I thought, it might be a cool idea to actually proof that something like that should be possible within a few lines of code. No C code, no Objective-C, even more simple: AppleScript (and a little bit of Bash scripting).

However, so I just took about an hour and a half and wrote down this little bad boy:

global used_codes
global code_used

on run
	set used_codes to {}
end run

on idle
	set promocodes to paragraphs of (do shell script "/opt/local/bin/wget --quiet -O - http://twitter.com/statuses/user_timeline/166916511.rss | while read sentence; do for word in $sentence; do echo $word | grep '^[A-Z0-9]\\{12\\}' | sed 's/\\(.\\{12\\}\\).*/\\1/'; done; done | sort | uniq")
	repeat with promocode in promocodes
		set code_used to false
		repeat with used_code in used_codes
			if promocode = used_code then
				set code_used to true
			end if
		end repeat
		if code_used = false then
			tell application "iTunes"
				launch
				activate
				open location "itmss://phobos.apple.com/WebObjects/MZFinance.woa/wa/freeProductCodeWizard?code=" & promocode
				copy promocode to the end of used_codes
				set used_codes to used_codes & promocode
			end tell
		end if
	end repeat
	return 30
end idle

Simply hack it into your AppleScript editor and save it as “Application” with the “Stay Open” option clicked. Now after double-clicking the file that has just been created the script starts fetching a Twitter RSS-feed (in this case @verbsapp’s, heh) every 30 seconds, grabs all iTunes promo-codes it can find and automagically redeems them in the iTunes store. If the could is still valid – lucky you. If not, better luck next time! In any case each code will be added to a temporary “black list” so it won’t be redeemed again.

Feel free to customize and use this script! GNU GPL v2 and stuff. Enjoy.

//update: I’ve just adapted the script a bit more to include promo codes with more than 12 characters length. Besides, I’ve applied John’s “patch” to it – thanks for that one John!

global used_codes
global code_used

on run
	set used_codes to {}
end run

on idle
	set promocodes to paragraphs of (do shell script "for word in `/usr/bin/lwp-download 'http://twitter.com/statuses/user_timeline/166916511.rss' -`; do echo $word | grep '^[A-Z0-9]\\{12,16\\}' | sed 's/\\(.\\{12,16\\}\\).*/\\1/'; done | sort | uniq")
	repeat with promocode in promocodes
		set code_used to "false"
		repeat with used_code in used_codes
			if promocode as string is used_code as string then
				set code_used to "true"
			end if
		end repeat
		if code_used is "false" then
			tell application "iTunes"
				display dialog "Found a new code: " & promocode & " - use it now?"
				launch
				activate
				copy promocode to the end of used_codes
				set used_codes to used_codes & promocode
				open location "itmss://phobos.apple.com/WebObjects/MZFinance.woa/wa/freeProductCodeWizard?code=" & promocode
			end tell
		end if
	end repeat
	return 30
end idle

So, what’s new in 0.3? Well, just about everything. I’ve renamed the bundle (at least its metadata), since webOS is not just limited to the Pre and I’ve modified the shortcuts of existing features to fit TextMate’s styling guidelines a bit better. I’ve also created some snippets which can be used for faster code-writing now and in addition to that, I’ve implemented a very own language for the bundle, which can’t be found in the document type picker named as “Mojo”. “Yeah baby!”, as Austin would say now. Actually, yet it’s just a copy & paste of the JavaScript-language implementation in TextMate, but I’m planning to extend it to fit the Mojo-framework even better.

The TextMate bundle is now also available on GitHub, for everyone who can’t wait for me packaging the releases and releasing them here. If you have any ideas for improvement, feel free to contact me by mail or just leave some lines here on my blog.

Enjoy!

The last time I check out the project, there was no such daemon for Unix(-like) platforms but Mac OS X itself. I decided to take a quick look at the independend istatd Project on Google Code and give it a shot. I fetched the sources, built them on a Debian Lenny and ran the daemon with a slighly modified configuration – and it worked!

I found it pretty cool. Actually, I found it so cool that it was the reason for me to buy the actual iPhone App. I have no Mac OS X Servers I’d like to monitor, but I could think of plenty of Linux machines which I’d like to keep an eye on – not as an replacement for Nagios, just as a solution for quick-live-monitoring.

However, I decided to build a Debian package, to make it easier to deploy the istatd on a couple of machines. I attached the Debian package to this post, so you can just download and install it on your Lenny machines. Warning: It’s not a clean and tidy built, lintian conform packge! I just hacked it together to have something that “just works”. And that’s what it actually should. Besides, be warned that the daemon takes quite long to shut-down, due to the fact that I’ve just used the regular /etc/init.d/skeleton to create an own /etc/init.d/istatd script, without going into deep workflow-checks. Here, the script takes something around half a minute to kill the istatd.

Anyway, now I’m going to take a look at the sources and see, if I could probably commit some enhancements to the projects. The last time I was doing C++ is *quite* a time ago, but it shouldn’t be too hard from what I’ve seen so far. On the project’s site it says that there’s no support for fans and temperature measuring, yet. I will check whether it’s possible to use lmsensors for getting those information and maybe hack it in – or even rewrite the daemon in C, what would be the best to do anyway.

Oh well, however. Enjoy the package.
