Platforms and tools

The events that made me create my homepage are explained in the history of this site.

Development tools

Most development tools that I use are from the GNU Tools suite. For graphical user interface programming these days I use the open source software Qt.

My typesetting system to create all sorts of papers, mathematical or others, including letters, is TeX. I use the TeXLive distribution on my GNU/Linux and Windows systems.


Linux penguinThe only working experience that I have with Linux are the distributions Slackware (1996-2000) and Debian (since 2001). When I started with Linux in 1996, slackware was a widely available distribution and for four years I managed to stay away from other ways of setting things up. Late in 2000 I was convinced of the convenience of debian by an expert.

My first Linux installation in October 1996 has been Slackware 3.0 with Linux Kernel 2.0.0 on the (now defunct) Aptiva Server sentinel. It has since then been upgraded several times up to Slackware 3.4 with Kernel 2.0.30.

The next installation (March 1997) was to put Slackware 3.0 on my ThinkPad, which was a model 755. I only had a 200 MB partition on a 1 GB disk – which was plenty of space at that time. A special challenge with that TP755 was an inverted diskette signal – a problem fixed thru the very beneficial communication in the Linux newsgroups (where I learned about the magic keyword floppy=thinkpad).

The installations on my next ThinkPad 760ED have been several Slackware releases and, in 2001, Debian 2.2 (‘potato’) with Kernel Version 2.2.17. This was also the Linux installation on the next ThinkPads X20 (April 2001-December 2001) and T22, upgraded to Debian GNU/Linux 3.0 (‘woody’) with the 2.2.20 kernel in August 2002. I had to re-compile the tiny editor ‘tc’ of Tim Baldwin, as Tim’s precompiled one was linked to the previous version of the ncurses library. This editor is my favorite one. Then, there have been other upgrades to kernel 2.4.18-1-686. After I bought this machine from IBM in December 2004, Windows XP was installed for some years, but since July 2008 it is again a pure Linux machine.

Since October 2007 I had a Linux installation on my client machine amalfi, which a year later – after some disk swapping – became my Linux server inuksuk; it is now running under Debian 8.5 GNU/Linux kernel version SMP Debian 3.16.7-ckt25-2+deb8u3 (2016-07-02) (jessie).


As of November 2013 my Windows client on nunavut has an AMD Fusion A4-5300 APU with Radeon Graphics (Trinity) at 3.4 GHz, running under Windows 7 Home Premium and since 2015 under Windows 10.


For 15 years (1988-2003) I used OS/2 on some machine – more on OS/2 platform.
