This morning, at about 7am UTC 10 machines running Fedora Core 7 all locked up. They were on a private network inaccessible to the general internet. The lockups were all complete: not even Caps Lock on a connected keyboard worked (a good sign of kernel death). Rebooting and checking the logs gave no information: the last syslog entry was sometime after midnight and was normal. Once restarted (with a hard reset) they all seem to be functioning normally. I don't know yet what caused the lockup.
It's as if a million Fedora boxes cried out in terror and were suddenly silenced...
A major problem with non-linear models is that one can get stuck in a local error minimum of the solution. To get out of these minima, one needs to seriously perturb the model parameters. In a genetic algorithm this is done by mutations.
This is incorrect: mutation fulfills a very different function. The crossover operator allows intermediate solutions to be generated which will hopefully break out of local minima. Genetic algorithms and genetic programming are population-based optimisation methods: the initial population will hopefully span the entire search space. Thus by generating intermediate solutions we will break out of local minima. Mutation is usually (in sensible GAs) small scale, and consequently causes us to search the area around current solutions. If mutation is too large then the algorithm becomes random search.
Micheal Whitmore doesn't say whether, by free, he means no-cost binaries or open source. Linux's key strength is not it's lack of cost to download, but rather the availablility of its source code. Without this key distinction the article is meaningless.
...Corel thinks Linux's future is in the sub $500 computer...no evidence is given for the price cutoff.
It's economics: if you're pricing a computer at $500 then suddenly the software cost is a large chuck of the total price. Using a free OS is probably going to double your profit margins.

Indeed, it's the known bug in 2.6.21 as mentioned on the debian lists: http://lists.debian.org/debian-user/2009/01/msg00006.html
So now I know, thanks slashdot!
I'm a sysadmin for a small data centre.

..just use esound. All the lag you ever need.
Seriously, check the esound sources for the esddsp program. Modify it so it uses a large buffer, then run it on your radio app. 20 minute job.
