Faster Command Line Tools in Nim

After having read the blog post titled Faster Command Line Tools in D by Jon Degenhardt on the D Blog, I was interested to see how Nim would stack up performing the same task. Rather than explain the task again, I might as well quote the reference post that inspired me: It’s a common programming task: Take a data file with fields separated by a delimiter (comma, tab, etc), and run a mathematical calculation involving several of the fields.

Using Nim with C# .NET

Nim is a statically typed programming language that compiles to C featuring a tracing garbage collector, zero overhead iterators, and powerful compile time evaluation of user defined functions. It features an indentation based syntax with a powerful AST based macro system. Thanks to the fact that Nim currently compiles to C, it can run on many platforms and architectures via a native binary. Cross compilation (for example, compiling Windows executables on Linux) is also possible with the correct compiler configuration.

Using Laravel's scheduled tasks with systemd timers

Laravel 5 includes a handy system to create scheduled tasks that are ran through the artisan console. In order to run these command automatically, the documentation recommends using a cron job to call the schedule:run artisan command every minute. One problem: minimal CentOS 7 installs do not come with cron installed. We can easily replicate this functionality using systemd timers however, without having to install any extra dependencies. The best resource for learning more about systemd timers I’ve found is the Arch Linux Wiki Page “systemd/Timers”, which goes into detail on the different types of timers (monotonic and realtime) as well as providing some example unit files.

Getting started with the D Programming Language on OS X Yosemite

The D Programming Language is a language with C-like syntax and static typing. It pragmatically combines efficiency, control, and modelling power, with safety and programmer productivity. In this post, I’m going to quickly walk through getting a working D compiler setup on OS X Yosemite, using Homebrew. I’m going to assume you’ve already got Homebrew installed and have a working installation. There are many guides on setting Homebrew up, so I’ll leave that to others.
