Communication

Whatsapp for you PC

Friday, February 13th, 2015

whatsappMany of us practically break out in hives if we’re outside the cellphone or WiFi reception range, while others are at their happiest in the middle of nowhere with no cellphone tower in sight. If you fall into the first category, you’re probably a devoted WhatsApp user.

The good news is that, from the end of January, WhatsApp will not only be limited to your phone, but also on your tablet or PC. Whatsapp Web gives users the convenience of sending and receiving messages via a website.

Your chats will be automatically synchronised between your phone and PC. The only limitation at this stage is Google Chrome as prerequisite. If you’d like to use WhatsApp on your PC, you’ll find detailed instruction on Cnet, as well as an instructional video.

Unfortunately with the convenience and accessibility of WhatsApp also comes risk. If you use WhatsApp on a regular basis, look out for the following scams.

A new Wangiri campaign, where users are encouraged to make expensive international calls, is doing the rounds.  Wangiri is a type of cellphone fraud where the perpetrator randomly calls cell numbers and puts down the phone after one ring. A missed call shows on the victim’s phone and he calls back since he believes the call was intended for him. In actual fact he’s calling a very expensive premium number.

In this instance WhatsApp users receive a message with a contact card attached and the message asks the cellphone owner call back. Read more on this scam here.

A second example is an SMS campaign which could cost WhatsApp users R210-00 a month. An SMS with the following wording is received:

“You have not updated to the latest WhatsApp add-ons. Click here now [URL]. (Free MSG) 31655 optout dial 0110621424”.

A link guides users to a screen with the message “Update your wall 4 WhatsApp”. Fine print below indicates that you’re actually subscribing to a social network called Buddiechat, which will cost you R7-00 per day.

WhatsApp users unknowingly click on the link because they believe it’s legitimate  WhatsApp communication or because they’re too preoccupied to read. Read the full article on mybroadband. 

 

Tune in to Bits & Bytes

Friday, November 7th, 2014

radio2This September Bits & Bytes celebrated one year on air. Initially Bits & Bytes started out as a newsletter to staff, but over time we realised we have too many interesting things to share, we just can’t keep it to ourselves anymore. But what more could we do?

The answer was obvious. With an audience of 30 000 listeners between the ages of 14 and 28, we knew MFM would be the perfect match. And so Bits & Bytes, the radio version was born. For the past year and a bit we had a weekly slot during the AM-PM-show at 11:45 on Tuesday mornings.

Initially Tian Petersen was the IT voice, but we decided to add some spice and Marc-Allen Johnson joined later.

Bits & Bytes on air isn’t another institutional mouthpiece to promote IT, but became a platform to discuss all kinds of technological developments, gadgets – some weird and some even handy. With each programme we try to combine news relevant to students and staff, as well as interesting developments on the technological front, in an informal style.

We do realise not everyone will be able to listen to the show due to limited access, therefore we have an alternative so you won’t miss out on anything. You can now also listen to the broadcasts online by browsing to WWW.SUN.AC.ZA/BB.

There you will find all 34 broadcasts Tian and Marc-Allen has done.  Just click on the mp3 link. These clips are hosted within the SU network and won’t rocket your internet costs – so you can listen with ease. You’ll also find all previous versions of the Bits & Bytes newsletter.

If you do want to listen to the direct broadcast, tune in every second Tuesday at 11:45 on the AM to PM Show on MFM with Eduard and our two resident IT gurus, Tian and Marc-Allen.  Click HERE to listen to MFM live.

You’re also welcome to send comments and questions during the show via Twitter and if there’s enough time Tian will address them. Tweet us at @ITStellenUni!

So what do we really do?

servicecatFor the most part IT are considered the people who “fix our computers” or the e-mail or internet. As that may be, that’s not all IT does.

To give everyone a wider understanding of all the services Information Technology’s staff keeps them busy with for most of the 365 days a year, we’ve compiled a user-friendly (we believe!) service catalogue in website format.

The catalogue contains all our services – those you already know about and those you had no idea about. Together with a description of each service, you’ll find instructions on how to apply for it, which times it’s available and who to contact regarding any inquiries about the services.

We also included a handy A-Z index for easy access, a sitemap and relevant links to our other resources. A web part showing all our latest news posts as well as our Twitter feed in real time will keep you up to date on everything you need to know.

We’d love for you to have a look at it at www.sun.ac.za/itservices and let us know what you think – good or bad. Are the services easily accessible and clearly explained for example?

For any suggestions or comments, please contact us by sending an e-mail to helpinfo@sun.ac.za. A feedback and contact button is also available on the bottom bar on the page for fast access.

Would you be able to disconnect?

Whether it’s an increasing phenomenon or we’re just more aware of it, addictive social media and internet behavior is becoming more prevalent. To such an extent that internet addiction treatment camps are commonplace in China. According to psychiatrist and neuroscience researcher Sean Luo of Columbia University “3.7 to 13 percent of U.S. and 10 percent of South Korean Internet users express some symptoms of inappropriate Internet use.”(http://www.cbsnews.com/news/how-real-a-risk-is-social-media-addiction/)

Last week it was reported that doctors in the USA submitted a man into the US Navy’s substance abuse programme, because he was apparently addicted to Google Glass. He wore the headset for up to 18 hours a day and when it was removed, experienced serious withdrawal symptoms. Even when he was not wearing it, he attempted to tap his right temple, which is where the device is activated. He was diagnosed with internet addiction disorder (IAD).

This isn’t a new phenomenon. In 1996, shortly after internet became part of our lives, internet addiction was already recognised as a possible psychiatric disorder. Even though it’s not officially listed in the latest DSM manual (Diagnostic and Statistical Manual of Mental Disorders), used by psychiatrists, it has been argued that it should be. Psychiatrists also prefer the term Problematic Internet Use (PUI), avoiding the use of the word addiction. PUI refers to excessive computer use interfering with daily life.

The diagnosis of internet addiction isn’t an easy one as it’s not the medium someone becomes addicted to, but rather the available online content. The internet is merely the platform. It has also been observed that IAD could be a symptom of another underlying disorder, instead of a disorder on it’s own.  Many other related addictions can fall under the general term IAD, for example a gambling addiction, addiction to cyber relationships, online shopping, etc. (more detail on IAD can be found on www.wikipedia.org)

Would you be able to disconnect, even if only for a day? How about trying survive this weekend without Facebook, Twitter or e-mail to start? Imagine how much more time you might have on your hands …

In 2013 Paul Miller, an American Technology Journalist from Springfield, Missouri and senior editor for The Verge decided to disconnect from the hyper-connected world in an attempt to ‘find himself’ and become more productive. He abandoned the internet and disconnected from all Social Media, returning to a life before the net, apps and smartphones. Watch the video below to see what he learnt from the experience.

Want to read a novel in 90 minutes?

Friday, September 26th, 2014

Too much to do, not enough time! Sounds familiar? No wonder we feel frustrated when we have to read large amounts of material in limited time.

Due to our dwindling attention span caused by technology and the emergence of e-books, rapid serial visual presentation technology, or RSVP is becoming more popular. It’s not new technology, and in fact, has been around for almost a decade now. (*see below for alternative speed readers)

spritzThe latest of these applications is Spritz. The Boston-based company specialises in text streaming technology and how it can be integrated into our daily communication. When Samsung released the Gear S Smartwatch Spritz even came pre-installed with it.

According to Spritz, when we read, we only use 20% of our time to actually process what we’re reading. The other 80% is spent wasted moving your eyes around and scanning for the “Optimal Recognition Point” (ORP)

The ORP is a specific section of a word your brain needs to process to understand the written text. It then assembles each word into an understandable sentence. Spritz does this thinking for you by highlighting the OPR in red and aligning them all at the same place on your screen. Subsequently your eyes focus on only one spot, which in turn causes you to read faster.

Spritz allows you to choose your own reading speed ranging from 250 words per minute to 1000 words per minute. With practice your reading speed will increase and you’ll be able to not only read efficiently, but also comprehend what you’ve read.

We’ve tested Spritz and it does enable you to read much faster than you normally would. If you need to read documentation for work or research, Spritz might well be the answer. But do you really want to read a novel in an hour and a half? (Quite possible according to Spritz)

This way of reading might however be beneficial for people suffering from dyslexia, a short attention span or other reading disabilities.

Spritz is available in both an application format for your phone or e-reader, but also as an add-on called Spritzlet for your web browser. Both can be downloaded for free at www.spritzinc.com.

*Alternatively also try SpreederQuickreaderRead Quick or Firefox’s RSVP reader.
