If my latest post on the topic did not tip you off, I am a Vim fan. So before some of you start stoning me, let me present you a list of "obscure Vim commands." What I mean by that is: a collection of commands that you might have not encountered before, but that might be useful to you. As a second disclaimer, I do not know which commands you might know and which one you find useful. So this list really is a collection of relatively less known Vim commands, but which can still probably be useful.

Tmux (short for "Terminal Multiplexer") lets us launch multiple terminals in a flexible layout on a single screen, so that we can work with them side by side. For example, on one pane we can edit some config files with Vim, while on the other we are using irssi to chat and on other pane, tailing some logs. Then open another window to update your system, and another to SSH to some servers. Navigating through them is just as easy as creating all these windows and panes. It is perfectly configurable and customizable so it can become an extension of your mind.

GTD—or “Getting things done”—is a framework for organizing and tracking your tasks and projects. Its aim is a bit higher than just “getting things done”, though. (It should have been called “Getting things done in a much better way than just letting things happen, which often turns out not to be very cool at all”.) Its aim is to make you have 100% trust in a system for collecting tasks, ideas, and projects—both vague things like “invent greatest thing ever” and concrete things like “call Ada 25 August to discuss cheesecake recipe”. Everything!

Sound like all other run-of-the-mill to-do list systems, you say? Well in many ways it is, but there is more to it, and it’s really simple. Promise! So please read on.

Hydrogen is a very nice QT drum sequencer and synthesizer in one. We get a lot of questions about the best way to use Hydrogen in conjunction with Rosegarden, and I thought it would make for a nice topic here in this new series of tutorials.
