configuration when I work with device (just screen and VonHippel):

There is 64MB of flash in device but by default it boots from microSD card (2GB one was in package). This allows for easy rootfs tweaking/updating. Kernel flashing takes lot of time but we plan to work on other methods of booting kernel.

With all modules plugged in it starts to be thick… You can notice 4 function keys on left side, joystick and button on right and monochrome screen between. By default it shows clock and icons of plugged modules but with joystick some system menu can be used.

Whole device is powered by BUG Linux which is based on Poky ‘pinky’ release with some updates. Access to all modules is only from Java at that moment. But that not mean that it is closed device — everything in BUG and its modules is open and free. There is a WiFi module (not released yet) which uses chipset from “libertas” family (same family as the one in OLPC).

I am curious what will future bring for this tool.

Today my workplace was invaded by beavers. But they are not normal beavers but Poky Linux ones.

At the beginning there was just one of them — he came and checked clock to know which timezone is in use here:

Few minutes later his companies arrived and synchronized clocks:

After few minutes they invaded my working place…

Good that they are friendly and came to help me support Poky Linux based systems :)

Today I got case for Alix.1c mainboard. For reminding: this is PC Engines board in mini-ITX format, powered by AMD Geode LX800.

Package arrived from Koan Software and contained one of their products: MiniPC 2PCI case.

Package contents

There were many addons in the box:

• 60W 12V AC adapter
• 2.5” ATA -> Slim DVD/CD adapter
• PCI riser for 2 slots
• wall mounting elements
• 2.5” ATA 3.5” ATA adapters
• bracket for 3 DB9 connectors (additional serials anyone?)

AC adapter is added because case contains small PSU with few connectors. I do not use it because Alix.1c mainboard consists similar one already (and lack ATX power connector).

Inside view

Inside case there is a lot of space available:

There are mounting places for 3.5” HDD, 2.5” HDD and slim DVD/CD drive (signal adapter attached). There are also 2 fans (60mm each) but I left them not connected (Alix does not require cooling and lack sockets for fans).

Front panel

Front panel has 2 USB sockets, HDD and power leds and power button. As usual in mini-ITX cases there is no Reset button. Not present in my case (but available as option) is CompactFlash slot accessible from front. I did not ordered it because Alix has such one integrated.

Summary

Case is very high quality made — no sharp edges, easy access to all peripherals. And all those addons which are in a box makes overall cost smaller. If someone is searching for good mini-ITX case then MiniPC ones are good choice (and there is smaller version without place for PCI cards).

PCI 3.3V :(

As I wrote before I plan to make router based on Alix.1c — but after putting it into case I discovered one problem with board itself. It has 3.3V PCI slot so I have no use of PCI riser which was added to case. Will search for VIA one because it is universal (3.3V/5V) so I will get slots (but have to remember that cards have to accept 3.3V signals).

Few months ago I decided that after 2 years of “HaeRWu Marcin Juszkiewicz” company it is good time to drop first part. The reason was simple — “HaeRWu” is hard to pronounce for English speaking people (and not only them). And I think that I am more known as Marcin Juszkiewicz in community then by my company name.

As next step I bought “juszkiewicz.com.pl” domain for all of my private and company things. And today moved this website to new address. Old ones will work of course — they redirect to proper one.

All email addresses will work too.

I already bought tickets for bus to/from Berlin, planes tickets and booked room in Astrid hotel.

The plan starts on Thursday with Berlinia bus from Szczecin to Berlin Schoenefeld (SXF) airport. Then Easyjet flight number 4701 (16:00) to Brussels (BRU) and from there to Astrid hotel. I will do return trip on Sunday — Easyjet flight number 4702 (20:50), then bus to Szczecin.

So if you want to meet me before FOSDEM crazy time you can catch me on Thursday evening or Friday (rather morning as I plan to do walk around a bit to see something other then hotel and conference).
