I switched from raspberry pi and orange pi to a cheap Intel NUC, and I think it's just a much nicer experience.

The pi is great fun, but the HW transcoding on a NUC "just works," and the SSD and 16GB RAM opens a lot of doors. My N100 NUC was less than $150, and it included everything (case, power supply, 500GB SSD).

My pi found new life as an off-site backup: attach a big HDD, set up WireGuard, and have a cronjob do daily rsync and snapshots. I have it set up at in-laws, and it works great.

I have one SSID with pihole (which I use), and one without. Works pretty well, if you're ok with a VLAN-aware network.

Ah, good point!

Dell XPS 13 Snapdragon seems like it's trying to compete with the Air.

My comment from cross post:

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.

It's on https://www.thefarside.com/ today as one of the "Selections of classic The Far Side comics." Comic says ©1984, but doesn't give a specific date (an image on reddit suggests 4/6/84).

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.

I recently started using voice (SSB) on the HF ham bands, and have made contacts on 15, 17, 20, and 40m. No real DX, but made one foreign contact ~1000mi away and another domestic ~2000mi away.

I live in a city and it's challenging to get a good antenna setup, so it's always a compromise where I am.

Nothing very impressive by ham standards, but it's fun.

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...
