Over the years of using Linux as my primary and only OS I had to embrace some unavoidable facts. First, things tend to change and complex things tend to break. Second, reinventing the wheel almost never pays off. And finally, it’s not that hard to make a new habit and sometimes it’s better than adjusting your workstation to your “intuitive” understanding that may change very soon. So years ago I decided to only use the most common software ..

I should know better than to use a latest tag in a Docker image. I’d never do this at work, so why did I do it in my hobby project? I blame Go’s nature of dealing with package versioning (that is, the lack thereof) for putting me in the “let’s use latest!” mindset (and yes I know they’re working on it). Anyway, I should know better, but here we are, writing this post. It’s going to be a short one.

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..

Wanted to try out some code, but needed to ensure never checked in. Git pre-commit hooks are handy in this space. Add the following script to search for either @COMMITFAIL or @NOCOMMIT in the staged files. If found, attempts to commit will fail.

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..

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..

I've been using FreeBSD as my daily driver at work since December. I've successfully done my job and I've learned a hell of a lot forcing myself on CURRENT... But there's been a number of issues with it that have made it difficult to keep using, so I replaced it with Arch Linux yesterday and I no longer have those issues. This is not the first time I've forced myself to run FreeBSD and it won't be the last. The FreeBSD setup I have a Dell ....

I found this article to be a very astute observation that it can be all the “little trade-offs” that can add up to cause issues. The article highlights it from the perspective of a leader who can make small decisions, usually around putting something off or taking a short cut, that can add up to impact their work and those around them.

One of the more popular articles in the financial independence blogosphere is Mr. Money Mostache’s The Shockingly Simple Math Behind Early Retirement . If you haven’t read it, check it out. While I found it interesting, I think that the simple math is lacking, well, math, so I wanted to dig a bit deeper and figure out where the numbers came from.

Still wondering why it all works? Why this black square does things? Lets go deeper. Previously I explained a bit about processor architecture. It’s the basis of the chip. It’s a fundament. You won’t find anything about an UART in a Technical Reference Manual of Cortex-M4 . It’s just not a part of this fundament. When you get an STM32 microcontroller based on the Cortex-M4 architecture you just get microcontroller made by ST wh..

Most post in this category are unfinished, imperfect, lack the polish a proper blog article should have, very often they have typos and even some time unfinished sentences. So why even bother? Well, because life isn’t perfect, and most imperfect. But it is important to get going anyway. It is important to persist. I know as I keep doing it it helps me shape my thinking. Mostly I avoid accumulating ideas in my head.
