I was looking for the best way to convert pixelbased images to .eps fileformat to use them in my documents created with LaTeX. The problem was that the eps-files where always very big (from 40kB jpg to 4MB eps).
At first I found jpeg2ps which produces eps files in eps version 2 or 3.
Beginning with the second version of PostScript (PS) the PS-Interpreter can render jpeg-images which are contained in ps-files.
So the easiest way I found was to use 'convert' which should be available on the most GNU/Linux Systems.
convert test.jpg eps3:test.epsnote the 'eps3:' at the beginning of the output file.
This produces eps-files which are just minimal bigger the the original jpg-file.

Today I need this article about SpeedStep with Linux from the Intel site (I mentiond it already on my NX7000 Notebook site).
This is an really great source:
http://softwarecommunity.intel.com/arti ... g/1611.htm
I often need the commands to force my CPU to go down to 600MHz because sometimes my laptop is running without a reason with 1600MHz which makes my fan running all the time and that is really annoying.
By the way, my laptop died yesterday - I'm currently using my dad's laptop wich is the same model as mine so I had just switch the harddrive to bring up my system again.
When I was in University yesterday I started my laptop and the display flared - I thought it is flaring because I made a suspend to disk before (sometimes the display shows curious output for one or two seconds if I'm booting my computer after a powersave -U). So I removed the battery and restarted the machine but there happend just nothing - no display, no harddrive access ... NOTHING.
So I gave the laptop to the repair center of electronic market and now I hope that they can repair this defect.
Good Night (in Germany)

Tuesday, February 5, 2008, 09:15 PM - Linux, shell scripts
Today I made a little shell script to create the text-logos like the 'fancy text' image in this entry.
convert -fill 'rgb(128,128,128)' -background transparent -font FONT.TTF -pointsize 50 label:"EXAMPLE TEXT" -rotate 90 OUTPUT_FILE
-fill Color in rgb notation
-background Background color (here transparent background)
-font ttf-file (I think you can also use a system font).
-pointsize size of the text
-label:"" Text which appears in the image
-rotate Rotate the image
-OUTPUT_FILE filename of the output file
(here png because I use a transparent background)

I've read an article in the c't magazine and they said ubuntu is a real debian system with many user-friendly configuration-tools, so you can decide how much debian you want to use. I think this is an interesting aspect speaking for the ubuntu-system.
But the last time I tried ubuntu (a half year ago) I was not satisfied because I found some inconsistences. I changed my password with passwd in the comandline but the password for the gnome system was still the old one (I was really confused). But in the last few tests I read about ubuntu it performed pretty good.

A friend told me had installed Ubuntu on his Laptop and almost all features work out of the box.
3d-acceleration, display, wlan, mouse, speaker loudness buttons, cpu frequency scaling
I was surprised when I heard about this installation-success. It seems that Linux improved very rapidly during the last half year.
<My opinion>
I think it would have been better if Marc Shuttleworth didn't have developed his own Linux OS and develop directly for Debian because Ubuntu is based on Debian. So I think the community would profit much more if they develop new features together. So they don't have to invent the wheel new.
I've seen some programms in my Debian installation which are from Ubuntu so perhaps the two distributions run together.
</My opinion>

I set up an extra page for the Debian installation an a nx7000 here.
I installed debian etch via netinstal and made an dist-upgrade to sid.
Then i fetched the firmware (the driver has been instaled for default in etch) for the wireless lan card from ipw2100 an copied in the directory given in the documentation (/usr/lib/hotplug/firmware/ or /lib/firmware/ )and in the documentation are some important options for kernel compiling.
I compiled a kernel with help of debian-administrators and the options of the following intel article.
Really good article about Centrino Speedstep technology.
http://www.intel.com/cd/ids/developer/a ... .htm?prn=Y
Path where you can read and set the cpu-settings: /sys/devices/system/cpu/cpu0/cpufreq
Now I installed powersaved and kpowersave.
With aptitude install cupsys my Kyocera mita FS-1000+ works fine.
So far it's an pretty good linux (almost) out of the box.
the SD-card-reader
Here I found an interresting homepage: Winbond-howto
With
modprobe wbsd
modprobe mmc-block
it works
bluetooth (I don't testet it yet, perhaps it works already)
It works. But when I tried to compile the gnome bluetooth tool it wont work at all. (It's not available as an debian-package)
Things I'd like to work:
clone or enlarge the display (I've read this is possible with the X.org radeon driver or with an driver from ati)
The driver from ati wont work at my machine.
3D-acceleration
IrDA
special buttons (like suspend)
