@kangax's ES6 quiz, explained

@kangax created a new interesting quiz, this time devoted to ES6 (aka ES2015). I found this quiz very interesting and quite hard (made myself 3 mistakes on first pass).

Here we go with the explanations:

Branch mispredict ............................ 5 ns                     on recent CPU
L2 cache reference ........................... 7 ns                     14x L1 cache
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns                     20x L2 cache, 200x L1 cache
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs 4X memory

Solid Base .htaccess

Creating a solid base for your .htaccess file. Currently includes RewriteBase, Security (against indexes, files, etc.), and Expires Headers (caching, performance).

  • The URL REWRITES would go at the top of the file.
  • The SECURITY and the WEB PERFORMANCE can go towards the bottom... before and WordPress or WP Super Cache items.
  • UPDATE 2013-08-21: Added code for forcing either non-www or www. on URLs. Also added the MultiViews option.
  • UPDATE 2013-08-23: Added specific code for wp-config.php
  • UPDATE 2013-10-04: Increased favicon expire time.
  • UPDATE 2014-02-05: Removed the Force URL rewrites since there's more than one option.
