Post-REST
More or less all the big APIs are RESTful these days. Yeah, you can quibble about what “REST” means (and I will, a bit) but the assertion is broadly true. Is it going to stay that way forever? Seems unlikely. So, what’s next?

Pipenv: promises a lot, delivers very little
Pipenv is a Python packaging tool that does one thing reasonably well — application dependency management. However, it is also plagued by issues, limitations and a break-neck development process. In the past, Pipenv’s promotional material was highly misleading as to its purpose and backers.

C Portability Lessons from Weird Machines
In this article we’ll go on a journey from 4-bit microcontrollers to room-sized mainframes and learn how porting C to each of them helped people separate the essence of the language from the environment of its birth. I’ve found technical manuals and videos for this article to help bring each computer to life.

Pointers Are More Abstract Than You Might Expect in C
A pointer references a location in memory and dereferencing a pointer refers to the lookup of the value of the memory location the pointer references. The value of a pointer is a memory address.
