  What to Look for in PHP 5.4.0

PHP 5.4.0 will arrive soon. The PHP team is working to bring to some very nice presents to PHP developers. In the previous release of 5.3.0 they had added a few language changes. This version is no different. Some of the other changes include the ability to use DTrace for watching PHP apps in BSD variants (there is a loadable kernel module for Linux folks). This release features many speed and security improvements along with some phasing out of older language features (Y2K ...

  Three things you should never put in your database

As I've said in a few talks, the best way to improve your systems is by first not doing "dumb things".

Spinlock and mutex are two important concepts in multithreading programs. They are used to lock some shared resource to prevent concurrent access which may affect data consistency. But they do have differences, what are the differences? when should we use spinlock instead of mutex? The Theory In theory, when a thread tries to lock a mutex and it does not succeed, because the mutex is already locked, it will go to sleep, immediately allowing another thread to run.

  Obviously Correct

What do automatic memory management, static types and purity have in common? They are methods which take advantage of the fact that we can make programs obviously correct (for some partial definition of correctness) upon visual inspection. Code using automatic memory management is obviously correct for a class of memory bugs. Code using static types is obviously correct for a class of type bugs.
