Hard liquor consumption shot up during prohibition

Not so fast there. I've heard that thrown out before without any justification. Please tell me how consumption of an illegal beverage was accurately measured _during_ Prohibition? I don't think any government statisticians were walking into speakeasies and measuring things. (Gallons seized/destroyed would not be a reliable proxy, I wouldn't think.)

(And I'm sure the government had no incentive to fudge the numbers after it ended Prohibition, in order to justify its decision. Nah, they wouldn't do a thing like that! Nor would any academic researchers have bias here...)

Seems like there would be a _minimum_ shaking velocity of the fur itself, just to dislodge the water. Anything faster than that would also work, but expend more energy.

You also have to take into account the fact that with each oscillation, the dog's trunk reaches some maximum stretch limit, at which time muscles in the reverse direction kick in and make them go the other way. But the maximum velocity would be reached somewhere near the middle of an oscillation.

Wouldn't you model this more like a spring or pendulum, where maximum velocity occurs near the middle of the cycle?

Wait...I'm taking this way too seriously.

That's why important passwords should never be directly memorized. Always put some cognitive distance + time distance + physical distance between you and the password. (Except when you're actually entering it of course.)

You can do this by making a puzzle of some sort using memories that only you would possess (childhood, etc.) Solving the puzzle might take the form of arranging the memories in chronological (if they're events) or physical order (if they're places or objects). Once correctly arranged, the password is then extracted from that, as a hash of some sort (in order to guarantee enough entropy). (Of course there would have to be enough entropy available in the original puzzle so that a computer could not try every possible ordering.) Salt to taste.

This involves creating a puzzle, and that would be time-consuming, but software could help there. But once created, it's not something you could reconstruct in a few seconds, nor solely from memory. You would have to have the written puzzle clues in front of you, plus some time to concentrate. This doesn't mean you couldn't be compelled to reveal it, but it would raise the cost to an adversary in getting you to reveal it.

Submission + - Sikorsky copter sets unofficial speed record (gizmag.com)

SlideRuleGuy writes: No flapping wings on this baby:

Sikorsky Aircraft’s coaxial X2 Technology demonstrator has achieved the 250-knot (287.69 mph) milestone that was established as the goal of the craft from its inception. The speed, which was achieved in level flight during a 1.1-hour flight on Wednesday, September 15, is an unofficial speed record for a helicopter, easily beating the current official world record that stands at 216.46 knots (249.1 mph) set by the British built Westland Lynx ZB-500 in 1986.

But I'm sure it's no match for Airwolf.

Submission + - Research Experience for Grad School

An anonymous reader writes: I want to pursue a Ph.D. in computer engineering, but I'm concerned that I don't have the academic research experience sought by admissions committees for top programs. I applied to five schools after completing my masters five years ago, and I was rejected by all but the two lowest-ranked programs. At the time I had two bachelors degrees (EE and CS) and a masters (EE), work experience, college teaching experience, a very high GPA, and very good GRE scores. However, I didn't have university research experience. Since then I've been working in industry as an R&D engineer at a somewhat well-known company. I want to try again, but before I do — what should I be doing to increase my chances of acceptance? I'd love any advice from people who have been through the process.

Submission + - Web standard gets EU funding (bbc.co.uk)

gbjbaanb writes: The BBC is reporting news of project Webinos, an initiative to provide a common platform for web applications that would sidestep current operating systems and allow devs to create web-based apps that would run anywhere — PCs, TVs, cars, mobiles.

The project aims to sidestep operating systems and proprietary app stores by providing a web-based approach.

The idea would enable a given app to work, for example, on a web-ready television, in a car and on a mobile, no matter the makers of the devices... Companies can afford to have an app on two or at most three platforms — they're extremely costly to develop and ensure the user experience..


Makes sense for all, except companies that thrive on having their own, proprietary systems to 'differentiate' themselves from the other proprietary systems.

It's all about the quality of your people and the financial state of the organization maintaining it. I have seen small applications (~30KSLOC) that a team of people with 10+ years of experience each could not keep running beyond 7-8 years. It collapsed under its own weight. Nobody had the skills/wisdom to refactor the code periodically, nor did the organization have the money to be able to afford it. (In fact, their poor financial state meant that they never hired the best developers. They had to take what they could afford.)

I have also worked at a different company that kept a system (3 million SLOC) going for over a decade with only periodic refactorings of portions of the system. They had good the financial status to be able to afford it, plus the skill levels to know when/how to do it. (And their good financial state meant they could --and did, hire better developers.)

The quality of one's engineers and the prosperity (or lack thereof) of the organization determines how long you can hold off "software entropy" and keep software evolving forwards.

Bollocks. When a tax, by definition, only affects the top 2%, it ONLY AFFECTS THE TOP 2%!

Are you saying that when a tax by definition only has to be paid by the top 2% of wage earners (let's say), that it has no other effect on the economy as a whole? Econ 101 factoid: when the structure of taxation changes, people's investing and purchasing behavior changes. Plus, the rich have the greatest flexibility in switching their investments and altering their purchasing behavior.

Submission + - Man swallows USB flash drive evidence (thesmokinggun.com)

SlideRuleGuy writes: "In a bold and bizarre attempt to destroy evidence seized during a federal raid, a New York City man grabbed a flash drive and swallowed the data storage device while in the custody of Secret Service agents, records show... Florin Necula ingested the Kingston flash drive shortly after his January 21 arrest outside a bank in Queens, according to U.S. District Court filings...A Kingston executive said it was unclear if stomach acid could damage one of their drives. 'As you might imagine, we have no actual experience with someone swallowing a USB,...'"
I imagine that would be rather painful. But did he follow his mother's advice to him as a child, and chew thoroughly first? Apparently not, as the drive was surgically recovered.
