Sounds like it was a 2 petawatt pulsed laser, with picosecond pulses, so 2kJ/pulse. Staggering amount of power and energy for a pulsed laser!

Note that it's not CW, so the average power will be much, much, much less than the pulsed power. Too lazy to find the rep rate to see average power.

Great shot! I live in SF so I've ridden them


they're fun, but also...they just work. Not as smooth as the new Siemens units that run on the other lines, but they get the job done.

I also really appreciate that they're not a tourist gimmick


they run a real route, and they take the same payment & cost the same as other Muni bus and rail lines.

TIL, thanks! Edited my earlier comment.

Momentum could still be conserved if the velocity is unchanged, but it would mean there's now a lot of kickback once it gets big...

Yeah, the only thing I could imagine would be that image loading/processing uses an optimized library, but a single color is (unlikely but possibly) implemented poorly as a loop over every pixel, with some egregious overhead.

~~Most likely shit post though...~~ See reply, apparently real!

Oh I wasn't complaining, I was making a bad joke (the cartoon is a stalemate).

Ugh, Lemmy is full of stale content.

(Edit: it's a joke. Stalemate/stale content...I chuckled at, and upvoted, the post.)

I've been super happy with it. Knock on wood it's been super reliable. I have a single ZFS drive, take snapshots with various retention policies, nothing fancy.

Another fun thing is to set up a reverse proxy on it as an endpoint for services on your local (home) network which can only be accessed by VPN. For example, my Jellyfin service isn't public facing, but I didn't want e.g. my parents to need to set up WireGuard. So instead they can point their TV to a raspberry pi on their network to access the service


even a first gen RPI can handle Jellyfin reverse proxy over WireGuard for moderate bitrates!

In my experience, the blue (405nm) lasers pointers can far, far exceed the nominal (5mW?) power.

Lenna had her time; Fabio will likewise be replaced. But Lorem Ipsum is immortal.

Remind me again, what color was Obama's scandalous suit?
