We Aren't the World: Why Americans Make Bad Study Subjects
It never ceases to amaze me how self-proclaimed "intellectuals"...
Modded 5. Oh well /. it's been a good run over 10 years. See ya in another life...
Senators Seek H-1B Cap That Can Reach 300,000
Captured them? As in, they were prisoner-of-war labour? Doesn't sound right.
One identifiable immigrant community that did, with no doubt, come to the US and contribute to the space program was the Arrow diaspora.
Ticking Arctic Carbon Bomb May Be Bigger Than Expected
Hello. This is Canada. We want Puerto Rico, and Disney World. And we want border agents on the border formerly known as the Canadian Border to all be girls wearing bikinis. Or we pull off the Big Tarp we got thrown over the permafrost. We call it the Big Tarp. It's a tarpolin^h^h^h^haulin. And it's big. It's very likely not all in my imagination. You want 5000 degrees in Nevada? I know what you're thinking. It's already 5000 degrees in Nevada. Ok fine. But riddle me this: why doesn't the New Jersey mob bury their work in Nunavut? I know right? Permafrost right? You want the NJM burning all that gas driving 5000 km each way just to intern^h the whacked? That's not very ecologically wise is it? Is this not in any way less than unclear? I though so. All replies through Santa's village, North Pole, Canada, H0H 0H0. Hosers.
Edit: This is the wife speaking. Or boys wearing thongs, but only nice ones like Jeff Goldbloom in The Fly, not Jeff Goldbloom in The Switch. Eww.
British Skylon Engine Passes Its Tests
In your basic gas turbine thermodynamic cycle, the Brayton Cycle, combustion takes place on incoming gas that has been compressed. That's what your compressor stage is for in a jet engine. In a ramjet the kinetic energy of the air is converted to pressure by a converging-diverging compression shock nozzle. (We notice Sabre has a ramjet-type compression inlet). The process is so fast its adiabatic (no heat goes in or out). The more compression you can get before combustion the higher the efficiency.
Adiabatic compression equals heating (ref. Charle's Law). At hypersonic speeds it gets so hot before you even start combustion the materials freak out. You can't make it much hotter by burning your fuel. Low efficiency.
By cooling the air you can get enough compression to yield a decent efficiency. It's not a Brayton Cycle any more though because that features adiabatic compression by definition. Sabre is all about removing heat in the compression stage.
Why Coding At Fifty May Be Nifty
May I paraphrase?: "That silly stuff engineers do? Fun and easy compared to the really hard important grown-up job us executives do."
Air Force Lab Test Out "Aircraft Surfing" Technique To Save Fuel
vorticity is conserved. The flow over a wing is a rotation superimposed on a translation which results in the slower flow underneath and faster on top.The rotation, usually called circulation, embodies a certain value of vorticity which can't disappear. Where it goes is it turns 90 deg at the tip and trails back behind the a/c all the way to the tarmac (vortexes have to terminate at a boundary...the ground).
If the wing is longer, for constant lift, the circulation reduces because a wider swath of air is turned downward so to give the same z-direction momentum flux the amount of "turning" is less.
By flying tip-to-tip, a/c effectively create a longer wing. Physically of course it isn't one wing but happily the highly coherent trailing vortices can be coupled by overlapping them, they rotate in opposite directions so tend to cancel each other out.
(The reason "bees shouldn't be able to fly" is that it appears to take too much energy to create the circulation around their wings every flap. It takes energy to "spin up" the air. How they do it is they slap their wings together at the top, when they separate they shed a vortex back over their wings which gets the circulation going. Not obvious.

Realistically, how? The notion that an idea can be property is firmly ensconced in the Zeitgeist, and billions of dollars of wealth depend on it staying that way.
Who or what has the kind of realpolitik oomph to go up against that? I don't see it.
Rare Form of Autism Could Be Curable With Protein Supplements
I have a metaphorical way of making sense of autistic behaviors. Let's say the brain has some kind of sensory input buffer. Defects in that buffer might lead the brain to be overstimulated with sensory input and become preoccupied with them. The other thing the buffer might do...and this is where it gets more metaphorical and maybe less factual...is serve as a feedback path for brain-generated inputs, to sort of test things. Like when someone says "Imagine what it feels like when..." or even when you just think about real experiences you had. I think of dreams as maybe working like that too: brain generated inputs get cycled back through the buffer to serve as virtual experiences for...whatever dreams are for. That way of thinking about it leads to a way of understanding stimming behaviours: they can be thought of as dream-related movement that we don't do during sleep dreams because of sleep paralysis.
I find having a (metaphorical and maybe not correct) mechanistic way of understanding autistic bahaviours makes it a lot easier to deal with them.
Ask Slashdot: Protecting Data From a Carrington Event?
How would optical be wiped by e/m radiation? As for magnetic, as long as there is no physical damage taking place (I'm no Carrington event specialist, but it doesn't seem as if high energy particles do the damage, just warpage of Earth's magnetic field (someone can correct me if I'm wrong)) wouldn't any old Faraday cage do? I wouldn't be surprised if the metal drawers in safety deposit boxes would be sufficient.
Bad Software Runs the World
I have used this program my entire career. For the last 20 years (since MSC bought PDA), it has not changed apart from the odd user-generated macro getting included in. The windowing interface has had the same bugs (e.g. scroll bars that are 1 pixel high) since I was a wee lad. Half the stuff in it that isn't used regularly doesn't work, never has, never will and yet it is the standard for FEM pre/post in aerospace. Staring at this broken-ass POS year after year has filled me with ennui.
May there be a special circle in hell just for MacNeil-Schwendler.
Thank you. That is all.
Bad Software Runs the World
That is because corporate infrastructure software does not generate revenue...
Hi. Corporate infrastructure supports the creation of whatever the corporation sells. Thus, creates wealth.
Where any specific bit of the enterprise fits in the revenue generating chain is an arbitrary organizational decision. Ultimately the entire entity is there to give the sales force something to sell and the ability to accept purchases and support customers.
In other words, the pointy end of the stick is useless without the rest of the stick. It's just prick lying on the forest floor under a pile of bear poo.

Are Engineers Natural Libertarians Or Technocrats?
May I interrupt the "engineers are this or that" war to ask one thing? Could we get a definition of the word "engineer" for the purposes of hostilities?
Most places I know (with the exception of the province of Quebec) allow all characters no matter how unbalanced to call themselves engineers. So I guess we need to control for the population of sociopaths who call themselves engineers because calling themselves doctors would be illegal. And for the companies who call some guy named Charlie wielding a toilet plunger an engineer because... oh jeez that's depressing.
Also, I'd love to see citations when someone makes a "these people are like that"-type statement.
How Anonymous is AC
For certain reasons I logged off and made a post as an AC. At the moment I have some mod points.
When I logged back in and returned to the discussion, I was able to mod all posts in that discussion except the post that I created as an AC.
How does /. know it was me that created that AC post? IP? Some kind of cookie magic?
What does the anonymous in AC exactly mean?
Puzzling. I wrote this post about a possible career alternative for gear-heads like I assume most of us around here are. In the context of outsourcing.
Frankly, with a little work (ok a lot of work), most young people with aptitude in math & physics can get a career with doctor-like compensation. Not one mod point. I don't care about karma or mods, but it puzzles me that the discussion would centre around fair/unfair and incompetent management.
I don't know. I thought people would think it's pretty cool to learn there's red-hot demand (which seems to be sustained) for certain geek-types and I even give detailed instructions how to get into it.
Puzzling. Oh well maybe the right people didn't see the post, which would be too bad.
Troll Mods are Annoying
Back in '82 or so, I spent my time working up a Master's thesis at the U of T MechEng building. Every so often, perhaps once every two months, I'd be waylayed in the corridor by a complete stranger who had obviously wandered in off the street. Invariably, this stranger would be looking for a professor to legitimize his perpetual-motion/free-energy device/idea/theory.
That was 25 years ago. How many such would-be revolutionaries have come and gone in the years since? Hundreds. How many at all the universities in all the world? Thousands.
None of them have been right. All of them have been wrong. Why? Because their ideas violate the basic laws of the universe that we have learned through the application of the scientific method.
To suppose that the genius embodied in the known laws of physics can be swept aside by double talk that at it's core is nothing more than the verbal manifestation of a glib sense of dismissive entitlement is breathtaking. That Slashdot panders to this ignorance places this community on exactly the same level as creation science. Meanwhile, the editors cower behind the juvenile delusion that powers Fox News; that every dissenting viewpoint, no matter how insane, deserves equal time.
Perpetual motion is not news, for nerds or anyone else. It is not stuff that matters. It may, however, be interesting to the uniformed uneducated train-spotting passive-aggressive conspiracy lunatics that make up the vast majority of Slashdots newly targeted advertising demographic.
I'm to spend my time thinking of quality posts to cast before such swine, why exactly? I'm to be troll-censored by a thirteen year-old, why exactly?
