When its time to scale, its time to scale! Among other things scaling includes redundancy.
One way to achieve better results is with MySQL database replication. I think as far as “how-tos” go in terms of detail this is a pretty good example and walk-through.
This is from http://www.howtoforge.com/
I think that with the more popularity that CSS3 gains and the more standard it becomes, one of the mysteries is what browsers support is offered for the new features in the release.
Luckily if you are looking for a pretty cool, and up-to-date compatibility listing of CSS selectors and pseudo selectors browser compatibility, then i think that this is a good link to take a look at.
They offer a pretty in-depth look at all the various css selectors, with their releases from 1 to 3, and lets you know EXACTLY if there is explicit support for that particular browser.
Anyone who has had to deal with the fabled creature that is IE6 can attest to how handy this would be
If you have ever had to work with PHP the luxury of becoming used to simple things like request parameter processing can be lost. Sometimes you have no alternative if you are working with a simple HTML file.
Hence comes in this nifty little jquery plugin, it allows you to grab parameters from the url and then process them accordingly. One way that this could be useful is if you wanted to detect a page state or to display or hide an element depending on the state.
You can download the plugin here and its also fairly light too which is good.
Here is an example of the source, its relatively short so i am posting it here and you can give it a try:
