I just finished up the book Ikigai (or rather, ordered collection of essays, email fragments and blog posts) by a guy named Sebastian Marshall.

Operators are one of the core components of any programming language. Knowing how they are classified and how they can be used is extremely important. This post might teach you some new operators. Since the samples are pulled from multiple languages, you may even learn something cool about a new language. Enjoy, and please point [...]
I’ve been working my way through some of the open courseware computer science materials that MIT hosts. The past few nights, I’ve been reviewing the “Practical Programming in C” lecture notes and assignments. For the most part, the first few assignments were really easy for me – few new concepts. One bit that tripped me [...]

If you weren’t aware of the full breadth of how the static keyword alters a variable, this post should be a mind blower. So, let’s start simple. Take the following example [...]
A continuation in my self-assigned crash course in design patterns, I’ve been learning more about the observer pattern recently. It’s a cool pattern, and I’m hoping I can convince some of you that it’s worth learning more about. I only have time for a quick post, and hopefully I can get in the major points [...]

Download dbase: http://pecl.php.net/get/dbase 2. Extract and cd into. 3. sudo phpize 4. sudo ./configure && sudo make && sudo [...]
Believe it or not, this is the easy part. There aren’t that many physical components that make up a small business network, and acquiring all of them should be both easy and fast. First, let’s start with a diagram (click to enlarge), and we’ll drill into each piece in more detail. So, basically your internet [...]
I’ve been working on a Linux driven network for my family’s small business, Froedge Machine. It’s been an awesome, engrossing experience so far working on this – and the farther I delve the more I realize just how approachable this type of project is. I’m far along enough in the project now that I can [...]
Number 5 of the 12 PCI compliance steps in the SAQ D is to “Use and regularly update anti-virus software or programs.” We all know that this *really* isn’t needed – but it’s in the PCI compliance requirements – so here’s an easy way to do it.
