Associating numbers with specific characters has proved necessary to allow automated telegraph printers (teleprinters) and then computers to represent text. The most widely used mapping between numbers and letters was that approved on June 17, 1963, by the American Standards Association. It is the American Standard Code for Information Interchange, better known as ASCII. Make a wish and blow out the candles: iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii

Once at a picnic, I saw mathematicians crowding around the last game I would have expected: Tic-tac-toe. As you may have discovered yourself, tic-tac-toe is terminally dull. There’s no room for creativity or insight.... But the mathematicians at the picnic played a more sophisticated version... The extra dimensions add a little challenge to a dusty old game.

Today, pretty much everyone has a CPU, a DSP and a GPU, buried somewhere in their PC, phone, car, etc. Most don't know or care that they bought any of these, but they did. Will everyone, at some future point, also buy an FPGA? The market size of FPGAs today is about 1% of the annual global semiconductor sales (~$3B vs ~$300B). Will FPGA eventually become a must-have, or will its volume remain relatively low? Programmability is a feature, not just a tax on efficiency.

While your quote there is a good one the article is not that well. I had trouble getting past his gaping error in power consumption:
Quote: …we estimated that high-end FPGAs implementing demanding DSP applications … consume on the order of 10 watts, while high-end DSPs consume roughly 2-3 watts. Our benchmark results have shown that high-end FPGAs can support roughly 10 to 100 times more channels on this benchmark than high-end DSPs…
So for that benchmark, FPGAs offer 10x-100x the runtime performance, and 2x-30x the energy efficiency of DSPs - quite impressive!
Ahhh... the FPGA is actually 3x worse on power is what that says.
Anyway, I continued. He then went into to say how it "cheats" but not really by including DSP slices and refers back to how much faster it is now etc.
What it seems the writers is failing to realize is FPGAs MUST be better than high end DSPs and many other chips sets because of the purpose (which he claimed in the beginning is not their purpose). Putting a fixed chip set on them to enhance them makes sense. Especially to further enhance/design new DSP chips.
Programmability is a feature. However FPGAs will never make it to the consumer. It simply does not make sense. Thats not to say that some other technology won't come along and provide us reprogramable CPUs and such. But FPGAs as they stand are intended to design such circutry.
WITH THAT SAID, there are cases where there are FPGAs on board various devices and users are already using them and unaware. However this is not because they are intended to be reprogrammed. It is purely separation of design and development. On company will make a board with various chips and hand of to another and give them better hardware control with an on-board FPGA. That company will then program the FPGA and resell the board in some other device. That company could also strap another FPGA on for other companies to integrate with.
Once design is done however anywhere in the chain it is likely cheaper to remove the FPGA and have the company sell you their component with a provided chip set.
Truth is though technology moves so fast we never get to that phase. We end up with the tech being obsoleted before the SOC (system on chip) can be made and provided. HOWEVER, we also obsolete it before the FPGA is ever "reporgrammed". The only purpose of it was for design parallelism.
Computers have been intelligent for a long time now. It just so happens that the program writers are about as effective as a room full of monkeys trying to crank out a copy of Hamlet.

By day, David Auld is an Offshore Installation Manager (OIM) in the oil and gas industry. But when the production platform is humming along without him, Auld indulges his hobby as a devout “petrol-head” (car enthusiast). He also finds time to feed a passion for programming, which led to him earning a 2012 BSC Honours Degree in Computing. Surprisingly, these three facets of the native Scotsman all converged when Auld won the Entertainment Category of the Intel App Innovation Contest. From Top Gear to Top Winner: Our own Dave Auld wins!

Thomas Ptacek tweeted yesterday that "If you're not learning crypto by coding attacks, you might not actually be learning crypto." Judging by the number of twitter "favourites" and "retweets" of this comment, it seems to have struck a chord; but with all respect to Thomas, I absolutely disagree. Not only is it possible to learn cryptography without writing a line of code, but coding attacks is entirely useless for learning about modern cryptography; the best route to learning modern cryptography is a study of mathematical proofs. Attacking modern security is mostly looking for bugs in code, not the underlying cryptography.

Is it just me or does the entire news media — as well as all the agitators and self-righteous bloviators on both sides of the aisle — not understand even the rudiments of electronic intercepts and the manner in which law enforcement actually uses such intercepts? It would seem so.

I'm interested in people's current predictions on what will happen to the various languages over the next few years. Java has had a bad press in recent years but has a major new release. Is this a new lease of life, particularly with Android taking off so rapidly? What languages and frameworks are on your radar today... and tomorrow?

Still learning Python - a nice but boring language. I like Perl better, crazy as it sounds.
Also C++ 11.

Many years ago, back in Uni, I saw 2 guys in a computer lab writing a whole programming assignment without running it even once. The program was of relatively decent size written in C and consequently there were hundreds of compilation errors. That’s so silly, I thought.... After graduation I used to be a C++ programmer. The syntax sometimes was quite tricky and you would often compile after every new line of code. Sometimes, you would dare to write a whole function, just to find 10 compilation errors. Since then the way I code has changed with help of modern IDE... Do IDEs help you code better, or just keep up with ever more complicated systems?

Interesting the C# questions are not as common. Java seemed to be on the ropes at one time, but has had a resurgence. The weakness of C# may be an indication of the bad strategic moves the Microsoft has recently made in basically eliminating support of Silverlight, and making an OS (Windows 8) that does not provide precieved enhancement for desktop users. Is Android the future. Maybe. Meanwhile I am a C# programmer working with WPF.

A girl I worked with would start editing in the morning and only compile her code late in the afternoon. Astonishingly, her compile failure rate was really very low which is a testament I suppose to her ability to master the methods and syntax, all without Intellisense. Quite incredible how she could do that.
If there is one thing more dangerous than getting between a bear and her cubs it's getting between my wife and her chocolate.

At the age of 13 I wrote ~500 lines of Sinclair BASIC over 5 to 6 hours one Saturday without running it to check it. When I did run it there were 2 syntax errors, just typos which I fixed then and there.
The code then ran without error and did exactly what I expected.
I knew that was a very special day and nothing like that would probably ever happen again.
It was 20 years before with the help of an IDE I could hope to write 500 lines of boilerplate C++ in a day with as few mistakes. I'm not sure if I've ever done it but I've probably got close on a few occasions.

Ever wondered how the pro’s physically manage to make a module? Well ok, you can get a fancy pick and place machine or send off for someone to assemble your module, but you can do it by hand. It is not as hard as expected. As part of a .NET Gadgeteer hands on event at the Modern Jago in Shoreditch we were delighted to have Justin Wilson from Ingenuity Micro attend and show us how things are done (www.ingenuitymicro.com). He has designed and built an nice collection of .NET Gadgeteer modules and mainboards and expects to have them available shortly. Old-school .NET hacking... with solder.

Code review is a tricky business. Code is full of hidden mines that lay dormant while you test just to explode in a debris of stack trace at the most inopportune time – when its in the hands of your users. The many times I’ve run into such mines just reinforce how important it is to write code that is intention revealing and to make sure assumptions are documented via asserts. Such devious code is often the most innocuous looking code. We are miners, code bug miners. To the code base we must go...
