Comment Re:The three keys on the top-right (Score 2) 698

If you expect to need it, create the file /proc/sys/kernel/sysrq with the contents set to 1. This makes the key combo active by default, and survives rebooting.

The /proc directory is a virtual filesystem; nothing in there survives rebooting. If you want the sysrq keys to remain enabled after a reboot you need to write to that file from an init script.

The most conspicuous organisms have long since been cataloged and fixed on the tree of life, and the ones that remain undiscovered don't give themselves up easily.

Certainly not true if by "conspicuous" they mean "ones you can easily see with the naked eye." Most insect and beetle species are not cataloged yet, and for smaller critters the situation is even worse. Heck, you might even find a new frog species in Manhattan.

Yes, we know that you worked for power companies as a desk clerk or a cleaner. You keep advertising that alongside your utter ignorance of basics of power generation. Sutor ne ultra crepidam.

Not going to bother with the rest. When you deny that sudden outages cause cascade failures, something that is routinely demonstrated in developing countries and sometimes occurs in developed countries when cascade failure across all safeties happens to align, you cannot discuss the topic. It's like trying to argue math who starts with "no you're just assuming that 2+2 in decimal system is 4 which is wrong. It's actually 77.6, and I know this because I worked in university at a math faculty!"

IR seekers are really easy to make and it's a fun robotics project. Simple to do with analog controls even (the principle is so easy it was highly classified for years). Launch your rocket into the Sun every time.

Tracking a specific target instead of the brightest heat source is much, much harder, but if the drone is the only dark spot in the field of view of the camera, that should be do-able. Fun to try, anyhow.

Comment Re:3%? Where did you get that from? (Score 1) 484

Dear mathematically changed moron. I do wonder how you got on a computer-related site which generally requires people to actually comprehend basic math, which you fail at.

It's very, very simple.

Your reactor takes a certain fuel rod (depending on reactor type this can be anything from natural levels to various stages of enrichment). This rod is considered to be 100% fuelled. The actual levels of U235 compared to rest of contents is only relevant from point of view of what kind of reactor you're using it in - it's wholly irrelevant for the scope of this discussion which does not specify reactor types.

You use the rod in the reactor, moving it within the reactor as it slowly depletes. Eventually when there's around 96% of original U235 contents still left in the rod, the rod is considered "spent" and needs to be enriched back to original 100% level (which again can be anything from natural uranium content to various enriched levels depending on reactor type).

Easy math: fully fuelled rod just inserted into the reactor: 100% fuelled.
"Spent" fuel rod: around 96% of the original contents still in the rod.

Do us all a favour, and get through elementary school math before your attempt to discuss mathematics on slashdot again.

Your first statement is factually incorrect, as the trend of "sane energy policy equals cheap energy prices" is easily visible in other states. Finland for example has a large installed nuclear capacity in addition to having hydro pretty much everywhere where it's easy enough to install, while having minimal "not yet ready" renewables installation. Energy is cheap.

Compare to Denmark which went full out on wind power and shut down the burner plants. Energy price astronomically high.

Notably, this is also seen in heavy industry. While Germany, realising what Energiewende would do to their heavy industry opted to subsidise heavy industry and let the rest bear the burden. Results were well documented.

Rest of your argument is frankly inane to the extreme and could only be argued by someone utterly ignorant of reality of strategic sectors and how they are protected. Energy, food production, water and so on are strategic sectors required for existence of a functioning state. As a result they are heavily regulated and subsidized to ensure their seamless functionality regardless of market forces. Arguing against this on "free market" basis is utterly inane simply because lack of these subsidies and regulation in the said sectors would cause societal collapse, as failures in these sectors would be strategic failures causing failures of state structures.

And as has already been explained in this thread, only ignorant people would think that this item is about "winding down France's dependence on nuclear". It's a PR stunt, aimed at ignorant and opinionated people like you who would make such sweeping and utterly incorrect statements and feel that this is an accomplishment for their anti-nuclear crusade.

Actually no, no it's not. Toy model aircraft aren't subject to any such law, FAA-wise. Yet, at least. If anything, we're talking about good old fashioned reckless endangerment, which has nothing to do with model aircraft in particular, but could be a charge in such a case (just like it would be if they were throwing lawn darts over the fence, or hit somebody in the head with a stray baseball).

The FAA has guidance about such matters. But flying a toy around like that has absolutely zero FAA restrictions in and of itself, with regard to people on the ground. It's likely to be a different story when such a machine is used commercially, but again, zero relevance in this case.
