The holiday cheer soured this week when a reader of a United Kingdom-based technology news site, The Register, reported that a chat between Santa and his underage nieces about eating pizza prompted Santa to bring up oral sex.

One of the publication's writers replicated the chat Monday. After declining the writer's repeated invitations to eat pizza, a frustrated Santa burst out with, "You want me to eat what?!? It's fun to talk about oral sex, but I want to chat about something else."

The exchange ended with the writer and Santa calling each other "dirty bastard."

Microsoft spokesman Adam Sohn said the company's engineers tried to clean up Santa's vocabulary, but even after making changes to the software, the company wasn't comfortable keeping him online.

You can try it for yourself in Excel by multiplying 850 by 77.1. Excel will return 100,000 instead of 65,535. Similar operations that should return 65,535 will also come back incorrect, and there's a problem with 65,536, too. The problem is only present in Excel 2007; earlier versions of Excel are not affected.

Microsoft has traced the problem back to a floating point issue and how results are displayed within a cell in Excel. Microsoft says the calculation is actually done correctly, it's just that when it comes time to show the result on screen, Excel chokes. For example, if you multiply that "100,000" above by 2 and put the answer in a new cell, you'll get 131,070, not 200,000. However, this isn't reliable either: Try adding one and you get 100,001, not 65,536.

So what, specifically, are the values that cause this display problem? Of the 9.214*10^18 different floating point numbers (floating point on wikipedia) that Excel 2007 can store, there are 6 floating point numbers (using binary representation) between 65534.99999999995 and 65535, and 6 between 65535.99999999995 and 65536 that cause this problem. You can't actually enter these numbers into Excel directly (since Excel will round to 15 digits on entry), but any calculation returning one of those results will display this issue if the results of the calculation are displayed in a cell. All other calculation results are not affected.

An explosive device blew out a thick, plate-glass window Tuesday evening at the Silicon Valley headquarters of PayPal, the online payments unit of eBay.

No injuries resulted when what local fire officials said was an explosive device shattered a 6-foot-square window on the ground floor of the four-story building in San Jose. The explosion occurred outside a building exit.

Investigators were still trying to determine the nature of the device. "Whatever it was, it disintegrated," San Jose Fire Department Capt. Jose Guerrero said. "Whatever caused this was pretty strong."

About 45 employees were working in the PayPal offices when the explosion occurred at 7:24 p.m., eBay spokesman Hani Durzy said. Most employees had left the building early ahead of the Halloween holiday celebrations, he said.

The company will require that all of its cafes and cafeterias serve only the pricier cage-free eggs, the San Jose Mercury News reports. Google uses about 300,000 eggs a year along with 7,000 pounds of liquid egg products.

Animal-rights activists charge that caged chickens -- sometimes called battery-raised, because the cages are piled high -- have miserable lives during their productive egg-laying months, confined six to a cage with only 67 square inches of floor space per chicken. Egg farmers say caged chickens are just as happy as -- and healthier than -- those raised outdoors or in open barns.

Google is jumping on a bandwagon that already includes America On Line and Bon Appetit Management, a catering company serving a number of Silicon Valley companies. Several universities have also pledged to serve cage-free eggs.

First Clocky, now this. Aaron Tang’s Anemone Clock rumbles when the alarm goes off, eventually shaking its way all across your room, forcing you to get up to stop it. But that’s not all — it keeps shaking when you pick it up, making it a frustrating exercise just to find the off button. Tang didn’t say if the clock had a snooze button so you can repeat this process a few times each morning.
