(Jul 31) #distributed systems Save to Pocket

Distributed systems take a little getting used to, especially if you're using them to store data. Why? Well because sending a request to a database isn't usually instantaneous. Roberto Vitillo's article focuses on explaining how database requests are handled, what strong, sequential, and eventual consistency are, and finally the PACELC theorem. Ultimately "the stronger the consistency guarantees are, the higher the latency of individual operations is, and the less available the store becomes when failures happen".

Working with low level languages can be a headache, because you have to consider possible errors or bugs that might arise from memory mismanagement. However, getting down and dirty on this level is pretty much unavoidable if you want to optimize something. In this article, the author compares ownership and memory in C to Rust. The author highlights the disadvantages of silent contracts and underlines the benefits of encapsulation in Rust when it comes to code "safety".
