GoGaRuCo 2010 - San Francisco Ruby Conference

Had an awesome time here for two days, listening to talks, hacking on some code, learning, networking, even managed to sign up for the UCSF gym and to take a swim. Very nice organization, excellent venue, and fantastic talks. Definitely coming back next year. For the price it's well worth it. Here are some highlights:
  • Super useful resource for lookup up shell commands: http://shellhaters.heroku.com/posix
  • Terminator plugin: start your dev environment as you like it. Gem install terminator
  • http://github.com/rdy/fixture_builder Factory to Fixtures converter to speed up your tests.
  • pprof profile Ruby interpreter. Rack-Profiler project, great profiling tool.
  • Coffee Script - wrapper (ruby-esque) for javascript; rails 3.1 supports coffee script templates
  • Machine Learning - great talk, and O'Reiley book, http://twitter.com/igrigorik
  • minitest fastest testing framework, many mentions, very fast, supports RSpec and Test::Unit syntax
  • Caching: using fresh_when(:last_modified => ...) to enable proper HTTP caching in Rails 3.1
  • Arel: enables fragment caching that does not run SQL if the fragment is cached
  • ruby 1.9: require 'objspace' allows inspection of object counts and memory usage in VM

Car or Auto Make-Model-Year Database : For Breakfast

Make Model What?If you like me were tasked with loading a database of recent car makes/models/years, you would start by looking on the web and seeing if someone else just has it out there, readily available, hopefully for free, but perhaps for a tiny nominal fee.?If only it was that simple... I looked and looked, and couldn't find anything that would fit the above requirements. So I thought, who would know about US car models better than Kelly Blue Book? So I went on their site, and sure enough they have a javascript file that lists all known to them makes and models of used cars. Since the file is public, I figured it's not really "evil" if I scrape and parse it for my own benefit. Disagree? Have a better source? Then leave a comment.Anyway, to cut the long story short, I'm hoping to save a day or so to someone else who may, like me, be looking for this information. The ruby module shown below retrieves and parses the javascript from KBB site into a Ruby da…

Mac OS-X tips: How to run SSHD on an alternative port

This tip falls into one of those "I had to spend more than 10 minutes looking for an answer" category, so it's a worthwhile subject for a quick blog post. Why Run SSH? Running SSH on Mac OS-X allows you to login to your machine remotely, and also copy file securely via SCP command to and from your Mac OS-X host. But I am behind my own $50 router/firewall. Can I still connect to my computer from outiside?Yes. Most off the shelf routers and firewalls will allow you to do two things that are needed for this: Assign a permanent IP address to your Mac on a local network (see your router documentation for more details) Create a port forwarding rule on your router. Eg - any request to port 22 on your external IP (provided by your router) can be routed to the specific IP address of your Mac. Exact specifics on this configuration are once again available in your router documentation. Most off the shelf routers support this, including basic Netgear and D-Link. So let'…

Why I Like PostgreSQL

Today I gave a short presentation at work about PostgreSQL, and why I much prefer it to MySQL.

PostgreSQL vs MySQL: Eternal Battle
I may be misreading this, but it seems that there is a recent trend within startups to move away from MySQL, probably thanks to folks like Heroku on one side (who use PostgreSQL to the extreme, and help and contribute to it's development), vs folks like Oracle on the other side, tainting the "open source pureness" of MySQL :)

At my work we currently use a mid-sized MySQL 5.1 Percona instance, which is holding up quite well I must admit. Both PostgreSQL and MySQL have definitely converged to cover most features that people want, but my leaning is still towards PostgreSQL. I just agree with it's focus on data integrity, recovery, constraints, extensibility, while some of the early decisions in MySQL's design do not agree with me at all (like truncating long strings, 1/0 instead of booleans, ambiguous group by, etc). I think that data …
