JavaScript performance is one of the most important things in recent browser development.
Google did an awesome job with Chrome’s V8, and Mozilla’s Tracemonkey also raises the bar.
I usually compare the performance on this site
The tests were done on a MacBook Pro (2007), here the results.
My version control journey started with CVS, after that I looked at SVN, but
never really used it. The shortcomings of centralized repositories were too
obvious and with my increasing interest in Haskell I jumped on the distributed
version control train with
Darcs. I really, really
liked it, but it had some nasty things too. After a while I was looking for
something different and stumbled over
Mercurial, again I was
really happy with it but somehow my journey wasn’t over yet.
I sometimes forget to push or pull changes to or from a remote repository. To remedy the problem I wrote myself a little script to show me the status on the prompt.
It’s been a while since I wrote my Vim Introduction and Tutorial (exactly one year). A lot happened between now and then, I chose to get a better feeling about Emacs for example.
The reasons aren’t easily explained; The most prominent reason is the awesome AucTex-mode since I’m working heavily with LaTeX lately.
Anyways, learning Vim and Emacs is better than learning only one of them :-).
In this post I’ll go through some of the most prominent math programs available with source code.
This is by no means “original” work, I just collected the headlines and links to various mathematical software projects out there. This started with an offer of my University (Mathematica for 13 Euro), but I don’t want to invest time in a tool I won’t have (free, or almost free) access to for the rest of my life.
My article about using rsync to mimic the behavior of Apple’s Time Machine generated a lot of traffic, and more important, a lot of feedback.
In this article I’ll summarize and try to clarify a few things.
rsync is one of the tools that have gradually infiltrated my day to day tool-box (aside Vim and Zsh).
Using rsync it’s very easy to mimic Mac OS X new feature called Time Machine. In this article I’ll show how to do it, but there is still a nice GUI missing – for those who like it shiny.
Installing Mac OS X on a Mac is a breeze, yet I usually do two things after the installation to improve stability.
About one year ago I bought a second generation MacBook Pro. At first everything was fine and I didn’t encounter any weird sounds or screen flickers known from previous models. Unfortunately after a few weeks, it started to make some weird sound sometimes when I open it (or switch it on).
Here my journey to get rid of the problem.
While reading “The Definitive ANTLR Reference” by Terence Parr I encountered this quote. I’m a bit sceptic about XML beyond its use of data exchange, so the quote has completely won me over for the book.
Don’t be afraid to build a human-readable configuration file (I implore everyone to please stop using XML as a human interface!) or to build domain-specific languages to make yourself more efficient. Designing new languages and building translators for existing languages, when appropriate, is the hallmark of a sophisticated developer. —Terence Parr, The Definitive ANTLR Reference, Page 23.

Being an expert in XML is like being an expert in comma-separated values. —Terence Parr
