Ah! A State's Right's sort of person who wants to go back to the thirteen colonies instead of the nasty Union where people in other States get to have a say in your affairs - I should have known.

to what degree it was satire is debatable

With respect, the strings between husbands and wives so that they can find their way back when drunk is a pretty enormous fucking clue!

I tried being polite but you are not only a fucking idiot but one that wants to throw away what George Washington gave you.

Well.... any long-term confined high temperature isotropic quasi-neutral maxwellian plasma has to be large. Of course, if you start changing those requirements, you start changing the required size for your reactor. It's not theoretically impossible to have a viable fusion power plant that does not follow those constraints; the challenge is achieving it without either imposing a new, even more onerous series of challenges on yourself. Drop the concept of long-term confinement (for example, inertial confinement) and you find yourself with incredibly extreme compression challenges and having to deal with blowing your target apart on every fire. Don't use a quasi-neutral plasma and the plasma density drops by orders of magnitude, meaning your fusion rate drops so low that even little losses in the system will kill the concept. Don't use a maxwellian plasma and you have to find a way to hold the plasma away from thermalization without wasting more energy than the fusion yield, which is impossible by simply applying energy to part or all of the plasma - it's only even theoretically possible if you accelerate only the highest energy ions, creating a plasma only slightly skewed from a thermal distribution, and even if you have such a means, it's not easy. And so forth. You can remove constraints on fusion but then you get hit by others.

Unlike many here, I don't see it as an impossible problem simply because it hasn't been made economical yet despite decades of work. Because in those decades of work there's been orders of magnitude improvement, and I don't see those improvements just suddenly ceasing across every line of research. But no question, this is a Difficult Problem(TM).

We used to use unidirectional ethernet cables. Basically the TX wires clipped out on the receiving end to the less secure network. You do need ethernet cards you can set to accept a link without having a full handshake going.

But it allowed us to set up the SCADA network to take the data stream we needed to get to the collection and reporting pc and UDP broadcast it. then the PC that can only receive set up to listen for and receive it, works great and is 100% hacker proof as hackers have yet to write code that can cause copper to grow back in a CAT-5e cable.

Now if we could keep the N00b SCADA programmers from bringing in their crap-tastic home laptops for programming changes and becoming the largest infection vector.

I suggest you read "Utopia" by Thomas More (it's online in English and not very long). One of the bits to show it was deliberate satire was that the laws were so simple that anybody could understand them yet completely fair and without loopholes. Thomas More was a lawyer by trade.
So seen as a ridiculous joke in 1516 - is life so much more simple now that it's no longer ridiculous?
While some simplification is a good idea I don't think we can dumb it down enough to get rid of the lawyers without risking some grave injustices (see King John and why we ended up with Magna Carta to rein him in for example).

Travelling down that road can mean that you have to be a member of lobby group X before your devices are allowed, and that group will have a cost of entry designed to squeeze out linux users, bsd users, radio hobby types and anyone else who doe not have a commercial stake. See the broadcasting sector for examples.

Ok, so many things wrong here:
1), In Hawaii, that 1-2 battery pack is enough to power their homes at nighttime. The reason is that they pretty much have no HVAC. They are currently prohibited from adding Solar and then selling to back to the utility. However, if they add batteries for the home, and have the car, then they do NOT need the local utility. And with .38/KWH, these are MUCH cheaper to run for home.
2) nearly all homes in America do NOT need to have increased power lines to handle an electric car. The reason is that nearly all of our homes have 200 amps and can handle a dryer AND an electric oven. Even at the same time.
For charging an EV at home, all you need is a 240 V/40 A, just like on Dryers, and then have the car autocharge after 1 AM.

What does not make sense is why so many ppl hate Tesla and scream that anybody who sees economic value in it, to be a fanbois.

So, in other words, these models were specifically made for and distributed by an ISP, and were not off-the-shelf models. The backdoors were there for the ISP managers.

Well, I trust my ISPs router ... well, not at all, actually.

Because I assume my ISP is either incompetent or dishonest, I don't really care which, I simply don't trust them. And I sure as fuck don't trust them with access to my actual network. I want a layer of security between me and their shit, because I assume their stuff is trivially hacked.

My wife and I each have our offices set up where our own router is getting DHCP from the ISPs router, and then firewalling everything from it. We each have our own locked down wifi, and entirely separate networks. I'm pondering a third router to provide the guest wifi.

Other than disabling the ISPs wifi and using our own, I wouldn't even know the SSID or the password for the ISPs crap. I assume they haven't turned it on without asking, but I never check -- come to think of it, I'd have to find out how.

My parents and my in-laws have routers we've bought them to sit behind the crap the ISP provides. Because I know for a fact that in both cases the ISP provides a router with default wifi SSID and passwords which are published in the docs they give you.

Because it's printed in the "how to" for every damned subscriber, and you can't change it, you can pretty much imagine that if you find an SSID of the right name you can connect to it, and probably have management access to it.

For 99% of network users out there, these vulnerabilities are of no practical concern.

But the problem is so many households trust that the wide open, back doored, well known remote-admin credentialed, shitty routers they've been provided with give them any form of security.

Which means for the overwhelming majority of home users who aren't tech savvy and paranoid, these vulnerabilities are absolutely of practical concern ... because their PCs are directly plugged into the ISPs router, or they're using wifi from the ISPs router.

I'm betting a lot of home users figure they have the router from the ISP, so they don't need anything else.

That these are ISP models doesn't diminish the number of people who could be impacted ... it greatly magnifies it. Because most people who don't know better (and a few who do) connect their PC directly to the ISPs router.

Honestly, go talk to a random neighbor .. see if they have anything between them and their ISPs router. My best is they don't.

When the question instead became, "we're going to put things into space for $50M - how are we going to do that?" a whole new engineering methodology unfolded.

If NASA never existed, do you think there would be any private space exploration today, much less "putting something in space for $50M"? You think there would have been nuclear energy in the 20th century without a Manhattan Project?

It's easy for a company to pretend they hit a home run when they start the inning on third base.

Now I have one of those flippy-key things like the VW and MB owners have, and saved about $35,000 on the car.

That's on my list of things to do for my Audi. Apparently the system has support for fobs, and I have instructions for coding them, but I don't actually have any fobs. So I have to go through the same process. It's an old car though, so it wasn't expensive either... just leaky.

The mechanics I've talked to say pretty much all the 4.2 liter Audis they've seen have been leaky... story of my life with bored-out versions. The 7.3 Ford is the same way.
