Gate One

I came across a program called Gate One by LiftOff Software that just amazed me. This is an open-source, web-based ssh terminal. It is capable of multiple users, sessions, and bookmarks. I’ve tried a number of AJAX terminals or Java applet based ones in the past. The javascript ones usually did not have very good terminal emulation, while the Java apps worked, but worked just like a local desktop app (making it’s own connection to port 22). Gate One uses WebSockets, allowing for full duplex communication through your web browser over the same port 80 or 443 used to serve up the web page. Read the rest of this entry »

awk Tutorial

La commande awk

Philosophie

On parle souvent de awk comme d’une version améliorée de sed. En effet, on retrouve la notion de portée de commande et de manipulation de texte, mais à mon avis, cette comparaison s’arrête la. Si sed dispose d’une commande if, l’on ne peut parler de langage de programmation alors que cette notion s’applique totalement à awk. Il n’est pas question ici de traiter totalement awk mais juste de vous donner un bref aperçu de sa puissance.

Dû à la complexité de awk, il ne nous sera pas possible de traiter ce langage de façon extensive. Aussi, nous allons procéder à un rapide tutorial dans la première partie et donner une référence rapide des fonctionnalités les plus utilisées dans une seconde. Read the rest of this entry »

NTFS Cloning and shrinking

“Honey, I shrunk the filesystem!”

Recently I bought a solid-state harddisk, an Intel X25M. I wanted to use this disk in my Windows development system, without having to do a fresh install of Windows XP. I really didn’t want to install all my applications again, not to speak of all the custom configurations and tweaks I usually apply to Windows to make it palatable. So I thought I’d just make a image copy of my old harddisk to this new one, and be done with it.

sed – Stream EDitor – works as a filter processing input line by line.
Sed reads one line at a time, chops off the terminating newline, puts what is left into the pattern space (buffer) where the sed script can process it (often using regular expressions), then if there anything to print – sed appends a newline and prints out the result (usually to stdout).
