New Stickers E-Commerce Website Launch

taf2 — Sat, 13 Feb 2010 14:44:21 +0000

We have just announced our new stickers store Wall2Wall Stickers. Check it out, let me know what you think. I would love to know if you see any glaring issues.

To date we have had modest traffic and a few purchases in only the first 3 days of making the site available – we’re optimistic about the site. We built it on the spree e-commerce platform and have made some fairly major changes, but all in all have been very happy with the platform and are very much looking forward to the latest from Spree Edge.

Webkit, Ruby and Gtk+

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.

Ruby and Time.now.httpdate

taf2 — Tue, 26 Jan 2010 22:11:02 +0000

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

hex2rgb Javascript

taf2 — Fri, 15 Jan 2010 01:58:06 +0000

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!

Here’s an example of why I really enjoy using curb. Curl::Multi.get interface is just so easy.

High Availability with Unicorn Zero Down Time Deploys

taf2 — Thu, 17 Dec 2009 20:04:32 +0000

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.

Now some important things to note, in the github write up they had the QUIT signal sent in the before_fork. I am pretty certain that this is incorrect and it should be in the after_fork.

Here is the unicorn configuration I am currently using:

Also, I have a custom spin script:

In the youtube video I use the reload action

Sitemaps and Siege

taf2 — Thu, 17 Dec 2009 19:03:05 +0000

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.

Updated Theme

taf2 — Wed, 16 Dec 2009 23:19:54 +0000

Okay, I really liked this theme last year when I installed it but today I decided it was time for a change… Well a minor change, I hacked up the theme to support a variable width grid. Setting a min-width and width:%% to allow the content area expand.
