My read of the Lightning protocol spec is that the meaning isn't obscured. An LN invoice is authenticated, but it isn't encrypted. I may be misinterpreting this spec, which I just found 5 minutes ago and kind of skimmed, but it makes sense: this is a request for a transaction on a fully public blockchain, so there can't really be anything private there.
I can't tell if they're using testnet bitcoins in this, but that would be one way to avoid any commerce happening for the purposes of this demo. It does kind of put a damper on the practical applications, though.
Professional software isn't immune to this. I've had many many bugs I file and features I request at work languish for an inordinately long time because "we're in the middle of a release push" or "the other project is behind schedule so all resources are behind that" or even organizational infighting.
Having maintained several similar phone systems: this does have the advantage that when an inbound (e.g. client) call forwards to the cellphone of someone in the field, they get the number of the actual client instead of just the main trunk number or their own DID.
Chess is a perfect knowledge game. Integrating a view of the world good enough to play by isn't part of the strategy because you can already see everything. DotA is... not. If your strategy for dealing with not being able to see the entire field of play at once is "We use an API to see the entire field of play at once anyway," you're not playing the same game as someone with limited perceptual bandwidth.
I think you slipped a few orders of magnitude there. I get 17 days for "the initial part." Intuitively, your numbers don't make sense: there is no way that satellite has 100Gbps downlink, or even anywhere in that neighborhood, so the time to download the dataset over a 100Gbps link should not be an appreciable fraction of the total 46-year program duration.
That said, sneakernet may be a better approach here.
The Alaska Permanent fund also does this on a larger scale, although the amounts of money involved there are probably not enough to make a living except in the Alaskan backcountry, which has limited (but not no) use for money. The Alaska fund is also funded by a severance tax on oil, not a progressive income tax, which seems far less likely to lead to unsustainable fiscal situations or perverse incentives.
The auto industry has strict standards (ISO 26262) for exactly this already, for non-autonomous cars. The safety requirements aren't really any different for level 5 autonomous driving than they are for ABS or steer-by-wire (i.e. they must be "designed to ASIL D," i.e. a failure in any of these systems probably results in an unrecoverable, potentially fatal crash), except that the autonomous driving system is far more complicated.
I live in Central Texas, and all our recent toll roads are full-speed for everyone. They've even shut down manual toll booths on roads that used to have them, because the license plate readers are too good to need them. If your plates are registered with the toll authority like mine are, your credit card is billed and you don't have to think about it, and if your plates aren't registered you get a bill in the mail.
There is a service fee for paying the bill by mail (as opposed to receiving the bill in the mail and paying it online) which is kind of eeeeh, but then handling paper checks does cost money.
> Gas turbines burn natural gas directly in turbines that generate electricity.
Not to take away from your point, but modern combined-cycle gas plants have both a direct gas-fired turbine (running on the Brayton cycle) and a steam-fired turbine (running on the Rankine cycle) that recycles the waste heat from the post-turbine exhaust gases. Physical limits prevent a single heat engine from extracting more than a certain amount of energy in one step, so a combined-cycle plant combines the two cycles for an efficiency increase.
We do have chip fabs in the West. Intel has its main research fab in Oregon and production fabs in Oregon, Arizona, and New Mexico. (Also in China.)
That said, Intel is more or less the only one doinng high-speed digital processes in the US: TSMC and Samsung are foreign-owned and mostly fab in their home countries (and, again, to some extent in mainland China.)
And yes: semiconductors do go through a lot of toxic dopants and etching chemicals.
Yes and no. The 2x4s used in standard residential framing burn quite readily. Larger timbers form a protective char, which, as long as it remains on the wood, protects the inner core from fire. If the timber has been specced correctly, the char does not penetrate deeply enough to compromise the structure for some time.
Steel, meanwhile, is an excellent heat conductor and therefore will start to sag as soon as the outer edge of the steel has reached a temperature that will cause sag.
You'd think that, but thousands of people still forget to unload their handguns from their carry-on baggage every year[1]. Those cost on the same order as a cellphone and failure to remove them can result in jail time, not just missing a flight.
Sure, it created high speed rail, but it also seized a bunch of landowners' land. In some moral systems, this is completely unforgivable, regardless of any benefit derived.
If you're in the open in an electrical storm with tornadoes, you are already having a bad day. If the sirens are going off, it means there's known to be a tornado near you already, so the lightning is kind of a secondary concern at that point.
That may work for you, but if I spend time customizing my setup (especially window manager key bindings), I am able to get work done much faster than had I not.
Generally the muzzle discipline (Rule 2) is relaxed only after partial disassembly. At that point, it's less a firearm and more two halves of a firearm.
Chip production is very similar, though the prices I usually hear quoted for the first unit (I am a student, so these may be out of date) are usually somewhere in the mid-hundreds of thousands. And the incremental cost (the cost of chip #2) is as low as pennies, depending on how big the chip is.
The fact that com, gov, edu, and net do not have A records (that is, they do not point to a specific host) does not mean there is a technical reason they cannot have A records.

I think they're using JS8Call. cf. this article about prior work in the space and the screenshot on the JS8Call software page.

I think you went the wrong way. 23MJ/m^3 is 23kJ/L.

People are indeed studying this.

90% of everything is crap, so finding those other 10% of things isn't easy.

Positive outcomes are in the eye of the beholder.
But what do Klingons look like, anyway? There are already several good answers.

The entire economy is a game of the-man-behind-the-curtain.
So much so that the phrase "man-behind-the-curtain" comes to us from The Wizard of Oz, a work of economic satire.

That's a good reason why they shouldn't resolve. I think I had misinterpreted your previous comments to mean that they couldn't resolve.

Or just cat5. This is what PoE is designed to do.
