The OS is being pitched as a better alternative for low-end smartphones in developing markets and is built around applications written using HTML5.
At Mobile World Congress, Mozilla has also joined forces with Ericsson and AT&T to show WebRTC, a framework that allows browsers to perform functions usually confined to mobile phones such as voice and video calls and messaging.
The WebRTC initiative is a project supported by Google, Mozilla and Opera

Announcing Xamarin 2.0 | Xamarin Blog
for printing (AirPrint) and media communication (AirPlay).
They are using Apple Bonjour protocol that works great at home,
but is "chatty" on larger, routed, network.
(based on multicast Domain Name System, mDNS service)
There are some third-party solutions for this issue:
They have a "IdeaBook" tool to keep links to useful home renovation projects...

iOS supports convenient "Share" button,
that is available in pre-installed apps, such as Safari,
but can also be added to other iPhone and iPad Apps.
This may even work from PhoneGap
Windows 8 / RT apps support similar concept of "Share Contracts" between apps,
available on slide-in menu from right side of the screen (circle with 3 dots that look like arrows).
The idea is that each app should do one thing (very, very well),
and use services from other apps for everything else:
i.e. sending email, or sending note to Facebook or Twitter, or file to DropBox etc.
As usual, the "devil is in the details", so while this is not too hard to implement
(once you figure it out), it depends on platform, other installed apps, security etc...
Many years ago Microsoft implemented COM for very similar purpose,
and that is quite complex, but works quite well, so much so that WinRT is also based on COM...
What is needed is "platform independent" extensive structured communication
that is not complex and brittle as SOAP XML web services,
but is more "structured" than plain JSON REST HTTP,
managed by local OS when on local machine,
and by online service "broker" for messaging between devices...
"Smart" share for "Smart" devices :)
"True to being futuristic, it's a two-seat, plug-in hybrid that can run 32 miles on electricity alone before its diesel engine kicks in. But even with that engine, it's hyper-efficient: VW boasts that it needs only 8.3 horsepower to cruise at 62 miles an hour.
Makes sense given that the engine has only two cylinders and puts out only 47 horsepower. The electric motor is good for another 27 horsepower.
"The 261-mpg fuel consumption figure is a record that has not been achieved by any other vehicle to date, showing that Volkswagen is redefining what is technically feasible in the automotive industry," the automaker says. XL1 also has a top speed of 99 mph and can accelerate from 0 to 62 mph in 12.7 seconds, according to VW."
It is unclear if VW will bring new super-efficient car to USA.
Maybe because the price of fuel may not be a big issue in coming years here :)

It is no surprise competition for such market is strong...
But it is hard to make a better product

Designed for home networks, Apple's Bonjour protocol
is a challenge for enterprise networks,
because it is "chatty", non-routable, and the only option on iOS.
Bottom line: coming after netbooks,
new windows devices need to be lower priced to sell.
What it does not mention is that netbooks became popular
because customers wanted them for portability and price.
Same as tablets now. Price does matter.
Chromebook is a new netbook, and Microsoft better come with some answer soon
if they want to maintain sales numbers, to be attractive for apps developers.
Simple: take same chromebook hardware, add $50 for Windows 8...
Why not just use Microsoft's OS?
Apparently using Linux+Android is still a better deal...
"Pixel Chromebook... aluminum case, 12.85-inch 2560 X 1700 resolution display that compares with Apple's Retina Display, and has a touchscreen.
What's inside? It's packed with an Intel i5 1.8GHz processor, 4GB of memory. 32GB of storage, Wi-Fi (a/b/g/n) dual-band, Bluetooth 3.0, a five-hour battery and it's 0.63-inches thick."
$1,299 (wi-fi), $1,449 (LTE)
So, retina pixels are expensive... almost as in MacBook Pro with Retina Display (13-inch, 2560 x 1600, $1,499.00)
I guess Google engineers have designed a device they would like to have :)
Something like Microsoft Surface Pro.

"Big data spans four dimensions:
But free e-book and report link comes with "Internal Server Error"
Oxford's robot car uses cameras and lasers instead of expensive 3D sensors and GPS
unlike Google's self-driving car, the British vehicle doesn't rely on an expensive LIDAR sensor. Instead, Oxford's RobotCar relies entirely on scene recognition (from cameras and lasers), matching live imagery with a preexisting database to figure out where it is, where to go
It could be only 15 years before self-driving systems become commonplace in cities as the price of installing the systems drops: "At present it costs about £5,000, but we're working to reduce that to £100," he said.

RunAs Radio: Sharepoint in the Military
the guest is a person who used to work in Military, and now in Microsoft,
in both places on SharePoint and effective ways to use it.
He mentioned shift that has happened after 9/11,
from "Need to Know" to "Responsibility to Share",
to make sure that right information is available for right people.
Besides being a good marketing for SharePoint,
this is makes sense for business, too.
Don't wait for "9/11" moment to learn to share info.
Richard's guest also mentioned common phrase
Data to Information to Knowledge to Wisdom
Latest SharePoint 2013 has improved metadata taxonomy/ontology features,
so it could help in making this "alchemy", if used properly.
And using it properly is a challenge...
Even finding info about this on Microsoft.com is a challenge...
mega-popular Q/A web site(s) for developers (and others),
for "family reasons"...
Well, apparently he didn't quite "retire";
he just got quiet until he and selected team
created a new "generic" discussion web site.
For ordinary people Q/A site is "a forum", and "discussions site" is "a forum".
But Jeff has proved to have much "higher resolution" for this kinds of things...
(at he loves ultra-high resolutions screens, too :)

smartwatch equipped with a camera and uses a clear flip-up cover that can display augmented reality information
I wrote about IPHONE in 1996 (!)
way before Cisco and than Apple made it famous :)
IPHONE was a title on page 166 in book "Internet"
by Dejan Ristanovic, Pavle Pekovic and Dragan Sretenovic (myself), and Dragan Vecerina (help with CD) and published in April 2006 by PC Press, Belgrade, Serbia.
In the "tools" section of the book I wrote about "Internet Phone" program VTIPHONE.
That was the time when the Internet was becoming a "big deal",
and I was deploying and promoting it in our local environment.
In 1995 I wrote a series of articles for PC Press magazine (in Serbian language),
and when Dejan suggested that we write a book about the topic
I enthusiastically embraced that... We even created a CD
with "snapshot" of popular web sites of that time,
an interesting "Time Machine" to view it now...
$80, 2 local RJ45 ports
Could we call it "Smart Router" and run apps on it :)

"BGI-Shenzhen, once known as the Beijing Genomics Institute, has burst from relative obscurity to become the world’s most prolific sequencer of human, plant, and animal DNA. In 2010, with the aid of a $1.58 billion line of credit from China Development Bank, BGI purchased 128 state-of-the-art DNA sequencing machines for about $500,000 apiece. It now owns 156 sequencers from several manufacturers and accounts for some 10 to 20 percent of all DNA data produced globally. So far, it claims to have completely sequenced some 50,000 human genomes—far more than any other group.
BGI quotes prices as low as $3,000 to sequence a person’s DNA. "
there is some "drama" in the process.
iMatrix, original creator of AMQP now has a different idea and solution: 0MQ
ØMQ for AMQP users
AMQP and ØMQ have quite different goals.
AMQP aims to commoditize existing enterprise messaging patterns,
while ØMQ aims to create messaging patterns that can succeed at Internet scale...
ØMQ is like Git (essentially distributed) whereas AMQP is like SVN (essentially centralized).
Advanced Message Queuing Protocol - Wikipedia, the free encyclopedia
is an open standard application layer protocol for message-oriented middleware. The defining features of AMQP are message orientation, queuing, routing (including point-to-point and publish-and-subscribe), reliability and security.
AMQP is managed by OASIS, same organization that standardized complex WS-* protocols,
by large enterprise vendors IBM, Oracle, Microsoft. Similar contexts, similar solutions...

A journalist has tried hard to show that Tesla Motors electric car
battery is not up to the task...
he just forgot that Tesla is a premier technology
and data-focused company, so no place for "cheating".
There are real data logs to show what actually happened
on the test drive. Tesla's passionate CEO is after all
also successively sending real rockets in space...
At its closest, Asteroid DA14 half the size of a football field flying at nearly 17,500 mph passed within 17,100 miles of Earth.
However, if, by chance, it did hit? The fallout would be devastating.
The asteroid would have crashed with the equivalent of 2.4 million tons of dynamite, creating a disaster of regional proportions similar to the 1908 asteroid explosion over Tunguska, Siberia, which flattened 750 square miles of forest.
The Russian meteor, likely about 49 feet wide and travelling at 40,000 miles-per-hour; Russia said 985 people sought medical care after the shock wave; 48 were hospitalized, mostly because of injuries caused by flying glass.
Meteors the size of the Russian one hit Earth every few years, Binzel says, but hit land near inhabited places much less often.
"These are two events separated by almost 24 hours, so it is unlikely they are connected"
Let's put the data into a perspective:
Earth's Diameter at the Equator: 7,926.28 miles (12,756.1 km).
So the asteroid was about 2 diameters of the Earth away.
The distance from Earth to Moon is 238,855 miles;
That is 30 times the distance of the Asteroid that flew by.
The distance of International Space Station to Earth is about 205 miles (330 km)
That is 38 times closer than the Asteroid.
Cruising altitude of airplanes is about 6 and 7 miles high.
The Asteroid was more than 1000 times far away than airplanes are...
So the Asteroid was relatively far away in human dimensions (vs. airplanes or ISS),
but relatively close in cosmic dimensions (compared to Moon).

This is video of his talk on dotJS conference in Paris, November 2012
dotJS. Symbiotic Languages:
A single person has created a truly great open source tool,
and after a few years it is getting a lot of attention and traction.
Microsoft has created a new tool as a part of ASP.NET,
that is solving similar challenge, in a similar way.
Great developers are on the task, and the tool is good.
But is it great? It is supported by Microsoft, but is it better?
It is also open source, but it has less contributors...
In any case, developers will win.
Complexity is out, and simplicity is in.
complex WCF / SOAP is out, simple(r) REST / HTTP is in.
(more) complex XML is (mostly) out, simple(r) JSON is in.
But SeviceStack is multi-talented: besides very fast JSON/HTTP,
it also supports other protocols and formats,
including Google's very efficient binary ProtocolBuffers, as well as SOAP,
then simple and fast ORM database access (vs. Microsoft EntityFramework)
then data caching, Redis access, view rendering by Razor, self hosting,
and can run on Microsoft .NET and Mono on Linux and Mac...
Here are links to podcast interviews, source code, web forums, training classes...
"14-inch display... 1.1GHz Intel Celeron 847 processor, a 16GB solid-state drive, an HDMI port, an RJ-45 Ethernet port, three USB 2.0 ports, 2GB of RAM (upgradable to 4GB), and an HD Webcam. It weighs 4 pounds and comes with a two-year deal for 100GB of storage at Google Drive."

"The idea behind a tiny and cheap computer for kids came in 2006, when Eben Upton and his colleagues at the University of Cambridge’s Computer Laboratory, including Rob Mullins, Jack Lang and Alan Mycroft, became concerned about the year-on-year decline in the numbers and skills levels of the A Level students applying to read Computer Science in each academic year. From a situation in the 1990s where most of the kids applying were coming to interview as experienced hobbyist programmers, the landscape in the 2000s was very different; a typical applicant might only have done a little web design.
Something had changed the way kids were interacting with computers. A number of problems were identified: the colonisation of the ICT curriculum with lessons on using Word and Excel, or writing webpages; the end of the dot-com boom; and the rise of the home PC and games console to replace the Amigas, BBC Micros, Spectrum ZX and Commodore 64 machines that people of an earlier generation learned to program on."
so it works on most of browsers, including IE6

Over time it slowly evolved to X3D
Latest 3D solutions are based on WebGL,
One such library is Google's O3D
Here is a sample game "Pool"
Quite impressive for a web app.
But let's put this in the perspective.
Moore's law improvement in performance in 16 years is about 2^8,
double every 2 years (or 18 months). That is 256 times.
Could Web 3.0 also be 3D?

A powerful hardware (Intel i5, 1920x1080, more memory etc),
but much higher price than Surface RT...
So the real competition are convertible tablets like Lenovo Yoga,
ultrabooks, or even MacBook Air.
All in all, a very nice, but still confusing device.
The actual issue is the price and weight: not a real iPad competitor.
So no large volume of sales, limited economy of scale...

“Free” two-day shipping. Streaming video. An e-book lending library. All for $79 per year.
Spelled out like that, Amazon Prime sounds like a weird ad hoc chimera of a product.
Why those three things? And why that price?
Though the value proposition may come across as clunky, plenty of people are apparently sold."
39 percent of the “product units” sold on Amazon during the most recent quarter
were from third-party sellers, up from 36 percent a year earlier.
sales on Amazon overall grew 32 percent during the quarter.
Third-party sales rose at an even faster clip — more than 40 percent
Amazon as a seller of stuff and to start thinking of the world’s biggest
online retailer as a platform for stuff — an API for the material world.
Amazon may be a unique company that by focusing on customers and long-term
time after time "surprises" market and succeeds by doing commons sense.
Amazon Web Services users report that for the same service,
prices are being reduced over time.
Now, Microsoft Azure is doing the same...

ABCs of SalesOld style: Always Be Closing.
New style: Attunement, Buoyancy, Clarity
- Attunement = I have to be able to take your perspective, not mine ("attune")
- Buoyancy = "stay aflot" in "an ocean of rejection". Sales people are always hearing “no”.
Buoyancy is how do you stay afloat in that ocean of rejection?
- Clarity = information is now abundant, so sales is more useful when it is not even clear what the problem / requirement is. Curating information, rather than accessing it. Help you surface this problem that you don’t even realize that you had.

Dr. Alan Kay, 1987: Doing with Images Makes Symbols Pt 1 : Free Download & Streaming : Internet Archive
Includes a video of "sketch pad" from 1962,
that is arguably better than most of current drawing apps.
"People aren’t using the app because they like the app or they like you.
They’re doing it because they like themselves. What are you doing to enable more of that."
So, the objective is to help your users/customers become really great in what they are doing.
They will share this with others, and that is the best advertising you can get (i.e. good reviews on Amazon :)
summary of presentation
- Models: examples of what good really is
- Edge Practice: helps point to the right thing
- Forward Flow: keep going, no matter what, even when things get difficult

"You've got to start with the customer experience
and work backwards to the technology.
You can't start with the technology
and try to figure out where you're going to sell it."
While there is a contradiction even in this brief video
(engineers did build a great laser printer that can sell)
a clear vision "customers first" helped make it better than HP's, by using PostScript and sharing,
sell it for twice the price, and create a new desktop publishing industry.
"Open Culture brings together high-quality cultural & educational media for the worldwide lifelong learning community. Web 2.0 has given us great amounts of intelligent audio and video. It’s all free. It’s all enriching. But it’s also scattered across the web, and not easy to find.

"3 months free" "BrowserStack" cross-browser testing at modern.ie
Microsoft marketing had a talent for mixing things together...
Promoting IE10 on one side,
and a new virtualization tools for testing on various web browsers,
(likely a side-effect of developing IE...)
An the virtualization can be "cloud" or "local"...
To get it, need to login to Facebook (why?).
Anyway, could be useful tools... just confusing...

"Git repos are now fully supported on Team Foundation Service and that Microsoft has released Visual Studio Tools for Git. You can now choose which source control system you prefer, either the centralized version control provided by Team Foundation Version Control (TFVC) or the distributed version control provided by Git"
The implementation is based on original libget2 library
so Microsoft is officially using, selling, and supporting code written by Linus Torvalds himself!
Next step: embedded Linux VM in Windows :)
And why not, Android VM for Windows and Windows Phone.
For now, Windows Azure can run Linux, as well as Java.
That is Open Microsoft 2.0
"Combined with an extremely efficient type of engine, called an ultra-high bypass ratio engine, the hybrid wing design could use half as much fuel as conventional aircraft. Although it may take 20 years for the technology to come to market, the manufacturing method developed at NASA could help improve conventional commercial aircraft within the next eight to 10 years"
