Comment Re: please keep closed! (Score 1) 50

This is cool for a project I am working on. I plan to see if I can create a .com that will do business transactions. I need no latency but at the same time require ACID to ensure each transaction will be written to disk :-(

My Idea is to have no sql and sql databases where something like this will do the transactions to ACID.

This is needed at the bar when pouring into a glass or pitcher.

By then it's far too late. This is about spreading out the active ingredient from the hops during the original mixinig, before brewing, so it can keep the ingredient from the fungi from loading up on carbon dioxide during brewing. By the time you pour, the opportunity for the hops to do anything but add flavor is long gone.

Comment All valid except one point: (Score 1) 225

Nearly all of what you say are valid points. But one carries a misconception:

By it's very nature of being a focused, collimated beam a laser does not affect anything in "the general direction" of the target - if it was not focused and accurate, it wouldn't be an effective weapon and might not even be dangerous.

That's SO not true. There are two issues here:
  - Forward (and back) scatter: A laser beam "leaks" light, primarily in the "general direction" of the main beam and, to a lesser extent, in the general direction of back toward the source. It's not a big percentage. But when you start out with kilowatts of colimated light it can be more than adequate to burn out a human eye.
  - Scattering (also specular reflection) from the target, or the cloud of gas that remains of the target. This can be a substantial fraction of the incident beam.

"Do not look at the beam or the target with the remains of your face."

Comment I don't see the problem (Score 4, Interesting) 135

Deuterium/Hydrogen (D/H) isotope ratio is significantly higher (more than three times, in fact) than that of water found on Earth.

Q: How do you separate heavy water from light water?
A: Distillation. Light water boils off / evaporates more easily, because the molecules are lighter, and leaves the heavier water behind.

Why shouldn't this be true of vacuum sublimation as well?

Leave a chunk of dirty ice orbiting the sun in a hard vaccuum for a few million years, with the water quietly sublimating away. Seems to me the result would be that last remaining chunk of dirty ice would have a substantially larger fraction of heavy water molecules than the water on the planet where the deep gravity well hangs on to the lighter molecules.

Is it enough to explain a 3:1 enrichment? No clue. But I'd like to see that the analysis was done and what the scientists' estimates were.

(Not to say they ignored it. The last time I raised a similar question about a scientific paper reported here it turned out that the scientists HAD examined the issue.)

Comment Violation of the "Takings" clause. (Score 1) 178

This will cost us billions of dollars in the private and public sector,

who is this "us" he is talking about?

The taxpayers. It's a clear violation of the "takings" clause of the US Fifth Amendment (long since incorporated against the states and their subdivisions, including the City and County of Los Angeles.) This means, after a bunch of legal wrangling, the courts are very likely to rule that applying such a law against a pre-existing building is a "partial taking" and the government must make the owner whole, i.e. reimburse him for his costs of compliance.

The takings clause:

No person shall ... be deprived of ... property, without due process of law; nor shall private property be taken for public use, without just compensation.

if the public good is really being served here by improving safety of citizens, why isn't the discussion framed more along these lines?

When it gets to the courts, it will be. Count on it.

Comment This might alienate anti-ISI* Muslims. (Score 2, Interesting) 225

One of the religious prohibitions in Islam is making war with fire.

If this is used it will be interesting to see the effects on recruiting by the Islamic State and other anti-US organizations among those Muslims who are currently either opposed to them or unaligned.

Also: How do you keep a 30 kW laser, at any frequency, from blinding everybody in the general direction of the target? The last I heard, weapons that blind are banned by the current "laws of war" as recognized by the western powers - and that's been the major impeidment so far to deploying laser (and other directed energy) weapons. Has something changed? Or did the current administration just decide to play with the new toy despite past promises to the other kids?

Comment Re:How about a straight answer? (Score 1) 329

You are asking a group of people who believe the world is no more than 5,000 years old and there is no evidence (in their eyes a serious intellectual way) that humans evolved from primates for a straight answer why they do not believe? Especially since those that due are liberal which are obviously wrong all the time in their opinion just look at obamacare etc so there is zero credibility.

It is an embarrassment such a solid group even exists in my country! I just can not fathom this in the 21st century people who are afraid of change but they exist and are very gullible. The same political party also supports big business and oil and the other half who votes believe whatever they hear on Fox, Rush, and their church pastor who also gets his information from the same sources who are funded by the energy industry. In other words they perfect combo.

My point of this post is not to go offtopic but to point out it is political. Not scientific. You can't argue with gullable people who think facts are not fact. Only gut feelings.

FYI I am not bashing libertarians who may want to mod me down. I am bashing those in the same wing politically who are social conservatives.

They are. They paid frys and best buy to destroy copies of win 7 and office 2010 to force users to run an OS for tablets.

Like firefox developers will stop focusing on writing for a single browser or os version. Everyone will constantly upgrade.

If they don't Android and I OS will win. SC will probably be tied to updates more to make the transition easier. Look at win 8? Update every 6 months and new version every year.

Comment Re:How ? It doesn't have 3G / WiFi. Needs a router (Score 4, Informative) 47

How is this "directly connected to the internet" when it is using a router to access the net.

By that definition, NOTHING connects directly to the internet.

Anyone with a better understanding care to explain ?

The proper definition of a host running an internet-facing application being "directly connecting to the internet" is using IP for the first hop, with the packets having a route from there to and from the rest of the Connected (capital-I) Internet.

Bluetooth 4.2 added support for IPv6 to/from bluetooth devices. This means IP packets formed on, or directed to, the Bluetooth 4.2 hosts, for delivery to/from other Internet-connected devices, do not require a protocol-translation gateway to select and translate some subset of the packet types, services, and features, modifying the transport semantics to support some tiny subset of functionality that the gateway explicitly understands. An IP packet formed on the bluetooth device goes all the way to its destination semantically unmodified, and ditto packets going from some other device to the bluetooth device. The full feature set of IP (or as much of it as the stack implementer choses to support) is available, while the routers can be "as dumb as rocks" and totally ignorant of what the application on the Bluetooth device is up to, in classic Internet style.

A Bluetooth 4.2 device, using IPv6 and with a route, IS on the Internet, and is a peer to all other internet-connected hosts.
