"Google has released a research paper that suggests C++ is the best-performing programming language in the market. The internet giant implemented a compact algorithm in four languages - C++, Java, Scala and its own programming language Go - and then benchmarked results to find 'factors of difference'."

faster than programs coded in, say, assembly? I kind of find that hard to believe.
Very few people can write code as good as a modern C++ compiler.
I work with a guy who kept bragging about how great his LU factorization that he hand-coded directly in assembler is. Well, turns out this clown wrote it using the ancient x87 FP stack, he never heard of SSE (this was a few months ago).
So, I through together a quick and dirty LU factorization in C++ (OK, copied it out of numerical recipes), compiled it with gcc 4.4, enable SSE, and it was about 20 freaking times faster than his "hand tuned assembler"
And when the next great SSE 4,5,6... comes out, all I do is re-compile:)
Unless they have a really really good reason for doing it, when someone tells you they want to write something in assembler, you should probably back hand them.

Agree completely with you.
Assembler has THE POTENTIAL that could help writing the fastest algorithms; but just real geniuses get full advantage of such potential.
If you have 1000 man; all of them will be able to cut a wood into pieces; 20% of them will be able to build a chair with the wood but just one or two will be able to create a beautiful, durable, reliable chair

I've done some work in Assembly and I tend to agree with you. It is possible to make Assembly code that's smaller and more efficient than C/C++, but it is rarely worth it. And most people aren't going to write asm that's better than a modern compiler with optimizations turned on.
But it is nice to have the option of falling back on Assembly code when you really need to cut corners.

The day has finally come! Jolla has finally announced the launch device for its Sailfish operating system - and by god this is a looker. It's decidedly different from other phones out there, but it has good specifications and carries a relatively reasonably price tag - EUR 399, and it's up for pre-order today, shipping in the fourth quarter of this year.

Why does Google get so much credit in the technology industry? Why, despite the company's many obvious failings, do many geeks and enthusiasts still hold a somewhat positive view on the all-knowing technology giant? A specific talk at Google I/O this week provides the answer.

"Windows is indeed slower than other operating systems in many scenarios, and the gap is worsening." That's one way to start an insider explanation of why Windows' performance isn't up to snuff. Written by someone who actually contributes code to the Windows NT kernel, the comment on Hacker News, later deleted but reposted with permission on Marc Bevand's blog, paints a very dreary picture of the state of Windows development. The root issue? Think of how Linux is developed, and you'll know the answer.

This is one of those news items that's fun to write, fun to read, fun to comment on, and where no one will be able to say anything unkind. It's all just one big ball of awesome fluffiness. TuneTracker, the BeOS radio automation software, has just released something very special: TuneTracker System 5, the first version designed entirely and specifically for Haiku. In fact, it actually includes Haiku in the software package. Better yet, TuneTracker also unveiled several system-in-a-box products - which have Haiku and TuneTracker pre-installed.

Exactly twenty years ago, a document was published that played a huge role in establishing the web as we know it today. Twenty years later, and this simple and straightforward document is proof of an irrefutable fact: while closed technologies can change markets, open technologies can change the world.

Oh multitasking. That staple of computing that got thrown out the window with many modern smartphones. We got some rudimentary thing in its place - but even as multitasking on phone and tablets improves, its user-visible side remains cumbersome. Windows 8 has a neat implementation, and now it's time Android follows in it footsteps.

They're here! Whether that excites you or not remains to be seen, but the Galaxy S4, which will most likely become the best selling Android smartphone of the year by a huge margin, has been reviewed by all the major sites, and there's lots of interesting conclusions in there - although I think most of you will get the gist.

Nokia has posted its quarterly results for the first quarter of 2013, and just like the quarters that came before, there's not a whole lot of good news in there. The rise in Lumia sales still can't even dream of making up for the sales drop in Symbian phones, and when broken down in versions, the sales figures for Windows Phone 8 Lumias in particular are very disappointing. In North America, Nokia is getting slaughtered.

The day has finally come: Google has started shipping Google Glass to the lucky few early adopters. Now that it's shipping, Google has also unveiled a lot more about the API and the specifications of the device itself. While the company had already given out substantial details at earlier occasions, there are still a few surprises here.More Features »
