Time to retire IE6

09 Mar

Internet Explorer 6 is now ten years old and yet almost one in four of people using Internet Explorer are still using that version.

We read about exciting new technologies such as CSS3 with its gradient and shadow commands, HTML5 with its animation and video tags and yet many users cannot take advantage of them. Moreover, web designers keep having to compromise their designs just to render their pages in IE6.

Microsoft have put together a site called ‘The Internet Explorer 6 Countdown‘ site to try and encourage people to leave the ancient browser behind and start using the latest standards comliant IE9

We wish them all success in retiring the old browser.

Wonderwheel and teachmeet

13 Feb

This is something we picked up from one of the teachmeet events (TES Article).

(here is a recorded teachmeet video).

It is a Google feature that has been around since 2009 and yet we did not know about.

You know the situation – you ask a student to do some homework on a fairly generic subject  such as ‘computing’. So they go into Google and type in the search term ‘computing’.

Result: 149 million hits.

Now one option is to use the ‘Advanced’ feature to refine the result. But did you know about the ‘wonder wheel’?

Open Google with Firefox and enter the search term ‘computing’.  As well as the usual list of hits, notice the items on the left hand side that include the clip below

Click on the ‘Wonder Wheel’ option and a mind map type of graphic appears that shows related search results. The student can then click on the branches to find more specialised results. It certainly seems a more user-friendly way of searching than the l boolean and other filtering methods of Advanced search.

Here is a Wonder Wheel of computing

Could the Internet be shut down in the West?

07 Feb

Unless you have been on holday on a desert island (I wish), you cannot have missed the 24 hours media coverage of the developments in Egypt.

Notwithstanding the political developments, what has become apparent is that the Internet in Egypt was shut down for some days.

But could a government, say the USA, shut down the Internet? The answer seems to be yes. And plans are afoot to make it law that it is able to do so.

 

In Egypt, there are only a handful of ISPs and it seems they were told to effectively re-program their main routers so no IP traffic could find its way into the country. Traffic is directed through a router by a protocol called ‘Border Gateway Protocol’ or BGP. A quick change to the routers and the country became an Internet black hole.

Senators in the States are now pushing for legislation to have their own  ‘Internet off switch’, one that may give their government authority over privately owned computer systems.  Is this a good thing?

There has been such a furore over civil liberties that a statement has been issued to refute the implication.

It seems the Internet is now right at the centre of our democratic process in the West.

This could be a topic of discussion when discussing Society and ICT.

 

How digital learning is changing America

26 Oct

America have embraced a concept of school called a ‘charter school’ or ‘schools of choice’. This is very much like the new Academies in the UK. They are publicly funded schools but are largely free of state laws and district regulations.

USA flag

Now these schools are looking to online learning in order to improve performance even further. Online learning is growing by 30% annually in the USA. There will be a move away from the traditional text book and more effort will go into personalised digital learning profiles for each student. This will be a blend of online and offline learning resources.

After all, a netbook or tablet PC is now cheaper than a set of textbooks. It is time for education both home and abroad to embrace the opportunities afforded by digital online resources and embed them in the fabric of education.

Google ponders on the social Internet

19 Oct

The search giant Google is recognising a new trend on the Internet, namely that people tend to ask their online friends for advice rather than look to a search engine. For the first time according to comScore, people spent more time on Facebook than on Google sites.

The problem for Google is that fundamentally what really matters to advertisers is how many people see their ads, wherever people gather, that is where the money is going to be.

Read here for the New York Times article

For example, they turn to their Facebook friends and ask questions such as ‘Can you recommend a good baby sitter” or “I fancy going to a new restaurant – any recommendations?”.

You can see how difficult this kind of question can be for a search engine because it involves a value judgement and local knowledge.

This is an interesting case study of how people change the way they use technology and suddenly the market leader has to change the way they do things – can they do that or is the culture too ingrained to be able to change? Time will tell.

So is this the new trend? Will Facebook become the new search engine for complex questions?

Will physical and virtual life blur?

12 Oct

I was recently pondering the further blurring of the line between our life in the physical domain and our life online. Is there a distinction any more? Is an online friend whom you have never met any less valid than your best buddy?

Back in the day (around the 1980′s) I was exploring this thing called the Internet with a Hayes smartmodem running at 300 baud. At the time there was CompuServe providing a walled garden online experience and in the wilds you could visit text based bulletin boards. I could even indulge in a bit of text based MUDs for entertainment and some creative of ASCII art to fulfil the artist in me.

So at that time there was a clear on-line / off line life. Then two decades or so later there was ‘cyber’ this and ‘e-’ that cropping up in the media, which is now starting to sound quaint, like your old uncle calling the DAB radio in the kitchen a ‘wireless’.

Wind forward to today and it is a completely different ball game. Milllions are happily playing on-line, perhaps connected to a World of Warcraft server and a real-time audio server such as Ventrillo so a group of you can chat away for a bit of escapism and goblin bashing.

Even politicians are recognising that the internet is becoming as vital as water as a basic resource. And they have a point. I was recently unable to go online at home due to a wonky telephone connection and it was not a pleasant experience. No banking, no gaming, no social networking, no blogging, no research. I even had to dig out my old CDs from the attic as the music service streaming into my living room no longer worked.

Hollywood are also recognising the concept with its recent Bruce Willis film Surrogates where they reverse the concept of avatar and physical presence.

Let’s move on a few years when I think the lines will blur even more. Consider augmented reality. Devices will be available that overlay on-line data with what you see.

In a recent BBC interview with the SF author William Gibson opined that our grandchildren will see no distinction between on-line and off-line. He has a point.

 

Hackers target Xbox Live players

21 Feb

halo3

Many of us are competitive in nature and like to win when we are playing against someone else.  But how far would you go to ensure that you won?

For those people playing Halo 3 on the Xbox Live, it seems that you can go all out to get your revenge on someone who has beaten you in a game.

A team of hackers have started to sell a ‘service’ that finds your opponent’s IP address, launches a denial of service attack and effectively blocks them out of the game for a period of time.

Spreading the message through viral advertising

20 Feb

cadburys_viral

Have you seen the latest advert from Cadburys?  If you somehow seem to have missed it, you really need to go and take a look.  I still giggle every single time I watch it.

Of late, Cadburys have come up with a range of hugely successful, award winning adverts which, on the surface, have absolutely nothing to do with chocolate.  It all started with the drumming gorilla – you can’t possibly have failed to have seen that particluar one.

So, if these adverts don’t mention or even show the actual product, how on earth have they been so successful?  Well the answer is viral marketing.

Italy police warn of Skype threat

15 Feb

skype

In the past many crimes might have been planned down the local pub, but there was always the risk of the conversation being overheard by the wrong person.  Then came the mobile phone which provided an easy method to contact accomplices any time, any place.  But the police made this a less than desirable method of communication with the abiltiy to wire tap calls and obtain complete transcripts from phone companies.

Never let it be said that criminals aren’t able to adapt to new technology.  It seems that many are now using Skype to contact one another over the internet, because as yet, all calls remain encrypted and inaccessible to the police.

Snow strains technology networks

03 Feb

snow

How many of you were lucky enough to be sent home from work because of the snow?  I think I was almost as excited as the students to be told that we could pack up and go home for the rest of the day.  To be honest, I hadn’t managed to get an awful lot done in lessons as the main focus of everyone’s attention seemed to be what was going on outside the windows.

No matter what happens in our daily lives, we expect the internet to be working and we automatically assume that websites will be there when we need them.  But for many people who woke up yesterday to see a blanket of snow  this wasn’t the case.  They did exactly what you would expect, they tried to  check the travel websites to find out about road conditions and see if public transport was running.  However, when they most needed the information, many found that it wasn’t available as websites started crashing.

National Rail Enquiries said that website hits were up 800% compared to a normal Monday morning.  At its height, more than 32,000 users were trying to access pages every second.  National Rail Enquiries were lucky, although their site was running more slowly than normal, it did remain available.  However, many other sites, for example, Transport for London (TfL) weren’t able to cope and they crashed under the abnormally heavy demand.

Websites weren’t the only casualty of the snow, mobile phone networks also buckled under the strain from the sheer volume of calls as people tried to contact family, friends and work colleagues.  Many reported problems making calls due to network congestion.  T-Mobile said that there were 73% more calls than normal during the morning.

As many people decided to stay at home rather than travel in the hazardous conditions there was also an increase of 20% in the demand for broadband.
