Mathematica at SU

Thursday, July 16th, 2015

Modern computational tools are important in diverse disciplines, and they are clearly essential in fields requiring sophisticated mathematics, complicated numerics or the processing of large amounts of data.  Over time each field has developed an array of their own specialised solutions or packages.

However, a campus-wide license has recently been obtained for the package Mathematica developed by Wolfram Research Inc. Mathematica is one of a very small group of extremely powerful, high-level software packages specialising in advanced algebraic, numerical and image processing computation.

mathematicaAt Stellenbosch University colleagues have been using it successfully in the biological, mathematical and physical sciences, and also in economic and management sciences for both teaching and research.  It is therefore really worthwhile exploring whether it is suitable for your academic work too.

In addition to its function as a high-performance research tool it is has also developed to be an efficient, user-friendly teaching device.  It is powerful beyond any other general symbolic manipulation package, and easy to use at base level.  Mathematica places the emphasis on computation of mathematical objects and comes with its own formal language.  It also interfaces with an extensive audited database, which might be known to some readers through the Wolfram Alpha website.

For a license to use the Mathematica software, please contact narga@sun.ac.za.

Register for Wi-Fi access

Tuesday, July 14th, 2015

If you are required to work on more than one SU campus and need an internet connection, there’s something you have to keep in mind.

To use Wi-Fi on the Stellenbosch, Tygerberg or USB campuses you will have to register your devices separately on all three campuses. If you’re already using Wi-Fi on your home campus, it doesn’t mean you’re automatically registered for others.

To use the Secure of  MatiesWifi SSIDs elsewhere, register your device by e-mailing the following information to help@sun.ac.za:

  • Building
  • Room number
  • Username
  • Asset tag of the laptop or a description of the device
  • Network card address (also known as the MAC address)

Windows 10 is on its way

Friday, June 12th, 2015

If their direct marketing approach is anything to go by, Microsoft is extremely eager to upgrade clients to their latest operating system. Over the past two weeks, Windows users have been confronted by a pop-up message on their computer screens, marketing Windows 10.

cortana“What happened to Windows 9 you ask?” It would seem as if Microsoft decided to skip the next logical option, Windows 9, and go directly from version 8 to 10.

The company claims that it’s such a huge leap from Windows 8 tot 10, it wouldn’t make sense to stick to the usual numeric naming convention. Given that Windows 8 hasn’t been the most popular, nor the most successful operating system, Microsoft might want to distance them from it as much as possible.

Whatever the reason, Windows 10 was presented to the media in September last year, and will, according to Microsoft, be available to the public at the end of July.

The bigger news however, is that Microsoft will be offering a free upgrade to Windows 10 to all their clients using the Windows 7 Service Pack 1 or Windows 8.1.

Some staff, depending on the versions of Windows you have installed, might have received a notice from Microsoft asking if they’d like to upgrade. If you say “yes”, a copy is reserved for you and when it’s available another notification will be sent. You can then decide if and when you want to install it.

BUT, just because Microsoft sent you the message, it doesn’t mean your computer can necessarily handle the new operating system.

And, as with most new software, the first release tends to have some glitches and the occasional bug.

IT will first conduct a thorough software testing and will then notify users when it’s safe to install and use it. Please hang in there for a bit longer and keep an eye out for news on Twitter and in Bits & Bytes.

If Microsoft’s marketing material is anything to go by, the new version seems promising and possibly an improvement on Windows 8. (more information is available on Microsoft’s website.

Keep in mind that some of the new functionality isn’t available from the start. Windows Media Center and the previously installed software needed to watch DVDs are also some of the functions that ended up on the chopping board.

The biggest visible change will probably be Cortana, a personal assistant –  Microsoft’s answer to Apple’s less successful Siri. Microsoft Edge will also replace Internet Explorer as a web browser.

More answers regarding the upgrade to Windows 10, can also be found on the Guardian‘s website.

Think you’re safe online?

Memeburn, a website specialising in tech news and analysis recently reported on the state of cyber security in South Africa. (Read the article here)

According to the article, it was announced during the 2015 Security Summit in Johannesburg that over the previous six month, South Africa was the most popular target in Africa for criminal cyber attacks. DDOS attacks in Africa also increased 150% over the past 18 months.

Antonio Forzieri, an executive at Symantec, stated that one out of 214 e-mail sent in South Africa last year, was a spear phishing attempt.

South Africans are losing R2.2 billion per year to cybercrime. Statistics like these emphasise the importance of being informed and careful with personal information.

Online sales are on the increase and providesan additional platform for cybercrime.

onedollarKaspersky Lab, a company renowned for their expertise in security, launched a new project which, in a very visual, simple and interactive way, demonstrates the danger of cyber threats.

The one dollar lesson is an animated website which shows what happens to your money when you shop online and your information is intercepted.

One dollar lesson also hosts three training modules – each of which shows one dollar’s virtual trip to the bank and the possible obstacles it can encounter along the way.

Don’t assume you know everything there is to know about cyber safety. Stay up to date on new cyber threats and be careful with your personal information.

New IT building – greenest on campus

Friday, May 15th, 2015

In September the Information Technology (IT) division will enter a new era. Not only will we be moving to a new building, our new home will also be the first truly “green” building on campus.

A wide range of sustainability characteristics have been incorporated in the new building’s design and can be considered according to the Green Building Council of South Africa’s Green Star Office rating tool categories.

Energy efficiency and renewable energy: Solar photovoltaic energy generation on the roof; optimal northern orientation and window sizing; shading elements; vertical garden on the northern aspect to minimise heating and cooling; usage of river water for cooling; low energy lighting and smart lighting.

Indoor environment quality (IEQ): Natural lighting; ventilation; minimisation of noise.

Transport: Bicycle store and facilities for cyclists; optimal parking spaces.

Innovation: The vertical garden; the use of river and rainwater for air-conditioning plant cooling.

The building should not be seen as merely a space hosting a department, but also an integral part of the IT Division’s work system – the people, processes they execute and the spaces and facilities of the building all form an integrated whole.

The building can contribute to the goal of creating a new working culture, establishing new work methods and, above all, encouraging collaboration and communication.

Developing new ways of working and a different work culture is now more important than ever as we find ourselves in the Information Age. As the focus shifts to the application of information and communication technologies (ICT) within Stellenbosch University’s strategy, the IT Division has to be able to meet higher expectations. The new building can be viewed as a tool, amongst others, to help meet these expectations.

The nature of knowledge work in the Information Age, in which the IT Division engages, is increasingly team-oriented, social, requiring intensive communication, interactions, knowledge sharing, continuous learning and consultation. The ability to collaborate, breaking out of siloed thinking, effective networking and flexibility become valued capabilities.

The new building features large “open plan” working areas with abundant natural lighting and tracts of glass – much like the campus facilities of admired technology companies such as Google and Apple. Quality, utility and flexibility of furnishings and fittings are also vital as teamwork requires flexible furnishings that can be altered easily and quickly to accommodate new work areas.

Adequate, well-resourced meeting spaces and breakaway areas are required in order to achieve a balance between shared and private workspace in innovative ways. Digital communications facilities in these spaces must make remote working and virtual meetings easy and effective.

Finally, the work environment must be healthy, encourage creativity and collaboration and must be a place where people want to work and spend time.  A working environment that is welcoming, open and does not reinforce hierarchies and promotes flexibility and communication will contribute to the transition to a next-generation IT Division.
