snydeq writes "Canonical is preparing a version of the Ubuntu OS for tablet computers as the company looks to extend its presence in the mobile space, InfoWorld reports. The OS will be a lightweight version of Linux with a simplified, touch-friendly user interface, and tablets with the Ubuntu OS could become available late in winter 2011. The focus will be on developing an OS with a simplified user interface that provides quick access to the most-used applications. Development efforts will also focus on adding on-screen keyboard features and compatibility for multitouch drivers."

2 In 3 Misunderstand Gas Mileage; Here's Why 1042

Posted by kdawson
from the bad-at-math dept.
thecarchik sends in this piece, which was published last March but remains timely: "OK, so here's a little test: Which saves more gasoline, going from 10 to 20 mpg, or going from 33 to 50 mpg? If you're like most Americans, you picked the second one. But, in fact, that's exactly backwards. Over any given mileage, replacing a 10-mpg vehicle with one that gets 20 mpg saves five times the gasoline that replacing a 33-mpg vehicle with one that gets 50 does. Last summer, Duke University's Fuqua School of Business released a study that shows how much damage comes from using MPG instead of consumption to measure how green a car is. Management professors Richard Larick and Jack Soll's experiments proved that consumers thought fuel consumption was cut at an even rate as mileage increased."

US Confirms Underwater Oil Plume 353

from the told-you-so dept.
oxide7 writes "An underwater three-dimensional map of the oil spill is closer to becoming a reality, now that the US has for the first time confirmed the discovery of a subsurface oil plume resulting from the ruptured BP well. The government agency in charge of ocean science has received the first of several expected reports from university investigators aboard research ships detailing specific locations where oil has been found below the surface of the Gulf of Mexico. The government, which denied reports of giant underwater oil plumes in mid-May, said researchers at the time had not confirmed the presence of conglomerated oil." The New York Times talked with scientists on a two-week mission in the Gulf and reported them "awed" at the size and density of the underwater plume.

Wake Forest Researchers Swap Skin Grafts For Cell Spraying 123

TigerWolf2 writes with this excerpt from a Reuters story carried by Yahoo: "Inspired by a standard office inkjet printer, US researchers have rigged up a device that can spray skin cells directly onto burn victims, quickly protecting and healing their wounds as an alternative to skin grafts. ... Tests on mice showed the spray system, called bioprinting, could heal wounds quickly and safely, the researchers reported at the Translational Regenerative Medicine Forum."

Robotics Prof Fears Rise of Military Robots 258

from the oh-you-worry-too-much dept.
An anonymous reader writes "Interesting video interview on with Sheffield University's Noel Sharkey, professor of AI & robotics. The white-haired prof talks state-of-the-robot-nation — discussing the most impressive robots currently clanking about on two-legs (hello Asimo) and who's doing the most interesting things in UK robotics research (something involving crickets apparently). He also voices concerns about military use of robots — suggesting it won't be long before armies are sending out fully autonomous killing machines."

IE 0-Day Flaw Used In Chinese Attack 318

bheer writes "A zero-day attack on IE was used to carry out the cyber attack on Google and others that's been getting so much ink recently, reports The Register, quoting McAfee's CTO. While the web (and security) community has pointed out the problems with IE's many security flaws (and its sluggish update cycle) in the past, IE shows no sign of vanishing from the corporate landscape."

Google Switching To EXT4 Filesystem 348

from the make-money-with-open-source dept.
An anonymous reader writes "Google is in the process of upgrading their existing EXT2 filesystem to the new and improved EXT4 filesystem. Google has benchmarked three different filesystems — XFS, EXT4 and JFS. In their benchmarking, EXT4 and XFS performed equally well. However, in view of the easier upgrade path from EXT2 to EXT4, Google has decided to go ahead with EXT4."

This from their FAQ - Technical Topics (

Q. How can I block Tynt Insight from monitoring my actions?

A. Tynt understands that some people are uncomfortable having events from their web browsing recorded in a database. We take your privacy concerns seriously and we are therefore investing considerable effort into developing a feature that will allow users to block Tynt software across all the sites that are using it, from within their own browser. Until we have this blocking feature ready, it is possible to achieve a similar effect by using one of the many ad blocking components available on the net. For Firefox users, we have found Adblock plus to work well, and Super Ad Blocker is effective for IE users.

I can't wait to download and install software they've written to help me block them from tracking me with their software. Good thing I'm using Ad Block Plus and NoScript while I wait, or they'd know I cut-n-pasted that...

Comment: sat terminals (Score 2, Informative) 139

40 sat terminals are being established, along with 60 broadband terminals, from the ITU. A lot of stuff has to be moved in, because so much was destroyed

I was looking at various pics of the destruction, and it is trite and often used, but it looks like a major giant airforce just carpet bombed the place.

I have never been there, but based on other articles I have read about real poor areas with cellphones, a lot of the people depend on charging kiosks / local services to recharge their phones, because domestic electricity is so rare. I would imagine most of those facilities are now smashed as well.

by Lord Lode (#30768084) Attached to: Does Your PC Really Need a SysRq Button Anymore?

Print screen isn't that rarely used. Maybe if you'd remove that ability you'd find out you miss it more than you think. And print screen button is the standard in Windows, Gnome and KDE. There is no other sane known keyboard shortcut for this. If the print screen button is gone, No desktop or Windows will properly support print screen anymore, I don't think they'll bother finding another combination for it. And using various "screen grab" tools is too much work.


Best Way To Put a Monitor On a Robot? 48

I'm part of my schools IGVC team, and we're upgrading our bot's computer to an onboard mini-itx. Most of the access to the box is gonna be through ssh, but I want a terminal I can just mount on the bot for convenience. Bidding on a psOne LCD already, but what are some good options if that doesn't pan out? I want to keep it as cheap as possible and small (in the 5-7 inch range). I haven't found any good guides to modding a digital photo frame or portable DVD player, but I'm probably just not looking in the right places.
