Weekly Head Voices #107: Balance.

That’s how the African sun sets in Mpumalanga.

… and this is more or less what it looks like when a cheetah decides to grace you with its presence. We had it all to ourselves (this is quite unusual in the Kruger National Park with an animal of this level of celebrity) and were able to follow it until it wandered further away from the road, probably on the lookout for some dinner.

Dolphins on the R44

On Sunday, April 10, 2016, as if the day was not already perfect enough, we were super fortunate to see a pod of dolphins speeding along in the sea right next to the R44 coastal road.

The sight was so spectacular, that we could not spare a second to get our cameras out, so you’re going to have to be satisfied with this photo of me and GOU #1 admiring the pod as they swam out of sight.

Weekly Head Voices #105: There will be tears.

Congratulations, you have successfully completed the week of Monday February 8 to Sunday February 14, 2016!

About 4 seconds after posting previous edition WHV #104 to Facebook with the “When you’re a vegan and haven’t told anyone in 10 minutes” meme image included, friend Ivo T. zinged me with this reply:

So much truth. I have been put back in my place. Sorry vegans. Sorry MBA students. Not sorry Ayn Randers.

Weekly Head Voices #104: Let me update you.

This post is about things that I noticed in the week of Monday February 1 to Sunday February 7, 2016.

I dug up an email I wrote to Alex Stepanov and Meng Lee, authors of the C++ Standard Template Library on Monday August 3, 1998, to ask them if they would have written a matrix template, if they would have derived it from the vector template. Stepanov answered, the next day (!), that he had never found much use for inheritance. In those days, nerd celebrities mailed you back. Also, poor old C++ inheritance…

Weekly Head Voices #103: Chips!

I thought that I had nothing for the two weeks from Monday January 18 to Sunday January 31, 2016, but my notes begged to differ. They suggested the following items for your reading, listening and viewing pleasure:

Party trick

If you’re like me, you stop two to three chips short of finishing the packet so that you can explain to your conscience that you didn’t finish the whole thing. However, once or twice in my life, I’ve been faced with the terrifying conundrum of a partially finished packet of chips, but no way to seal the packet for later utilisation. Readers, agonise no more! Learn from this animated demonstration:

Fix the unusable window resize border in Gnome Flashback Metacity on Ubuntu

On Ubuntu I mostly use Gnome Flashback with Metacity, along with the brilliant Synapse app starter / file finder. I do this in spite of having a beefy NVIDIA GPU in this Core i7 workstation, because the OpenGL compositing on this 2560×1440 display makes video conferencing really slow, and because I do OpenGL development and need to have maximum performance for the app I’m working on.

However, it irritated me to no end that the window borders were so thin that I was not able to grab them for a resize. Adding insult to injury, there were only the four standard themes in Settings | Appearance, namely Adwaita, Ambiance, Radiance and High Contrast, none of which has usable borders.

Weekly Head Voices #102: High on life.

The week of Monday January 11 to Sunday January 17, 2016 got off to a brilliant start with a business lunch at Bodega, a restaurant that finds itself on the Dornier Wine Estate. The view looked something like this:

… and the company was suitably awesome. (This is not the first time that Bodega makes its appearance on this blog, or in the blog-free suburbs of my social calendar. The company might be different every time, but so far its level of awesomeness has been quite consistent.)

Closure expressions in Swift

Swift is a new high-performance compiled language designed by Apple. I’ve had some experience using it for an IOS development project, but the language is open source and is already available for Linux.

Some of you are probably able to appreciate the irony of me writing a blog post about Apple’s new programming language Swift, but here we are. :) I am, grudgingly, really impressed by Apple’s good work.

In this post I’m going to chat about closure expression syntax, in the process showing you IBM’s Swift Sandbox, an online tool for experimenting with Swift.
