Google on Thursday announced that it has launched Gmail for Mobile 2.0 for J2ME-supported devices such as the Nokia N95, as well as BlackBerry phones.

Gmail for Mobile 2.0 offers the option to save multiple e-mail drafts in the phone and adds shortcut keys that enable users of phones equipped with QWERTY keyboards to press 'z' to undo, 'k' to go to a newer conversation, and 'j' to go to an older conversation.

* Overall performance improvement: You should experience significant raw speed improvement, smoother scrolling, and no freezing.

* Multiple accounts management: If you have both a Gmail and Google Apps email account, you can easily switch between them quickly. You will no longer have to use two different mobile apps to access personal and work emails.

* Multiple mobile email drafts: You can save multiple email drafts in your mobile phone, so that you can pick and choose what you would like to send later.

* Powerful shortcut keys: If you have a QWERTY phone, you can use shortcut keys. Hit 'z' to undo, 'k' to go to a newer conversation, and 'j' to go to an older conversation. See Menu/Help in the app for more shortcuts.

* Basic offline support: Can't get a signal? Not a problem. You can compose and read your most recent emails even when there is no signal. Also, any outgoing messages will be saved in the outbox on your phone and sent automatically when you're back in coverage.

Looking to get in on the hot low-price notebook market, Lenovo is launching its own bargain laptop offering to compete with small notebooks, such as the MSI Wind and Eee PC. The new laptop, the IdeaPad S10, will ship in October in time for the Christmas season. It will retail starting at $399.

The new notebook features a small footprint with a 10.2 inch LCD screen. The dimensions of the notebooks are 9.8 x 7.2 inches. Weight is 2.4 pounds with the lightest configuration. The notebook is also "super-slim", according to Lenovo, measuring in at approximately 1 inch thin. The device features a slightly-shrunk keyboard which is 85 percent of the size of a standard full-function PC keyboard.

As far as looks, the IdeaPad looks rather slick with a variety of finishes. It can be ordered in "classic white", "bold black", or glossy "ruby red". The white models will have a grayed base.

A couple steps are taken with the design to insure long battery life, a big concern for ultra-portables. First, it uses LEDs to backlight the LCD more effectively than traditional designs. Secondly, it uses Intel's popular Atom processor, in particular the 1.6 GHz N270 with a 945 GSE express chipset.

As the laptop is designed to be used primarily as an internet/word processing machine, connectivity is another major focus. Lenovo added WiFi (b/g), Bluetooth, Ethernet, and an Express Card slot, in order to allow users to get broadband by a variety of methods. The device will also feature 2 USB ports, a 4-in-1 multi-card reader, and a built-in web camera for video messaging. Graphics will be provided by an Intel Integrated Graphics GMA 950 chip.

The notebook will be sold in two different configurations. The first has 512 MB of memory and an 80 GB hard drive. The second, which likely be priced somewhat higher, ups the memory to 1 GB and features a 160 GB hard drive. No solid state drive options have been announced yet. Both configurations come with Windows XP preinstalled, courtesy of Microsoft's stay of retirement on XP for ultra-portables.

The notebooks will be available through a number of major retailers, through Lenovo's partners and direct through Lenovo's website.

Liu Jun, senior vice president, Consumer Business Group, Lenovo states, "IdeaPad netbooks are the latest in a string of recently announced Lenovo products, designed specifically for consumers worldwide and developed through our heritage of technological innovation and exceptional engineering. As rapidly as the technology changes, today’s consumers are looking for mobile products that feature the best of basic computing functions in an extremely compact and affordable form, and Lenovo designed the IdeaPad netbooks for that purpose."

Lenovo also hinted that some countries will have 9 inch screen smaller version available and that Linux preinstalls would also be available in some countries. It is unclear whether the U.S. will get any of these options.

One key factor in the notebook's success or failure will be the battery life. Initial metrics place the life at around 3 hours with 3-cell battery, and up to 6 hours with 6-cell battery, but final measurements remain.

Lenovo's computer lineup, for those unfamiliar, is actual derivative of IBM's former offerings. The Chinese company purchased IBM Personal Computing Division from IBM and rebranded it to launch its computing efforts, back in 2005.

IBM & Los Alamos supercomputer might be as fast as your brain.

Not even a week after the new Roadrunner supercomputer was juiced up and put to work, scientists are hard at work trying to push the machine to its limits. Housed at the Los Alamos National Laboratory, the primary goal of the supercomputer is to model the safety of the United States' aging nuclear weapons stockpile. At over a certified petaflop, the machine renders calculations in a day that would take every person on Earth a calculator and 46 years to accomplish.

A supercomputer of this power will be incredibly useful for modeling things other than nuclear decay and global climate. At over a quadrillion – a million billion – calculations per second, Roadrunner is the only computer on Earth that can keep up with one of the few things more amazing than itself: the human brain.

Los Alamos researchers are putting this power to work with a program dubbed PetaVision. The program was created to model neuron and synapse interaction in the visual cortex of the human brain. The brain uses over a billion neurons and trillions of synapses alone to process the visual information it receives and is one of the most complicated processes known to exist in grey matter.

Supercomputers like Roadrunner bring new possibilities for modeling human recognition systems, and the advances are not likely to stop there. In the past, computers have been unable to flawlessly perform cognitive tasks that the human brain does easily; tasks like picking out a face in a crowd, or detecting oncoming vehicles in traffic. Such a large step up in processing power may enable scientists to breech this difficult wall in mimicry.

The researchers used PetaVision to set a processing record with Roadrunner, spinning up to an astonishing 1.144 petaflop/s. "Just a week after formal introduction of the machine to the world, we are already doing computational tasks that existed only in the realm of imagination a year ago,” explains Terry Wallace, associate director for Science, Technology and Engineering at Los Alamos.

The supercomputer's architecture is based on a hybrid node system. Each node contains two AMD Opteron dual-core and four PowerXCell 8i processers. The PowerXCell CPUs are derived from the same Cell processor used in the Sony Playstation 3 and act as computational accelerators for the Opterons.
