A few things we need to get out of the way. First, I didn't make any of this stuff, except for a font that only looks decent in DOS and isn't strictly ASCII anyway. Next, the comments you'll find from time to time are from the authors which, as I believe I've mentioned, aren't me. If I do feel a need to make a comment, I'll preface it with "Editor's Note:". Finally, I never remove initials or other "signatures" from ASCII Art. If you see something of yours that doesn't have your sig, that's the way I found it.

Return to BASIC - A new BASIC for Linux computers.

RTB is a modern BASIC – it has while/until looping constructs and named functions and procedures which can have local variables and be called recursively. It has simplified colour scheme (or you can use all 24-bits if you like), and the usual point, line and shape drawing primitives as well as some nice turtle graphics commands.

Git’s history is based on a DAG of commits. Branches (and “refs” in general) are just transient labels that point to specific commits in the continually growing commit DAG. As such, the relationship between branches can vary over time, but the relationship between commits does not.

This HTML5 app takes away all of the pain of creating font files for simple uses such as building icon fonts. IcoMoon comes with a number of icon sets already loaded, and you can add more to your library, most of which can be used for free (check the licensing). If you are looking for fairly standard icons, such as “file download” and “shopping cart,” then you may find that using one of these is preferable to creating your own.

There are plenty of icon fonts out on the web, but they often contain icons you don’t need, adding weight to your website and making it load slower. A custom icon font will load faster, as it only contains the characters and icons needed for your project.

A big challenge that loomed when I embarked on the Statecraft was proper implementation of a hexagon grid. I felt the move to a hex grid was one of the few things that Civ V actually got right, and had the potential to bring a more interesting military layer to the game. Unfortunately, it was done at the expense of…everything else.

Taking specific gameplay mechanics aside however, a poorly implemented hex grid, at the base technical level, has the potential to create massive headaches for me (the programmer) and millions of wasted CPU cycles. The reason for this is the very nature of trying to assign Cartesian coordinates to a honeycomb grid. Quite frankly, all the existing works browsable through Google searches on the subject of coordinate systems on hex grids are pretty piss poor, needlessly complex, or just flat out wrong; I would have to tackle the topic myself.

The TGSK is a simple, open-source (MIT licensed) javascript game engine designed specifically to help you skip "square one" on your way to creating a great Tower Assault or Defense game. Included in the github source repository are project files for Windows 8 Store apps that run on win8 tablets, desktop, and windows RT devices, as well as a project that compiles to Windows Phone 8. In addition, the game runs great on all modern desktop web browsers.

Everyone knows that error handling is important, but to what end? In fact, error handling plays many roles, from reassuring the end-users, to helping identify trouble spots in an application, to siphoning off potential security holes in the code. In this installment on error handling in JavaScript, we'll be taking a look at how to code your exception handling in JavaScript in a way that takes browser discrepancies into account.

A simple javascript library to turn text into vector UML sequence diagrams. Heavily inspired by, who offer a serverside solution. We use Jison to parse the text, and Raphaël to draw the image.

This is a tool for creating
syntax diagrams,
also known as railroad diagrams, from
context-free grammars
specified in
EBNF. Syntax diagrams have
been used for decades now, so the concept is well-known, and some tools for diagram generation are
in existence. The features of this one are
usage of the W3C's EBNF notation,
web-scraping of grammars from W3C specifications,
online editing of grammars,
diagram presentation in SVG,

and it was completely written in web languages

HTML is an amazing language for creating static documents, but it was never designed for interactive web apps. Many libraries try to get round HTML's limitations, but very few tackle them head on.

The aim of dimple is to open up the power and flexibility of d3 to analysts. It aims to give a gentle learning curve and minimal code to achieve something productive. It also exposes the d3 objects so you can pick them up and run to create some really cool stuff.
