A 1 gram rock would be “almost nuclear,” yeah, but not planet killing, and most micrometeoroids/cosmic dust is fortunately much smaller than that.

The void drives in OA are a bit crazy in that they’re almost like little pocket dimensions: sub microscopic, maneuverable, “bigger on the inside” like a Tardis, and requiring further nested void bubbles to enter/exit them without destabilizing. They’re more like something Q would use in their civil war. The description may sound closest to ST’s “ship inside warp bubbles,” but mechanically the displacment/halo drives are closer and their attempt at “more physically consistent” ST warp drives, while void ships are at the absolute edge of what’s possibly plausible in physics, assuming all engineering issues go away.

A giant ship at 1/4c is still quite high, yes… it’s also at the point where, under normal physics, you’d have to worry about things like the exhaust plume vaporizing whatever’s behind it.

Alcubierre drive

Exactly! This is what OA is using, albiet a modified version that doesn’t violate causality like the original Albecurie. See the original link and: https://www.orionsarm.com/xcms.php?r=oa-faq&topic=FTL+in+OA

Star Trek engines are something between displacement and halo drives, though with the bubble technically being “internal” and the ship following all relatavistic limitations:

A warp bubble is a region of space time enclosed in a fold, or bubble, of highly curved space. By expanding the space time metric behind the bubble and contracting the metric in front, the bubble can be made to move without the use of propellant mass. The vessel can apparently be coupled to the warp bubble(s) in various ways; by containing the bubbles wholly within the ship, as in the Displacement Drive; in front of the ship, coupled by gravity and/or magnetism, as in the Halo Drive; or entirely enclosing the ship, as in the Void Drive.

Note that no warp bubble has ever been observed traveling at super-luminal speeds. It is thought that such faster-than-light travel is impossible with void bubbles, because of dynamical instability of the warp metric at speeds greater than light and a suspected high flux of Hawking radiation that would turn anything inside a faster-than-light void bubble into a plasma of fundamental particles.

In the Displacement drive configuration, void bubble based drive nodes, operating in either the Alcubierre or Natario configuration, are enclosed within one or more magnetic containment vessels aboard the ship. The drive nodes are magnetically linked to the vessel within the containment volumes and react against it as they move, effectively pushing or pulling the ship across space with no ejection of reaction mass.

Only wormholes are “FTL,” with the catch that they have to be created and transported very carefully with respect to their light horizons (lest a configuration creates closed timelike curves and makes them explode)

ST doesn’t seem to respect relatively anyway, so I guess it doesn’t matter, heh. The physics are different.

For the curious, OA has a pretty extensive, physically plausible theoretical writeups on warp bubbles:

They’re the STL kind, but still, they do seem to require power.

AFIAIK the impulse drives are sub relativistic in Star Trek, right? Or maybe they aren’t, but that seems.

I meant “Linux User Groups” and “volunteer project.”

That’s a sort of perplexing way of saying there are free operating systems with good online support. And paid operating systems with paid support, if that’s what you prefer.

The above is using a lot of technical jargon that might be misleading.

You can get plenty of support for linux just fine. Including here on lemmy. Plenty of computer repair people should know how to do it, you honestly you’re better just talking to people on the internet instead of taking your whole computer to a repair shop. In other words… you’re kinda going in with the wrong mindset.

You can, indeed, pay for support for some linux operating systems. It will be over the internet though.

You don’t really need a computer repair person for a Framework. It’s designed to be trivially repairable: if something breaks, buy the part from their website, unplug it, and change it yourself.

If your operating system breaks, here’s what you do:

• Put anything important on a USB drive. You should always do this anyway.

• Hit “refresh my PC” in Windows. This will reinstall Windows for you.

I’m not directly answering your question because it’s kind of unanswerable. We have no idea if there are local “computer repair people” that can work on Linux (which is what you are talking about); only you would know that based on phoning up people around you where you live. Ask them “do you guys fix Linux stuff?”

You can install Linux yourself easily, and get a system that’s basically not going to get a virus on it anyway. You can even do it and keep windows: it’s not either/or.

How fast is the current?

Is there a flow threshold where he does start moving, and is that threshold relativistic?

Bromite is fantastic if you’re on Android. Anything tangential to that is cut out, and you can add custom lists like you can with the uBlock extension.

I almost want to block this community because it’s just too close to home.

So then I almost starred this.

Turns out I have 19 pages of Lemmy bookmarks in the browser, just from a year. On top of bookmarks scattered across many browsers.

I haven’t looked through them once.

…Shut up. Covers ears.

The right ring hate for climate change is truly remarkable, and spread to my family in recent years.

I honestly don’t get it. Ignoring it is one thing, but viewing it as an actively malicious, hysterical “belief” that should be mocked? Like, if they’re watching a nature documentary and it’s brought up (cause, you know, they’re literally conservationists filming this stuff in real time; how could they not bring it up?), they make these crude, mocking jokes about it.

And I’m talking about doctors and other science believing, educated professionals.

It’s… weird.

And it’s getting worse.

• For LLM hosting, ik_llama.cpp. You can really gigantic models at acceptable speeds with its hybrid CPU/GPU focus, at higher quality/speed than mainline llama.cpp, and it has several built in UIs.

• LanguageTool, for self run grammar/spelling/style checking.

Keep an eye on Open Web UI. I’ve heard rumblings that it’s starting to enshittify.

FYI, A1111 is obsolete. The diffusers or comfy-based backends are way faster, richer, less buggy and support newer things.

I’d recommend UIs that support SVDQuant, in particular.

Check the battery health.

If it was thrashed (like in Uber driving or cold weather or something), and it needs replacing, the car could be basically totaled. Or so I hear with Teslas.

Ghostty has single-instance mode on Linux that shares some resources.

Oh I didn’t know this. I will have to try it sometime.

That’s fine for lightweight usage, but for workflows like mine that involve heavy TUIs and multiple tmux sessions with dozens of windows/panes with big scrollback buffers, it becomes a bottleneck when one or more panes are flooding output from scripts/playbooks/etc.

Yeah, for sure. Different use cases. Hence I can keep both installed, heh.

I am not the expert, but… Complexity?

Sometimes I use Foot instead of Alacritty/Wezterm to save RAM in extreme situations. Foot’s also really nice because it uses a server/client model (again, saving RAM with many terminals), though I don’t know if that’s fundamentally impossible with GPU terminals.

+1

For stuff like editing massive files or huge folders, the least stuttery, fastest IDE for me is… VScode. Jetbrains (last I tried it) is awful.

Code may not use 1MB of RAM or idle dead asleep, but it utilizes the CPU/GPU efficiently.

Now, extensions are the caveat, like any app that supports extensions. Those can bog it down real quick.
