Study Opportunities' Blog
With the new year comes a new change to the format and contents of the blog. We'll try to add resources and tools each week as well as a news summary. This week we take a look at something that can increase the amount of fun, competition, participation and learning experienced by your learners. We're talking about online testing / quizzing.

There are many testing and quizzing tools out there. Some are free and others are subscription based. Some allow for a whole range of question types whilst others are basically multiple-choice on steroids.
This week we are going to take a look at one that allows for a competitive class quiz scenario with a live scoreboard that you can project so that your learners can see who is winning. The tool is:
Here are some videos that you can look at to find out more.
If you like the tool, create some quizzes and want to share them you can add them for people to find using the comments below.
Finally: All about AWS
It finally happened. It was only a matter of time. A self-driving car has collided with and killed a pedestrian. The car belonged to Uber and Uber has pulled all of its self-driving cars off the road whilst the incident is being investigated.
Motherboard has a fascinating article on the hard decisions that have to be made when planning and coding the decisions that a self driving car has to make regarding safety and who gets hurt / who dies. This is a great read - and a really great topic for a class discussion / debate. This is an issue which is going to feature prominently in your learner's lives.
You can read about the incident itself here.
The Facebook drama continues...
Facebook is dealing with a massive backlash from the Cambridge Analytica data scandal mentioned in last week's blog. There is a concerted DeleteFacebook campaign complete with hashtag and all. Elon Musk removed the Tesla and SpaceX presence from Facebook. Vox has an interesting article that details 'The Case against Facebook' - taking it far beyond data breaches. CNN AMP points out that no matter how much he promises and how much he wants to, Zuckerberg cannot control or fix Facebook (and he knows it). It's become a monster beyond its creator's control.
It's so bad even their own investors are suing them.
Meanwhile Boing Boing says : Facebook, ShmaisBook --- you should see what your ISP is doing with your data!
This week the SA Post Office web presence did not exist - because someone did not pay the R125 domain renewal fee....!!!!
What's really special about Siren is that she is rendered in real time from a motion captured human using the Unreal gaming engine - and a PC with multiple graphics cards.
The video below shows a fish-man (actually Andy Serkis) created with the same technology.
This shows where 3D graphics and video are headed. Soon you will really not be able to distinguish virtual from reality.
World's smallest computer.
The older ones amongst you (those who saw the first PCs in the 90's) pay attention. That clunking desktop computer that you paid an arm and a leg for.. well it is now the size of a grain of salt and cost $0.20. IBM just announced the product and sees it as the ideal way to embed computing power in everything.
Mashable has the details.
That's it for this week. Holidays soon!
Two HUGE hacks dominate the news this week.
KRACK - patch your WiFi fast!
KRACK affects WiFi at its lowest level - the WPA2 password security that encrypts and protects communication on the network. The bad news is that this security has been cracked, making all communication on the affected network vulnerable. The good news is that most new OS's have patches out there or patches will be coming in the near future. Fixes for routers may take time, but as long as your OS is fixed you should be safe, so make sure you install those updates as soon as they become available! Ars Technica explains how the KRACK exploit works.
SA Database leak - 60 Million affected - and that includes YOU!
This one is a bit more tricky. A database of more than 60 Million South Africans' information has been leaked online - the source of the leak is yet to be determined (read it at My Broadband). The bad news: The leak contains Names, full ID numbers, email addresses, contact details, age, marital status and income estimates. It is a perfect source for identity thieves. The database contains records of almost anyone involved in economic activity between 1990 and 2015. This includes people who have passed away in that time - hence the fact that the leak is larger than our current population!
The good news: There is none. The information is out there and you can't get it back. Watch out for any signs of Identity Theft... You can check if your data is in the leak - go to Have I Been Pwned, enter your email and hold your breath...
What can you do? Not much. Check your credit status now and regularly to see if someone has stolen your identity and obtained credit in your name. Then try to get the credit cancelled / revoked.
Backup and data recovery
The Hacker News has an interesting article on how a ransomware attack took down an American city for four days. Their point is to show the cost of the breach - I think it is a good illustration of the importance of doing backup right...
Microwaves make 40tb hard drive possible
Western Digital has announced that a new microwave technology will enable 40tb hard drives by 2025. Engadget has the details.
LED foils copyright breaking photography
This is an interesting story of how pulsing LED lights can ruin the photos taken by digital cameras and prevent them being used to take copyright breaking images in museums, etc. Digital Trends has the story.
Ever wondered how your smart device (or home speaker, or smart TV) is able to tell when you want to give it a command by using its own special trigger phrase? Apple has published a full explanation of how its "Hey Siri" feature works. As complex as the process is, the astonishing thing is that it takes place all the time without having a noticeable effect on battery life. NB: The same explanation cannot be applied to other devices (all companies use their own technology).
The Uncanny Valley
What is it? This video explains perfectly!
The same people have a well reasoned explanation of why to be sceptical (as I am) of the VR hype...
That's it for this week....
