I’m constantly passing a list of git aliases I use in my terminals. Here they are:
alias gb='git branch'
alias gba='git branch -a'
alias gc='git commit -v'
alias gca='git commit -v -a'
alias gd='git diff | mate'
alias gl='git pull origin master'
alias gp='git push origin master'
alias gst='git status'
There are a number of instances where you may find yourself with two arrays and you need to find the values that do not exist in both. This is fairly simple:
For these two arrays:
a = ["rockets", "saucers", "underwater", "warp"]
b = ["saucers", "fuel", "moon", "warp"]
A simple way to do this is to put the two arrays together and then remove the items that exist in both:
(a | b) - (a & b)
Gives you:
["rockets", "underwater", "fuel", "moon"]
sudo aptitude install -y imagemagick
sudo aptitude install -y libmagick9-dev
sudo gem install rmagick
Rails 2.3 is finally done and out the door. This is one of the most substantial upgrades to Rails in a very long time. A brief rundown of the top hitters:
Templates: Allows your new skeleton Rails application to be built your way with your default stack of gems, configs, and more.
Engines: Share reusable application pieces complete with routes that Just Work, models, view paths, and the works.
Rack: Rails now runs on Rack which gives you access to all the middleware goodness.
Metal: Write super fast pieces of optimized logic that routes around Action Controller.
Nested forms: Deal with complex forms so much easier.
And that’s just the tip of the iceberg. We’ve put together a complete guide for the Rails 2.3 release notes with much more information. Be sure to checkout the section on what was deprecated when you’re ready to upgrade your application.
You install 2.3 with (the final version is marked 2.3.2):
gem install rails
If you’re running on Passenger, be sure to upgrade to 2.1.2 as well. Rails 2.3 doesn’t run on older versions of Passenger!
We hope you’ll love it.
Thanks for the tip from @al3x on the XThemes tool. I love the midnight theme in textmate and now my eyes are happy in XCode.
We’re busy testing our apps on rails 2.2 now that it’s out.
Things are going very well. We’re here to help you with yours if you need us, send an email to support@imapenguin.com
Mongrel has served us well for the past year or so, but the simplicity of deployment in passenger along with the ever reliable apache has lured us into extensive testing. We’re getting slightly better performance numbers from passenger over mongrel with about 2/3 of the memory footprint. Please let us know at support@imapenguin.com if you see any wonkyness with any of our services. As we migrate over night.
So we all use some pasting service, but check out Gist, from Github. Each paste gets it’s own git repository. I’ve been using it all morning and love it.
Some cool features:
Bleh, there are some nasty ruby vulnerabilities out in the wild right now. Details are here. We’ll post an update as Linux distributions get patches to let you know who needs to take action to get fixes.
We’re compiling ruby from source for the time being on production machines until updates appear.

There is a bug in the capistrano git bridge that’s not been patched in the stable version yet.
If you’re getting:
fatal: Could not parse object
A quick and dirty hack is to add a task that just removes your git cache for now on the deployed server with:
desc "Clear that git cache"
task :clear_git_cache do
run "rm -Rf /#{deploy_base}/#{application}/shared/cached-copy"
end
before "deploy", "clear_git_cache"
It takes about 1 second longer to do the checkout but I don’t really notice.
