Awesome color schemes for RubyMine, Sublime Text 2 and other editors.

To install the themes into your Rubymine, copy intellij-themes/*.xml from the repository to your local ~/.RubyMine40/config/colors. Then restart RubyMine.

Enjoy!

If you get a message like this:

Jan 21 13:42:38 foobar syslogd: /var/log/authlog : no such file or directory

But you are sure the file exists and it have the correct permissions:

# example for Solaris 9
-rw-r--r-- 1 root sys 8,0K 21. Jan 13:51 /var/log/authlog

Then you perhaps have a trailing whitespace after /var/log/authlog in the /etc/syslog.conf.

Note: Use TAB to separate log components from log file names in Solaris. Because spaces do not work.

If you worked with a system Ruby before switching to RVM, this system Ruby will be in your way when you switch between projects with/without RVM.

It's hard to get rid of your system Ruby entirely, but you can tell RVM to just use a given Ruby by default, e.g.:

rvm --default use 1.8.7

You need to re-open existing terminals for the changes to take effect.

Note that this will not actually remove the ruby package from your system, it just isn't used anymore.

Geordi now has a script that runs capistrano with all known deploy targets (i.e. staging, production...).

Use with

geordi capistrano deploy:migrations

or

geordi capistrano deploy

The abbrevation geordi cap ... works as well.

Apache HTTP server benchmarking tool (ab) is a nice tool to test performance on sites delivered by HTTP. If the site you're about to test is placed behind a login, follow these steps to successfully use ab on it.

1. Open the site to test in the browser of your choice. Do not login yet.
2. Use developer tools to show all cookies used by the site. (Chrome: Ctrl+Shift+i, open the 'Resources' tab and click on the site below 'Cookies' on the left. Firefox: Right-click on the site, open 'We...

So you want to find out how many horizontal pixels you have available on a mobile device. This is super difficult because:

• Modern mobile devices have high-density displays where 1px in your CSS e.g. corresponds to 2.25, 4, ... physical pixels on the screen hardware.
• Difficult APIs
• Inconsistent APIs
• Screen orientation can change when the user rotates h...

If you say git stash, your stashed changes will be identified with an automatically generated message:

$ git stash
Saved working directory and index state WIP on master: 77af0df Merge branch 'production'

While this is okay to temporarily stash away stuff, you may want a better identifier for your changes so you can find them more easily if you stash often.
Of course, there is a way to do it with git:

$ git stash save doing crazy things
Saved working directory and index state On master: doing crazy things

Note that you n...

If you use Tempfile and pass your own filename containing an extension, it will just be consumed by the Tempfile's filename:

>> Tempfile.new('foobar.xlsx').path
=> "/tmp/foobar.xlsx20130115-19153-4ykpwm-0"

If you want to keep the file extension, pass filename and extension as an array:

>> Tempfile.new([ 'foobar', '.xlsx' ]).path
=> "/tmp/foobar20130115-19153-1xhbncb-0.xlsx"

Use Socket.gethostname. So for a machine whose hostname is "happycat", it will look like this:

>> Socket.gethostname
=> "happycat"

That should work right away for your Rails application. For plain Ruby, you first need to do:

require 'socket'

If you don't want to use Socket for some reason, you can still just use the hostname command, at least on non-Windows machines. Keep in mind that you need to remove trailing white space from the result of the system call.

>> `hostname`
=> "happycat\n"
>> `hostname`.stri...

When calling a scope like current_power.user?(user), Consul will no longer trigger a query if the users power selects all records (SELECT * from users). This should make such checks much faster for users who can access many records, like admins.

You can now define multiple powers at once:

power :users, :updatable_users, :creatable_users do
  ...
end

The way MySQL's FULLTEXT tokenizer splits text into word tokens might not always be what you need. E.g. it splits a word at period characters.

Since the tokenizer has near-zero configuration options (minimum word length and stopwords list), you need to hack it. There are three options available.

Option 1: If you like pain

Write a Full-Text parser plugin in C.

Option 2: Make the problem go away

Upgrade the offending gem. If you cannot or don't want to upgrade, lock rake to 0.8.7.

You will get this when you are using the latest version of Rails with a recent version of Rack:

SECURITY WARNING: No secret option provided to Rack::Session::Cookie.
This poses a security threat. It is strongly recommended that you
provide a secret to prevent exploits that may be possible from crafted
cookies. This will not be supported in future versions of Rack, and
future versions will even invalidate your existing user cookies.

The warning is caused by Rails calling Rack incorrectly. [It is unclear](https://github.c...

I needed a way to make my apps full screen from bash scripts. There is no super-easy way, but it's not too hard either.

Put the attached script into e.g. /usr/local/bin and make it executable. Now you can call

fullscreen Safari

and Safari will go full screen.

Notes

• This script needs activated access for assisting devices. Turn it on with osascript -e 'tell application "System Events" to set UI elements enabled to true'.
• The capitalization of the application name is important, i.e. it's TextMate and not textmate.
• ...

Example input:

li.active a:link

Example output (specificity):

| 0 | 2 | 2 |

While you are probably using will_paginate to paginate ActiveRecord scopes, it can actually paginate plain Ruby arrays. The resulting arrayish object will have the same methods as a paginated scope, e.g. #total_entries. This means you can render pagination controls with the same code that works with paginated scopes.

To enable this, add an initializer config/initializers/array_paginate.rb:

require 'will_paginate/array'

You can now say:

> numbers = (1..1000).to_a
> page = numbers....

40 new icons, spinner-style rotation with CSS animations, smaller file size, possibility to sub-set the font to only include the icons you need.

Let’s take a look at what you need to do to get your app ready for Rails 4.

A cozy place to pick a short and catchy name for your product, company or domain.

With the impending release of Ruby on Rails 4, it looks like a lot of developers will be updating their web applications in the coming new year.

To help with this transition, over the next 31 days, we are going to be releasing a series of blog posts going over everything you will need to know about Rails 4 for an effortless upgrade.

Every time you call $(...) jQuery will create a new object. Because of this, comparing two jQuery collections with == will never return true, even when they are wrapping the same native DOM elements:

$('body') == $('body') // false

In order to test if two jQuery objects refer to the same native DOM elements, use is:

var $a = $('body');
var $b = $('body');
$a.is($b); // true

If you wear a lot of hats in a small team, or if you feel like your projects could be more successful if they looked better, this is for you. Here are five traditional elements and principles of art and design that will cure the ugly (or at least disguise it).
