In component markings and listings, especially where the decimal point would easily rub off or go unnoticed, leading to an order-of-magnitude error, there is a practice of substituting a unit abbreviation for the decimal point. Thus, 2.7 K is often written as 2K7. Likewise, "R" is used for the omega sign; a common way to denote a 2.7 ohm resistor is 2R7.
Recognizing counterfeit money is a specialization within the FBI. Also, there are few fake $20 bills, not worth the effort. They usually counterfeit $100s. And ever been in a casino where they authenticate with that special marker? This is because you can't tell unless you've got years of experience. We've all probably handled counterfeit money in your lifetime without ever knowing.
There's counterfeit and there's counterfeit. Recognizing a good counterfeit bill is hard, but you might want to do some elementary checks yourself nevertheless. Even if I'd never seen dollars before, I'd be suspicious of a note where it says "200 twenty dollars", the last zero of "200" drawn with a marker... Then again, if somebody bribed mint workers to print a few sheets of "genuine" notes "off the record", they'd be identical to real ones, wouldn't they?
A small denomination is no obstacle to counterfeiters. Some people have been counterfeiting Euro coins. Euro banknotes are also being counterfeited, and people have gotten counterfeit bills from banks.
...the whitelist mechanism will be cracked, and what you thought was Solitaire is really spam, Solitaire and spam.
I can see some immediate problems with trusting a list that says "you can only run these known safe programs":
Users disabling the whitelist when programs they want to run aren't listed. (E.g. self-made, custom, or legacy software.)
Malware being run in environments not controlled by the whitelist. (E.g. various macro languages, Javascript, XSS, ActiveX...)
Malware squeezing itself into the whitelist. (As a Trojan, or bypassing the whitelisting mechanism altogether: e.g. breaking out of a virtual machine.)
The viability of these phones as a platform depends on whether they manage to attract a large enough user and developer base to have a sustainable "ecosystem" of application development. Time will tell...
This will depend on your definition of "easy"... if it means "in less than five passive components", then you may be right.
Anyway, you mentioned the railway engine's AC-DC-AC drive. Now, to run on DC, just skip the first rectifier: you can run the inverters directly on DC. In fact, many railroads do just that. There are lower-powered inverters and motors available for lighter-duty applications. Did you know your average "brushless DC" CPU fan is in effect an induction motor with an integrated drive?
So, if you have a 500 V battery pack capable of 10 A, just slap a 5 kW drive with a suitable control input and a 5 kW induction motor on it and you're basically done. (Select ratings to suit application and products.) Ask your supplier for more information.

The value of IT in an organization is in how it contributes to the core business: enabling things that would be otherwise tedious, difficult, or impossible; making slow things faster; extracting and storing information and making it available. The role of IT in the business should be defined, and the metrics should answer the question: How well is IT doing its job?
Whether or not the sysadmins are doing their job, it will show.
Otherwise, measuring one point of the organization has a tendency to skew work at that point toward a favorable measure. For example, measuring # of tickets closed within n hours tends to lead to all tickets being closed within n hours, regardless of problem status. (I have witnessed this as a customer. It's not nice.)
In other words, you get what you measure. Thus, if you get what you measure, you might just as well measure the thing you actually want, causing the work to skew in that direction...
I read the linked patent application, and I'm not very fond of the idea.
While driving, I need the following information:
A good view of surrounding traffic, assisted with mirrors where necessary.
Indication of conditions that require my attention in the near future (e.g. directional indicator is on, high beams on, handbrake engaged, fuel is low, oil pressure has suddenly dropped...), i.e. the usual warning lights, plus fuel and temp gauges.
Knowledge of my current speed, i.e. speedometer, to stay within posted limits.
That's all. A tachometer is nice to have to optimize performance and economy, but not a necessity.
What I watch while driving, in order of frequency:
The road in front.
The mirrors.
Speedometer + tach every now and then.
The rest of the instrument cluster every now and then, to check fuel level. Any warning lights will be noticed at this time, or while checking the speed.
My car is old enough (1999 Ford Focus station wagon) that heating and A/C can be adjusted by touch (rotary knobs). Also, the radio has controls in the steering column, so it can be controlled without looking. I don't use a mobile phone or change CDs while driving.
If there's information being distributed about something blocking the road... well, that's why I have the RDS radio.
For me, any additional information in the field of view would only be clutter, especially if it's moving or changing shape. In my view, it's a benefit of the traditional instrument cluster, as well as a traditional HUD, that every display component has a fixed location which can be memorized. This memorization can go so far that one does not need to focus to the instrument cluster; when I see a blue light in the dashboard, I know it means my high beams are on.
Analog gauges don't require exact focus for an approximate reading, and the most frequent indicator lights are pretty soon memorized. I can see a benefit in a HUD that displays the speedometer + active warning lights information while driving, but not in one that has moving or shifting elements (which only take the driver's attention off the road), or one that would be used while parked (a conventional display would work better, as it doesn't depend on lighting conditions outside).

The post was followed by an ad for Windows Server 2003. Are the Slashdot ads word-targeted?
So, the real problem is that with WinXP, they finally managed to create a half-decent desktop OS, and now they find they can't repeat the act?
