This Week in Tech
Remember that whole saga of Apple vs the FBI when Apple refused to create a back door for the FBI to investigate a terrorists phone? Apple said that it was too dangerous and would make iOS vulnerable to hackers. The FBI said something like 'but you can trust us, we are a powerful government agency, we will protect the backdoor and keep it safe and no one else will ever get to use it - especially not hackers....' Apple stuck to their guns and the matter was never tested in court because the FBI withdrew their case and found an alternative solution to their problem.
Turns out Apple was very right though. A couple of weeks ago we reported on US government hacking tools and secrets being exposed by a hacker group calling itself the Shadow Brokers - and published on Wikileaks. That leak led to the biggest flood of ransomware infections in history. Computers across the globe became inaccessible - their data encrypted and unavailable. Ransoms of $300 - $600 were demanded. Here are some very important facts about the infection:
Wanna Cry infected hundreds of thousands of computers in over 100 countries world wide. It crippled businesses, government offices, health care (especially the NHS in the UK) and private computers indiscriminately.
The biggest lesson though is that machines with the latest version of the OS and up-to-date patches were pretty much safe from the attack.

MP3 is dead - NOT!
News articles this week tried to scare people into believing that MP3 as a music format is dead. Why? Well, basically the Fraunhofer institute that created MP3 is no longer licensing the format. Because their patents have expired. Which means that the format essentially moves into the public domain and is free for developers to write encoders and decoders for without having to pay royalties.
The articles suggested people use other formats such as AAC - which are, co-incedentally, still under patent and require royalty payments. These formats are newer and (slightly) better than MP3. I was just gearing up to explain the nonsense in detail when I came across this article by Marco Arment - who did it all for me so I don't have to!
The Working Dead - IT jobs in review
As IT and CAT teachers we have a vested interest in extolling the job market for IT savvy workers. InfoWorld has an excellent article on the evolution and turnover of IT related jobs and just how tricky the IT job market can be. Well worth a read so that you can talk in an informed manner with your learners on the topic.
Fake News corner:
You might wonder why I did not report on the supposed 'Blue Whale' suicide game last week. It's simple: what information was out there seemed sketchy, anecdotal and unreliable. It seemed like a sensationalist story, the kind that proliferates on Facebook. Here's htxt.africa doing some serious research and vindicating my opinion of the story and not giving it any kind of credence.
