Microsoft Surface update tweaks performance

Microsoft has issued a firmware for the Surface RT tablet that improves performance, according to reports and anecdotal comments.

On the same day that Microsoft released patches for Windows 8, it is also furnishing a system firmware update for Surface RT along with Windows RT operating system updates.

"Surface is definitely running smoother...App transitions seem snappier," said a reader commenting below a ZDNet article.

A report and a blog post also mention performance improvements when launching apps.

CNET's Surface review last month said performance could be "slow at times."

Fixes listed under a "… Read more

How important is PC processor speed, really?

In the old days, choosing a computer was easy: you bought the one with the fastest processor you could afford. And you knew which processor was fastest (more or less) by its numerical clock-speed rating.

These days it's a lot trickier. Only hard-core techies (and those with the patience to search in Google) know the difference between, say, an AMD A4-3305M and an Intel Core i3-2350M.

And even then, does it really matter? There's a strong argument to be made that processor performance, even in low-cost, entry-level PCs, has reached a level that's good enough for most … Read more

iPhone 5 so far: One road warrior's two-week test

Two weeks in, I've got a better feel for the iPhone 5, both good and bad.

After upgrading from the iPhone 4S to the 5 two weeks ago yesterday, I've been on the road -- bouncing between the east and west coasts. That's plenty of opportunity to test the iPhone 5's mettle.

The good, the bad, the meh:

Wi-Fi: This was the first gotcha. After arriving at my destination in Philadelphia, a Wi-Fi network I needed to access didn't take -- despite working fine with a host of other devices, including an iPhone 3GS and … Read more

Life beyond JavaScript: Google's abuzz over RoboHornet test

Google last night unveiled an early version of RoboHornet, a general-purpose browser speed test that company engineers hope will shed light on something besides just JavaScript.

But Microsoft, maker of Internet Explorer, has derided the tests as not useful.

There are plenty of JavaScript speed tests, Google's new Octane among them, and for good reason: the programming language is used to turn static Web pages into interactive Web apps. But there's more to fast browsing, and Google hopes others will get involved to flesh out RoboHornet with a full suite of tests.

"It's a living, dynamic … Read more

Finally, a chance to tweet to aliens

I have so much to say to aliens, I really doubt I could keep it to 140 characters. But if I'm going to go the "Tweets in Space" route to speak to potential life forms on GJ667Cc, I'll need to keep it short.

The experimental art project will beam real-time tweets toward the exoplanet 22 light-years away during performance events at the 2012 International Symposium on Electronic Art (ISEA) in New Mexico.

"Simply tag your Twitter messages with #tweetsinspace, and your phones, laptops, mobile devices -- anything with an Internet connection -- will be transformed into an alien communicator," says San Francisco new-media artist Scott Kildall, who is collaborating on the networked performance project with Nathaniel Stern, an associate professor in the Department of Art+Design at the University of Wisconsin's Peck School of the Arts. … Read more

Intel to buy key assets from supercomputer maker Cray

Supercomputer maker Cray will sell its interconnect hardware development program and related intellectual property to Intel for $140 million in cash, the two companies announced today.

Up to 74 Cray employees will join Intel, Cray said. The company currently employs approximately 800 people worldwide.

"By broadening our relationship with Intel, we are positioned to further penetrate the [high-performance computing] market," said Peter Ungaro, president and CEO of Cray, in a statement.

Ungaro continued, "This agreement also dramatically strengthens our balance sheet and increases our options for further growth, profitability and creating shareholder value."

Cray said it … Read more

Mozilla contemplates nuking McAfee

The SiteAdvisor add-on for Firefox evaluates search results to let you know how safe a site is to visit before you go there, but one Mozilla engineer says that it drags down Firefox and causes huge memory leaks.

(Update: McAfee announced a fix for later next week, and Mozilla acknowledged it. See below.)

It's just the kind of problem that Mozilla doesn't want to be dealing with as it finds itself knee-deep in an ambitious development plan and surrounded by ever-tougher competition.

Mozilla engineer Nicholas Nethercote wrote a blog post early today in which he recommended that Firefox … Read more

Coming off $2B loss, Sony's Hirai faces 'toughest challenge'

Sony was hit hard during the fourth quarter--its fiscal third quarter--and its incoming CEO knows some serious work will be needed to turn things around.

The electronics giant today announced that it generated 1.82 trillion yen (about $23.4 billion) in revenue in the quarter just ended (PDF), dropping 17 percent year over year. The company posted a loss of 159 billion yen ($2.04 billion), representing a steep decline from the 72.3 billion yen profit it posted during the same period last year.

Sony's earnings were weighed down by a dismal quarter for the company's … Read more
