replicator.org ... incoherent code

So finally, I updated the homepage to work with drupal 4.5.0. The conversion of the stylesheet was a little more work than expected, and I am not satisfied yet. Expect some font/layout changes in the next few hours.

I have converted the pm3 (paramatrix) project directory from cvs to subversion . After having a little struggle with setting the appropriate user rights and finding the best method to invoke cvs2svn, I got a subversion project with all my cvs history entries (I would always suggest to invoke cvs2svn using --no-default-eol and --keywords-off).

Today – for the first time – I worked a few minutes inside the OpenGL terminal emulator, I have written for the paramatrix 3D server. Everything went ok, but at some time I missed the clipboard support a little.

I found a small problem with the vertical sync in multi-monitor environments using the current nvidia drivers. Probably I need to buy another PCI graphics card. For now, I switched vertical sync off to minimise the display output latency. It is definetly not a performance problem. Text drawing inside the terminal is always many times faster than realtime.

At the moment I am working at the focus-manager, to support the switching between multiple terminals. The next step is to create an OpenGL math library to simulate all the quaternion computations and associated matrix changes in the scene-graph.

Not knowing that this would cause some problems, I started to get a small fax server running in the office. We had a RedHat 9 server and a passive AVM ISDN card (Fritz PCI) available.

Accepting that the passive AVM cards need CAPI to receive faxes, I was surprised seeing CAPI support compiled into the RH9 kernel. The required binaries are found in the isdn4k-utils package (use them, not the ones coming with capi4-utils).

First you need to stop the ISDN service. Best use chkconfig --del isdn (if you use your isdn card to connect to the internet or as an answering machine, you are most likely get a conflict between these services).

The next step is to download the appropriate CAPI driver from AVM, they are available from their ftp-server, choose your card type and install the latest sources (I simply took the latest release for Suse 8.2, which seem to work fine for RedHat).

Install the kernel-sources package and the isdn4k-utils-devel and type make all in the driver’s source directory (the available install-script seems not to work on RH9).

Then copy the driver (here fcpci.o) to /lib/modules/<your kernel>/misc/

Now, CAPI needs to know what driver to use, edit /etc/capi.conf and prefix all lines with a '#' to comment them out and append one line with the drivers name and 6 dashes in the columns (probably this is different for your card).

Here is how it looks on my installation:

# card          file    proto   io      irq     mem     cardnr  options
fcpci           –       –       –       –       –       -

Startup CAPI using the command capiinit start (you are tainting the kernel right now, ignore it).

To make capi a permanent feature on your system, write a script to call capiinit start and capiinit stop.
