The FPB (Film and Publications Board) which so recently and unreasonably overreached itself by giving the film Inxeba: The Wound a pornographic "X" rating, is one step close to trying to censor the internet.
MyBroadband has the details here and here. This gives you a great opportunity to discuss and debate the issue of censorship in general, its dangers and, more importantly, the practical feasibility of enforcing this law.
The Human Error dept.
On 7 March all Occulus Rift VR headsets worldwide stopped working. Not because of a bug or a software problem, but because a security certificate was not renewed. MyBroadband has the details.
This Motherboard writer found himself stuck without a heater in the latest cold blitz in the USA. His solution? Fire up his cryptocurrency mining rig. His article explains how effective it was - and the upshot in terms of cost. A short but entertaining read.
Alexa's Creepy Laugh.
Just read the BuzzFeed article. If it happened to me I'd probably also be creeped out.
The Yellow Pages finally bends the knee
The Yellow Pages. Remember them? That fat book of (obviously) yellow pages containing business listings and advertising for the landline, pre-internet area. Well, it still exists and is going digital. MyBroadband has the details.
What to do when your ISP over-promises and under-delivers
Your ISP sells you a 20 mbps line. You never get to experience that speed. In fact, you are lucky when you get 10 mbps. What to do? In SA, unfortunately, not much. The UK govt has seen the light and has passed a bill which will allow users to simply tear up their contract and move on without penalties. Cool. Engadget has the details.
Deepfakes. AI generated face-transposing videos.
There has been a lot of buzz about the problem of DeepFakes - a technology which has been used to create fake pornographic videos of celebrities by putting their faces on the bodies of porn stars in porn videos. This New York Times article takes a deeper look at the tech and how it works - and foresees the fake news problem becoming worse with a looming increase of fake videos.
More on the fake people in video scene...
If you saw the original Blade Runner movie and the new sequel then you would have noticed the appearance in the new movie of a character from the old - completely unchanged. Boing Boing has an article showing how this was done.
Two articles on News, Fake News and reading from the New York Times.
Both are worth reading.
The Guardian has an article in a similar vein detailing MIT research on why fake spreads faster than true on Twitter.
DigitalTrends "What is" series
Finally: China's first space station due to crash back to Earth
This will happen somewhere around the end of this month. No one knows exactly where or when. Engadget has the details.
That's it for this week. Ciao.
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....
It has been a relatively quiet week (if you exclude product launches) in general tech news. So this week's blog is equally short - but it does contain one or two interesting snippets...
We know that storage keeps getting smaller, faster, cheaper. BUT, this typically relates to the 'working storage' that we use all the time whilst our devices are active. Backup storage needs RELIABILITY above all other factors as its main characteristic. Tapes, Hard drives, optical media... they all fall short when it comes to long term archiving and storage of data. The material itself degrades, the hardware and software used to read the media becomes obsolete and so, ironically, our age of data collection and accessibility might in the long term, possibly end up with fewer records than the written pages of the Middle Ages!
One of the efforts aimed at solving this problem is aimed at figuring out how to store data using DNA. Yep, that same stuff that holds the genetic encoding that makes you 'YOU'.
This week in the news saw scientists encode complete jazz songs onto DNA - Digital Trends has the article here. The company responsible - Twist BioScience - has and interesting blog explaining what they see as the need for and the potential of DNA storage here.
The New York Times has a short 'Q&A' style article explaining what Bitcoin is and how it works. Worth a read if you don't understand cryptocurrencies...
The video says it all....
That's it for this week.
This week's news contains two significant robot announcements that point the way to a future where robots take over and humans have very little work to do. What existed only in the imaginations of comic book and Sci Fi authors in the 1960's is lowly becoming reality as our technology starts to catch up with our dreams. What is making this robot revolution possible? Small, low powered, reliable sensors (including GPS); powerful SoCs (System on a Chip - where the whole computer system is on a single chip); plentiful, fast, reliable and cheap memory and storage and major advances in AI algorithms....
Our robotic future
To the self-driving cars that seem to be just over the horizon we can now add robots that can farm by themselves - and carry out dental surgery without a human's guiding hand...
Hands Free Hectare is a project at Harper Adams University which just successfully proved that robots can plant and harvest a field without any human intervention. The robots in question were installed into old farming equipment (tractors, harvesters, etc.). During the entire process - from planting to harvest - humans were not allowed into the hectare sized field. The result? 4.5 tons of Barley!
And in China (where there is apparently a shortage of dentists) a robot installed two dental implants in a patient (humans are still required to change drill bits etc, but the precise, in-mouth work was carried out by the robot autonomously. On top of that, the implants were 3D printed! 3Dprint.com has more.
These are two great and interesting examples of ICT 'disrupting' the world as we know it and possibly increasing productivity whilst causing job losses for humans. It used to be that only factory style work (precise and very repetitive involving no ability to sense the world or make decisions) was the target for robotic replacement. Now any job is fair game...
Mining vs Advertising
Much of the web (and most of the 'free' apps and services we use) is 'powered' by advertising. The problem is, advertising is becoming over saturated and people are becoming suspicious and resentful of the 'tracking' that advertisers do. This week we saw proof that companies are investigating alternative sources of income. One of these alternative sources of income is 'mining' cryptocurrency. To 'mine' a bitcoin or ether or any other type of cryptocurrency you need to perform some intense calculations to solve complex mathematical problems. To make money by mining cryptocurrency you need expensive computer hardware running at full capacity - which uses a lot of electricity.
So why not get other people's computers to do the mining for you using a type of distributed computing?
That's exactly what The Pirate Bay (something you could expect of them) and video streaming site Showtime (a big surprise) did this week. They embedded scripts in their web pages that made your computer do cryptocurrency mining when you visited them. Your computer did the work, you got the electricity bill and they earned cryptocurrency. All without asking your permission. The Guardian has the details.
Tinder is a dating app. Like most modern apps it collects data about you to 'improve its performance'. We all know this. What might surprise you is how much data it collects. A journalist who used Tinder for 4 years of using Tinder requested that Tinder supply her with the data it collected. European data laws allowed her to do this and eventually Tinder complied - the result adds up to 800 pages of collected data. Data from Tinder, Facebook and Instagram had been collected. All the places she was when she used the app. The online conversations she had with people she matched up with.
|“Tinder knows much more about you when studying your behaviour on the app. It knows how often you connect and at which times; the percentage of white men, black men, Asian men you have matched; which kinds of people are interested in you; which words you use the most; how much time people spend on your picture before swiping you, and so on. Personal data is the fuel of the economy. Consumers’ data is being traded and transacted for the purpose of advertising.”|
Alessandro Acquisti - from "I asked Tinder for my data. It sent me 800 pages of my deepest, darkest secrets" in The Guardian, 26 Sept 2017.
The extent of data collected by Tinder is astonishing - but is nothing compared to what Google knows about you. Remember - the connected world is NOT a private place.
Read the article at The Guardian (worth the time).
Tapes are back!
No, not your 70's, 80's and 90's mix cassettes - no matter what the Guardians of the Galaxy franchise would have you believe. We are talking tape based data backups. The fact is, disk based backups are vulnerable to hackers. Tapes are slower, not permanently online and more cumbersome - but their major advantage is that they are secure. You need physical access to mess with their data. That's why many companies are looking to use tapes as a secondary, more secure type of backup. Read it at Marketwatch.com. This ties in with spies and security agencies going back to typewriters, paper and filing cabinets because hackers make data security a joke!
That's it for this week. Happy teaching...
