Khan Academy Inspires
Flip of Doctor-Patient Relationship Model http://techcrunch.com/2012/03/06/khan-academy-inspired-flip-of-doctor-office-visit/ “…the Khan Academy has impressed many of us
and inspired teachers to flip the classroom lecture/homework model on its head
as described in the video below. Doctors are now recognizing similar value in
videos for their patients…In fact, we may not have a choice with the
ever-increasing shortage of primary care physicians…individuals forget as much
as 80-90% of what a doctor tells them. One of the nice things about Khan
Academy is learners with different skill levels can watch the videos in
different ways. Some may get it just watching it once while others may want to
replay the video over a few times before a concept sinks in…Perhaps because Dr.
Wendy Sue Swanson was a teacher before she was a pediatrician, she was
naturally drawn to using her videos and blogs to benefit her patients’
families…the shortcomings of an office visit…is heavily driven by the billing
needs versus a long-term focus on a patient’s overall health…Many doctors,
particularly in primary care, are unhappy about the way they have been practicing
and are unleashing their own creativity…So much of our present care delivery is
rote and could be practiced online or provided via video/blog/text. And that
the ‘real medicine,’ the service and the relationship or helping people in
moments of anxiety and indecision are rare and undervalued. That oddly enough,
there is simply no time in the day to do what matters most…”

Microsoft: OnLive's
Windows-on-iPad service violates license http://arstechnica.com/business/news/2012/03/microsoft-onlives-windows-on-ipad-service-violates-licensing-policy.ars “Gaming company OnLive…recently launched a
service bringing a Windows 7 desktop, complete with Microsoft Office 2010, to
iPad and Android tablets…There's just one problem: Microsoft says it's not
properly licensed. The software giant is apparently asking OnLive for some cash
in exchange for the right to continue the service, which is still working
today…Microsoft has licensing options for partners who want to provide Windows
in virtual desktop settings, but those options apparently don't cover the
OnLive service as it exists today…Brian Madden, who writes extensively about
desktop virtualization, wrote that "based on everything we know about
Microsoft licensing, this [the OnLive service] should be in clear violation of
Microsoft's policies…”

Infographics For
Everyone: Visual.ly Launches First Automated Tool http://techcrunch.com/2012/03/12/infographics-for-everyone-visual-ly-launches-first-automated-tool-out-of-beta/ “…Visual.ly, which offers an online tool to
create instant visualizations of data, is launching its first public product
out of beta. The service will let users take publicly-available data such as
information from a Twitter hashtag or a Facebook feed, and then select a
template (currently five, with each having two to three variations within it)
to instantly visualize it. It will also team up with third parties and brands
to offer other data feeds to users: one, for example, will involve sports
statistics from ESPN. While infographics seem like the kind of thing that would
mostly be the domain of number-crunching analysts and journalists, created for
consumption by the wider public, the use of Visual.ly’s beta — launched last
year — testifies to there being a bigger audience for actually making these
pictures firsthand…”

Gigabit Internet for $70:
the unlikely success of California's Sonic.net http://arstechnica.com/tech-policy/news/2012/02/gigabit-internet-for-80-the-unlikely-success-of-californias-sonicnet.ars “…While some other cities can also brag about
gigabit access, in this Sonoma County town it costs only $69.95 a month. The
service comes courtesy of Sonic.net, the18-year-old Internet provider based in
the neighboring city of Santa Rosa. And Sonic even throws in two phone lines
with unlimited long-distance calling when you sign up…almost none of the few
dozen residents on Florence Avenue bother with the highest-end gigabit service,
though. And why should they? Sonic's everyday 100 Mbps fiber offering costs
just $39.95 a month, the same price Sonic used to charge for its 20 Mbps DSL
connections (It includes unlimited phone, too.) Compare Sonic’s 100 Mbps price
to the two better-known area options for broadband—Comcast's Xfinity Extreme
105 Mbps service runs $199.95 a month, while AT&T's U-Verse tops out at 24
Mbps for $49.95…Sonic kicked off this buildout on favorable ground: a reasonably
dense neighborhood in Sebastopol, a compact town of 7,397 that may be
best-known as the home of tech-book publisher O'Reilly…But why did Sonic also
offer gigabit access at only twice the price of its 100 Mbps service? Said
Jasper: Why not? "The cost differential between a customer who's connected
at all and one who's connected at one gigabit…is nominal." Calling the
$69.95 service "a headline product," he noted one key reason for
Sonic to offer it: because others can't…”

Bell Labs innovations
underpin a breakthrough commercial 400 gigabit-per-second chip http://www.stockhouse.com/News/USReleasesDetail.aspx?n=8444567 “…Alcatel-Lucent…is introducing…a new chip
for fiber optic networks that offers double the capacity, and four times the
speed of today's networks…the Alcatel-Lucent Photonic Service Engine supports
400 gigabit per second…data transmission speeds on optical networks…unabated
growth of broadband, mobile data and cloud-based services has presented a major
challenge for service providers that need to find ways to keep costs in check
while dramatically expanding the capacity of their networks…The versatile 400G
PSE chip can be deployed in a broad range of network configurations - from
metro to regional to ultra-long haul - and transmit wavelengths over existing
or new photonic lines…”

Up against the Wall!
Should district be allowed to demand middle-schooler's Facebook password? http://redtape.msnbc.msn.com/_news/2012/03/13/10657012-up-against-the-wall-should-district-be-allowed-to-demand-middle-schoolers-facebook-password “A 12-year-old Minnesota girl was reduced to
tears while school officials and a police officer rummaged through her private
Facebook postings after forcing her to surrender her password…The girl, whose
identity is withheld in the lawsuit, came home "crying, depressed, angry,
scared and embarrassed" after she was intimidated into divulging her login
information by a school counselor and a deputy sheriff, who arrived in uniform,
armed with a Taser…The student now fears that the school could make her give up
her passwords at a moment's notice, at any time, for any reason," the
lawsuit claims. It also alleges that
password prying is standard practice at the Minnewaska Middle School…Officials
at the Minnewaska Area School District…say the ACLU's version of events is
"one-sided," and that the school acted to "prevent
disruption,"…The lawsuit raises the complicated -- and quite unsettled --
legal quandary that balances students' constitutional rights with schools' needs
to maintain order and a positive educational environment. For example, can
schools punish students who publicly criticize school officials on their own
time using social networks?…” http://redtape.msnbc.msn.com/_news/2012/03/06/10585353-govt-agencies-colleges-demand-applicants-facebook-passwords “If you think privacy settings on your
Facebook and Twitter accounts guarantee future employers or schools can't see
your private posts, guess again. Employers and colleges find the treasure-trove
of personal information hiding behind password-protected accounts and privacy
walls just too tempting, and some are demanding full access from job applicants
and student athletes. In Maryland, job seekers applying to the state's
Department of Corrections have been asked during interviews to log into their
accounts and let an interviewer watch while the potential employee clicks
through wall posts, friends, photos and anything else that might be found
behind the privacy wall…Student-athletes in colleges around the country also
are finding out they can no longer maintain privacy in Facebook communications
because schools are requiring them to "friend" a coach or compliance
officer, giving that person access to their “friends-only” posts. Schools are
also turning to social media monitoring companies with names like UDilligence
and Varsity Monitor for software packages that automate the task. The programs
offer a "reputation scoreboard" to coaches and send "threat
level" warnings about individual athletes to compliance officers…”

Why online security is
taxing our brains http://www.reuters.com/article/2012/03/08/us-websecurity-memory-idUSBRE82719N20120308 “…trying…to keep up with all the passwords
and security questions…just to log onto…personal accounts…sometimes it feels
like a losing battle. It's a battle millions of consumers can identify with.
For a while it was just your mother's maiden name, then your first pet, the
street you grew up on or the make and model of your first car. As passwords and
security questions multiply, so does the potential for things to go wrong,
possibly locking you out of your own life. Unless you're a savant with total
recall, you need a system to manage that morphing body of login credentials
necessary to navigate your virtual life…His answer? An elaborate Excel spreadsheet
that's password-protected. Others go more old-school, like executive coach
Darla Arni in Slater, Missouri. "I have an entire notebook that I keep all
my passwords in, but its pages are filling up" and becoming increasingly
disorganized, says the 55-year-old…Some smartphone apps, like RoboForm, Keeper
Password, and PasswordWallet, can help consumers manage password overload…To be
sure, going through several layers of authentication is a good thing for
consumers, helping reduce the risk of increasingly sophisticated hackers
gaining access to their accounts and emptying them out…It's what helps us
identify fraudsters in Eastern Europe who have stolen your online credentials…”

Yahoo Uses Words of
Facebook’s Zuckerberg to Poke Him http://allthingsd.com/20120312/worst-but-first-yahoo-uses-words-of-facebooks-zuckerberg-to-poke-him-in-patent-lawsuit/ “On the sixth page of its just-filed patent
lawsuit against Facebook, Yahoo quotes the social networking company’s CEO and
co-founder Mark Zuckerberg: “Getting there first is not what it’s all
about.”…Yahoo contends…Zuckerberg has “conceded that the design of Facebook is
not novel and based on the ideas of others,”…it’s an attempt to hit home one
point: We were here first and we have more patents…Of the 10 patents Yahoo is
using in the 19-page lawsuit, filed today in California, the company said: “For
much of the technology upon which Facebook was based, Yahoo was there
first…Facebook’s entire social network model, which allows users to create
profiles for and connect with, among other things, persons and businesses, is
based on Yahoo’s patented social networking technology,”…So what does Yahoo
want for this alleged free ride? Triple damages and to enjoin Facebook from
operating by using said patents. Given the scope of the patents Yahoo said it
has, that means it wants Facebook to essentially close down…”

Eavesdropping Antennas
Can Steal Your Smart Phone's Secrets http://www.technologyreview.com/communications/39855/ “The processors in smart phones and tablets
leak radio signals that betray the encryption keys used to protect sensitive
data…Gary Kenworthy of Cryptography Research held up an iPod Touch on stage and
looked over to a TV antenna three meters away. The signal picked up by the
antenna, routed through an amplifier and computer software, revealed the secret
key being used by an app running on the device to encrypt data…The antenna was
detecting radio signals "leaking" from the transistors on the chip
inside the phone performing the encryption calculations…"[This] antenna is
not supposed to work at this frequency, and it's been in someone's attic for
years and is a bit bent," said Kenworthy, a principal engineer at
Cryptography Research. "You could build an antenna into the side of a van
to increase your gain—well, now you've gone from 10 feet to 300 feet." Kenworthy
and Benjamin Jun…demonstrated how a loop of wire held close to two models of
smart phone could pick up their secret keys…The apps used in Jun and
Kenworthy's demonstrations were of their own design, because it would be
"bad manners" to demonstrate sniffing keys from other company's
apps…the researchers have shown privately that they can eavesdrop on encryption
keys from any app or mobile software…”

Duqu Trojan used
'unknown' programming language http://malware.cbronline.com/news/duqu-trojan-used-unknown-programming-language-kaspersky-070312 “…Researchers working for Kaspersky Lab have
discovered that the Duqu Trojan, believed to have been written by the people
behid the Stuxnet worm, was partly written using a previously unknown
programming language…Researchers analysed the Payload DLL and found one section
was written in an unknown language - it is this section that communicates exclusively
with the C&C server, Kaspersky said. They have labelled this section the
Duqu Framework. The Duqu Framework is not written in C++ and it's not compiled
with Microsoft's Visual C++ 2008, "but is definitely
object-oriented," Igor Soumenkov wrote on the company's blog. "The
Duqu Framework appears to have been written in an unknown programming
language."…we are 100% confident that the Duqu Framework was not
programmed with Visual C++. It is possible that its authors used an in-house
framework to generate intermediary C code, or they used another completely
different programming language,"…CEO Eugene Kaspersky said that it
"seems the state behind Duqu sponsored the development of a new
[programming] language…”

U.S. reportedly warns
Apple, e-book publishers about price-fixing http://www.chicagotribune.com/news/nationworld/la-fi-tn-department-of-justice-warns-apple-major-publishers-possible-lawsuits-for-ebook-price-fixing-20120308,0,5119376.story “The U.S. Justice Department has warned Apple
Inc. and five top book publishers that lawsuits over alleged e-book price
fixing might be in the offing…the Justice Department has told publishers and
the Cupertino tech giant that lawsuits could be filed accusing the companies of
colluding to keep e-book prices high for both Apple users and rivals such as
Amazon and Barnes and Noble. Some publishers "have held talks to settle
the antitrust case and head off a potentially damaging court battle," the
Journal said. "If successful, such a settlement could have wide-ranging
repercussions for the industry, potentially leading to cheaper e-books for

SXSW 2012: British ad
agency turns homeless into wifi hotspots http://www.telegraph.co.uk/technology/news/9139054/SXSW-2012-British-ad-agency-turns-homeless-into-wifi-hotspots.html “A well known British advertising agency has
sparked outcry within the technology community attending the South by Southwest
Interactive conference in Austin, Texas, by turning homeless people into wifi
hotspots. Bartle Bogle and Hegarty (BBH) has launched a “charitable
experiment”…whereby it equips homeless people with a 4G MiFi device to create a
pay-as-you-go wifi hotspots for attendees. However, the experiment…has been
criticised by many attendees and technology writers as “tasteless” and
“thoughtless”. Attendees need to stand near the homeless volunteer in order to
access the wifi, which many have described as just "awkward"…BBH’s Homeless
Hotspots website frames the initiative as an attempt to “modernise the Street
Newspaper…Wired magazine has described Homeless Hotspots as something which
sounds like it is out of a “darkly satirical science-fiction dystopia…BBH has
defended the initiative, which, at first many people on Twitter thought was a
hoax…homeless people are…given a t-shirt to wear, which says: I’M [FIRST NAME],
A 4G HOTSPOT, SMS HH [FIRST NAME] TO 25827 FOR ACCESS, www.homelesshotspots.org...there’s
an insane amount of chatter about this, which…in many ways is very good for the
homeless people…these people are no longer invisible…We are not selling
anything. There is no brand involved. There is no commercial benefit whatsoever…Each
of the Hotspot Managers keeps all of the money they earn. The more they sell
their own access, the more they as individuals make…”

has entered the "post-PC era," opting instead for the more
Windows-friendly "PC-plus" phrasing. But Ray Ozzie, Microsoft's
former chief software architect, has little doubt that the world has moved on.
"Why are we arguing? Of course we're in a post-PC world," Ozzie
said…To Ozzie, though…the market for devices that do general computation is
going to continue to expand. And there's plenty of opportunity for companies
that understand how to create devices consumers want…”

New iPad all about
graphics http://news.cnet.com/8301-13924_3-57392624-64/new-ipad-why-quad-core-graphics/ “Apple has just elevated the graphics chip to
superstar status…the new iPad has a quad-core graphics processing unit
(GPU)…Anandtech cites graphics chip technology from Imagination (PowerVR
SGX543MP4) and CPU tech from ARM (Cortex A9)…Translation? The new iPad's
graphics chip--which is based on Imagination's PowerVR tech--is basically a
quad-core version of the dual-core graphics chip in the iPad 2. That's where
Apple gets the two-fold performance increase…Apple is focusing on the GPU
because it needs to devote all of the chip real estate it can to transistors
that push around an amazingly pixel-dense display--which crams a resolution of
2,048x1,536 into a 9.7-inch display…But good graphics aren't only necessary for
gaming. High-octane graphics silicon can boost performance on other tasks,
including multimedia (video decode) and productivity (iPhoto or Photoshop)…for
these reasons, Apple may have just promoted the GPU to No.1 chip status…” http://www.readwriteweb.com/archives/why_the_new_ipad_is_so_huge_for_apple.php “…new iPad introduction was Apple's most
important event of the year…the iPhone is still a bigger business for Apple…But
the iPhone is just Apple's small sliver of the giant phone market. The iPad,
meanwhile, is a green field - a totally new market that Apple is building and
defining. And so far, it has it almost to itself…the iPad maintained its lead
as the best tablet on the market in terms of hardware, software, and
ecosystem…And don't overlook the importance of the price-cut iPad 2, now
starting at $399. By shaving $100 off the cheapest iPad's price, Apple has
significantly expanded the iPad's addressable market…"We think that iPad
is the poster child of the post-PC world," Apple CEO Tim Cook said…Apple
could potentially sell 80 million iPads this year, about twice as many as it
did last year…At an average price around $550, that's about $45 billion in
sales - about the same amount as all of Apple generated in 2009…” http://news.cnet.com/8301-13579_3-57392727-37/four-takeaways-from-apples-resolutionary-ipad/ “…Someday, sometime, Apple is going to
stumble, and maybe the competition will finally take advantage of the misstep
to close the gap. That day's not yet on the horizon. With the newest iPad
featuring a sharper screen, the high-resolution 2048x1536-pixel Retina Display,
as well as faster wireless connectivity, rapid-response touch-screen control
and quad-core graphics, Apple has widened its lead in the tablet market…Middle
managers are showing up for meetings with iPads in tow. Factory managers go
about their floor checks carrying around iPads. Doctors and hospital
administrators are incorporating the iPad into work flow. Similar stories
abound, offering anecdotal evidence that something's afoot…”

HomeSnap Is Not A Boring
Real Estate App http://techcrunch.com/2012/03/08/homesnap-is-not-a-boring-real-estate-app/ “Sawbuck Realty, an online real estate
broker, has just launched a new app called HomeSnap which lets you discover
information about any home nationwide just by taking a photo of it. Using a
combination of mobile phone sensors to determine location and orientation as
well as MLS and public records data, HomeSnap can tell you everything about a
home, including how many square feet it has, number of bedrooms/bathrooms,
estimated price and more. And it can do so even if the house is not on the
market…Currently, it has over 90 million homes in its database… “So many of the
real estate apps are boring and utilitarian, explains Wolcott. “We looked at
things like Shazam – things where you want to show your friends, and they say
‘how does that work?’ – and we tried to make something like that for
homes.”…the app uses the iPhone’s sensors, like the accelerometer, gyroscope,
and GPS, to determine where you are and what you’re looking at… “The real
idea,” says Wolcott, “is to be kind of magical. You just take a picture, and it
knows what you’re looking at…”

their devices for shopping, from researching products and reviews, to comparing
prices, finding retail locations, and redeeming coupons. And retailers are
responding with mobile apps and websites designed to attract smartphone
shoppers…Nielsen’s detailed analysis of smartphone usage reveals that retail

maps API, a lot of companies have switched to OpenStreetMaps…Apple has joined
the club, using OSM in the new iPhoto for iPad and iPhone. But…Apple didn’t
bother to credit the creators of these maps, and is using two-year-old,
out-of-date information…all they’ve done is render Open Street Map data with
their own stylesheet, miscategorised the status of some ways, conveniently
forget to include any copyright attribution, and pass it off as their own…The
folks behind OSM were a little more tactful in their blog post about the
discovery: The OSM data that Apple is using is rather old (start of April 2010)
so don’t expect to see your latest and greatest updates on there. It’s also
missing the necessary credit to OpenStreetMap’s contributors; we look forward
to working with Apple to get that on there…”

Google Fiber Missouri LLC the authority to build a video service network…On
Feb. 17, Google sought franchises to offer video service in Kansas City and
Kansas City, Kan…The application to the Kansas Corporation Commission cited
Internet-based TV offerings to residences. That application remains pending;
commissioners have 30 days from the Feb. 17 filing date to approve it…Google
still is exploring what product offerings will be available when it launches
Google Fiber in Kansas City. She said the video franchise licenses were a

ARM unveils
world’s most efficient 32-bit processor
http://www.geek.com/articles/chips/arm-unveils-worlds-most-efficient-32-bit-processor-20120313/ “…chances are you have a chip based on an ARM
design inside your phone and/or tablet. But it’s not just the high-performance
gadgets we use everyday that require processors, everything from home
appliances to the vehicles we travel in and the medical equipment that monitors
us contain a myriad of chips too. Today, ARM has unveiled the world’s most
energy efficient 32-bit processor, and it’s promising to open the way for many
more very low power, always-connected devices…The new chip is called the ARM
Cortex-M0+ and has a 32-bit architecture built using a 90nm process, which
helps to keep costs down…Significantly, the M0+ offers both performance and
power saving gains over the previous generation chip it the replaces: the
Cortex-M0. But more importantly, ARM has developed a 32-bit processor that uses
a third of the energy typical 8-bit and 16-bit processor require…Even though
ARM is using a 90nm process for the M0+, it still manages to produce a chip
that measures just 1mm x 1mm…Depending on the device, when coupled with a
battery pack this new chip could go years before the battery is depleted. It
truly opens up a deploy-and-forget mentality for intelligent sensors…”

IBM drills
holes into optical chip for terabit-per-second speed http://arstechnica.com/business/news/2012/03/holey-chip-ibm-drills-holes-into-optical-chip-for-terabit-per-second-speed.ars “IBM researchers have built a prototype
optical chip that can transfer a terabit of data per second, using an
innovative design requiring 48 tiny holes drilled into a standard CMOS chip,
facilitating the movement of light. Much faster and more power-efficient than
today's optics, the so-called "Holey Optochip" technology could
enhance the power of supercomputers…With the Holey Optochip, Schow said
"our target is the bandwidth that interconnects different processors in
the system—not the processor talking to its memory, but a processor talking to
another processor in a large parallel system."…That base chip has all the
electronic circuit functions to complete the optical link. So it's got drivers
that modulate vertical cavity lasers and receiver circuits that convert
photocurrent from a detector into a usable electrical signal." Drilling
holes into the chip lets IBM use industry-standard, 850-nanometer vertical
cavity surface emitting lasers (VCSEL), and photodiode arrays, both soldered on
to the chip. The holes allow optical access through the back of the chip to the
transmitter and receiver channels, making it more compact…”

out. The tech we do get never seems to work quite as seamlessly as the
futurists suggest. And yet we're still making remarkable technical progress;
networking in general, and the Internet in particular, have only begun to
transform our homes. Here are five basic technologies that will soon prove

Microsoft
unveils universal translator that converts your voice into another language http://www.extremetech.com/extreme/122083-microsoft-unveils-universal-translator-that-converts-your-voice-into-another-language “Microsoft Research has shown off software
that translates your spoken words into another language while preserving the
accent, timbre, and intonation of your actual voice. In a demo of the prototype…Rick
Rashid, Microsoft’s chief research officer, says a long sentence in English,
and then has it translated into Spanish, Italian, and Mandarin…it’s remarkable
how the three translations still sound just like Rashid. In order for the
translation system to do its work it needs about an hour of training, which
allows it to create a model of your voice. This model is then mushed into
Microsoft’s standard text-to-speech model for the target translation
language…Once the training period is out of the way, there’s no reason that
translation couldn’t be performed in real time on a smartphone, or
near-real-time…”

The New Cable-TV Guy:
Intel http://online.wsj.com/article_email/SB10001424052702304450004577277732222512596-lMyQjAxMTAyMDEwMjExNDIyWj.html# “Intel Corp. is developing an Internet-based
television service that it hopes to sell to U.S. consumers, a strategic shift
by the chip maker as it sets its sights on the crowded pay-TV business. Intel
has for several months been pitching media companies on a plan to create a
"virtual cable operator" that would offer U.S. TV channels nationwide
over the Internet in a bundle similar to subscriptions sold by cable- and
satellite-TV operators…Intel wouldn't provide Internet access, which subscribers
would obtain separately. The TV offering would use Intel technology, and in at
least some scenarios under consideration, would use Intel's name. In its
presentations to media companies, Intel says it is making its own set-top box
to carry the TV service, and it has demonstrated an interface for users to
browse programs…The new effort would mark a big shift for Intel…Intel's
maneuvers come as the broader television business undergoes a major shift, with
people spending more time watching video on the Internet and mobile
devices…Hoping to get more of its chips into consumer living rooms, Intel has
for years made the case that more processing power and better software are
needed for services that appeal to consumers. But many of its efforts in the field,
including a hardware effort called Viiv, and past partnerships with Hollywood
content partners, have been scuttled…”

that would compete against Square, Intuit, Verifone and others…The dongle…will
allow small business owners to process credit card swipes from a smartphone,
similar to Square, Intuit’s GoPayment and Verifone’s PAYware. The potential
move…would fall in line with PayPal’s recent strategy to bring its payment
services into physical stores. It’s working with a host of partners to bring
its in-store system to bigger retailers including Home Depot, which is
launching the service in more than 2,000 locations…The in-store system works

Among Online
Entrepreneurs, Subscriptions Are All the Rage http://www.nytimes.com/2012/03/08/business/smallbusiness/selling-online-products-by-subscription-is-all-the-rage.html?_r=1&pagewanted=all “…If you’re a dog owner like I am, you go out
and buy food every three or four weeks…But you usually don’t realize you need
it until you’re out.” Mr. Zhardanovsky, 34, was well aware that an online pet
supply store, Pets.com, had been one of the more celebrated flameouts of the
dot-com bubble. But…Mr. Zhardanovsky’s plan was to sell pet food on a
subscription basis. He figured that other pet owners had experienced the same
frustrations…and might be willing to sign up for a monthly delivery service…We
had an overwhelmingly positive response from our customers who wanted to sign
up for the service…Customers who sign up to receive regular deliveries of pet
food can determine how much they get and how often it comes…In its first month,
July 2010, the company shipped about 60 orders; by January of this year, that
number had leapt to 27,000. In 2011, PetFlow exceeded $13 million in revenue —
with 60 percent of its sales coming on a subscription basis…subscription models
are, in so many ways, the holy grail of business…lately, more businesses have
come up with creative ways to use the Internet to sell products that have not
traditionally been sold by subscription. H.Bloom…sells flowers by subscription;
Trunk Club sells clothing by subscription…Amazon encourages customers to place
standing orders for products like power bars or paper towels…It is not hard to
see the appeal of recurring revenue, but some of the benefits may be less
obvious. “This is the best business model you can ever have because we can
place inventory purchases against future sales…That predictability allows…lower
inventory levels and…better deals with suppliers…A subscription model allows
you to establish long-term relationships with customers…Subscription models and
recurring revenue also tend to impress investors…he noticed we had such a
strong connection with our community of customers and suggested a
subscription-based model…subscription models are a great way to build lifetime
relationships with our customers…The change to a subscription model had an
immediate impact; Ms. Kim’s business grew more in the five months after she
made the switch than it had in the previous three years combined…I think
subscription models work best in two instances,” he said. “Where the product is
a necessity or when it’s an absolute passion…” [potential opportunity discussion topic for NEW NET meeting: what

Doc Brown's DeLorean from Back to the Future. This thing looks exactly like
Doc's ride from the movie, and can hover off the ground quite well, despite the
uneven weight distribution of the car body. Clearly, where it's going, it
doesn't need roads…not only does it fly, but it looks awesome, with those LED
headlights and taillights, body details and glowing wheels. It's even got a
tiny little Mr. Fusion on the back - though it gets its power from a Lithium

OCD:
Hackerspace Detroit http://metrotimes.com/culture/the-nerdy-playhouse-1.1281937 “…OmniCorpDetroit, a self-described
hackerspace located in the heart of Eastern Market. Pushing past the completely
tired "computer-hacking" connotation, the term refers to a
cooperative where members pool financial and material resources as well as
ideas…It's about creating, rebuilding, experimenting and inventing together — a
notion that members refer to as "hacking."…OCD guy and moped mechanic
AJ Manoulian remembers millions of extension cords running everywhere because
there was originally only one plug for the airy, 8,000-square-foot space. At
least junk removal was easy, as garbage was thrown out a second-story window
into a garbage bin below...One of the founding members, Jeff Sturges…secured
finances and the lease on the building, which was once a cold storage
warehouse. The initial funds were gathered from all co-founders, each of whom
contributed between $200 and $2,000 for a start-up pot of about $5,000. There
was no grant funding, total DIY from day one. They rent from the folks at Rocky
Produce, who've been "really supportive." A year and a half after OCD
opened its doors, every corner of the cavernous warehouse is occupied and in-process.
The first-floor workshop houses a bunch of dusty mopeds and myriad old machines
— a table saw, welder and lathe being the easiest to identify…Upstairs,
computer geeks and artists are lost in their respective programming and
painting. There is a full sewing station, a 3-D printer, and neat rows of desks
cluttered with computer screens, oscilloscopes and other electronics. A
well-stocked DJ booth sits behind a wall of speakers made from hacked-up radio
components from an abandoned music school…Most of these tools and machines have
been donated or are shared between members, with a few larger purchases having
been voted on as a group and purchased from communal OCD funds…” http://www.detroityes.com/mb/showthread.php?9639-Hackerspace-Detroit “…If you seek the bright side of Detroit,
look no further than the budding Eastern Market hackerspace collective
OmnicorpDetroit…When one enters a hackerspace the thought can easily cross one's
mind, "What use on earth could any of these projects ever have?" Yet
when in the actual surround of the space and feeling the energy exuding from
the all the brightness and inquisitiveness the thought becomes,
"Something, no many things, very significant and important are certain to
arise from here…” [check out this article for some great pictures of OmniCorpDetroit –

incredibly fine details is now possible using “two-photon lithography”. With
this technology, tiny structures on a nanometer scale can be fabricated.
Researchers at the Vienna University of Technology (TU Vienna) have now made a
major breakthrough in speeding up this printing technique: The
high-precision-3D-printer at TU Vienna is orders of magnitude faster than
similar devices (see video). This opens up completely new areas of application,
such as in medicine…The 3D printer uses a liquid resin, which is hardened at
precisely the correct spots by a focused laser beam. The focal point of the
laser beam is guided through the resin by movable mirrors and leaves behind a
polymerized line of solid polymer, just a few hundred nanometers wide. This high
resolution enables the creation of intricately structured sculptures as tiny as

Lessons learnt from Local
Motors’ take on the open-hardware revolution http://miter.mit.edu/article/open-source-cars-are-here-lessons-learnt-local-motors%E2%80%99-take-open-hardware-revolution “…The only attractive segment of the
automotive market is getaway vehicles for VCs who hear the word ‘automotive’
and need to flee the scene as hysterically as possible…The epitome of Japanese
efficiency, Toyota, spends three to five years and billions of dollars to
produce a new automobile model. This industry is not for everyone. But Jay
Rogers…founded Local Motors to make open-source cars. The company developed an
online platform for crowd sourced car design and developed a unique
micro-factory for rapid local manufacturing…we are not taking on the car
industry as a whole. Rather, we are taking on the problems with car
manufacturing. There are so many technologies for cars, but they are not making
their way to production and testing quickly…Rogers believes that this model of
open innovation is not appropriate for every field, but it can be applied to
any field that scores high on two scales: number of users and number of
creators. This simple paradigm makes sense, and when you think about it, it
suddenly poses opportunities in other apparently obese industries…it’s not
enough just to have many people able to do this and many people interested in
the product – it has to have a large, real impact on the user’s life…The hitch
with crowd-sourcing is that nobody wants to do the uninteresting dirty work…There
is no such thing as un-moderated open sourcing. Standard-writing is a critical
part of the process and regulation is a very real part of the car industry…Local
Motors took a big piece of regulation from the Air Resources Board to court and
won unanimously…Can an open-sourced jalopy survive against the lean mean
driving machines of Detroit, Germany and Japan? Local Motors’ showstopper, the
Rally Fighter, argues that it can. It is a sleek all-terrain vehicle with…stunning
design and extreme durability…The Rally Fighter originated from a web design
tournament and was chosen as the first design for production…This design made
it through not only because of its popularity within the open community, but
because it was identified as buildable yet unique…Specs for the Rally Fighter
are: 6.2 liter, V8 engine and 430 horsepower (at 5900 rpm), 424 lbft (at 4600
rpm). The final version of the Rally Fighter uses composite panels for the
doors, body and inner shells. There is
no paint on the Rally Fighter…We wanted desert drivers to absolutely love it,
whereas North-Easterners will probably find it inappropriate, but we will get
to them soon, with our next models…It took the Rally Fighter 18 months to go
from initial concept to production. Traditional manufacturers need three to
five years…Local Motors plans to further reduce this time to 12 months for its
next models…the open-source model allows for rapid development to a stage that
is “good enough to get to customers.” Great customer ideas are incorporated in
the next production vehicles…To manufacture cars locally and save on expensive
shipping fees, Local Motors designed a micro-manufacturing plant, implementable
globally…Customers come for a few days to build their own car with the
assistance of Local Motors trained staff. No mechanical or engineering skills
are required…The customer is fully involved in the assembly of the car – from
frame alignments and engine calibration to break system and dashboard placement…this
concept of having the customer emotionally involved in the creation of the car
is…part of a recent trend of shifting the power balance from traditional
manufacturers…to the end customer, who is recently figuring out the benefits
and accessibility of hands-on production. “Our vision is for everyone to be
able to build these models everywhere, but in the short run, the best solution
is this micro factory we developed, which is operated like a local agency in
different areas by people who are interested in being a nexus of local
manufacturing…”

Open source hardware:
Announcing a new licence http://blogs.computerworlduk.com/commons-law/2012/03/open-source-hardware-announcing-a-new-licence/index.htm “Open hardware is coming of age. I'm
currently working on projects as diverse as open source cars, open source
boats, open source wind turbines and open source electronics. A problem is that
there are only two open licences designed for hardware: the CERN open hardware
licence and the TAPR open hardware licence. Both of these are copyleft
licences, and attempt to impose the same licence terms on any distribution of
the original hardware, in a form similar to GPL: so called
"copyleft". I'm not convinced that copyleft is the right way to go
for hardware…Hardware and software are different. It costs zero to replicate
software, but will always cost something to replicate hardware, even if you
have unrestricted access to the blueprints. The upshot of this is that the cost
differential between adopting the GPL and designing around it (for software) is
vastly greater than the cost differential in circumventing a copyleft hardware
licence. This is one reason why hardware copyleft is not a great idea. Another
reason is that it's relatively easy to circumvent any hardware copyleft licence…”

An open-source
robo-surgeon http://www.economist.com/node/21548489 “…Blake Hannaford and his colleagues…are
about to release a flock of medical robots with wing-like arms, called Ravens,
in the hope of stimulating innovation in the nascent field of robotic surgery.
Robot-assisted surgery today is dominated by the da Vinci Surgical System, a
device that scales down a surgeon’s hand movements to let him make tiny
incisions. That leads to less tissue damage, and thus a quicker recovery for
patients. Almost 2,000 da Vincis have been made, and they are used in about
200,000 operations a year around the world…the da Vinci is…immobile and weighs
more than half a tone…and it costs $1.8m, which puts it beyond the reach of all
but the richest institutions. It also uses proprietary software. Even if
researchers keen to experiment with new robotic technologies and treatments
could afford one, they cannot tinker with da Vinci’s operating system. None of
that is true of the Raven. Originally developed for the American army by Dr
Hannaford and Jacob Rosen…as a prototype for robotic surgery on the
battlefield, it is compact, light and cheap (relatively speaking) at around
$250,000…it is also the first surgical robot to use open-source software. Its
Linux-based operating system lets anyone modify and improve the original code,
creating a way for researchers to experiment and collaborate…At Harvard, Rob
Howe and his team hope to use a Raven to operate on a beating heart, by
automatically compensating for its motion. At the moment, heart surgery
requires that the organ be stopped and then restarted…Warren Grundfest is
working on ways to give the robot a sense of touch that is communicated to the
operator. Pieter Abbeel and Ken Goldberg…will try teaching the robot to operate
autonomously by mimicking surgeons. And Dr Rosen himself will work on ways to
get human and robotic surgeons to work together…”

yet, just wait. Multicore processors and on-chip GPUs are already on the
desktop…You may have started your parallel programming career with
multiprocessor systems. Clusters and symmetric multiprocessing systems are
commonly used as servers, and high-level task partitioning has wrung a lot of
performance out of them. The next wave of parallelism arrived with multicore
processors. All the major CPU vendors are now delivering multiple cores on
single chips. Your app won’t perform any better unless you use special
libraries and algorithmic techniques to rewrite your code to take advantage of
multiple cores. Tools to ease this process are now routinely included in
vendors’ development systems. A variant of multicore processing is now being
implemented on GPGPU systems. GPGPU stands for “general-purpose computing on
graphics processing units.” Now that hardware vendors are building chips that
contain both general-purpose CPUs and GPUs on the same silicon, you can farm
out certain kinds of tasks to the GPU. Researchers are finding that a wide
variety of programming problems are vulnerable to the GPGPU approach, but you may
not recognize your code once you’ve adapted it to the new architecture. Say
