Engineering Election Debates With Subtle Cues 105

smolloy writes "A recent innovation in televised election debates is a continuous response measure (the 'worm') that allows viewers to track the response of a sample of undecided voters in real-time. A potential danger of presenting such data is that it may prevent people from making independent evaluations. Researchers from Royal Holloway, University of London, and the University of Bristol, report an experiment with 150 participants in which they manipulated the worm and superimposed it on a live broadcast of a UK election debate. The majority of viewers were unaware that the worm had been manipulated, and yet the researchers were able to influence their perception of who won the debate, their choice of preferred prime minister, and their voting intentions."

Cylindrical Rolltop Laptops 159

akshaynhegde writes "Germany's Orkin Design has proposed this fantastic concept of a futuristic laptop. The rolltop is a 'rolled up' laptop. By using the flexible OLED and touchscreen technologies, the created concept is a cylindrical laptop which can be rolled out when it needs to be used and can be rolled up again when not used." Something tells me it will be a little while before you will be unrolling your laptop on a plane.

To be fair, it does make a lot of sense to do something like that if you're going to be getting a large number of small dollar amount donations. There are costs associated with processing a donation and it's a lot cheaper for the charity to process a single $2M donation than 1M $2 donations. A retailer collecting that along with a purchase will have most of those costs to make the sale anyway. Doing it this way also provides a way to do that charitable donation as something like an impulse purchase, probably resulting in a lot of people donating who might not have considered doing it otherwise.

Now, I'd also say no because I'm not a huge fan of * awareness charities and the dirty look is bad service, but I fail to see the problem with the rest of it.

TSA To Retest Full Body Scanners For Radiation 199

cultiv8 writes with this excerpt from USA Today: "The Transportation Security Administration announced Friday that it would retest every full-body X-ray scanner that emits ionizing radiation — 247 machines at 38 airports — after maintenance records on some of the devices showed radiation levels 10 times higher than expected. The TSA says that the records reflect math mistakes and that all the machines are safe. Indeed, even the highest readings listed on some of the records — the numbers that the TSA says were mistakes — appear to be many times less than what the agency says a person absorbs through one day of natural background radiation. Even so, the TSA has ordered the new tests out of 'an abundance of caution to reassure the public,' spokesman Nicholas Kimball says. The tests will be finished by the end of the month, and the results will be released 'as they are completed,' the agency said on its website."

DHS Eyes Covert Body Scans 386

CWmike writes "Documents obtained by the Electronic Privacy Information Center (EPIC) suggest that the US Department of Homeland Security has signed contracts for the development of mobile and static systems that can be used scan pedestrians and people at rail and bus stations and special event venues — apparently at times without their knowledge. Under consideration: An Intelligent Pedestrian Surveillance platform; an X-Ray Backscatter system that could detect concealed metallic and high-density plastic objects on people from up to 10 meters away; a walk-through x-ray screening system that could be deployed at entrances to special events or other points of interest, which could be installed in corridors and likely scan people walking through it without them knowing it, EPIC said."

How Cyborg Tech Could Link the Minds of the World 219

An anonymous reader writes "Science writer Michael Chorost has written a book that suggests that mankind may one day be able to link individual minds to share thoughts, feelings and perceptions by genetically modifying individuals brains and implanting computers based on neural networks in the body. Here he talks about the implications for human relationships, our sense of self and phenomenon like telempathy and dream brainstorming that this so-called World Wide Mind would make possible."

New Internal Cavity X-ray Technology for Airports Screenshot-sm 308

Thanks to a new type of X-ray scanner unveiled in Australia, annoyed TSA agents won't have to send you to a hospital for a body cavity scan, they can do it in-house. Officials say that more than 4,600 man-hours were wasted last year in hospitals waiting for scans. From the article: "Home Affairs Minister Brendan O'Connor said the scanners would also help innocent travelers. 'The option of an internal body scan will more quickly exonerate the innocent and ensure a minimum of delay for legitimate travelers,' Mr O'Connor said."

Journal Journal: Qt Ambassador Care Package

A while back I got an email from Nokia letting me know about the Qt Ambassador program. So, I sent them some information on a program that I wrote using Qt and someone there must have thought it was neat since they sent me a very nice gift.

Fox News Brings Video Game Violence Debate To a New Low 421

Fox News took another shot at the video game violence debate earlier this week when they asked whether Bulletstorm, an upcoming M-rated shooter from Epic Games, is the worst game in the world. The article links violent games with an increase in rapes, and suggests there should be greater penalties for selling to minors. Gaming website Rock, Paper, Shotgun breaks down the problems with the article's sensationalist claims and highlights the disingenuous cherry-picking of quotes. "Scott Steinberg, CEO of TechSavvy Global, and all-round industry guru, got in touch with me to show me the answers he submitted to Fox when they approached him for comment. The full answers are reproduced below, because what results is a fantastic interview on the subject of adult game content and regulation. Fox chose to use none of Steinberg’s comments in their final piece, opting instead for the more sensational claims of those with no expertise in the subject (neither of whom have found time to reply to our emails). But seeing these answers also provides further insight into how the mainstream media coverage of gaming stories works. Far from being a reporter ignorant of the subject and twisted by naive contributors, Fox correspondent John Brandon was equipped with a wealth of factual information and informed opinion before composing his frantic article."

Slashdot Launches Re-Design 2254

Today we are pleased to announce the launch of the third major re-design in our 13.5 year history, and I don't think it looks half bad. The new theme represents a serious gutting of the underlying HTML and CSS, as well as all-new graphics. There will be many design wiggles, bug squashes, and compatibility glitches that survived testing, so bear with us for a bit. Please direct your bug reports and feedback (good and bad!) to Garrett Woodworth who is currently in charge of such things. Thanks to him, Wes, Vlad, Dean, Phil and Tim, who have each worked hard to get this out the door. Juggling the needs of users, editors, and various business functions is a hard job, and you guys did good.

Comment Re:I Take Issue with the Phrase "Give Away" (Score 1) 450

The economic realities of the global coffee market are not as simple as you are making them out to be. Some historical perspective:

There was once a time when coffee was trading at high prices. Demand was increasing, supplies were not increasing as much, and there were countries capable of producing coffees that weren't. Getting people to plant coffee in these non-traditional producing areas was seen as a way to develop economies. This idea was not without precedent. Brazil was largely built on coffee money, after all. Now, it takes a few years from the time coffee is planted until it produces its first crop. Coffee isn't a crop where you plant it, harvest it a few months later, and know what you've got. It takes about 10 years before you really know what you have with coffee. All of the sudden you have a huge increase in global coffee production. Making the problem worse, these new coffee producers were exporting coffees of such poor quality that more established producers never allowed on the global market. Now, coffee does not really fit the definition of a commodity, but it was usually sold with contracts that specify a differential above or below the NYBOT C price with those differentials based on several factors such as the quality of the coffee (coffee better than exchange grade selling for more, worse coffee selling for less) and the producing country (a comparative advantage model doesn't really work because a specialty grade coffee from Panama isn't going to taste anything like a specialty grade coffee from Tanzania).

Up until this point, the NYBOT C was cyclical. Sometimes it would go bust, but it would recover. This time it was different. There had been a fundamental change in the market which kept prices depressed for a long period of time and the differentials weren't keeping up. Simply letting quality producers go out of business wasn't going to be good for the producers and it wasn't going to be good for buyers either because someone who wanted to buy a nice coffee from Mexico wasn't going to be interested in some garbage from Vietnam. By setting a floor price for some coffees, Fair Trade did a lot of good in keeping those producers in business. You might find it interesting to look into the details of some Fair Trade producers and see what they're doing with those premiums. In many cases they're using them to improve the quality of the coffee and diversify the local economy, both things which reduce long term reliance on the Fair Trade premium, which seems to be exactly what you're advocating (though you suggest doing that before getting the capital needed to undertake such projects).

Now we're back into a period of higher prices for coffee (NYBOT C is over 200 as I write this and the differentials aren't dropping quickly which is a big part of why many coffee firms either have or soon will be announcing price increases) and this is due to many factors. Looking at the fundamentals, this is cyclical and prices will drop again, but probably not substantially within the next 18 months. We also have a lot more diversity in price discovery mechanisms for coffee which is a positive development, particularly for producers of high quality coffees. Any Fair Trade cooperative ought to be looking into getting out of Fair Trade in the long term exactly because that's not a long term sustainable model. Some cooperatives have already made that jump, others will follow, but to argue that Fair Trade was not beneficial in the long term simply is not supported by fact.

I only need two keystrokes to get a division sign (option/) so I'm not really sure what you're going on about there. That said, I don't think it matters so much in terms of writing the code. As others have pointed out, we've been down that road with APL. Where this sort of idea really shines, however, is in reading the code. One of the comments on the article touched on this, so I'll quote the relevant bit:

Robert Melton | Mon, 01 Nov 2010 02:11:13 UTC
What an odd combination of criticisms... first and foremost, I think you already hit on the correct solution... custom syntax and creation mechanisms are best explored as layers on top of existing tools, not a fundamental part of a new tool. I believe to try to integrate your ideas would have crippled Go, and given it nearly no advantages, at the cost of a huge degree of developer mind share. Bootstrapping a language is hard enough without giving yourself new disadvantages. I have never seen Guido van Rossum claim anything other the "readability" and that it was the natural flow as foreseen by Knuth (1974)

The problem here, however, is a cultural one. I suspect that most of the people who write software have never read through a non-trivial program and come out of it with an understanding of the program (contrast this with novelists reading novels) and most software is written in such a way that reading the code for understanding is more like assembling a puzzle from diverse bits scattered all about.

We already have pretty much all of these presentation niceties with CWEB. I frequently write my programs in literate C++ and can use goofy characters with subscripts if I want. TeX markup in comments is very nice. Especially useful is having something a bit more visually distinctive separating assignment from equality testing, but the big gain here is that it makes it easier to write programs as code narratives which humans can read to gain an understanding of the program. Once you have someone reading the program, how the code is represented starts to matter. Granted, this is another example from the pile of ideas that never really caught on.
