Software

I maintain a Web server using Apache 2, PHP, Perl, MySQL, and OpenSSL; an IMAP server running the up-and-coming RoundCube Webmail client; and a server for streaming MP3s. GNU Emacs, OpenSSH, TightVNC, and netstat are just a few of the tools I use to maintain my servers.

GNU Emacs

GNU Emacs is my editor of choice. Yes, I know a lot of people swear by Vim, which is more universally available, but Vim's shortcuts are just too unnatural to use with the Dvorak keyboard layout, which I prefer.

Being able to jump through a text file by character, word, sentence, paragraph, and page with just a few keystrokes saves a lot of time when editing long configuration files. I use Vim when I have no choice, but I feel much more at home in Emacs.

OpenSSH

I also use the OpenSSH suite extensively, almost always used in conjunction with GNU Screen. With OpenSSH I can do almost everything remotely that I could do at the physical terminal itself. I make sure I never send passwords over the Internet unencrypted, so I sleep better at night knowing SSH is keeping my data secure.

TightVNC

Full Story.

    Better memory profiling on Linux After more than a year of work, I’m pleased to release another version of heaptrack, the Linux memory profiler! The new version 1.1.0 comes with some new features, significant performance improvements and – most importantly – much improved stability and correctness.

  • Ten Years of Vim
     

    The philosophy behind Vim takes a while to sink in: While other editors focus on writing as the central part of working with text, Vim thinks it's editing.

     

    You see, most of the time I don't spend writing new text; instead, I edit existing text.
