(edit) PHP, node
I normally don't do this. When I see someone write a blog post I don't agree with, I often just dismiss it and go on. But, this particular one caught my attention. It was titled PHP vs Node.js: Yet Another Versus. The summary was:

Node.js = PHP + Apache + Memcached + Gearman - overhead

What the f**k? Are you kidding me? Clearly this person has NEVER used memcached or Gearman in a production environment that had any actual load.

Back in the day, when URLs and filesystems had a 1:1 mapping, it made perfect sense to have a web server separate from the language it is running. But, nowadays, any PHP app with attractive URLs running behind the Apache web server is going to need a .htaccess file, which tells the server a regular expression to check before serving up a file.

Indexes are a very important part of databases and are used frequently to speed up access to particular data item or items. So before working with indexes, it is important to understand how indexes work behind the scene and what is the data structure that is used to store these indexes, because unless you understand the inner working of an index, you will never be able to fully harness its power.
