It just seems to stand to reason that his lungs probably aren't much more capable than those of a normal person of expelling fine silica dust and too much of that would probably still give him silicosis. And as far as we know, he still needs his lungs to absorb oxygen for him to survive.

For that matter, most other highly durable supes in The Boys or Gen V probably have the same weakness. I'm not even sure why DC's Superman wouldn't have the same weakness (at least the Gunn incarnation). But Kimiko is likely an exception since her lungs could just be removed one at a time and they would grow back.

Assuming it's what Clara would have wanted, of course.

I need to fuse some in the near future and I need to figure out what temperatures to use. Does anyone here have much experience with this specifically?

More specifically, I would like to know where the focus of it is and if it is expected to actually be properly symmetrical.

I'm building a benchtop interferometer using a stabilized HeNe laser. To keep costs down, I intend to use older, commercially-produced surplus parts rather than buying newer or custom parts whenever possible.

Which specific older commercially-produced models of beamsplitter should I look for as surplus that should offer appropriate flatness/surface quality and aperture for this type of interferometry?

Thanks.

I've been given a XIIa sword blade. It's 34" long and has a full tang. I've been told it's made of good steel and is heat-treated. But someone ground it down quite a lot to practice shaping and then it was left in a corner neglected for a year or so and it got kind of rusty. Some areas were a bit pitted by the time it was given to me. I've removed the rust and ground it down just far enough to remove the pits. And with that it's down to about 1.68 lbs (0.76kg). I still need to remove a little more material to correct some remaining issues. It will likely be ~1.55-1.6 lbs when that's done. Is the low weight likely to be problematic in terms of it being a functional sword?

I've tried to do research on the question of how much a XIIa sword would typically weigh. While there is a wide range, this one seems like it will be below most of the lowest estimates I've seen.

It seems like it would be okay as long as it's allowed to callous really well before being placed on soil. Right?

Currently I'm considering Lumentum 1100 series laser heads for this as I think they've been used in similar commercially-made inferferometers. But I'm unsure if there's a realistic advantage to using a single-isotope Neon laser like their model 1103H? Is that simply overkill if I'm not working with very large objects (larger than several meters)? If so, would pretty much any laser head in this series be fine for most typical applications of this type of interferometer?

Thanks.

I really only got into keeping San Pedro in the past few months and it's starting to peak over 100°F here. At what point do these start taking damage from the sun and heat? Do I need to invest in shade cloth soon?

P.S.: They're holding out alright so far. I'm just trying to avoid learning a hard lesson if it's unnecessary.

Edit: I should add that all of mine are in pots.

To make it clear what I want, I want to pass the audio from my Windows gaming PC into the microphone input of my main Linux Mint PC so I can hear the audio from games while still leaving my headphones connected to my Linux Mint PC. This will require that Linux Mint be capable of somehow taking the signal from the microphone input and immediately playing it on the audio output through apparently some kind of ultra-advanced technical wizardry.

Using Audacity, I can record audio from the microphone input. When I play it back I can hear it. So I know there's actual input that I could be hearing if passthrough could possibly be set up.

What has been recommended to me over and over again in searches is to set up loopback. Which as I understand it routes desktop audio to the microphone input so it can be recorded. This is absolutely not what I want. But it seems that nearly every person who has ever asked about this has had loopback recommended to them as the solution and somehow most of them seem to think it solved their problem even though it's a completely different thing so that makes no sense. Also the AIs don't seem to understand the difference between loopback and passthrough so it's what they always recommend enabling even though that's probably not at all what I want. This holds true even if I preemptively insult them for recommending it. Sometimes this results in different suggestions about how to enable loopback though.

What I've tried messing with so far:

If I enable "software playthrough of input" on audacity, then it will not enable passthrough and will also not allow recording anything until the setting is turned off. (Wild!)

(in bash) "pactl load-module module-loopback" does not result in audio passthrough.

(in bash) "pw-loopback" (and then leave the terminal open) does not result in audio passthrough.

It seems that some versions of PulseAudio are supposed to have a loopback option. But the version of it I have does not appear to. It also does not appear to have any kind of option that would enable passthrough.

None of the settings in AlsaMixer that supposedly can be used to set up loopback actually seem to enable passthrough. No other options that might actually set up passthrough seem to exist either.

Helvum is completely empty of all devices.

qpwgraph only has 2 midi devices available.

Am I just trying to do something that's impossible in spite of being an obvious valid use case and theoretically easy to implement for someone who is already working on certain key parts of the audio coding for Linux?

What I'm actually interested in is how long of an object I could put in one and hold at a steady temperature because I need to build a thing.

But like did any manufacturer ever make one that's inconveniently or even ridiculously long?

Thanks.
