Hello developers, how are you? Fantastic. Does your code look like mine? No. Could it load like mine? Yes. Should you use rack-gist to load your gists? I don’t know… Do you like not blocking your users while you page loads another Javascript file? Do you want code that looks like it could write your app for you in the dream computer it built for you with its own DWORDS? Of course you do. Recursive Hasselhoff! Into the best gisting of your lif...

Find queries missing indexes in your Rails application
Rails developers aren’t exactly known for getting their indexes right (or even at all) on their databases. Granted, databases are a tough subject, and some people and companies make their living dealing with only databases, and some only with one database (like MySQL or Oracle). If you coming to web development with no formal background in databases, and it’s all new to you, then it’s totally understandable to maybe forget about indexes initia...

Getting rid of transactions for the poor man
A quick post for today. Want to get rid of transactions from ActiveRecord for something? Here’s a cheap way to do it. It only works for MySQL obviously, but you can roll your own if you are on postgres. I’ll make it a bit less crappy and make it a gem or something.
