Khan Academy Launches The
Future of Computer Science Education http://techcrunch.com/2012/08/14/khan-academy-launches-the-future-of-computer-science-education/ “…Computer Science is an intensely creative
field,” says Shantanu Sinha, President of Khan Academy, which gave TechCrunch
an exclusive look at their brand new education portal that teaches Computer
Science fundamentals through interactive drawing. “We really wanted to focus on
creating something that could inspire young children, and get them excited and
motivated to explore CS further.” The portal’s interactive design is a major
evolutionary step for a website that has since been almost entirely based on
YouTube lectures (with over 178 million views). I rarely get excited about
online education, which often just recycles our antiquated education system
into a digital format, but the new Khan Academy Computer Science project is beyond
impressive. The new Computer Science site focuses on the critical early
adolescent years, where children broaden (or narrow) their interests and
identity before high school. The lessons don’t get much more complicated than
basic algebra, and how these intuitive mathematical concepts can create
powerful artistic, video game, and website experiences. “We wanted to create
something that could get anyone with minimal knowledge of Computer Science
really excited by the field–no matter what their age or situation,”…The heart
of the design places a simplified, interactive text editor that sits adjacent
to the code’s drawing output, which updates in real time as students explore
how different variables and numbers change the size, shapes, and colors of
their new creation. An optional video guides students through the lesson,
step-by-step, and, most importantly, can be paused at any point so that they
can tinker with the drawing as curiosity and confusion arise during the
process…”

SkyDrive gets a Windows 8
look-and-feel, Android app coming soon http://arstechnica.com/information-technology/2012/08/skydrive-gets-a-windows-8-look-and-feel-android-app-coming-soon/ “After giving its free e-mail service a new
Windows 8-inspired coat of paint with Outlook.com—which has seen more than 10
million users sign up already—Microsoft has turned its attention to cloud
storage service SkyDrive. Over the next 24 hours, the company is rolling out a
new "modern" interface for SkyDrive's online component. While
Outlook.com didn't add many new features—behind the scenes, it's pretty much
identical to Hotmail—SkyDrive has picked up a bunch of new capabilities in
addition to its new appearance. In the Web front-end itself, SkyDrive is now
searchable, including the ability to search for text within Office documents.
File handling has been streamlined, giving users the ability to select multiple
files and drag and drop them to move them between folders. Sorting is also
smarter; there are new ordering options and a facility to save sort options on
a per-folder basis. SkyDrive's apps are being enhanced as well. Over the next
week, Microsoft is rolling out an update to the Windows and Mac OS X SkyDrive
clients. The new version will be faster at uploading files to the cloud and
will use less processor time when checking your system for changed files…”

Long-lost Egyptian
pyramids found on Google Earth? http://www.pcworld.com/article/260857/google_earth_shows_undiscovered_pyramids_amateur_archeologist_claims.html “Google Earth is prompting one arm chair
archeologist to suggest that there may be two undiscovered pyramid complexes in
Egypt. Both locations feature what appear to be pyramid-shaped mounds with a
deliberate organizational structure, according to Angela Micol of Maiden, N.C.,
who runs Google Earth Anomalies. As its name suggests, the site is dedicated to
discovering intriguing images from Google Earth…Micol says she is not
publishing the coordinates of the two sites for fear they may be pillaged by
treasure hunters. Nevertheless, by piecing together the general locations of
these sites from other reports, it took me less than 15 minutes to find both
locations using Google Earth and Google Maps. I expect anyone else armed with a
Web browser and a modicum of Google savvy would have a similar experience. The
first site is located just a few miles from the ancient ruins of Dimeh in
Middle Egypt, not far from the city of Faiyum. The site features what appears
to be one large mound and three smaller ones. Micol believes the three smaller
sites echo the diagonal arrangement of the famed pyramids of Giza…”

Swiss scientists develop
algorithm to sniff out source of malware, spam attacks http://www.computerworld.com/s/article/9230199/Swiss_scientists_develop_algorithm_to_sniff_out_source_of_malware_spam_attacks “Swiss scientists have developed an algorithm
that can be used to locate spammers as well as the source of a computer virus
or malware. The algorithm finds the source by only checking a small percentage
of the connections in a network…If you would like to find the source of a
virus, malware or spam-attack it is impossible to track the status of all nodes
on the Internet, Pinto said in a telephone interview. "That would mean you
would need about 1 billion sensors. And you don't want to monitor the entire
Internet…Instead he and his colleagues devised an algorithm that shows that it
is possible to estimate the location of the source from measurements collected
by sparsely placed observers or sensors. By using the algorithm the specific
computer inA the network from which the spam mail is being sent can be found so
that the network provider can shut it down for instance, said Pinto. Using the
same method, the first computer where a virus was injected could be
pinpointed…”

Stratfor emails reveal
secret, widespread TrapWire surveillance system http://rt.com/usa/news/stratfor-trapwire-abraxas-wikileaks-313/ “Former senior intelligence officials have
created a detailed surveillance system more accurate than modern facial
recognition technology — and have installed it across the US under the radar of
most Americans…Every few seconds, data picked up at surveillance points in
major cities and landmarks across the United States are recorded digitally on
the spot, then encrypted and instantaneously delivered to a fortified central
database center at an undisclosed location to be aggregated with other
intelligence. It’s part of a program called TrapWire and it's the brainchild of
the Abraxas, a Northern Virginia company staffed with elite from America’s
intelligence community. The employee roster at Arbaxas reads like a who’s who
of agents once with the Pentagon, CIA and other government entities according
to their public LinkedIn profiles…The details on Abraxas and, to an even
greater extent TrapWire, are scarce, however, and not without reason. For a
program touted as a tool to thwart terrorism and monitor activity meant to be
under wraps, its understandable that Abraxas would want the program’s public
presence to be relatively limited. But thanks to last year’s hack of the
Strategic Forecasting intelligence agency, or Stratfor, all of that is quickly
changing…Mr. Ferguson and others have mirrored what are believed to be most
recently-released Global Intelligence Files on external sites, but the original
documents uploaded to WikiLeaks have been at times unavailable this week due to
the continuing DDoS attacks. Late Thursday and early Friday this week, the GIF
mirrors continues to go offline due to what is presumably more DDoS assaults.
Australian activist Asher Wolf wrote on Twitter that the DDoS attacks flooding
the servers of WikiLeaks supporter sites were reported to be dropping upwards
of 40 gigabits of traffic per second. On Friday, WikiLeaks tweeted that their
own site was sustaining attacks of 10 Gb/second, adding, "Whoever is
running it controls thousands of machines or is able to simulate them…” http://venturebeat.com/2012/08/10/wikileaks-trapwire-stratfor-cia/ “…TrapWire does three things: protect
critical infrastructure by analyzing CCTV footage with face and pattern
recognition algorithms to detect pre-attack patterns, provide online reporting
systems for citizens to report suspicious behavior, and gather and analyze many
sources of information to allow law enforcement to make sense of the masses of
collected data…”

Lenovo ThinkPad Tablet 2 http://reviews.cnet.com/tablets/lenovo-thinkpad-tablet-2/4505-3126_7-35411720.html “As Windows 8 nears its debut on October 26,
you can expect to see a ton of Windows computing devices, tablets and
otherwise, set to take advantage of the touch-friendly features of Microsoft’s
next operating system…One of the first announced tablets is the Lenovo ThinkPad
Tablet 2…ThinkPad Tablet 2 runs a full Windows 8 Professional OS, but does so
on a next-gen Intel Atom processor…Setting the ThinkPad Tablet 2 apart from
other tablets on the market will be its optional digitizer and pen for
precision input, a stylus that slides out of the side of the tablet and works
the way most Windows tablet styli have in the past. The antiglare 10.1-inch IPS
display has a 16:9 1,366x768-pixel resolution matching that on most Windows
laptops…The ThinkPad Tablet 2 is 9.8mm thick and weighs 1.3 pounds, and feels
about the same in terms of heft as a third-gen iPad…The tablet's equipped with
a mini-HDMI connector, headphone/microphone jack, MicroSD card slot, a USB 2.0
port, and a docking connector for keyboards..How will an Atom processor handle
a full Windows 8 computer? That remains to be seen. The tablet’s responsiveness
was…far better than previous Windows 7 tablet experiences…”

positive reaction that Google's $200 Nexus 7 has garnered, Barnes & Noble
has just cut down the prices on all three of its Android-based, seven-inch Nook
Tablets. The 16 and 8GB models have been respectively reduced to $199 (from
$249) and $179 (from $199), while the Nook Color is priced 20 bones cheaper
than before at $149…”

10 tethering apps for
Android http://www.eweek.com/c/a/Mobile-and-Wireless/10-Tethering-Apps-for-Google-Android-Smartphones-301876/ “With a growing number of smartphones or
tablets allowing tethering, a July 31 decision by the Federal Communications
Commission that Verizon Wireless must pay the U.S. Treasury $1.25 million for
preventing customers from downloading Android tethering apps was a victory for
fans of the technology. Tethering refers to sharing the Internet connection of
a handset with other devices such as notebooks or desktops; with tethering
applications, connecting a smartphone with other devices can be done over
wireless LAN (WiFi), through Bluetooth or by physical connection using a cable
through USB. Google’s online Android marketplace, Play, currently offers a wide
selection of tethering applications, many of them available free—although some
can cost users up to $15 for the service—and Android’s robust community of
users offer useful, if opinionated, information on the best ones. Here’s a look
at 10 different Android tethering apps to get you on the Web and create mobile
hotspots for all your different devices…”

Review: Android's
"Google Now" can teach Siri a few tricks http://arstechnica.com/gadgets/2012/08/review-androids-google-now-can-teach-siri-a-few-tricks/ “Android 4.1 "Jelly Bean" launched…this
June with an unexpected flavor: an impressive new virtual assistant called
Google Now. The Google Now feature set is tough to summarize. It builds on the
voice actions system that Google offered in previous versions of Android,
adding support for natural language queries, but it also has a passive mode in
which it will display contextually relevant information through Android’s notification
system…The voice control interface in Google Now operates much like Apple’s
Siri; the software records and interprets the user’s voice, parsing full
sentences of natural speech into commands. It responds by speaking back to the
user and displaying relevant information. You can use the speech interface to
dictate an e-mail or text message, search Google, perform a calculation or unit
conversion, get the definition of a word, get a stock quote, search the
platform’s built-in addressbook, set an alarm, play a song, get travel
directions, get the current weather conditions in a region, or launch an
application. The range of supported commands and queries is comparable to
Siri's. The passive information mode uses a wide array of data—including the
user’s location, schedule, and search queries—in order to provide useful
information on a preemptive basis. When the user has a meeting, for example,
Google Now will helpfully offer directions to the location and an estimation of
how long it will take to arrive there in current traffic conditions…We tested
Google Now in Android 4.1 on a Nexus 7 tablet and on a Galaxy Nexus smartphone.
We tested a wide range of queries and searches, then spent some time comparing
Google Now to Siri to see how it stacks up against Apple’s implementation…”

Vlingo Labs: Better Voice
Actions for Android http://thedroidguy.com/2012/08/vlingo-labs-better-voice-actions-for-android/ “Most of the smartphone companies are
venturing into voice recognition technology. It all started with Apple’s Siri
on iPhone 4S [not true; Android had voice
actions before Siri was released – ed.]…Companies like Blackberry and
Microsoft are creating their own voice recognition softwares for their
operating systems so that they can compete with Apple’s iOS, but in the
meantime several apps have filled the Android landscape to bring such
functionality to the open source operating system…In the recently launched
Samsung Galaxy S III, the South Korean mobile giant has come up with something
called S-Voice, a competitor for Apple’s Siri. S-Voice is officially available
only on Samsung’s flagship phone for 2012, and is essentially based on Vlingo…Vlingo
have been very busy with experimenting ways to make Vlingo more functional
& innovative, and Vlingo Labs (Beta) users can check out the hottest new
features that can perhaps end up in the official final Vlingo Virtual Assistant
app. Currently, the Vlingo Labs is restricted to Ice Cream Sandwich device
users and it is strictly a “test kitchen” where shiny new ideas and test
features are brought to life and may not end up in the final app itself…”

Google Translate can now
translate text in images through your phone's camera http://www.zdnet.com/google-translate-can-now-translate-text-in-images-through-your-phones-camera-7000002450/
“Google has pushed out a new version of
its Translate app for Android, adding optical character recognition to the
linguistic toolkit. The feature means users can, for example, use their Android
phone's camera to take a picture of a menu in a foreign language, then have the
app translate the text into their own tongue…Still in alpha after 18 months,
the most ambitious tool in that set is probably speech-to-speech translation,
which theoretically allows two people to speak to each other in different
languages with the app acting as a translator…”

Google Merges Gmail With
Web Search http://www.wired.com/business/2012/08/google-adds-siri-like-qa-to-app-merges-gmail-with-web-search/ “Google is taking a major swipe at Siri with
a new feature in its iPhone and iPad search apps that mimics the
question-and-answer abilities of Apple’s digital concierge. The more
conversational version of Google’s voice search debuted today at a press event
in San Francisco. Top members of the company’s search team also announced a new
version of the company’s web search that integrates Gmail to personalize the
results of everyday searches. The technology tying these new options together
is what Google calls its Knowledge Graph, its fledgling effort to extend
search’s understanding of the world beyond keywords. Google engineers say the
company’s search engine now “knows” a half-billion real-world objects and 3.5
billion connections among those objects. In practice, this means when you ask,
“When’s my flight?” or say, “Show me a video that explains quantum physics,”
Google’s algorithms understand what you’re talking about—and, more importantly,
what you’re trying to find out…Android users running the latest Jellybean
operating system have already had this Siri-like voice-based
asking-and-answering capability for the last few weeks, said Scott Huffman,
Google’s director of mobile engineering. The updated iOS version of the Google
Search app was submitted to the Apple App Store last week and should be
available within the next few days, Singhal said. Huffman showed off the app’s
fluency by peppering it with questions from “What will the weather be like this
weekend?” (foggy and 68 degrees) to “What is (struggling San Francisco Giants
pitcher) Tim Lincecum’s salary?” ($18 million). The app answered quickly and
clearly, though in a voice that sounded slightly more robotic and stilted than
Siri’s…”

Google+ Hangouts Studio
Mode Lets Musicians Stream Concerts With Pristine Sound Quality http://techcrunch.com/2012/08/13/google-hangouts-studio-mode/ “Google wants Hangouts On Air to become the
way musicians stream concerts from their garage or the stadium, so today it
launches Studio Mode, an option that lets broadcasters optimize sound quality
for real-time music instead of voice. Studio Mode makes a big difference,
turning the noisy digital gargle into something closer to CD-quality. I’ve
confirmed with Google that Studio Mode streams in stereo at a higher bitrate
through a different codec…Ustream is a popular choice for artists to share
their concerts with people at home, but Google could get everyone rocking
Hangouts if Studio Mode makes listeners feel as if they’ve traded their crappy
old MP3 for vinyl…Without Studio Mode, Hangouts sound like they’re playing
through crappy Apple earbuds…Voices crack, drums seem distant, and rich bass
and guitar tones sound sound flat and empty. Once enabled, its like you’ve been
transported into the room with band. The bass rumbles, vocals retain emotion,
and the high frequencies feel sharp and clean. Studio Mode is available as an
audio setting in Hangouts On Air, an extension Google’s video chat service that
let people stream to an unlimited audience instead of just 10 people…”

Wake up and smell the
Chrome http://blogs.computerworld.com/windows/20819/wake-and-smell-chrome “…I've been using a Google/Samsung Chromebook
and Langa's article crystallized the difference between computing with Windows
and Chrome OS…The phrase "night and day", doesn't do it justice…to
someone willing to think out of the box, to see the forest rather than just
trees, its an eye-opener to how crude and rickety Windows is. I was..interested
in…how he maintains his Windows computer. He detailed his routine…If the
tune-up software being tested found problems (and they all found hundreds, but
that's another story) it said more about the software than the computer. This is Langa's ongoing care and feeding
routine for his Windows machine: Constantly
running antivirus software…Constantly running Malwarebytes Anti-Malware (to
catch what the antivirus software misses)…From "time to time" he runs
still more antivirus software (ESET’s Online Scanner, Microsoft’s Safety Scanner
and Trend Micro’s House Call)…Windows Update keeps the OS patched…Secunia PSI
keeps the "most important software up to date and free of known security issues"…To
remove bogus Registry entries, junk files and cookies he uses Piriform’s
CCleaner and/or Macecraft’s free PowerTools’ Lite every day…For "a deeper,
more controlled cleaning" he uses Macecraft’s jv16 PowerTools…Spinning-platter
hard drives are defragged nightly…The system "backs itself up
automatically every morning"…as Langa says "There’s more, but the
above steps and apps typically provide everything I need to reliably keep my PC
clean, well optimized, stable, and secure"…what's needed to keep the
Chromebook in tip top shape: Reboot it
once a month (give or take)…even that's optional, because…Chromebook users
probably reboot regularly…because it's fast and extends the battery life. My
Chromebook shuts down faster than Windows 7 goes to sleep, and, it cold boots
faster than Windows wakes up from sleeping…a Chromebook is less functional than
a laptop running Windows, OS X or Linux. But, it requires no maintenance…As I
recently suggested, they offer what is probably the safest online experience
out there, making them perfect for financial transactions…”

Google spreadsheets gains
lockdown feature http://googledocs.blogspot.com/2012/08/lock-down-cells-with-protected-ranges.html “Editing with others in real-time makes it
easy to get stuff done in Google spreadsheets in only a matter of minutes. But
with so many people working in the same space, it’s possible to modify a
section that a collaborator didn’t intend to be touched…today, we’re updating
the Named Ranges feature in spreadsheets to let you also protect them. To get
started with Protected Ranges in a shared spreadsheet, highlight the cells
you’d like to protect, right-click, and choose Name and protect range from the
menu. Click through the presentation below to see the feature in action. Along
with the arrival of protected ranges, you can now add colors and patterns when
you apply cell borders in Google spreadsheets. We also updated find and replace
to make it possible to search using patterns (also called regular expressions).
For example, “^[A-Z]+” will find all the cells that start with uppercase letters…”
[Andy – possibly this addresses one of
your concerns about Google Doc spreadsheets, giving you more control over what
other people change – ed.]

Google’s new login tool
makes users with multiple accounts happy http://venturebeat.com/2012/08/11/google-account-chooser/ “Google released Account chooser today, which
lets you easily toggle between Gmail accounts without having to enter and
re-enter your email or password. Account chooser was first noticed by The Next
Web, and undoubtedly excites any person that uses Gmail for both work and
personal accounts. In order to enable the feature, you must first go to this
link, which automatically signs you up if you’re logged into one of your
accounts. That account becomes the default account from which you can add
others. You must click “stay signed in” in order for the feature to work. The
new Gmail login screen is a small box that displays your name, the email
address, and an image if you have one on your account. Multiple sign-on will be
enabled across many of Google’s products, but the company notes that some of
its products are not friendly with the feature yet…”

Google to buy Frommer's
travel guides http://www.latimes.com/business/la-fi-google-frommers-20120814,0,3184864.story “Google Inc. has set its sights on the travel
industry. Looking to attract more advertising dollars, Google said Monday that
it would buy Frommer's travel guides…The proposed purchase would be Google's
second major entry into the travel information business. Last September it
bought Zagat, a well-known restaurant guide. With the acquisition of Frommer's,
another marquee name in travel, Google moves closer to its goal of providing
critiques of every hotel, restaurant and hot spot on Earth. Trustworthy reviews
from Frommer's could give Web surfers more reason to visit Google, which wants
to generate more advertising revenue from the growing online travel industry…According
to research firm EMarketer Inc., the U.S. leisure-travel industry spent $2.56
billion on online ads last year, up 40.6% from a year earlier. Last year
U.S.-based travelers spent more than $100 billion to book trips online…Google
made its first big splash in travel in 2010 with the purchase of flight-data
company ITA Software, which powers flight-booking tools on websites. Last year,
Google launched its own search service for U.S. flights. After its surprise
$151-million purchase of Zagat spearheaded by Marissa Mayer, who is now chief
executive of Yahoo Inc., Google now has an editorial team in New York and
London that oversees writers and photographers around the globe…”

involving more than 20 numbers to make a user yearn for something easier to
remember, and on Monday Google announced that it's begun to deliver just that…companies
and individuals using Google+ will soon be able to claim a custom URL for use
instead of the long, klunky ones they've had so far…Currently, Google+ profile
URLs are ungainly at best. Mine, for example, is the very catchy https://plus.google.com/105492284418862345045/.
With a custom URL, however, users of the popular social network will be able to
use a short, easy-to-remember Web address instead that will link directly to

Improving Google Patents
with European Patent Office patents and the Prior Art Finder http://googlepublicpolicy.blogspot.com/2012/08/improving-google-patents-with-european.html “At Google, we're constantly trying to make
important collections of information more useful to the world. Since 2006,
we’ve let people discover, search, and read United States patents online.
Starting this week, you can do the same for the millions of ideas that have
been submitted to the European Patent Office…Typically, patents are granted
only if an invention is new and not obvious. To explain why an invention is
new, inventors will usually cite prior art such as earlier patent applications
or journal articles. Determining the novelty of a patent can be difficult,
requiring a laborious search through many sources, and so we’ve built a Prior
Art Finder to make this process easier. With a single click, it searches
multiple sources for related content that existed at the time the patent was
filed. Patent pages now feature a “Find prior art” button that instantly pulls
together information relevant to the patent application. The Prior Art Finder
identifies key phrases from the text of the patent, combines them into a search
query, and displays relevant results from Google Patents, Google Scholar,
Google Books, and the rest of the web. You’ll start to see the blue “Find prior
art” button on individual patent pages starting today. Our hope is that this
tool will give patent searchers another way to discover information relevant to
a patent application, supplementing the search techniques they use today…”

New Technology
Means You’ll Never Run Another Yellow Light http://www.wired.com/autopia/2012/08/never-run-a-yellow-light/ “There’s a name for that panic-inducing split
second when a traffic light turns yellow and you have to choose whether to hit
the gas or the brake. It’s called the “dilemma zone,” and a new radar system
promises to make it a thing of the past. TrafiRadar is a new technology from
Belgium-based Traficon. It combines video and radar vehicle detection that can
control a traffic light, holding a yellow until a car has crossed an
intersection. While towns that rely on revenue from red light cameras might be
loath to install the new technology, it could make intersections safer for all.
Currently, drivers in the dilemma zone can either slam on the brakes and risk a
rear-end collision, or run a red light. TrafiRadar can determine whether a
vehicle needs more time to get through an intersection before the yellow light
turns red, and keep all other traffic stopped until that car has crossed. In
addition to TrafiRadar, Traficon also unveiled a new bike detection system that
uses thermal cameras to detect cyclists and give them enough time to cross an
intersection. VIP Bike allows cities to install dedicated turning lanes for
cyclists, and can also count the number of bikes that pass through an
intersection in a given period of time…”

NVIDIA
Announces Kepler-Based Quadro K5000 & Second-Generation Maximus http://www.anandtech.com/show/6140/nvidia-announces-keplerbased-quadro-k5000-secondgeneration-maximus “Typically NVIDIA would launch a high-end GPU
first (e.g. GF100), and use that to build their high-end consumer,
professional, and compute products. Kepler of course threw a wrench into that
pattern when the mid-tier GK104 became the first Kepler GPU to be launched…in
May…NVIDIA has announced their high-end Kepler GPU, GK110, and Tesla products
based on both GK104 and GK110. NVIDIA’s solution to the unusual Kepler launch
situation was to launch a specialized Tesla card based on GK104 in the summer,
and then launch the more traditional GK110 based Tesla late in the year. This
allowed NVIDIA to get Tesla K10 cards in the hands of some customers right away
(primarily those with workloads suitable for GK104), rather than making all of
their customers wait for Tesla K20 at the end of the year…”

Choose the
Right Graphics Card: 2012 http://www.pcworld.com/article/260694/choose_the_right_graphics_card_2012_edition.html “Modern graphics cards are intimidating,
hulking beasts in a world of increasingly tiny PC components. Most of them are
double-wide, occupying two expansion-slot spaces, even though they use only a
single physical slot. Many require two power connectors and beefier-than-average
power supplies…Graphics processing units, or GPUs, are at the heart of these
cards, and their sheer physical size and transistor count--some models have in
excess of 4 billion transistors--help explain why they consume so much power
and require sophisticated cooling systems…Let's take a look at what one of the
latest cards, an Nvidia GeForce GTX 680, looks like when it's stripped bare…The
latest-generation midrange ($200 to $350) and high-end ($400 and up) graphics
cards usually ship with at least 2GB and sometimes 3GB or more of very fast
GDDR5 memory, which has a clock speed of 1500MHz…Now that you've seen what a
card looks like when you rip off its cooling shroud, let's consider the cricual
questions you should answer before buying a graphics card. Here are five
important ones: What types of games do you play?...What other applications do
you run?...What is your budget for a graphics card?...What is your monitor's
display resolution?...What is your PC's performance level?…”

Road-Paver
Concept Lays Asphalt Underneath Traffic
http://www.wired.com/autopia/2012/07/road-paver-concept/ “A recent design school grad has come up with
a machine that can pave roads without shutting down lanes or stopping traffic…Gosha
Galitsky…conceived a machine that would re-pave the road beneath while vehicles
drive up and over. The Dynapac Red Carpet allows cars to pass over, while the
machine re-heats and shapes the road surface using microwaves, a process known
as Hot-in-Place Recycling. Microwaves heat the upper road layer and the asphalt
binding agent, returning the pavement to its original soft state. Rotating
brushes scoop the soft asphalt into a tank where it’s mixed with a small amount
of fresh binder. The mixture gets paved back onto the road while a set of
rollers at the rear compress the new pavement. Since the Red Carpet moves so
slowly, the recycled pavement has time to cool. By the time the machine passes
over, the surface is ready to handle traffic. But its berth only allows for
cars narrower than 78.7 inches to pass through…Galitsky says that road paving
is a process that’s overdue for an evolution: “The machines, materials and
processes we use to construct and maintain our roads today have not changed
significantly since as far as the 1940’s. Since only one basic configuration of
paver exists today, road maintenance has to be done using machines which were
originally constructed for paving new road surfaces…”

keeping fast moving objects centered. The system can track fast-moving objects
with high accuracy, called “amazing.”…This is a pan-tilt system that keeps an
object at the center of the field. The researchers started work based on a
challenge they recognized in the broadcast of major sports events such as the
World Cup and games at the Olympics, where videos that are powerful and of the
highest quality are in demand. In reality, though, they call attention to a
number of limitations in techniques being used to capture the games. “It is
often hard for camera operators to keep tracking their camera's direction on a
dynamic object,” they wrote, such as the player or the ball…“Super slow and
close-up videos of the remarkable player or the ball are thought to be
especially quite valuable. However, camera operators have not been able to do
that.”…the team worked out a camera system that can track fast-moving objects
with something described as a high-speed gaze control device Two mirrors, one
pan, one tilt, can move sixty degrees in approximately 3.5 milliseconds. These
mirrors do the tracking realtime, bouncing images back to a stationary
high-speed camera. The 1ms Auto Pan-Tilt system, as the system is named, gets
its 1ms designation because it uses a 1,000 frame-per-second vision targeting
system…”

No computer
required: The Doxie Go portable document scanner reviewed http://arstechnica.com/gadgets/2012/08/no-computer-required-the-doxie-go-portable-document-scanner-reviewed/ “One thing that struck me when I covered
Consumer Electronics Week back in June was the amount of paper still being
passed around. For all of the tech-savvy people attracted by this exhibition,
the most common way for vendors and journalists to swap information was by
handing out pamphlets, spec sheets, and business cards. Cover a show for a
couple of days and you end up with an unruly stack of paper you can barely jam
into your laptop bag…This is precisely where portable document scanners can
come in handy. Stick a business card into one, and you’ll quickly have a
digital copy that you can use to keep the stacks of paper at a manageable
level. The concept of a small, portable document scanner you can connect to
your computer isn’t new, but the Doxie Go makes it simpler by eschewing the
computer. You can turn this battery-powered scanner on, feed a few documents in
it, and turn it off. The scans will be saved to either its internal memory or a
connected SD card or USB stick, ready to be copied to your computer the next
time you're at your desk. Doxie sent us one of these scanners for review…The
$199 Doxie Go is a 10.5" x 1.7" x 2.2" piece of plastic that
weighs a little less than a pound, similar in size and shape to other mobile
document scanners like those in Fujitsu’s ScanSnap lineup or Brother’s DSmobile
600. Like the scanners in these competing products, the Doxie Go’s maximum
resolution is 600 dpi, but it usually defaults to 300 dpi. By my count, it
takes about 8.5 seconds to make a 300 dpi scan of a standard 8.5” by 11” sheet
of paper, and around 33 seconds to scan the same sheet at 600 dpi…”

Flight, the successor to Microsoft Flight Simulator. No official announcement
at the product’s website yet, but various sources, including Kotaku, have
posted a statement from the company: Microsoft Studios is always evaluating its

“Microsoft Flight,” we will continue to support the community that has embraced
the title and the game will still be available to download for free at http://www.microsoft.com/games/flight/.

James Cameron's 3D China
venture http://www.latimes.com/entertainment/envelope/cotown/la-et-ct-james-camerons-3d-china-venture-20120808,0,5253684.story “…James Cameron and 3D photography specialist
Vince Pace have announced that the Cameron Pace Group (CPG), which specializes
in providing 3D technology, services and consulting to other producers, will
launch a new joint venture in China. The deal, signed Wednesday in Beijing with
the state-owned Tianjin North Film Group and Tianjin High-tech Holding Group,
will see CPG triple in size in the next 18 months, as Cameron and Pace build up
a staff of Chinese workers, overseen by a team that will come in part from the
U.S. and be housed at CPG China’s new studio in the city of Tianjin. Cameron
said this is the first step in a global expansion for the company, part of a
push to make 3D technology the universal film standard worldwide…China, the
fastest-growing world film market, has been quick to embrace 3D cinema.
Cameron's 3D "Avatar" was the biggest-grossing movie of all time in
China, with around two-thirds of the total Chinese revenue of $208 million coming from 3D screenings. The
re-release of Cameron’s “Titanic” in 3D made as much money in China as it made
in all other international markets (excluding North America) combined. Five of
China’s top-grossing films in 2011 -- all of them American made -- were in 3D.
"Transformers 3: Dark of the Moon," for which CPG provided the 3D

their smartphones, Given that virtually every smartphone now has a built-in
music player, we can only assume that this number reflects third-party apps.
Just under half of them have radio apps installed on their phones and 26% have
music store apps. Newer music services like Spotify and Pandora didn’t really

widely different impacts in different market segments around the world. This is
well illustrated with the advent of mobile digital money and the evolution to
an increasingly cashless society. In more advanced economies, this is another
example of once near-magical technologies and apps that we have become so used
to that we often barely notice…in developing economies, mobile digital money
could be the ticket to financial inclusiveness and a higher standard of living

been a spate of articles on the evolution to a cashless society as the use of
mobile devices continues to grow in different ways around the world. The Death
of Cash, Time for Cash to Cash Out?, Visions of a Cashless Society, and Why Cash
is Losing its Currency? are some of the titles…The Death of Cash, published by
Miguel Helft in Fortune, is a good article of the first category. He writes
about his experiences buying a cappuccino at a coffee house in New York City.
He payed for it by simply telling the cashier “Charge it to Miguel,” and was
done. That’s because the coffee house uses Square Register, an iPad-based
digital cash register application, and Helft has Pay with Square, a digital

Tobii's
futuristic gaze-tracking glasses
http://dvice.com/archives/2012/08/eyes-on-with-to.php “…Tobii's glasses are packing the same
pupil-tracking technology that its consumer hardware does, except that instead
of having to sit in front of a laptop, you can just put these things on to get
the same magical effect. In their current incarnation, the glasses aren't
specifically designed as a user interface tool, but are instead set up for passive
gaze tracking and recording. There's no projection or anything: the glasses are
completely see-through. It just tracks your gaze in real-time very, very
accurately. So what's the point if you can't really use the glasses as a
control system? As Tobii explained it to us, there are actually a lot of cool
things that you can do with gaze tracking. For example, you can track where
professional doctors look when they make diagnoses based on X-rays or MRIs, and
then use those data to teach med students what to look for. You can put a pair
of the glasses on veteran police officers while they run through simulations,
and compare their eye movements with those of novice officers running the same
sim to improve training. For fighter pilots (and drivers), wearing the glasses
can detect when they're about to pass out from G forces (or fall asleep). And
it's even valuable for things like treating autism: autistic kids look at rocks
and faces the same way, and detailed gaze tracking may lead to new therapy

How NOT to win friends
and influence people on Kickstarter http://blog.openbeamusa.com/2012/08/11/how-not-to-win-friends-and-influence-people-on-kickstarter/ “…Tangibot is a Makerbot knockoff, started by
a Matthew Bailey Strong from Pleasant Grove, Utah. Matt is asking for a cool
half million dollars (about 1.5x the value of the house he’s living in), to
copy, nut for nut, bolt for bolt, the industry leading 3D Printer, a Makerbot
Replicator, in China. Matt should be honored, because, this is the first time
I’ve made a (refundable) pledge to a project just so I can leave some comments.
Actually, judging from the comments, others,
including MakeZine’s Phillip Torrone, is doing so as well…I understand
that what Matt is doing is legal, within the scope of an OSS license. I am
wondering out loud if he will get sued for trademark violation, as the names
Makerbot and Replicator are trademarked, and he’s using these terms quite
heavily to peddle his knockoff. I also, in no uncertain terms, think what he’s
doing is a complete douchebag move. When I launched OpenBeam 5 months ago…I
realized that even with a traditional business model of patents and patenting
the design of the beam, it would be trivial for a kid in China with an optical
comparator and an afternoon of his time to copy it…So I made the project Open
Source to speed the adaptation, and in doing so, committed myself to doing the
best I can with the project; this project will reflect the best of my
abilities, and I shall create something unique and useful, and add value to the
open source ecosystem…I also recognized that I will be entering a market
competing with others, and I reached out (although never got an answer) to the
Makerbeam folks, and in the case of MicroRAX, I sat down with the son of one of
the MicroRAX principles and showed him what I was doing, before launching the
kickstarter…Will OpenBeam be copied?
Maybe. A good chunk of my time
now is spent trying to figure out ways to ship to other continents
cheaper. I am in the process of getting
quotes in China for a second extrusion die to support my European and
Australian / New Zealand distributors – but I also understand that shipping
costs and such might make spinning up a die on each continent more attractive…”

Arduino board, making it ideal for hardware and firmware tinkerers and lovers
of unique monosynths. But we’ll give it bonus points for two other reasons.
First, it has some really bizarre cases available as add-ons, which look a bit
like punk birdhouses. (Birdhouse squats? Hot rodded bird tenant buildings?)
Second, in a really clever move, they help you troubleshoot hardware issues
with a Flash animation. It could make it clear even to a complete beginner how
to use a multimeter…The Arduino design is significant, because it makes
firmware modification easy for people familiar with that environment. (We’re
not letting 2012 end without some tutorials on how to do this with direct AVR
programming on our MeeBlip, but I definitely see some appeal to working with
Arduino.) To be clear, the way this works is, you can use the Arduino to configure
patches on the SJS – so you’re not programming an Arduino synth, directly. You
also do need an Arduino Uno in order to use the SJS-ONE. The real draw to me is
the quirky sonic character of the thing. On the sound side, they have a nice
approach to the multi-function filter. The whole thing is, indeed, grungy and
squelchy. This thing sounds completely mad, defying the typical rules of synth
engineering, good behavior, and sound “fidelity…”

Proba-1. Orbiting Earth at 720 km altitude, the entire satellite’s volume is
less than a cubic metre. HRC operates alongside Proba-1’s larger CHRIS (Compact
High Resolution Imaging Spectrometer) hyperspectral imager, which takes 15
m-resolution scenes across a programmable selection of up to 62 spectral bands,
from a variety of viewing angles…Operational for more than a decade, Proba-1
was the first in ESA’s series of satellites aimed at providing in-orbit testing
of new space technologies. Smaller than a cubic metre, Proba-1’s many
experiments include the compact HRC that acquires monochromatic images with an
area of 25 sq km. Proba stands for ‘Project for Onboard Autonomy’ – both
cameras are largely autonomous. Controllers at ESA’s Redu station in Belgium
send up the location to be imaged – latitude, longitude and altitude – then the
satellite itself does the rest, lining up its instruments with its target on
the ground. Proba-1 was launched in October 2001 as an experimental mission but
is still going strong, having since been reassigned to ESA’s Earth observation

for genetic conditions, such as Down syndrome, hemophilia, cystic fibrosis, and
sickle-cell disease. Using the CAPS enterprise OpenACC compiler, Shanghai Jia
Tong University researchers accelerated the DNADist application by 16 times on
an NVIDIA Tesla GPU-based system by adding just four simple hints -- known as
"directives" -- to the application code. DNADist, a distance-matrix
application for studying the genetic relationships between various species over
evolutionary history, enables researchers to extract information from sequenced
DNA data by reading nucleotide sequences, which may potentially lead to a
greater understanding of the causes of and treatments for pervasive genetic
diseases. Accelerating the DNADist application allows researchers to study a
significantly larger range of input data and obtain actionable information

GPU Computing Gets Jolt
of Java http://www.hpcwire.com/hpcwire/2012-08-13/gpu_computing_gets_jolt_of_java.html “…specialized programming frameworks like
OpenCL, CUDA or DirectCompute, are the most commonly used methods of tapping
into GPUs for general-purpose computing. With all of these, the parallelization
of the code as well as the processor-specific manipulations that move the
algorithms and data from the CPU to the GPU have to be performed manually. This
presents something of a challenge to the average programmer. Fortunately there
are a number of efforts underway to make GPU programming a more high-level
affair. One of them was described today in UK’s bit-tech, which reported that a
team from Syracuse University has developed a Java compiler aimed at GPU
computing. Phil Pratt-Szeliga, an
instructor at Syracuse University along, with partners Jim Fawcett and Roy
Welch, worked together on the project, known as Rootbeer. In a paper that
describes the technology, they claim that Rootbeer is “the most full-featured
tool to enable GPU computing from within Java to date.” The goal was to develop
a compiler that could that would allow programmers to use standard Java for GPU
computing, without having to know the intricacies of parallel programming or
processor hardware. These are not just bindings to CUDA and OpenCL libraries.
Rootbeer is able to take unmodified Java source and then, under the covers,
automatically parallelize the code and launch the GPU kernel…”
