Microseconds even! Light travels about 0.3 meter in a nanosecond, and the Eiffel tower has a height of ~300 meter, so it takes about a microsecond for light to get from the ground to the top.

> New Horizons nearly did. New Horizons didn't nearly overtake Voyager. It's currently traveling about 4 km/s slower, and as it's still closer to the Sun, it's also decelerating more.

New Horizons was launched in 2006, and it will reach the same distance from the Sun as Voyager 1 is _currently_ in about 32 years.

Falcon 9 also lands using 3 engines on its most demanding missions. The throttling is definitely an advantage.

It is a rocket. The biggest difference with the Falcon 9 first stage is that this one is about 6 times as big (diameter of 9m vs 3.7m), and that catching it with the tower requires a much higher precision in landing location. The drone ship

That only holds if you believe that will (intrinsic or resulting from a cost/benefit analysis) is what's holding back organizations from improving their cybersecurity.

That's a false dichotomy. Having a few smart kids hack around doesn't end nation state attacks.

I guess you could have an integration test that validates that your installer puts the man pages in a directory that man searches in? It's a bit far-fetched but also not entirely outlandish.

Requiring a timezone seems sensible to me, but I don't understand the choice to make it a required part of the expression, instead of a separate parameter. Most software specifies the timezone separately from the expression (e.g. k8s h

Your computer doesn't actually know what the keys for WASD are. It just receives a number (commonly called scan code) for the pressed key from the keyboard, and has to use the mapping to determine which key that actually was. There&#x2

They don't know all the data that's being hashed, though. They know everything that's in the map, but not all the keys they're trying to lookup.

Instead of writing out "no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty" in the authorized_keys file; you can use the "restrict" keyword to enable all current and future restrictions.

In your comparison, we follow 11:00 PM with 12:00 PM, not 12:00 AM.
