Insightful, possibly, from a "what would your mother say" point of view, but not necessarily form a legal standpoint.
Common practice can become a part of law through judicial rulings, and in this case there is arguably a good reason for this database (seeing as how a database suh as this does not exist in the public realm, nor is there any real impetus to create one). Google would like the law to be interpreted for its intent, not necessarily the letter, and the believe they might have some footing.
Really, it's a non-issue, except there's gazillions of dollars of corporations involved, and those gazillions of dollars are usually fighting with one another.
It's all about face time with the decision makers. You get face time, you get promoted. You don't get face time, you don't exist. Managers don't promote people they don't know about. If the company is doing well becuase there are a bunch of good workers in cubes working 7 to 5, there will always be a couple of personable, social [smokers/drinkers] that end up hanging with a few folks in management after hours (you know, while you're tending the family). Among the idle chit-chat, they're going to talk about what's going on in the office, and I promise that they're not going to relate that they find the coolest videos on youtube every morning. They'll say what great things are happening, and what they're doing, and mention how well they get along with a bunch of the staff. So who's going to get a promotion? The guy in the cube that the boss has never seen except from a podium in 100 person staff meetings, or the one that that he has taked with and, by the brownnoser's admission, clearly knows whats going on in the office and knows the crew?
1.5x the annual salary of the employee to be replaced. That's an average number for workforce losses. Figure $80-100k per IT person to be replaced, on average.
- training the rest of the workforce?
Basic Linux skills - 1 "extra" day over a version upgrade, presuming they're not going to be actually proficient. Add 2-3 hours of complaining, and an hour lost to scheduling. Opportunity cost (billable hours lost) for an office gnome: $50/hr*12 hours = $600
- lost productivity due to the above?
Ooh, that's a hard one. I can see a week's lost effort in the first two years of switchover, on average. Simple tasks aren't a biggie, but stump a low/mid-level exec working on a sequential-time critical app and he'll sit around useless for 2 days on a single issue. 40*50 = $2000.
This, of course, ignores the custom in-house apps that might need to be rebuilt to work with Linux that would have otherwise been backward compatible with Vista. The subsequent debugging downtime and lost productivity could double or triple the total time loss and training numbers.
It really is case specific, but you're likely to lose money in this comparison. The other thing is you will likley decrease morale. It is probably assumed that you'll skip the hardware upgrade for the more efficient system, but that means your employees are going to be stuck with that "old" machine for the next 2-3 years. Also, they'll have to change to a "different computer system" instead of getting the "upgrade" that all their cronies at other businesses are getting. They will feel like they've been shafted, even if they eventually learn to like the system. That down-tick in morale should not be underestimated.
Not really - set out five candy machines with top selling candies at a two dollars a piece. Fill a swimming-pool sized area with plastic peanuts and put the same candies in there, along with a bunch of candy-wrappered rocks. You'll get a good number of swimmers,a dn they'll come back time and again.
Set out the same five candy machines with top selling candies at a 5 cents a piece. Fill that swimming-pool again. You'll get a few first-timers, but most will come back and pay the five cents thereafter. There will always be a hardcore few with nothing else to do but filter through the peanuts and rocks in hopes of getting the type of candy they like. Most will buy your candy.
I know I shouldn't feed the trolls, but here goes anyway:
No, John Stewart is, imho, left of center, but not by much*. Nonetheless, he's just as quick to poke fun at the Democrats. His show is popular because he makes fun of people, and making fun of people is always humorous - especially to the 20-40 demographic. He has an expanded following becuase he tends to poke fun at people who shouldn't be targets, but make themselves so through their poorly thought out actions. Politicians happen to be the perfect targets.
*Stewart is not far left. Simply disagreeing with Rush and saying that Ann Coulter is a bitch does not make one far left. Blowing up a lot full of hummers to "save the earth"...that's far left.
I want the cellphone in the watch with a bluetooth headset that is the size of a high-end hearing aid and takes voice communication via vibrational coupling.
Of course, then I'd have to get a pda, which I was hoping to drop when I get my new whiz-bang everything-under-the-sun phone next spring.
That's true, but my (poor) memory seems to recall that no thermodynamic cycle can exceed the Carnot efficiency - it is the theoretical limit. A turbine does have a cycle, though I can't remember the name offhand - it's been almost two decades, and I don't do any thermo in my line of work....Okay, google is my friend. The answer is the Brayton cycle, and the effeciency appears to be 1-T1/T2, which is identical to the effiency of the Carnot cycle, presuming theoretical gasses and adiabatic conditions (neither of which exist in turbines). So the answer is still about 6000 Kelvin (not celcius, and extra , which is a good bit above the melting point of most materials. From Wikipaedia: The chemical element with the highest melting point is tungsten, at 3695 K (3422 C, 6192 F). The often-cited carbon does not melt at ambient pressure but sublimates at about 4000 K; a liquid phase only exists above pressures of 10 MPa and estimated 4300-4700 K. Tantalum hafnium carbide (Ta4HfC5) is a refractory compound with a very high melting point of 4488 K (4215 C, 7619 F) I'm banking that this isn't running at 6000K.
No, they just reside outside in their own enclosure, just like anormal backup. A little wart on your house next to the electrical entrance. Of course, I didn't see what either ran on (maybe I missed it) - if it's hydrogen then you're golden, if a little soggy over an extended period. High carbon HCs, then you're not so good.
That's what it would take for a carnot cycle to be 95% efficient (give or take) with a room temperature heat sink. Is it really burning this hot, or is the article full of shit? (or is my thermo just that rusty?)
Try 100 or 200 for a house with low power demand and a segregated backup panel for limited circuits. I'd need 960 of these to fully backup my house (all electric). Heck, you need twenty just to fire up the old lady's hair drier.
At 95% efficiency (a dubious claim, imho, given that the cold sink temp is presumably room temp), it would be a good source for constant charging and potential peaking current. You'd need a good number, though, at roughly 8 to the horsepower.
I think the future might be in portable power and backup devices - having a refillable, continuous 7-15kW power supply in a breadbox. With the right gear ratios, it could put out sinusoidal 60hz power for AC backup, though synchronizing the signals and preventing drift across the array would be a task in itself.
Yes, but that's very hard - even moreso for technical people. We (and I count myself as one) do not have the same desires as the average consumer. Not even close. If you are enthusiastic about anything and think you've got a lock on what the public thinks based on your likes/dislikes, you're either (a) amazingly gifted or (b) totally deluded. Your chance of falling into category (a) are probably less than 1 in 10,000.
Never underestimate how apathetic your customers are to the minutiae of your product or service. Ease of use will trump techical superiority in almost all cases.
You are correct, but saying that knowing what customers want being the good idea is like saying that all you have to do to win the lottery is to pick the correct numbers. As few numbers as there are, it's damned hard to do so, and looking at last weeks numbers doesn't mean squat for what will win this week.
In a pseudo reply to the children here, an architect is probably the right place to start, as ggod ones will have interior designers on staff who are used to working with the layout portion of offices.
It probably has more to do with students ability to budget time and allow for the proper schedule to write a paper than attention. There's also the typical slacker that just looks for the minimum effort path. Of course, as they expect to be far younger and hipper than you, you wouldn't even think to look at a place like Wikipedia for information so that source is perfect for plagiarism.
Outside of academia, it is generally accepted truth that original research is a foolish waste of time (okay, maybe in print media its okay). Getting things done (i.e. a report written) in the minimum amount of time is the measure of one's financial worth to a company. If we want to produce real crack business grads, we should teach them how to plagiarize without getting caught. Of course, if you want them to be honest, upstanding citizens...well, by the time they make it to college their parents have probably already ruined them for that.
There are some cable providers who will not give you cable cards - you have to allow them to install them in your equipment. Many TiVo S3 users are running into problems over this. Hopefully it will get better, but I'm not going to hold my breath.
Conponent out shouldn't have been too hard. I've got a Unicorn media box that does it. HDMI (unencrypted video+audio) would have been a nice touch. HDTV component in would have been snazzy but killer for the cost - there's just too much data to suck in and recode. QAM might have been nice, but it seems that many cable systems are going away from in-the-clear, analog broadcasts. Smart card...well, that's just a pipe dream - the consortium that controls the hardware IP wouldn't even let TiVo have T2Go or box-to-box transfers on the same intranet; they'd never let an open box have that.
You're mixing up angular velocity with tangential velocity. Think of angular rate instead (radians per second). At a given distance from the origin, the tangential velocity (in m/s or km/s) will be proportional to the radius for a given angular rate.
The key is that angular rate means squat when it comes to calculating the work required. What matters is tangential velocity - and every time you double your distance from the earth's center, your tangential velocity must also double if you want to "hover", or maintain a constant angular rate. Since GEO is at 37km altitude (45km radius cm to cm), you'd need to be going 45/6.8 x tangential velocity at the ground - 232m/s if I did the math right - or 1.5km/sec. You need to pick up that 1.25km/s, plus your gravitational potential, to stay in GEO.
Imagine having to suffer through another season of Al Groh's abyssmal football team. I say he got out just in time. It's only a shame that he took so few classes in the fall that he might have had time to see the 'hoos limp into a bottom tier bowl game.
To be honest, the word I've heard is that UVa is (relatively) tough to get into, but once you're in, they pretty much stamp your card for showing up. I had a cousin or two that graduated in Honors General Studies (they call them Eccol's Scholars, or some such). One became a housewife, one worked in marketing at a bank which ended up going under. The latter traveled the world for a couple months, then came back to the states and decided to pursue a MD. That's probably the best use of that program - a stepping stone for another (useful) degree. I won't argue that there are smart kids there (both of my cousins are very smart, the former is close to her PhD in Clinical Psych now, and the latter is in residency), but there's a little less practicle work going on than I'd like to pay for.

You're right, it's really more a parimutuel betting scheme. ;-)
True, but good sinusiodal power is expensive to create, and you'll have to go AC-DC-AC, since this is a rotor which will produce a non-dc output.
...The Aristocrat!
(Oh, admit it - you knew the punchline before you read it)
So selling short in the closing days of an option is (a) not based on chance or (b) has some statistical background?

Or, more interestingly, how much resistance will you get when trying to rotate it cross-axis.
Also, at 500k rpm, what kind of damage will it do if/when it fails.
