You have not lived until you've seen the early-90s copy of The Absolute Sound which explained why a copy of a music CD sounded better than the original on the same equipment.

Only if all the choices actually work. I've hit my lifetime tolerance quota for software that says in effect "To make this work, you have to pick the right one out of 100 configuration options four times in a row, exactly like opening a safe except you have to get each piece of the combination from old message board posts".

Friend of mine consulted at the Vatican and reported just what everyone else does: until you've seen that, you have no clue what "bureaucracy" can mean.
Unless you're an expert crypto protocol developer and you're not going to deploy it to the field until it's had several years of peer review.
That business with the timestamp? Offhand I'd say the bank was trying to do the right thing by preventing replay attacks. But using a timestamp? I'm having trouble keeping up with just the obvious attacks against that, let alone the attacks that a seasoned crypto developer would find.
If you ever need to do what the bank tried to do, find something already written and battle tested, make sure its assumptions and security properties line up with what you need(*), and use that instead of repeating the last fifty years of protocol design mistakes.
(*) Then you'll find that they assume trusted endpoints, which is something worth reflecting on.
>The example of squeaky floors is something that is directly addressed in the article. The nails have a twist towards the head of the nail to make them less likely to back out. It works under normal conditions
That wasn't new in itself. There are already flooring nails that fit into a nailgun but have a slight twist to give them some screw-like resistance to being pulled out. There's even a variety that has a drop of solid glue which melts under the friction heat of being driven in and then resolidifies to hold the nail. Ring shank nails are also an existing technology.
I did a lot of research on seismic retrofitting, and for that particular purpose nails are better than screws. The greater shear strength means they can flex before they break. The flex means that the plywood shear wall they're holding to the framing can scrape against the framing on each cycle. This friction dissipates energy like a shock absorber does and damps the oscillations. Buildings in general are horribly underdamped.
One interesting ramification is that you need to limit the number of nails, or you get a structure so rigid that it transmits energy instead of turning it into heat. "Nailing schedules" are a big thing in seismic engineering.
This is an example of R&D that is mostly D, a patient search through design space rather than a flash of inspiration. It's worth encouraging via the patent system. Flashes of inspiration are so gloriously fun that people will do them anyway.
Oh, and what do I do for my house? I just upgraded the railing for my deck and its stairs. The balusters are each attached with a pair of bolts. It was so time-consuming that I understand why people still use nails, but I feel safe leaning against it.
Shelf space and displays are frequently bought by the manufacturer. Ad space is often the result of co-op advertising. What you're seeing might be a vote of no confidence by the retailers, but might also be a Microsoft failure to pay for access to the channel.

That should have been phrased to explain that it took turnover into account. Otherwise anyone capable of arithmetic will read the rest of the article looking for clues about how half-time employees were filing overtime claims.
It's not "market value" if the buyers are being subsidized. Not only does the mortgage interest deduction push up demand, it most rewards the richest buyers.

We've all seen it happen. The microwave oven goes on, the Wifi network stops.
The microwave is shielded, but shielding isn't a binary thing. It's there to cut the leakage to legal levels at a tolerable price.
Since it can shut down a WiFi network, you know that the leakage from the microwave is about as strong as the wireless signal.
Data backs up the thought experiment: ballpark numbers people toss around for microwave oven shielding are around 35 dB, which cuts a kilowatt down to about a quarter of a watt.
If they accept ovens they should accept network gear. If they ban network gear they should rip out their home microwaves.
In Soviet Britain, you go to school to get more ignorant.
The inverse square law applies to open space with nothing to absorb radio waves. Buildings are full of materials that absorb radio, which is why your cell phone is such a hit or miss thing indoors.
That may well be the way you want it to work, but check out the 2001-2002 report of the Saskatchewan Human Rights Commission and look for "Hugh Owens". He faced legal action for buying a newspaper ad full of Bible verses. He went fishing in the bilges of the Bible for some nasty anti-homosexual verses, compiled a list and published them.
His case had an interesting course through the system that didn't really fit the narrative that the hate groups promulgated, which was "they've declared the Bible to be illegal hate speech". It started with him being ordered to pay CDN$1500 and went through some appeals.
Point being, it was not incitement to criminal activity, and if you were correct then the government would not have acted.
Everyone knows that you can't make perfect simultaneous measurements of position and momentum. There's another such measurement pair, energy and time.
You need time to make a completely accurate energy measurement. At very short time scales, energy levels can be uncertain enough to be large enough to create particles.
These are called "virtual particles", even though they're as real as any other sort, simply confined to a temporary quantum fluctuation.
If you think this sounds like hocus-pocus, you have a healthy skepticism, but when you do the math for particle interactions and include the virtual particles, it all works.
They're appearing and disappearing constantly, and sometimes people do call it a soup.
Remember when the digital photos from Abu Ghraib came out, and the Pentagon immediately swung into action to prevent any repetition? By banning digital cameras?
The school is simply teaching the kids an important real life lesson about what happens to whistleblowers.
I just want to hear an explanation of how they run a thermionic system backwards to produce cooling. And how a ceramic plate (thermal insulator) "makes heat distribution uniform" and "takes the heat away".
Either the guy was misquoted even worse than usual for the business press or the ideas are completely scrambled.
>power densities necessary to be a commercial power source (several GW).
Utilities don't really like buying generating capacity in GW lumps. Their idea of ideal commercial power would probably be in the 30-300 MW range and quick to build.

It's traditional to have the lights low for that. Also to soft-focus things intended to be erotic.

A man could live for years without being handed a straight line like that one.
Wood is a versatile substance that meets several needs simultaneously.
As Dave Barry pointed out, wood is the only known construction material which both rots *and* burns.

>A regular thermal power station has approx the same heat to energy conversion ratio.
Very approximately. Ballpark thermal efficiency for a coal plant is 40%, some higher and some even lower. This guy's claiming 20-30%.
I hate installation procedures that have the attitude "guess wrong, and we'll make your system unbootable, and no you can't get a hint".
