Writing a JSON parser is one of the easiest ways to get familiar with parsing techniques. The format is extremely simple. It's defined recursively so you get a slight challenge compared to, say, parsing Brainfuck ; and you probably already use JSON. Aside from that last point, parsing S-expressions for Scheme might be an even simpler task. If you'd just like to see the code for the library, pj, check it out on Github . What parsing i....

Took me a little while to get into this book. It starts out in a school where a pupil spots a spaceship from his favourite video game. This then moves on to it being a precursor to an invasion by the aliens from the video game and the game itself was actually put together as training so the players could pilot drones in the war. A slightly surreal concept but pretty well executed. The “twist” with the main characters dad is a bit contrived ..

I have been very fortunate in my career to have some exceptional bosses that have had a massive impact on my career.

I had read a lot of good things about this book and it had sat on my Kindle for a long time. Really enjoyed the first half of the book but thought the second half was more focused on things that weren’t relevant to me. There were some statements made that were clearly opinions but were stated as facts. Overall a bit disappointing.

There is definitely an intimidation factor some people feel about integrating things into Ember apps. While there are plenty of things I want to make easier too, I think a large amount of the perception only comes from lack of good learning materials. Toward that goal, I made this screencast

Testing mobile applications is not always an easy feat. In addition to defining what to test and determining how to write those tests, actually running tests can also be problematic — in particular, UI test suites running on real mobile devices or emulators sometimes run for an extensive amount of time.

Time sure is flying. My son is already over a month old. I finished my second-to-last (penultimate!) class for my Master’s degree. And it’s already another month, so time to report what I read last month.

Alarm goes off, time to wake up. Snooze alarm, and then repeat: check email, check Facebook, check Twitter, check Snapchat, rinse; repeat again; no new posts? Check again. No second spared to compose a thought; dreams fade away. Day continues just the same way — rise, rinse, repeat, repeat. Can’t spare time to sit and relax, can’t let your mind wander not five minutes, no unstructured thought or daydream; just repeat. Every moment captures ....

Although the decision to include X-Pack sparked some confusion and disgruntle in some people due to having non Apache licensed code being present in the repo and the distrubitions; they are easily removable if any of them is a concern to you. SQL support was announced in ElasticON and there is a comprehensive presentation by Costin Leau. I was pretty excited about the support, because we use Elasticsearch for storing metrics and logs and it..

When GlusterFS nodes get isolated, you can end up with a condition known as split-brain - basically one (or more) nodes is aware of changes that the others are not. Depending on how bad the split-brain is, and what it effects, it has the ability to completely ruin your day. One of the first things you want to do, once you become aware of the issues, is (if at all possible) cease all writes to the volume on all nodes - you don't want t..

Testing with Laravel is very easy, but it can be a nightmare when the tests depend on Events and Listeners. In this post I’m gonna show you how you can simplify and improve those tests. Laravel is one of the most popular PHP frameworks nowadays, and I’d say its Event handler is one of the … Continue reading Solitary or Sociable? Testing Events and Listeners using Laravel

So, you’ve got a program that’s using more and more over time as it runs. Probably you can immediately identify this as a likely symptom of a memory leak. But when we say “memory leak”, what do we actually mean? In my experience, apparent memory leaks divide into three broad categories, each with somewhat different behavior, and requiring distinct tools and approaches to debug. This post aims to describe these classes, and provide tools and..

I mentioned before that I’m really behind on the Facebook Clone module but at least I was able to release the first few lessons by today which makes it fit into an April deadline. I’ll try to release new lessons every day so we can have the full module out before the end of May. At that point I’ll release two new modules during June. The new Facebook Clone is similar to the Uber clone in some regards and also very different:

Introduction One day I was talking to Damian Gryski in Slack about some performance improvements he made to his go-metro package. When I first looked at the changes I was completely confused how this could have any effect on the performance of the code. I felt the code was more readable, but more performant? I didn’t see it. Then Damian started to talk to me about a compiler optimization called Bounds Check Elimination or BCE. The id..
