Comment Re:IT employees rejoice (Score 1) 220

Of course you're right to ironically point out that tax payers money should have been better spent, especially for struggling sectors.

In that case I would rather have mixed feelings: too bad for the country, those wasted resources are a shame. Still good news for IT jobs.
And employees are not the ones to blame. We are not parasites fed in an ecosystem maintained by a deficient management. Or are we?

Submission + - Ask Slashdot: When is Patent License Trading not Trolling? (forbes.com) 1

LeadSongDog writes: A piece in yesterday's Forbes offers arguments on why not all "Non-Practicing Entities" are "Patent Trolls". Comments here on such businesses are often critical. Is there a right way to trade in patents for profit without abusing the process?

An anonymous reader writes: I made this comic about Steganography (and the NSA/PRISM) however the really interesting thing is that in the comic I hid an image using the steganography system loosely described in the comic. Can you solve it?

It doesn't require a huge degree of computing programming talent to solve, I wrote an encoder / decoder in javascript using the HTML5 canvas.

Submission + - Physicists Discover Geometry Underlying Particle Physics (simonsfoundation.org)

Lee_Dailey writes: Physicists have discovered a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality.

“This is completely new and very much simpler than anything that has been done before,” said Andrew Hodges, a mathematical physicist at Oxford University who has been following the work.

Submission + - Brazil announces plans to move away from US-Centric Internet (time.com)

trbdavies writes: Associated Press reports: "President Dilma Rousseff ordered a series of measures aimed at greater Brazilian online independence and security following revelations that the U.S. National Security Agency intercepted her communications, hacked into the state-owned Petrobras oil company’s network and spied on Brazilians who entrusted their personal data to U.S. tech companies such as Facebook and Google. The leader is so angered by the espionage that on Tuesday she postponed next month’s scheduled trip to Washington, where she was to be honored with a state dinner." Among Brazil's plans are a domestic encrypted email service, laying its own fiber optic cable to Europe, requiring services like Facebook and Google to store data generated by Brazilians on servers located in Brazil, and pushing for "international rules on privacy and security in hardware and software during the U.N. General Assembly meeting later this month."

Submission + - Lockeed "Skunk Works" Announces Fusion Power Demo in Five Years (fusenet.eu)

Required Snark writes:

At the recent Google “Solve for X” conference on February 7, Lockheed Martin's long-term R&D department (“Skunk Works”) announced they are working on a compact fusion reactor. With what seems a 4th generation prototype called "T4", the aerospace giant says to have developed a high beta configuration, which allows a compact reactor design and faster development timeline.

Public reactions describe the announcement of their activities on nuclear fusion remarkable, because Lockheed Martin doesn't usually make public announcements about Skunkwork projects unless they have a high degree of confidence in their chances of success. The developement timeline indicates plans to have a prototype 100-megawatt nuclear fusion machine of Lockheed Martin tested in 2017, and that a fully operational machine should be grid-ready ten years from now.

Some of the properties reported from the presentation:

  • A self-tuning feedback mechanism whereby the magnetic field increases the farther out that the plasma goes
  • Novel magnetic field configuration that has very few open field lines compared to tokamak design
  • Very "good arch curvature" of the field lines The system has a beta of about 1
  • System is working with D-T fuel

Although the presentation is short on details, Lockheed Skunk Words has a phenomenal track record, and they are putting their reputation of the line when they make this kind of announcement at a high profile Google event. A video of the presentation is here.

Submission + - A new way to fund open source software projects, bug fixes and feature requests

Lemeowski writes: Open source software projects are seeing some success on fundraising sites like Kickstarter and Indiegogo. But Warren Konkel believes open source software needs a better funding model that's more aligned with how software is built. So Konkel, who was the first hire at LivingSocial, teamed up with his friend David Rappo, a producer for games including GuitarHero and Skylander, and founded Bountysource, a crowdfunding and bounty site specifically designed to help developers raise money for thier OSS projects, bug fixes and feature requests. In this interview, Konkel talks about how he recently snagged a $1.1 million investment in Bountysource, gives developers tips on launching a fundraising effort for thier OSS project, and more.

Comment Re:Biolite anyone (Score 1) 147

Biolite team has done extensive field test for their homestove, it really works (and rocks) for those people who do the daily cooking with wood stove.
And they use it to charge their cell phones and home light batteries, while saving on wood.

I use the summer camp smaller "geek" version of this stove, I'm happy with it even if it has some limitations the home version hasn't.

Comment Great USENIX study on SSD under power fault (Score 2) 512

Out of 15 SSD tested, only 2 are failure proof under power fault (only one maker and model).
(yes, I've read the pdf)

I'd like to know who is the winner, the anonymous vendor/model called "A-2".
It is not the most expensive, almost the cheapest, but it has at least a power-loss protection.
Another vendor has power-loss protection but his models failed the tests.

Direct link to pdf and figures erratum.

Bit Corruption: SSD#11, SSD#12, SSD#15
Flying Writes: none
ShornWrites: SSD#5, SSD#14, SSD#15
UnserializableWrites: SSD#2, SSD#4, SSD#7, SSD#8, SSD#9, SSD#11, SSD#12, SSD#13, HDD#1
Metadata Corruption: SSD#3
Dead Device: SSD#1
No failure: SSD#6, SSD#10, HDD#2

Their last word conclusion :

We recommend system builders either not use SSDs for important information that needs to be durable or that they test their actual SSD models carefully under actual power failures beforehand. Failure to do so risks massive data loss.

Thanks again for this link to the Usenix study, too bad you posted anon (patent need mod up).

Comment Not inner waves. Two actions at work. (Score 2) 43

This isn't inner waves, but water moving back and forth in a U shaped tank (water is pushed by compressed air on the tops of the U shape, alternatively).
So there's no wave at all in the tank.

I just wonder:

Is the counter-reaction mainly cause by the counter-weight of the water which fills only one side of the U tank, or by the momentum (acceleration) given to the water rolling in the tank ?
In either case, it could be more easily done with some solid weight on rails, with less energy lost (air compression and fluid displacement).

Comment Intent-aware OS and I/O bottleneck aware kernel (Score 4, Interesting) 226

If I copy huge files, while doing video processing, running a VM, and switching from one tab to another in the web browser, the system become quite unusable...
He could still be responsive with dynamic I/O priority handled by GUI and kernel.

What we lack most is some intention-aware GUI and OS kernel, working together so that the right process get the right priority and that I/O bottlenecks are handled gracefully.

Content creation activities are often I/O and CPU demanding, and even on creativity praised OS such as Mac OS we have this big problem of I/O channel unawareness.

Example:
One need to be able to start a huge file copy with a background intent so it will be throttled when the user starts a video effect preview which writes temporary files on one of the same disks of the copy.
The GUI gives the video preview higher priority, even on I/O, and the kernel detects the bottleneck on one of the disks and decide to almost freeze the file copy.
But then the user start the full video rendering in background, the GUI assigns the lower priority and the file copy resume to full I/O speed.

Comment Re:Cube is worst shape for cooling (Score 1) 197

Apple, in their next Mac, is considering a cylindrical tower, w/ an internal 3 plane cooling that cools everything.

Nice design, with the heat sink in the core like a funnel or chimney.
Its shape isn't compact, the cylinder is hollow, and this is not passive cooling :

"The form factor also echoes the shape of the single large fan located in the bottom of the machine." ref
