The Library Vs. The Internet: What The Numbers Say

Why the Internet Hasn’t Killed the Library (Yet)

David A. Barclay | April 28, 2016

US institutions of higher education and US local governments are under extraordinary pressure to cut costs and eliminate from institutional or governmental ledgers any expenses whose absence would cause little or no pain.
In this political climate, academic and public libraries may be in danger. The existence of vast amounts of information—a lot of it free—on the internet might suggest that the library has outlived its usefulness.
But has it? The numbers tell a very different story.

For several generations, academic librarians were primarily preoccupied with the role of their library buildings as portals to information, print and later digital. In recent years, we have reawakened to the fact that libraries are fundamentally about people – how they learn, how they use information and how they participate in the life of a learning community. As a result, we are beginning to design libraries that seek to restore parts of the library’s historic role as an institution of learning, culture and intellectual community.

Innovation In A Social News Startup: The Odyssey

A Startup That Just Raised $25 Million Is Like a College Newspaper on Steroids — and It’s Racking Up 30 Million Uniques a Month

Nathan McAlone | April 27, 2016

There is a graveyard full of startups that have said they want to “democratize” the media business, Odyssey CEO Evan Burns says.
The winning model seems so tantalizingly within reach: Build a big platform that allows a lot of fresh voices to contribute. No more gatekeepers, anyone who wants to write can.
[...] Even so, Odyssey seems to have hit upon one formula for distributed growth in media, and the startup has come out of nowhere to top 30 million monthly uniques using a business model that sits somewhere between a conglomerate of college newspapers and a social network. [...]

Library Book Weeding

Weeding the Worst Library Books

Daniel A. Gross | April 26, 2016

Last summer, in Berkeley, California, librarians pulled roughly forty thousand books off the shelves of the public library and carted them away. The library’s director, Jeff Scott, announced that his staff had “deaccessioned” texts that weren’t regularly checked out. But the protesters who gathered on the library’s front steps to decry what became known as “Librarygate” preferred a different term: “purged.” “Put a tourniquet on the hemorrhage,” one of the protesters’ signs declared. “Don’t pulp our fiction,” another read.

Is It Possible To Stop 3D-Printed Counterfeit Products?

How Do You Stop 3D Printed Counterfeits?

Yu Yuan | April 28, 2016

With 3D printing technologies emerging rapidly and a wide variety of industries looking to adopt 3D printing to streamline production and save on material costs, there is a lot of potential for market expansion. In fact, the research firm Canalys has forecast the 3D printing market, which includes 3D printer sales, materials, and associated services, will continue to experience rapid growth and reach US $16.2 billion by 2018.
[...] Specific concerns exist around preventing counterfeiting, and those are further complicated by a requirement to make 3D print jobs uniform and replicated with 100 percent accuracy no matter what particular printer is utilized. [...]

'Holy Grail' Of Computing

Scientists Hail Latest Quantum Computer As 'Holy Grail' of Computing (+Podcast, ~14 min.)

Elizabeth Hockman | March 29, 2016

Engineers and computer scientists are continually updating computers, making them faster, more powerful.
But a group of researchers have come up with new type of a quantum computer. It’s a device that harnesses the strange laws of physics to solve problems more complex than any our current computers are capable of tackling.
This quantum computer, according to a paper just published in the journal Science, is composed of just five atoms. And particularly exciting for researchers: they believe it is easily scalable to larger versions.

As The Maker Movement Evolves

Small, Inexpensive Computers Are Changing the Maker Movement

Joseph Neighbor | April 15, 2016

The cost and size of microprocessors and hardware prototyping boards have fallen dramatically in recent years making it possible to buy fully functioning computers with Wi-Fi and Bluetooth connectivity for under $10. This trend has supported a surging global “Maker Movement” consisting of DIY software designers, artists, musicians, designers tinkerers, and entrepreneurs who are using these devices as a means to wildly imaginative ends. The resulting innovation has enormous implications for the emerging Internet of Things, which promises to make everything from shoes to traffic grids “intelligent” and connected.

Unsending Your Text Message

You Can Now 'Unsend' a Text Message before Someone Reads It

Bethan McKernan | April 17, 2016

Everyone has sent a drunk or angry text you regretted later. And even if you haven't, you've definitely sent a message to the wrong person by accident.
Now a new app called Privates (eww, we know) is claiming it can recall messages if you've already pressed send.
It only works before the recipient opens the message, so you have to act pretty quickly.
There are three levels - Mild, Wild and Insane - which will delete messages after 24, 12 or three hours.

How Easy Is It To Hack Mobile Phones?

Phone Hacking Fears and Facts

The lack of security built into phone networks leaves callers vulnerable to snooping, but the growth of encrypted communications will help protect privacy

Larry Greenemeier | April 20, 2016

Apple’s ongoing standoff with the government over passcode-protected iPhones is still raising unprecedented alarms over smartphone security and privacy. For example, a 60 Minutes segment this week outlined several ways hackers can hijack phones from anywhere in the world to listen in on private conversations, read e-mails and even use phone cameras to spy on their owners. That hacking method exploited an unsecured, decades-old telecom protocol called Signaling System 7 (SS7) to tap into U.S. Rep. Ted Lieu’s (D–Calif.) mobile phone and listen to his conversations. Lieu gave his permission for the demonstration and now wants the House Committee on Oversight and Government Reform to investigate the problem.

Makerbot Outsourcing Production Of Its 3D Printers

MakerBot Is Done Making Its Own 3D Printers

Ryan Whitwam | April 27, 2016

Just a few years ago, MakerBot was a hot new startup that seemed like it was about ride a wave of consumer interest in 3D printing to the top of the technology world. Things have not exactly gone to plan in that respect. MakerBot has announced that it plans to halt production of its own in-house 3D printers going forward. This isn’t the end, but it’s definitely a recalculation for the company.
There will still be “MakerBot” 3D printers, but the company has contracted with a Florida-based electronics manufacturing company called Jabil to manufacture the hardware.

Mind Control?

Think Mind Control Is Science Fiction? Think Again (+Video)

Scientists have figured out how to use our brainwaves for everything from racing drones to restoring the function of paralyzed limbs.

Evan Thomas | April 26, 2016

Researchers are getting better at harnessing brain signals. These days, you can strap on a headset and control a drone with nothing but your thoughts.
"We have a computer program that you look at. We tell you, 'Think forward. Think about pushing a chair forward.' So we learn to navigate the drone based on your brain patterns for specific things you're thinking about," said University of Florida's Juan Gilbert.
And as mind-reading gets easier, there are more and more things that can be mind-controlled.

An example of how the brain to brain interface demonstration would look.

"In this photo, UW students Darby Losey, left, and Jose Ceballos are positioned in two different buildings on campus as they would be during a brain-to-brain interface demonstration.

[Abstract: We describe the first direct brain-to-brain interface in humans and present results from experiments involving six different subjects. Our non-invasive interface, demonstrated originally in August 2013, combines electroencephalography (EEG) for recording brain signals with transcranial magnetic stimulation (TMS) for delivering information to the brain. We illustrate our method using a visuomotor task in which two humans must cooperate through direct brain-to-brain communication to achieve a desired goal in a computer game. The brain-to-brain interface detects motor imagery in EEG signals recorded from one subject (the “sender”) and transmits this information over the internet to the motor cortex region of a second subject (the “receiver”). This allows the sender to cause a desired motor response in the receiver (a press on a touchpad) via TMS. We quantify the performance of the brain-to-brain interface in terms of the amount of information transmitted as well as the accuracies attained in (1) decoding the sender’s signals, (2) generating a motor response from the receiver upon stimulation, and (3) achieving the overall goal in the cooperative visuomotor task. Our results provide evidence for a rudimentary form of direct information transmission from one human brain to another using non-invasive means.])

Copyright As A Form Of Censorship

Copyright Maximalists And Lobbyists Celebrate Vancouver Aquarium Censoring Critical Documentary With Copyright

Mike Masnick | April 26, 2016

We've written many times about how copyright is frequently used for censorship, and just recently we wrote about law professor John Tehranian's excellent article detailing how copyright has a free speech problem, in that people using copyright to censor has become more common and more brazen. Whenever we write this kind of thing, however, I get pushback from copyright maximalist lobbyists and lawyers, who insist that no one really wants to use copyright for censorship purposes, but merely to "protect" their works.
I'm finding those claims difficult to square with the following story, which I only found out about because the Copyright Alliance -- a front group for the big legacy entertainment companies, and put together by some well known lobbyists -- tweeted out a link to a story on a blog by Hugh Stephens, entitled A Whale of a (Copyright) Tale.

Pay Phones Are Relics, But There's Still Demand for Them

Daniel Wheaton | April 26, 2016

Pay phones, those relics of a not-so-distant past, remain hidden among us, and many of them still work just fine.
They are quickly becoming a rare sight: Statewide, the number of pay phones has decreased by more than 70% since 2007. But there are still thousands left.

There are somewhat less than 500,000 pay phones in the United States. [See http://www.apcc.net/i4a/pages/index.cfm?pageid=40]. New York City Pay Phones To Become WiFi Hotspots: Source: http://www.outsidethebeltway.com/new-york-city-pay-phones-to-become-wifi-hotspots/

DNA Study Of Tens Of Thousands With Autism

Study to Gather DNA of Tens of Thousands with Autism

[The Washington Post, in: www.abqjournal.com] | April 25, 2016

Scientists funded by the Simons Foundation Research Initiative on Thursday announced the launch of an online research initiative that aims to gather DNA and other information from 50,000 people with autism and their family members.
Although the cause of the social communication disorder is unknown and believed to be a mix of environmental and genetic factors, scientists have identified some 50 to 70 genes that may play a role in the condition. Some estimate that a total of 350 or more could be involved.

Can China reboot its manufacturing industry—and the global economy—by replacing millions of workers with machines?

Will Knight | April 26, 2016

Inside a large, windowless room in an electronics factory in south Shanghai, about 15 workers are eyeing a small robot arm with frustration. Near the end of the production line where optical networking equipment is being packed into boxes for shipping, the robot sits motionless.
“The system is down,” explains Nie Juan, a woman in her early 20s who is responsible for quality control. Her team has been testing the robot for the past week. The machine is meant to place stickers on the boxes containing new routers, and it seemed to have mastered the task quite nicely.

Biographer of To Kill a Mockingbird author finds unsigned piece on quadruple murder at centre of Truman Capote’s In Cold Blood

Dalya Alberge | April 25, 2016

The discovery of an earlier manuscript from the US novelist Harper Lee was the publishing sensation of last year but now her biographer, Charles J Shields, believes he has found another previously unknown Lee text – a feature article about a notorious real-life quadruple murder.
The piece was written for the March 1960 issue of the Grapevine, a magazine for FBI professionals, just months before she was to publish her classic novel, To Kill a Mockingbird. It was unsigned, but Shields’s detective work uncovered evidence which appears to confirm its true authorship.

Plant Intelligence Is Powering This Artificial 'Life'

This Cybernetic Lifeform Is Powered by Plant Intelligence (+Video)

emiko.jozuka@vice.com | April 25, 2016

Cities like London can often feel like urban jungles with scarce amounts of green spaces.
But researchers from the Interactive Architecture Lab at University College London are exploring a future scenario where “cybernetic lifeforms” that are “half garden and half machine” roam our urban cityscapes, co-existing alongside us.
Hortum machina B is a robotic geodesic sphere covered in plants.

The robotic “brain” consists of an array of electrodes that allow it to monitor the physiological responses of the plants to their environment, such as to reactions to stimuli including light, humidity, and temperature. Linear actuators then move the sphere by shifting its centre of gravity.

Salvador Dali In The Brain

Dali Helps Scientists Crack Our Brain Code

Scientists at Glasgow University have established a world first by cracking the communication code of our brains

Kenneth Macdonald | April 21, 2016

Pioneering research in the field of cognitive neuroimaging has revealed how brains process what we see.
The work has been led by Prof Philippe Schyns, the head of Glasgow's school of psychology, with more than a little help from Voltaire and Salvador Dali.
How Dali's mind worked is a matter of continuing conjecture. But one of his works has helped unlock how our minds work. Or more precisely, how our brains see.

3D Printing Used To Hack "Secured" Keys

3D Printing Hackers Cracked “Secured” Keys (+Video)

Suzanne Crockett | April 21, 2016

[Blogger's note: The video is 44 min. and highly recommended for a full explanation of security risks with "Pin Tumbler Locks".]
In an exciting development in Australia – or worrying, depending on which side of the lock you’re on – a group of hackers in Melbourne has demonstrated their ability to use 3D printed keys to open security locks with highly restricted keyways. And how did they do it? By accessing the designs of the locks on publicly available patent sites.
According to our research “Restricted keys are controlled by limiting manufacture to expensive specialist locksmiths who require licenses and specific machinery to produce the keys”. Hackers have benefited from data becoming purely digital. I presume that with objects becoming both physical and digital, I like to say “digical”, hackers will enter our lives by the front door, reaching our cars, our fridges, our sofas, our homes, our bedrooms.

Mini Arduino Wireless Clone: Tiny328

The AAduino

Johan Kanflo | April 13, 2016

I have been using Nathan Chantrell’s Tiny328 for quite some time as my swiss army knife ISM radio node. Now I wanted a more slim ISM node as my setup with a Tiny328 on a breadboard is not very “deployable”. I could of course 3D print a case for the Tiny328 but I have limited access to 3D printers and do not feel I have the time to explore that exciting part of the maker world just yet. This leaves me with finding off the shelf project boxes with a compartment for 2x AA batteries and the “radioduino” (and in an acceptable form factor). That search came up disappointingly, and surprisingly, short. I did have a set of standard eBay AA battery holders and looking at the 3x variant it occured to me. I needed to shrink the radio node, and the AAduino was born.

"The AAduino is an wireless Arduino clone the size of an AA battery with Keystone battery terminals rotated 180° to act as positive and negative terminals. It is meant to go inside a 3xAA battery holder creating a very small wireless node. Powered by an ATMega328p, it is fitted with an RFM69C companion, two DS18B20 temperature sensors and an indicator LED. Included in this repository is the schematics, bill of material and a sample program to test the hardware." Source: https://github.com/kanflo/aaduino
