Comment I've followed these studies forever... (Score 3, Informative) 258

Just a few years ago, a Canadian study using baseball stats (because they tracked handiness closely) concluded that lefties were far more likely to die, ( http://www.nejm.org/doi/full/10.1056/NEJM199110033251412) this was later shown to have suffered a seemingly paradoxical sampling error (not controlling adequately for those that didn't die). Then there was another study that concluded that left-handedness was likely the result of anoxia in the womb ( http://www.sciencedirect.com/science/article/pii/002839327390050X). It was discounted for similar sampling error problems. Neurological "wiring error"; perhaps a mutation with few consequences; advantages in the mathematical world (presumably via having a screwy mindset); Language disadvantages; Language *advantages*; high proportion of left-handed (possibly suppressed) American presidents http://www.anythingleft-handed.co.uk/presidents.html (Clinton, Bush, Obama ... ). So... run a elaborate predator/prey model applied to sports and see an advantage for the 10% that are different; sounds like rediscovery of Perato distribution to me, http://en.wikipedia.org/wiki/Pareto_distribution I'm just not convinced that there's been a proper scientific approach to this issue to date, and until then i'm still stuck with a twisted spine in most college classrooms.

Canadian Mint To Create Digital Currency 298

Oldcynic writes "The Canadian mint has allowed 500 developers to enter a contest to create a new digital currency. The currency would allow micro payments using electronic devices. From the article: 'Less than a week after the government announced the penny’s impending death, the Mint quietly unveiled its digital currency called MintChip. Still in the research and development phase, MintChip will ultimately let people pay each other directly using smartphones, USB sticks, computers, tablets and clouds. The digital currency will be anonymous and good for small transactions — just like cash, the Mint says. To make sure its technology meets the gold standard in a world where digital transactions are gaining steam, the Mint is holding a contest for software developers to create applications using the MintChip.'" It looks like the Canadian Mint might have a bit of Sweden envy.

Ask Slashdot: A Cheap, DIY Home Security and Surveillance System? 508

scubamage writes "Six weeks ago, my home was broken into while my fiance and I were at work. Two laptops were stolen, an iPad, a power brick, a safe (complete with several years worth of taxes, my birth certificate, and old copies of my driver's license), a digital SLR, and several other costly items. We are now dealing with an attorney because the homeowner's insurance is fighting us on a number of items and we're not backing down. It has been a nightmare. However, we've now noticed that someone has been visiting our house during the day. There has been garbage left sitting on our back porch table, so its unlikely to have blown there. We've also seen footprints in our garden that are not there in the morning. Our neighborhood is essentially empty during the day, and we want to know who is on our property while we're not. If we're really lucky, reporting it to the police could recover some of our property. My fiance has asked me to assemble a home security system that is motion activated, and both notifies us of an entry, as well as records video or rapid HD stillframes when sensing motion. The goal is to do this cheaply and more effectively than going with a private security company like ADT (who, consequently, our police department told us to ignore due to the incredibly high rate of false alarms). We've already gotten the dog and the gun, so we have those bases covered. What suggestions do you have on setting up home security systems, and what have you done to build one in the past?"

Yes, this is exactly my point too. As an limiting argument, let's say my window manager had some-sort of graphics interface with more bells and whistles than emacs. "ooo look! i wrote a script that resulted in a full Donkeykong game in less than 32 characters!!" of course, that was one of the features of the fancy fictitious graphics interface that there are a number of example games that could be started with the equivalent of "run('donkkong')"

Why Linux Can't 'Sell' On the Desktop 1091

New submitter VoyagerRadio writes "Recently I found myself struggling with a question I should easily have been able to answer: Why would anyone want to use Linux as their everyday desktop (or laptop) operating system? It's a fair question, and asked often of Linux, but I'm finding it to be a question I can no longer answer with the conviction necessary to 'sell' the platform. In fact, I kind of feel like a car salesman who realizes he no longer believes in the product he's been pitching. It's not that I don't find Linux worthy; I simply don't understand how it's ever going to succeed on the desktop with voluntary marketing efforts. What do Linux users need to do to replicate the marketing efforts of Apple and Microsoft and other corporate operating system vendors? To me, it seems you don't sell Linux at all because there isn't supposed to be one dominant distribution that stands out from the rest. Without a specific product to put on the shelf to sell, what in the world do you focus your efforts on selling? An idea?"

Comment 3d, a solution desparately in search of a problem (Score 2) 70

The central problem with 3d-ing stuff is that it solves no problem, scratches no apparent itch, feeds no bull-dog, *and* annoys the pig. Every implementation i've been 'lucky' enough to observe comes off as a skit John Candy did where the 3d feature was made the central feature of the plot (of some silly B-movie). oh, here's a sample (forgot it was "Dr Tongue") http://www.youtube.com/watch?v=4u4tTFEF_XE

Booktype: An Open Source, Cross-Platform Approach To E-Book Publishing 87

Despite Apple's protestation that the iBooks Author EULA was misinterpreted, the idea of a book publishing system that could be used to grab copyright of the prepared text is annoying — like the sort of EULAs that seem to give photo-sharing sites unlimited re-use rights of hosted personal photos. New submitter rohangarg points out a publishing system which shouldn't have such problems, and is nicely cross-platform besides: "A new open-source digital writing and publishing platform has been launched by non-profit group Sourcefabric. Booktype allows for collaborative editing and writing of books that can be easily outputted to on-demand print services and eReaders such as the Amazon Kindle, Nook, iPad, and more with a few simple clicks. Booktype source can be found here." The online demo also leads to some downloadable examples (as PDFs).

Comment Tricky bit here is when there's software involved (Score 1) 64

These efforts are to a large extent laudable, and ought to be encouraged in any case; ...however, it gets messy when this hardware requires firm/soft -ware which comes only on a proprietary platform, or binary only libraries, or libraries which require binary only libraries. .Net, Eagle, MPLAB... are easy examples, others are more subtle. These guys know about this problem and either are "working" on it (and for that, gawdbless'em), or in some few cases, just don't give a damn; (there is a buck to be made presenting it thus after-all). So, "Open Source Hardware" is often "Open Hardware", sans the source.
