You can stare at the full moon all night if you like, because the albedo of the moon has filtered most of the light including the UV band that naturally passes through our own atmosphere. The three mile circle illuminated by a mirror would bounce a significantly higher amount of UV than the moon's albedo. If you treat the 60ft reflector as an analog to a pinhole in a pinhole camera, the circular area on the Earth surface would be a rough projection of the image of the sun.
(1) I wonder how they calculate the UV exposure for the observer on the surface within the illumination area.
(2) I wonder if you'd be able to detect places in a coherent projection where sunspots or coronal ejections are reflected through the "pinhole" effect of this arrangement.
> The problem is when it costs MONEY to develop
It usually does, but we've somehow made free software for most tasks, and we maintain it. In some ways we do it better as free software.
Sometimes. And sometimes, development is faster with restricted sharing and per-copy fees. If faster development was the only issue, then maybe restrictions on sharing could be ok.
But there are other things like how much everyone should be able to know about the software that increasingly runs our lives, like whether people should be able to verify the security of some software, or audit the response to a security incident. Free software makes society better in those ways.
Also, you mention maintenance. We should keep in mind that the cost of maintenance is increased when only one person is allowed do the maintenance. So high costs is an argument for wanting money, but it can also be an argument for using a lower cost path, such as allowing everyone to do the maintenance, either for free or in a competitive market.
He advocates sharing, and the GPL allows sharing.
He says to ignore laws that block sharing. That means ignoring some parts of copyright law. Some other parts of copyright law are fine. There's no contradiction.
(And if someone has a follow up question about sharing everything, no, he doesn't advocate for sharing everything. Some stuff is personal, for example. He's in favour of sharing generally useful technical information, such as the source code of software that has been given to you.)
When is the US Army going to liberate these neighbourhoods until only the people that take good decisions are left?
23% of that debt is owned by the Bank of England ("Gilt and Treasury Bill Holding"), which in turn is owned by... the British government.

In short, it is a choice to be beholden to the bond markets in this way. It is a political choice to outsource the fiscal margins of government spending to the financial sector, and paying them lavishly for that privilege. And no, I'm not saying this means you can spend endlessly on anything without very bad consequences. It's just that it's a very expensive way to provide the money supply and private savings, while giving enormous budgetary power to a sector that has proven time and again that it's unable to properly manage the economy's funding (if it's even interested in that at all, rather than just in enriching itself).
Anubis has the side effect that it stops the internet archive crawler.
Even though it whitelists the IA crawlers by default?
Anubis has worked well for us to get rid of most of the scrapers from our wiki, including the ones faking regular user agents.
It's not just data centres, many of the requests from regular broadband IP addresses. I think they're using "services" of bottom feeders like Scraper API, or buying from the authors of malicious web browser extensions.
Make headway at work. Continue to let things deteriorate at home.
