Unfortunately this is no longer true. In the wake of recent islamist attacks, it is now routine to seen armed police patrolling around cities.

If the transformations/transitions are handled by the graphics card the faster js becomes irrelevant. For example js performance on IPad is not amazing, but it will run many transitions smoothly.

As far as WebGL, it clearly is important for any serious 3d. But adding a slight 3d effect to a UI element should not require a detailed knowledge of shaders and 3d geometry.

You make a fair point, but learning Italian or Portugese after Spanish is easy because they all share the same root language Latin.

An eastern language such as mandarin won't be much easier because you have learnt a second European language.

Computer languages have much more in common and have often copied earlier programming languages.

The language in the browser is not the problem to me. If I could use python it wouldn't change the fact that you still need to deal with the DOM, CSS and browser differences.

Hi posted this earlier, but it didn't get any traction. I guess the people here might be interested.

Brilliant!

Celsius please, or at least have both.This is supposed to be science not a localised weather report.

Just finished porting a javascript fractal tree generator, the javascript version is at

and the code to run in codify is in the textarea (small)

I wonder what effect this could have on the local climate. Pumping out hot air into cool air at height of 800 metres has got to have some affect.

Now if the base is used area is used for growing plants then the air emitted at the top would be moist, which I imagine would cause cloud formation as it meets the cold air.

Actually I have been using a similar technique for the last six months. However 30mins intervals and I only do it on days when I feel tired or unmotivated.

At the end of the period I go for a walk, or on an exercise bike for 5-10 mins. The best part is physically leaving the computer stop the eyes getting tired and drifting into a zombie state of zero productivity.

When I start a session I usually jot down a particular task to work on and review at the end. It does not guarantee productivity, but the short periods with reviews helps keep focus.

Clarifies that you will be paying per instance hour, instead of cpu.

Nothing is in concrete yet, if there is enough outrage amongst users maybe they will change their tune.

The latest attempt in the UK to deal with the problem

This is not exactly shocking. The quality of education has to be a factor as well. I am sure for most people an hour of one on one tuition, is more effective than a number of hours in a large class. Even more so if the rest in the large class are not interested in learning.

I was blown away by the google IO session. The idea of writing a game in Java and then having it converted to multiple formats, javascript/canvas/webgl, flash, android.

Quite amazing!

If they could add conversion to run on apple devices then this could well be a glimpse of the future.

On the topic of SVG and Canvas, I think it would be really useful if Canvas had a method similar to drawImage but instead could draw svg.

for example

var circle = document.createElementNS("http://www.w3.org/2000/svg, "circle"); circle.setAttribute("style", "fill:green"); circle.setAttribute("cx", 50); circle.setAttribute("cy", 50); circle.setAttribute("r", 25);

ctx.drawSvg(circle,x,y,w,h);

I think then we could have the best of both worlds, define complex shapes in svg, but use canvas for rendering. The advantage over just using svg is that every shape is in the dom, so if you want to draw 1000 similar shapes the dom gets cluttered.

This is only the case if the user has not got a cached version of jQuery, which is likely if something like google's hosting service. In this case the jQuery code may well be shorter than the css especially with all the browser specific rules. In addition the jQuery version will work in all browsers.

Would you care to elaborate on which app stores. I can see how people can make money developing mobile apps, but is it possible to get a decent revenue from say Chrome Webstore.

This is really amazing, just spent a few mins trying to pick out objects.

The Andromeda galaxy, the pleiades and the Orion nebula stand out in the photo in a very similar way to the real night sky.

This is really good, it would be good if there was a way to use these kind of things as screen savers. There are so many good browser visualizations!

What happens in Vegas stays in Vegas!

I bought an iPad2 the other day, the apple shop girl seemed pretty shocked that I had never owned an apple device before and even more so that I had never used iTunes. I might have showed her my £10 phone but that might have been too much for her.

As far as putting music on the iPad, I am not sure if I will even bother. There are plenty of cheap mp3 players which don't require converting wma files and itunes hastle.

The group your tabs feature in FF4 is very useful. The bookmarks manager is much more advanced than chrome.

Great article, particularly like the Top, Bottom or Somewhere in the Middle section. I had never considered how the position of e.preventDefault() would make a difference.

I thought microsoft had done enough to screw vista customers, with their slow and bloated OS. But theres more, now they can deprive them of IE10 when there seems to be no technical reasons.

I don't see the fuss, what does html5 really mean anyway, a bunch of stuff that was already in development was put under this umbrella term because it was easier to market.

Microsoft being a company that want to make profits have taken this one step further with running native html5 apps, it might not mean anything to a technical person but it is a good marketing pitch. They are successful because they are good at this kind of stuff and it is why some people still think the IE symbol is the internet.

Sorry to sound negative but I never understand why if someone goes to the bother of making something like this. Why they can't provide a checkbox to allow users on a desktop (without gyroscopes) to interact via mouse and see the effect.

Well it was nice while it lasted!

As a heavy user who rarely clicks the ads I could never understand how they could keep the service as it was. But on the bright side at least it is still free albeit with more restrictions.

Seville has one

but the idea is as old, Archimedes is said to have used mirrors to set fire to a roman fleet.

This reminds me of my old chemistry teacher, we used to enjoy watching his demonstrations because half the time they didn't work. Excuses would be made about a bit dirt must have been in the test tube or out of date chemicals etc.

But it made the lesson interesting (we wanted to see it fail), watching a well made video is less engaging than seeing a live demonstration.

This is all very well but if I unexpectedly get knocked down dead by a bus I will want my money back.
