Comment Or Jotti Re:Upload to virustotal.com (Score 2, Informative) 255

I agree, virustotal answers the original question of an online-resource to check a file. A similar scanning service is http://virusscan.jotti.org/. Remember, take the answers with a grain of salt. These are both multi-scanner services, in which the file is examined by multiple virus-scanning software packages.

Comment Running Very Lean Re:Same old snake oil (Score 5, Interesting) 379

It's been known for a long time that engines will run very efficiently if you run them very lean. In TFA, you will see that's what these guys are doing. The problem is that the engine then runs very hot, and the thing wears out in short order, or you have to make it out of unobtanium. They are also using unusually high pressures and temperatures. In the fine print, you will see they still have some work to do on verifying that the engines will last very long under this treatment.

So, yes, it will get great miles/gallon, but probably not very many miles/engine.

Comment Latency Re:Bad deal for AT&T (Score 1) 220

Dirty little secret: All cell phone carriers have high latency for voice. And it's double if both ends are cell phones. It's really annoying, and makes you talk over each other.
Anecdotally: I had a cell phone conversation going simultaneously with a Skype video call from my desktop computer, and the audio via Skype was noticeably faster than the audio through the cell phone. I heard the other end first through Skype, and somewhat later via phone. (My end was Verizon.)

Comment Available Cartridges Re:The best laser printer is (Score 2, Informative) 557

The joke translates: find one with readily available cartridges. :) If you have a little more volume, the issue becomes cost of consumables. Toner and drum cartridges are expensive, and often proprietary. Next printer, go to visit your local Cartridge World, or similar cartridge recycling vendor, and ask them: "What cartridges are cheapest, and most readily available, with no proprietary crap making them unrefillable?" Then, go buy the printer that uses them.

Comment Post files on internet (Score 1) 633

If you want to preserve digital data, post it online. Give the files some whacky, unique keyword that she can search for when she is 17. Put the keyword in the box. Once stuff is on the net it never seems to die. Everybody's ancient USENET posts are still available. And somebody else is responsible for updating the storage medium occasionally.

Submission + - Cryptologist Solves 200 year-old Unsolved Cipher (wsj.com)

AJ Mexico writes: "For more than 200 years, buried deep within Thomas Jefferson's correspondence and papers, there lay a mysterious cipher — a coded message that appears to have remained unsolved. Until now. The cryptic message was sent to President Jefferson in December 1801 by his friend and frequent correspondent, Robert Patterson, a mathematics professor at the University of Pennsylvania. President Jefferson and Mr. Patterson were both officials at the American Philosophical Society — a group that promoted scholarly research in the sciences and humanities — and were enthusiasts of ciphers and other codes, regularly exchanging letters about them."

Comment It is Happening Re:It's Not Global Warming! (Score 1) 612

It is already happening. The International Dark Sky Association http://www.darksky.org/ has been working for years to reduce wasteful lighting. Some locations have already adopted their model lighting ordinance.

We are paying *lots* of money for oil to light up the sky at night (which helps no one). In the USA, this is mostly imported oil. So, in the current economy there will be a lot of pressure to stop wasting money and oil, and stop producing greenhouse gasses, etc.

Comment Other Analog computers (Score 1) 2

As I recall, some anti-aircraft mounts used clever mechanical analog computers to achieve a firing solution. I think some Russian models were doing this after the west was using digital.

Automatic transmissions in cars were essentially analog/digital hydraulic computers, until recently. They made discrete decisions (which gear?) based on analog inputs.

In the early 80s, at least, analog (electronic) computers were still used to simulate aircraft flight characteristics. I worked on a project that used one. (We were implementing digital flight controls on a Zilog Z-8000.) I wouldn't be surprised if they still had applicability in some areas.

Comment Simulator Dome (Score 1) 1127

It wasn't me, but I visited General Dynamics, Ft. Worth, in the '80s. The engineers desks were crammed together in the open bay of a big hangar. We took a tour of the simulator dome, where F-16 simulations were in progress. We had to step over a guy crouching on the floor with his keyboard and emulator. He was trying to work inside this dome with simulated yanking and banking going on, complete with sound effects, while people stepped over him.
