PHP Comparisons

If there is something every developer (not just PHP) should know, it's when to use a strict equality operator. Interestingly enough, using empty() in PHP has exact behavior as checking loose equality with `== false`. This whole thing was inspired (and partially ripped off of) the JavaScript Equality Table. The design caught my eye, more than anything. I'm kinda wishing most if not all languages would have this kind of basic reference.

API Backpressure

It's days like this where I love my job. I'm implementing back pressure for API calls that communicate to an external service. Depending on how overloaded the external service is, my API interface adapts to use caching more extensively, or to use a service friendly request retry strategy, minimizing impact on infrastructure and possibly even resolving problems when they occur. This is done by keeping track of a lot of data - timeouts, error responses, request duration, ratios between failed and successful requests,.
