One need to be careful interpreting such data... for example if some value was already high,
even without "change" it may still be higher that some other region that started low and has big change.

Coursera has collected a huge number of classes from many elite universities, lead by Stanford. The format may not be always optimal for online teaching, but the quantity, and brand names, are there.
Udacity has nice custom classes, but it will require a breakthrough
("revolution") to make such custom method compete with "classic"
("evolution") recordings from existing universities.
edX is similar to Coursera, just a smaller "club" of MIT, Harvard, Berlekey, etc.
Common for Udacity and edX is that they are using YouTube for storing videos. Coursers appears to have a custom storage.
In any case, this are all fascinating resources for learning.
So, to purchase all apps from the store it would cost $1.1 M

Most of VMs of "managed" programming languages/platforms, such as Java, .NET, Ruby, Python etc. are written in C or C++.
a subset of language is used ("js.asm").
When this could be useful?
Re-using existing code, maybe.

Agile Alliance :: KEYNOTE: The Power of an Agile Mindset
... much of Agile's success was the result of the placebo effect, that is, good things happened because we believed they would. The placebo effect is a startling reminder of the power our minds have over our perceived reality. Now cognitive scientists tell us that this is only a small part of what our minds can do. Research has identified what I like to call "an agile mindset," an attitude that equates failure and problems with opportunities for learning, a belief that we can all improve over time, that our abilities are not fixed but evolve with effort.

"What is Native Client?
NaCl is a special-purpose environment for running adapted C or C++ programs in a browser at close to the native speed. It provides security mechanisms to ensure that people aren't just clicking on a link and running malware that could wreak havoc on their machines. It can handle software that's heavily threaded -- meaning different elements run simultaneously for better performance.
By running programs adapted from their original form written in the C or C++ programming languages, Native Client reaches close to the speed of native software on a PC. Google thinks NaCl speeds can approach a few percent of native-software speed."
In raw computation speed asm.js could match Native Client" for a project like the Google+ photo-editing software, Eich said,"

When Mercedes-Benz axed its Maybach brand last year after an unsuccessful revival of the nameplate
... Mercedes would have you call the sixth-generation S-class “the best car in the world,”
And the car really has impressive features...
It is just that Elon Musk is sure that Tesla Model S
will be worth more 3 years after purchase than Mercedes Class S.
And reviews so far say that Tesla Model S is the "best car"...
(At least it was until new Class-S is reviewed...)
And since Tesla is all electric, there no smell of exhausts,
so it does not need a fragrances, like Mercedes's gasoline cars :)
And it has bigger 17" touchscreen...

"Carl and Richard talk to Matthew Podwysocki about the latest news around Reactive Extensions. Matthew starts out talking about how Reactive Extensions has moved into open source in a big way, with lots of cross platform support
The reactive manifesto
- react to events: the event-driven nature enables the following qualities
- react to load: focus on scalability rather than single-user performance
- react to failure: build resilient systems with the ability to recover at all levels
- react to users: combine the above traits for an interactive user experience

"Arduino, Gadgeteer, Netduino, Android ADK, Seeedstudio Grove, and Raspberry Pi. "
It is likely that Microsoft's "Devices & Services Company" strategy is "inspired" by Apple and Google.
High-end devices are fairly profitable (for Apple at least),
and with Google undermining price of software (can't beat free),
online services are a relatively safe bet...
For enthusiasts there are now many choices for DIY gadgets...
That may not be Microsoft's business strategy,
but sure is interesting...
A nice explanation how human brain works with hierarchy of abstract concepts and pattern recognition,

With enough computing power, that could be emulated with AI.

"Nokia Lumia Android device was not only a possibility, it was real. "
The contract with Microsoft was expiring in 2014, so if Microsoft didn't act as it did,
they could have lost a major manufacturer of Windows Phones...
So they almost didn't have a choice... Maybe that was Nokia plan anyway,
to force Microsoft to buy them...
And here is one crazy idea: how about running Android apps on a Windows Phone?
That should be possible with a little bit of tweaking...
Instant access to many apps, and a reason for developers to develop for both...

"Apple will sell its 700 millionth iOS device next month.
“iOS 7 will quickly become the world’s most popular operating system,”"
How about Android, and Windows?
Clever Statistics :)
iOS is auto-updated to latest version,
and both Android and Windows keep many old versions...
Windows 8.1 may try to fix that, by providing a free upgrade.
A strange thing is that most of iOS mobile devices cost more than average Windows desktop or laptops...
A good business... while it lasts...

"on Chrome's fifth birthday, (2013-09-05) Google is announcing the rollout of what it's calling Chrome Apps... Chrome has been serving up web apps since 2010 when the Chrome Web Store opened up alongside the launch of the Chrome OS. Chrome Apps, however, are different than what's been offered before...
The new apps look and behave much like the native apps you find on Windows and OS X. They're built using web technologies, but also with Chrome-specific code that means they won't be able to run on other web browsers...
They can exist outside of your browser window as distinct apps, work offline, and sync across devices and operating systems. They can also access your computer's GPU, storage, camera, ports, and Bluetooth connection. "
Essentially, this is an equivalent of PhoneGap now bundled with Chorome browser, so web-based apps can access other resources of computer (to work offline), and to avoid tabs, address bar and other "chrome" of the browser... Clever, but how secure it is?

Reactive programming (RP) is based on data flows and the propagation of change, with the underlying execution model of a programming language automatically propagating changes through the data flow. With the popularity of event-driven, scalable, and interactive architectures both on the server and the client, the concept of “reactiveness” is increasingly gaining attention.
Principles of Reactive Programming | Coursera

hedge fund wants Microsoft to become more of an enterprise software and business services company as opposed to one focused on the retail consumer."
Also as part of the deal, Nokia’s CEO Stephen Elop will be stepping aside as Nokia President and CEO to fill a new role at Microsoft as “Nokia Executive Vice President of Devices & Services.” Being that Elop has emerged as a leading rumored contender for the soon-to-be-vacant spot at the helm of Microsoft, this could be a strong signal about the future of Microsoft’s executive leadership.
@zdnet Under the terms of the deal, Microsoft will acquire around 32,000 people Nokia employees, including 4,700 people in Finland and 18,300 employees directly involved in the manufacture, assembly, and production of devices worldwide. Nokia will also assign its long-term patent licensing agreement with Qualcomm, a smartphone chip maker, and licensing agreements, to Microsoft as part of the deal.
Next in line: Blackberry...

Bringing pages alive with CSS Transforms & Animations:
"CSS Transforms are a powerful feature that allows you to manipulate elements of your Web Content in much more interesting and flexible ways than traditionally possible through CSS markup. The specification provides support for rotations, translations, scaling and skewing (as well as arbitrary transforms and compositions of multiple transforms). Combined with the ability to manipulate elements in 3D space, alter the center of projection and affect the origin of transformations, CSS Transforms can be somewhat daunting at first sight for the uninitiated.

#34. A Summary of ‘The Infinite Resource: The Power of Ideas on a Finite Planet’ by Ramez Naam | New Books in Brief
And the really wonderful thing about our ability to innovate is that, unlike natural resources, it does not shrink over time. Rather, it only expands. This is because innovation is built on ideas, and ideas themselves only grow and multiply. Ideas can even be shared without ever being diluted. Instead, the sharing of ideas often generates even more ideas. The power of ideas—and the innovation that goes along with it—truly is an infinite resource.
about author: Ramez Naam (scientist, ex Microsoft executive)
One observation from the book is that patents have enabled easier
sharing of ideas. Patents laws started in 1474 in Venice,
and this coincided with greatest expansion of technology, science and wealth creation...
Trouble is that the system of patents now really protects only biggest companies (Microsoft, Apple and similar).
From this book such semi-monopolistic system was main reason for China not to progress as fast as Europe, where a dynamic market of small players enabled fast evolution of ideas...
Time to improve market of ideas?
