Colorful source code in Terminal

Often it is quicker to take a look at a source code file in Terminal using the cat or less commands, instead of starting up an editor, especially if you don’t need to make changes. However, like myself, most developers are used to syntax highlighting, or presenting source code in various colours. It makes the different elements in the source code stand out, and helps with comprehension. I find that the older I become, the more I need syntax highlighting, and I think back to a time when it was not so common, amazed that I could make sense of anything. Read more →

Time signals with the Raspberry Pi

Time signals have been broadcast by various radio stations for almost 100 years, usually “every hour, on the hour”, or every 60 minutes. The tradition was started by the BBC, but has been adopted by many national broadcasting companies and other broadcasters as a way of informing their listeners about the passing of time. The history of the Greenwich time signal, or “the BBC pips” is detailed in Mike Todd’s article. Read more →

Book review: Data Science at the Command Line

No matter how handy graphical user interfaces are, the good old command line remains a useful tool for performing various low-level data manipulation and system administration tasks. It is the fallback when you need to do something that has no way of graphical control. Being much more expressive and open-ended than a predefined set of controls, the command shell is the ultimate control environment for your computer. Data science has become one of the most intensely practised computer applications, so it is no wonder that it also benefits greatly from the hands-on control approach of the command line shell.

C# and F# on the Mac with Mono

Please note that this article is badly out of date since the release of .NET Core and Visual Studio for Mac. An updated article is in the planning stages. Mono is the open source .NET runtime for Windows, Linux, and OS X. It consists of the Mono runtime environment, libraries, and C# and F# compilers. Recently Mono has gained extra popularity due to Microsoft’s purchase of Xamarin, the makers of a cross-platform toolkit of the same name. Read more →

Semi-Autonomous, Programmable Drones Incoming

Drones, or Unmanned Aerial Vehicles (UAVs), be they quadcopters or other type of flyer, will become more “intelligent” as themselves or by forming swarms, as this TED Talk by Vijay Kumar at U. Penn shows. My interest in drones lies not in flying them myself live, because I’m a lousy pilot and don’t play games much anyway, but in making them follow a predetermined route and return back to the starting point – for example, surveying an object or estate, or even carrying cargo between waypoints.
