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).

You’re right, for new drives it looks like a little more with this 20GB retailing for $230, or $11.50/TB.

For refurbished, I recently got a factory renewed 12TB Seagate for $112 ($9.33/TB), but that price is now up to $199 for the same drive (!).

Official numbers here https://www.debian.org/mirror/size

About 4.4TB, but that’s all architectures and (I believe?) all distributions (stable, testing…).

If you only want source+all+amd64+arm64, and only want stable, it will be smaller of course.

Not nothing, but at $10/TB or so, it’s not much.

And if you’re following 3-2-1, I’m pretty sure the “1” is already handled for you :)

I’ve been really impressed with Immich, can’t recommend it enough.

I’d put substitute first, but yours sounds better :)

(I’m a big Immich fan, and I’m taking and sharing photos more than ever before, in part because Immich is awesome, self hosted, and open source [the other part is that I have kids now so I’m taking way more photos that grandparents want to see].)

Not sure I agree.

First, stocks tend to be highly correlated with “the market” (see financial “β”/“beta coefficient”). For example, look at, say, The Home Depot or Ford Motors. From January 2000 to January 2003 (spanning the dot com bubble) they each lost about a third of their value, yet these are not “dot com”-centric companies.

Second, the promise of AI is that it will help every company that has desk jobs. So every company has this expectation now priced into their stock, and if the bottom falls out, well…

Not an analyst/I don’t pick stocks, but just my 2¢.

Some would call the former command cat abuse.

In short, unless you want the contents of a file printed to stdout (or multiple files concatenated), the command can probably be written without cat, instead using the filename as an argument (grep pattern file) or IO redirection (cmd < file).

Stylistics and readability are another thing though.

I have some bad new for you about Linux…

Yabai+sketchybar make tiling+virtual desktops…at least usable on mac.

Of course, I’d take i3 any day of the week.

Coming from Debian, it was…not expected. I understand how and why it happened, but the user experience was surprising.

Debian keeps the previous kernel around, which makes perfect sense to me — in the event that a kernel update borks your system you can just load the previous one. This would probably only happen due to out of tree modules (looking at you, Nvidia…).

Linux distros can still do…questionable things. In grad school I tried Arch for a bit, and I once was late to a video call because I had updated my kernel but did not reboot. Arch decided that because there was a new kernel installed, I didn’t need the modules for the old — but currently running! — kernel, so it removed them. So when I plugged in a webcam, the webcam module was nowhere to be found.

But yeah…somehow, still not as bad as Windows updates.

Our Internet went out for a few hours today, so naturally my smart switches, lights, cameras, motion sensors, door sensors, and power monitoring… continued to work as of nothing was wrong.

Home Assistant is great, and using local-only devices is awesome. If my smart home stops working it’s my own fault, not some 3rd party.

Your numbers seem reasonable — more intuitive for me to work in terms of pressure. Atmosphere is (roughly) 1e3 Torr, good UHV can be around 1e-10, so that’s 13 orders of magnitude, which is (roughly) the same difference that you calculated.

Aluminum foil is very common in physics labs. And a main use for it is “baking”! To get ultra high vacuum (UHV)* you generally need to “bake out” your chamber while you pump down. Foil is used same as with baking food — keep the heat in and evenly distributed on the chamber.

Sadly, it’s usually not food grade aluminum foil, as that can contain oils, and oils and vacuum are generally a big no-no.

*Just how good is UHV? Roughly: I live in San Francisco, which is ~7 miles by ~7 miles (~11km). Imagine you raise that by another 7 miles to make a cube. Now, evacuate every last molecule of gas out of it. Now take a family sedan’s trunk, fill it with 1 atmosphere of gas, and release that into the 7 mile cube. That’s roughly UHV pressure.

From TFA:

“I have failed you completely and catastrophically,” Gemini CLI output stated. “My review of the commands confirms my gross incompetence.”

Most Linux filesystems, being case sensitive, won’t find the SUDO command.

Yep, you’re right — I was just responding to parent’s comment about fiber being best because nothing is faster than light :)

That’s…not really a cogent argument.

Satellites connect to ground using radio/microwave (or even laser), all of which are electromagnetic radiation and travel at the speed of light (in vacuum).

Light in a fiber travels much more slowly than in vacuum — light in fiber travels at around 67% the speed of light in vacuum (depends on the fiber). In contrast, signals through cat7 twisted pair (Ethernet) can be north of 75%, and coaxial cable can be north of 80% (even higher for air dielectric). Note that these are all carrying electromagnetic waves, they’re just a) not in free space and b) generally not optical frequency, so we don’t call them light, but they are still governed by the same equations and limitations.

If you want to get signals from point A to point B fastest (lowest latency), you don’t use fiber, you probably use microwaves: https://arstechnica.com/information-technology/2016/11/private-microwave-networks-financial-hft/

Finally, the reason fiber is so good is complicated, but has to do with the fact that “physics bandwidth” tends to care about fractional bandwidth (“delta frequency divided by frequency”), whereas “information bandwidth” cares about absolute bandwidth (“delta frequency”), all else being equal (looking at you, SNR). Fiber uses optical frequencies, which can be hundreds of THz — so a tiny fractional bandwidth is a huge absolute bandwidth.
