Still missing out on the new SU website?

Friday, April 26th, 2013

On Monday when we browsed to www.sun.ac.za, most of us were met with a fresh new Stellenbosch University web site.  For those of you who still haven’t managed to see what the fuss is about, here’s how to fix that. (Read more on the new site)

Each time you access a page through your web browser, the browser caches (i.e., stores) it locally. The browser does this to reduce bandwidth usage, server load and also to load pages faster.

By doing this, the browser doesn’t have to newly retrieve files or images from the remote web site each time. As convenient as this is, it also means that if you do not clean your browser’s cache, you might miss out on new information and any changes on websites. 

If, after Monday’s changes to the university’s homepage, you are experiencing problems accessing the new sun page or any other sun web pages, we suggest you clear your browser’s cache.

Below you’ll find instructions on how to do this, depending on the browser you use.

The big drive in the sky

Friday, April 12th, 2013

Last year we told you more about cloud storage, what it is and the multitude of options available to you. (read the articles here) If you haven’t taken the virtual leap yet, we have even more information for you to digest. This time we have a closer look at one of those options, Microsoft’s Skydrive.

What is SkyDrive?

SkyDrive is a file hosting service that allows users to upload and sync files to a cloud storage and then access them from a Web browser or their local device. 

What does SkyDrive offer me?

The service offers 7 GB of free storage and additional storage is available for purchase. Files of up to 300 MB can be uploaded via drag and drop into the web browser, or up to 2 GB via the SkyDrive desktop application for Microsoft Windows and OS X.

With the SkyDrive desktop application for Windows or Mac, your files on SkyDrive are available online or offline and update automatically across your devices. You can also access your SkyDrive using a brand new app for Android v2.3 or the updated apps for Windows Phone, iPhone, and iPad.

The Office apps (Word, Excel, etc.) let you save your documents by default into your SkyDrive directory on your local computer. With the help of SkyDrive, those files are synchronized with the files in your SkyDrive cloud storage, letting you access them from anywhere, or edit them using the online Web version of Microsoft Office.

Online collaboration is made easy with the new  Office Web apps, including Excel forms, co-authoring in PowerPoint and embedable Word documents. Microsoft added Office Web Apps support to SkyDrive allowing users to upload, create, edit, and share Microsoft Office documents directly within a Web browser.

You can share documents with other people, which provides them with a link to access the documents from their own SkyDrive account. From there, the other people can make changes to the documents at the same time that you’re changing them. As you’re working, you’ll see the areas you’re changing. Then when you save, your document will receive the updates from the other person before saving. If there are any conflicts, you’ll be notified of them and given a chance to fix them. 

 

When users delete any files on SkyDrive, the service will allow the user to undo the action and restore the deleted file from the recycle bin back to the original folder.  All items stored in the recycle bin are kept for a minimum of 3 days and a maximum of 30 days.

SkyDrive integrates with social networks such as FacebookTwitter and LinkedIn to enable users to quickly share their files with their contacts on these social networks. It also supports geo-location data for photos uploaded onto the service, and will automatically display a map of the tagged location. SkyDrive also allows users to tag people on the photos uploaded onto the service via the web interface or via Windows Photo Gallery.

Additionally you can sort files, change file views, view photo slide shows, and stream video.  All this functionality in one place, safe up in the clouds.

It’s all about meme

Friday, April 12th, 2013

Years ago it was the dancing baby, now it’s the Harlem Shake. These silly & sometimes shocking internet video clips are called meme’s and they’re just as entertaining and random as their live siblings, flashmobs. 

A meme is a phenomenon spreading via the internet and can take on various forms – images (for example the Grumpy Cat and Lol cats photos), video, hashtags, websites or a simple work or phrase. 

The word memes was originally coined by evolusionary biologist Richard Dawkins in his 1976 book The Selfish Gene. The word originated from the Greek word  ”mimema” (which means “something imitated”). Dawkins described memes as a form of cultural propaganda, a means for people to communicate social memories and cultural ideas to each other. Memes spread organically and just like evolutionary biology, they include mutations and duplications. They spread fast and very rapidly change into different, new versions. People see the original, imitate and change it, and then distribute the new version on the internet. 

Telling examples include the dancing baby, dating from 1996, and possibly also one of the first well-known memes. Recently the internet was invaded by the notorious Harlem Shake, a meme that even featuring during a Varsity Cup match.

Came across any interesting memes? Let us know!

Update on SEACOM internet connection

Friday, April 5th, 2013

On 26 March 2013, we let you know about the damage to the SEACOM undersea cable caused by a ship’s anchor off the coast of Egypt and how the speed of Internet browsing has been affected for the entire university. Since then internet traffic to South Africa (including the university network) was rerouted to alternative routes until the undersea cables were repaired. This will mean the Internet browsing and speed will be slower than normal. 

Since then there were reports of 3 divers that were caught by the Egyptian coast guard cutting undersea cables in an act of sabotage. There has been no confirmation if the SEACOM cables were targeted or affected by the sabotage. [http://www.infoworld.com/d/networking/sabotage-suspected-in-egypt-submarine-cable-cut-215376] 

A undersea cable repair ship has been dispatched and the estimated time to repair the damage is approximately 15 April, since sea conditions and the extent of the cable damage have to be assessed. Internet will be slow until next week. Local network services like Webmail, WebCT and Blackboard are not affected, but overseas-based services like Turnitin, Gmail, Google searches and the browsing of library databases, based overseas, will be slower than usual.

Lower internet rates and faster internet

Wednesday, February 6th, 2013

Thanks to the University’s collaboration with SANREN and the implementation of the new Fortigate firewall, users on campus can now look forward to lower internet rates and faster, more stable internet. Both these projects were necessary if one takes into consideration that the university’s bandwidth usage doubled each year for the past 8 years. In spite of the increase in usage, rates were never increased. 

 

RATES FOR INTERNET USAGE FROM 1 JANUARY 2013

Tariff A @R0.02: Monday-Friday: 08h00-23h59 

Tariff B @ R0.01 : Monday-Friday: 00h00-07h59, as well as Saturdays and Sundays 

 

Take note that the relevant tariff is determined by the day and time the download process was completed. 

•Example 1: If you start downloading a file of 3 MB at 16:55 on Monday and the download is completed at 17:10 (Monday), the tariff for Monday 17:10 will apply. 

•Example 2: If the same file is downloaded from Monday 07:55 to Monday 08:10, the tariff for Monday 08:10 will apply.
