Why Your First Course in Topology Will Probably Be Disappointing




My professor had one of these stickers right on his office door. It’s a classic and simple topology joke, playing off the fact that topology is often regarded as the study of “nice” continuous deformations, such as stretching, shrinking, and twisting. The…

SkyDive, as you can guess by the name, is a 1st/3rd person wingsuit game, where you throw yourself down a mountainside and seek out extreme thrills, while trying to avoid broken bones.

like our other recently featured wingsuit game - Wingsuitflyer - it’s an adrenaline fuelled extreme sports game about flying/falling down a mountain face first.  Although in SkyDive instead of getting points by skimming near the ground, you get points by doing tricks in mid air while trying not to fail horribly and smash into the ground.

As well as pretty visuals and rapid descents, the game also has an excellent soundtrack and a fun 2 player split-screen mode.   Unfortunately, it looks like development had halted on SkyDive, which is a shame as it’s a blast to play, full of aerial acrobatics, beautiful vistas and a touch of danger.

A Urine Powered Generator. An amazing accomplishment by four brilliant girls. The girls are are Duro-Aina Adebola (14), Akindele Abiola (14), Faleke Oluwatoyin (14) and Bello Eniola (15).
  • 1 Liter of urine gives you 6 hours of electricity.

  • The system works like this:

    • Urine is put into an electrolytic cell, which separates out the hydrogen.
    • The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder.
    • The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas.
    • This purified hydrogen gas is pushed into the generator.

This is amazing. Give them a billion dollars right now. They may have just saved the planet. 

Also, the technology involved in this generator can be produced really cheaply, and none of the components are patented. That removes major obstacles to production and deployment, and I’m certain that these girls were very conscious of that during development.

SightLine is an adventure puzzle game which uses line of sight as a core gameplay mechanic, with items and scenery dramatically changing when you’re not looking.  An all-knowing narrator helps guide you through the disorientating, somewhat creepy game, with visual trickery reminiscent of that seen in Antichamber.

There is a Prototype and a Playground available to download, the playground is a small test arena, while the Prototype has more intricate puzzle elements and takes you through a variety of destinations, such as a floating mountain town, a forest or just nothingness.  One thing is prevalent throughout both builds though, whether you’re in a dangerous situation or not, it can all change depending on where you look and your perspective of it.

SightLine is a thoroughly disorientating, perplexing, wonderful experience that full of surprises and clever touches.  Also, if you’re lucky enough to have an Oculus Rift it’s a must-play (though it’s still works well on a normal screen).

This might be really stupid but

what about having code that transforms the Debug-based Haskell code into Debugless Haskell code? Alternatively, make a Monad that takes a type and a monad as arguments and can toggle whether…

You know there’s Debug.Trace right?
