Comment because people dont change (Score 1) 271

one thing that has been proven repeatedly is that people dont change because you punish them. in order for them to change, they have to want to change and even then they are likely to fail. some things just can't be changed without behavioral reconditioning aka "brainwashing" and it's not always permanent.

as for it's relevance, would you want a guy like this to be a teacher?

just sayin.

Comment Re:Web support (Score 2, Informative) 80

When I've read "web support" I though "Cool! I will finally get good support to run QT apps on a standard browser".

actually, you can do that

But alas, it just means running a Chromium engine embedded in a QT app.

no, it uses WebKit while Chromium uses Blink, a fork of WebKit.

Who wants to run web sites in an app nowadays instead of opening them directly in a browser?

well... if you wrote a web browser in qt you would. what about an RSS feed reader? it has it's uses but it's true it shouldn't be abused.

QT is a huge stinking pile of bloatware. I eschew it.

You are right, QuickTime is bloatware. However, Qt is well written and you are given the option to build only what you need and which libraries it should use. The render engine is exceptionally flexible too, allowing it to leverage many different methods of rendering. Don't have X? no problem, add a runtime argument (-platform linuxfb) and your qt program will display using the linux framebuffer. Qt also builds for desktops (e.g. Linux, Windows) and embedded systems (e.g. Android, iOS) and is easy to cross-compile for your device of choice.

if you think GTK+ is slimmer, guess again and check your binaries.

I am afraid of getting hit by lightning, and getting bit by a shark, but not so afraid that I won't walk in the rain or swim in the ocean. I just take reasonable precautions.

what reasonable precautions are we taking? with our current program, we'll be lucky to see a killer asteroid coming much less do something about it.

Let's say that a solar plane is white, and a commercial airplane is black.
I bet that your "functional airplane" is still very much dark gray : you still need a pilot, copilot, food, toilets, a few luggage and minimum space for feet and belly.

perhaps you should watch the video i linked because it doesn't seem you understand what i have written. in any case, a solar plane only needs to be solar powered. there is nothing specifying its shape, size, battery capacity or even propulsion system.

i made no claim that this ultra-lightweight solar-powered plane could be used for a commercial flight filled with cargo and hundreds of passengers,

You did indeed make that claim:

it's entirely possible to replace our environmentally destructive planes with solar planes

you have inappropriately conflated the idea of a solar plane with that particular solar plane's design.

There's a pretty big difference between a solo flight in an ulta-lightweight solar-powered plane and a commercial flight filled with cargo and hundreds of passengers. Note that they've had to wait for months for a clear weather window, and you're claiming that it's now possible to use commercial solar-powered planes?

by changing my claim, you have used the strawman fallacy. i made no claim that this ultra-lightweight solar-powered plane could be used for a commercial flight filled with cargo and hundreds of passengers, only that the underlying technology made it possible.

it makes it very clear that it's entirely possible to replace our environmentally destructive planes with solar planes.

Once again : Not, it's not possible.
Here's a comment I posted 5 years ago : http://science.slashdot.org/co...

...
Conclusion : The orders of magnitude just don't match, even with 100% efficiency => Commercial flights as we know them & photovoltaics are incompatible.

by adding "[c]ommercial flights as we know them" you have used the black and white fallacy. solar airplanes could be different in many ways but that doesn't mean they suddenly aren't functional airplanes.
