Comment Re:not reasonable at all (Score 1) 826

I think the fear people have with binary logs is that, if you get corruption, a human feels like they have a hope of decoding what the text was supposed to mean.

Although I think this is pretty naive - people thinking "dropped characters", as opposed to the more usual "50 consecutive messages disappeared". A binary format with proper message boundaries is exactly as robust as a text file in that capacity.

What's broken exactly?

Software has bugs and occationally they crash. I'm not an expert GNU/Linux system administrator by any means, and I've lost count of the amount of times when I simply wanted to just find a way to make the init system restart a service automatically when it crashes. This is trivial with Systemd, you just set Restart=on-failure in the service file and it's done. No need to write error-prone shell scripts or fiddle with run levels. It just works and it's well documented.

Straight out of Windows. Write buggy software. It's ok if it crashes once in a while because we can just restart it.

Also straight out of Windows. Make everything into one big integrated binary instead of something that you can see into or hack on.

Write non-buggy software. Hope you have the millions per line of code they paid the space shuttle team.

Again: so?

We've reached monitor parity. We reached it because TV improved and there's no point trying to maintain a difference for difference's sake.

But the vertical height argument is just rubbish. People run 16:9 and 16:10 screens vertical all the time, and no one was ever going to be manufacturing giant squares which physically wouldn't fit on a desktop. 4K and the like is going to sell principally to the computer market first because lord knows there's little need for it in home theatre for most people.

Comment Re:Why gravity is treated as a force? (Score 1, Interesting) 97

Because it is a force? A force is anything which transfers momentum and energy around. Which gravity does.

Moreover, what seems so obvious to you that gravity is the curvature of space time? What does that mean? Because it is in no way obvious. For example, if gravity is spacetime curvature, then it doesn't really pull on things in 4D spacetime since we've already defined it away. So why do things appear to move down gravitational wells? Are they elastically colliding with a sheet of space time? Why aren't they normally deflected by it?

Finally, it doesn't matter what new theory shows something is or isn't. It has to verify old theory. And old theory says that gravity looks and acts, in the human range of experience, like a conventional force identical to any other. So whatever it is, it has to be simply back down to confirming our everyday experience.

Which is why I presume they've been shutting off cell towers in areas with protests ... oh wait, they haven't done that at all and it would be a lot easier! (also possible, just have the police deploy cellphone jammers...what's that? You mean the FCC ruled those illegal and took them away from the police. Well nuts...clearly their plans for tyranny are even more sinister!)

And ...what, also delete photos already uploaded elsewhere? Or stop new phones coming in ? Or TV crews? Or does in your scenario the government bricks phones continuously, and yet somehow you think people would just be "ok" with this and it's a function you'd ever be able to use more then exactly once?

We have those ultrasound acoustic weapons - highly directional noise projectors. Presumably the volume of wildlife isn't very high, so you could watch the sky with a camera and then direct some sound which they treat as "fly away from" at any birds which crossed over a safe zone. Most nearby wildlife would quickly figure out where not to go.

Comment Re:Fusion Has Already Failed (Score 1) 305

Look at ITER: $20B and rising, it will only make 500 MW(th) -- six times less thermal energy than a 1 GW(e) fission reactor -- and it doesn't even include the advanced materials needed to withstand commercial reactor levels of integrated neutron flux.

Well, that's ITER's point now isn't it? We know what is required to make fusion work, we just don't know how long we can sustain a reaction because we do not understand how the large neutron flux will affect the materials in the container and we still have difficulties maintaining the containment. It's an engineering problem now, not something that is clearly impossible.

IMHO, investments in such experiments should be expanded, by both government and industry. Just like getting a man on the moon, We need a JFK'esk commitment to making this work.

ITER is also heavily instrumented and represents the design prototype for power generation. It's successor - DEMO - is expected to be bigger, but cheaper, because the design will be known, the manufacturing for the parts will be understood, and it won't include the scientific instrumentation since it'll be a power generating reactor, not an experiment.
