Fujitsu Esprimo C5730 with "Blauer Umweltengel" / GreenIT

Fujitsu Esprimo C5730 running Ubuntu 9.10

I'm currently testing a new computer for a friend from Fujitsu. I recommended the model C5730 because it's smaler than usual micro-tower and it's quite a representant of so called "green IT". For example it carries the German eco label "Blauer Umweltengel". I think, only Fujitsu certifies some of its products for this label.

 

Power consumption in idle is about 30 W. During video sessions it's about 50 W. That's all.


Preinstalled is Windows 7 Professional. My friend needs windows for his business-software.

Just to test, I droped in the current Ubuntu CD (9.10) and it starts perfectly with it. Even the sleep mode works impressingly.

LaTeX Font Selection

Recently I redesigned my default letter template in latex. I use the scrlttr2 package from the koma-script suite. In some .lco-file you may adjust a lot of settings.

But how to change the default font? And which fonts exist by the way?

First of all, I installed the texlive extra fonts:

 

apt-get install texlive-fonts-extra

 

In your document you select now the fontpackage if there is one. E.g.

 

\usepackage{charter}

 

And/Or you change the default font family:

\renewcommand{\familydefault}{bch}

 

Sometimes you have to do both. But who wants to read the manual for every font. Only to see, that this font is absolut awful...

 

The FontCatalogue on www.tug.dk helps you very much with the selection. You see for every font the syntax to include it and some text written with it. Perfect! Have a look at:

Google Chrome for Linux speeds up Typo3 Backend

Last week, I read the september issue of the Linuxjournal about the Google Chromium development and I was happy to find a development linux version online.

 

With this version installed in debian stable and testing, it is now possible to write fluently text into the Typo3 htmlarea RTE!

Even with the speeded up version 3.5 of Firefox this was awful on slow computers like my VIA Epia EN1200 or even on the J8F9 Jetway board.

 

So I am very impressed about the Javascript speed of Google Crome (current version is 4.0.249) and I will use it at least in the Typo3 backend.

 

The development tools are not that impressive. So stay with the perfect FirefoxFirebug combination.

Get Rid of "wlan0_rename" by iwl3945 Driver on Debian Lenny

I'm working from time to time with my three year old Samsung Q35 laptop with Debian stable installed all the time. So at the moment, it's running Lenny.

 

Usually, I'm too excited about new kernel features and bugfixes and don't wait for the next debian release but compile the kernel myself. That's what I'm used to do for plenty of years now.

 

My system is running now with current 2.6.31.5 kernel and uses the iwl3945 driver for wifi. But one point was always annoying to me: The wifi device was called "wlan0_rename" and sometimes it started with "eth2"! And that's the p oint: when it started with eth2, I had to reconfigure /etc/network/interfaces (stupid) or reboot and hope for wlan0_rename (stupid as well).

 

Today, I started to google the solution which is quite simple thanks to two threads/bugreports:

In the file /etc/udev/rules.d/70-persistent-net.rules, I changed the following lines:

 
# PCI device 0x8086:0x4222 (ipw3945)
#SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:18:de:87:f3:b9", NAME="eth2"
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:18:de:87:f3:b9", ATTR{type}=="1", \
KERNEL=="wlan*", NAME="wlan0"
 

 

And wow! It starts _always_ with wlan0.

 

Thanks to the original poster and to this bugreport.
