It seems crazy to me that Omnom takes up so many resources. Many websites I've been to have shoutboxes and don't seem to have any issues running them. Perhaps if Omnom(is rewritten) or a successor is written a more simplistic approach would be best.

I've been thinking about adapting my node.js chat server for a while now. I've already got an irc bot that supports multiple servers and channels. The chat server itself has built in support for channels that I haven't implemented. I know that the chat server itself doesn't take up much ram and there is a lot of optimizing that the irc bot code could have. The irc bot also would take a lot less memory if it was only on one server instead of 2 or more. Each new server it is connected to adds a forked process.

OmnomIRC was coded in a way that it arrives on Omnimaga as soon as possible back in 2010, with only like one hour of free time every week. Once Netham45 had vacations, he completely recoded it, but it did not let enough time to make it 100% perfect. It has more features than SAX but it never got the chance to even get close to being as optimized as it, since SAX has been maintained for over 7 years.

Omnom is way more optimized than it used to be, though, and NEtham45 had done a good job so far. Hopefully it can be improved even more or something based on it can be done (especially now that the source code is public).

I haven't fixed the issue with my bot, but I've done two things to mitigate this issue:
1) I wrote a little daemon called CPUHero that kills any processes that eat up lots of CPU. When the bot dies, it (usually) gobbles CPU because it's stuck in a loop. (I'd appreciate any help with that!) Therefore, it should automatically get killed.
2) Sometimes, it doesn't trigger CPU usage. I wrote a quick web interface (inside CPUHero's interface) so that you can restart the bot! :) For security reasons, 3 people must click the button within 5 minutes to trigger a restart. (Don't abuse it!) Go here for the button: http://withg.org/albert/cpuhero/

Note that this ONLY applies to my alternate New bot. I have zero control over Netham45's "New" IRC bot.

For convenience, I've also placed the link in my sig for easier clicking. :)

Again, it's:

Since OmnomIRC has troubles with auto-restarting/connect, wouldn't it be a bad idea to kill it when it takes too much resources?

I will not deploy CPUHero on the server that runs OmnomIRC until I implement non-killing for limiting CPU usage.

Ok good to hear. Limiting CPU usage (and RAM) would be a better idea I think.

I'm now enforcing CPU usage with CPULimit, which is a pretty safe tool. :)

To be honest, I don't think CPUHero is *that* bad. It gives the process a chance for "redemption" (less than 80% CPU usage). See below:
Code: [Select]
[Mon Oct 22 15:26:57 EDT 2012] [CPUHero] [Redemption] Society is rather peaceful... there are no trouble PIDs to redeem!
[Mon Oct 22 16:18:07 EDT 2012] [CPUHero] 6258 (php5-fpm) gets a PID_TROUBLE score! Process 6258's CPU usage was over 80! (CPU usage: 88)
[Mon Oct 22 16:18:07 EDT 2012] [CPUHero] Commandline for 6258:
[Mon Oct 22 16:18:07 EDT 2012] [CPUHero] User: www-data
[Mon Oct 22 16:18:08 EDT 2012] [CPUHero] 6258 (php5-fpm) now has a PID_TROUBLE score of 1, out of 3.
[Mon Oct 22 16:18:13 EDT 2012] [CPUHero] [Redemption] 6258 is on its way to redemption!
[Mon Oct 22 16:18:13 EDT 2012] [CPUHero] [Redemption] 6258 now has a PID_REDEMPTION score of 1, out of 3.
[Mon Oct 22 16:18:19 EDT 2012] [CPUHero] [Redemption] 6258 now has a PID_REDEMPTION score of 2, out of 3.
[Mon Oct 22 16:18:24 EDT 2012] [CPUHero] [Redemption] 6258 now has a PID_REDEMPTION score of 3, out of 3.
[Mon Oct 22 16:18:30 EDT 2012] [CPUHero] [Redemption] 6258 now has a PID_REDEMPTION score of 4, out of 3.
[Mon Oct 22 16:18:36 EDT 2012] [CPUHero] [Redemption] Probation is over! 6258 now has a PID_REDEMPTION score of 4/3 - it's now free!
[Mon Oct 22 16:18:41 EDT 2012] [CPUHero] [Redemption] Society is rather peaceful... there are no trouble PIDs to redeem!
(Yes, I was bored when writing this - you have to make the output somewhat interesting, right? :P)

Therefore, if there's any CPU usage spikes, no killing will occur.
(Then again, if OmnomIRC gets used constantly, then that's another story...)

Well it looks like that for Late October and most of November, the rising popularity of Nspire Linux and especially the TI-84 Plus C Silver Edition announcement has helped boosting activity a lot. Earlier this Fall, some people were mentioning that most people had less school work starting in November and that this would help, but sometimes Thanksgiving drives a bunch of people away or they go less active for some reasons anyway, yet this month there are 1400 more posts than October.

Hoping that the 84PCSE brings interesting opportunities for BASIC, ASM and hopefully Axe programmers when it comes out (unlike the Nspire). Just remember the 84+/89T craze back in 2004, and that wasn't even a color/resolution upgrade (although back then cellphones and handhelds were not as fierce competition towards calcs as they are today).
