IBM leaps two hurdles for next-gen memory

IBM has solved two related problems with phase-change memory and now says the fast next-generation data-storage technology will be ready for use in 2016 in servers.

In a paper for the IEEE International Memory Workshop, Big Blue researchers describe how they squeezed two bits of data into each phase-change memory cell rather than just one. Though that's not the first incarnation of this idea, called multilevel storage, the researchers said they've made it practical by sidestepping a problem called "drift" that otherwise causes data errors the longer data is stored.

The engineering advancements help overcome significant barriers in introducing a technology that holds the potential to significantly transform computer designs. Phase-change memory (PCM), could snuggle up alongside conventional dynamic random access memory (DRAM) to improve computer performance in ways that flash memory so far can't. It's not as fast as DRAM, but IBM says it's 100 times faster at reading and writing data than flash memory, its chief competitor today.

IBM's PCM technology isn't yet ready for real-world use, but the improvements in multilevel storage and drift tolerance means the technology should be competitive in 2016 for the server applications IBM has in mind, said Haris Pozidis, one of the IBM Research paper authors.

"Our main application, being in the server business, is enterprise storage and memory applications," Pozidis said. "In the consumer market, the most important attribute is cost per bit. In enterprise applications, the most important attributes are speed, because [PCM will be] sitting close to the main memory where there are lots of transactions per second, and the endurance of device. We must make sure the device can write and read many numbers of times." … Read more

U.S. seeks exemption to EU aviation CO2 plan

Reuters

The United States demanded today that the European Union exempt U.S. airlines from an EU law widening carbon permits to aviation, hardening a standoff over a scheme due to start in 2012.

After talks in Oslo, the European Union insisted it would not back down on its unilateral plan to penalize greenhouse gas emissions from planes taking off and landing in the European Union as part of efforts to slow climate change.

"We clearly stated our strong objections to the EU plans on both legal and policy grounds," a U.S. administration official told a telephone news conference after talks between EU and U.S. negotiators.

In the strongest public criticism of the EU carbon scheme to date by President Barack Obama's administration, Washington said U.S. airlines should be exempt from greenhouse gas penalties.

The official, who spoke on condition of anonymity like all other delegates, said the EU was using "the wrong way to pursue the right objective" of slowing global warming that is predicted to cause more droughts, floods, and rising sea levels.

The European Commission said there were no plans to back down, echoing… Read more

Honeycomb 3.1 (first take): Small changes, missed opportunities

When Google announced Android 3.1 Honeycomb was coming to the Xoom last week, I was pretty excited. Honeycomb's already a great tablet OS, so any improvements could only add to its functionality and efficiency. Unfortunately the version 3.1 update was released over the air and was rolled out in spurts. Our Xoom didn't receive its update until earlier this week. Google detailed changes to expect, but I wanted to check and see just how well some of them were implemented.

Browser Aside from a few annoyances, I thought the Chrome browser in Honeycomb 3.0.1 … Read more

Cell phones causing decline in bee numbers?

A recent scientific study suggests that bees are significantly disturbed when mobile phones are used in close proximity to the furry critters. The study may shed light on why the bee population is in decline globally.

As bees can communicate through sound, the experiment at the Swiss Federal Institute of Technology observed any changes to the noises the insects made when active mobile phones were placed in their hive. The results were quite worrying.

Take a photo once a day

Everyday is an app designed to make it easy to snap a photo every day to chronicle how your look changes over time. Made popular by various bloggers and other photography types, the concept is you snap a picture of yourself everyday, then after a significant amount of time (6 months? One year?), you can show a movie of gradual changes to your appearance.

With the Everyday app, most of the work is done for you. You can set up reminders so that you get a push notification to take today's picture. After you take your first picture the … Read more

U.N.: Renewables could be 80 percent of energy by 2050

Reuters

Renewable sources such as solar, wind, and hydropower could fulfill almost 80 percent of the world's energy demand by 2050 with the right policies, according to a U.N. report which won backing from governments today.

The 26-page study, by the U.N.'s Intergovernmental Panel on Climate Change (IPCC), broadly matched a draft written by scientists. It was approved by government delegates at talks in Abu Dhabi.

Environmental groups hailed the report as a guide to the shift from fossil fuels to combat climate change, a process set to cost trillions of dollars. But they said some draft … Read more

AT&T still No. 1 on dropped calls, but iPhone owners seem satisifed

The AT&T iPhone 4 drops more calls than Verizon's model, yet customers of both carriers seem about equally satisifed, according to a ChangeWave Research study released yesterday.

Questioning a total of 4,068 mobile phone users in a survey completed March 28, ChangeWave found that 82 percent of the Verizon Wireless iPhone 4 owners polled and 80 percent of those using AT&T's iPhone 4 said they were very satisified overall. The Verizon iPhone has been on the market since February, when it ended AT&T's long run of exclusivity for the Apple … Read more

AT&T changes early upgrade and no-commitment pricing

AT&T has increased its early upgrade and no-commitment prices for new phones. Early upgrade pricing affects those who want to get a new handset but are not eligible for an upgrade, while no-commitment pricing affects those who do not want to sign a new contract.

For early upgrades, pricing will go up to $50 for smartphones and $10 for other phones. For no-commitment deals, fees will increase by $50 for smartphones except for the iPhone and $20 for other phones.

AT&T spokesman Seth Bloom told CNET in an e-mail that "as mobile devices become more … Read more

Rename huge batches of files easily

This awkwardly named utility (now known as "Better Rename" in the Mac App Store) can be extremely useful in some very specific situations. Anyone who needs to rename large batches of files on a daily basis--especially Web developers and anybody working with lots of photos or audio files--should definitely check out A Better Finder Rename. Most of what this app does can also be done with the Finder and Automator, but nowhere near as quickly nor as easily.

ABFR offers a huge number of renaming options, everything from modifying text and adding sequence numbers to changing formats and … Read more

Dual monitor access to menus

MenuEverywhere helps power users--and anyone else with multiple monitors, or just a very large monitor--get quick access to an application's menu bar, from any window or any screen.

MenuEverywhere works in the background, with a slim CPU footprint and an extensive set of preferences to control its appearance and behavior. You can set MenuEverywhere to put a complete menu bar on the top of every window associated with an app (for example, the Photoshop menu bar on every Photoshop window, no matter which monitor the window appears in), or you can have it just place a single "Menu&… Read more
