  1. Re:Bad measurement? on Grand Canyon Visitors May Have Been Exposed To Radiation For Years (azcentral.com) · · Score: 2

    I put a rough 5-gallon bucket shape into the dose calculator for 0.33% uranium ore and got 20uSv/hr at 1cm distance. Still a factor of 400 off (but not the 20,000 you got: article said 800mRem/hr contact). http://www.wise-uranium.org/rd...

  2. What a fantastic service! I wonder if they offer a password-changing option as well?

    [Angry customer]: The software I was using crashed with an assert code!
    [St. Peter]: Yes, we'll have to talk to the car manufacturer about that.

    Most of the software I work on can emit smoke, mangle parts, or lose data if it were to abort. There's a place for assert(), but it's not always an option.

  4. You can't do the math until you've done the science. If you can do the math beforehand, it's engineering. (And most science also involves a lot of engineering, before you get to the unknown stuff.)

  5. Alternate headline: US dollar soars against crypto on Cryptocurrency's 80 Percent Plunge Is Now Worse Than the Dot-Com Crash (bloombergquint.com) · · Score: 2, Interesting

    It's equally valid to say that cash has increased in value by 400% against cryptocurrency. You should buy dollars now! Disclaimer: some cryptocurrency people are saying that the current value of cash is just a bubble.

    In other news, cash held fairly steady against other easily tradable commodities, with no major movement.

  6. Re:Wait, are you saying everything changes? on Baltimore Police Department Is Still Using Lotus Notes (baltimoresun.com) · · Score: 1

    Cars last about 15 years. They can last 50, or 5. When you replace them depends on the economics of keeping them running. When you can't get service techs, and parts shoot up in price, you figure out how to migrate to and finance a less expensive car.

    If your local police department was running a fleet of 30 year old Ford LTD Crown Vics you would rightfully question the economics. And (possibly) rightfully decide to keep them running.

    Lotus Notes is nearly 30 years old, though its architecture dates to the early 70s.

  7. My old Timex from the seventies needs to be wound every day (assuming I want to use it).

  12. Node.js /usr/bin/node on Hey Microsoft, Stop Installing Apps On My PC Without Asking (howtogeek.com) · · Score: 1

    BTW, I'd really like to know why the Debian people decided to rename NodeJS to just Node. It took me quite a while to figure out why NodeJS didn't exist after having installed the package. Renaming the main executable for no damn reason will do that!

    The Node.js folks also call the executable node, so, um, maybe they use Debian too?

  13. According to the post-launch press conference, they landed them because they wanted the grid fins back. Apparently they're rather expensive machined titanium, and were specially made for the "heavy" configuration.

  14. Re:Newton. on Ask Slashdot: How Would You Explain Einstein's Theories To a Nine-Year-Old? · · Score: 4, Informative

    Newton didn't get the energy part.

    Einstein (as I understand it) and the rest of the physics world had a problem in that Maxwell's Equations did a really good job of describing electromagnetism. However, the wave equation that pops out does not account for the velocity of the observer. This implied that the speed of EM radiation (light) is constant for ANY observer: oh dear. Einstein (and Lorentz) hypothesized that time didn't have to be the same everywhere, and came up with Special Relativity to describe it. And, remarkably, SR was shown to be accurate. It's also how energy gets mixed in with mass.

    A handful (nearly two hands full) of years later, Einstein published General Relativity as a description of why acceleration looks the same as gravity. (Inspired by Newton's F=(constant)*Ma=GMm/(rr).) He did this by hypothesizing that distance is not the same everywhere. And, remarkably, GR was shown to be accurate. (He needed some help from other mathematicians, because the math is hard for warped spacetime.)

    Maybe the above is not quite kid-friendly, but Einstein challenged the ideas of classical physics (time and space being "flat"), and got it right. Or at least the next-level-of-right.

  16. Re:Extensive documentation? on Ask Slashdot: What Are Your Greatest Successes and Weaknesses With Wine (Software)? · · Score: 1

    Extensive does not mean "lots". It means far-reaching---you can write something extensive in one sentence. e.g., "A communications disruption could mean only one thing: invasion." (See also, fake news, Last Jedi.)

  17. One of the reasons I picked Tradfri over other other "smart"/IoT lights and switches is because it's all local---no cloudy stuff supported except for the things I've explicitly connected. However, there are a number of silly bugs and missing features that make it practically unusable. So, I'm still searching for lights and buttons that work, and my X10 system is still being used....

  18. Re: I still use them on A Global Shortage of Magnetic Tape Leaves Cassette Fans Reeling (wsj.com) · · Score: 1

    I bought gold-plated optical cables at Fry's last week. It was the cheapest option. And, yes, there really was a tiny gold-colored ferule around the fiber. I'm sure the photons are much happier and crisper now.

    (Crutchfield link since Fry's doesn't have a description.)

  19. I was testing some components (class D amplifier) and wanted a quick signal source, so I hooked up my phone. I was quite surprised (and concerned) to discover that my LG G6 is pumping out a VERY LOUD signal at 50kHz. I can't hear that high (I stop at about 12kHz now), and earbuds will attenuate it quite a bit, but I imagine it could still cause hearing loss. (BTW, I was looking for ~250kHz noise in the amplifier, but that component was attenuating correctly. It faithfully reproduced the 50kHz whine, however.)

    I won't be listening to music on this phone... now I have to test my other phones.

    If you have issues with HDCP, then get an HDMI splitter (stripper). They run about $10; but check the reviews to make sure it's a cheap model; not a fully compliant one. If you don't have HDMI, then you may also need an HDMI->component converter, which runs about $20. Then you'll need to spend $30 on cable management for the ridiculous rats-nest you'll have just made. I eventually gave up on this setup for my ancient (but decent) HD plasma set, and spent $400 on a 4k screen of similar picture quality, but with fewer headaches....
