Tried that, but the wholy thing feels ‘clunky’ and often fails in various ways. Nowadays I just use Firefox Hello, which has the added advantage that all that is needed on the other side is a web browser (any web browser that understands webrtc).

## Submission + - Workers in China, India, USA believe AI and robots will replace them (qz.com)

An anonymous reader writes: Chinese workers have seen the future, and it involves artificial intelligence, robots, and other forms of automation replacing them, at least for repetitive tasks. That’s how workers responded to interviews about the future of work (pdf) conducted in 13 countries by the ADP Research Institute, part of the payroll systems company ADP. In contrast to China, a minority of workers in Germany think machines will take over repetitive tasks in the future. Workers in Chile, Singapore, the United Kingdom, and France among other countries agree. But American workers and those in India are inclined to see things the Chinese way; nearly two-thirds of those polled said they thought the machines were coming for repetitive work.

## Submission + - How many digits of pi does NASA use? (kottke.org)

An anonymous reader writes: Mathematicians have calculated pi out to more than 13 trillion decimal places, a calculation that took 208 days. NASA's Marc Rayman explains that in order to send out probes and slingshot them accurately throughout the solar system, NASA needs to use only 15 decimal places.

The most distant spacecraft from Earth is Voyager 1. It is about 12.5 billion miles away. Let's say we have a circle with a radius of exactly that size (or 25 billion miles in diameter) and we want to calculate the circumference, which is pi times the radius times 2. Using pi rounded to the 15th decimal, as I gave above, that comes out to a little more than 78 billion miles. We don't need to be concerned here with exactly what the value is (you can multiply it out if you like) but rather what the error in the value is by not using more digits of pi. In other words, by cutting pi off at the 15th decimal point, we would calculate a circumference for that circle that is very slightly off. It turns out that our calculated circumference of the 25 billion mile diameter circle would be wrong by 1.5 inches. Think about that. We have a circle more than 78 billion miles around, and our calculation of that distance would be off by perhaps less than the length of your little finger. Marc Rayman, director and chief engineer for NASA’s Dawn mission sheds more light into it. "The most distant spacecraft from Earth is Voyager 1. It is about 12.5 billion miles away.

## Submission + - Nvidia GPUs Break Google Chrome's Incognito Mode

An anonymous reader writes: Nvidia GPUs don't clear out memory previously-allocated, and neither does Chrome before releasing memory back to the shared memory pool. If the user would be watching pr0n (for example) via Incognito Mode, close the session, and then open Diablo 3, while the game launches he'd see snapshots of the "private" browsing session in Diablo's loading screen.

Finally, I don't think Unix (any variant) uses apt-get? There might be one but I haven't met it. It has, of course, been a while since I have played with it.

Well, there's Debian GNU/kFreeBSD but that isn't an official Debian architecture just yet (unfortunately).

True. There's also WoSign (which uses the same root CA but is less restricted), but their OCSP-server is in China which will make the first connection a bit slow.
