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.

Effective Ruby LiveLessons is a video training course by Sam Phippen, based on the excellent Effective Ruby book written by Peter Jones (see my review of that book).

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. For a more in-depth conversation into the same topic, hear (or read the transcript) of Mike’s guest appearance at the Ruby Rogues Podcast

What Is SemVer

SemVer, short for Semantic Versioning, is a convention for software version numbering. I have been using it very successfully at work with for internal gems and bundler pessimistic locking (~> operator). In this post Richard Schneeman, explains the practical aspects of choosing a release number, including security releases.

Last Saturday (11/14/2015) I attended my first code retreat, hosted by the kind folks at Pluralsight. The event was part of the Global Day of Code Retreat. 144 cities participated in the event, and for the first time San Diego was one of them.
