How to recode AVI-files to be able to write them to a Video CD. ffmpeg -i original.avi -target pal-vcd copy.mpg vcdimager -t vcd1 -l "Title" -c vcd.cue -b vcd.bin copy.mpg cdrdao write --device /dev/cdrw vcd.cue Note: vcdimager is able to take multiple .mpg files as argument, very useful when burning multiple family videos to the same disc! Tip from Johan Risberg on how to be able to reattach a UTF-8 Linux screen session from Cygwin.

Netork Programming -- Link Collection

February 10, 2009 - 1 min read

This is a first effort at collecting information about network programming structs and APIs available in UNIX. I plan on updating this as I find more. Linux Journal: Linux Network Programming, Part I, II, III. Linux Journal: Multicast Routing Code in the Linux Kernel Linux Journal: Inside the Linux Packet Filter, Part I, II /usr/include/netinet/in.h There are of course, in addition to these fine sources, the entire catalogue of work by Richard M.

Minix editline v0.3.0

February 8, 2009 - 1 min read

It’s here! Fresh, new and packed with new features! Well, really just one new major feature — support for ANSI arrow keys. A good enough reason to bump the minor version number :-) Get it from the usual FTP location: http://ftp.vmlinux.org/pub/People/jocke/minix-editline/

The joy of colors

November 9, 2008 - 1 min read

Ever so often, as I have mentioned before, I lose myself in trying to find new ways of working and doing my daily tasks. One such digression is the topic of editors. I mainly use GNU Emacs for development and other major tasks, for everything else I use Vim. Vim is quick to start, capable, good looking and easy to use, contrary to other vi implementations. (Most notably nvi, which I hate with a passion!

Minix editline v0.2.2

November 8, 2008 - 1 min read

Oups, it seems I forgot to announce the v0.2.2 release of the Minix editline library! It was made official in Bazaar over a month ago, 2008-10-02, but it was not until today that the tarball was created and uploaded to the FTP. The most noteworthy in this release is support for command completion with the addition of rl_complete() and rl_list_possib(). Two function pointers that easily can be overloaded by the user.

Ubuntu 8.10rc1 — NetworkManager WTF?!

October 27, 2008 - 1 min read

I tried upgrading from Hardy Heron to Intrepid Ibex this weekend. Big mistake. If I disregard the total dpkg meltdown that I, as usually, had to resolve manually there still remains this recurring madness called Network Manager. I’m an engineer. I have a masters degree in computer engineering. I have worked professionally with GNU/Linux since 2000 and been a die hard user of it since I left OS/2 behind in 1996.

Cross Compiler Foo

August 20, 2008 - 2 mins read

There is a certain magic surrounding cross compilers and the people that know how to build one. Not unlike that of (Linux/BSD) kernel developers. At work we today support two embedded Linux targets, both are ARM based, and in neither of the two have we built the cross compiler ourselves. The first was ye’ old 2.95 based from uClinux.org and the second we had a consultant build for us. Lame!

Moving to ISC

July 30, 2008 - 1 min read

I hereby announce that all of the code I produce from now on will use the ISC license. Previously I’ve used the MIT license and the GNU GPL, or LGPL where applicable. The reason for changing this is two-fold. First, I like to be able to reuse much of what I do in proprietary settings. Yes, I’m one of those people who look upon the world with “grey” eyes rather than black & white.

Link Collection w31 2008

July 30, 2008 - 2 mins read

George Dyson, son of legendary Freeman Dyson, talks about the first computer, the first software bugs (both physical and logical) and the initial struggles of hackers. Fun history lesson for computer engineers and programmers alike. (Now, go crawl the web for “Dyson Sphere” and “Star Trek”! :-) Is Ubuntu 8.04 really that buggy as everyone suggest? My guess is that we’ve reached a breaking point where beginner users (< 1 year) are starting to outnumber the older “hard core” users.

HowTo: Build GNU Emacs from CVS

July 28, 2008 - 1 min read

Why would you want to do this? Well, considering all the neat new things that have been added lately it should be tempting for any old Emacs fan. The Emacs Wiki has all the info you need, but here is a quick run-down of the bare necessities. Start by checking out your working copy: cvs -z3 -d:pserver:anonymous@cvs.savannah.gnu.org:/cvsroot/emacs co emacs cd emacs/ ./configure make bootstrap Start with ./src/emacs or symlink the binary to your ~/bin/ directory.
