bzip is better than gzip if space is at a premium. There are even multi-core versions of bzip2 that are very efficient. You could also look at p7zip. If you want a really efficient compressor, try nanozip as well, although its page says it is still experimental, but it seems to be at the top of several compression benchmarks.

Submission + - An open alternative to Kickstarter (techworld.com.au)

angry tapir writes: "Crowd-funding website Crowdtilt officially launched last week, expanding upon the collective fundraising model pioneered by Kickstarter to enable raising money for any project — even a beer blitz. Like Kickstarter, Crowdtilt allows users to create a fundraising campaign with a tipping point. If the effort falls short of the set amount, would-be donors are not charged. However, unlike Kickstarter, the platform allows users to "group fund anything." Users can initiate campaigns without first getting the approval of service administrators, which they must do on Kickstarter."

Submission + - Making a tablet run only one application. 2

An anonymous reader writes: I'm working for a medical centre who want to make a tablet with various videos and webpages about smoking cessation available in their waiting room. The tablet can't access the internet because of security policies. I'm planning to use a local server with copies of the (creative commons) videos and pages accessed through local webpages using the tablet's browser. How can I make only the browser be available to the tablet users? Ideas? Suggestions?

Submission + - Permafrost loss greater threat than deforestation? (bloomberg.com)

Pierre Bezukhov writes: Emissions from thawing permafrost may contribute more to global warming than deforestation this century, according to a commentary in the journal Nature.

Arctic warming of 7.5 degrees Celsius (13.5 degrees Fahrenheit) this century may unlock the equivalent of 380 billion tons of carbon dioxide as soils thaw, allowing carbon to escape as CO2 and methane, University of Florida and University of Alaska biologists wrote today in Nature. Two degrees of warming would release a third of that, they said.

The Arctic is an important harbinger of climate change because the United Nations calculates it’s warming at almost twice the average rate for the planet. The study adds to pressure on United Nations climate treaty negotiators from more than 190 countries attending two weeks of talks in Durban, South Africa that began Nov. 28.

Submission + - Stephen Wolfram Bets on Singularity (fastcoexist.com)

kodiaktau writes: This week the Lifeboat foundation announced that Stephen Wolfram would be joining its organization. The purpose of the group is to think through scientific solutions to existential problems that might be used to save humanity from such risks as asteroids hitting the earth or some other diabolical disaster. Wolfram brings computational science to the table and has posited that the earth and universe can be understood as a computer program that can be significantly altered as we continue to advance in technology.

You have to think brand name, NASA as a brand is a big plus. They could initially have just the space-food, then they could branch out to camping food as well, where they could basically sell the food you are used to, but with the NASA brand, they would probably make more money.

The only down side I can see is that many would object to the federal government going into business, and competing against private companies. So what they could do instead is to license the NASA brand. I'm sure NASA could make some money off of this. It might reduce our taxes (although minimally). I think licensing a brand like NASA is akin to other licensing agreements the feds are already doing. As long as they don't dilute the brand, or put it on bad products, we may as well make some money off of it as it is a national resource.

Comment Not the first 3D version of Mario (Score 1) 83

See http://en.wikipedia.org/wiki/Mario's_Tennis

"Mario's Tennis (, Mariozu Tenisu?) is a game for Nintendo's Virtual Boy video game console."

The Virtual Boy video game console provided true 3D display for its games, although in monochrome. It did not require glasses either. It had two displays one for each eye, and you had to look through a neoprene coated eyepiece to see the displays. It didn't do very well, so is not well-known. It was one of the few flops for Nintendo.

I went one better, I used a telescope to burn all sorts of things. It has a somewhat adjustable focus by using different eye pieces, and I could burn wood, and paper, and many other things on a sunny day. The telescope was readily available, so I didn't need to build anything. It was only a 2" refractor, but had plenty of power, much more than a magnifying glass, with a MUCH sharper focus. I did manage to melt metal with it as well.

I always meant to revisit these experiments with something like a 10" or larger scope. I would imagine some really high temperatures would be possible, the optics count for a lot in efficiency.

Comment Re:All you need to know, from TFA (Score 1) 815

Many times the reason for a rejection of a paper like this is failure to properly control for possible anomalous conditions. If you don't have an explanation, the minimum you should do is to control for every possible other explanation. If you haven't fully tested whether the phenomenon you observe might be due to something else, then a reviewer must reject the paper.

It is equivalent to the famous Sherlock Holmes quote, “Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth.”

If you haven't eliminated the impossible, you can't conclude you have found improbable physics.

If you are a criminal:

Plan 1: Hack into google cloud or some other easier to hack supercomputer, or your own botnet, use that to crack credit card or bank security ==> Free money!

Plan 2: Use cheap cloud computing as your own supercomputer. If you can get $1000s for $1s it is a win for a criminal.

I know of someone who has already used cloud computing to crack wireless security for about $1 just as a proof of concept.
Computing as a commodity is here, and decreasing in price, and available to all.

Comment Re:Math always a part of CS ... (Score 1) 700

I know of CS programs still in the Math department today, also some in the college of business. Here at Ohio University in 1996 CS moved from Arts and Sciences to Engineering. At the time, the degree was very much still aligned to Math which it grew out of. Our university is now moving to semesters, and as part of the curriculum redesign we have moved to a curriculum much more like engineering than A&S. We still have a large math component. It is possible for our students to get a minor in math with just a couple of more math classes than we require for CS.
