Uzebox - AVR Gaming console | Håkon Nessjøen

http://lunatic.no/2013/08/uzebox-avr-gaming-console

Uzebox – AVR Gaming console. So lately, in my vacation time, I have been fiddling with Uzebox. It’s a game console from just a ATMega644 mcu and a AD725 (RGB-to-NTSC converter) chip. Thats the whole idea. The RGB signal is created by a manual 3:3:2 resistor based DAC, and audio is pure PWM signal. The project is now also supported well by a small but great community, that has helped Uzebox with more video modes, games, and even a realtime emulator! You can buy yourself a Uzebox at Adafruit.

DMX Light control system | Håkon Nessjøen

http://lunatic.no/2011/11/dmx-light-control-system

DMX Light control system. Every year, I team up with raider.no. To arrange a party in Hurdalen, or around the Oslo area. And one of the things that is important for us (especially me and William. Is to create a cool opening show, using our own innovative technology. We don’t have a lot of money in the organization, so we tend to also develop stuff that already exists. So we split up the task in two daemons and a GUI. The two daemons are written in C, and the GUI in Perl (using the Catalyst Framework).

Variable initialization in C | Håkon Nessjøen

http://lunatic.no/2011/11/variable-initialization-in-c

Variable initialization in C. I’m feel that I am starting to get the hold of C programming. But every now and then, I get these “ahaaa” moments, that I am a bit embarrassed about. One of these “aha”‘s I experienced today is how/when C handles initialization of variables where you don’t explicitly initialize them yourself. Posted November 13th, 2011 in C.

Where I talked about the MAC-Telnet client I created for Linux users. Since then, I have both started porting it to OS X and to create a daemon version of MAC-Telnet, called “mactelnetd”. You can look at the different branches at github.com. The format of /etc/mactelnetd.users is like this:. Users file for MAC-Telnetd. Haakon-kontorpc mactelnetd [.

Found my missing diskspace in Linux | Håkon Nessjøen

http://lunatic.no/2014/08/missing-diskspace-in-linux

Missing diskspace in Linux. Today I had a problem with a server that had no more disk space. And I learned something new in the process. Told me that 100% was in use. Which was about 29GB on that server. But if I checked the root partition with. I got about 9GB of used space. So off to checking where the space could have gone:. I know “du” does not take account for inodes, etc. But according to. My Inode size * Inode count = about 700MB. So that was not it. 8220;Hidden” directories under mountpoints.
