Confused about visitors’ activation?Verward oor besoekersaktivering?

Friday, October 4th, 2013

Two weeks ago we introduced a new decentralised process for activating access for vistors to the SU campus (read the article here) However, it seems that some confusion remains regarding the steps to follow and how the new process works. 

To explain this in a very simple way, we created a diagram explaining  the basics. All this information, as well as FAQs, is also available on our wiki.

Twee weke gelede het ons `n nuwe gedesentraliseerde proses vir die aktivering van toegang van besoekers aan die US-kampus aangekondig. (lees die artikel hier) Daar bestaan egter nog `n mate van verwarring oor die prosedures en hoe dit werk.

Om die proses eenvoudiger uit een te sit, het ons `n diagram saamgestel wat presies verduidelik hoe die stappe werk. Al dié inligting is ook in teks formaat op ons wiki beskikbaar.

Geared for the futureGerat vir die toekoms

Friday, October 4th, 2013

Do you still remember those enormous Casio watches with the built in calculators? Well, don’t start sniggering just yet (besides, we know you also had one). Because soon you’ll want a large watch again and this time around it will be able to do more than just adding and subtracting.

The Samsung Galaxy Gear smart watch was recently launched in Berlin by Lee Young-hee, Samsung‘s vice president of mobile technology, two weeks before the Berlin IFA electronic consumer show.

With Samsung’s new smart watch you’ll be able to make calls, browse the internet and manage your e-mails. All this while you’re looking the part  – bodyguard meets FBI agent.

Other useful extras include a camera, various applications such as Evernote and Pocket, as well as MyFitnessPal and RunKeeper for the fitness fanatics among us. For those who prefer wine above exercise, the Gear comes with Vivino Wine Scanner – an app which allows you to take a photo of  a wine label and immediately have access to the wine’s information.

But BEFORE you get too excited, I have to warn you that, to use a Galaxy Gear, you also need a Galaxy Note. It is estimated that the Gear will be available during October for the recommended price of  R4 599. The latest Galaxy Note model, with which the Gear is compatible, has been available since 27 September at R8 999.

In total this comes to the considerable amount of approximately R14 000. Not necessarily an option for someone earning an average salary, but at least the technology is now available and with a little bit of patience, we all will be able to afford one one day.

More information on the Samsung Galaxy Gear can be found on Samsung’s website

Onthou jy nog daai ou, groot Casio horlosies met die ingeboude sakrekenaars? Wel, moenie te hard lag nie (buitendien, ons weet jy het ook een gehad). Een van die dae gaan jy weer ‘n groot horlosie wil hê en dié keer kan dit meer doen as net optelsomme.

Die Samsung Galaxy Gear slimhorlosie is onlangs in Berlyn, twee weke voor die  Berlyn IFA elektronika verbruikerstentoonstelling, deur Lee Young-hee, Samsung se vise-president van mobiele tegnologie, bekendgestel. 

Met Samsung se nuwe slimhorlosie kan jy telefoonoproepe maak, die internet gebruik en e-posse bestuur. Dit alles terwyl jy soos ‘n wafferse lyfwag of FBI-agent lyk.

Ander handige ekstras sluit `n kamera,  toepassings soos Evernote en Pocket, sowel as MyFitnessPal en RunKeeper vir die meer sportiewes onder ons, in. Vir diegene wat wyn bo  sport verkies, is daar Vivino Wine Scanner, waarmee jy `n wynetiket kan afneem en dadelik die inligting oor die betrokke wyn tot jou beskikking het.

Maar voordat jy TE opgewonde raak – om die Galaxy Gear te gebruik, moet jy ook `n Galaxy Note besit. Dit word beraam dat die Gear reeds dié maand beskikbaar sal wees teen die aanbevole bedrag van R4 599. Die nuutste Galaxy Note model, waarmee die slimfoon versoenbaar is, is reeds vanaf 27 September beskikbaar teen R8 999. 

Die totaal van die twee toestelle kom dus tot die aardige bedraggie van ongeveer R14 000. Nie noodwendig `n opsie vir die diegene wat `n gemiddelde salaris verdien nie, maar ons kan met sekerheid sê dat die tegnologie nou beskikbaar is en ook eendag meer bekostigbaar sal wees vir die res van ons. 

Meer inligting oor die Samsung Galaxy Gear kan gevind word op Samsung se webwerf.

WiGig – new generation WiFi?WiGig – nuwe generasie WiFi?

Friday, September 20th, 2013

Just when we got used to all the pros and cons of WiFi, a new contender we don’t know much about yet, appears on the horizon. Let’s look at the strengths and weaknesses of  WiGig.

WiGig is another wireless standard just like WiFi, but in spite of this there are some significant differences.

WiGig’s  range is considerably closer than WiFi, won’t easily reach past 10 metres and doesn’t particularly like to go through walls. So why would you want to use it?

WiGig is fast, faster than the Wifi we’re used to. It operates on a much higher frequency (60GHz ) than traditional bandwidths and mobile signals and can deliver speeds of up to 7Gbps. lewer. However, as soon as your devices are further away, speed performance decreases rapidly.

Experts therefore recommend that WiGig be used for home entertainment systems, tablets and home pcs and in addition to your existing WiFi connection.  

If energy saving is important to you, you can consider WiGig with a clear conscience as it’s been designed as a low energy alternative. It also claims to use five times less energy than WiFi and radio signals are set up to avoid congestion and send signals directly to it’s goal. 

WiGig was established by the Wireless Gigabit Alliance, which included members like Broadcom, Cisco, Intel, Microsoft, Dell, Nokia, Toshiba, Qualcomm, NEC, Panasonic and other large corporations. At the moment the WiGig standard is currently going through various certification programmes, but according to estimations these will be completed by the end of 2013.

Net toe ons gewoond geraak het aan WiFi en vrede gemaak het met sy nukke en grille, verskyn daar `n nuwe speler op die veld. Een waarvan ons tot nou toe nie veel van geweet het nie. Kom ons kyk wat is WiGig en vergelyk sy sterk- en swakpunte. 

WiGig is bloot nog `n draadlose (wireless) standaard soos WiFi, daar is tog `n paar duidelike verskille. 

WiGig se reikwydte is aansienlik korter as WiFi, strek nie maklik verder as 10 meter nie en sukkel om deur mure `n sein te stuur. So, hoekom sal `n mens dit wil gebruik?

WiGig is vinnig, vinniger as die Wifi waaraan ons gewoond is. Dit werk op ‘n veel hoër frekwensie (60GHz ) as die tradisionele bandwydtes en mobiele seine soos 3G kan blykbaar tot 7 Gbps lewer. Sodra jou toestelle egter verder weg is, verminder die spoed bitter vining.

Kenners beveel dus aan dat WiGig gebruik moet word vir tuisvermaak-toestelle, tablette en tuisrekenaars en dat jy dit gebruik as aanvulling tot jou reeds bestaande WiFi-konneksie. 

As die besparing van energie vir jou belangrik is, kan jy WiGig met `n skoon gewete oorweeg aangesien dit ontwerp is as `n lae energie alternatief en aanspraak daarop maak dat dit vyf keer minder energie verbruik as WiFi. Radioseine word geoptimiseer om die beste resultate te gee, oorlading te verminder en die sein direk te stuur waarheen dit moet gaan.

WiGig het ontstaan by die Wireless Gigabit Alliance wat lede soos Broadcom, Cisco, Intel, Microsoft, Dell, Nokia, Toshiba, Qualcomm, NEC, Panasonic en ander groot maatskappye insluit. Op die oomblik gaan dié standaard eers deur verskeie sertifiseringsprogramme, maar volgens beraming sal dit teen einde 2013 afgehandel wees.

Meet TEDOntmoet vir TED

Friday, September 20th, 2013

TED has been inspiring millions around the world and most of the time he only has 18 minutes to do it! Quite the motivational speaker, isn’t he?

Good thing TED isn’t just one person otherwise he would’ve been exhausted after almost 30 years of talking.

TED talks began as a simple attempt to share what happens at various TED conferences around the world. It started off way back in 1984 when people from three different worlds – Technology, Entertainment and Design – came together at a conference to share ideas. They realized that some of these ideas might actually be cool and worth sharing with other people. And so TED talks was born.

In spite of it’s popularity TED remains a nonprofit organization and has grown exponentially over the years.  Along with two annual conferences, the TED Conference and TEDGlobal, TED includes the award-winning TED Talks video site, the Open Translation Project and TED Conversations, the inspiring TED Fellows and TEDx programs, and the annual TED Prize.

But the most popular of all these seem to be TED talks. As talks were given at conferences around the world, they were released online and quickly attracted a global audience who liked what they heard. Since June 2006, they have been offered for free viewing online, under Attribution-NonCommercial-NoDerivs Creative Commons license, through TED.com.

In January 2009 the then amount of videos had been viewed 50 million times. In June 2011 the amount of views totaled 500 million, and on 13 November 2012, TED reached its billionth video view.

Initially speakers came from the three fields of Technology, Entertainment and Design, but over the years they have included scientists, philosophers, musicians, religious leaders, philanthropists and many others. Previous presenters include Bill Clinton, Jane Goodall, Malcolm Gladwell, Al Gore, Gordon Brown, Richard Dawkins, Bill Gates, Google founders Larry Page and Sergey Brin, and many Nobel Prize winners. Since speakers are given only 18 minutes, their ideas have to be conveyed in the most innovative and interesting way to capture their audience and often also though storytelling.

As of May 2013, over 1,500 talks are available free online. Every week 5-7 new talks are being published. Topics range from a talk on why bees are disappearing to how to make stress your friend and everything in between. Whether you’re looking for something informative, inspiring, ingenious or just plain jaw-dropping, you’ll find it here.

TED inspireer al vir jare lank miljoene mense regoor die wêreld en hy het elke keer net 18 minute om dit te kan doen! `n Indrukwekkende motiveringspreker, dink jy nie so nie? 

Die ook maar goed TED is nie net een mens nie, anders sou hy al doodmoeg gewees het na 30 jaar se gepraat.

TED talks het begin as `n eenvoudige poging om dit wat gebeur by die verskeie TED-konferensies reg oor die wêreld, te deel met ander. In 1984 het `n groep mense uit drie verskillende wêrelde – Tegnologie, Vermaak en Ontwerp – bymekaargekom by `n konferensie om idees uit te ruil. Terselfdertyd het hulle tot die ontdekking gekom dat van hierdie idees eintlik nogal innoverend is en met ander mense gedeel moet word. En so het TED talks ‘n lewe van sy eie gekry.

Ten spyte van TED se wêreldwye gewildheid, bly dit steeds `n nie-winsgewende organisasie wat oor die jare geleidelik gegroei het. Buite twee jaarlikse konferensies – die TED Konferensie en TEDGloba, sluit die TED-handelsmerk ook die bekroonde TED Talks video webwerf, die Open Translation Project en TED Conversations, die inspirerende TED Fellows, die TEDx-programme en die jaarlikse TED-prys.

Maar die mees populêre van al hierdie blyk die TED talks te wees. Omdat die praatjies by konferensies regoor die wêreld gelewer word, is dit aanlyn vrygestel en het dit kort voor lank `n globale gehoor gelok. Sedert Junie 2006 kan die praatjies gratis aanlyn gekyk en afgelaai word op TED.com onder die vaandel van die  Attribution-NonCommercial-NoDerivs Creative Commons license. 

In Januarie 2009 is die toe-beskikbare videos 50 miljoen keer gekyk. In Junie 2011 het dit gestyg na 500 miljoen en op 13 November 2012, het TED sy biljoen perk bereik.

Aanvanklik het sprekers vanuit slegs drie velde – Tegnologie, Vermaak en Ontwerp – deelgeneem, maar oor die jare het dit uitgebrei na wetenskaplikes, filosowe, musikante, geestelike leiers, filantrope en vele meer. Vorige aanbieders sluit Bill Clinton, Jane Goodall, Malcolm Gladwell, Al Gore, Gordon Brown, Richard Dawkins, Bill Gates, Google-stigters Larry Page en Sergey Brin, en ander Nobelpryswenners, in.

Aangesien sprekers normaalweg net 18 minute toegeken word, moet dit wat hulle oordra, op die mees innoverende en interessante maniere vertel word om die gehoor se aandag te hou en dikwels word dit ook dan deur middel van storievertelling gedoen.  

Vanaf Mei 2013 is meer as 1500 praatjies gratis aanlyn beskikbaar. Elke week word 5-7 nuwe praatjies gelaai. Onderwerpe strek van die verdwyning van bye tot hoe om stres te hanteer en alles tussen-in. Of jy iets informatief, inspirerend, geniaal of net eenvoudig verstommend soek, jy sal dit daar kry.
