Unfortunately, the true revolutionary rifle is the one that can be reliably and inexpensively mass produced by the millions, the one that won't jam, and the one that can easily be understood, fixed, and used by even a small child.
As far as I know we haven't outsourced our UAV development, so back to the topic of the article about UAV's and lets try to compare what they have copied.
I remember a similar situation in sixth grade math class. A student aced the wrong form of the test, but the teacher didn't punish him. He got the grade he deserved.
It doesn't say much about the professor at all. It takes a lot of time to put together new homework assignments and tests every semester, and if someone takes the time to do that for you, why wouldn't you take advantage of it? Six hundred students means it has to be multiple choice, so it's unlikely a test written by the professor is going to be significantly more thought-provoking and in-depth. Time is money. Universities don't really care about your teaching (unless it's seriously deficient), but you can rest assured that someone will notice if your research isn't making the cut.

The parentheses indicate common usage, but the meaning seems perfectly clear to me in this context. It is more fun to feign ignorance though.
And speaking of feigning ignorance, I thought maybe we were going to delve in to the mind of Alberto Gonzalez when I first glanced at the summary. Now that would be a story. But then I remembered personally reading about and discussing this Albert Gonzalez on a previous occasion. What did we talk about? I didn't directly converse about Gonzalez. I believe it was a spokesperson that discussed him. When? I don't recall. I told you. I remember talking about the other Albert Gonzalez. We went back and clarified the difference between the two. I don't know the specific content of the conversation, but I remember that it was about Albert Gonzalez. I stand by what I said to the committee. I don't know exactly... Well, I don't have a record of everything that was said here. I'll have to find out and get back to you.
It probably struck a floating buoy somewhere in the North Pacific. I don't think ICBM tests typically involve strategic targets or armed nucular [sic] devices, so I wouldn't worry—we'll probably never know.
That explains it then! They must've just bumped the date button while setting their clocks back an hour this weekend. I just showed up an hour early for a meeting and felt dumb enough. I played it cool. But if I'd launched an ICBM ahead of schedule you can bet I'd deny it too.
But why not push it just a smidge farther out into the ocean and away from the second most populous city in the US? Or run the test at night? It's only news because it was caught on tape in broad daylight by a news helicopter.
Agreed, but hard to see how it's even sabre rattling. I thought we were marginally above such displays of hubris, if only because it's about as revolutionary as walking out into a field and firing a canon. The first submarine-launched ballistic missile was the Polaris A1 in 1960 with a range of 1000 nmi. The cat is out of the bag.
Nothing personal—just feeling hyperbolical tonight and you have to admit that it was kinda set up for a slam-dunk. But I'll do my best to resist fanning the flames in the future.
Hell? Aha! Get those blood-sucking money-grubbing high-frequency investors a bit of whiskey and they'll be right at home down there! Perhaps all those people that can be heard shouting, "See you in hell you sonsabitches!" will be right after all!
That was unfair and uncalled for. I know, I know. But it sure felt good to say.
Naïvely agreed. If they had only put a cap on frequencies from day one, this whole arms race could have been subverted, but with $141 billion being managed with high frequency trading, that seems quite impossible now. But I agree that there's no inherent value created by a market that rewards transactions that challenge the speed of light.
However, I recently learned that you can really lose out when you look at something and twist your face into a knot and start shouting about why it's completely worthless. I wrote a paper on limitations of a method and what can be attained; someone else used the limiting phenomenon in a new and innovative way (and made a lot of money).
And so I propose that we build a server farm at the true midpoint between New York, London, and Hong Kong. And so begins the Race to the Center of the Earth! Oh, and cooling might be an issue...
The traveller who has never before experienced an arctic summer, and
who has been accustomed to think of Siberia as a land of eternal snow
and ice, cannot help being astonished at the sudden and wonderful
development of animal and vegetable life throughout that country in
the month of June, and the rapidity of the transition from winter to
summer in the course of a few short weeks. In the early part of June
it is frequently possible to travel in 'the vicinity of Gizhiga upon
dog-sledges, while by the last of the same month the trees are all in
full leaf, primroses, cowslips, buttercups, valerian, cinquefoil, and
labrador tea, blossom everywhere upon the higher plains and river
banks, and the thermometer at noon frequently reaches 70 deg. Fahr. in the
shade. There is no spring, in the usual acceptation of the word, at
all. The disappearance of snow and the appearance of vegetation are
almost simultaneous; and although the tundras or moss steppes,
continue for some time to hold water like a saturated sponge, they
are covered with flowers and blossoming blueberry bushes, and show no
traces of the long, cold winter which has so recently ended.
Calculus of Variations! Seriously, it's a fascinating subject. See Brachistochrone. It also ties in closely with optimal control and such subjects. There are some fascinating, counterintuitive results. A professor described a researcher who had used this to calculate the optimal (in some sense) ascent trajectory for a jet aircraft after takeoff. For the specific case, it wasn't even a monotonic climb!
If the AC was modded troll for that, it's probably only because he said it so strongly. Lyapunov exponents describe divergence of dynamical systems and mean that it takes a dramatic increase in mesh density, solution quality, boundary conditions, etc. to extend the valid range of predictions even slightly. I don't know the current state of the art relative to fundamental physical limits, but I'd be surprised if you or me ever see significant improvements in next weeks forecast.
That's the same way you find novel solutions to PDE's! You take a general solution, evaluate it along some strange curve, then pretend it's the problem you intended to solve from the start! Find a physical problem it solves, publish, and repeat.
Even the paper's author agree that this is a "conceptually simple and possibly practical iterative solver." They rightly recognize that what works well on paper may not always prove useful in practice. So I think we should take the authors' own advice and wait for further research into this approach.
Agreed. Reminds me of what a professor said after talking for a while about optimal matrix-matrix multiplication. The current leader is O(n^2.376), but the constant in front is so large that it's not advantageous for anything our computers can handle. "But you can get quite a few papers out of it!"
So medium-term weather prediction
turns out to be merely a fiction.
It's just anyone's guess
if you ask how to dress
it will offer no useful restrictions.
Then it's not for you. Move along. I manage to get plenty of work done but don't use any of those features on my laptop on a regular basis. That's what our workstations are for. To be honest, I love the idea of a computer that doesn't have all that extra junk to cart around all day.
For God's sake! This much of a debate over what to call it? It's a computer. It has specs. It has a size. It has a price. Those parameters may or may not meet what you need/want/find convenient/can afford/want to pay. Call it whatever you want. It's just semantics!
I'd agree. I've been quite impressed with the durability of Apple laptops. My Powerbook G4 had extreme water damage in the first year and works great seven years later. The optical drive had to be replaced when I soaked the whole thing in some water, and the HD had to be replaced when it wore out. My current MacBook Pro is bent like a potato chip enough that people walk past and ask, "What the hell happened?" but the optical drive is the only non-functional part. Fell down the stairs and bent it over the edge of a step almost a year ago, and it's still going strong.
So you'd better believe I'm encouraged by the fact that the MBA has no hard disk and no optical drive! Maybe I'm even a little intrigued. It would actually fit my current needs surprisingly well.
Don't forget that all we're talking about here is photons created in mid-transit so that it would look like there's a galaxy there. Personally, I still think dinosaurs take the cake in the category of artifacts created 6000 years ago solely for our bemusement.

Of course you mean we haven't legally outsourced our UAV development to China.
