scolding hot metal

I like the mental imagery — it’s not scalding hot, no, the metal is actively chastising you.

…the San Francisco gold rush in 1949.

Classic CS major, making an off-by-one(hundred years) error ;)

I have some bad new for you about Linux…

Personally, I think the person who cooks should clean the cookware and the kitchen. The incentives are then aligned, and at least for me, it makes me a much tidier cook.

Also, cooking can be fun, cleaning not so much. Separating cooking/cleaning duties just punishes the person who doesn’t get to cook.

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

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

Maybe in the before times, but with the LA residents’ response to the fascist in chief, I think most of us in San Francisco are honored to share the state, and be confused, with Angelenos.

Just keep the Dodgers in SoCal. This is the Giants’ city.

When I hear the term, I think of the Rainbow cover of the Quatermass song. But that’s just me.

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.

California doesn’t allow “use it or lose it” vacation policies. Vacation rolls over up to a reasonable amount, which apparently isn’t super well defined, but my employers have generally set a limit of 2x annual.

No doubt related to Johnson noise.

PhDs in many fields, particularly the physical sciences, are funded. Lost wages are real of course, but you can often come out the other side without accumulating any debt.

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.

Yeah, but do they like Huey Lewis and the News?

Hey Paulina!

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.

OTOH, if you can afford basic necessities, hobbies are just a rounding error on top of them.

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.

I am becoming increasingly more appreciative of the fact that I have root access to “my” company provided work device.

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.
