Internet

Need for speed?

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.

Money gone phishing?

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.

What To Do When The Internet Is Down?

Let the search 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.

Did you know?

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.
