Posted on March 12, 2022, Level intermediate Resource Length medium
TypeScript's never type is very under-discussed, because it's not nearly as ubiquitous or inescapable as other types.

Discarding magic feathers -- Going frameworkless in Scala
Posted on February 25, 2022, Level intermediate Resource Length medium
A good few years back, I looked into building a Scala webapp using Java's little-known provided HTTP server rather than one of the many frameworks already out there during my 10% time at Springer Nature. I made a mistake here - to avoid those frameworks I built my own framework to route requests within a webapp. I called it Sommelier, and it is now hidden away in a private github repo as really, we don't need another of those. Maybe we don't need any of them at all. By Jim Kinsey.

Controlling concurrency in distributed systems using AWS Step Functions
Posted on January 29, 2022, Level intermediate Resource Length medium
Managing concurrency in distributed systems can be challenging. In a monolithic application, you use familiar concepts such as in-memory locks to avoid overloading a database or prevent overwriting a customer record by two users at the same time. With a distributed system, where your application is dispersed across computing environments without shared memory, these methods are no longer available to you. By James Beswick.

Posted on January 17, 2022, Level intermediate Resource Length medium
A few weeks ago, an interesting issue appeared on our GitHub tracker. It was reported that, despite our care in designing the driver to be efficient, it proved to be unpleasantly slower than one of the competing drivers, cassandra-cpp, which is a Rust wrapper of a C++ CQL driver. By Piotr Sarna.
