Comment Re:baseball pitcher.. (Score 1) 61

Don't worry: it's still an painfully useless analogy if you are familiar with baseball. You really aren't missing anything.

Major League Baseball (MLB) rule 2.04 specifies that " the distance between the pitcher’s plate and home base (the rear point of home plate) shall be 60 feet, 6 inches" (18.44 meters).

MLB rule 3.01 specifies that the ball be "not less than nine nor more than 9 1/4 inches in circumference". That is 72.64–74.68 mm in diameter, let's split it down the middle and use 73.66 mm.

The MLB definition of a strike includes "a legal pitch when so called by the umpire, which: [...] is not struck at, if any part of the ball passes through any part of the strike zone".

A United States quarter is 24.26 mm in diameter.

Thus, the difficulty of aligning the transceivers is similar to the difficulty of throwing a ball of 73.66 mm diameter through a hole of 97.88 mm diameter from a distance of 18.44 meters.

There, now anyone in the world should have a good idea of how difficult it is. ;-)

Comment Re:Time to take nuclear seriously.... (Score 1) 234

My view? Nuclear is a good stopgap to reduce the amount of air pollution released while we get our energy sector heading in a direction more viable in the long term.

I used to share this view. Now I see nuclear as just too expensive. A nuclear plant in my state shut down a few years ago because it wasn't cost-competitive with burning fracked natural gas. As the R&D is done to make nuclear safer and cheaper, it has to chase continuing cost reductions for solar and wind. Improvements to the grid (which are a good idea anyway), and storage are probably a better use of resources. Distributed production and storage of electricity could make for a more resilient energy infrastructure.

Waste reprocessing needs improvement.

Reprocessing is not done mostly because making new fuel from raw uranium is cheaper. With solar becoming cheaper than coal, reprocessing may never become economically viable. We should look into whether building some fast reactors to "burn" existing spent fuel stockpiles is the best way to deal with them. (Expensive electricity, but there is value in reducing the radioactivity of the waste.)

The leaky barrels buried under the western US are kind of a bummer...

Bummer indeed, but those barrels mostly originate from weapons production, not power production.

Comment Re:Pascal, by chance? (Score 1) 241

a new Advance Placement course "will be offered in more than 2,000 U.S. classrooms this fall...the largest course launch in the history of the AP exam."

Are they still teaching Pascal for AP Comp Sci, by chance?

AP Comp Sci replaced Pascal with C++ in 1998 and C++ with Java in 2004.

...and don't tell me to get off your lawn, kiddo--I graduated high school before AP Computer Science was even a thing.

I will add that with the today screen width, 8 spaces tab is really not an issue.

It's not just a matter of screen real estate. At least one study (see the book "Code Complete") found that test subjects scored lower on code comprehension when indent widths were smaller than 2 or greater than 4 spaces.

The records have to be absolutely 100% completely free of dust or any other particles, otherwise the laser will read them as if they were the actual groove, leading to a lot of unwanted noise. A normal pickup pushes aside most of the dust.

It's a neat idea, but it's much worse than a decent pickup on a normal turntable.

Five lasers, but no vacuum to suck dust particles off the surface just before it passes under them?

Then you'll be able to just relax and enjoy a 3d show from the comfort of your own home.
If you end up wanting to watch a 2d movie (some people still watch the occasional black and white or silent movie) you'll be able to put on your VR goggles and simulate any theater you like. People will be able to engage in far more escapy escapism with VR.

People thought that photographs, movies, talkies and color movies were all gimmicks when they first came out.
The scientists and engineers have been doing their part to make VR possible. I can't wait to see what the artists do to make VR jaw droppingly awesome.

Comment Re:Theatres are terminal (Score 1) 331

I came to say almost exactly the same thing. Fortunately I did a quick search first.
We now have decent VR goggles.
Eventually we'll have resolutions that match our retinas, 60fps and near perfect head tracking.

I could imagine movies morphing into something more like a video game. Maybe you could watch the battle of Helm's deep and decide which part you want to focus on or pick up a spare Orc sword. There will probably be modes where you can watch it with friends and see them dressed in character it won't matter if they're in the same room or across an ocean.

Once you have that I don't see why anyone would want to go to a theater to watch a movie.

Comment Re: Mall shooting in Germany (Score 1) 193

The US Constitution establishes an entire branch of government with the express purpose of interpreting the meaning of laws. That branch is tasked with establishing just how much wiggle room there is.

Furthermore that same constitution has detailed provisions for self modification. A 2/3 majority can alter or even repeal any amendment and supersede even the body of the constitution.

There is nothing sacred about the current form of the constitution. It simply states current law and the founders took great pains to make it alterable specifically because they had the foresight to realize that future circumstances might be better served by different laws.

You're implying that there are only 2 sides to the gun debate and that they are equally stubborn.

Neither of these is true.
At many points throughout this thread I have specifically stated that I do not support an outright ban on guns or any sort of totalitarian control.
I have also explained that I do not have an entrenched position and have even told you exactly how you can change my mind.

Provide evidence. That's what I've been doing throughout this thread.

I may be mistaken about the value of gun control but it's a conclusion I reached by examining the available evidence.
As I said before, if you or anyone else can present credible evidence that gun control is a bad idea I would reconsider that position.

We actually do limit freedom of religion and freedom of speech.
A particular religion my require underaged sex or corporal punishment but those practices would still be forbidden in the US. There is currently an active debate regarding the interactions of freedom of religion and same-sex marriage.
Limits to free speech go even further. Lies are forbidden in many settings; under oath, in advertisements or where it constitutes defamation. Copyright holders can limit the speech of others where it comes to works they own. Disclosing insider information of publicly held companies is tightly regulated. The list goes on.

You further err in assuming that I advocate for the removal of all guns. I have never stated that and I do not suggest it. Many countries have gun controls without banning them outright. Germany, to use the original example from this thread, allows for the possession and use of guns but regulates them.
