Posted by samzenpus on Thursday July 01, 2010 @01:39AM from the hospital-pill dept.

Whether you are a doctor diagnosing patients in the rural areas of Africa or a Homeland Security agent working to thwart an act of bioterrorism, one of these little devices should be your sidekick."

Attractive Open Source Search Interfaces? 65

Posted by timothy on Wednesday January 13, 2010 @04:22PM from the you'll-have-this-ansi-terminal-and-like-it dept.

An anonymous reader writes "I work for a company that manages an online database for the political market. We add to this DB daily with updates from a variety of sources and our customers then search through this content via our Solr/Lucene search engine. My problem is, our search interface is a little, well, basic and I would love to know if there are any feature-rich open source alternatives out there. The only one I can find is Flamenco, and while that seems strong on categorisation, that seems to be about the height of it."

Apple Quietly Releases Safari 3.2 129

Posted by kdawson on Sunday November 16, 2008 @09:15AM from the new-shinies dept.

99BottlesOfBeerInMyF writes "Yesterday Apple quietly slipped out an update to their Safari Web browser to version 3.2. The notable feature is that it finally adds anti-phishing technology, an area where Safari has lagged behind competitors. Aside from that, it provides some security fixes, improved JavaScript performance, and a slightly newer version of Webkit, pulling their Acid3 score up to 77." Apple forums across the Net are reporting frequent crashes in Safari 3.2, some possibly caused by 3rd-party add-ons, others perhaps related to the anti-phishing feature.

Or the incomparable smog Milanesi put up with? PopSci has culled an eye-opening selection of some of the world's most problematic cities. From the painfully high cancer rates in Sumgayit, Azerbaijan to the acid rain destroying La Oroya, Peru, writer Jason Daley walks readers through the lowest of the low; and explains why, despite it all, there's still hope for these places."

The World's Nine Largest Science Projects 89

JBG667 writes "Nice overview of the 9 largest science projects currently ongoing. Some of the usual suspects are on the list including CERN, Space Elevator, Space Station, etc. As well as some lesser known including a 3,000-foot-tall 'Solar tower,' the ANTARES underwater neutrino detecting array, and more. Nice read for science buffs."

Internet Devices Get Their Own Ubuntu Version 87

Posted by samzenpus on Wednesday June 25, 2008 @08:08PM from the your-own-personal-linux dept.

Barence writes "A version of Ubuntu targeted specifically towards mobile internet devices (MIDs) has been released by Canonical, although there is presently only one product on the market which can use it. According to the company, the pithily titled Mobile Internet Device Edition 8.04 has been optimized for use with handheld internet platforms, and designed to run smoothly on Intel's Atom chips as well as with small touchscreen displays. This follows Canonical's announcement earlier this month that it would be creating a version of Ubuntu for netbook devices such as the Asus Eee PC and the Acer Aspire One called Netbook Remix."

Liberation Fonts Increase Interoperability For Linux Users 99

Posted by timothy on Wednesday June 25, 2008 @05:36PM from the yes-yes-gnu-slash-linux dept.

hweimer writes "Most problems when opening Word documents under GNU/Linux are due to missing fonts. Therefore, Red Hat published a set of fonts metric-compatible with the Windows core fonts last year. However, there were some concerns regarding the licensing that prevented many other distros to ship them. We finally managed to settle these problems, leading to better document interoperability for all GNU/Linux users."

Google Begat the End of the Scientific Method? 387

Posted by CmdrTaco on Wednesday June 25, 2008 @11:42AM from the well-i-begat-a-roast-beef-sandwich dept.

TheSauce writes "In a fairly concise one-pager from Chris Anderson, at Wired, the editor posits that all of our current (or now previous) models for collecting data are dead. The content is compelling. It notes that we've entered the Age of the Petabyte — where one can collect immense amounts of data that are paradigm agnostic. It goes on to add a comment from the head of Google's R&D, that we need an update to George Box's maxim: 'All models are wrong, and increasingly you can succeed without them.' Have we reached a time where all of our tool-sets are now made moot by vast clouds of information and strictly applied maths?"

Except...The US absorbs more CO2 than it puts out (see previous /. post) Until recently, India produced more CO2 than the US - slash-and-burn agriculture - And Indonesia and many other countries - are contributing a lot of CO2 the same way. More telling are the high level noctilucent clouds coming down from Canada earlier, and staying longer. High level clouds let sunlight in and reflect heat back. Methane (a much worse greenhouse gas than CO2) contributes to noctilucent clouds - cosmic rays convert much of it to water vapor. One source of methane usually not mentioned in the press is methyl hydrate found on continental shelves. Two major eruptions of methane occured off the north coast of Norware at the end of the last ice age. Three major eruptions are reported as having occured 100,000 years ago - with a substantial increase in earths temperatire.
