When making the new design of this blog, I inevitably come to the dilemma of whether to use traditional CSS sprites (i.e. to use background image positions to locate the images) or to use Data URI sprites (i.e. to use Data URI / MHTML to replace the actual image files).
First of all, during the design and development stage, everything was built without any sprites in mind. It is just so much easier to build the template without worrying about background image positions.
After the template is fi...
After spending the weekend coming up with the design, one night of chopping and slicing and half a night of Tumblr themeing, I have finally done it!

Thanks to 960.gs and the Variable Grid System, they made making layout so easy!
The theme is tested in all major browsers, except IE6. Let me know what you think! :-)

Dear Photoshop, please don’t, just don’t.

Don’t you just hate that. Fortunately I have the ‘CMD + S’ syndrome.
Today Opera has released its latest and greatest version of Opera browser 10.5 Beta for Mac. It features speed enhancement as well as a unified Cocoa interface. Just how speedy is it exactly? Let’s test it out against other major browsers.
The benchmarks were run on my Macbook Pro (OS X 10.6.2, 2.53GHz CPU, 4GB RAM). I have performed three benchmark tests from Dromaeo - All JavaScript Tests, DOM Core Tests and JavaScript Library Tests. The following browsers are used:
- Firefox 3.6
- Minefi...
So we want to dynamically instantiate an object (i.e. convert a string to a class constant).
Instead of doing this:
@dynamic_var = "User"
eval(@dynamic_var)
You can do this:
@dynamic_var = "User"
@dynamic_var.constantize
See more about the constantize method in Rails’s API.

So I received my Dell U2711 today, even though I was told by a sales rep it will be delivered tomorrow. ;-)
The thing is, I ordered a Mini DisplayPort to DisplayPort connector and it’s not here yet. So instead of enjoying the native 2560x1440 resolution, I have to put up with 1920x1080 for now. It’s still a nice upgrade from my ViewSonic 20" (1680x1050).
A few days ago I was conducting some preliminary tests and benchmarks on a couple of NoSQL solutions such as Redis, Cassandra and Riak.
As expected, Redis performed really really well, its speed is unmatchable by Cassandra and Riak.
However, that’s not the point.
One thing I noticed is that quite a few people don’t really get what ’scalability’ actually means. In this case, Redis does not scale (yet), so comparing the raw performance (on a single machine) isn’t entirely useful.
Both Cassandra...
I’m hoping to post more regularly by having this Tumblr blog. :)
