"I was always amazed by the way emacs gurus navigated through source code. It almost seemed like magic. They see some function call, and then with some short keyboard combo jump to another file, on the exact place where the function was defined. The 'magic' in this case is a tag file..."

"The Pragmatic Programmers recommend learning a new programming language every year. I thought for a long time that this was a good idea, but didn't really act on it. Instead I'd dabble in a dozen languages a year. While this has built my intuition as to what various languages are like it has not made me a competent programmer in a new language.

"Functional Programming is old. Ancient. Like right after FORTRAN. But it’s the future. Trust me, I’m named after the dude who knew about Jesus 700 years early. Seriously, it’s not going to take 700 years for FP to go mainstream. Some would argue that it already is. Python, Ruby, and others have adopted a number of FP features.

"Many programs have start-up settings, which they read from a configuration file or from some database. Emacs is no exception: when it starts, it reads a file called ".emacs" from your home directory. However, the big difference is that .emacs does not consists of simple "key=value"-pairs. Instead, your .emacs is an Emacs-Lisp (elisp) program itself.

«For a long time, I've had a hack in my local elisp directory that let me easily visit related files in my perl projects [...] Now that I've started programming more frequently in other languages, I've missed having this feature. Instead of hacking something together for every other language I might use, I decided to generalize the concept of a "project" and "related files".

"EMACS(1) is a real-time display editor which can be extended by the user while it is running. Extensibility means that the user can add new editing commands or change old ones to fit his editing needs, while he is editing. EMACS is written in a modular fashion, composed of many separate and independent functions.

"A while ago I've blogged about my switch from Vim to Emacs, promising a blog post series, quite a mouthful :-) nevertheless, it's time to continue the series. The first part was about why I think that nowadays Emacs is ready to be switching to. This second part is about flawed Vim design choices which substantially contributed to my choice..."

"I use Emacs for all text editing, except for LaTeX which I use Texmaker for due to the quick start wizard, and quick build functions. Yesterday, I decided to try to implement these functions in elisp, Emac’s dialect of Lisp..."
