[linux-audio-dev] [RFC] Request For Contest - The Linux-2.6 theme song contest !

by Robert Jonsson

Hi Everybody, This mail is a direct consequence of the song Austin Acton posted recently. :) A nice little tune made with linux, about linux, that has been quite successful with very little advertisement. After a few brain rotations (before you ask, yes, I think by rotating my brain) I came to the conclusion that RIGHT NOW is a wonderful time to start a write_the_best_linux_song_contest! My reasoning is that linux-2.6 is just around the corner, people are hungry for any kind of linux related information, no matter how far fetched (I don't even think this is very far fetched). Making a little contest to choose THE linux-2.6-theme-song seems like a very good way to attract some easy publicity, the main thing we want to do is make people interested in (and aware of) audio production under linux. I'm confident that Slashdot (or any news site in the free software world for that matter) would gladly do a story on this event. BUT before we get to that, let's atleast produce some music ! :) Some criteria I thought would be applicable: - The song must be about linux in some way (about linux 2.6 seems the obvious choice). - The song must be (atleast) processed with a computer and that computer must run linux. - No computer running an operating system that is nonfree can be used in the production. (External synthesizers or similar stuff with advanced capabilties don't count as computers and can thus be used) - The song must be written by the artist (possibly used with permission). - The song would preferably contain some kind of voice track ( it might be hard to hear that it's about linux otherwise, and it would be nice to know how you people sound :-) - the better the audio quality the better, though I think there are other qualities of the recordings that count. - Some info about the applications/gear used should be included (atleast applications). - No prices, just free publicity for anybody that joins, and most publicity for those that reach the top in the event that we actually pull of a vote. We already got one song, Austins! I'm in the middle of producing a naive electronic piece myself (I mainly play the guitar) that I think will be applicable also. But... two songs don't make a contest... So, what do you say? Are we up to it? I'm calling all linux-artist wannabees, this is the time! I dare all developers that aren't on a deadline to take some time of from coding and also participate, bring out the artist in you! :) Wouldn't you just die to hear "The ballad of Alan Cox", or "Linus' Theme" or "The Bitkeeper Blues" :) (those are free btw if anyone gets any bright ideas ;) >From now til, say, December 14, one month, might be enough time to do something creative, yes? Let me know if there is any interest for this then I will try to formalize things a bit, website etc. Well don't just sit there, let's do it! :) /Robert

[linux-audio-dev] Oss & threading -- is it possible

by hexe_2003＠directbox.com

Hello ! I've read somewhere that it is not possible that threads write different data to /dev/dsp. But how does Cheesetracker, for example, make it then?

[linux-audio-dev] [CODE RFC] redefining sched_setscheduler using LD_PRELOAD

by Roger Larsson

Hi, (Jack O'Quin got me thinking about rt_monitor again - thanks!) This is an alternative to capabilities / SCHED_SOFTRR... I use my old rt_monitor * protects the system on RT overload * performs the actual setting of scheduler type * it does not even have to be visible for lusers! My old testprogram RT has been converted to a library fit for preloading. It works like this. As root start # rt_monitor As normal user start latencytest $ ./rts path/to/latencytest none 2 128 10 rts has two options -i do not raise the priority. -v be more verbose. * It does also limit the effective min/max range. Do also try (don't try this as root unless rt_monitor is running) $ ./rts path/to/latencytest none 2 1024 99 * In this case rt_monitor captures the process and renices it. (SCHED_OTHER + nice) BUGS: * better build and installation system * could ignore RT processes already running when rt_monitor starts * rt_monitor functionallity has not been reverified... * it can't lock memory :-( No PIDs in calls. * code that checks uid before using the redefined functions won't work (I have an modified latencytest) * client get stuck if there is no monitor running. /RogerL -- Roger Larsson Skellefteå Sweden

[linux-audio-dev] Re: Programming resource question

by vanDongen/Gilcher

Excellent plan. Maybe I could contribute, since I was thinking along the same lines as well. My performance system is a pd pattern sequencer triggering csound, also geared to my personal setup, and I have been thinking on moving it to C as well. Parts are already coded in C as a pd external.
