munin-node-configure rules

It occurred to me that I should be able to do whatever ubuntu does to automatically choose the right plugins when setting up munin-node. So I went looking and found munin-node-configure in all it's glory. Re-purposing a server image for mysql just a little bit easier:

Previous versions are here and here (thanks cperciva). The standout change is the rise of Slicehost.
This time around the script pulled domains straight from YC's FAQ.

Better wildcarded subdomains for testing locally on OS X

Locally testing apps that let users create their own subdomains can be a pain. As much as I wish it were as easy as putting "*" in /etc/hosts as a wildcard, it has to be more complicated. For a long time I had a DNS server running locally that resolved everything under .dev to 127.0.0.1, but when I replaced my hard drive recently I went shopping for a better solution. I found one, proxy auto config files.

With a little help from stack overflow I came up with the following to make anything that ends in .dev route to localhost:

function FindProxyForURL(url, host) {
  if (shExpMatch(host,"*.dev")) {
    var port = url.match(/^\w{3,5}:\/\/[^:\/]*(:(\d+))?/)[2];
    var proxy = "PROXY localhost";
    if(port){proxy += ":" + port;}
    return proxy;
  }
  return "DIRECT";
}

Put the above in a file somewhere (I named mine ~/.proxy.pac) then to add it go to Network in System Prefences and add it to Proxies in advanced mode:


This will work for Safari. You can add it again in the Firefox proxies setting, but even better is to just install the System Proxy extension that will make Firefox use the system wide proxy settings. For IE testing in VMWare I just replaced "localhost" in the var proxy = "PROXY localhost"; line with the IP of my mac that VMWare shares with the IE VM. IE also seemed to deal better with a pac file accessible via an HTTP URL instead of a file path so I hosted the IE pac file on my local webserver.

RSpec has profiling built in. Awesome.

Zsh Capistrano Task Completion on OS X

The Zsh task completion I found for Capistrano was a bit out of date.

The following is working for me:

_cap_does_task_list_need_generating () {
  if [ ! -f .cap_tasks ]; then 
    return 0;
  else
    accurate=$(stat -f%m .cap_tasks)
    changed=$(stat -f%m config/deploy.rb)
    return $(expr $accurate '>=' $changed)
  fi
}

_cap () {
  if [ -f config/deploy.rb ]; then
    if _cap_does_task_list_need_generating; then
      echo "\nGenerating .cap_tasks..." > /dev/stderr
      cap -vT | awk 'FB != 1 {if ($0 ~ /^$/){FB=1}else{print $2}}' > .cap_tasks
    fi
    compadd `cat .cap_tasks`
  fi
}

compdef _cap cap

Based on rake task completion.
Put it somewhere like ~/.zsh/cap_completion and add the following to ~/.zshrc or ~/.zprofile

 # enable completion if you haven't already
autoload -U compinit
compinit
 
# load capistrano completion
source ~/.zsh/cap_completion
