Firefox Extensions
Jan 10th
Thought this might double up as a note of the firefox extensions I currently have installed — I’ve tried getting this to script, but, the source file isn’t something I’m over-familiar with, and getting fields to match-up ain’t happening, due to my crapness.
Anyhow, I would appear to have these firefox extensions installed:
- Adblock Plus
- AutoPager
- BetterFlickr
- Better YouTube
- Delicious Bookmarks
- DownloadHelper
- Echofon
- Extended Statusbar
- Fast Video Downloader (with SearchMenu)
- Firebug
- Firefox (default)
- Firefox (en-GB)
- Flagfox
- Flashblock
- Gmail Manager
- Greasefire
- Greasemonkey
- Image Download
- Image Zoom
- Inline Code Finder for Firebug
- is.gd Creator
- JavaScript Options
- keyconfig
- Magic’s Video Downloader
- oldbar
- Password Exporter
- Save Image in Folder [sic]
- ShowIP
- SkipScreen
- TinyUrl Creator
- Ubuntu Firefox Modificiations
- URL Fixer
- VMware Remote Console Plug-In
- Xulrunner (en-GB)
- YesScript
A few of those don’t have links I can identify from the URI.
Want some code that vaguely does this for you?

Conditional Prompt colo(u)rs
Dec 23rd
I often work on several different machines, for different projects and things. It’s bloody annoying when I get the wrong machine!
I thought. I know what, I’ll make all of these machines use a colored prompt, and make that lot of machines use a different one.
(At this point, I should say that my dotfiles, and a variety of other things are kept in a subversion repo. Most of those bits are my-eyes-only (particularly a lot of the very badly/hastily thrown together scripts), but a few bits I’m gradually releasing.)
After mentioning this on twitter, a couple of people have been interested in how I did it.
The solution is quite easy, work out the hostname, and from that determine the ‘class’ of machine, and then apply some colors. The archwiki was useful in getting out the colors to use; along with underlining, and emboldening (I never use underlining, except in manuscript: ghastly thing that obscures text).
Whilst not perfect (the color parts could be set as a variable, and then passed to the PS1 line; I could have used “else” clauses…), it works. For me, so, erm, here’s my .bashrc — you want from the # work out machine name/domain: line.
A simple switch wotsits in screen(1), and
$ cd ~/pseudohome && svn up
followed with a
$ . .bashrc
is how I deploy (some people have an ’svn up’ in their start-up scripts, I don’t).
Comments here, if you want to.
Dell Order Checking: via cron
Jul 31st
Ok. So let’s start off with a fairly obvious statement. I’m indolent. And I can write scripts. This is a dangerous, nay, perilous pairing…
So, with this existing laptop really getting on my nerves, and the lack of email coming from Dell regarding the new ‘un I ordered, I thought I’d tidy up some diff-scripts used $ELSEWHERE, and re-appropriate for quick-and-dirty order-tracking.
Fairly simple: fetch a web-page, in this case the order page (which is accesssible with the order number & email address used for the order), compare it with an existing copy (should it exist), and mail specified addresses when/if there are changes. Do this whenever (@hourly works fine for me), and forget about website visiting.
Bingo.
So, erm, just in case anyone else wants it (yes, the licensing blurb is probably about the same length as the code itself, i dunno why I bother, but maybe someone’s got some hints/tips/comments…), ‘dell-order-status‘ (it’s a tidied up version of the one I’m actually using, so i may need a nudge to update the web-version if I change the one in use)
