Why the Universe Didn't Become a Black Hole

ChrisMaple Stable universe? (109 comments)

TFA proposes a kinda-stable universe if it contains an exact amount of stuff, not one neutrino more or less. My question is: "If the universe has net angular momentum, can't it be stable for a large range of stuff?" much like a solar system?

Processors and the Limits of Physics

ChrisMaple Wrong, wrong, wrong (167 comments)

Power use is proportional to the chip's operating voltage

Wrong.

transistors simply cannot operate below a 200 milli-Volt level

Wrong. Get the voltage too low and they won't be fast, but they won't necessarily stop working.

And of course, the analysis of the communications issue is also wrong.

There are obvious and non-obvious physical limitations that limit scaling, but nobody is being helped by this muddy, error-ridden presentation.

Processors and the Limits of Physics

ChrisMaple Re:Seems simple enough (167 comments)

The most recent IC transistors - FinFETs and the like - have the control element (gate electrode) on three of the four sides of the gate. The gate-to-substrate region is rather a small part of the gate surface, compared to processes a decade ago; this should reduce the magnitude of the floating-body problem.
Alas, my knowledge of this is becoming obsolete, so I could easily be wrong.

Ask Slashdot: Can Tech Help Monitor or Mitigate a Mine-Flooded Ecosystem?

ChrisMaple Difficult (123 comments)

Quesnel Lake is 100 square miles, and the second deepest lake in Canada. If something has to be done that involves the whole volume of the lake or all of the lake floor, it's a very big project no matter how clever the solution.

Ask Slashdot: Can Tech Help Monitor or Mitigate a Mine-Flooded Ecosystem?

ChrisMaple Re: Make them pay (123 comments)

Nice deflection with euphemisms. "Public control" in your context is government control; and as soon as the publicity goes away you've created a self-perpetuating incompetent bureaucracy that will not do its job.

Ask Slashdot: Can Tech Help Monitor or Mitigate a Mine-Flooded Ecosystem?

ChrisMaple Re:What would I *not* do? (123 comments)

Recent (several years) Congressional efforts to examine the contents of Fort Knox and other U.S. government gold reserves, and the gold of other countries that the US holds in trust, have been rebuffed. Germany has been refused access to its gold that is held by the U.S.

There is good reason to believe that for all practical purposes, Fort Knox is empty. The gold has either been stolen by groups within the US government, or used by the government itself to pay off overdue debts.

We are well and truly screwed.

Slashdot Asks: Should Schooling Be Year-Round?

ChrisMaple Re:No, school should not be year-round. (421 comments)

With 5 children, my mother in law (a retired Catholic School Teacher) told us to Home School for public and some Christian Schools were not good anymore.

I've read that sentence 6 times. It still doesn't make sense.

Slashdot Asks: Should Schooling Be Year-Round?

ChrisMaple Re:No, school should not be year-round. (421 comments)

Education isn't about getting jobs or any other such nonsense

<sarcasm> Why of course! All children should receive 13 years of primary education and come out unqualified to hold any job. Makes sense to me, after all, I had a public school education. </sarcasm>

Education should prepare people for life, and if you're not prepared to support yourself through honest work, you're not prepared for life.

Slashdot Asks: Should Schooling Be Year-Round?

ChrisMaple Re:No, school should not be year-round. (421 comments)

Comparing the education of a doctor, lawyer, or engineer with a teacher, seeing that the degree names look similar and that the time to get the degrees is similar, and concluding that the education levels are equivalent, shows an amazing quantity of gullibility. That teaching degrees are bullshit is fully demonstrated by the hundreds of thousands of college professors who've never taken a day of courses meant to create teachers.

Long-range Electric Car World Speed Record Broken By Australian Students

ChrisMaple Re:Can I go anywhere useful yet? (120 comments)

Propane tanks of a given size always deliver the same amount of propane. Batteries, not so. So I should drive in with my new EV, swap out the battery for one near its end of life that only delivers half as much charge and whose internal resistance has tripled? No thanks.

The debate over climate change is..

ChrisMaple Re:Why is there a debate at all? (278 comments)

The Democrat party has been the party of slavery and racism since its founding circa 1828, and in the last 100 years has become the party of power, big government, and crushing individuals. Any policy of the Democrat party is calculated to increase its power, especially populistic ecology policy.

The Republican party is about evenly split between "We wanna be Democrats too" and freedom-lovers, with the former currently having the most power.

ChrisMaple Re: n/t (278 comments)

Do you understand that AGW stands for anthropogenic global warming? Do you understand that saying " it is largely because of people. " looks really silly?

Predicting a Future Free of Dollar Bills

ChrisMaple Re: 666 (753 comments)

Gold also fluctuates, just nowhere near as much. Particularly in the long term: you won't see gold drop to 2% of its value a century ago, as the US dollar has.

IBM To Invest $3 Billion For Semiconductor Research

ChrisMaple Re:Not possible (68 comments)

The field effect transistor was invented in the 1920s. Point-contact transistors date from 1947, and conventional junction transistors from the 1950s.

Here Comes the Panopticon: Insurance Companies

ChrisMaple Who buys insurance? (353 comments)

There are only two types of people who freely buy insurance: cowards and those who think they can fool the insurance company into paying more than the premiums cost.

Both groups are immoral.
