Chuck Yeager’s Air Combat would ask for various airplane specs (“what is the service ceiling of an F-4E?,” “what is the ferry range of a MiG-15?”), and you had to flip through a booklet to find the answer.

You could copy the book, but it was fairly long so I guess the friction kept you in check.

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.

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.

I would recommend PoE security cameras. You probably want support for RTSP / ONVIF.

I have some Amcrest cameras talking to Frigate. It is completely local—cameras on a separate VLAN that can’t talk to the Internet, footage is recorded on a server running Frigate. Works very well for me. No vendor lock-in is also nice!

640k 780k ought to be enough for anybody…

If you search around you might find free ones. Oracle has/had a free tier (though it’s Oracle, so…).

Sadly not really. I use the free tier Oracle, which honestly has worked very well, but I’m not going to recommend using Oracle aside to say that it functionally works for me.

If I were to switch I would probably go to racknerd.

Yes, but you can run multiple VPS, from different providers, simultaneously.

What I like is that while it does depend on an external provider, it doesn’t depend on a specific external provider. Any VPS with a public IPv4 would work.

VPS+VPN (WireGuard for me), with Tailscale as an emergency alternative, has worked very well for me. Knock on wood the only outages have been my own fault.

VPS+VPN, this is what I do.

VPS has public IP and runs WireGuard “server”* and a reverse proxy (and fail2ban…). Reverse proxy points to my home computer over the WireGuard link. No open ports on my home router.

For private facing/LAN-only services I just don’t have an entry in the VPS reverse proxy. DNS on the router points everything to my local server, so if at home I access everything directly. To access internal services remotely requires VPN (i.e., WireGuard to the VPS).

Works well; I have a tiny free tier VPS but even so, no complaints.

*Yes I know there are no wg clients or servers, only peers, but it plays a server-likr role.

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).

It’s interesting that, with Python, the reference implementation is the implementation — yeah there’s Jython but really, Python means both the language and a particular interpreter.

Many compiled languages aren’t this way at all — C compilers come from Intel, Microsoft, GNU, LLVM, among others. And even some scripting languages have this diversity — there are multiple JavaScript implementations, for example, and JS is…weird, yes, but afaik can be faster than Python in many cases.

I don’t know what my point is exactly, but Python a) is sloooow, and b) doesn’t really have competition of interpreters. Which is interesting, at least, to me.

Others mentioned virtualization — I have had issues with COW filesystems (btrfs), as COW does not always play nicely with VM drives (extreme fragmentation and very poor performance).

Maybe there’s some interplay between amd64 and x64 architectures.

AMD64 and x64 are the same thing. Do you mean AMD64 and x86? There is definitely interplay there, as AMD64 implements the x86-32 instruction set.

You mentioned ham radio — definitely fun! It’s a process to get into it though, as you need to study/pass an exam, and then you need a radio. Radios range from cheap ($25 or so) in the VHF/UHF (“walkie talkie”-style) to more expensive for an HF rig ($1000 range for 100W HF). If you want to get into low power (“QRP”) it can be much cheaper. You also need a fair amount of space for a good antenna setup…

There are tons of different communication modes, some without a computer and, like you mentioned, some that use computers. wsjtx and fldigi are popular programs.

Good luck!

Newer macOS is not Unix certified.

It’s UNIX 03 compliant https://en.m.wikipedia.org/wiki/Single_UNIX_Specification

One or two Linux distros were (are?) UNIX certified, though.

Haha yeah that was the counter example I was thinking of. I agree completely — you could make a Gentoo from source beginner distro, and I think you could make it reasonably “idiot proof,” but it would still be a bad user experience most likely (too much time spent compiling).
