High frequency is generally bad for transmission line losses, so getting power from A to B is better at lower frequency — DC is a great option here.

If we switched to DC, many things would still flicker though as they would presumably use switching power supplies, but those could be relatively high frequency like you said.

Interestingly, airplanes use 400Hz, as transmission over distance doesn’t matter, and transformers can be made much smaller/lighter.

Sounds like this was basically the plot of the first Nolan Batman.

VNC? You have your choice of servers, and clients are ubiquitous.

A big gotcha is that you need to be careful with encryption/security, as in classic UNIX style VNC does one thing (remote desktops). It’s easy to forward over ssh though.

You can also use VNC to share, which is not what you want; this depends on the type of server/settings. But you can definitely create a new virtual X11 session and access it remotely.

Not a historian, but folks on The Internet have characterized the Soviet program as a series of milestones, with the US program a series of stepping stones in support of a single goal.

This makes sense with the cartoon, where the Soviets were first in basically everything except walking on the moon.

Not sure how much merit it has, but it’s kinda interesting.

Resistors.

Mac at work. Yabai+sketchybar is no i3wm replacement, but it works ok.

My .zshrc is basically the same as I use on my personal computers, and aside from a few coreutils differences it…kinda just works. I have apt aliased to brew so I can feel more at home.

Stock terminal works fine—I use xterm on Linux, so I’m used to relying on tmux for nice features anyway.

Basically, I miss the window manager, but practically speaking that’s a about it. (I obviously have xscreensaver installed!)

nc is useful. For example: if you have a disk image downloaded on computer A but want to write it to an SD card on computer B, you can run something like

user@B: nc -l 1234 | pv > /dev/$sdcard

And

user@A: nc B.local 1234 < /path/to/image.img

(I may have syntax messed up–also don’t transfer sensitive information this way!)

Similarly, no need to store a compressed file if you’re going to uncompress it as soon as you download it—just pipe wget or curl to tar or xz or whatever.

I once burnt a CD of a Linux ISO by wgeting directly to cdrecord. It was actually kinda useful because it was on a laptop that was running out of HD space. Luckily the University Internet was fast and the CD was successfully burnt :)

I’m a ~/tmp man myself.

Maybe not a service in the typical sense, but setting up your router+server to route your home network traffic through a VPN is a fun project.

My router (MikroTik) supports WireGuard, so I can use it with Mullvad for the whole house—but wg is demanding and it’s a slow router, so while it can NAT at ~1Gbps, it can’t do WireGuard at more than ~90Mbps. So, I set up WireGuard/Mullvad on a little SBC with a fast processor, and have my router use that instead. Using policy based routing and/or mangling, I can have different VLANs/subnets/individual hosts selectively routed through the VPN.

It’s a fun exercise, not sure I implemented it in a smart way, but it works :)

640k 780k ought to be enough for anybody…

If you can build up intuition around Fourier decomposition I think it gets much easier to understand.

Multiple things going on at the same frequency are indistinguishable (up to a phase). Lots of stuff going on at different frequency can be separated. Light also has frequency (color) and volume (intensity)—it may be more intuitive to conceptualize in this way.

I used Photoprism years ago, so my knowledge is probably pretty outdated.

My experience of Photoprism was that mobile was not tightly integrated. At the time I used Syncthing to sync photos — it worked ok for me, but I wasn’t going to set it up on my partner’s phone, for example.

Immich Just Works on both mobile and desktop. Multi user is great, sharing is great, and the local ML and face detection work remarkably well.

Whatever works for you is the best of course! Immich fits the bill for me, and it was very much worth it for me to “buy” it.

xscreensaver of course! Note that this is not an option on Windows—jwz hates Microsoft, and any xscreensaver port to Windows is against his wishes.

I use yabai and sketchybar for a tiling WM feel. It’s nowhere as nice as my preferred i3, but it’s ok. Unfortunately it often breaks with major OS updates, so I’m sure to hold back updating my system until yabai is working.

IIRC sshfs will work on macOS but it’s more work to install. Worth it if allowed by your IT policies and your work can benefit from it.

Vim, tmux, and the usual *NIX stuff you might want.

The coreutils are not the GNU coreutils you typically find on a Linux system, so you may find a few differences. I believe sed is slightly different, and the flags for ls must be before the filename arguments, but I’ve found it’s mostly silly stuff like that (I used zsh before using macOS, so no problem there).

Regarding DNS servers, what router do you have? Some routers have simple enough DNS capabilities — I have a MikroTik, and have it set up with DNS entries for internal services (including wildcard). Publicly accessible services just use my registrar’s DNS (namecheap — no complaints).

Why are fruit special though? Leaves and roots are also part of a plant, so why would a tomato not be a vegetable, but lettuce (leaf) and carrot (root) get exemptions?

What exactly is a vegetable, by your definition?

As others point out, vegetable is a culinary term; fruit is a botanical and culinary term.

On low end CPUs you can max out the CPU before maxing out network—if you want to get fancy, you can use rsync over an unencrypted remote shell like rsh, but I would only do this if the computers were directly connected to each other by one Ethernet cable.

If you’re running it via docker compose it’s trivial to upgrade, and there are no breaking changes. Pull, down, up, you’re done.

Frigate is pretty good, too. I’ve only been running it for a few months but I’m very happy with it.

Though, technically that leaves you more at risk of ransomeware or something that overwrites your data.

I rsync as well, but use snapshotting on the remote drives. So, a bad rsync would suck but shouldn’t really result in data loss. Ransomware on my local+remote server would of course be very bad…
