Stellenbosch IT staff actively involved with ASAUDIT management

Wednesday, August 1st, 2012

The purpose of ASAUDIT is to promote and advance the use and support of computing and information technology at South African universities, and to further develop relationships with key members in the Higher Education sector both locally and internationally.

The association strives to promote professional skills and conduct in university ICT management and to serve as unitary voice for the South African Higher Education IT profession and to provide mutual support mechanisms to its members by encouraging development and application of standards and best practices through the sharing of expertise among members and colleagues in organising informative events.

ASAUDIT focuses on the sharing of knowledge and collaboration between University IT divisions. To ensure that this is facilitated properly special interest groups (SIGs) see to the needs of universities. No less than six Stellenbosch University IT staff are involved in these groups.

Ralph Pina heads the Green IT SIG group. This group ensures that  IT operations are ecologically sustainable (i.e. that energy and material throughputs are minimised) and on ICT’s role in enabling sustainability elsewhere in the university. The SIG share information about Green IT and will be emphasising cross-institutional benchmarking using Green IT indicators.

Johan Kistner is responsible for the ECM SIG group, aiming to provide a forum to share experiences in electronic content management, as well as to collect a library of best practices. The SIG is not limited to any particular brand or solution; it rather strives to serve the interest of all member institutions. Institutions share their knowledge and assist each other with advice. In addition, speakers from the industry are invited with restraint on the commercial tone.

Mark-Allen Johnson was recently chosen as co-chairman for the Mobile Special Interest Group. They offer the opportunity for technologists, teaching and learning specialists as well as other stakeholder groupings within the South African Higher Education sector to collaborate on leveraging the potential of mobile devices. The SIG endeavours to facilitate conversations locally and through international engagement on the theory as well as practice of all areas related to mobility as it applies to higher education.

Petro Uys and Marinka Naude are both members of the Skills Development SIG, whilst IT’s Managing Director, Helmi Dreijer leads the Procurement Committee.

New method for access to free Library e-resourcesNuwe metode vir toegang tot gratis Biblioteek e-bronne

Friday, July 27th, 2012

As of 1 July 2012 free Internet access to the electronic subscription resources of the SU Library Service is only available from the Library’s website.

As announced in a previous Bits-‘n-Bytes article, the former method used to provide free access – namely a configuration setting in the end-user’s browser called the PAC file – is for a number of reasons no longer a technically feasible method to employ.  Free Internet access to electronic subscription resources is therefore now only available by following the applicable links on the Library website.  In such a way the cost for accessing the resources is automatically discounted from the end-user’s monthly Internet bill.  These links can also be bookmarked in web browsers to serve as shortcut links to electronic resources.

Users are still encouraged to use Inetkey whilst accessing subscription electronic resources, because it will speed-up the download of non-academic content from these e-resources sites.

For enquiries contact Wouter Klapwijk.Vanaf ingang 1 Julie 2012 is gratis Internet toegang tot die US Biblioteekdiens se subskripsie elektroniese bronne slegs beskikbaar vanaf die Biblioteekdiens se webwerf.

Soos met ‘n vorige uitgawe van Bits-and-Bytes berig is die metode waarmee voorheen gratis toegang bewerkstellig was – naamlik ‘n verstelling in die gebruiker se webleser bekend as die PAC lêer – weens ‘n verskeidenheid van redes nie meer langer ‘n tegniese haalbare opsie om gratis toegang te bewerkstellig nie. Gratis toegang is dus voortaan slegs beskikbaar deur enige van die elektroniese bronne skakels op die Biblioteek se webwerf te gebruik. Sodoende word die gebruiker outomaties onthef van die Internet koste vir toegang tot subskripsie elektroniese bronne. Hierdie skakels kan ook deur middel van die gebruiker se webleser geboekmerk word om as snelskakels tot die elektroniese bronne aangewend te word.

Gebruikers word nogtans aangeraai om deurgaans Inetkey te gebruik, want dit sal die aflaai van die nie-akademiese inhoud met die gebruik van elektroniese bronne versnel.

Navrae kan gerig word aan Wouter Klapwijk.

All IT news now also available on TwitterAlle nuutste IT-nuus nou ook beskikbaar op Twitter

Thursday, July 19th, 2012

Information Technology has always been a fast paced, ever developing environment and the same goes for Stellenbosch University’s IT department. The past few months we’ve been trying to improve communication with you, our clients to keep you updated with IT developments on campus. We’ve started a fortnightly newsletter, started to utilise our blog more effectively and at the moment we’re streamlining our self help wiki page to make your life  easier. However to keep up with our fast paced environment, we needed something more interactive to give instantaneous updates to users. So at last, we’re happy to announce that IT can now also be found on Twitter. Follow us at @ITStellenUni, retweet and let us know what you think.

Informasie Tegnologie was nog altyd `n vinnige, dinamiese omgewing en Stellenbosch Universiteit se IT-afdeling is geensins anders nie.

Die afgelope paar maande het ons probeer om kommunikasie met jou, die gebruiker, te verbeter en jou op hoogte te hou van alles wat ons doen en die nuutste IT-verwikkelinge op kampus. Ons het `n tweeweeklikse nuusbrief, Bits & Bytes, begin, ons blog aktief begin gebruik en ons is ook besig om te werk aan `n selfhelp wiki om die lewe vir jou makliker te probeer maak.

Om egter by te hou by ons vinnige omgewing was dit nodig om `n meer interaktiewe kanaal te gebruik om gebruikers onmiddellik in te lig. Ons is dus bly om te kan sê dat IT ook nou op Twitter is. Volg ons by @ITStellenUni, lewer kommentaar en retwiet – ons wil graag hoor wat julle dink.


Galaxy S3 launched in SAGalaxy S3 is hier

Friday, June 8th, 2012

Samsung Electronics’ highly anticipated flagship smartphone, the Galaxy S3, was launched in SA last night.  The phone has been available from mobile operator Vodacom since the end of last month, but MTN and CellC will now be adding the phone to their contract options after last night’s launch. In South Africa alone 50 000 orders were received before it’s release.

The Samsung Galaxy S III is an Android smartphone that was announced by Samsung on 3 May 2012 and the successor to the Samsung Galaxy S II. The device was released in 28 countries, including in Europe, on 29 May 2012, and in India and Malaysia on 31 May 2012.

If you’re interested in the technical stuff, you’ll find all the technical specs on Wikipedia or Samsung’s website. For objective reviews on the Galaxy SIII, read more on CNET.

Samsung Electronics se nuutste vlagskip intelligente foon, die Galaxy S3, is gisteraand na groot afwagting in Suid-Afrika bekendgestel. Die foon is sedert die einde van verlede maand slegs beskikbaar by Vodacom, maar MTN & Cell C sal dit ook na gisteraand se bekendstelling as deel van hulle kontrakportfolio aanbied. In Suid-Afrika is 50 000 bestellings ontvang voordat die foon bekendgestel is.

Die Samsung Galaxy S III is ‘n intelligente Android-foon aangekondig deur Samsung op 3 Mei 2012 en die opvolger van die Samsung Galaxy S II. Die toestel is op 29 Mei 2012 in 28 lande bekendgestel, onder andere in Europa, Indië en Maleisië.

As jy geinteresseerd is in die tegniese detail, sal jy die gedetaileerde spesifikasies vind op Wikipedia of Samsung se webwerf. Vir objektiewe opinies en resensies, lees meer op CNET.

Mirror sites at your disposalSpieëlwebwerwe tot jou beskikking

Friday, June 8th, 2012

Did you know there are selected websites you have free access to? These websites are known as mirror sites.

In computing, a mirror is an exact copy of a data set. On the Internet, a mirror site is an exact copy of another Internet site. Mirror sites are most commonly used to provide multiple sources of the same information, and are of particular value as a way of providing reliable access to large downloads. Mirroring is a type of file synchronization and a  live mirror is automatically updated as soon as the original is changed.

But why the need for more than one version of the same website. A few reasons are:

  1. To preserve a website or page, especially when it is closed or is about to be closed.
  2. To allow faster downloads for users at a specific geographical location. For example, a U.S. server could be mirrored in Japan, allowing Japanese Internet users to download content faster from the local Japanese server than from the original American one.
  3. To provide access to otherwise unavailable information. For example, when the popular Google search engine was banned in 2002 by the People’s Republic of China, the mirror elgooG was used as a way of effectively circumventing the ban.
  4. To preserve historic content. Financial constraints and/or bandwidth prevent the maintainers of a server from keeping older and unsupported content available to users who still may desire them; a mirror may be made to prevent this content from disappearing.
  5. To balance load. If one server is extremely popular a mirror may help relieve this load this server may become overloaded with demand. Alternative download points allow the total number of download requests to be spread among several servers, maintaining the availability of the distribution.
  6. As a temporary measure to counterbalance a sudden, temporary increase in traffic.

Het jy geweet daar is sekere webwerwe waartoe jy plaaslik toegang na kan kry sonder dat jy nodig het om Inetkey te gebruik? Hierdie webwerwe staan bekend as spieëlwebwerf, of te wel `n “mirror site”.

In die rekenaaromgewing is `n “mirror” `n presiese kopie van `n datastel en op die internet is `n “mirror site” die presiese kopie van `n ander internetwebwerf. Spieëlwebwerwe word gereeld gebruik om veelvuldige bronne van dieselfde inligting te verskaf en is veral voordelig as betroubare toegang tot groot aflaaibare leêrs. “Mirroring”  is in kort dus `n tipe leêr sinkroniseringsproses waar die aktiewe spieëlwebwerf opdateer word sodra die oorspronklike webwerf verander.

Maar hoekom is dit nodig dat daar meer as een weergawes van dieselfde webwerf is? Enkele redes hiervoor is:

  1. Om die bestaande weergawe te bewaar, veral as dit gesluit is of gesluit gaan word.
  2. Sodat gebruikers vinniger inligting kan aflaai as dit plaaslik is. (`n Amerikaanse bediener kan byvoorbeeld `n spieëlbeeld hê in Japan sodat Japanese internetgebruikers vinniger data kan aflaai.)
  3. Toegang tot andersins onbereikbare inligting. (Google is byvoorbeeld verban in China in 2002 en `n spieëlwebwerf elgooG is daargestel om steeds toegang te gee.)
  4. Om ouer inligting te argiveer wat te duur word om te huisves op die hoofwebwerf.
  5. Om die lading in internetverkeer te verlig.

Voordat jy dus groot leêrs en sagteware aflaai vanaf `n internasionale webwerf en jou internetrekening opjaag, maak eers seker dat daar nie `n plaaslike weergawe is nie. Die volgende klompie webwerwe is teen geen onkoste beskikbaar vir jou:
