Temperatures in Starship’s engines can reach up to 3,000 degrees Celsius, requiring batteries that can withstand intense heat without losing performance.
I'm no rocket scientist but I'd put the batteries somewhere other than in the engines.
Still, they presumably have to operate in vacuum so thermals will be a challenge. The vibration at launch must also be pretty gnarly.
I remember doing this with dbus but I can't find that set-up anymore. This stackoverflow answer looks a bit more elegant: https://unix.stackexchange.com/a/128007/37570
A little script could run your command when matching the jack/headphone events from acpi_listen.
I think that's a pretty wild take given the state of NASA right now. The only way I could see anything like that happening would be the GPS model, where the DoD build out StarShield for military purposes, then realise it'd be a net good for civilians to have ubiquitus global internet services. Even then, that would compete with existing non-SpaceX services which is antithetical to NASAs principles and would be considered 'socialism' by half of America.
Asteroid mining is really in the hands of governments. While space is basically a free-for-all on an international level, each nation can levy whatever conditions and taxes they like on their own enterprise. If companies tried to 'flag' themselves with low-tax nations, then I think other nations could levy tariffs and prevent access to technology to make that unattractive. Either way, a significant portion should end up in government budgets.
I'd rather private equity invest in more forward looking technology than LLMs or finance. There just needs to be a balance where it's still attractive for them to invest, but as much of the value as reasonable gets distributed in lifting up the quality of life here on earth.
“abbabba”
“abbabba” doesn't match the original regex but “abbaabba” does
Where are those numbers from? I don't doubt them but it seems a bit weird that even the lowest outlier of these big aerospace companies is still above average for the industry. I guess this is just saying that smaller companies have even more difficulty hiring/retaining female workforce.

Edit: Unless this is a joke about it being made by Sharp, not Tandy?
Here's the requisite Manley analysis of the GEM 63XL SRB anomaly on today's Vulcan certification flight.
Yeah, NSF are pulling in other angles and it definitely blows chunks and yaws slightly. Centaur burn went long - I wonder if that impacts the second burn.
Meanwhile ULA: "Everything performing nominally"
Actually rewatching it, it looks like might have been a nozzle failure on one of the GEMs. There's a big flare before clouds obscure the rocket - much bigger than the ice. After this, one side looks to have a bigger exhaust plume than the other, and burns out slightly sooner.
Yeah, NSF are speculating about it.
In space now. Chilling second stage.
Launch looked a bit chunky but I guess that's just the solids.
If it doesn't have reticulated splines; I'm out.
Have you tried sfc /scannow?
It's Cannonical. They prefer implementing everything themselves fast, rather than developing a more sustainable project with the rest of the community over a longer timescale. When they do that, there will be very little buy-in from the wider community.
Others could technically implement another snap store for their own distro, but they'd have to build a lot of the backend that Cannonical didn't release. It's easier to use Flatpak or AppImage or whatever rather than hitch themselves onto Cannonicals's homegrown solution that might get abandoned down the line like Mir or Ubuntu Touch.

As you say - why would others put time into the less supported system? Better alternatives exist. If Canonical want their own software ecosystem, they'll have to maintain it themselves. Which, based on Mir and Ubuntu Touch, they don't have a good track record of.
I'm upset that a meme I tried to remake with Unicode box drawing characters lines up terribly in apps: https://lemmy.ca/post/28490027 Shouldn't code blocks render in monospace?
On Lemmy's web frontend it's perfect: !
On Connect it looks like this: !
On Jerboa it's basically the same: !
Eternity does use monospace but the box drawing characters seem to be too wide.
All I can find about it here is one post from a year ago: https://lemmy.ca/post/1492857

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?
