This Week in Tech

Gif Attack!

Deadly pictures. Farmers becoming hackers. SSDs that can double as RAM. Lasers protecting Salmon. A physical key for safety in the digital world.... This week's news is a mixed batch - most of which sounds and feels a little incredible and sci-fi. Enough credible news outlets have reported on the topics to be reasonably sure that none of it is 'fake news' ;-) [and now I have just used an emoji in a blog post, something I never thought I'd ever do!]. Anyhow, there's a lot in this post that will make you shake your head in disbelief and which you can use to amaze and astound your learners.

Gif Attack.

Gif. The image format that allows for animated images to be shared on the web and through social media. The image format that has been intentionally used to physically attack a human being. You see, people who suffer from Epilepsy can have a seizure triggered by flashing lights (that's why there are epilepsy warnings for some video games, movies,etc.). So a Trump supporter (who else would be that dumb and malicious) designed a Gif that would trigger a seizure and then sent it to a reporter that they felt was criticising the president too much. He also made his intentions clear by putting “You deserve a seizure for your post” below the image. A Texas jury has just ruled that a Gif image can be considered a deadly weapon. Read the fascinating story at here and here Digital Trends. The person responsible tried to hide his tracks by creating and using a fake twitter account but has been traced and identified.

American farmers pwn their farming equipment.

No, pwn (pronounced 'pone') is not a typo. Well, it actually was originally one when some unknown hacker typed 'pwn' instead of 'own' when describing taking over someone's computer. This 'leetspeak' (language used by the 'elite', the hacking community) term is what American farmers are having to do to their Tractors, Combine Harvesters, and other computerised farming equipment, especially those made by John Deere. A fascinating article on Motherboard describes why and how they are doing this.

"What you've got is technicians running around here with cracked Ukrainian John Deere software that they bought off the black market"

Save the Salmon - with lasers

Sea Lice. Parasites that flourish in the nutrient rich environment of a densely packed fish farm. A real problem for fish farmers. Enter.... an underwater drone armed with lasers that shoots to kill! Check out the article on Digital Trends. Or just watch the video below.


Storage or Memory? Both!

The line between storage and memory is being blurred by a new Intel product - the Octane SSD. Ars Technica has a technical but interesting article that is worth a read, more for you to be informed so that you can say to your learners that maybe in the future Ram and Storage will be the same thing. Basically a normal SSD is 10 000 times slower to respond to a read or write request than RAM is. The new Octane SSD is only 10 times slower than RAM! This means that you can choose to use it either as RAM or storage, depending on the needs of the moment. NB: A very exciting and interesting technology that could have a huge impact on hardware of the future! Of course, like most new technology, it is insanely expensive now - expect to pay around R20 000 for less as 375 Gb unit.

The poisoned wine problem

Brian Brushwood presents this video (from his 'Scam School' Youtube Channel) which you can use to have some fun with your learners when doing binary numbers.


A battery that powers chips whilst cooling them

This is a loooooong way off, but holds some very exciting potential. I'm not going to repeat the article so just head over to Engadget and read it there.

Fido. The physical key to your digital security.

This one is also a long way off, but is a potential solution to the 'hackers keep stealing usernames and passwords' problem. Read it at My Broadband. In the meanwhile make sure your learners understand the need for (and use) two factor authentication on any of the sites and services they use that offer it.

Which is the Safest browser?

Google's Chrome remains uncracked at 2017 hacking contest.

PC Building Simulator Game

Your learners might have fun with this. And they can learn something without destroying expensive hardware. Download the software (still in beta) here and check out the video below.


Fake news corner:

  • Social media wrongly identifies the London attacker
  • The Programme for International Student Assessment (PISA) - the organisation that ranks countries student in academic ability (if you see headlines telling you that, for example, 'Singapore students best at math in the world' then the research and testing has been done by PISA) - currently tests and ranks students in maths, science and language. They are planning to add a test for students ability to identify fake news. Read about it from the BBC.

Other News for the week

That's it for this week. Hope you find it all as amazing, astonishing and interesting as I do. Happy teaching.
