Preface As a part of learning the Ruby programming language, while I continue the development of my Rails app (which I might go through in another series of posts), I thought it would neat to port my flagship computer game: Tokoton Shooter, which is a 2D, vertical shooter game that I created a long time […]
Method overloading allows a class to have two or more methods having same name. But there are some conditions applied if you overload a method. Let’s discuss on then. First of all we should know “ Why do we use method overloading in Java?” . Suppose we have to perform addition of given number but there […]
Aurora is back!
Last night the aurora came back for a brief visit. The light show was slow to get going but for a brief five minutes the sky lit up and sent purple and green pillars reaching high up towards the stars.
Charged particles from a coronal hole were forecast to reach the Earth yesterday and sure enough, once it got dark (around 9pm now that the clocks have moved to British Summer Time) my camera picked up a weak auroral arc. I’d headed out to my usual spot, up a hill and less than 15 minutes from my house. Aurorawatch UK had issued a red alert, the first since October 2016, so I was hopeful for a good light show.

When I was a teenager, I toyed with programming but didn’t get serious with it until I decided I wanted to get into graphic design. I found out that you don’t have to write HTML yourself, you can use programming to do it for you!
But I never stopped tinkering with hardware and systems. I used Linux and BSD on my desktop for years, built my LAMP stacks from source, and simulated the server environment when I couldn’t – when I used windows for work, and when I eventually adopted Apple as my primary platform, I first started with cross-compiled versions of the components, and eventually got into virtualization.

“We have a president who was elected not by popular vote, but by electoral college. And, the history of the electoral college is intimately tied to slavery and slave-owning states and is there in part to give more sway to states that had large populations of slaves who couldn’t vote.”
Installing Rakudo on Linux can be a dissapointment. Either from compiling from source, or install the old ‘rakudo’ package from our Linux distribution repository.
nxadm from Github has packaged the recent if not the most latest Rakudo Linux natives packages for Debian/Ubuntu and RPM based system (centos/fedora/opensuse).
