Setting up Jekyll on Windows 7

2012-02-23T00:00:00-08:00

How I installed Jekyll on Windows 7

Step 1: Install Ruby with the RubyInstaller

Download and install Ruby (I chose rubyinstaller-1.9.3-p125.exe). Then download and unzip the DevKit version of Ruby from the same page.

How to install the DevKit

While installation is (in general) simple, please ensure you carefully follow each step below.

1. Preparation

If you previously installed the legacy DevKit devkit-3.4.5r3-20091110.7z, its artifacts were extracted into each Ruby installation and need to be manually removed. Remove the gcc.bat, make.bat, and sh.bat stub batch files in <RUBY_INSTALL_DIR>\bin and the <RUBY_INSTALL_DIR>\devkit subdirectory for each Ruby installation using the legacy DevKit. If you previously installed one of the legacy self-extracting DevKit’s, follow the SFX DevKit upgrade instructions.

2. Download Files

The current DevKit is available at the RubyInstaller download page with older versions available at the archives page. As backup, check our GitHub downloads page.

3. Extract Files

Left double-click the self-extracting executable (SFX) downloaded from Step 2 and choose a directory (without spaces) to install the DevKit artifacts into. For example, C:\DevKit. NOTE: the SFX is really a 7-Zip archive with a bit of embedded magic. If you already have 7-Zip installed, you can simply right-click it and extract it’s contents as you would a normal 7z archive. In the instructions that follow, the directory that you selected is identified as <DEVKIT_INSTALL_DIR>.

4. Run Installation Scripts

cd <DEVKIT_INSTALL_DIR> from Step 3 above. ruby dk.rb init to generate the config.yml file to be used later in this Step. Your installed Rubies will be listed there (only those installed by a RubyInstaller package are detected at present). edit the generated config.yml file to include installed Rubies not automagically discovered or remove Rubies you do not want to use the DevKit with.

optional ruby dk.rb review to review the list of Rubies to be enhanced to use the DevKit and verify the changes you made to it are correct. finally, ruby dk.rb install to DevKit enhance your installed Rubies. This step installs (or updates) an operating_system.rb file into the relevant directory needed to implement a RubyGems pre_install hook and a devkit.rb helper library file into <RUBY_INSTALL_DIR>\lib\ruby\site_ruby. NOTE: you may need to use the --force option to update (with backup of the originals) the above mentioned files as discussed at the SFX DevKit upgrade FAQ entry.

5. Test Installation

Confirm your Ruby environment is correctly using the DevKit by running gem install rdiscount –platform=ruby. RDiscount should install correctly and you should see Temporarily enhancing PATH to include DevKit… in the screen messages.

Next run ruby -rubygems -e "require 'rdiscount'; puts RDiscount.new('**Hello RubyInstaller**').to_html" to confirm that the rdiscount gem is working.

Installing Jekyll

Install Jekyll using gem install jekyll in your command prompt.

Clone Jekyll Bootstrap!

Go to the Jekyll Bootstrap website and follow the instructions there, then you’re done!

Music genres I had never even heard of

2012-02-23T00:00:00-08:00

Wikipedia, I Love You

Today while procrastinating from my calculus studies, I found this short list of electronic music genres.

A list of all the music genres I had always dreamed of. Now I have it, and now I have a lot of new material to consume! Yay!

Thank you Wikipedia, this is why I donated 100 SEK to you last year. I will most likely do it again, just for the sake of this list.

Learning from Ludum Dare

2011-08-22T00:00:00-07:00

You have probably not heard about the indie game developer competition called Ludum Dare. It's a rapid game creation community where you compete against each other to complete a game within 48 hours and then rate the games produced during the weekend. After two weeks a winner will be named based on who got the most votes.

The difference, on the 21st occurrence of Ludum Dare, was that the creator of MineCraft, @notch (Markus Persson), decided to join the tournament as he's done a few times before. Enter Publicity.

Here is a timelapse of @notch programming Metagun for a previous competition:

A list of games by @notch for Ludum Dare:

The source code for these games are available on the website, such is the requirement of Ludum Dare - and there is much to learn from each one of them!
