Can Plastic Replace Silicon?

Can plastic materials morph into computers? A research breakthrough recently published brings such a possibility closer to reality.

Researchers are looking at the possibility of making low-power, flexible and inexpensive computers out of plastic materials. Plastic is not normally a good conductive material. However, researchers said this week that they have solved a problem related to reading data.

The research, which involved converting electricity from magnetic film to optics so data could be read through plastic material, was conducted by researchers at the University of Iowa and New York University. A paper on the research was published in this week’s Nature Communications journal.

More research is needed before plastic computers become practical, acknowledged Michael Flatte, professor of physics and astronomy at the University of Iowa. Problems related to writing and processing data need to be solved before plastic computers can be commercially viable.

Plastic computers, however, could conceivably be used in smartphones, sensors, wearable products, small electronics or solar cells, Flatte said.

The computers would have basic processing, data gathering and transmission capabilities but won’t replace silicon used in the fastest computers today. However, the plastic material could be cheaper to produce as it wouldn’t require silicon fab plants, and possibly could supplement faster silicon components in mobile devices or sensors.

“The initial types of inexpensive computers envisioned are things like RFID, but with much more computing power and information storage, or distributed sensors,” Flatte said. One such implementation might be a large agricultural field with independent temperature sensors made from these devices, distributed at hundreds of places around the field, he said.

The research breakthrough this week is an important step in giving plastic computers the sensor-like ability to store data, locally process the information and report data back to a central computer.

Mobile phones, which demand more computing power than sensors, will require more advances because communication requires microwave emissions usually produced by higher-speed transistors than have been made with plastic.

It’s difficult for plastic to compete in the electronics area because silicon is such an effective technology, Flatte acknowledged. But there are applications where the flexibility of plastic could be advantageous, he said, raising the possibility of plastic computers being information processors in refrigerators or other common home electronics.

“This won’t be faster or smaller, but it will be cheaper and lower power, we hope,” Flatte said.

Heartbleed Hits Oracle

Oracle issued a comprehensive list of its software that may or may not be impacted by the OpenSSL (secure sockets layer) vulnerability known as Heartbleed, while warning that no fixes are yet available for some likely affected products.

The list includes well over 100 products that appear to be in the clear, either because they never used the version of OpenSSL reported to be vulnerable to Heartbleed, or because they don’t use OpenSSL at all.

However, Oracle is still investigating whether another roughly 20 products, including MySQL Connector/C++, Oracle SOA Suite and Nimbula Director, are vulnerable.

Oracle determined that seven products are vulnerable and is offering fixes. These include Communications Operation Monitor, MySQL Enterprise Monitor, MySQL Enterprise Server 5.6, Oracle Communications Session Monitor, Oracle Linux 6, Oracle Mobile Security Suite and some Solaris 11.2 implementations.

Another 14 products are likely to be vulnerable, but Oracle doesn’t have fixes for them yet, according to the post. These include BlueKai, Java ME and MySQL Workbench.

Users of Oracle’s growing family of cloud services may also be able to breath easy. “It appears that both externally and internally (private) accessible applications hosted in Oracle Cloud Data Centers are currently not at risk from this vulnerability,” although Oracle continues to investigate, according to the post.

Heartbleed, which was revealed by researchers last week, can allow attackers who exploit it to steal information on systems thought to be protected by OpenSSL encryption. A fix for the vulnerable version of OpenSSL has been released and vendors and IT organizations are scrambling to patch their products and systems.

Observers consider Heartbleed one of the most serious Internet security vulnerabilities in recent times.

Meanwhile, this week Oracle also shipped 104 patches as part of its regular quarterly release.

The patch batch includes security fixes for Oracle database 11g and 12c, Fusion Middleware 11g and 12c, Fusion Applications, WebLogic Server and dozens of other products. Some 37 patches target Java SE alone.

A detailed rundown of the vulnerabilities’ relative severity has been posted to an official Oracle blog.

Dell Unveils Laptop/Tablet Hybrid

Dell unveiled a new 11.6-in. screen rugged laptop that has literally has a twist — the screen can rotate 180 degrees to turn the device into a tablet.

At first, the Latitude 12 looks like a laptop. But within the display panel, the screen rotates 180 degrees and the laptop turns into a tablet once placed on the keyboard.

The new Latitude 12 laptop is part of a new Rugged Extreme line of laptops, which also includes the Rugged Extreme 14. The new laptops are robust and can withstand six-foot drops and remain protected from extreme weather conditions.

The laptops have hard covers that add a layer of protection, but also make the products heavy. The Latitude 12 Rugged Extreme weighs 2.72 kilograms with a four-cell battery, while the 14-in. counterpart weighs 3.54 kilograms with a six-cell battery and no optical drive.

The laptops can also withstand solar radiation, “explosive atmosphere” and weather ranging from -20 degrees to 145 degrees Fahrenheit (-29 degrees to 63 degrees Celsius), according to specifications provided by Dell. The products are targeted at field workers like emergency responders and the military, and will compete against Toughbook rugged laptops from Panasonic.

The Latitude 12 rugged laptop has a starting price of $3,649, while the Latitude 14 begins at $3,499. The laptops will ship next month.

The hybrid design in Latitude 12 has been borrowed from the company’s XPS 12 Ultrabook Touch, which has a 12.5-inch screen that can similarly flip to turn the laptop into a tablet. The resistive touch screens on both laptops can show images at a resolution of 1366 x 768 pixels.

The laptops will have storage options of up to 512GB solid-state drives. Users can configure the laptop with Intel’s latest fourth-generation Core processorscode-named Haswell. The laptops will come with either Windows 8.1 or 7, or Ubuntu Linux operating systems.

Other features include support for up to 16GB of DRAM, Wi-Fi and Gigabit Ethernet through a connector. The laptop also has USB 3.0, USB 2.0, VGA and HDMI ports. Mobile broadband and docking are available as options.

Virtru Goes Office 365

Virtru has added Microsoft’s Office 365 and Outlook Desktop services to its growing list of compatible email platforms available on its encryption product.

The company, headquartered in Washington, D.C. and launched in January, is targeting people using major email providers who want stronger privacy controls for more secure communication.

The service is designed to be easy to use for end users who may not have the technical gumption to set up PGP (Pretty Good Privacy), a standard for signing and encrypting content.

Virtru is compatible with most major webmail providers, including Google’s Gmail, Yahoo’s Mail and Microsoft’s Outlook webmail, which replaced Hotmail.

Emails sent using Virtru through those services would look like gibberish, providing a greater degree of privacy. Law enforcement or other entities would not be able to read the content unless they could obtain the key.

Virtru uses a browser extension to encrypt email on a person’s computer or mobile device. The content is decrypted after recipients receive a key, which is distributed by Virtru’s centralized key management server.

Although Virtru handles key management, the company is working on a product that would allow that task to be managed on-site for users, as some administrators would be uncomfortable with another entity managing their keys.

Virtru has said it put aside funds to contest government orders such as a National Security Letter or law enforcement request that are not based on a standard of probable cause.

Cisco Goes To The Cloud

Cisco Systems Inc will offer cloud computing services, pledging to spend $1 billion over the next two years to make a foray into a market currently dominated by the world’s biggest online retailer Amazon.com Inc, the Wall Street Journal reported.

Cisco said it will spend the amount to build data centers to help run the new service called Cisco Cloud Services, the Journal reported.

Cisco, which mainly deals in networking hardware, wants to take advantage of companies’ desire to rent computing services rather than buying and maintaining their own machines.

Enterprise hardware spending is dwindling across the globe as companies cope with shrinking budgets, slowing or uncertain economies and a fundamental migration to cloud computing, which reduces demand for equipment by outsourcing data management and computing needs.

“Everybody is realizing the cloud can be a vehicle for achieving better economics (and) lower cost,” the Journal quoted Rob Lloyd, Cisco’s president of development and sales as saying.

“It does not mean that we’re embarking on a strategy to go head-to-head with Amazon.”

Microsoft Corp last year said it was cutting prices for hosting and processing customers’ online data in an aggressive challenge to Amazon’s lead in the growing business of cloud computing.

Cisco could not be immediately reached for comment by Reuters outside regular U.S.business hours.

HP Unveils 3D Plan

Hewlett-Packard Co will unveil plans to enter the commercial 3D-printing arena in June, saying it has resolved a number of technical issues that have hindered broader adoption of the high-tech manufacturing process.

Chief Executive Meg Whitman told shareholders the company will make a “big technology announcement” that month around how it will approach a market that has excited the imagination of investors and consumers.

Critics have accused the sci-fi-like technology of being over-hyped and still too immature for widespread consumer adoption.

Industry observers have long expected HP, the largest of several printer-making companies from Canon to Xerox, to eventually get into the business. Whitman said HP’s inhouse researchers have resolved limitations involved with the quality of substrates used in the process, which affects the durability of finished products.

“We actually think we’ve solved these problems,” Whitman told an annual shareholders meeting. “The bigger market is going to be in the enterprise space,” manufacturing parts and prototypes in ways that were not possible before.

“We’re on the case,” she said without elaborating.

HP executives have estimated that worldwide sales of 3D printers and related software and services will grow to almost $11 billion by 2021 from a mere $2.2 billion in 2012.

The nascent 3D-printing market is now dominated by a number of smaller players like MakerBot, a unit of Stratasys that is concentrating on selling more affordable devices to consumers.

Contract manufacturers like Flextronics however already use the technology to help craft prototype parts or devices for corporate clients.

“HP is currently exploring the many possibilities of 3D printing and the company will play an important role in its development,” CTO and HP Labs director Martin Fink said in a February blogpost on HP’s website.

“The fact is that 3D printing is really still an immature technology, but it has a magical aura. The sci-fi movie idea that you can magically create things on command makes the idea of 3D printing really compelling for people.”

Web Pioneer Calls For Bill of Rights

The inventor of the world wide web, Tim Berners-Lee, voiced his support for bill of rights to protect freedom of speech on the Internet and users’ rights after leaks about government surveillance of online activity.

25 years since the London-born computer scientist invented the web, Berners-Lee said there was a need for a charter like England’s historic Magna Carta to help guarantee fundamental principles online.

Web privacy and freedom have come under scrutiny since former U.S. National Security Agency contractor Edward Snowden last year leaked a raft of secret documents revealing a vast U.S. government system for monitoring phone and Internet data.

Accusations that NSA was mining personal data of users of Google, Facebook, Skype and other U.S. companies prompted President Barack Obama to announce reforms in January to scale back the NSA program and ban eavesdropping on the leaders of close friends and allies of the United States.

Berners-Lee said it was time for a communal decision as he warned that growing surveillance and censorship, in countries such as China, threatened the future of democracy.

“Are we going to continue on the road and just allow the governments to do more and more and more control – more and more surveillance?” he told BBC Radio on Wednesday.

“Or are we going to set up something like a Magna Carta for the world wide web and say, actually, now it’s so important, so much part of our lives, that it becomes on a level with human rights?” he said, referring to the 1215 English charter.

While acknowledging the state needed the power to tackle criminals using the Internet, he has called for greater oversight over spy agencies such Britain’s GCHQ and the NSA, and over any organizations collecting data on private individuals.

He has previously spoken in support of Snowden, saying his actions were “in the public interest”.

Berners-Lee and the World Wide Web Consortium, a global community with a mission to lead the web to its full potential, have launched a year of action for a campaign called the Web We Want, urging people to push for an Internet “bill of rights” for every country.

Is Samsung Ditching Android?

Samsung appears to have delivered a huge snuff to Android OS maker Google. Samsung’s new smartwatch Gear 2 and Gear 2 Neo, the sequels to the poorly reviewed original Galaxy Gear are going to ship without Android.

Instead, the new Gears run Tizen, another open source operating system that Samsung, Intel, and others are working on. It is starting to look like Samsung wants to distance itself from its reliance on Google for software and services.

Samsung’s official reason is that Tizen has better battery life and performance. The new Gears can get up to an extra two days of battery life by running Tizen, even though they have the same size battery. The Galaxy Gear barely made it through a day on one charge.

To be fair Android isn’t optimized to run on wearable devices like smart watches, but Samsung didn’t want to wait around for Google to catch up. It was clearly concerned about beating Apple to market. So far Apple has not shown up.

What Do Smaller Controllers Mean?

If you want a wearable Internet of Things, the electronics have to be as tiny and as energy efficient as possible. That’s why a new microcontroller by Freescale Semiconductor is noteworthy.

The company has produced the Kinetis KLO3 MCU, a 32-bit ARM system that is 15% smaller than its previous iteration but with a 10% power improvement.

Internet of Things is a buzzword for the trend toward network-connected sensors incorporated into devices that in the past were standalone appliances. These devices use sensors to capture things like temperatures in thermostats, pressure, accelerometers, gyroscopes and other types of MEMS sensors. A microcontroller unit gives intelligence and limited computational capability to these devices, but is not a general purpose processor. One of the roles of the microcontroller is to connect the data with more sophisticated computational power.

The Kinetis KLO3 runs a lightweight embedded operating system to connect the data to other devices, such as an app that uses a more general purpose processor.

Kathleen Jachimiak, product launch manager at Freescale, said the new microcontroller will “enable further miniaturization” in connected devices. This MCU is capable of having up to 32 KB of flash memory and 2 KB of RAM.

Consumers want devices that are light, small and smart. They also want to be able to store their information and send it to an application that’s either on a phone or a PC, Jachimiak said.

This microcontroller, at 1.6 x 2.0 mm, is smaller than the dimple on a golf ball, and uses a relatively new process in its manufacturing, called wafer level chip scale packaging. The process involves building the integrated package while the die is still part of a wafer. It’s a more efficient process and produces the smallest possible package, for a given die size.

Software Glitch Hits Prius

Toyota is recalling nearly 1.9 million Prius hybrid automobiles globally in order to fix a software glitch that could damage transistors and cause a loss of power.

Some 700,000 of the Priuses are in the U.S., according to a statement. Another 997,000 are in Japan, 130,000 in Europe and the remainder in other places around the world, according to media reports. Toyota didn’t immediately respond to a request for confirmation of those details on.

Toyota plans to tweak software in the Priuses for the motor/generator ECU (engine control unit) and the hybrid control ECU. The current settings “could result in higher thermal stress in certain transistors, potentially causing them to become damaged,” Toyota said. “If this happens, various warning lights will illuminate and the vehicle can enter a failsafe mode. In rare circumstances, the hybrid system might shut down while the vehicle is being driven, resulting in the loss of power and the vehicle coming to a stop.”

Toyota is also recalling about 260,000 2012 RAV4 compact sport utility vehicles, 2012-2013 Tacoma trucks and 2012-2013 Lexus RX 350 SUVs in the U.S., the company said Wednesday.

Toyota will apply an update to skid control ECU software on cars in this recall to fix an “electronic circuit condition” that could cause the vehicles stability control, anti-lock braking systems and traction control function to shut down intermittently, Toyota said. However, in the event of such a failure the standard brakes will still work, according to the company.

No accidents or injuries have been reported in connection with the software problems, Toyota said. The software update will be applied free of charge at local dealers.
