  1. Re:no anticipation (making you wait) secret sauce on US Once Again Boasts the World's Fastest Supercomputer (zdnet.com) · · Score: 1

    How is this any different than a data center of the same scale?

    High speed interconnects, and much more computing power, mostly in the GPUs that many headless data center servers don't even have.

    I am sure it will have way lower latency between nodes at any equivalent bandwidth tier.

    Duh.

    But unless you're planning to aggressively exploit that ...

    There are plenty of critical applications that benefit from fast interconnects.

    You can rent a lot of processing power on Amazon, but you can't rent a supercomputer-grade high performance interconnect between your nodes. Not from them, anyway.

    Tulips are edible, and were eaten during famines. The core of the bulb contains some toxic glycosides that can cause diarrhea and vomiting, but if you trim that out the rest is fine.

    Hey guys, this IS Google. Don't get too attached to this service.

    Google is paying a price for their engineering cycle of "build-deprecate-kill". They are suffering from employee attrition, as developers realize that nothing they do will ever get out of beta.

    Attrition is especially severe at the Waymo subsidiary. Waymo is ahead on the tech, but there are no path to an actual product, so engineers are jumping ship to Uber and elsewhere.

    Trees are not free. They take up valuable space that could be used for more profitable things.

    The main source of CO2 is not "corporations", but personal transportation and residential power. It is YOU, not "them".

    The root problem is mostly cheap/crappy industrial AC motors. Replace them with variable speed DC motors and the reactive load mostly goes away. The new motors will pay for themselves in a few years with lower energy bills.

    I pass about 8 school grounds (covering all age groups)

    Where I live (San Jose, CA) the elementary schools ban devices. They can be powered off in a backpack, but can't be turned on during school hours.

    Middle schools and high schools are more permissive, banning only in-class use. At my daughter's high school, any student whose phone rings in class has to get up in front of the class and dance The Macarena. This is a surprisingly effective deterrent.

  11. Didn't Japan have civilians producing war materials in their houses by the end of the war?

    By then it was too late to make a difference. Much of the production was useless crap, or purely ceremonial, like the hand knitted "death shawls" issued to the Japanese soldiers sent to Iwo Jima.

    Both Japan and Germany planned for a quick "knockout" victory, and a very short war. Months, not years.

    Germany actually came close to knocking out the Russians before winter and the Moscow counteroffensive. Japan's strategy was completely delusional.

    If the pay is junk, it means costs are down. Investors like to hear that, donâ(TM)t they?

    Any sensible investor would see this as a warning that payroll expenses are likely going up, and profits may decline.

    Except that China's current account surplus has mostly disappeared. China actually slipped into deficit for 1Q18.

    Why is this even news?

    Because it is about salaries at a tech company. What could be more relevant to Slashdotters, other than maybe the cost of renting a basement?

    I am surprised Microsoft is publicizing this. They are hurting recruitment by broadcasting that they have crappy pay, and raising expectations of salary increases among existing employees.

  15. What is relatively new though, at least as far as I can see around me in Europe, is that an increasing number of formerly semi-permanent jobs are being turned into gigs.

    Perhaps, like in America, this is something everyone "knows" is true, but actually isn't.

    Can you cite any evidence that "gigs" are more common in Europe?

  16. Re: Let me fix that for you... on There Are More Jobs Than People Out of Work, Something the American Economy Has Never Experienced Before (cnbc.com) · · Score: 5, Informative

    Labor demand is high, so salary is how the companies will compete for labor.

    That's the theory. But so far it isn't happening. Wages are barely keeping pace with price inflation. Economists don't really understand why. With tight labor markets and loose monetary policy, inflation should be roaring. But it isn't.

  17. Where we kinda had to allow women to work because we didn't have enough men to do the jobs available?

    A higher percentage of women are in paid employment today than during WW2.

    We actually did a rather poor job of mobilizing women during the war. But Germany and Japan did far worse, because they were ideologically committed to keeping women at home.

  18. The gig economy is ultimately not sustainable.

    Lawyers have been hanging a shingle and doing "gigs" for centuries. So have plumbers, carpenters, etc.

    the recent law school graduate that might be in an area saturated with lawyers might advertise basic services for dirt cheap just to get money

    Or he could move to where pay is higher. The principles of supply and demand predate "gigs".

    With science, unlike mathematics, there is never certain proof. All we ever have is evidence. Once the degree of uncertainty is small enough, it is a discovery.

    it doesn't seem likely ANYBODY will discover life on another planet...

    Not true. We will likely find life on exoplanets soon. We just need some improvements in spectroscopy so that we get detect molecular oxygen in their atmospheres as they occlude their mother star. That is a sure sign of life. Other than photosynthesis, there is no other plausible explanation for high levels of O2.

    The James Webb Space Telescope will launch in May 2020, and can do atmospheric spectroscopy. We may get our first sign of exolife shortly after.

    Why use nukes? Solar is bright and plentiful in space, and can power ion thrusters.
