Search for prime numbers or torture your CPU with Prime95

You remember the story of Dr. Jekyll and Mr. Hyde? Well, that's sort of the story of Prime95, too. This mild-mannered mathematics software lets users participate in GIMPS, the Great Internet Mersenne Prime Search. This online project uses the distributed power of many networked PCs (like yours) to search for immense Mersenne prime numbers. Prime95 lets users donate processing power to the nonprofit research project. In the hot hands of overclockers, though, Prime95 becomes an instrument of torture, running stress tests that pinpoint weak links in your system. How you use Prime95 determines its behavior.

The latest mess in Facebook's IPO

In today's show, Facebook shareholders are fuming, Windows Phones need updating and Prime subscribers are streaming:

Facebook and several banks have been slapped with a lawsuit, accused of hiding some details about revenue estimates days before the stock went public. The charge is this: Facebook spoke with select analysts about additional information on revenue expectations than what was disclosed in amended filings. Smaller investors are upset they were left out of the loop, and say they lost money because they didn't know the full picture. But even if Facebook did give extra info to analysts, it's not … Read more

How Nvidia can accelerate the graphics in your apps

If you want to create some pretty apps, look to Nvidia.

The company, best known for its graphics processors in PCs and laptops, has during the past year branched out into the mobile world with its ARM-based Tegra processor, specifically designed for mobile devices such as phones and tablets. The company has quickly gone from an outsider to a niche player, serving high-end devices.

Its Tegra 3 quad-core processor is found in a handful of top-tier products, including the Asus Transformer Prime, the first tablet with Google's Ice Cream Sandwich variant, as well as international versions of HTC's … Read more

Which Transformer tablet is right for you?

Yesterday Asus launched its third tablet in a year with the name "Transformer" in it: the Asus Transformer Pad TF300. In April 2011, the Transformer TF101 was released and was followed by the much more powerful Transformer Prime TF201 last December.

With three tablets with the Transformer name out there in the wild, this is a great opportunity to illustrate their differences in a concise manner. Tables help with that, but if you're not a table person and prefer wordy prose, I've got that too.

According to Asus, the new $380 (for 16GB) Transformer Pad TF300 now replaces the TF101 as Asus' "low-end" full-size tablet. The TF101 will officially be available through the second quarter of 2012, and Asus claims it will continue to offer software updates and tech support.… Read more

Asus Transformer Pad TF300 review: A cheaper Prime?

The Asus Transformer Prime was the great silver hope for Android fans -- and by "silver" I mean "champagne gold" or "amethyst gray" or whatever awkward-sounding color combo Asus assigns to its tablet.

Arguably, the Prime marked the first time Android fans could hold up a tablet to their iPad-owning frenemies and say, "Now I own the most powerful -- on paper at least -- tablet in the universe!" Or something like that.

Aside from some GPS and Wi-Fi issues, the Prime was a robust and powerful tablet, but was probably too expensive for most wallets. Enter: the Transformer Pad TF300.… Read more

Did the Asus Transformer Pad just pop up early on Amazon?

Last week the Asus Transformer Pad 300 -- the follow-up to the acclaimed Transformer Prime tablet that drops the "Eee" branding, as well as about $100 from the price -- started popping up on some retailers' sites for preorder, with an anticipated available date of April 22.

Now, as of this morning, the Transformer TF300 is listed as "In Stock" on Amazon, with three different merchants -- including Amazon itself -- saying they'd be happy to sell you one.

Of course, if you're thinking you can order one with your Amazon Prime account and … Read more
