  That’s Not TDD

A few months ago I was visiting a client who was having a lot of problems using TDD. “It takes over half an hour to run our unit tests,” he said. “You are not doing TDD,” I said. “In order for tests to be valuable all of them must run fast—within a few seconds, or developers will stop running tests frequently.” “But how to I make them run fast?” he asked, “Just connecting to the database takes 30 seconds” So I showed him a techn...

Have you ever seen "<=>" in a SQL query while using MySQL? Does it mean less and equals to and greater than? Actually if you consider it as the union of <= and =>, great, you are close to it. This is one form of equal operator in MySQL, it has the similar meaning to the = operator with some subtle difference. According to MySQL documentation, <=> is NULL-safe equal.

  PHP Multithreading – Faking It

PHP doesn’t really support multi-threading per se but there are ways to do “fake” multithreading. Here’s one I saw in the PHPClasses.org newsletter – Multi-thread Simulation. Note that this class is intedend for use on a webserver, as opposed to running PHP scripts from a command line (or similar).

As the web evolves, Google’s crawling and indexing capabilities also need to progress. Weimproved our indexing of Flash, built a more robust infrastructure called Caffeine, and we even started crawling forms where it makes sense. Now, especially with the growing popularity of JavaScript and, with it, AJAX, we’re finding more web pages requiring POST requests -- either for the entire content of the page or because the pages are missing information and/or look completely br...
