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.
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.
Oh I wasn't complaining, I was making a bad joke (the cartoon is a stalemate).
One of the coolest parts of The Expanse IMHO was that The Mormons commissioned a giant space ship, and it didn't feel forced or far-fetched.
Ugh, Lemmy is full of stale content.
(Edit: it's a joke. Stalemate/stale content...I chuckled at, and upvoted, the post.)
I've been super happy with it. Knock on wood it's been super reliable. I have a single ZFS drive, take snapshots with various retention policies, nothing fancy.
Another fun thing is to set up a reverse proxy on it as an endpoint for services on your local (home) network which can only be accessed by VPN. For example, my Jellyfin service isn't public facing, but I didn't want e.g. my parents to need to set up WireGuard. So instead they can point their TV to a raspberry pi on their network to access the service --- even a first gen RPI can handle Jellyfin reverse proxy over WireGuard for moderate bitrates!
In my experience, the blue (405nm) lasers pointers can far, far exceed the nominal (5mW?) power.
Remind me again, what color was Obama's scandalous suit?
Ah, right, that's why it looked familiar --- pretty sure I've seen articles from there posted in one of The Onion communities in lemmy.
I'm not mad at the huge amount I pay in taxes. I'm mad about what I get in return.
Only disagreement from me (in California, USA) is that I wouldn't diminish the actions of our neighbors to the north by calling them "petty" in this instance. Nothing petty about standing up to a bully in whatever capacity you can. 🫡
As far as I can tell the "mostly true" (rather than true full stop) is this:
"The federal government does not have a separate, dedicated revenue stream exclusively for disaster aid," said Joel Tirado, an institute spokesperson. "FEMA funding comes from general revenue aggregated nationally. So, it isn’t possible to know how much of California’s taxes go to disaster relief specifically."
So basically, money is fungible, and we (CA) send the most money (absolutely, though not per capita).
WireGuard, and an external HDD. Run at a remote location for off-site backup.
I do this with a raspberry pi 3 at the in-laws. I copied the data over locally before setting it up, and after that it's just nightly incremental rsync, which is fine even over my slow (35Mbps) upload.
You can turn it off, at least for ext4: https://lwn.net/Articles/784041/
Although you can use case insensitive filesystems with Linux, and case sensitive filesystems with macOS. I believe the case sensitivity is a function of the specific filesystem --- but yeah, practically, the root for Linux is always case sensitive, and APFS ain't is only if you ask it to be ( https://support.apple.com/lv-lv/guide/disk-utility/dsku19ed921c/mac ).
You know you fucked up real good when Mr. Oatmeal gets involved.
In undergrad I took a class on sleep, and it really stuck with me. I previously had some FOMO-esque aversion to going to bed early, but after that class if I was done with the day and I was tired, I just went to sleep.
It's been a good mentality for us now that we have a small kid, too. No shame in going to bed at 8...
No, that's not really a useful way of modeling it for the case of light traveling through a linear medium.
The absorption/re-emission model implicitly localizes the photons, which is problematic --- think about it in an uncertainty principle (or diffraction limit) picture: it implies that the momentum is highly uncertain, which means that the light would get absorbed but re-emitted in every direction, which doesn't happen. So instead you can make arguments about it being a delocalized photon and being absorbed and re-emitted coherently across the material, but this isn't really the same thing as the "ping pong balls stopping and starting again" model.
Another problem is to ask why the light doesn't change color in a (linear) medium --- because if it's getting absorbed and re-emitted, and is not hitting a nice absorption line, why wouldn't it change energy by exchanging with the environment/other degrees of freedom? (The answer is it does do this --- it's called Raman scattering, but that is generally a very weak effect.)
The absorption/emission picture does work for things like fluorescence. But Maxwell's equations, the Schrödinger equation, QED --- these are wave equations.
I think it depends on who's doing the talking --- oil execs aren't idiots, so I think in their case, it's the first two (intentional misrepresentation, bad faith).
Someone repeating what their uncle/Newsmax host/etc. said? Yeah, maybe that's the latter...
