According to the site: God is an easy to configure, easy to extend monitoring framework written in Ruby.
While god is mainly intended for monitoring mongrels it is also a great way to keep an eye on apache itself. Below is our config for watching apache.
%w{80}.each do |port|
God.watch do |w|
w.name = "apache"
w.interval = 30.seconds # default
w.start = "apachectl start"
w.stop = "apachectl stop"
w.restart = "apachectl restart"
w.start_grace = 10.seconds
w.restart_grace = 10.seconds
w.start_if do |start|
start.condition(:process_running) do |c|
c.interval = 5.seconds
c.running = false
end
end
end
end
The code is pretty self-explanatory. We’re just looking to make sure apache is up every 5 seconds.
After gem installing god, save the configuration file anywhere you want and kick if off with this command:
god -c /path/to/your_conf.god
That’s it. To test, kill apache and in less than 5 seconds it will be back up and running.
I’ve recently stopped using javascript to do rollovers when reasonable. It’s much nicer because you don’t have to write onmouseover or onmouseout events, and it works without javascript. It’s also prevents a weird ‘blink’ (especially in IE) when rolling over if the image isn’t loaded in cache.
The trick is to create one image that has both states and assign the background-position of the hover state.
Using the following image and css, you don’t have to worry about javascript.
This looks like a good one to add to your RSS reader.

So looks like the new version of IE is going to be called… IE8. Not very exciting but it’s funny to see someone at MS make fun of their confusing product names.
Linus Torvalds, creator of Linux, discusses his distributed source control system Git at Google. Features some pretty amusing quotes like “If you’re using CVS you should be in a mental institution” and “I would never, ever trust Google to maintain my source code for me, I’m sorry, you’re just not that trustworthy”.
A List Apart has a great writeup on the forthcoming HTML5 specification.
Goodies include customizable inline audio and video players built right into the browser (goodbye, flash video players), and much cleaner HTML due to the use of new tags (HEADER, NAV, ARTICLE, SECTION, ASIDE, FOOTER = goodbye DIV).
The bad news? It’s still 10-15 years from fruition.
Here is a great example of giving users a really simple solution without a lot of technical overhead. Dave Thomas of the Pragmatic Programmers describes how they had set out to build a robust wish list feature into their online bookstore with referrals, e-mails, messaging, automated suggestions, etc. Then they pulled back and released this instead: Pragmatic Bookshelf Wishlist. Doesn’t get much easier than that.
