Connectivity

Travelling without unnecessary costs

Friday, November 15th, 2013

IF you travel abroad on a regular basis, you’ve probably learnt the hard way how expensive cell phone expenses can become once crossing South African borders.

Still, there are ways to save yourself a staggering phone bill if you really need to stay connected when travelling.

Buy a local SIM card

Most travelers don’t realise how easy it is to replace a phone’s SIM card with a local one. Prepaid SIM cards are cheap and it’s easy to load data. Incoming calls are generally free and outgoing calls (local and international) are substantially cheaper as well.

Keep in mind a new SIM card also means a new phone number. If friends and family need to get hold of you, let them know what your new, temporary number while travelling is.

Unfortunately, just like in South Africa, you need to go through the tedious RICA process. To save yourself time and effort, make sure you have the necessary documentation at hand for a painless registration.

Buy a SIM card before leaving

Execmobile or Flyconnected allows you to buy a SIM card before you even board the plane – less hassles when you’re in a foreign land.

Maxroam also provides a prepaid SIM service which can be used in more than 200 countries.

 Skype or TruPhone

Register as a Skype user before leaving and buy call credits. Because it’s a data call and not a traditional phone call, calls can cost as little as 2 cent per minute.

Skype is dependent on your internet connection and unfortunately this influences the quality and stability of your calls.

International call cards

Call cards give travelers the opportunity to use land lines, phone booths and in some cases, even cell phones.

Most airports and convenience stores sell these cards which provide relatively cheap international tariffs. You can also purchase an international call card in South Africa.

Switch off your data services!

The easiest, cheapest and simplest solution still remains switching off your data services before you travel overseas.

Even though you’re not intentionally using data, applications could still be downloading updates in the background or try to establish a connection.

Would you like lessons from Google?

Friday, November 15th, 2013

Given the fast growing MOOC phenomenon (read our article on MOOCs), Google launched an online video university recently.

Google Helpouts is an online service providing a platform for users to collaborate, share expertise and assist other users by means of live, real-time video streaming.

To use this service, you have to be a member of Google+. You will be able to access Helpouts either through your computer or tablet or by downloading the Android app for your cellphone.

Within seconds you can have a personal instructor at your disposal or when it suits you. No limits on time or location exist – you can have access to expert advice any time of day or night.

Helpout schedules a session when it suits you best and outomatically adds it to your Google calendar. An option to be reminded via sms or e-mail also exists to ensure you don’t forget your session.

Thousands of providers have already joined Helpouts and teach in a wide range of specialist fields. Experts or, as Google refers to them, “providers” can be small, medium or large companies, but also individuals.

Even you can host your popular origami class on Helpouts. Just remember, experts have to be approved by Google and need to list their qualifications, prices and schedules.

Unlike MOOCs, Google’s new service comes at a cost.

Clients pay per minute or session for a live video conversation with an expert who gives Google 20% of his fee as payment. Free sessions are also available for some companies as part of their marketing strategy

Payment is made via Google Wallet, which holds your credit card details, and you can pay per session or per minute. If you’re not satisfied with the service, Helpout  will provide you with a full refund – if you request one within 72 hours.

Do you suddenly feel the urge to learn to play guitar? Matt Gibson is waiting for you at Google Helpouts

Mobile technology survey reveals new trends

Friday, November 1st, 2013

Android and Apple mobile phones look likely to dominate share amongst students within a year while Blackberry’s share is dwindling rapidly. The picture has changed significantly since 2012:

mobile-phones

This is just one example of the results of a recent mobile technology survey conducted by the Information Technology division to track trends in students’ mobile devices. The purpose of these surveys (the first was conducted in September 2012) are to identify trends so that relevant university mobile services and strategies can be implemented in future. Understanding the mix of devices that students possess and how rapidly the picture is changing, is crucial for informed planning and decision-making.

Another unexpected trend is the slow penetration of tablets on campus. Since the vast majority of students have daily access to a laptop, ultrabook or notebook, the tablet seems to be an optional “third” device, which 47% of students can’t afford and 25% prefer not to use. Only 28% of respondents have a tablet, almost half of which are Apple iPads, closely followed by Android tablets. Students indicate that the take-up is likely to increase but accelerate slowly.

Unfortunately awareness of the national Student Technology Programme, which provides students with the opportunity to purchase heavily discounted tablets, laptops and notebooks, is also still lacking.

On the positive side students consistently rate mobile services and content related to learning and academic events and schedules as the most important. It is possible that as more learning content, including e-textbooks, becomes available via mobile devices, for offline consumption as well, that the penetration of tablets may accelerate.

More surveys will be conducted in the foreseeable future to discern trends and changes over time and students are encouraged to participate.

2832 students out of 32266 invitees responded.

Free YouTube?

Friday, November 1st, 2013

If you’ve been surfing YouTube the past week, whether for academic purposes or for your video fix, you might have noticed something interesting – Inetkey wasn’t always necesary to access videos. And you observation would be correct.

Good news for us, but we first we need to explain how it works so you won’t be caught off guard.

Stellenbosch University’s internet is routed through Tenet (The Tertiary Education and Research network), a network infrastructure aiming to provide the best possible internet infrastructure to academic institutions. For this reason Tenet’s server is open and accessible to SU staff at no cost and without Inetkey.

But how is this relevant to YouTube? Tenet is hosting a version of YouTube on it’s server cache to enable easier and faster access for their users.

To establish which network should be used for a request and to select the shortest route  for traffic to travel to follow, Google uses algorithms, also known as geo-tagging. In our case Google decides to direct your YouTube request to Tenet instead of one of their servers located overseas.

The risk in the current situation is that Google might decide to use another cache for optimal network capacity and free content will change to paid content once again.

All YouTube content isn’t necessarily part of the cache. Tenet caches the data according to demand. To ensure you don’t pay, keep’Inetkey closed when browsing YouTube.

However, until Google changes it’s route, you can play around on YouTube to your heart’s content. Just remember to keep your Inetkey closed, otherwise you’re in for a big surprise at the end of the month.

How to safely remove media

Friday, October 18th, 2013

It’s 4:32 on a Friday afternoon. You’re exhausted after a week of non-stop dramas and just want to switch off you computer, go home and enjoy the weekend. Downstairs your lift club is anxiously waiting for you to join them. You’ve been reminded of this by their persistently timed missed calls every minute.

Unfortunately at 4:31 you remembered you need to copy a specific document and it’s writing to your flash disk at the pace of a snail wading through quicksand.

Now the question is – do you just rip it out of your laptop and rush downstairs before you have to hike home? Do you wait patiently for it to finish copying? Or do you follow the prescribed, correct steps to eject a USB device? After all how dangerous can it be to remove the flash drive or external hard drive without ejecting it?

When you plug a USB device into your PC, whether it’s your camera, flash drive or external hard drive, you allow it to write and read data to the device. Some data will be cached during this process. 

When data is cached, it’s not immediately written to the USB device, but kept in the PC’s memory. If you remove the device before information is written or while it’s being written, your data will become corrupt. 

However, Windows automatically disables caching on USB devices, unless you enable the function yourself. Therefore, in most cases, you can remove a device without clicking on ‘Safely Remove Hardware’, but only when no data is being written or read by the device. If the device is flashing and data is being copied or read, you run the risk of ending up with corrupt, unusable data.

See the Safely Remove Hardware’ option as your safety net – it’s just an extra precaution to ensure you don’t damage your data. When using it, your files will close properly and all the metadata will be preserved with the file. 

For more information about safe media ejection read this thorough explanation on the How to Geek website.
