• Scratching An Itch With A Gem

    I love to read. I enjoy novels, science fiction, non-fiction, science and history. I also read a few technical books per year, which I review on this very blog. I was a bit late to the ebook party and preferred physical books. I received a Kindle as a gift for my birthday 3 years ago. From then on, I have been a convert: I love my Kindle and bring it everywhere.

    How To Test Multithreaded Code

    Mike Perham, author of Sidekiq, the popular Ruby queueing library, writes a great post on how to test multithreaded code. The first portion, deals with separating the threading portion from other logic, so that it can be tested with regular means. In addition, he details how using a callback and the native Ruby Mutex and ConditionalVariable one can test threading code, without using any sleep calls. Very informative post.

    Is Rest Best In A Microservices Architecture?

    Craig Williams discusses why REST over HTTP is not necessarily the best option for communicating between microservices. He illustrates two other options: Pipelines and messaging and talks about the pros and cons of each. It’s a topic that I have personally though about much and at work, we have started using messaging as opposed to REST for the reasons outlined in the article.

    Learn to Code: It’s Harder Than You Think

    As Mike Hadlow, the author states in the TL;DR:

    All the evidence shows that programming requires a high level of aptitude that only a small percentage of the population possess. The current fad for short learn-to-code courses is selling people a lie and will do nothing to help the skills shortage for professional programmers.

    The perspective and numbers in the article are particular for the UK, but I believe they apply equally well to the US.

    Phoenix Is Not Rails

    I have been following the Elixir community and the Phoenix framework in particular. I feel a certain familiarity between Ruby and Elixir, and Rails and Phoenix. Chris McCord, the creator of Phoenix writes, a thoughtful post on the differences, and more importantly why they matter. Sometimes, differences in Software Engineering can be esthetic only (e.g. plural vs singular database table names); Not so with these. He makes compelling arguments on the technical choices made in Phoenix.

    How To Charge For Open Source

    Mike Perham, the creator and maintainer of Sidekiq, explains how to go about making a business out of Open Source Software. Uncharacteristically for the internet, the comments for this post are actually very interesting, as are the links.

    What Is SemVer

    SemVer, short for Semantic Versioning, is a convention for software version numbering.
