Need for speed?Soek jy spoed?

Friday, May 25th, 2012

We always need more time and want to do everything faster. To find something fast on the internet is just one way to save time.

Here are a few fast ways to make sure you get the most out of your browser’s functionality.

1. Use a fast browser

Fairly obvious isn’t it? In a previous article we looked at the various browsers and their performance. By now you know that all browsers are faster than others and Google Chrome is currently winning the race when it comes to speed.

2. Disable Flash

Flash websites are all over the web and extremely popular. Although they look impressive, they also slow down your browsing experience considerably. Rather turn off Flash by default and reactivate it when you really want to see the Flash animations. Some browsers require an add-on to block Flash. For Chrome, you need the extension Flashblock. There’s also a Flashblock extension for Firefox. Internet Explorer has a built-in tool you can access by clicking Tools | Manage Add-ons.

3. Get rid of all those toolbars

More toolbars, slower speed. As simple as that. And do you really need all those toolbars? Some toolbars take up computer memory while others are eating away on your bandwidth and sending and receiving data in the background. (and you thought they were just sitting there doing nothing!)

4. Use tabs, not windows

Too many tabs can cause problems, but they’re very handy when it comes to browsing efficiency. How do tabs speed up your experience? The first is all about organization. With multiple tabs in a single window, it becomes quite a bit faster to locate the page you need to work on. You don’t have to maximize a window, discover that it’s not the right one, minimize it, maximize a new window… until you find the correct one. A single window open with multiple tabs is far easier to search. This is not the only way tabs can help you. Browsers like Chrome treat each tab as an individual process (instead of a child process of a parent). So when a Web site causes a tab to crash, you can close that one tab and not lose all the other tabs. This behavior is not a standard at the moment, so you’ll need to switch over to the Chrome browser to take advantage of it.

Ons is altyd op soek na meer tyd en wil alles vinniger doen. Om vinniger iets op die internet op te spoor is een opsie.

Hier is `n paar slim idees om seker te maak jy kry die beste spoed moontlik uit jou webblaaier se funksionaliteit.

1. Gebruik `n vinnige webblaaier

Redelik voor die hand liggend is dit nie? In ons vorige artikel oor die verskeie webblaaiers het ons vinnig gekyk na spoed en hoe blaaiers vergelyk. Julle weet dus al teen die tyd dat sommiges vinniger as ander is. Google Chrome is tans voor as dit by spoed kom.

2. Deaktiveer Flash

Daar is geweldig baie Flash webwerwe op die internet en alhoewel dit redelik indrukwekkend lyk, maak dit jou vermoeë om vinnig te blaai aansienlik moeiliker.

As spoed vir jou belangrik is, sit eerder Flash af onder jou webblaaier verstellings en aktiveer dit as jy regtig die Flash animasie wil sien. Met sommige blaaiers het jy addisionele applikasies nodig soos Flashblock, maar Internet Explorer het `n ingeboude opsie onder “Tools” hiervoor.

3. Raak ontslae van jou nutsbalke (“toolbars”)

Hoe meer nutsbalke jy versamel in jou webblaaier, hoe stadig gaan jou internet wees. So eenvoudig soos dit. En het jy regtig alles nodig? Sommiges gebruik geheue terwyl ander stilweg jou bandwydte opvreet deur data te stuur en ontvang in die agtergrond. (en jy het gedink hulle sit net daar en niks doen nie.)

5. Gebruik oortjies (“tabs”) in plaas van nuwe vensters

Te veel oortjies kan verwarrend raak, maar hulle is steeds die beste opsie om jou webblaaier so doeltreffend moontlik te maak. So hoe help dit? Met meer as een oortjie in een venster, is dit baie vinniger en makliker om die bladsy waaraan jy wil werk, te sien. Jy hoef nie `n ander venster groter te maak, besef dit die verkeerde een, `n ander een oop te maak en voort te sukkel nie.

Webblaaiers soos Chrome hanteer ook elke oortjie soos `n aparte proses. So wanneer `n webwerf een oortjie laat toegaan, verloor jy net daardie een webwerf, nie almal waaraan jy gewerk het nie.

Money gone phishing?Slagoffer van strikrowery?

Friday, May 11th, 2012

The second you connect to the internet you put yourself at risk. Scary thought, but we tend to forget just how vulnerable we are and the easy targets we become when we’re not careful about our safety on the internet.

As an internet user you expose yourself on a daily basis to malicious software and the possibility of data theft. This includes phishing. Phishing scams use bogus e-mails and Web sites that seem legitimate but are actually designed to trick users into revealing personal and financial information. Computer criminals can then use the data to spy on or blackmail users, hijack their online accounts (including bank accounts), spread rumors, or operate under the victim’s identity.

According to our local Stellenbosch ABSA branch there are still some Stellenbosch University staff who fall prey to cybercriminals by clicking on phishing emails. To make sure you don’t become a victim, read more on phishing on IT’s self help wiki.

Die oomblik wanneer jy aanlyn is, loop jy sekere risikos. Dit klink miskien oordrewe, maar ons is geneig om te vergeet hoe blootgestel en watter maklike teikens ons is vir kuberkriminele as ons nie bedag is op ons aanlynveiligheid nie.

As `n internetgebruiker stel jy jou daagliks bloot aan kwaadaardige sagteware en die moontlikheid van datadiefstal. Dit sluit kuberstrikroof (“phishing”) in. Hierdie tipe elektroniese rooftogte gebruik skelm e-posse en webwerwe wat wettig lyk, maar eintlik so opgestel is om gebruikers te mislei sodat hulle persoonlike en finansiële inligting onthul. Kuberkriminele gebruik dan die data om, onder andere, toegang te kry tot aanlynrekeninge (insluitende bankrekeninge) of die persoon se identiteit oor te neem.

Volgens die plaaslike Stellenbosch ABSA-tak is daar steeds Stellenbosch Universiteit personeel wat in die slaggat val en slagoffers word van kuberkriminele deur op “phishing” e-posse te kliek. Om seker te maak jy word nie een van hulle nie, lees meer oor “phishing” op IT se selfhelp wiki.

Let the search begin!Laat die soektog begin!

Friday, May 4th, 2012

Have you ever tried looking for something on a search engine only to get 1267 results totally unrelated to your initial query?

Internet search engines have the ability to search through a huge amount of web pages by means of titles, key words or text. But to find the correct results fast and effectively, you need to know how to use search engines to your advantage.

We’ve compiled a few basic hints to help you with your searches.

– Use more than one keyword

On average most people use 1.5 words per search – not enough for a successful search. The suggested amount of words are 6 to 8, preferably nouns. Articles and pronouns are mostly ignored by search engines. Avoid verbs and adjectives unless it helps to define the topic.

– Use phrases

A phrase is a combination of one or more words found in the exact order in the text you’re looking for. Make sure you use quotation marks, for example “get results fast”.

– Caps and punctuation

Most search engines are sensitive to case. However if you use small caps, most search engines will recognise both capital letters and small caps. To play it safe, rather use small caps.

– Boolean searches

The “Boolean” search was named after George Boole, a 19th century mathematician. A Boolean search is a handy took which gives the best results for a search. The three most used options are AND, OR and AND NOT.

AND means you’re looking for documents containing both/all words. For example if you serach for “search engines” AND “Google” AND “Boolean”, you will get results containing all three words.

OR means you’re looking for results containing one of the two words – it doesn’t matter which one. Preferably use synonyms for this option. For example “small caps” OR “lower case”.

AND NOT means you are looking for results containing one word, but not if the document also contains another word. The search for “Google” AND “search engines” AND NOT “Boolean” will give you all the documents with “Google en “search engines”, but they won’t have “Boolean”.

Most search engines support the AND NOT option, but they sometimes use the words BUT NOT or NOT instead. In these cases they are indicated by placing a minus in front of the word or phrase.

– Take note of your spelling and also consider the alternative spelling of words.

– Use specific words/phrases rather than generic categories. Rather search for “laptop” than “computer”.

– Only search one specific website or domain. To do this, type the subject you’re looking for, followed by “site:” and the webaddress. (For example inetkey site:www.sun.ac.za/infoteg)

– Use a specialist search engine, for example an image search engine to search for your images and photos. Many websites have their own subcategories which makes it easier to conduct a serach. Wikipedia has a very extensive list of specialist search engines.

Just remember there are between 200 and 800 million documents online! Refine your search as much as possible and you’ll be guaranteed better results.

Rumour has Amazon became the number one online shopping website before Google existed because Yahoo listed all the sites in their directory alphabetically! Luckily times have changed.

For more about the various search engines, how they work and tips, read more on Search Engine Watch.

Het jy al ooit `n soektog gedoen op `n soekenjin net om 1267 resultate te kry wat niks te doen het met wat jy in die eerste plek gesoek het nie?

Internetsoekenjins beskik oor die vermoeë om `n geweldige groot hoeveelheid webbladsye te deursoek deur van titels, sleutelwoorde of teks gebruik te maak. Maar om die regte resultate vinnig en effektief te lewer, moet jy weet hoe om dit optimaal te benut.

Ons het `n paar basiese wenke saamgestel om dit makliker te maak vir jou.

– Kies meer as een sleutelwoord

Die meeste mense gebruik 1.5 woorde per soektog en dis nie genoeg vir `n suksesvolle soektog nie. Die aanbevole aantal woorde is 6 tot 8, verkieslik selfstandige naamwoorde. Lidwoorde en voornaamwoorde word geignoreer deur soekenjins.Vermy werkwoorde en byvoeglike naamwoorde behalwe as dit die onderwerp beter definieer.

– Gebruik frases

Frases is kombinasies van twee of meer woorde wat in die presiese volgorde in die teks wat jy soek gevind kan word. Maak seker jy sit die frase in aanhalingstekens, byvoorbeeld “regte resultate vinnig”.

– Hoofletters en leestekens

Die meeste soekenjins is sensitief as dit kom by kas. As jy kleinletters gebruik word sal die meeste soekenjins egter beide hoofletters en kleinletters raaksien. Kleinletters is dus jou veiligste opsie.

– Booleansoektogte

“Boolean” soektogte is vernoem na George Boole, `n 19de eeuse wiskundige. `n Boolean-soektog is `n handige hulpmiddel wat die beste soekresultate lewer. Die drie algemeenste Boolean-opsies is AND, OR en AND NOT.

AND beteken jy soek net dokumente wat beide/albei woorde bevat. Byvoorbeeld as jy “search engines” AND “Google” AND “Boolean” kies, sal jy slegs resultate kry wat al drie woorde bevat.

OR beteken jy soek resultate wat een van die twee woorde bevat – dit maak nie saak watter een nie. Gebruik verkieslik sinonieme vir hierdie opsie. Byvoorbeeld “small caps” OR “lower case”.

AND NOT beteken jy soek resultate wat een word bevat, maar nie as die dokument ook `n spesifieke ander word bevat nie. Die soektog “Google” AND “search engines” AND NOT “Boolean” sal dus slegs vir jou die dokumente gee met “Google en “search engines”, maar nie “Boolean” ook in het nie.

Die meeste soekenjins ondersteun die AND NOT-opsie, maar soms word dit ook BUT NOT of NOT genoem. In hierdie gevalle word dit aangedui deur `n minusteken voor die word of frase te plaas.

– Let op jou spelling en oorweeg ook alternatiewe spelling van woorde.

– Gebruik spesifieke woorde eerder as generiese kategorieë. Soek eerder “skootrekenaar” as “rekenaars”.

– Soek slegs op `n spesifieke webwerf of domein. Om dit te doen tik die frase wat jy soek, gevolg deur “site:” en die webwerfadres. (Byvoorbeeld inetkey site:www.sun.ac.za/infoteg)

– Gebruik `n spesialis-soekenjin, soos `n beeld(“image”)-soekenjin, om fotos en prentjies te soek. Baie webwerwe het ook hulle eie spesiale onderafdelings waaronder jy kan soek. Wikipedia het ook `n baie volledige lys oor spesialis soekenjins.

Onthou daar is tussen 200 en 800 miljoen dokumente aanlyn! Hoe beter jy jou soektog definieer, hoe meer tyd gaan jy spaar.

Volgens oorlewering het Amazon die nommer een aankope-webwerf geword omdat Yahoo destyds voordat Google bestaan het, al die webwerwe in hulle gids alfabeties gelys het! Gelukkig het tye verander.

Did you know?Het jy geweet?

You could fit the whole Internet on just 200 million Blu-Ray disks and the first webcam was used to monitor a coffee maker?

The technology behind the Internet began back in the 1960′s at MIT. The first message ever to be transmitted was LOG. Why? The user had attempted to type LOGIN, but the network crashed after the enormous load of data of the letter G. It was to be a while before Facebook would be developed…

The Internet began as a single page at the URL http://info.cern.ch/hypertext/WWW/TheProject.html, which contained information about this new-fangled “WorldWideWeb” project, and how you too could make a hypertext page full of wonderful hyperlinks. Sadly, the original page was never saved, but you can view it after 2 years of revisions here.

Other interesting internet trivia:

The first webcam was deployed at Cambridge University computer lab – its sole purpose to monitor a particular coffee maker and hence avoid wasted trips to an empty pot.
Although the MP3 standard was invented in 1991, it wouldn’t be until 1998 that the first music file-sharing service Napster, would go live, and change the way the Internet was used forever.
Ever since the birth of the Internet, file sharing was a problem for the authorities that managed it. In 1989, McGill University shut down their FTP indexing site after finding out that it was responsible for half of the Internet traffic from America into Canada. Fortunately, a number of similar file indexing sites had already been made.
Sound familiar? Even today file sharing dominates Internet traffic with torrent files accounting for over 50% of upstream bandwidth. However, a larger proportion of download bandwidth is taken up by streaming media services such as Netflix.
Google estimates that the Internet today contains about 5 million terabytes of data (1TB = 1,000GB), and claims it has only indexed a paltry 0.04% of it all! You could fit the whole Internet on just 200 million Blu-Ray disks.
Twenty hours of video from around the world are uploaded to YouTube every minute. The first ever YouTube video was uploaded on April 23rd 2005,by Jawed Karim (one of the founders of the site) and was 18 seconds long, entitled “Me at the zoo”. It was quite boring, as is 99% of the content on YouTube today.

Jy kan die hele internet op 200 miljoen Blu-Ray skywe stoor en dat die heel eerste webkamera gebruik is om `n koffiepot te monitor? Deesdae is ons al so bederf met die internet dat dit moeilik is om `n lewe daarsonder in te dink. Maar weet jy waar dit alles begin het?

Die tegnologie agter die internet is alreeds in die sestigerjare by MIT (Massachusetts Institute of Technology) begin. Die eerste boodskap wat ooit gestuur het, het net een word bevat – LOG. Hoekom? Die person wat dit getik het, het LOGIN probeer tik, maar die geweldige hoeveelheid data wat die letter G bevat het, het die hele netwerk laat platval.

Die internet was oorspronklik net een bladsy by die URL http://info.cern.ch/hypertext/WWW/TheProject.html. Op hierdie enkele blad was `n opsomming oor hierdie nuwe projek wat die “WorldWideWeb” genoem word en hoe jy ook `n bladsy kan maak vol wonderlike hiperskakels. Ongelukkig is die oorspronklike blad nie meer beskikbaar nie, maar jy kan die hersiende weergawe hier kry.

Nog interessante internet-trivia:

Die eerste webkamera is implementeer in Cambridge se rekenaarlaboratorium – sy enigste doel was om een spesifieke koffiemasjien te monitor sodat die koffiedrinkers nie verniet loop en `n leë koffiepot kry nie. Hierdie “gevorderde” tegnologie word steeds selfs op ons eie kampus gebruik in sekere laboratoriums.
MP3’s is reeds in 1991 uitgevind, maar is eers in 1998 vir die eerste keer gebruik te danke aan Napster.
Reg van die begin af was het die deel van leêrs op die internet vir owerhede problem geskep. In 1989 moes die Universiteit van McGill hulle ftp-webwerf afsit nadat hulle besef het dis verantwoordelik vir die helfte van alle internetverkeer van Amerika na Kanada.
Die enorme omvang van die leêrdeling vandag met die gepaardgaande etiese kwessies kom dus al `n lang pad. Torrent-leêrs gebruik meer as 50% van die bandwydte van die internet – `n groot gedeelte word egter opgeneem deur videostrome van dienste soos Netflix.
Google beraam dat die internet vandag uit 5 million terabytes se data (1TB = 1,000GB) bestaan, waarvan Google self nog net 0.04% geindekseer het.
Twintig ure se videomateriaal word elke minuut van reg oor die wêreld op YouTube gelaai. Die heel eerste YouTube video is op 23 April deur Jawed Karim (een van die stigterslede van die webwerf) gelaai, was 18 sekondes lank en geweldig vervelig. (Sommige goed verander nooi!)
