I’m off to Galway for the weekend. There’s going to be a gathering of Linux people at Galway University on Saturday morning, as well as a night out that night. Alan Cox should be going as well as most of the Linux guys in Ireland. Look for a report next week! I got an interesting email during the week concerning real-time processes, and another subject upon which I’ll base a quizlet soon.27

I received an email from Tim Newsome yesterday. He talked about giving a demo real time priority so it could execute smoothly. I would have agreed with him a few months back but I believe Linux is capable enough to handle the strain of a demo without resorting to giving it (the demo) complete access to the CPU. Hardware prices are dropping every day, and entry level machines are now much faster than the machine I work on at home(or at work..) I want to see demos running on an X desktop. Maybe, with a slightly higher priority than other […]

Let’s get things moving shall we? In this tutorial I’m going to move that white dot we drew in the last tutorial around the screen! The dot will follow coordinates generated by the sin and cos functions. #include <math.h> #include “ptc.h” const SPEED=50; const WIDTH=320; const HEIGHT=200; class Move_dot {   private:     typedef struct count     {       int x;       int y;       int xdir;       int ydir;     } count;     int32* sin_data;     int32* cos_data;     int frames;     count current_pos;     count last_pos;     int dir;     int last_counter;        void update_counter (int* counter, int* dir)     {       if (dir[0] == 0) {         if (counter[0] < 1024) {           counter[0]++;         } else […]

DemoNix moving to lowrent.org was mentioned on Orange Juice! (thanks doj of cubic!) PHP/MySQL is lovely. The link for the PC Demo FanClub was wrong in the last update! Update on Jan 1, 2008 lowrent.org and ojuice.citeweb.net are both gone!

On the day Slashdot links to my page on Xoom the server decides to crash! Demonix is obviously now at lowrent.org. Now to stop all that spam from Xoom… A new version of install-mail will be released soonish, but I guarantee nothing! Check the “Linux Demo Ring” below. There are now 3 sites! The PC Demo FanClub has moved yet again. Jer is also looking for people to provide content for his site. Click on “Join the Club” on his page for more details.
