Php

API development methodology
I needed a way to create and connect only to those services I actually need to run. If I only need to connect to Redis, I don’t need to connect to MySQL as well. Leverage PHP language constructs to this end. Injecting dependencies should be language driven, not programmer driven. I want you to think about this. Language driven vs. programmer driven - this is the main point. When it comes to programmer driven dependency injection, it will happen that your programmer(s) will be using their time writing methods that will get, set and report missing dependencies.

On PSR-0 standards, namespaces and code (re-)use
When it comes to working on several projects with different people, having a set of standards to dictate code use and code re-use is a good thing to have. PSR-0 is one such accepted standard. It took a while to realize it, as I so often do, that many useful improvements to PHP mean a few steps forward, a few steps back. I’m going to try to list a few patterns which are the cause of some conflict when implementing PSR-0.

Optimization strategy
Sometimes it’s not about just optimizing CPU time away. Looking at the details I could optimize away a badly written SQL query along with some more trivial big-O problem in regard with sorting of video clips which I got out of serialized data. All from a few carefully placed calls. Reducing network bandwidth is just as important as CPU time.

In process performance statistics with Redis
Every once in a while you need to do a sanity check of your code, how it performs and what you can do to improve it. This is most apparent with a code-base that is developed and refactored over a period of several years. There can be several problems that negatively impact performance due to dependency issues or legacy code that should have been removed but was forgotten during a refactoring sprint.
