This Week in Tech
Facebook never seems to stop putting its foot in its mouth. They're in the news again this week because of, amongst other things, spreading fake news videos about the victims of the recent mass school shooting in the USA. China also features with a concept sure to appeal to at least some of your learners - namely gaming schools! Then there's a whole batch of other interesting tidbits - specifically an in depth article on how it is becoming more difficult to learn to program.
E-Sports - a career option?
E-Sports are a thing. There are competitions with significant prizes and even TV stations dedicated to covering people playing games such as StarCraft against each other. The Citizen has an interesting article on China's approach to the concept of learners playing games in school. Well worth a read...
|260 million people are already playing eSport games or watching competitions...|
the eSport industry will be worth $906 million in global revenues in 2018
China an example of future surveillance state?
Not really an article you can use in the classroom, but an interesting view of ways that the state can use technology to surveil its citizens. Engadget has the details.
Always Connected Windows - limits exposed
Remember a few posts back I mentioned the prospect of an 'Always Connected' Windows machine using ARM processors - and feared that it would have the same kind of limitations as the failed Windows RT project. Well, DigitalTrends has an article detailing these limitations that was briefly listed (and then pulled) by Microsoft. Spoiler: if you were expecting the full Windows experience then prepare to be disappointed.
YouTube, Facebook and Fake News
Recently 17 young people were killed in a school shooting in Florida. Or were they? Right wing gun freaks claim its all a hoax - and YouTube and Facebook spread their message... Business Insider has the details. Om Malik Explains why Facebook will never change this kind of behaviour.
This YouTube channel has a set of lessons on how computing theory that you could find very useful.
That's it! Hope it's useful.
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.
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.

And that's it for this week. Enjoy!
Welcome back. The news this week contained some interesting tidbits - the most awe inspiring of which was Elon Musk and SpaceX's successful launch of the Falcon Heavy rocket. Besides the rocket (whose 27 engines did literally shake the earth) there's nothing of earth shaking, overwhelming importance. Let's jump straight into it then...
The Falcons have landed.
Falcon Heavy, the most powerful rocket in operation today (and the most powerful since the Saturn V which took humanity to the moon) completed its test launch this week. Your learners might like to know (if they don't already) that there is now a cherry red sports car (with a space suit clad mannequin in the driver's seat) on its way to Mars!
More significant and beautiful and awe inspiring was the simultaneous landing of the two booster rockets at Cape Canaveral (these rockets had both been used before). The whole launch is worth watching just for this landing.
Of course, SpaceX's rockets are completely computer controlled and the precision of that landing would be impossible without IT.

Sim Swap hacks reaching the US
SIM Swapping is nothing new for South Africans. It has been part of our cyber crime landscape for yonks. Seems like that is not the case in America. Motherboard has an article on T-Mobile issuing warnings about the scam. They call it a 'phone number port out scam'. Sim Swap seems so much easier to understand...
Social media & the death of originality
The video below is a collage of people's travel photographs on Instagram. Read the article on Boing Boing to see what the photographer Oliver KMIA has to say about our obsession with photographing and posting. He also points out his video is a cliche - a copy of what others have done before...
The House IS the SPY
Gizmodo has a fascinating article that was intended to reveal how much as smart house spies on you - but ended up revealing a bigger problem with the technology...
It's just plain irritating!
South Africans need to improve their Cyber Manners
htxt.africa has an article detailing Microsoft report showing how badly South Africans behave online.
As teachers we need to make sure our learners, friends & family know better and tech others to behave better!
US Navy buys first big Laser Canon
Motherboard has the details.
Smartphones used in fighting crime in New York City
The headline of this Digital Trends article is about how New York cops are switching from Windows Lumia phones to iPhones. Read past that for some insight on how smartphones are actually used by the police.
3D Printing in full colour
If you have $50 000 - $100 000 you can get one of HPs new full colour 3D Printers. It may be unaffordable now, but is shows what kind of future is heading our way - fast!
That's it for this week. Enjoy & tech well.
This week has a lot of news, in many mixed areas of interest. No space for an into - just jump in and enjoy!
Amazon Go - 'Queue free shopping experience'
I'm not sure how it slipped past, but the last post was meant to include the new Amazon Go - 'Queue free shopping experience' shop that has just opened in Seattle.
Unfortunately there's a queue to get in...
RFID was always touted as the way that shoppers would be able to pile goods in their shopping cart and then simply walk out the shop and have the sensors automatically read the price of their goods and bill them without having to stand in a queue. That dream has not (yet) materialised - and is vulnerable to people doing things like removing the RFID tag from goods, swapping tags on expensive goods for cheaper ones, etc.
Amazon thinks they have a solution. A shop where you can only enter by having your smartphone scanned, and then being watched by many, many, many cameras that track what you put into your basket so the system bills your credit card when you walk out. Several news outlets have tried shoplifting (and failed - here's Ars Technica's report on their attempt) but some youtubers have claimed success.
There are some obvious cheats - shelves are designed to try to ensure that you can't put items back in the wrong place (to make it easier for the computers to identify them)
Here's Amazon's info page.
Think of the thousands of cashier jobs that will be lost if this technology proves a success (Forbes has).
UK Airport Security takes romance into consideration.
Digital Trends has the scoop - an amusing read.
Contactless (NFC) cards and security in SA
MyBroadband has an article where banks tout the safety of the system. No research, just spokespeople...
The value of Data
MyBroadband has an article on how Vodacom makes R2 BILLION per month on data alone.
Keeping fit... leaks info on military bases
Making data sharing an opt-out feature is always a bad idea. Sure, it lets companies be confident that they will be able to slurp up data from users who don't think about the fact that they are being tracked - or are too lazy (or ignorant) to turn off data sharing for the app. But even 'anonymised' data has its risks. This week it emerged that Strava, a fitness tracking service, has inadvertently spilled the beans on military and other secret installations around the world.
Users of products such as fitbit go out for a run. Their route is tracked. The data is 'cleaned' and anonymised and uploaded. Strava thought it was a great idea to aggregate the data and display it on a global map so that fitness buffs could find popular places to run and exercise. Problem is, some of those routes are run by military personnel inside military bases... Read it at Hackaday and Nine.Com.au (some good graphics and explanations of consequences here).
More Privacy - G.D.P.R. and how tech companies are scrambling to prepare for it
This one is important. Europe has a new set of rules to protect privacy (General Data Protection Regulation) which come into effect on 25 May 2018. If your internet service breaches these rules then your company can be fined up to 4% of your yearly income. As you can imagine, big companies are working hard to make sure that they comply.
Often they take the easy way out - excluding privacy busting features of their products from the European market.
More Amazon - patent granted for wristband to track workers
Gizmodo has an article on a patent that has just been granted to Amazon. The patent is for a bracelet that workers will wear - and which will allow their hand movements to be tracked. This will allow the system to see if you are slacking off - or making mistakes. As the article points out, this is only a patent (at the moment) and probably serves as a way to treat human workers more like robots until robotics advances enough to replace them.
Cartoonist predicted the problem of intrusive cell phones - more than 100 years ago!

Bitcoin miner uses oil to cool his rig
Submerging your computer in oil is an effective (if messy) way to keep it cool (oil does not conduct electricity but is good at dispersing heat). The really interesting thing about the article from Motherboard is some of the statistics it reveals about the cost of mining bitcoin. If you have been carried away by the soaring price of Bitcoin in the last short while, these stats will be of particular interest to you. Summarised, they are:
Bitcoin and TAX
If you have made some money from Bitcoin (or know someone who has) then read this. Hope you put aside the tax man's share...
MinION - Palm sized DNA Sequencer
It took a group of scientists 13 years of work and cost $3 Billion to map the human genome. Supercomputers and distributed computing techniques were needed to do the work. Now the MinION, the pocket sized device in the video below connects to your laptop or desktop using USB 3 (and is powered by UB) and can map a genome for as little as $1 000.
AR lets doctors see through your skin
Augmented Reality is so much more useful than Pokemon Go would make you think... Digital Trends has the low down on how researchers are displaying your insides on your outside to help doctors...
How much money (profit) do big companies make - per second?
Check out this interactive graphic to find out. Spoiler alert: Disney only makes $297 per second. Facebook makes $323 per second. Apple makes $1 445 per second!
What's so special about this movie?
The entire, feature length movie was shot on iPhone. No more excuses - you have the same camera tech in your pocket. Now go out and make a movie! More info available here at htxt.africa.
Paying for popularity
The New York Times has a great article on a company called Devumi that sells followers, tweets, retweets, etc for people who need to boost their metrics to prove their popularity. Some of the followers they sell are automated bots based on real people - the product of identity theft.
|Devumi has more than 200,000 customers, including reality television stars, professional athletes, comedians, TED speakers, pastors and models. ...|
Devumi offers Twitter followers, views on YouTube, plays on SoundCloud, the music-hosting site, and endorsements on LinkedIn, the professional-networking site.
