GIT SHOULDN'T BE SO HARD TO LEARN.

When you're just getting started, something as straightforward as a merge can be terrifying. It can take a long time to really become comfortable using some of Git's more advanced features. (It took me a year or two.)

Once people achieve some level of Git enlightenment, they tend to make statements of the form 'Git gets a lot easier once you realize X' -- but that doesn't do much for people staring up Git's steep learning curve.

My goal with this site is to help you, Dear Reader, understand what those smug bastards are talking about.

gifme is a simple command line tool to generate animated GIFs.

lsof is the Linux/Unix über-tool. I use it most for getting network connection related information from a system, but that's just the beginning for this amazing and little-known application. The tool is aptly called lsof because it "lists open files". And remember, in Unix just about everything (including a network socket) is a file.

Private Eye is a free network monitor for Mac OS X Lion. When an app makes a network connection, you see it instantly on your screen. There's no delay and you don't have to use a separate recording mode.

"So one day Jeff Bezos issued a mandate. He's doing that all the time, of course, and people scramble like ants being pounded with a rubber mallet whenever it happens. But on one occasion -- back around 2002 I think, plus or minus a year -- he issued a mandate that was so out there, so huge and eye-bulgingly ponderous, that it made all of his other mandates look like unsolicited peer bonuses."

In this course, you'll learn about some of the most widely used and successful machine learning techniques. You'll have the opportunity to implement these algorithms yourself, and gain practice with them. You will also learn some of practical hands-on tricks and techniques (rarely discussed in textbooks) that help get learning algorithms to work well. This is an "applied" machine learning class, and we emphasize the intuitions and know-how needed to get learning algorithms to work in practice, rather than the mathematical derivations.

This class will introduce you to the Web technologies and give you experience creating Web applications. In the process you will learn about markup languages, scripting languages, network protocols, interactive graphics, event-driven programming, and databases, and see how they all work together to deliver exciting applications.

Product design is easily the hardest aspect of building software today. Technology, hiring, funding, aesthetic design, and press are all minuscule in comparison. When I talk about product design I’m referring to the process by which you decide what your product does and does not do.

This is — by far — my favorite aspect of working at GitHub. Everything is asynchronous.

Inspired by Crafting Rails Applications, ModestModel provides an ActiveModel-compliant class that allows you to quickly create simple, table-less models. The intended use is to back interactions with external APIs with Ruby-friendly models rather than raw structured data (such as hashes).

Here’s how I set up an OS X 10.7 (Lion) thoughtbot laptop in 2011.

These are the steps I took to set up the RailsCasts site on a Linode with Ubuntu 10.04 LTS installed.

By default Heroku serves everything in public directly via nginx. This is a problem for us since we don’t get a chance to configure the caching headers. Instead, use the Rack::StaticCache middleware (provided in the rack-contrib gem) to serve static files, which by default adds far future max age cache control headers.

This time around I wanted to focus on how to setup PostgreSQL on a dedicated server instance. In addition, I will cover how to tweak the configuration settings as a first-pass towards optimizing database performance and explain which parameters are the most important.
