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!
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.

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.
If you are still using Flash, it's time to stop!
Flash is hacked again with another zero day vulnerability out in the wild. The Hacker News has the details.
That's it for this week....
Social interaction has always (in my mind) been humanities Achilles' Heel. It is in this area where our insecurities and fears are most exposed - and where our need to dominate and profit often rise above our more redeeming characteristics. The rise of mobile, always on, always connected computing has gone hand in hand with the rise of mega-companies that are little more than symbiotic parasites - they ostensibly offer 'free' services that add value to our lives yet - leech like - drain much of the good and decent and substantive from our lives and social interactions. It would seem as if there is no low they will not stoop to in order to maximise their own profits.
In recent weeks we have seen these giant corporations scrambling to explain how and why they sold adverts that influenced the American election; how and why they publish and promote fake news; how and why it is OK for the American President to spout divisive, bullying hate speech on their platform... I find myself viscerally sickened and repulsed by it all.
And yet their quest to inveigle themselves into our lives is ever more persistent, determined --- and creepy. Two stories on Gizmodo this week particularly creeped me out:
Both stories deal with PYMK (People You May Know). Facebook wants you to make 'friends'. Their thinking (and research) is that the more friends you have, the more you will interact with their site (and the more money they will make from you). So they keep on suggesting people for you to connect with and be friends with. How they find these people is a closely guarded algorithmic secret (after all, other companies want you to connect to people using their network so that they can make money from you) and no one outside of Facebook really knows how it works.
PYMK uses '100 signals' to work out who to connect you to. Facebook refuses to say what these signals are. They deny that they use data bought from third parties or location data / location tracking in this mysterious algorithm. Yet they only vaguely describe around five of these 100 signals.
Both the articles describe extremely creepy connections that Facebook has made between users - connections that should not be possible.
Should any company have this kind of invasive power that they can wield at their own discretion without our having any recourse to prevent them?
The Reed Dance and social media
Facebook and Google and most other social media tries to block and censor nudity. But what if being bare breasted is part of your culture?
The Mail and Guardian has an article on how local girls protest their bare-breasted photos from the Reed Dance being deleted from social media....
In case you missed it, Microsoft has discontinued support for Office 2007 (upgrade if you haven't already) and says that Windows 10 Mobile (and physical phones) is no longer a priority. The mobile space really belongs to Apple's iOS and Google's Android.
Kaspersky - Anti-Virus or Hacking tool?
If you use Windows then going without anti-virus software is like going into space without a spacesuit. It feels kinda suicidal. Of course, the fact that everyone needs anti-virus to protect themselves from the baddies who want to hack and steal data means that, well, the AV programs themselves are the perfect way to hack...
In the news this week is a complicated story of how Israeli intelligence hacked into Kaspersky AV to find proof that the Russians had hacked the AV software so that it would steal American spies' secrets. Sounds more complicated than a badly written Hollywood tech-spy thriller? Probably - but it is true nonetheless. Read it at Ars Technica (and many other places).
Technology and the future
MIT Technology Review has an interesting article on predicting the future of AI (and technology). It does a good job of explaining the limits of AI in its current forms (including the 'machine learning' that is a buzz concept today). Excellent, thoughtful and worth a read.
|We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run.|

A robotic massage
Digital Trends has an article on a massaging robot that has just started work in Singapore.
That's it for this week. Enjoy.
Welcome back after the Easter break. In this blog we'll summarise the news from the holidays, and warn that the next post will only be on 6 May as the author will be away. Happy catching up!
Mastercard test fingerprints in SA
Soon forgetting your PIN / protecting your PIN might not be so important anymore. Mastercard has been trialling a card that includes a fingerprint reader in the card in conjunction with ABSA and Pick n Pay. Many articles from all over. This one from BizNews.
All is not as it seems
Our learners live in a world where they are often bombarded by images of a 'fake perfect' culture. People pose, pimp, preen, ensure the light and camera angle are just so and create that all important 'perfect' image for posting on instafacebooktwitter. These girls at Hello Giggles show the difference between their posts and what they look like most of the time.
Might be worth a discussion about perception, the need to appear perfect and reality....
Bug in Firefox, Chrome and Opera makes phishing almost impossible to detect
This one is a bit technical, but bear with me... The WWW doesn't use ASCII. Instead it prefers utf-8 a unicode character encoding that helps make it easy for browsers to display other languages and symbols. This makes it possible for the web address https://www.xn--80ak6aa92e.com/ to be displayed as apple.com in your browser. A problem for detecting phishing, because one of the first things to do is check that the name in the browser looks correct. Read more at Hackaday.
One fingerprint to rule them all
Mastercard might be too late with its fingerprint reading bank / credit card. Those pesky researchers are at it again, creating not one but a set of 'master fingerprints' that act like skleleton keys and make breaking into digital biometric fingerprint security possible. Check out the article at Digital Trends.
Facebook and murder
So a guy has issues with his girlfriend. He thinks the best way to get her attention is to walk up to a stranger, get them to say his girlfriend's name, shoot them in the head, record it all on video and then post the video to Facebook. Where it remained for three hours before Facebook took it down, despite the video being reported. Discuss.
Learn to think like a computer
An interesting piece from the New York Times on computational thinking.
Germany to parents: 'split on your kid's piracy!'
OK, so its basically a 'tell us who did it or the person paying for the internet connection pays the fine' scenario. So German parents will have to cough up for underage children but will have to choose between splitting on their adult kids piracy activities or paying the fine themselves
