Ahh now we're getting circular. We can make vaccines quicker if we have samples of live virus ready to go/grow.
It becomes a simple equation of how many more people will die due to delays in vaccine production, vs how much does it cost to keep it locked up, which frankly is probably pretty cheap, and really cheap when divided by X number of lives...
If a human life was only worth, say, $1000, then I'd say autoclave it and spend the security money on more profitable, traditional government responsibilities like molesting airport travelers or bailing out the management of corrupt banks. But luckily, in most places, for most cultures, life isn't that cheap, so its worthwhile to spend the dough to keep the stuff ready to quickly make vaccines.
...an outbreak that would start from where exactly? This logic seems a bit circular.
Not circular if you assume it'll be accidentally released by the other guys.
Also the general public naively thinks only two known storage means only two storage sites exist... How exactly do you know the French don't have one? Or some dude working on it in NYC in 1960 died in '61, and they're just now getting around to defrosting and replacing his research freezer? I've often wondered what happens if some dude who died on a glacier 1000 years ago gets defrosted, and someone downstream drinks the water... On a regular basis cemeteries are dug up and moved, and before a certain era they are stuffed full of plague victims, thats just how it is... And how long can a single SP virus be preserved? Nobody really knows, although some smart people have some good guesses...
Can't see how anyone besides the ultra-paranoid would see this as a problem, nukes pose a more significant and real threat than these stored samples...
Completely wrong.
Release one nuke, lose one city. Sucks to be that city, but in the grand scheme of things, no big deal. For example, no one really cares that we lost New Orleans unless they have/had friends and family there... On the other hand, release enough SP to infect just one person, we end up with worldwide uncontrollable epidemic, very very bad for every living human being.
Furthermore the venn diagram of people who are experts at military style guard duty and people who have nukes in the workplace has staggering overlap, virtually 100%. The venn diagram of people who are experts at military style guard duty and bio grad students has mighty little overlap. So the odds of loose cannon nukes is staggeringly lower than loose cannon SP.
From the summary, it sounds like the "language" is just a noun mapping. Very much like my 14.4 modem did in 1993 over a phone line, when it came to an agreement with the modem on the other side about what voltage and phase pattern corresponded to the bitstream 0001 vs 1010, in fact my modem sounds like a more complicated language because they implemented MNP4 / MNP5 error correction, admittedly that required a lot of help from the humans typing in the "right" dialer strings and of course the humans who wrote MNP4...
Might just be a bad summary of a summary of a summary of a summary, and the robots had developed interesting sentence structure and verb conjugations and direct and indirect objects, adjective and adverbs, similes and metaphors, better than your average youtube comment... Or maybe youtube comments are actually being written by these robots, hard to say.
Your THz electric signal is going to go everywhere except down the wire.
The other problem is there really is nothing useful to do with THz AC.
You can't really do anything "useful" with 60 Hz AC without rectifying it, or doing some AC motor stuff. I think it would take a rather large number of "poles" to make a three phase motor run off THz AC, and as you note, the inductance makes it unbuildable, so we won't be doing either the electric or the electronic thing.. leaving us with not much. Resistive heating?
X-10, Z-Wave and Insteon are all also equally incorrect in that they generally put the control at the point of the switch, instead of the fixture.
"Insteon", more or less a modernized competitor of X10 and friends, does three-way switch emulation by having remote switches remotely switch the switch that switches the load. Yeah, I know, confused the heck out of me the first time.
Putting the PoC at the switch is apparently necessary for 3way switches, or you need to extend the protocol to add a "toggle" function.
beginning of the demise of widespread use of Mono and other.NETiness in open source software
This seems to VERY incorrectly imply there once was, or currently is, widespread use of Mono and other.NETiness in open source software. Is it a yogi-ism to say its so widespread that nobody uses it anymore?
But why 24K? Is that some sort of cost of living in the US?
In Manhattan only $2K/month means living in a public park, or having about four roommates in a single room apartment. Depending on the roommates, that could be kinda hot... or not.
In more civilized areas, think rural America, $2K/month means living (literally) like landed gentry, with, I kid you not, some (part time, illegal) servants.
Thats going to be the big problem with any flat cost of living.
Then, the social engineering starts. You'll never get medical care at a $24K/yr job, so I guess big brother will have to.... etc etc etc until its just as bad or worse than now.
Umm, from a practical standpoint I think your plan, however appealing, is going to result in the exact opposite.
Not saying its a bad idea or plan, I kind of like it, but please don't advertise it as having a goal which will almost certainly be the direct opposite of the result.
Its going to be nearly impossible to separate work from fun... my "gaming pc" is pure enjoyment at a high tax, but my "server pc" is pure work, except little do you know I'm using it to host lan parties just for fun, or I'm having "fun" learning about LDAP / openafs / kerberos at home.... So what is the "enjoyment tax" on a Asus A8V motherboard anyway?
Is that "fresh meat" at subsistence tax? Some vegetarians would not find eating meat to be "enjoyment", especially not the drama queen ones. So it'll be politically motivated corruption of a different sort. Is birth control an "enjoyment" at high tax, or a "religious sacrament" at a low tax, or a medical prescription at no tax?
A flat tax will work but it must be honest. To be honest it means we cannot tax corporations. Every dollar a corporation pays in taxes comes from its customers, that means we pay those dollars.
Another dishonesty of corporate taxes is that I am legally entitled to approx one millionth the local electric company profits. In other words, I own stock and am paid a dividend. Yet for mysterious reasons, the corporation pays income taxes on my money AND I pay income taxes on my money... Double taxation.
We do not live in a free market society, the tax code distorts it. This explains why so few companies pay dividends and instead go for capital gains.
Paying off those who own homes isn't really a simplification, it's what the housing deduction does.
Actually no, it does nothing useful for them. The group it pays off is the homebuilders, developers, etc.
Look what happens when the govt provides $5000 untaxed child care benefit... I do not end up $5000 richer, or even my roughly 20% average tax rate richer. What happens by supply and demand is the prices rise to match the new supply of money. Inflation, basically. The daycare knows darn well I can afford to pay more, and I will have to. So as an industry the price rises to compensate.
Same thing with the mortgage interest tax deduction... I have $1500/month gross income to spend on housing, without a tax deduction I pay about $300 to the govt in taxes, and $1200 to the bank. With the deduction, I won't pay tax, so I can now send $1500 to the bank. An idiot would think that means I'll get a higher quality house, after all, I'm paying $1500 instead of $1200. However the way it really works, is as a member of the 90th percentile of income (guess?) that would imply I WILL be living in the exact same 90th percentile house... The only thing that varies is how much money the bank and previous owners get.
The other big fail, is the idea that the govt will not spend $300 if I don't give it to them now. All it means is I, or my kids, will have to give the govt $400 later to pay off bond holders instead of $300 now. So even more money goes to make the banks and top 1% even richer.
All the mortgage interest deduction does is make the rich richer and the poor poorer. Which is, of course, as designed.
Want to get the cheapskates really wound up? Suggest multiple PCs. Maybe its my weird luck but both my current and former employer have provided multiple machines per desk.
Typically the "secondary PCs" are devoted to stuff like mail reading, manual reading, doc reading, or maybe instead a permanent connection to the airgapped production network, etc.
The sysadmin types love having multiple machines... SSH into a client here, a server here, and have that box watch the logs. Suddenly 15 minute troubleshooting clickfests because solved in seconds... Also fun to connect one machine / monitor / keyboard to each server in the cluster while working load balancing problems. One machine connects to one router, the other to another router, then you debug ospf...
If you don't use microsoft stuff, the cost of deploying yet another Debian box is negligible.
You mess with BitCoin, no guys with guns, only a technological challenge.
The bit stream with the most MIPS behind it wins. So all you need to do is own 51% of the worlds computational infrastructure and you're golden. Otherwise "messing with it" is not going to work.
will require Internet service providers to offer a choice of four filtering options
First, horrible word choice, such a nice green eco-policy of filtering clean spring water into crystal clear bottled water, or filtering sewage before pouring it into the noble savage wilderness. Instead of what it really is, which is top down totalitarian thought-crime enforcement.
Second, how? From a technical standpoint, I'm thinking segregate by mac address into certain ip pools, which then are censored by customized BGP feeds? Coming from an ISP background, I'm momentarily mystified about how I'd do it. Of course the way they'll PROBABLY do it, is postal mail one of 4 CDROMs to each subscriber containing MS windows only, MSIE only, censorship and keylogging and govt reporting and govt backdoor software, hopefully leaving mac / i-device / linux users completely and utterly alone...
family, child, domestic or standard
Whats the difference? Its an interesting insight into turkish culture that they can market four different versions. Here the mainstream marketing model does not acknowledge its even theoretically possible to separate those four groups. At least here, its a doublespeak concept that family = child = standard, don't know that domestic is, but I'm guessing it would be some patriotic middle america theme as opposed to foreign like foreign cars which are bad, unlike all Chinese junk at a walmart which is good, or something vague like that.
The only real difference between FRAM and memristors, is FRAM has been licensing and shipping COTS product for over a decade, and memristors are a vaporware product from extremely deep pockets trying to bite a piece off that (admittedly very tiny) market by skating as close as possible to existing patents / copyrights / trademarks without actually being sued out of existence. Its kind of like asking what is the technical difference between a "turbo-" marketed product vs a "i-" marketed product.
Both are basically microscopic core memories. Magnetic field hysteresis, measure magnetic state by trying to force to a given state and seeing how much power it takes, none means its already that state and a bunch means it was the other state.
There are other theoretical uses for memristors. The killer is both devices are current mode devices, which means they'll almost certainly never be power-competitive with voltage mode devices. The other killer is they are not silicon, so that means scrap all the existing fabs and start over. Plus virtually everything out there is silicon based, so it'll be interesting seeing the hybrid devices. And the fourth killer is that memristor/fram technology is advancing, but mass produced silicon dram is also advancing, in fact for a decade or so has been advancing faster, making "modern core memory" ever less interesting.
On the other hand, depending on their temperature handling properties, a memristor based CPU that glows dull red with heat might be OK, don't know. I do know that off the shelf silicon for a variety of reasons doesn't "like" working above a couple hundred degrees, but memristors might not have the same limitations.

Over the planet's transit over the face of the star, from our angle, the light interacts with the atmosphere of the planet before passing through to be seen by our telescopes. The light is broken down into component frequencies to determine the chemicals present and their relative concentrations in the atmosphere. Some chemical signatures can be understood as the the result of natural processes, while others do not seem to occur without the influence of biological processes. We are looking for 'unnatural atmospheres' modified by exotic processes that cannot be readily explained under natural conditions.
So the TLDR version is we're watching for a sudden methane (etc) signature for an instant as the planet transits its star? Why watch for 24 hours, then, assuming the orbit has been well characterized?
I guess they are using a 24hr "block" of radio telescope time... but it was just funny reading it. Like they are going to study them for 24hrs for signs of intelligent life. As if it was their "day length period".
I thought the negative elevation angle aspect was even funnier, assuming the targets are distributed in the galactic plane. I'm guessing they will take multiple days to gather 24 hours total of data. Or, maybe we've gone thru the journalism filter, and we're gathering "one days observation" and the journalist though 24 hours sounded "more scientific".
I suppose they could be limiting themselves to stars "that never set" in other word declination > (scope latitude + reasonable beamwidth / sidelobes)
Want to have some fun with the media? Tell them about "anonymous" ftp two decades ago, then tell them about the "anonymous" FTP over email services circa 1991, that'll confuse the heck out of them.
We see stupid things people do resulting in problems at regular gas stations all the time, will it use full time attendants or will just rely on people being smart while fueling up?
H2 has two obvious advantages over gasoline:
1) Leaks go straight up. Light it on fire and you get an immense fireball.... 100 feet up and headed higher at about 50 MPH. I'd much rather be trapped in a H2 car on fire than a gasoline car on fire. I suppose underground / underbuilding parking facilities would have a much more negative opinion...
2) It doesn't soak into winter clothing and turn the operator into a human torch like gasoline will do.
The obvious disadvantage is its extremely high range flammability limits, but its not that much worse than gasoline.
