It seems that a shell history meme is passing around the blogosphere. I first saw it on Dan Mills' blog post via Planet Mozilla. There are already 10 Mozilla hackers posting their top used shell commands, so I thought I'd do it too.

koeji:~ kourge$ uname -a
Darwin koeji.local 9.2.2 Darwin Kernel Version 9.2.2: Tue Mar  4 21:17:34 PST 20

koeji:~ kourge$ history | awk '{a[$2]++} END {for(i in a){print a[i] " " i}}' | 
sort -rn | head
88 ls
81 cd
28 cvs
26 rm
26 md5sum
23 ./firefox-bin
22 sudo
12 ssh
12 js
9 less

A few notes:

• md5sum is actually md5 on Mac OS X. I aliased md5 so that I wouldn't suddenly have a hard time adapting should I start using a Linux system.
• js is an alias of java -Xms256m -Xmx512m org.mozilla.javascript.tools.shell.Main, which is the command to invoke the Rhino shell, which I sometimes use when I write shell scripts in JavaScript. Rhino is an awesome JavaScript implementation in Java.
• You can see from the cvs count that I'm slacking off recently when it comes to maintaining Drupal modules.

So, fellow Drupalers / Drupalites, what are your most commonly used terminal commands? Beware of the line break before sort -rn when pasting the command into your terminal.

Alex Russell has pointed out that Firefox 3 has some quirky issues with JavaScript arrays, namely, an array made from a literal has a different constructor than an array made from instantiating the global array object. Long story short, the below is true:

[].constructor != new Array().constructor

Update

It seems like this is a Firebug-specific issue. If you try to evaluate the above in Error Console, you'll get false.

If you don't read or watch Bleach, this post will seem like nonsense to you. Otherwise, read on.

After the Google Highly Open Participation (GHOP) contest ended, we've got a huge influx of new contributors in Drupal. The positive influence the GHOP brought was truly amazing. To keep the beat rolling, DROP was created. Standing for Drupal Really Open Participation, we continue the goodness of a task-based system and pancakes.

This is a really brilliant idea. It serves as an incentive for regular contributors. It interests new contributors. It gives recognition. These are all successful traits of GHOP that DROP wishes to carry on. I've personally already claimed one task and plan to work on more once I have the first one cleared.

So what can you do to help? Read on.

One of the changes in Firefox 3 Beta 3, which has just been released, brings the object destructuring shorthand to JavaScript 1.8. Why would you need object destructuring in the first place? Commonly when you need to pull certain values out of an object structure, as demonstrated here. The introduced shorthand sprinkles a bit more of syntactic sugar into object destructuring assignments. Read on for concrete examples.

With the release of Drupal 6 around the horizon, I made a presentation (as part of GHOP) that (attractively) outlines 5 new features in Drupal 6 that I deemed "awesome".

The following features are outlined:

1. OpenID support
2. Module update status
3. Improved usability
4. Alias filtering
5. Internationalization

Get the presentation.

About two and a half weeks ago I wrote about jQuery being underutilized. That's nothing compared to Spellify, the absolutely perfect and horrendous example of how grossly unutilized Prototype is. Read on.
