Communication

A little bird told meEk het `n voëltjie hoor fluit

Friday, July 24th, 2015

twitter-bird-blue-on-whiteHave you ever heard of Larry the bird?  Yes, the Twitter bird has a name.

We’re all familiar with the online social networking service called Twitter, but do we know more than the fact that it consists of 40 character “tweets”?

Twitter, or twttr as it was known initially was created in March 2006 by Jack Dorsey, Evan Williams, Biz Stone and Noah Glass during a daylong brainstorming session. Dorsey explained the origin of the “Twitter” title as follows:

“…we came across the word ‘twitter’, and it was just perfect. The definition was ‘a short burst of inconsequential information,’ and ‘chirps from birds’. And that’s exactly what the product was.”

“twttr” was used in the beginning since the domain twitter.com wasn’t available immediately. Six months later at Twitters launch, the domain was purchased and the name changed to the one we now use.

Almost ten years later Twitter Inc. is still based in San Francisco and has more than 25 offices around the world with more than 500 million users.

Through the years Twitter developed from being a social tool people use to tweet their experiences and opinions to a useful tool for marketing, education, news, as well as for emergency communication. Twitter fulfilled an important function during the San Francisco earthquakes and Boston marathon bombings. In South Africa Twitter proved useful in updating us on the Cape Town fires and subsequently also assisted with fundraising.

In events such as these Twitter users use a # to group information and make it searchable, for example #capetownfires. As soon as a hashtag’s usage increases and is mentioned at a greater rate, it becomes a “trending topic” and will be visible on the sidebar to all users. These topics show Twitter users the most talked about subjects, whether they are news events or people’s opinions on current topics. (More on the # here)

Colleges and universities also started using Twitter as a communication and learning tool for students. When courses consist of large groups of students, Twitter can be used to facilitate communication between class members.

HOW DOES IT WORK?

Tweets are publicly visible by default, but senders can restrict messages to just their followers. Users can tweet via the Twitter website, compatible external applications (such as for smartphones), or by Short Message Service (SMS) available in certain countries. Retweeting is when a tweet is forwarded via Twitter by users. Both tweets and retweets can be tracked to see which ones are most popular.

Users may subscribe to other users’ tweets – this is known as “following” and subscribers are known as “followers” or “tweeps”. In addition, users can block those who have followed them.

The "@" sign followed by a username is used for mentioning or replying to other users. To repost a message from another Twitter user and share it with one’s own followers, a user can click the retweet button within the Tweet.

Het jy al ooit gehoor van “Larry, the bird?”.  Ja, dis reg, selfs die Twitter-voëltjie het `n naam.

twitter-bird-blue-on-white

Ons is waarskynlik bekend met die  aanlyn sosiale netwerk Twitter, maar weet ons meer as dat dit bestaan uit 40-karakter “twiets”?

Twitter, of twttr soos dit aanvanklik bekendgestaan het, is in Maart 2006 geskep deur Jack Dorsey, Evan Williams, Biz Stone en Noah Glass gedurende `n voldag breinstormsessie. Dorsey het die keuse van die naam Twitter as volg beskryf:

“…we came across the word ‘twitter’, and it was just perfect. The definition was ‘a short burst of inconsequential information,’ and ‘chirps from birds’. And that’s exactly what the product was.”

twttr is aanvanklik gebruik aangesien die domein-naam twitter.com nie op daardie stadium beskikbaar was nie. Ses maande later, met Twitter se amptelike bekendstelling, is die naam verander na die een wat ons vandag gebruik.

Amper tien jaar later is Twitter Inc. steeds gebaseer in San Francisco, met meer as 25 kantore regoor die wêreld en 500 miljoen gebruikers. 

Deur die jare het Twitter ontwikkel van `n sosiale hulpmiddel waarmee mense kommentaar lewer oor hul daaglikse doen en late en lug van opinies tot iets wat gebruik word vir bemarking, onderrig en nuus en veral handig is vir noodkommunikasie. Gedurende die San Francisco aardbewings en Boston-marathon bomaanvalle was Twitter die hoof-kommunikasiekanaal vir die vespreiding van inligting. In Suid-Afrika het Twitter sy nut bewys gedurende die brande in Kaapstad en daarna met die insameling van fondse. 

In gevalle soos hierdie gebruik Twitter-gebruikers `n # om inligting oor `n spesifieke onderwerp te groepeer en soekbaar te maak, byvoorbeeld #capetownfires.  Sodra `n spesifieke hutsteken se gebruik toeneem en dit `n tendens word, word dit `n trending topic en word dit vertoon op die sypaneel vir alle gebruikers. Hierdie onderwerpe wys die onderwerpe waaroor daar die meeste gepraat word, hetsy dit nuusgebeure is of persone se opinies oor aktuele gebeure. (Meer oor # hier)

Kolleges en universiteite maak deesdae ook gebruik van Twitter as `n kommunikasie- en leerhulpmiddel vir studente. Wanneer `n kursus bestaan uit `n groot groep studente, kan Twitter ingespan word om gesprekke tussen klaslede te fasiliteer.

HOE WERK DIT?

Twiets is by verstek sigbaar vir almal, maar versenders kan hul boodskappe beperk tot hul ondersteuners. Gebruikers kan twiet op die Twitter webwerf, deur middel van versoenbare eksterne toepassings (byvoorbeeld toepassings vir selfone) of selfs met SMSe in sommige lande. Hertwiet (retweeting) is wanneer `n twiet populêr is en ander gebruikers dit verder versprei. Beide twiets en hertwiets kan nagespeur word om te sien hoe dikwels dit gelees word. 

Gebruikers kan inskryf vir ander gebruikers se twiets – dit staan bekend as following en intekenaars staan bekend as followers  of tweeps. Gebruikers kan ook ander gebruikers blokkeer as hulle dit so verkies.

As `n gebruiker iemand wil antwoord of noem, word `n @-teken voor die persoon se gebruikersnaam gevoeg. Om `n twiet van `n ander Twitter-gebruik te deel met jou eie lesers, kan jy die retweet knoppie in die twiet self gebruik.

Whatsapp for you PCWhatsapp vir jou rekenaar

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. 

 

whatsappBaie van ons raak paniekbevange as ons buite selfoon of  WiF-ontvangs  is, terwyl ander op hul gelukkigste is in die middel van nerens met geen selfoontoring in sig. As jy in die eerste kategorie val, is jy waarskynlik ook `n geswore WhatsApp-gebruiker. 

Die goeie nuus is dat WhatsApp vanaf einde Januarie nie net op jou foon beskikbaar is nie, maar ook op jou tablet of rekenaar. Whatsapp Web gee aan gebruikers die gerief om gebruikers boodskappe te laat stuur en ontvang deur middel van `n webwerf.

Jou gesprekke sal ook outomaties gesinkroniseer word tussen Whatapp op jou selfoon en die toepassing op jou rekenaar.  Die enigste nadeel is dat dit slegs gebruik kan word met Google Chrome. As jy WhatsApp op jou rekenaar wil gebruik, kan jy die volledige instruksies op Cnet bekom.

Met die gemak en toeganklikheid van WhatsApp kom egter ook `n bietjie risiko. As jy gereeld Whatapp gebruik, kyk ook uit vir hierdie nuutste bedrogpogings.

 `n Nuwe WhatsApp Wangiri veldtog is tans in omloop waar gebruikers genoop word om `n internasionale oproep te maak wat gevolglik tot geweldige hoë kostes ly. 

Wangiri is `n tipe telefoonbedrog waar die skuldige lukrake nommers skakel en die foon neersit na een lui. `n Gemisde oproep wys dan op die ontvanger se foon. Die selfoongebruiker skakel terug omdat hy glo die oproep was vir hom bedoel en inderwaarheid skakel hy ‘n premium (en duur!) nommer.

WhatsApp-gebruikers kry `n boodskap met `n kontak aangeheg wat vra dat die “persoon” teruggebel word. Lees meer oor dié nuutste skema hier.

`n Tweede voorbeeld is `n SMS-veldtog kan WhatsApp-gebruikers R210-00 per maand uit die sak jaag. `n SMS word ontvang met die volgende bewoording word ontvang:

“You have not updated to the latest WhatsApp add-ons. Click here now [URL]. (Free MSG) 31655 optout dial 0110621424”. `n Skakel lei gebruikers na `n skerm met die boodskap “Update your wall 4 WhatsApp”.

Die fynskrif onderaan dui aan dat jy eintlik inskryf vir `n sosiale netwerk genaamd Buddiechat wat jou R7-00 per dag uit die sak gaan jaag. Gebruikers kliek onwetend op die skakel omdat hulle glo dis wettige WhatsApp-kommunikasie of omdat hulle in gedagte is.

Tune in to Bits & BytesSkakel in by 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!

Die afgelope September het ons een jaar op die lug gevier. Bits & Bytes het aanvanklik begin as `n nuusbrief vir personeel,  maar daar was net te veel interessante dinge om te deel – ons kon dit nie net vir onsself hou nie. Maar wat meer kon ons doen?

Die antwoord was maklik. Met `n gehoor van 30 000 luisteraars tussen die ouderdom van 14 en 28, het ons geweet MFM is die perfekte pasmaat. En so is Bits & Bytes, die radio-weergawe gebore. Vir die afgelope jaar het ons `n weeklikse insetsel gedurende die AM-PM-show om 11:45 Dinsdagoggende gehad met Tian Petersen as aanvanklike stem vir IT, maar mettertyd het Marc-Allen Johnson by die span aangesluit.

Bits & Bytes is nie nie bloot nog `n institusionele mondstuk wees nie, maar het mettertyd `n platform geword waar interessante tegnologiese verwikkelinge en speelgoed, bespreek kan word. Met elke insetsel probeer ons om `n kombinasie van relevante nuus vir studente en personeel, sowel as interessante verwikkelinge op die tegnologiese front op `n informele trant aan luisteraars oor te dra.

Ons besef egter dat almal nie toegang het om daarna te luister nie en het dus die fasiliteit geskep waar jy, nadat dit uitgesaai is, steeds aanlyn na die uitsendings kan luister. Al wat jy hoef te doen is om na WWW.SUN.AC.ZA/BB te gaan waar daar `n lys van alle vorige nuusbriewe is, maar ook al 34 vorige radio-uitsendings. Kliek bloot op die mp3-skakel.

Die insetsels word binne die US-netwerk gehuisves, dus gaan dit nie jou internetkoste opvreet nie – jy kan met `n geruste hart luister. As jy wel die regstreekse uitsending wil hoor, skakel gerus elke tweede Dinsdag om 11:45 op die AM to PM Show op MFM saam met Eduard en ons eie Tian en Marc-Allen in. Kliek HIER om aanlyn na MFM te luister.

Jy is ook welkom om kommentaar en vrae in daardie tydsgleuf via Twitter aan ons te stuur en indien daar geleentheid is, sal Tian dit op die lug beantwoord. Tweet ons by @ITStellenUni!

So what do we really do?So wat doen ons nou eintlik?

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.

servicecatMeeste van die tyd word IT beskou as die mense “wat rekenaars regmaak” of die e-pos of internet moet regmaak. Dis ook waar, maar, soos `n ysberg, is daar meer onder die oppervlak.

Om vir al ons gebruikers `n beter prentjie te teken van al die dienste waarmee IT-personeel hulself deur die jaar besighou, het ons `n gebruikersvriendelike (ons glo so!) dienskatalogus saamgestel in die vorm van `n webwerf.

Die katalogus bevat al ons dienste – die waarvan jy reeds weet en `n hele klompie onbekendes. Buiten `n volledige beskrywing van elke diens, verskaf ons instruksies oor hoe om daarvoor aansoek te doen, watter tye dit beskikbaar is en wie om te kontak as jy meer inligting daaroor wil hê.

Ons het ook `n handige A-Z funksie ingebou, `n webwerfkaart en skakels na al ons ander relevante hulpmiddele. `n Webgedeelte wat al ons nuutste bloginskrywings en nuus wys, sowel as `n lewendige Twitter-voer sal sorg dat jy op datum is met alles wat daar te weet is by IT.

Ons is natuurlik nuuskierig om te weet wat jy daarvan dink, so gaan kyk asb. by www.sun.ac.za/itservices en laat ons weet.

As jy enige voorstelle of kommentaar, goed of sleg, het, stuur vir ons `n e-pos by helpinfo@sun.ac.za. `n Terugvoer skakel en kontakknoppie is ook onderaan die dienskatalogus beskikbaar vir vinnige toegang.

Would you be able to disconnect?Sal jy kan afskakel?

Friday, October 24th, 2014

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.

Volgens sielkundige en neuro-wetenskaplike Sean Luo van die Universiteit van Columbia, weerspieël 3.7 tot 13 persent van Amerika en 10 persent van Suid-Korea se internetgebruikers simptome van internetverslawing of ontoepalike internetgebruik. (http://www.cbsnews.com/news/how-real-a-risk-is-social-media-addiction/) In China is rehabilitasiekampe vir internetverslaafdes reeds `n algemene verskynsel. Algemene bewuswording rondom internet en sosiale media verslawing is gelukkig ook aan die toeneem.

Verlede week is berig dat dokters `n man opgeneem het in die Amerikaanse vloot se middelmisbruik-program vir sy verslawing aan Google Glass. Hy het die kopstuk vir tot 18 ure per dag gedra en wanneer dit verwyder word, ernstige onttrekkingsimptome ervaar. Self as hy dit nié gedra het nie, het hy kompulsief sy regterslaap, waar die toestel normaalweg geaktiveer word, getik. Hy is gevolglik gediagnoseer met IAD (Internet Addiction Disorder)

Dis egter nie `n nuwe verskynsel nie. Reeds is 1996, kort nadat die internet ons lewens betree het, is internetverslawing reeds herken as `n moontlike psigiatriese afwyking. Selfs al is dit nie amptelik opgeneem in die nuutste DSM(Diagnostic and Statistical Manual of Mental Disorders)-handleiding, wat gebruik word deur psigiaters nie, behoort dit te wees volgens kenners. Psigiaters verkies ook die term PUI (Problematic Internet Use bo die gebruik van die woord “verslawing”. PUI verwys na die buitengewone hoë gebruik van rekenaars in so `n mate dat dit inbraak maak om `n persoon se daaglikse lewe.

Die diagnose vir internetverslawing is nie `n maklike een nie, aangesien iemand nie verslaaf raak aan die medium self nie, maar eerder aan die beskikbare aanlyn-inhoud. Die internet is slegs die platform daarvoor. Daar word ook beweer dat IAD bloot `n simptoom is vir ander onderliggende afwykings eerder as een op sy eie. Vele ander verwante verslawings val onder die algemene IA-term, byvoorbeeld dobbelverslawing, verslawing aan internetverhoudings, aanlyn inkopies, ens. (meer detail oor IAD kan gevind word op www.wikipedia.org)

Sou jy kon afskakel, selfs net vir `n dag? Wat van dié naweek sonder Facebook, Twitter of e-pos? Dink net hoeveel tyd sal jy hê vir ander aktiwiteite …

In 2013 het Paul Miller, `n Amerikaanse joernalis van Springfield, Missouri en senior-redakteur van The Verge besluit om af te skakel van die altyd-verbinde aanlyn wêreld waarin hy hom bevind het. Sy doel was om “homself te vind” en meer produktief te wees. Hy’t homself afgesny van die internet te gebruik, ophou sosiale media gebruik en teruggegaan na `n wêreld voor internet, toepassings en slimfone. Jy kan sy praatjie hieronder kyk en hoor hoe sy ervaring was.
