It was, from my memories as a child. I also remember Mark Twain as having an appreciation of engineering, with his fascination with riverboats and the adventures of the Connecticut Yankee in King Arthur's Court.
There was a famous short story by Mark Twain, titled "The Million Pound Bank Note". It described a young man, the pawn of two wealthy men making a bet, that he could bit survive with only a million pound bank note. The key was for the young man to convince people that he was an eccentric wealthy man, rather than personally poor, and he was never forced to actually _deposit_ the bank note.

> it is all about free access to code after all, nothing else, not politics
_Life_ is about politics. Free access to code, without returning information to the community, has led many companies to participating in a tragedy of the commons. One of the most infamous examples of a company participating in, and then abusing, the free software and open source communities was SCO, who abused various Linux software of containing SysV UNIX code which it turned out SCO did not even own.
The possibilities already exist, in physics and in resources, for thallium to provide fusion power. I was quite startled to learn this, it gets little attention compared to hydrogen fusion.
One can, indeed, buy heavy water, the economic and thermodynamic cost of refining it is large: it takes more power than the fusion reactions produce until and unless they become _profoundly_ more efficient, and the energy cost of refining deuterium is rarely factored into the "break-even" point of fusion power. The cost of refining the tritium, and the economic costs of refining a toxic, very radiuctive, chemically reactive gas is also not factored in.
It is, possible to for neutrons from fusion reactions to generate tritium from lithium, as a byproduct of fusion. But a single deuterium/tritium interaction produces only one spare neutron. The neutron is what can interact with lithium and produce tritium, but it's not efficient. So a running fusion reactor cannot hope to produce even enough tritium to provide its own fuel. I'm afraid that it still needs a large scale, external source of tritium. As things stand, that means a supporting fleet of tritium producing fission reactors. If you have a fleet of those, they're already producing a great deal more energy than the fusion reactor, so the benefits are small, if any, from recycling the tritium from the fission reactors for fusion fuel.
There _are_ potentially effective sources of tritium, such as fission reactors or even solar sails. but the energy they otherwise handle is so much larger than the results of refining and using it for fsion that it's not worth the extra effort for ordinary energy production.
I agree that the physics is interesting. But the eagerness, and much of the fiscal support for fusion, has been based on the expectation to produce energy with it. There are some more viable approaches. Thallium fusion at least makes more economic and therdynamic sense: it seems possible to recover more energy than is used to create the reaction, and the fuel is far more plentiful. And technologies such as orbital mirrors seem viable to harvest similarly or even larger supplies of energy with less concentrated, less contaminated, radioactive byproducts.
I'm afraid that all deuteriam and tritium based fusion reactors rely on fuel that is in extremely limited supply, especially tritium. Since the main source of tritium on Earth is nuclear decay from fission reactors, if there are enough fission reactors to generate enough of the very inefficiently used fusion fuel to generate significant, they can generate many times more energy from the fission reactors without having to engage in dangerous refinement of the tritium.
It's theoretically possible that thallium, which is much more plentiful than hydrogen isotopes, can be used for susion. But I'm sad to say that hydrogen fusion _cannot_ be effectively used for energy. Every technology that harvest or generate enough of the hydrogen isotopes manages and can harvest so much other energy that hydrogen isotopes re only a useful research byproduct, not a comparable energy source.
I've come to know several SWAT personnel for other, professional reasons. Most of them train frequently, and killing an innocent bystander is normally the end of their career, as much as it might be for ordinary officers.
> Sharia law being forced upon a democratic non-Muslim-majority nation is an irrational fear, i.e. a phobia. Islamophobia, one might say.
Oh, my. Please tell that to Israel, who face the threat of genocide and removal from the face of the Earth by the Muslim nations that surround them every day. And the idea that a nation can be immune from abuse resulting from Sharia law by being a majority non-Muslim is not re-assuring to the neighbors of the new Muslim refugee communities throughout Europe and the USA. Many of the "specific issues" you've referred to are fundamental to Sharia law. These include the subjugation of women, the murder of homosexuals, the murder of people who leave the Muslim faith, and the murder of those who criticize Allah or Mohammed. These are all supported by the nations from which many of these Muslim refugees are arising, and adherence to them is a real concern for their new neighbors.
Other religious communities have had these issues. The genocide, slavery, and abuse of others inherent in the Torah and the Old Testament have been real foundations for murder and abuse throughout Christian and Jewish history. The Muslim community has its own strong memories of the Crusades that ravaged Jerusalem and their community. But please do not simply wave aside concerns about fundamental religious practices with a claim that "it could not happen here!"
There are surprisingly many in local news. There articles are not picked up by the major news services, but I see some very dedicated journalists reporting on local politics.
Let me encourage you to think bigger. The biggest threat to democracy is being invaded by another nation that murders your citizens, confiscates your land and wealth, and indoctrinates your children. The second biggest threat is complete social collapse, from plague, natural disaster, or even economic collapse, collapse that destroys the public's access to the resources to sustain life. It's extraordinarily difficult to maintain a democracy when starvation and death are widespread. The USA came perilously close to losing democracy with the collapse of the stock market and of the farming capacity of the Great Plains in the 1920's.
With that said, there is danger in the press and the government being too united. It's part of a vital social balance of power in a free society.
It's not false at all, in many types of work and many situations. Younger personnel can often work at times, and in circumstances, that we older personnel cannot. Single personnel can often do weekend and holiday work that people who are married or have children cannot. Whether it is legally discrimination does not make it unreal, anymore than hiring junior H1-B's in place of fully qualified American citizens is not attractive to many businesses. Racial, gender, and disablity biased hiring is also illegal, but these are also common place.
Or, I'm sad to say, we could simply die off. The extension of the human life span is another reason for growing numbers of retirees. Population pressure reducing the number of births is another reason that younger workers don't enter the market as much. Women's liberation, freeing vast numbers of women to enter the market is another, especially as working mothers are more and more part of the workforce. The working mothers would not be as much of an issue if the fathers of their children stayed home to care for the children, but it remains unusual, and the parents both seem to work on advancing individual careers.
I've turned down that kind of raise to do work I considered dangerous or immoral. But I had the resources to make that choice. Some of us have family or other obligations that force us to make such choices, choices like supporting family with enormous needs.
> but it's an experiment we can do, so why not do it?
That's a reasonable question. It's a profoundly expensive experiment in terms of electrical power, engineering and scientific time, and the exclusive use of one of the most demanded scientific resources in the world. So those are good reasons to weigh the potential scientific benefit of the results, and include the chance of any usable results.
This seems extraordinarily unlikely to produce any surprises. Is there any theory or experiment in matter with an opposite electrical charge has anti-gravity? They're distinct fundamental forces.
I'm afraid this is not true. Some transgender people are quite offended that straight members of the opposite gender are not attracted. See, for example, https://www.youtube.com/watch?..., where the straight members of the opposite gender are blamed for their lack of acceptance.
It matters for passports, social security, W-2 forms, and the national census, to name only a few standards. It also matters for Title IX based laws and policies.
It's called Klinefelter's Syndrome. I've met several such people in my lifetime. Their physiology, and their gender identity, can be complex and unstable. I've met several, including one who was diagnosed as an adult and changed gender identity from male to female.
The numbers of transgender people have been increasing, especially for children and teens. According to some surveys, the ratio is now as high as 3%. What many of the surveys do not acknowledge is the number of these children who settle down, around the age of 18, to identifying as their birth gender and simply being gay. I'm seeing reports the ratio of teens who simply come out as gay rather than transgender is as high as 90%.
I'm afraid that this is not something that can "trickle back". It requires complete migration of critical system components like RPM, which I'd not expect to see done with Python 3 before RHEL 8. It also requires complex revision of the source packages from Fedora 29 or later. Those packages had tools to compile with and deploy for Python 2, and those hooks have been deliberately excluded.
I'm sad to say that I've not seen any hint of a beta or tentative release date for RHEL 8. There have now been _10_ Fedora releases since the Fedora 19 on which RHEL 7 was based. I'm concerned that RHEL 8 will be either completely obsolete when published, or so divergent from RHEL 7 that there will be no effective upgrade, RHEL and CentOS users may as well consider a switch to other Linux or UNIX systems. RHEL 7 came close to suffering this problem with the switch to systemd,
