This sounds promising:

The best part from the Rails side, is that you don’t have to change anything at all in your code to swap a varchar out for an ENUM.

To have your text input field pre-filled in with some text that disappears as soon as the user selects it, use the attribute placeholder:

<input type="text" placeholder="User name here">

This will only work in recent browsers (IE >= 10, FF >= 4, Chrome >= 4, Safari >= 5, Opera >= 11.6).

New way to install an actual puppet version on ubuntu

ActiveSupport >= 3 has

Date.parse('2011-02-10').beginning_of_quarter #=> 2011-01-01
Date.parse('2011-02-10').end_of_quarter #=> 2011-03-31

You can manually calculate the quarter index like

(Date.parse('2011-02-10').month / 3.0).ceil #=> 1

Yes, you do actually divide by 3.0, not 4.0.

MySQL has

SELECT QUARTER('2011-02-10'); #=> 1

Generated animations are free to use without backlink obligations...

On case-insensitive file systems like Mac's HFS+ (per default – you may change this, but it won't work for all programs), git won't recognize when you change the casing of files in your repository.

Workaround

git mv -f oldfile.name Oldfile.name

If you upgrade to the mysql2 gem, you will run into the problem that the server's database.yml (which is usually not under version control) needs to change exactly on deploy.

You can however make your database.yml work for mysql and mysql2 at the same time. Simpy do this

production:
   adapter: <%= defined?(Mysql2) ? 'mysql2' : 'mysql' %>

Last week saw a security issue with rails 2.3 that required a fix. While an official patch was provided, the 2.3 branch is no longer maintained. So we forked it.

(I'm sure there are already 100 other forks doing absolutely the same, but they are not very easily discoverable.)

To use our fork, change the gem "rails"... line in your Gemfile to this:

gem 'rails', :git => 'https://github.com/makandra/rails.git', :branch => '2-3-fixes'

The intent is to make as few changes to the f...

Upgrade seems to work fine. If you installed your old skype from a Ubuntu repository, you need to remove it first using:
sudo apt-get remove skype
Then simply install the .deb from the official page. You won't lose any settings.

Introspect the Ruby Heap by indexing, counting, locating references to and detaching (in order to release) objects.

If you have a file that looks like a precompilation fingerprint, the Rails asset pipeline will not see it. So don't have filenames like this:

• The amount helper now retrieves the decimal separator from your I18n dictionary (number.format.separator) instead of hardcoding it to a comma.
• money_amount helper tunnels options to amount

This script loads a dump into your development database.

You can provide the full path to you database dump like this:

load-dump path/to/my.dump

When you call load-dump without any arguments it will show a menu with all dumps in your ~/dumps/ folder.

This script is part of our geordi gem on github.

Myth #5 (Each HTTPS Site Needs its Own Public IP Address) is actually still true, but the rest of the article is worth reading.

xip.io is a magic domain name that provides wildcard DNS for any IP address. Say your LAN IP address is 10.0.0.1. Using xip.io,

          10.0.0.1.xip.io   resolves to   10.0.0.1
      www.10.0.0.1.xip.io   resolves to   10.0.0.1
   mysite.10.0.0.1.xip.io   resolves to   10.0.0.1
  foo.bar.10.0.0.1.xip.io   resolves to   10.0.0.1
  

...and so on. You can use these domains to access virtual hosts on your development web server from devices on your local network, like iPads, iPhones, and other computers.

deploy-to-production now calls Capistrano with bundle exec since we started to bundle Capistrano in all projects.

The following code activates autoloading using ActiveSupport 3.x:

require 'active_support'
require 'active_support/dependencies'
relative_load_paths = %w[app/controllers app/models]
ActiveSupport::Dependencies.autoload_paths += relative_load_paths

You can search for large messages by folder or by your entire email account.

Some progress was made by browsers on implementing CSS filters like blur, greyscale or some other effects. You might already know the legacy CSS filter attribute that old IE versions used to perform DirectX transformations. Luckily these legacy filters are removed in IE10. The good news is, newest WebKit-based browsers like Chrome (18.0+) Safari and Mozilla Firefox expe...
