Sleep Deprivation Lowers School Achievement In Children 272

New submitter josedu writes:"Sleep deprivation is a great, hidden problem that afflicts a great percentage of children in affluent countries. About 73% of 9- and 10-year-old children in the U.S. are sleep deprived, as are 80% of 13- and 14-year-olds. The new study thinks this is linked to the increased access to devices such as mobile phones and laptops late at night. One of the researchers put it very simply: 'Our data show that across countries internationally, on average, children who have more sleep achieve higher in maths, science and reading.' This disruption is also causing schools to dumb-down their instruction to accomodate the reduced capacity of these kids. Thus, even the kids who are getting enough sleep will suffer. The long-term impact of sleep deprivation on nationwide education levels is enormous."

GNU is considerably larger than Linux. My paper napkin calculations show the entire kernel to be roughly half the size of gcc. No, not including g++, just gcc. So if a distro is built and distributed with gcc as the default compiler, then it's already more like GNU/Linux. Most Linux-based distros, though, easily come with 10 times as much GNU.

Hehehe. I, for one, don't understand for the life of me why it is OK to share videos of soldiers shooting at children with automatic weapons, for real. Or what Lucas did with kids in the prequels. How is that OK, and a depiction of a fictional sex abuse act is not OK? I think children involved in actual acts would strongly agree with me, too.

Or what about any movie where a super-villain is trying to destroy the world? Why are we OK with looking at that imagery? Isn't that the worst fucking thing that one can try to do? Why do people get gold prizes for depicting this, and prison time for monkeys with no clothes on?

This whole bit of FUD is based on taking two words out of context in a list of features that Samsung could have changed to not infringe in the German design patent infringement case. Specifically, Apple said that their patent claimed A+B+C+D+E+F+G+H, etc. with one of those things being rounded corners.

Look at the patent, which, by the way, has 1 content-free claim (you didn't know that?), and a few crude pictures. I remember drawing things like that in high school. All I claim is that it's been thought of before, but nice trolling.

Note that Stallman's solution doesn't include either of those requirements, and therefore lacks the same moral justification.

So his argument is flawed because he didn't chew it up for you like I did? Try again.

It is sickening in the extreme to think that it's possible to deny other people access to information, simply because you thought of it first.

It's worse than that. Patents don't deny access to information, but they curtail our freedom to help each other. And those who register patents almost never think of it first. Did Apple think first of a rectangular device with rounded corners?

As usual, Richard Stallman has a great solution:

We should legislate that developing, distributing, or running a program on generally used computing hardware does not constitute patent infringement.

This will work because a very similar law already works in the medical field. Just like surgeons, who can safely ignore procedural patents to save lives, programmers and distributors of free software deserve complete patent immunity because their work is entirely gratis, and benefits the whole world.

Yes, yes, yes. The submitter sounds like he wants to digitize a bunch of files, so I would recommend a good file system. Any stable filesystem will do, like ext4 for instance.

Avoid metadata within a file for as long as possible. It will bury you. If date and bill amount is all you need, then just stick them into the file name.

Now you can pile your files into, say, ~/my-files/ in any way whatever. You can create a category tree, for example, to allow you to find files in a file manager in 3 clicks. For more complex tasks you can just use bash, find, and the rest of the userland. It does not get simpler or more portable than that. In particular, it is trivial to convert this structure into a CVS, which you can suck into a spreadsheet or a database of your choice.

Have we taken photos of an actual black hole? No.

Lensing effects in visible light should count as a photo of a blackhole, IMHO, since the event horizon is theoretically invisible.

And no, a black hole is not god dividing by zero.

Could easily be a god dividing by every real number other than zero, which would be good enough.

You seem to think that an appeal to authority is a valid rule of inference. In mathematics, too. Oookay.

Does it occur to you that just because some way of doing science is very popular, it doesn't mean it's valid, or even superior?

Please, don't reply (unless you wont to agree for a change), just ponder.
