My Linux-experience

I have been using Linux (mostly in a dual-boot environment) since around 1996 or 1997 (Cheapbytes CD from Lehmanns bookstore with Debian 1.24 on a Pentium 133 MHz).

The most recent version of this page has been created with Linux tools alone and is hosted on a Linux box. Some images and older sediments of my site may incorporate Windows-generated images, but nowadays I have switched to Open Source tools to create everything I want to show here.

Until recently I have been developing Web-based applications on Linux- and Apple-machines, using Mozilla, PHP, Perl, Python, PostgreSQL, MySQL and Eclipse to program distributed bioinformatics database-applications.

Beside that I was heavily depending on a stable machine to do my Ph.D., which was one of the two main reasons for switching from Windows NT to SuSE-Linux and finally Fedora and Ubuntu.


Because people always want to see screenshots here are some of my home-desktop. They are slightly recursive, the first one shows an editing-session of this HTML-page, running SuSE 7.3/KDE 2.2 with an IceWM-theme, the second one shows the upload of the homepage, running SuSE 8.1/KDE 3.0 with the Quartz theme and some nice tools. The third one is SuSE 9.1 KDE 3.2.1 and Gimp 2.0 the next is from the Fedora Core 3 installation on my AMD Athlon64 running Gnome 2.8 followed by a few shots from the FC6 install with 3D effects enabled. Next Fedora 10 Linux and Fedora 13 Linux and CentOS 6 and currently Ubuntu 14.04 LTS Desktop. Apparently I like blue backgrounds...

Raspberry Pi

I got a Raspberry Pi 4 with 2 GB RAM as a gift. Of course, I have to find some useful project for this little machine.

Read my Raspberry Pi project page for this.

Installing Linux on Laptops

Recently, I bought a used Lenovo Thinkpad x230.

Read the review.

During my work for Exelixis, I had an IBM R32 laptop running SuSE 8.1 and during my stay back at the university, I had a Toshiba M30-344[pdf-file], which I used with SuSE 9.0 and 9.1.

Short note: Both pages will not get updates, as I don't own those laptops any more.

Blue pill or red pill...

Gentoo Linux on Small Systems

Installing one of the more recent distros on an old system (aka my 300 MHz PII) is not really fun.

Except for the fact, that a small hard disk is quickly filled up by a load of gunk you might not need at all (but which is installed anyway, if you don't select rpm-packages by hand), those distros tend to be painfully slow (the current version of Quanta IS dead-slow even on my AMD Duron 700 (yess, CPUs have arrived ad 6.0 GHz meanwhile, I know)), and take eons to load the desktop (why? I was running Linux on my 486 ages ago).

There seems to be no real hope for a fast-and-small version of SuSE, therefore I had to look for something else.

Enter Gentoo-Linux: (I have to admit, that almost everything which follows, has been stolen from an email I got from a friend, who setup all this on his machine ;-)).

Anyway, if you are interested in my installation-notes for a small-footprint Gentoo-system, read on.


Several years ago I switched from my long-time favorite Linux-distribution to Fedora Core 3.

Installation notes for Fedora Core 3 Linux

Permian period. My first stab at Fedora Linux after I switched from SuSE. Quite some manual effort here compared to more recent distros.

Installation notes for Fedora Core 6 Linux

Jurrassic age. One of the more unstable Fedora releases.

Installation notes for Fedora 8 Linux

Stone age. A better one (compared to the previous install).

Installation notes for Fedora 10 Linux

Very outdated. Some major havoc with Sun Java. Apart from that, the install becomes more and more boring mainstream

Installation notes for Fedora 13 Linux

Outdated. New install, new glitches, among them one, which cropped up in the current Ubuntu install.

Installation notes for Fedora 14 Linux

The last Fedora. I switched to CentOS afterwards.


Installation notes for CentOS 4.3

Some time ago I had to setup a 64-bit 4-way server and decided to give CentOS a shot. Having ordered a floppy-drive ("who really needs that nowadays") immediately paid off, because the RAID-Controller was not recognized and a newer kernel-module had to be installed from a boot-floppy (not a problem, unless you can't use one).

Installation notes for CentOS 6.2

After everyone decided, that the new GUI for Linux should look like a Smartphone, I moved from Fedora to CentOS 6 (which also has a longer life-time and does not force you to install a new OS every 1,5 years or so).

Ubuntu Linux

Installing Ubuntu 7.10

Read my review on installing Ubuntu 7.10 Gutsy Gibbon. I did this recently for one of my older machines, because the old Ubuntu-version was no longer supported.

Installing Ubuntu 12.04 LTS 64 bit for XBMC

I have built a XBMC based Home Theater PC (HTPC) using Ubuntu 12.04 LTS 64 bit on an Intel platform.

Read my XBMC HTPC installation notes.

Installing Ubuntu 14.04 LTS 64 bit

My last PC died from Capacitor plague after more than 6 years, so I had to buy a new one. CentOS 7 was not quite ready, so I choose the new Ubuntu LTS. Read my Ubuntu 14.04 LTS Desktop installation notes.

Upgrading to Ubuntu 16.04 LTS 64 bit

As the update client kept nagging me, that a new version is out, I followed that advice and updated the existing system to Ubuntu 16.04 LTS. Read my Ubuntu 16.04 LTS Desktop upgrade notes.

Upgrading to Ubuntu 18.04 LTS 64 bit

I did an upgrade to Ubuntu 18.04 LTS. Reading my Ubuntu 18.04 LTS Desktop page is worthless, as it is empty (nothing to fiddle around with there).

Upgrading to Ubuntu 20.04 LTS 64 bit

I did an upgrade to Ubuntu 20.04 LTS. There is nothing to read there Ubuntu 20.04 LTS Desktop.


Doom 3
Quake 4
X-Plane 8.40

There are some decent games out there, which run natively on Linux (see above :-) ).

With Steam-support the number of games natively supported on Linux has been quite OK recently, although some already wrote it of and -of course- many block buster releases are Windows (or console) only.

Running Windows games on Linux is mostly not fun, so I ditched that and run Windows games on Windows nowadays.


And of course, there is that other Linux computer, I carry around.
