Disabling Safe Sleep After November, 2012
In early November, 2012, Apple issued a graphics update for all mid-2012 MacBooks. In a continued streak of stupidity, however, this update forces your Mac to use "Safe Sleep". This means that the entire contents of your RAM is written to your disk every time you put your Mac to sleep.
This is retarded on the scale of the Titanic's navigational plan for two reasons:
1) Your Mac likely has 8 or 16GB of RAM. This is a ton of wasted disk space; especially on MacBook Airs that ship with only 256GB SSDs to begin with.
2) SSDs wear out as you write to them. Each cell of a SSD can only be written to a certain number of times before it becomes read-only. If you put your computer to sleep many times a day, OS X is slowly but surely destroying your SSD with unneeded write cycles.
Worst of all, the graphics update makes it IMPOSSIBLE to turn off safe sleep using the standard approach you'll find on Google:

The new Secure Password Hashing API in PHP 5.5

The new Secure Password Hashing API in PHP 5.5

The [RFC for a new simple to use password hashing API][rfc] has just been accepted for PHP 5.5. As the RFC itself is rather technical and most of the sample codes are something you should not use, I want to give a very quick overview of the new API:

Why do we need a new API?

Everybody knows that you should be hashing their passwords using bcrypt, but still a surprising number of developers uses insecure md5 or sha1 hashes (just look at the recent password leaks). One of the reasons for this is that the crypt() API is ridiculously hard to use and very prone to programming mistakes.
