There a many corporate-sponsored contests like this photography, mostly geared at amateurs. Back in the 80s I learned to look at the terms carefully, and if anywhere in them was a clause giving up rights to the photographs entered to the contest-holder, to run far away. Prestigious contests always make it clear that all rights remain with the photographer, although they may legitimately request a time-limited right to display entries for promotional purposes only, not for resale ever.

Stock agencies used to use these contests to pick up vast swaths of decent, if unremarkable, photographs for almost nothing, and with no pesky trouble like having to keep track of who took the photo for credit and payment. I imagine now with Flickr and the flood of digital images, they don't really have work even that hard.

All this remains true for programming contests, and really any contest where the creative work of an individual is made available to another party.

Gasoline From Thin Air 283

disco_tracy writes "An enzyme found in the roots of soybeans could be the key to cars that run on air. If perfected, the tech could lead to cars partially powered on their own fumes. Even further into the future, vehicles could draw fuel from the air itself. Quoting: 'The new enzyme can only make two and three carbon chains, not the longer strands that make up liquid gasoline. However, Ribbe thinks he can modify the enzyme so it could produce gasoline. ... [Perfecting this process] won't happen anytime soon... "It's very, very difficult," to extract the vanadium nitrogenase, said Ribbe.'

Where To Start With DIY Home Security? 825

secretrobotron writes "I'm a recent university graduate from a co-op system which has kept me on the move every other semester, so I've never really had a permanent place to live, and I've never had the opportunity (or the capital) to buy expensive things. Now that I'm working, those restrictions on my life are gone and I'm living in an apartment with things I don't want stolen. I would love to build a DIY home security system, but I don't even know where to start since Google searches reveal things like diysecurityforum.com, which help only to an extent for a curious newcomer. Has anybody out there successfully built a home security system on a budget? If so, where did you start?" Related query: When similar questions have come up before, many readers have recommended Linux-based Zoneminder (last updated more than a year ago); is that still the state of the art?

How Should a Non-Techie Learn Programming? 346

CurtMonash writes "Nontechnical people — for example marketers or small business owners — increasingly get the feeling they should know more about technology. And they're right. If you can throw up a small website or do some real number-crunching, chances are those skills will help you feed your family. But how should they get started? I started a thread with the question on DBMS2, and some consistent themes emerged, including: Learn HTML + CSS early on; Learn a bit of SQL, but you needn't make that your focus; Have your first real programming language be one of the modern ones, such as PHP or Python; MySQL is a good vehicle to learn SQL; It's a great idea to start with a project you actually want to accomplish, and that can be done by modifying a starter set of sample code (e.g., a WordPress blog); Microsoft's technology stack is an interesting alternative to some of the other technology ideas. A variety of books and websites were suggested, most notably MIT's Scratch. But, frankly, it would really help to get more suggestions for sites and books that help one get started with HTML/CSS, or with MySQL, or with PHP. And so, techie studs and studdettes, I ask you — how should a non-techie go about learning some basic technological skills?"

Too Much Multiplayer In Today's Games? 362

hornedrat writes "Gamepro discusses the idea that modern games put too much emphasis on multiplayer, and that players aren't as concerned about it as developers think. 'The current environment encourages developers to unnecessarily toss multiplayer into their games without caring about it — or even considering whether anyone will bother playing it. It’s like they're checking an invisible quota box that demands multiplayer's inclusion.' Personally I agree that too much emphasis is placed on competitive multiplayer. I play online, but only with my brother in games that allow co-operative modes, like Rainbow Six: Vegas and ARMA 2. 'My point isn't that developers shouldn't try and conquer Halo or Call of Duty. We'd never have any progress in this industry if developers didn't compete. Game companies, however, should think carefully about what they want their games to be, and more important, gamers should consider what they want. If a developer wants to eclipse Halo, then by all means, pour that effort into a multiplayer mode that's different.' I would be interested to know how many gamers really care about the multiplayer components of the games they buy."

The Possibility of Paradox-Free Time Travel 421

relliker writes in with word of a paper up on the ArXiv by Seth Lloyd and co-workers, exploring the possibility that "postselection" effects in non-linear quantum mechanics might allow paradox-free time travel. "Lloyd's time machine gets around [the grandfather paradox] because of the probabilistic nature of quantum mechanics: anything that this time machine allows can also happen with finite probability anyway... Another interesting feature of this machine is that it does not require any of the distortions of spacetime that traditional time machines rely on. In these, the fabric of spacetime has to be ruthlessly twisted in a way that allows the time travel to occur. ... Postselection can only occur if quantum mechanics is nonlinear, something that seems possible in theory but has never been observed in practice. All the evidence so far is that quantum mechanics is linear. In fact some theorists propose that the seemingly impossible things that postselection allows is a kind of proof that quantum mechanics must be linear."

Comment Why profitable? (Score 5, Insightful) 299

The article starts from a false assumption: that the postal service must be profitable, or at least break even.

Framing the issue this way has nothing to do with what the USPS should or should not carry, or how much they should charge.

Why is that so for the postal service but not for the military, department of transportation, or most any other government agency that provides a service? Universal free mail delivery is something that the citizens of the US want -- or at least did at one time. As a government service, it's something taxpayers agree to pay for.

Now clearly the two authors of this article, management consultants, have a different view of that need. Perhaps they are ideologically inclined to expect that government services should break even or better, in which case, they ought to take on a real challenge and explain to the Pentagon how they can "save" the armed forces. Or perhaps they have a financial interest in private delivery services like FedEX and UPS, who knows? It's clear from early in the article, "Should the federal government continue to compete against the private sector?" that the authors have a sense that somehow there's money to made for UPS, FedEx, and other private delivery services if the postal service was forced to compete on the same level as them. I'm sure they wouldn't advocate for reforming USPS if they thought it would take money away from the private sector.

In any case, before people go trying to reform USPS, let's first decide if we want to continue to support the current expectation of free (for the recipient) door-to-door mail service for everyone in the country everywhere. If citizens clearly want that, then budget (and tax) for it, and shut up about billion dollar "losses" that pale compared to the "losses" racked up by other services we expect as a modern nation. On the other hand, if the country decides that hey, we don't need to deliver everywhere any more, then go ahead, revamp the postal service to be just another profit-motivated competitor.

Comment Re:The Big B finally weighs in. (Score 5, Insightful) 114

If I were SpaceX founder Elon Musk, I'd be hopping mad right now. After developing Falcon9 and Dragon on the basis of a truly competitive commercial space program, the porkbarrel senators for aerospace/defense contractor states wrote a new NASA budget to basically hand money over to Boeing and the rest of the usual cast of trough-feeders to continue but with changes and more delays the Ares/Orion program. This craft will see about as much reality as the Orion did before Boeing is behind schedule and over budget and requests yet more money.

The whole goal is to crowd out the smaller guys while maintaining the jobs programs in states like Washington, Utah, and Florida.

Did anyone notice that they don't say where they are going in this capsule? Where are the senators who called Obama's proposed budget a mission to nowhere? This new NASA program doesn't have a destination, either, but at least the dollars keep flowing to the same interests.

Student Wants Science To Name 'Hella' Big Number Screenshot-sm 193

thodelu writes "Austin Sendek, a 20-year-old UC Davis student, is trying to get scientists from Boise to Beijing to use the term 'hella' to denote the unimaginably huge, seldom-cited quantity of 10 to the 27th power. From the article: 'It started as a joke, but Sendek's Facebook petition: to the Consultative Committee on Units, a subdivision of the Bureau International des Poids et Mesures, has drawn more than 60,000 supporters. Its chances for formal adoption by the global weights-and-measures community are hella dim, but Google was so taken with Sendek's modest proposal that it incorporated "hella" in its online calculator.'"

I haven't looked at the guts of any of Apple's NS* classes, but I don't doubt there's some places where it's a mess -- it's ancient code, those, where the Android code is new. But just because the feature is part of the SpringBoard application doesn't mean it's badly coded. What classes in the NS SDK specifically?

You're right about one thing: You've reminded once again that I made the right choice in quitting the industry after holding a variety of lucrative sysadmin, software development, IT, and technical lead positions from 1983 to 2009. Too many projects where getting it done mattered more than getting it right, ending up in the software equivalent of a Deepwater Horizon rig explosion. I'm so glad to be done with that.
