I was navigating the web using Stumble and I saw an interesting post that enumerate 40 tips for the optimization of your PHP code so I decide to post this tips on mi site.

If a method can be static, declare it static. Speed improvement is by a factor of 4. echo is faster than print. Use echo’s multiple parameters instead of string concatenation. Set the maxvalue for your for-loops before and not in the loop. Unset your variables to free memory, especially large arrays. Avoid magic like __get, __set, __autoload require_once() is expensive Use full paths in includes and requires, less time spent on resolving the OS paths. If you need to find out the time when the script started executing, $_SERVER[’REQUEST_TIME’] is preferred to time() See if you can use strncasecmp, strpbrk and stripos instead of regex str_replace is faster than preg_replace, but strtr is faster than str_replace by a factor of 4 If the function, such as string replacement function, accepts both arrays and single characters as arguments, and if your argument list is …

Just a few minutes ago Apple announce the creation of a SDK for developers this February so they can create third party applications for iPhone and iPod.

Here is the complete story:

Third Party Applications on the iPhone

Let me just say it: We want native third party applications on the iPhone, and we plan to have an SDK in developers’ hands in February. We are excited about creating a vibrant third party developer community around the iPhone and enabling hundreds of new applications for our users. With our revolutionary multi-touch interface, powerful hardware and advanced software architecture, we believe we have created the best mobile platform ever for developers.

It will take until February to release an SDK because we’re trying to do two diametrically opposed things at once—provide an advanced and open platform to developers while at the same time protect iPhone users from viruses, malware, privacy attacks, etc. This is no easy task. Some claim that viruses and malware are not a problem on mobile phones—this is simply not true. There have been serious viruses on other

Your easiest choice is one of those LCD cleaning solutions they sell in places where they sell computers. But they’re expensive, and why bother when you can make your own solution for next to nothing?

What you’ll need:

Distilled water (available at your supermarket; tap water leaves streaks and minerals). White vinegar (you may substitute isopropyl alcohol; either way, make sure these substances are diluted before they come near your screen). A clean, soft cloth (never use any kind of paper product). A spray bottle.

Directions:

In the spray bottle, mix the distilled water and alcohol/vinegar, in a 1:1 ratio. Turn off the LCD display. Spray the mixture onto the cloth, never directly onto the screen. Wipe gently – oh, so gently – from top to bottom. Do it horizontally, too, if you think that leaves a cleaner result. Let the screen dry before turning it back on. Hands Off!
