I do wonder just how chaotic it would be if a pair of bathrooms performed a karyotype on would-be users and had one room for xy, one room for xx, and refused to admit anyone else.
<Ellied>
AIUI some people would be admitted to one or the other depending on which body part was sampled, some would consistently get the "wrong" one for the gender they present, and some would have it work as most cis people expect

oh, I found Redox OS today. Super cool project.
<Ellied>
Their current live image runs blazin fast in 640x480 on my machine, but unbearably slow at the full 1280x800. I suspect this will improve eventually.
<bofh>
Huh, interesting.
<bofh>
I wonder why the disparity, are they like doing bitblitting in VESA compatibility mode or something silly like that?
<SnoopJeDi>
Ellied, have you encountered NixOS before, btw?
<SnoopJeDi>
I'm only vaguely aware of it, but it seems Kinda Interesting™
<SnoopJeDi>
definitely not enough for me to try it or anything
<Ellied>
SnoopJeDi: I think you've asked me this before, I've read about it but not tried booting it
<SnoopJeDi>
oh yes, I probably have
<Ellied>
I'm deterred for now by the fact that it still uses systemd, which makes it Not Interesting Enough for the time being.

I'm more interested in throwing in my lot with the likes of Void, stuff that uses experimental minimal init daemons

Ellied, one of the most frustrating things in tech to be able to conceive what you want as borderline trivial, but it doesn't exist.
<Ellied>
oh yeah, a cool thing about redox is just how small the image is. I thought dd was breaking and stopping early, but no, it really is 38 megabytes.

gaaaah I keep googling for stuff about computer-to-computer transfer of data with USB 3.X, which I understand is in the spec, and expecting to find people who understand what they're talking about in any way.
<Ellied>
(I am not finding any such people.)
<Ellied>
It's just the same damn canned answer about how USB is strictly host-to-peripheral which is only true of 2.0 and earlier
<Ellied>
"Can I do this?" "No, USB is strictly host-to-peripheral" "ok but I said in my question that I meant 3.0, I think the standard describes this" - what comes next is either "oh well I don't know then so I guess no one supports it" or some complete bullshit about power transfer.
<bofh>
thank, Qboid. Thuboid.
<egg>
bofh: :D
<bofh>
Ellied: so I'm fully willing to believe it's 100% unsupported, tbh.
<bofh>
like this is genuinely the first I've heard of that capability.
<Ellied>
yeah, I think that must be the case
<Ellied>
dammit, I thought USB was finally catching up to RS-232 in that respect.
<Ellied>
you can buy crossover cables on amazon even
<bofh>
so like that's a thing with RS-232 b/c there's no distinction between host and peripheral.
<Ellied>
sure there is, what about DTE and DCE?
e_14159 has quit [Ping timeout: 198 seconds]

bofh, oh my god.
<Ellied>
I guess I don't know why you can't just open a USB port as a virtual terminal and send/recv data asynchronously now that 3.0 brings in dedicated TX/RX lines.
<Ellied>
I get that before, the interface was strictly half-duplex so you had to conform to more restrictive standards about who can talk when
<bofh>
Ellied: wait, it does?
<bofh>
what the fuck, USB3 *isn't* half-duplex?
<Ellied>
uh, I think? It's supposed to at have a full-duplex mode at least
<bofh>
did someone have a sudden attack of sanity?!?
<Ellied>
like, the bitrate listings all have full-duplex and half-duplex mode. In fact, I think half-duplex mode might be a 3.1 feature that's not present in 3.0, which is strictly full, but I might misremember.
<Ellied>
From Wikipedia: "USB 3.0 has transmission speeds of up to 5 Gbit/s, which is about ten times faster than USB 2.0 (480 Mbit/s) even before taking into account the fact that USB 3.0 is full duplex whereas USB 2.0 is half duplex."
<bofh>
what the hell, who suddenly decided to be sane and make USB3 not half-duplex?
<bofh>
SnoopJeDi: yeah that's my reaction too.
<Ellied>
I think 3.1 uses some kind of magic to assign data lanes depending on how the connector is plugged in anyway (there are four differential pairs that can ideally be used independently, so the connector's not truly symmetric) so presumably that mechanism also brings in half-duplex capability while 3.0 just has preassigned RX/TX
<Ellied>
that doesn't actually make sense, you could just have one pair of opposite corners be TX and the other pair RX and never have to switch them
<Ellied>
IAC I do know that 3.1 has a 10 Gbps mode that I think must be half-duplex.
<UmbralRaptor>
SnoopJeDi, bofh: ow. That SCP hit me in the feels.

you can do it with chocolate, after all
<bofh>
Oh, I'm pretty sure that's already done to some extent.
<SnoopJeDi>

Yeah, heh. When I read about IF the first time I was like "welp okay maybe my eating habits aren't totally fuckawful".

that there is weeding, there are» fields of particles », there an

<bofh>
falsity? And who, at last, from all cohort of physicists of the world
<bofh>
will explain, what such"field"? The paradox turns out: the field is, and
<bofh>
its material carriers do not exist! I.e. the field exists out of the
<bofh>

intuition says the answer is T*epsilon_1*(epsilon_0)
<SnoopJeDi>

<rqou>
i did the other problems already
<rqou>
hopefully they're correct :P
* egg|afk|egg
stabs the postfix quantifier
<SnoopJeDi>
rqou, this is outside my recollection but have you already begun by writing (xdot-zdot)=(x-z)dot and integrating?
<rqou>
how does that help?
<SnoopJeDi>
inasmuch as the integral of d(x-z) is (x-z)
<rqou>
so my intuition is that since the change in the derivative is bounded by epsilon_1, then over T amount of time the output should deviate by no more than T*epsilon_1. and then the initial condition deviates by epsilon_0, so multiply all of these together i guess??? and get a bound
<rqou>
but idk if this is correct or not
<egg|afk|egg>
SnoopJeDi's approach sounds sane?
<SnoopJeDi>
I think that's the best mathematical compliment I've ever gotten egg|afk|egg :P
<rqou>
wait, that is just T*epsilon_1
<egg|afk|egg>
you end up with sum of f from t0 to t = (x-z)(t)-(x-z)(t0) = (x-z)(t) - δx0
<egg|afk|egg>
the left hand side thereof being bounded by sum of ε1 from t0 to t = ε1(t-t0), so T ε1 + δx0 >= ε1(t-t0) + δx0 >= (x-z)(t)
<rqou>
hmm, so i don't need to multiply epsilon_1 and epsilon_0?
<egg|afk|egg>
(where t in the above ranges between t0 and t0 + T, and T is positive)
<rqou>
so your bound is tighter
<rqou>
whatever, turning it in :P
<egg|afk|egg>
rqou: why do you want to multiply them?
<egg|afk|egg>
how does that make sense?
<rqou>
mumble mumble idk
<SnoopJeDi>
it's usually most straightforward to try the "obvious" thing and then start cheating with analysis when you hit walls
<SnoopJeDi>
so "I wanna bound [thing]" starts with the thing
<rqou>
wait, f(t) is added to the derivative, zdot
<rqou>
not z
<egg|afk|egg>
rqou: so like what's the calculation that yields their multiplication? you're not supposed to just produce a salad of the symbols in the question :-p
<SnoopJeDi>
you have a bound on f(t) though rqou
<SnoopJeDi>
(which bounds its integral)
<rqou>
hmm but intuitively adding them doesn't seem quite right
<SnoopJeDi>
egg|afk|egg, alas, symbol salad is the rule rather than the exception in American maths :(
<rqou>
if the derivative changes a lot, then a smaller change in the initial condition causes a larger change in the output
<SnoopJeDi>
if you're one of the lucky ones who intuits something about the properties of the symbol-pushing you do in your formative years, you spend another bunch of years undoing the damage...
<rqou>
e.g. intuitively if epsilon_0 on the initial condition is e.g. 1
<egg|afk|egg>
1 what
<SnoopJeDi>
rqou, right, that same logic lets you say \int_t0^{t0+T){f(t)} <= T*ε1
<egg|afk|egg>
you don't need those things to live in a field
<rqou>
hmm now i've confused myself
<egg|afk|egg>
plonk them in a vector space, e.g. say x is a length
<egg|afk|egg>
(and t a time, let's not go too nuts)
<rqou>
but there's still the intuition that the change in the derivative should scale the change in the initial condition
<rqou>
not just be added
<egg|afk|egg>
f(t) is then a speed, bounded by ε1 (a speed, too), ε0 bounds a difference in x and is a length
<rqou>
aaah i see
<egg|afk|egg>
rqou: why
<rqou>
it's a speed
<rqou>
not an acceleration
<SnoopJeDi>
right, you bound the "speed" (f) so you bound how far you could possible have gone
<rqou>
too many dots everywhere
<rqou>
so yes, it seems T*epsilon_1 + epsilon_0 should be sufficient
<rqou>
the reason i've confused myself is that the standard solution has a huge time-varying "state transition matrix" Phi
<rqou>
which is multiplied
<rqou>
so i was thinking "what happened to this multiply operation"
<egg|afk|egg>
the change in the initial condition is just me nudging you, which has no effect on anything (I just declared the origin to be 5 metres further over there)
<rqou>
er, this system isn't LTI though
<egg|afk|egg>
it's kept (the origin is still there after T), but it doesn't get amplified or anything
<rqou>
but wait
<egg|afk|egg>
you getting an additional time-dependent speed f(t), otoh, does change things
<egg|afk|egg>
albeit at most in proportion of the supremum of f and of T
<rqou>
couldn't getting a new initial condition move you from a "moves normally" part of the state space to a "flings you to a bajillion instantly" part of the state space?
<rqou>
because this isn't necessarily LTI
<egg|afk|egg>
SnoopJeDi: did I mention that my mission statement at work is "Positive Ляпунов exponent"
<egg|afk|egg>
rqou: what do you mean by LTI?
<rqou>
linear time invariant
<egg|afk|egg>
what does that mean
<SnoopJeDi>
I'm not familiar egg|afk|egg (I'm the fabled impostor!)
<egg|afk|egg>
rqou: oh, p depends on z, hm
<rqou>
yeah
<egg|afk|egg>
yeah then it's trickier,
<egg|afk|egg>
blarg
<rqou>
so you could have a p that is "if less than 1 then a small negative number, else it's a bajillion"
<rqou>
then if you're at 0.99 you eventually go to 0
<rqou>
but if you're at 1.01 then you end up at a bajillion instantly
<egg|afk|egg>
yeah yeah, the proof above was incorrct, because x'-z' is not f
<egg|afk|egg>
you should have yelled at me
<rqou>
i was thinking that wasn't quite right
<egg|afk|egg>
(it's not -f rather)
<rqou>
but now i realize T*epsilon_1*epsilon_0 isn't right either
<egg|afk|egg>
no that literally makes no sense (try putting some units on it, it's a surface!?
<egg|afk|egg>
)
<rqou>
yeah hmm
<egg|afk|egg>
blarg, do some series expansion on p? how smooth is p
<rqou>
hmm, now i think the answer is maybe T*epsilon_1*(*mumble* *mumble* something about Lipschitz bound on p)+epsilon_0
<egg|afk|egg>
well you certainly need a + ε0 somewhere
<rqou>
no, that can't be right either
<egg|afk|egg>
if ε1 = 0, you still get your ε0
<rqou>
how about (*mumble* *mumble* something about Lipschitz bound on p)*(T*epsilon_1+epsilon_0)
<rqou>
:P
<rqou>
that intuitively seems to work
<egg|afk|egg>
maybe? I don't know, try doing a proper series expansion on p
<egg|afk|egg>
what is meant by "obeys the conditions of the fundamental theorem"
<egg|afk|egg>
which fundamental theorem :-p
<rqou>
p is Lipschitz continuous
<SnoopJeDi>
I think it's a very sloppy way to say "you can integrate this thing"
<egg|afk|egg>
SnoopJeDi: well if it's Lipschitz continuous it's a hell of a lot more than "you can integrate it", even Riemann
<SnoopJeDi>
you're not wrong but I don't have access to magical information egg|afk|egg
<SnoopJeDi>
"fundamental theorem" in such a context rings like FTC -> go nuts with integration in your problem-set
<rqou>
er, to clarify
<egg|afk|egg>
rqou: ok, so the Lipschitzkonstante will appear with some mumbling; do the calculation and it should be fairly clear :-p
<rqou>
p is lipschitz continuous in x and piecewise continuous in t
<rqou>
so the solution to the differential equation exists and is unique
<egg|afk|egg>
"fundamental" you keep using this word, I do not think it means what you think it means
<SnoopJeDi>
gotcha, you have the integrability you need for the time bits, then
<rqou>
it's fundamental for this course at least
<rqou>
which is on linear systems
<egg|afk|egg>
yeah :-p

It sounds like they do it via the twitch integration with special devname-activated commands, so you know who's doing it and when
<SnoopJeDi>
THIS IS NOT HELPING MY LEVEL OF CONCERN
<Iskierka>
I mean arguably the normal twitch integration screws with the game more :p
<Iskierka>
turn on earthquakes, laser trucks, exploding trucks, changed gravity
<SnoopJeDi>
hmm, that's a good point, I guess I'm overreacting with knee-jerk "hooking things up to the internet is aaaaAAAAA"
<Iskierka>
I don't think there's any feed-out other than your active choice to stream it, and not sure what it could really capture anyway. It seems to just be reading "let's see how silly we can make the game go in a popular stream"
<Iskierka>
now they doubled physics speed
<SnoopJeDi>
pretty good kek-mine to mess with a GDQ run
<Iskierka>
If it does require twitch integration I suspect they weren't being super-serious to begin with, but it's certainly entertaining :p

Speedrunners is an evergreen couch game for me
<egg|afk|egg>
Iskierka: wow those green trucks are bright
<bofh>
"couch game"?
<SnoopJeDi>
friends sittin on the couch playing something or other
<SnoopJeDi>
don't do that nearly as much as I'd like to, but the folks I do it with all play that at roughly the same skill level so it's like Mario Kart but fun

!wpn bofh
* Qboid
gives bofh an IEEE 754 wombat
<Ellied>
!g IEEE 754
* egg|afk|egg
takes the square root of the wombat
* egg|afk|egg
takes the nth root of the wombat for n=2
<Ellied>
oh, floating point arithmetic
<egg|afk|egg>
the results have different sign bits
<Ellied>
wait what
<Ellied>
how does that work
<egg|afk|egg>
ask the cat?
<egg|afk|egg>
(or bofh and Fiora but iirc we're all confused by that particular one here)
<Ellied>
whitequark: can you ask your cat about that one for me?
<egg|afk|egg>
oh I didn't know котя did numerics too
<Ellied>
you said to ask the cat, which one did you mean?
<egg|afk|egg>
whitequark: context: sqrt(-0) and rootn(-0, 2) are not the same in IEEE 754-2008 (and sqrt(-0) seems to make little sense as far as bofh and I can tell)
<egg|afk|egg>
whitequark: have you taught котя about floating-point arithmetic yet,
awang has quit [Read error: Connection reset by peer]
