Diving into OOC, a fun new programming language

OOC is cool. Yesterday I started writing some code in it after reading about it on the github blog. Here is the first result:

I’m extremely happy with how well this performs. Using the latest ooc Java compiler from the github trunk to handle the each() functions, this compiles down to a bunch of C code, and then is automagically compiled behind the scenes into an ELF Binary! This is totally awesome, and I have to commend nddrylliog and the other contributors for their work on this awesome project. Now I should use it for something useful :D

A quick note about getting it running on Ubuntu:


sudo apt-get install sun-java6-jdk
git clone git://github.com/nddrylliog/ooc.git
cd ooc
JAVA_HOME=/usr/lib/jvm/java-6-sun/ make

At least, that’s how I did it. Then I compile all my ooc with a Makefile like this:


INPUTS=$(wildcard *.ooc)
TARGETS=$(patsubst %.ooc, %, $(INPUTS))

all: $(TARGETS)

%: %.ooc
  java -jar ~/repos/ooc/bin/ooc.jar $@

That will compile all ooc files in the directory.

Ruby to generate RSS feeds for sites that don’t offer them

There’s this site that has an equipment exchange I wanted to keep track of. Yet, it’s done with what seems to be a custom php file rather than vbulletin, so none of the usual RSS feeds from the site apply to it. So, I decided to make a scraper/feed-generator to get me the latest version every 5 minutes and generate a nice RSS feed, so I can view it in Google Reader. The volume of posting is low enough that this won’t be annoying to see in my daily feeds.

I usually use Ruby for this because it offers Hpricot, a very nice and fast scraper and XPath interface. This time, I resolved to find something that does RSS generation better, and I stumbled upon RubyRSS, which happens to be in the core ruby distribution!

Here’s what I ended up with after about an hour:

Now this is impressive if you look at the fail of html id and class attributes coming out of the original page. I had to base everything off of the links to the items that were not images, and then the structure up the tree from there (see the liberal use of .parent). I’ve rediscovered that Hpricot is awesome (_why, come back to us!), and that it truly only takes 30 lines of code to generate a nice RSS feed in ruby. The resultant RSS feed for MDShooters Classifieds site is here.

And now, yet another RSS feed generator: MD Super Ads

Here’s the code:

GitHub Gist Plugin

Look how awesome this plugin is! Just typing [gist id="72075"] gets you:

More information here. I wanted to change the appearance a little, so I did this to my theme in WordPress:

I love that.
