Curious Code for Curious Coders

Redir Is Awesome

More than anything, I love tiny tools that do one thing, and do it well. The UNIX philosophy sends me into fits of programmery giggliness for precisely this reason.

Recently I discovered a tiny new tool to add to my toolbox. I had a test server running on port 3014, and needed to briefly expose it on port 80 (I know, I know, I’ve just made myself eligible for a righteous noodle-lashing).

Hey, New Blog Software Again!

So after many years of hating the blogging software I implemented to replace the blogging software I hated before, I’m implementing new software to replace the replacement software. Which I hate.

Updates to follow.

Hidden Chrome Features on CR-48

After having playing around with ChromeOS on the CR-48 netbook (which I’ve blogged about before), I’ve found a few more interesting tidbits that let you dig deeper into the system.




tl;dr

  • Experimental Features/Flash Drives: chrome://flags
  • Nicer View of Memory Usage: about:memory
  • Hilarious Pranks: about:crash
  • Wi-Fi Troubleshooting: about:network
  • Manage Extensions and Apps: chrome://extensions

Chrome OS on the CR-48: It Has Developer Bits!

So for anyone out there who is not already insanely jealous of my good looks and/or impeccable fashion sense, you should know I was one of the recipients of a CR-48 netbook in Google’s free giveaway.

A full review is forthcoming (sneak preview: it is awesome), but here I just wanted to share a couple quick things I found that turn ChromeOS from an interesting toy to a usable developer’s tool.

tl;dr

  • Process Manager/Task Manager: Shift-Esc
  • Shell/SSH Client: Ctrl-Alt-t
  • Developer Tools: Ctrl-Shift-i

Zombie Songs

For all those times when you’ve been thinking to yourself “Man, this would be the perfect situation in which to play a zombie song,” I’m glad to say modern independent musicians have stepped up to fill this gap:

Further zombie song recommendations are welcome in the comments.

A More Effective Name

A quick note:

If you are:

  • Using Rails
  • Using RSpec
  • Have just discovered the incredible joy of named scopes

…restrain yourself, by any means available (up to and including physical violence) from creating a named scope called “public” or “private.” The reasons for this should be fairly obvious.

Really, whoever ends up cleaning up behind you will appreciate it.

Annihilate Ubuntu’s Annoying System Beep

A quickie to remind myself next time I build an Ubuntu box, and am being slowly driven batty by a tiny, tinny obsolete PC speaker made of hate:

sudo gvim /etc/modprobe.d/blacklist

(or /etc/modprobe.d/blacklist.conf, for Ubuntu 9.04) …and add the following line:

blacklist pcspkr

From the command line, kill it in the current session:

sudo rmmod pcspkr

No more waking the baby with late-night hacking sessions!

Select Tag Funkiness With Merb

In my ongoing travails with Merb & Friends, I’ve run across a few behaviors with the select() form helper method. Since there’s currently a dearth of examples, I thought I’d document them for myself and future googlers.
