Ask Slashdot: How To Bequeath Sensitive Information?

selectspec Re:Safety Deposit Box (208 comments)

This is by far the best approach out of all of the recommendations. Obviously, sending paper documents (or USB drives) via overnight delivery is relatively immune to intercept, but what if you relatives leave the documents out in an unsafe area? The best place is a safe deposit box, along with any portable valuables (nice watch, jewelry, etc). You can arrange in your will to have your estate trustee then disseminate the contents.

Ask Slashdot: In What Other Occupations Are IT Skills and Background Useful?

selectspec Zombie Apocalypse (158 comments)

Actually, IT skills are entirely useless in any kind of an apocalypse, unless other people with other skills manage to restore power.

Scientists Find Method To Reliably Teleport Data

selectspec Re:How fast is the data transmitted? (202 comments)

The problem with the articles is that they use a misleading term "information". The quantum information is transmitted instantaneously. However, quantum information is not the same as classical information. Classical observers at either end of the experiment cannot set the quantum information that is transmitted. Therefore the no-communication theorem is not violated. Superluminal communication of classical information (what you and I think of as data) is not possible. The best way to think of this (as another slashdot user pointed out) is that you have a random number generator at two points separated by a distance. Both points generate the same random number regardless of how far away from each other they happen to be in space.

The practical application of this is not transmitting classical data faster than the speed of light (as that is not possible.) However, it could be used for an encryption mechanism that is unbreakable. This is done by taking the random numbers generated and using them to encrypt classical data, which is then transmitted by conventional means (radio etc) and then decrypting on the other end with the same set of random numbers. Nobody can decrypt the data unless they have the other entangled particle of which there can only be one.

Physics Forum At Fermilab Bans Powerpoint

selectspec LHC is at CERN (181 comments)

The LHC is at Cern. Maybe they should ban a bi-weekly forum on CERN's activities and focus on activities at Fermi lab?

China: The Next Space Superpower

selectspec How about postal addresses? (250 comments)

This is typical authoritarian bravado. China invests heavily in a field that generates PR for nationalistic pride (with a dual military purpose.) Meanwhile, they don't even have a postal address system. Don't be fooled by the hype. Yes, their economy will be the largest, simply due to their numbers. (If the Chinese simply earned per capita one third of the US average income, they'd be a larger economy than the US.)

NSA Collect Gamers' Chats and Deploy Real-Life Agents Into WoW and Second Life

selectspec Arma maybe (293 comments)

I could sort of understand if the NSA were snooping on Arma III. Arma likely is the military training in most 3rd world countries. Another reason to ban side chat.

For First Three Years, Consumer Hard Drives As Reliable As Enterprise Drives

selectspec Re:Common knowledge (270 comments)

In the business, this is called duty cycle, and there are significant MTBF differences between enterprise quality drives (FC, SAS) and consumer drivers (SATA, NL-SAS) at high duty cycles.

If you are running a server like a SQL database, an Exchange server, or a Host like ESX or HyperV with a good number of guest vms, then the disks are going to be active much of the time. This high duty cycle will wear down the low end drives over time.

MenuetOS, an OS Written Entirely In Assembly Language, Inches Towards 1.0

selectspec LincolnLogOS, an OS written entirely in linoln log (372 comments)

LincolnLogOS is an open source, GUI-equipped, wooden operating system written entirely in Lincoln Logs that can fit on any play room floor (if you have one big enough). I originally spoke to its developers in 2009. Recently I had a chance to catch up with them to chat about what's changed and what needs to be done before the OS hits version 1.0 after 13 years of work. The system's creator, Ville Turjanmaa, says, 'Timeframe is secondary. It's more important is to have a complete and working set of features and applications. Sometimes a specific time limit rushes application development to the point of delivering incomplete forts and buildings, which we want to avoid. ... We support USB devices, such storages, printers, webcams and digital TV tuners, and have basic network clients and servers. So before 1.0 we need to improve the existing forts and buildings and make sure everything is working fine. ... The main thing for 1.0 is to have all application groups available.

Warm up the Nobel Prize: Data Teleportation

selectspec selectspec writes  |  about 7 months ago

selectspec (74651) writes "Researches in the Netherlands are claiming to have achieved quantum teleportation of data over a distance of 3 meters without any data loss. They plan on upgrading the experiment to distance of a kilometer. This would prove the famous "spooky action at a distance" theory of quantum mechanics. In laymen terms, this is moving information over distances faster than the speed of light, or rather instantly. Practical applications include phone calls across the global without delays, the end of bandwidth-delay-product issues in networking, and controlling rovers on Mars in real time, not to mention that Mr. Snowden and his former friends can't snoop in on this conversation."

New research into creating Hydrogen gas from water using sunlight and rust.

selectspec selectspec writes  |  about a year and a half ago

selectspec (74651) writes "Despite being the most abundant element in the universe, creating Hydrogen gas here on Earth is a relatively expensive process. While Hydrogen can be cheaply produced from hydrocarbons like natural gas, extracting it from water has proved tricky with most methods being rather inefficient and impractical. Some new research has emerged involving a process involves nano-materials made out of rust (iron oxide) immersed in water exposed to sunlight. The process is 15% efficient in terms of capturing the solar energy, which isn't bad considering current generation photovoltaic solar panels operate around 20% efficiency."
