@freemo sorry, what gradient becomes less at depth? dP/dh = ρg no matter what depth h you have.

@freemo well, not exactly. Going deeper underwater changes the gauge pressure a diver observes, but not the hydrostatic pressure difference between his head and his toes (ΔP=ρgΔh). ρ and g are effectively constant no matter where the diver is, and Δh is just a function of his posture - his height, if he stands upright.

But for the pilot in a non-inertial reference frame, g is not constant. So when he manouevres, the ΔP changes substantially, while the diver will always see about 17.8kPa (182cm diver standing upright in freshwater) higher pressure at his toes than at his head if standing upright.

@freemo that's the idea behind the g-suit: https://en.wikipedia.org/wiki/G-suit

It directs fluid to bladders around the lower body to counteract the ρgh gradient the pilot's blood is subjected to, which means that pooling blood in the legs doesn't represent a low-energy state, which in turn means that blood has less tendency to leave the brain and impair function.

@arteteco enabled Talk on the Nextcloud server not long ago, and it works well for voice, video, and text chat. One could create a "general" conversation, add every user on the server, and start an ongoing call to which anyone could connect as they pleased.

I feel like this should be initiated by an admin - although I could in theory follow this recipe myself, I don't think many users would look favourably on a possibly high-noise chat to which some random account added them.

Here's an XPath rule that can be used in a compatible adblocker. It works, but causes a bit of flickering as the blocked post loads and is removed in a fraction of a second. Of course, if you want it to affect a different website than QOTO, you should change that.

qoto.org##:xpath(//button[contains(concat(' ',normalize-space(@class),' '),' status__content__spoiler-link ') or contains(concat(' ',normalize-space(@class),' '),' spoiler-button__overlay ')]/ancestor::div[contains(concat(' ',normalize-space(@class),' '),' status__wrapper ') or contains(concat(' ',normalize-space(@class),' '),' detailed-status__wrapper ')])

@realcaseyrollins

The original word is ΠΟΡΝΕΙΑ (porneia) which Wiktionary tells me can be either "prostitution" or "fornication".

But even so, that doesn't necessarily indicate that Paul *meant* fornication specifically being immoral, since he was writing in Greek. That's just the way the language was used - one might write "wine" when meaning alcoholic beverages in general, "iron" when referring to weapons in general, and so forth. So even if the word literally means "fornication" it's entirely possible he was using it with the intention that his Greek-speaking readers would take its meaning more broadly.

The translator has to make a decision to render the word's meaning or the author's meaning. If he's writing to an audience that knows these conventions in Greek, he can go with the former and let the audience infer what Paul really meant. But even among educated adults, familiarity with Greek is on the decline, so modern translations are increasingly likely to reword the phrase to preserve the intended meaning as opposed to the literal meaning.

@realcaseyrollins Do you think that's maybe more accurate? I know Greek is *big* on synecdoche, and, if that's the source language, it's appropriate for the translator to choose a phrase that reflects the broader scope intended.

@freemo Thanks! That's close enough - I was trying to see how high the second heavy stroke reached. Looks like roughly the same height as the dot on the i.

I don't really enjoy calligraphy the way I think you do, but I think it's important to write legibly and that looks like a rather more recognisable letterform than the half r I ordinarily use. So I might try incorporating it in my Zaner-based cursive. I already use other styles for a few letters (the Zaner G in particular is contorted to a silly degree).

@freemo do you have a geometry/construction sheet for the full r?

Different teachers preferred or required different styles for other letters but not r in my upbringing. I learned at different times two cursive forms for G and three for x.

@realcaseyrollins@mstdn.social That's not a stretch at all, actually! It's properly a federated model, though, not peer-to-peer. Way back when I started using TextSecure (as Signal was then known) this was indeed nominally the plan. But the lead developer Moxie moved away from it so that he could make breaking changes without disrupting traffic while some servers updated from an old, incompatible version.

@realcaseyrollins@mstdn.social

Is there an architecture for how that would work? Signal runs on mainly mobile devices, which tend to lose connectivity and/or see their IP addresses change frequently. With a server, you can drop off a message and your buddy can retrieve it, and neither of you needs to be able to address the other directly. But once you remove the centralised server, you need some way to know where to send it.

@freemo @2ck That's diag(). You just multiply by the appropriately-shaped unity before Hadamard, i.e. for a column vector x and matrix A, diag(x)⋅A = (x⋅1ᵀ)∘A

@freemo This toy programming challenge never got any nibbles, but I did use linear algebra when I did it - maybe it would scratch that hankering for you?

@realcaseyrollins@mstdn.social I see, thanks!

@realcaseyrollins@mstdn.social Are there notable differences between quodverum, noagendasocial, and freespeechextremist? I mentally bin them together but there might be subtleties I'm not aware of.

@freemo @realcaseyrollins

In the sense that if you visit a post from within QOTO, say, https://spinster.xyz/@TatsuyaIshida/posts/104158509568722634 you only see one reply (even if following the post author). But if you go to the Spinster site, there are more - it's just that any branch of the tree of replies is pruned where the author is a Spinster user you're *not* following.

@freemo @realcaseyrollins My main dissatisfaction with it is that I can (1) follow a user on such a site, (2) click on a post of his, and even after these two active, affirmative-consent things I have done, any reply-threads are cut off once another user I haven't followed comments (i.e. that comment and any children are suppressed). A QOTO user really can't be part of the conversation with even a silence in effect.

@freemo @realcaseyrollins

Forgive me if this is a stupid question, but would there be an obstacle to personally muting the server while leaving it unblocked on the account listed as site admin? Seems to be the best of both worlds - you get to ignore instances as you please, but you can still see the full context if someone reports me in a thread involving users from those instances.

@arteteco @freemo

Working now :)

Thanks very much!

@freemo Trying to set up videoconferencing leaves me with the message, "Nextcloud talk app not installed on the server, aborting"

So, for my part, the request for Jitsi stands, amended with Nextcloud Talk as an alternative.
