This Week in Tech

The importance of being Uncertain and other fun facts...

Welcome to our 50th blog post. We hope that the blog has at least made one useful contribution to your teaching, classroom and / or learners. This week's news tends towards the lighter side and there are a couple of fun things you can show your learners to put smiles on their faces.

Uncertainty rules!

The first item on the agenda is MIT engineers proving that you don't need GPS and precise knowledge of location to improve an autonomous drone's ability to avoid obstacles. Instead they allow the drone to keep what they call a 'nano map' in memory which the drone continually refers to. By comparing past images with the current image the drone can position itself relative to obstacles and take the appropriate evasive action.This is much closer to how we humans do things and reduces crash rates from 28% to 2%!

Weird Hardware Hack

Q: What do you get if you combine parts from a flatbed scanner, dot matrix printer and a hard drive, with some mechanical parts and a pencil?

A: The weird 'printer' below that uses a pencil to 'tap' out an image.

Useful? NO. Fascinating? Yes!


Robots continue their advance...

Wired has a story on how Boston Dynamic's Spot robot dog can now open doors (video below). Makes me think of the 'Metalhead' episode from Black Mirror season 4.

Or maybe not so much... The Winter Olympics provided the ideal opportunity for various robotics teams to show just how far robots have to go. The narrative is not English but the visuals are universally understandable.

5G and Wild Boars

More from the Winter Olympics. 5G is a specification that is only due to hit mainstream in 2020. South Korea has been using the technology (capable go 10 Gigabits data transmission speed) in various demonstrations throughout the Olympics. One of the uses is for automated defences against Wild Boars to keep them from invading competition tracks. TechCentral has the details.

Recycling old computers into art

Zayd Menck has built a model of Midtown Manhattan (New York) from old computer parts...


In other news:

    • The BBC reports that Bitcoin mining in Iceland is about to use more electricity than all the households in the country.
    • Meanwhile the SA Reserve bank wants to regulate Bitcoin in SA (MyBroadband).
    • Facebook lost 2.8 Million US users under 28 years old last year (Recode).
    • Facebook (again) is getting more intrusive by asking you to add lists to your wall... (Engadget).
    • Want to take better photographs? This AI will shock you into getting it right! (Hackaday)

And that's it for this week. Enjoy!

Humans can't own property - only corporations can

Chaos and absurdity seem to abound in world events and politics (local and international) at present, so it seems only fitting to take this blog's title from a standpoint held by big corporations abusing copyright protection law to protect physical products. That's not all though, there's plenty more absurdity to come. So strap in, buckle up and enjoy the ride!

If you had to guess from previous posts where the title of this weeks blog come from I'm sure that you'd eventually arrive at: John Deere. Boing Boing has the details.

Hacking news and absurdities:

  • Ransomware is being hidden inside attachments - to attachments. Details at Lifehacker.
  • Downloaded a 'guide' to a game from the Google Play store? You might be one of over 2 million people infected with malware from these trojan apps. Hacker News has the details.
  • Badly written Android apps leave ports open - and your device open to hacking. Hacker News.
  • Intel has a firmware hole that's been around since 2008. Ars Technica explains (technical).
  • HP notebooks have a pre-installed key logger in an audio driver. htxt.africa. If you have one of these, best you get it fixed.

Fake news Dept:

Birds. Small, beautiful, fascinating and deadly.

To airplanes, at least. Birds being sucked into the swirling vortex of a jet engine can break turbine blades and cause a catastrophic failure of the engine. Which can kill the plane and, in the consequent crash, probably most of the people on board. So birds are a problem - especially around airports, where they are likely to come into contact with planes and their engines.

Enter the Robot Falcon - a drone that looks and flies like a falcon and is designed to scare birds away from airfields! Check it out at Atlas Obscura.
