You could make a religion out of this.

It'd be easier to train clamp scientists to static fire than to train rocket scientists to clamp.

wouldn’t changing it just end up performative

Exactly. Sidereal time does get rid of time zones and leap years, but it's still referenced to a single physical object and relies on a arbitrary choice of start point. So it doesn't create some perfect cosmic time standard.

The international date line doesn't help since that's just 180° offset from Greenwich itself.

The point of standards is that they can be followed by everyone. The AD/BC epoch is fine. The Greenwich meridian is fine. UTC is fine. Changing them would cause so much disruption that it cannot be worth it.

Daylight savings can go die in a ditch though.

doesn't change

Citation needed.

Do you use leap seconds to stay in sync with earth's rotation? When would they be applied? How would spacefarers be notified of these updates?

Also, what meridian do you choose for this 'universal' time? Is it still Greenwich? Because that's peak colonial baggage.

I thought one thruster has been permanently disabled now? Not that that's a major problem, but it does eat into their redundancy somewhat.

How will they filter it out? If they just don't mirror anything with 'forbidden' terms, we can poison repos to prevent them being mirrored. If they try to tamper with the repo histories then they'll end up breaking a load of stuff that relies on consistent git hashes.

Starship is about 80% the width of Falcon Heavy - but all the way around and practically all the way up!

That is fun, I didn't know that was a thing. I imagine that roll-overs are more common than submersion in water, but even so, that doesn't sound like a great trade-off. Even in a crash, being able to quickly jump out the window is good — especially if the vehicle is on fire.

The front ones don't seem to be hidden, but yeah - if they're not meant to be used regularly, people won't remember them in an emergency. I guess the rear ones are hidden because they probably bypass child-locks.

I don't know how child-locks work on mechanical door latches. If the vehicle locks when in motion and the child-locks are on I don't think there are emergency releases on most vehicles? The only ways out would be to get into the front cabin, break the windows, or find the internal boot release.

There's a panel that can be popped out to open the hood with a 12V power supply: https://www.tesla.com/ownersmanual/modely/en_us/GUID-34181E3A-B4A7-4658-906A-38C6647B5664.html

Sorry for the crap photos - I just wanted to share these extra keys I added to my Lily58.

I noticed there was a gap in the matrix so I tacked a spare hot-swap socket to the pads on the back of the PCB. That worked with minimal modification to my QMK set-up. I couldn't really use it dangling off some wires so I set out to make an extension that would slot in and be retained by one of the standoffs. I don't have a laser cutter or 3D printer so I just hacked these out of a sheet of ABS plastic following a printed template and glued them up. They're nice and solid and line up really well, despite being rather rough around some of the edges.

I'm finding the 1.5U keys a bit confusing at the moment, swapping them out for 1U keys makes it a bit easier to home my thumbs. These are certainly much easier to access than the outermost keys on the lower row or the keys below the display. I'm thinking they need to be called Lily Pads.

Hi All,
I'm still very new to Nix but trying to daily-drive NixOS.

What I'm currently stuck on is injecting Python packages into a Jupyterlab service. What I have at the moment in the home-manager.home portion of my system flake is the following:

  systemd.user.services.jupyter = let
    jupyter = pkgs.jupyter-all.override {
      python3 = pkgs.python311.withPackages (python-pkgs: with python-pkgs; [
        numpy
        matplotlib
      ]);
    };
  in {
    Service = {
      Type = "simple";
      WorkingDirectory = "${home.homeDirectory}/notebooks";
      ExecStart = "${jupyter}/bin/jupyter-lab --no-browser";
    };
  };

This fires up a JupyterLab process that I can connect to and which runs fine, but numpy etc. can't be imported. From a devshell, I see that the python.withPackages mechanism seems to rely on $PYTHONPATH to pass in a python3-3.11.8-env package that contains a lib/python3.11/site-packages. I'm guessing that the systemd service just needs to have an Environment key, but where do I get the python3-3.11.8-env path from?

The Jupiter executable is in a /nix/store/#-python3-3.11.8-env/bin location, but the site-packages only include the modules for Jupyter so I assume there's another python3-3.11.8-env in the nix-store that does have the python packages I'm trying to get. Trying things like jupyter.env gives errors like *** Python 'env' attributes are intended for interactive nix-shell sessions, not for building! *** but I'm just taking a stab in the dark here.

I'd appreciate any pointers on this. I see there are helpers like JupyEnv, but these seem focused on setting up ephemeral devshells, not running a service for long-term notes and seem like overkill for what I want.

I seem to have gotten a saved account that can't be switched to and therefore can't be removed.

My instance had some server side issues and on PC I had to delete my cookies to get the desktop site to work. Connect wouldn't work and I had to add the account again. At some point the account name has changed to my email address @feddit.uk, which looks weird since it has two @ symbols. The newly added account works fine, but there's this stuck second version of it.

When I try to switch to the broken version I get an error pop up that just says "Error: unable to switch to 'me@email.domain@feddit.uk'" and it seems to retain the currently selected account.

Since I can't switch to that account, I can't sign out to have Connect forget it. So I don't see a way to get rid of it.

Has anyone else run into the same problem? Any suggestions?
