As any web developer knows testing for cross-browser compatibility can be a time consuming process. To help ease this process Adobe has been developing BrowserLab intended to help simplify and speed up the process of testing for compatibility. Here’s Adobe’s description of their hosted solution BrowserLab:
BrowserLab is an online service that allows web professionals to test their websites on popular browsers and operating systems. Screenshots of actual browser renderings are generated in real time, with multiple viewing options to help pinpoint issues. Note Adobe Dreamweaver CS4 software users have access to additional functionality such as testing local and active content.
Google Chrome for Mac was released as an official beta a few days ago. If you are interested in getting the bleeding edge development version with even more features, there is a very easy way to do so.
One of the first hurdles individuals run into when breaking into web development is setting up a testing server. This often occurs when you create your first PHP page in Dreamweaver or other text editor and try to view it in your browser. Most likely, you see some bizarre ‘Unable to Connect’ message or even worse, a window pops up for you to download the file you are trying to view. These undesirable results are probably occurring because you haven’t set up your computer to be able to serve PHP pages. The good news is…you can now set up a PHP/MySQL testing server in minutes.
If you are a web developer, having some good “cheat sheets” is an excellent resource. There are some great ones available at
