If you do, you will sooner or later need to deal with spam. This article is about how to waste spammers' time and have a good time while doing it, using the free tools OpenBSD offers to do your greylisting and greytrapping before any content filtering. It's fun and easy."

4-Billion-Pixel Panorama View From Curiosity Rover 101

Posted by samzenpus
from the take-a-look dept.
SternisheFan points out that there is a great new panorama made from shots from the Curiosity Rover. "Sweep your gaze around Gale Crater on Mars, where NASA's Curiosity rover is currently exploring, with this 4-billion-pixel panorama stitched together from 295 images. ...The entire image stretches 90,000 by 45,000 pixels and uses pictures taken by the rover's two MastCams. The best way to enjoy it is to go into fullscreen mode and slowly soak up the scenery — from the distant high edges of the crater to the enormous and looming Mount Sharp, the rover's eventual destination."

Earliest "Writing" On 60,000-Year-Old Eggshells 214

Posted by kdawson
from the beats-walking-on-them dept.
New Scientist reports on research published in PNAS (abstract here) about what may be the earliest writing yet discovered, on eggshells dated to 60,000 years ago. "Since 1999, Pierre-Jean Texier of the University of Bordeaux, France, and his colleagues have uncovered 270 fragments of shell at the Diepkloof Rock Shelter in the Western Cape, South Africa. They show the same symbols are used over and over again, and the team say there are signs that the symbols evolved over 5,000 years. This long-term repetition is a hallmark of symbolic communication and a sign of modern human thinking, say the team. [Another researcher is quoted:] 'Judging from what we know about the evolution of art all over the world, there may have been many [written language] traditions that were born, lasted for some time, and then vanished. This may be one of them, most probably not the first and certainly not the last.'"

Comment: Stroustrup chose proportional-width (Score 4, Interesting) 394

by Looke (#30797874) Attached to: Programming With Proportional Fonts?

All code in Stroustrup's "The C++ Programming Language" is presented in a proportional-width font: "At first glance, this presentation style will seem 'unnatural' to programmers accustomed to seeing code in constant-width fonts. However, proportional-width fonts are generally regarded as better than constant-width fonts for presentation of text. Using a proportional-width font also allows me to present code with fewer illogical line breaks. Furthermore, my experiments show that most people find the new style more readable after a short while."

Not only is the font proportional, but it's bold, italic, and serif as well. Now, reading a textbook is of course pretty different from editing on-screen, but I remember reconsidering some of my habits after reading that book. That code ain't hard to read.

CMU Web-Scraping Learns English, One Word At a Time 148

blee37 writes "Researchers at Carnegie Mellon have developed a web-scraping AI program that never dies. It runs continuously, extracting information from the web and using that information to learn more about the English language. The idea is for a never ending learner like this to one day be able to become conversant in the English language." It's not that the program couldn't stop running; the idea is that there's no fixed end-point. Rather, its progress in categorizing complex word relationships is the object of the research.

My dirt-cheap Brother DCP-130C came with full cartridges. I guess that's because the fixed costs of producing two lines of ink for the same printers are too high. HP, Epson and Canon sell a lot more printers and ink.

The downside to this printer is that it refuses to print anything, even plain b/w, once one colour cartridge is empty. I fooled it with a piece of black tape.

"Scrolling the text sideways"? It doesn't sound like you ever tried a decent mobile browser, like Opera Mini. It reflows text and resizes images to fit your little 3 inch window. For a whole lot of sites out there, neat and simple tricks like that work brilliantly.

As for the rise of web apps that the article brings up, that's where a mobile browser like Opera Mini falls short.

It could be be an advantage for the colour blind, too. If text is tagged "important" instead of "red" or "bold", then it can render blue for koreans and bold for colour blinds. This means you cannot blame it on software anymore; you should have clicked the "important" button, not what you thought was "red".

DHS To Use Body Odor As a Lie Detector 206

Posted by samzenpus
from the we-can-smell-the-truth dept.
The US Department of Homeland Security is studying lies, damned lies, and smells. They hope to prove that human body odor could be used to tell when people are lying. The department says they are already "conducting experiments in deceptive behavior and collecting human odor samples" and that the research it hopes to fund "will consist primarily of the analysis and study of the human odor samples collected to determine if a deception indicator can be found."

Wolfram Promises Computing That Answers Questions 369

Posted by timothy
from the he's-feeling-lucky-you-feel-lucky-too dept.
An anonymous reader writes "Computer scientist Stephen Wolfram feels that he has put together at least the initial version of a computer that actually answers factual questions, a la Star Trek's ship computers. His version will be found on their Web-based application, Wolfram Alpha. What does this mean? Well, instead of returning links to pages that may (or may not) contain the answer to your questions, Wolfram will respond with the actual answer. Just imagine typing in 'How many bones are in the human body?' and getting the answer." Right now, though the search entry field is in place, Alpha is not yet generally available -- only "to a few select individuals."
