Basic tools you want to know

We are managing our code versions with Git. It's like Subversion, Perforce and other VCS you may have worked with, but with a P2P twist. Although we work with a central server (github, gitlab and the like), it is just one of many types of workflows used in the industry, so here are some of the major points you need to know:

Some Git Basics, Also see GitHub's Learning Lab.

Let's start with the basics of how X Window System works. X uses client-server model. An X server program runs on a computer with a graphical display and communicates with various client programs (X clients). The X server acts as a go-between for the user and the client programs, accepting requests for graphical output from the client programs and displaying them to the user (display), and receiving user input (keyboard, mouse) and transmitting it to the client programs.

In X, the server runs on the user's computer, while the clients may run on remote machines. This terminology reverses the common notion of client–server systems, where the client normally runs on the user's local computer and the server runs on the remote computer.

The One Secret Trick To Becoming A Genius Programmer

Okay, the title of this post is a bit of a lie. There's no one secret trick to becoming a genius programmer - there are two, and they're more habits than tricks. Nevertheless, these kind of 'secret tricks' seem to resonate with people, so I went for this title anyway.

Every once in a while, a somewhat strange thing happens to me. I'll be helping somebody out on IRC - usually a beginner - answering a number of their questions in rapid succession, about a variety of topics. Then after a while, they call me a "genius" for being able to answer everything they're asking; either directly, or while talking about me to somebody else.

Now, I don't really agree with this "genius" characterization, and it can make me feel a bit awkward, but it shows that a lot of developers have a somewhat idealistic and nebulous notion of the "genius programmer" - the programmer that knows everything, who can do everything, who's never stumped by a problem, and of which ther
