Sulfur Polymers Could Enable Long-Lasting, High-Capacity Batteries
In the 1960s there was research into sulfur-based polymers but apparently ran into some problems:
"Recently we found ourselves with an odour problem beyond our worst expectations. During early experiments, a stopper jumped from a bottle of residues, and, although replaced at once, resulted in an immediate complaint of nausea and sickness from colleagues working in a building two hundred yards away. Two of our chemists who had done no more than investigate the cracking of minute amounts of trithioacetone found themselves the object of hostile stares in a restaurant and suffered the humiliation of having a waitress spray the area around them with a deodorant."

Ask Slashdot: Legal Advice Or Loopholes Needed For Manned Space Program
... and the easiest way for your government to comply with the treaty article about non-government entities is to simply to put in place a law disallowing it. Without a powerful lobby there will be no incentive for your government to set up the regulatory apparatus for legally enabling such activity. Any such regulation is likely to be tailored to the needs of the members of such a lobby, not to a small organization like yours. And if you are thinking of jurisdiction shopping (i.e. finding some government more friendly to such activities) remember that your government may decide that you are under their jurisdiction by being a citizen, regardless of where in the world you happen to be. Also, other countries (most notably the US) are likely to decide that if you are building anything with a range capable of reaching their territory in ballistic flight that makes it their business, too. They will find many creative ways to put pressure on other governments to stop you (see this for example).
Royal Navy Deployed Laser Weapons During the Falklands War
"The pity was that Plymouth had not had time to turn right around, because she was fitted with the new laser equipment known locally to us as "Flasher" - which could well have stopped the attack in its tracks, because it literally forces any incoming pilot to pull up sharply during the forty-second period in which he cannot see."

OmniCam360 Camera Cluster Lets You Choose the Viewing Angle
The application was a video conferencing system. The omnidirectional camera had the exact same arrangement of mirrors and black baffles between them. It was placed in the middle of a conference table and the display was steered automatically by a microphone array that determined the direction of the speaker. This way you always got a nice framing of the speaker's head. It was essential for getting any kind of usable picture in a conference with multiple people back when bandwidth was limited and video compression was crappy. It would still be very useful today but I haven't seen this anywhere.

In the back of your mind, you havenâ(TM)t got Raspberry Pi 2?
No, not Pi 2. It must obviously be named 2 Pi.
Oracle Discontinues Free Java Time Zone Updates
Not to mention great support for firewall traversal. It gets even into many places that HTTP does not.

DNS is a great protocol for distributing a relatively small piece of infrequently changing information to a very large number of clients. It has a global infrastructure of caches, supports delegation of authority. Sounds like a good match.
Electric Car Startup 'Better Place' Liquidating After $850 Million Investment
Why would he bother? He has a successful company, why would he want to buy a company that burned through that much money with no noticeable product
As a slashdotter, we are prone to having a bias of looking at everything as a technology development issue. But Better Place was an infrastructure project. They tried to minimize the development of any new technology. And infrastructure requires Big Money. Unfortunately, it was Big Money with the risk profile of a technology development startup. Ouch.
Physicists Create Quantum Link Between Photons That Don't Exist At the Same Time
Superposition, wave function collapse and other quantum effects are supposed to govern everything. But I don't seem to recall any such weird experiments that do not involve any particle traveling slower than the speed of light.
Are there any such demonstrations that involve only interactions between particles having nonzero rest mass?
Ask Slashdot: Moving From Contract Developers To Hiring One In-House?
Make sure to explain the scenario to the contractor up front. In detail. More than once. Give them a chance to raise their offer to include this. Ask them again how certain they are about their ability to estimate their bug rate. Let them sign a separate page describing this in simple language.
Have a process to clearly separate bugs that are covered by this from modifications for which they are paid separately. For some small things that are arguably not bugs but modifications let them have the benefit of the doubt and pay them for it, anyway. Make sure they know it.
I think it can be done.

A Tale of Two Tests: Why Energy Star LED Light Bulbs Are a Rare Breed
If you are investing in a light source that will not need replacement for a decade then why, exactly, do you care so much about it being shaped like a light bulb?
LEDs don't like heat. Packing the equivalent of a 100W incandescent in a shape that pretty much minimized surface are to volume ratio is a very bad idea for heat dissipation.
LED light panels make much more sense.
Nuclear Power Prevents More Deaths Than It Causes
Construction of the first Westinghouse AP1000 reactor unit at Sanmen Nuclear Power Station started at April 19, 2009. It is planned to go online at October 2013.
The AP1000 is a pressurized water reactor using passive cooling and safety systems i.e. it does not rely on engineered systems like pumps or electricity for safety - only passive effects like gravity and convection.
Yes, it's a big upfront investment. But ongoing fuel costs are negligible so the overall cost of produced electricity is not much more expensive than coal. If you add the health and environmental costs of coal that are forcibly paid by your neighbors then nuclear is cheaper. Of course, if construction is delayed for 12+ years because of incompetent regulation the interest costs of that delay will balloon out of proportion.
BTW, my signature line below has not changed in the last couple of years.
Cambridge University Scientists Find Quadruple Helix DNA In Human Cells
(DNA = Douglas Noel Adams)
Haggunenons have the most impatient chromosomes in the Galaxy. Whereas most species are content to evolve slowly and carefully over thousands of generations, discarding a prehensile toe here, [...] hazarding another nostril there, the Haggunenons would have done for Charles Darwin what a squadron of Arcturan Stunt Apples would have done for Sir Isaac Newton. Their genetic structure is based on the quadruple sterated octohelix....
Congress Asks Patent Office To Consider Secret Patents
There is a little known form you can find on the USPTO that lets you ask for your patent not to be published until granted, just like in the old system. If not granted you can still try to keep it a trade secret.
The catch is that you can't use the filing date as the priority date for international patents. The reason patents are normally published after 18 months is because of international patent treaties.
IIUC, this proposed change is meaningless - you can already get it now if you are willing to give up international priority and keeping patents secret and still getting priority is impossible without renegotiating those treaties.
Why We Should Teach Our Kids To Code
We live in a world of information. So let's teach them about information. What's the meaning of information? How has it been encoded, stored, reproduced, processed and transmitted throughout history?
It should include some material about the concept of processing information by an algorithm, but I'm not sure actual programming classes are really for everyone.
