In preparation to our trip to the glacier in Sölden in two days I made our snowboards yesterday ready for the snow. In April I covered them with hot wax and now I had to remove the excess wax.
The first step was to remove the excess wax with my scraper:
The second step was to buff up the base using a brush:
Then I used a cloth to polish it up:
The last step was to sharpen the edges with a special edge tool, which makes it pretty easy. Although I am not really convinced that the result is as good as I want it to be. I will know more in two days.
On the 5th and the 6th of October our mirror server transmitted about 4.5TB per day due to the OpenSUSE 10.3 release and during the last two days the amount of data transmitted was over 5TB due to the Ubuntu release. I am curious to what the release of Fedora 8 will lead.
Das unpersönliche Reflexivum erweist in der Tat noch zu Zeiten der Ohnmacht wie der Barbarei als Kulmination und integrales Kriterium Kritischer Theorie sich.
Yesterday David told me about
dedicated and that they
have released a new snowboard movie: Hunt & Gather. Usually I do
not watch many snowboard movies, but right now is just the perfect time of the
year. I am already waiting that it finally gets colder (at least in the
mountains) and in about two weeks the season will start for us in S

SLOF.
In theory building SLOF is pretty easy. After having downloaded it would basically be not more than extracting it and typing make, if there had not been the binary only part. So for having a working firmware for JS20 or JS21 following steps are necessary:
$ tar xzf slof-JX-1.4.0-0.tar.gz
$ tar xzf slof-JX-1.4.0-0-oco-gcc412.tar.gz
$ cd slof-JX-1.4.0-0-oco-gcc412
$ $ ./install-oco.sh ../slof-JX-1.4.0-0
Copying oco files to SLOF tree at ../slof-JX-1.4.0-0... done
$ cd ../slof-JX-1.4.0-0
$ export CROSS="powerpc64-unknown-linux-gnu-" # cross compiler or
$ export CROSS="" # native compiler
$ make -s
******** Building js2x system ********
====== Building slof ======
====== Building rtas ======
====== Building clients ======
====== Building boot_rom_js2x.bin ======
====== Building boot_rom_bimini.bin ======
This leaves two firmware images (boot_rom.bin for JS20/JS21 and boot_rom_bimini.bin for Bimini) which can be flashed on the target system. The next entry about SLOF will contain information about how to flash SLOF on a JS20 or JS21 with a slight chance of success.
The main reason for the open source release of SLOF is the
PPC970MP based reference design workstation (Bimini).
Bimini is a 4way PPC970MP based workstation and more information
about it can be found in Hugh Blemings’s Blog (here and here) as well
as in the press release
on power.org. In Hugh’s Blog not all details
are 100% accurate but he is pretty close.
The goal for Bimini is to have a 100% open source firmware without any
binary code required. The current release still consists of a part available
as source but there are still some small parts released as binary only. These
binary only parts are needed to get this SLOF release running on JS20 and JS21
blades. The communication between SLOF and the service processor on these
blades is the part which is available as binary only code and this will
probably always stay that way. Without this code it would not be possible, for
example, to power down or to reboot the machines which is not really necessary
for a working blade but one important step during the boot of the firmware is to
disable the watchdog or else the service processor would reboot the machines
after a few minutes and then it would be unusable.
Since Fedora 7 you can just install Fedora using SLOF without any additional
hacking required. SLOF pretends to be Momentum,Maple compatible and
this is supported since Fedora 7.
OpenSUSE should also support SLOF since 10.3 although I must admit that I
have not tried it since a few months. At least it used to work after I
contacted the openSUSE developers and after they fixed their installer to
detect it correctly. But my main focus is to always make sure that the latest
Fedora version is still working with SLOF on JS20/JS21/Bimini and Fedora 8
Test 3 works without any problems. My focus on Fedora is also the reason that
if you will ever see a Bimini demo system the chances are very high it will
run Fedora. I also tried Ubuntu some months ago but the kernel does not even
boot and as nobody cared about my bug report I am not really interested
investing more time.
Finally it happened. We (at IBM) have finally released the source code
of SLOF (Slimline Open Firmware). It took us only about 10 months to get all
the required clearances to publish the source code.
SLOF is an IEEE-1275 (Open Firmware) based firmware and is currently used
in most Cell based (IBM) systems and also in PowerPC 970 based systems. This
release is part of power.org’s PPC970MP based
reference design (Bimini). In addition to support Bimini it can also boot the
JS20 and JS21 blades.
Nearly all of the code is available as source code except for a few small
parts which are currently only available as object code.
So if you have a JS20 or JS21, are really adventurous, are looking for an
open source firmware, are ready to run without a hypervisor or you are just
interested in looking at BSD licensed firmware source code… download SLOF
at developerworks:
Much more information about SLOF will follow in the next few days.
It looks like it really happened. I am so excited.
