The ruby bindings for Gnome are really nice. I’m amazed at how easy this was.
Sure it’s not Chrome, but not bad for an embedded browser. Oh and check out how simple this is:
require 'webkit'
win = Gtk::Window.new
wv = Gtk::WebKit::WebView.new
win.add(wv)
win.show_all
wv.open('http://www.google.com/')
Gtk.main
Try it out! The bindings are on github.
I keep running into this when I need a httpdate. Make sure to always require ‘time’
e.g.
Time.now.httpdate -> raises exception
and
require ‘time’
Time.now.httpdate ->Tue, 26 Jan 2010 22:10:45 GMT

While experimenting with canvas tag today I needed a good way to take a hex value and convert it to RGBA. I went searching and found some solutions, but nothing that really seemed complete. I wanted a single function that didn’t call eval or pollute the environment with globals… Maybe I could have looked harder but here is what I came up with.
I know hex values don’t include the alpha value in rgba – this function gets you the RGB values so you can mix in the alpha value.
Update:
Duncan posted this solution that is much better than mine!
If you have not heard of unicorn and you actively develop ruby applications for the web. It is no doubt well worth your time to check it out. Github has a very good write up about unicorn that is definitely worth reading. Let me first show you this quick video of deploying to our yet to be released client site while sieging.
If you are like me and always want to test the performance of your sites before releasing them to the public eye and you have an interest in publishing sitemaps to google and friends. This handy ruby script might be just the thing for you.
Assuming you already have your sitemap.xml file, if not try googling…
Next run the ruby script, given the sitemap.xml file as the first argument:
ruby sitemap-to-siege.rb sitemap.xml
That will create the urls.txt file.
Now run siege:
siege -c50 -t1M -f urls.txt
Note on mac you can install siege with
sudo port install siege
On redhat:
yum install siege
Or grab the source.
