I am using a distributed continuous integration tool which I have written by myself in Ruby. It uses a fork of Mike Perham's "politics" for distribution of the tasks. The "politics" module is using threads for the mDNS part. Every now and then I encounter a core dump which I don't understand: *** glibc detected *** ruby: double free or...

Hi, after posting a question related to nginx, I'm a bit further with my investigations: The problem is, that the merb framework timeouts after about 30 seconds. If i tell the underlying nginx-server not to timeout, merb does, and I can't find a way to tell it not to; I need to do requests that take up to some minutes. Any hints? Thank...

Included Gem, version 1.3.5. Never installed any gems before; never did any special config for this Ruby. Ruby itself works, as does irb, and "gem" operates but can'...
All, I was wondering if anyone knew a better patten than: array_of_hashes.map { |hash_from_array| hash_from_array[:key] } for retrieving an array of values with a specific key from an array of hashes containing that key. ...

Looking at other people's code it seems really common to include an extra space inside curly brace blocks. Is there a reason for that? To me it seems to add extra keystrokes for added ugliness. Especially when things get nested: lambda { (1..5).map { |i| { :a => { :b => i } } } } For some reason it just looks more concise and coherent...

I have a small web-server that I wrote with Sinatra. I want to be able to log messages to a log file. I've read through http://www.sinatrarb.com/api/index.html and www.sinatrarb.com/intro.html, and I see that Rack has something called Rack::CommonLogger, but I can't find any examples of how it can be accessed and used to log messages. ...

I've been running this code on a linux box for a while now with no problems. Running it on my Mac this morning yielded a symbol table overflow runtime...
