True color (24-bit) at Wikipedia is described in pertinent part as
24 bits almost always uses 8 bits of each of R, G, B. As of 2018
24-bit color depth is used by virtually every computer and phone
display and the vast majority of image storage formats. Almost all
cases where there are 3...
In Michael Atiyah's paper purportedly proving the Riemann hypothesis, he relies heavily on the properties of a certain function $T(s)$, known as the Todd function. My question is, what is the definition of $T(s)$?
Atiyah states that this function is defined in his paper "The Fine Structure Cons...
Store a character in any variable.
Rules:
Only python allowed.
Must work on any platform.
Program should ask for input but not wait for \n.
If input char is number, var type should be int. For everything else var type should be string.
I have an array:
[1,0,2,0,3,4]
I want to find the longest non-consecutive increasing sublist, i.e. in this case it is [1,2,3,4] (values) or [0,2,4,5] (indexes).
Héctor, I think this one is for the blogs, if anyone wants to take it up. Atiyah has done some of the greatest mathematics in the past 50+ years, but it looks very likely that here he's "not even wrong", and it is for this very reason that he should be accorded some dignity in view of his epoch-making past work -- not a public raking at MO. That's just my opinion. — Todd Trimble ♦13 hours ago
but that aside, it relies on a mysterious function $T$ having those properties he claims
@Fatalize so the thing is that his proof relies on a mysterious function $T$ defined in one of his other (new) papers about the fine structure constant. The fine structure constant is about physics so I have no idea about that.
And I can't really follow any of the logic in the excerpt of his preprint I quoted
he mentioned something about linear approximation, so 2.7 is just a linear approximation (sqrt(1+s) = 1+s/2)?
how does taking f=g=F in 2.6 allow us to deduce 3.3: F(s) = 2F(s)?
is it just another of his linear approximations?
so his proof is basically "314159 is approximately 310000 which is approximately 300000 which is approximately 0"?
"his energy and ability to control much more than just the bladder at the age of 89+, but the proof of the Riemann Hypothesis will require more than that"
I've noticed quite a few suspicions among mathematicians regarding Atiyah's purported proof. I can understand that.
I've also noticed a certain desdain about Atiyah's himself or his recent work. A feeling of "let's not even talk about this, to avod further embarrassment". That's where I get lost. What's the matter? Is it that Atiyah is not as good as he used to be, perhaps because of his age? Did he do something to earn that apparent disrespect?
@LuisMendo Wrong doesn't even really begin to cover it. His recent work (like the 6-sphere debacle) is too meandering and nonsensical to even really be called wrong.

He almost certainly has some form of age-related dementia
I have a quite different issue to be solved. I am gathering some data from user input which I can arrange into a matrix. An example matrix below.
A little brief about the data and validation rules:
There are 4 number of rows and 5 number of columns in the above matrix. Columns are fixed. Row...
hey, I've got a really weird tech problem: Everything that is built on chromium can't connect to the internet. For example, Chrome, Vivaldi, even electron apps can't connect.
I'm not really expecting a solution in chat, but just baffled by how weird my problem is
@dzaima that's not disallowed though. I left it like that for this exact purpose, so that people would be free to use any kind of border and trace they feel like. The only constraints I put is that you can't use the same character for the trace and the object, and that the borders must visually match each other
@dzaima I did add an explanation as to what I meant with that. Should I add an example of what is allowed and what isn't?
@J.Sallé I know it's not disallowed, but I know I'd reread the challenge twice trying to find where it tells me to use fancy characters to no avail :p
@J.Sallé "visually match each other" is very vague. Would this be allowed? How about this?
A human is able to tell what's okay and what's not, but when golfing is required, everything can be abused to max (though I'd be surprised if everything didn't use either constant borders or built-ins :p)
Haven't looked at that challenge for a while but a stray upvote brought my attention back. I have an improved version with Bezier curves instead of sharp corners that I never got around to posting. Will see if I can find it at some point
I've found Firefox more reliable than Chromium recently for large memory loads (if that's relevant). Firefox handles a tab using (deliberately) 8GB just fine, whereas Chromium crashes after a day or so of that. Not sure if my code is the problem but it doesn't hurt Firefox if so
Bah, there's exactly 1 keyboard shortcut that I have hard-wired into my finger that no other browser does: I can type "you<TAB>keyword" to search youtube, or "cod<TAB>keyword" to search codegolf.stackexchange.com. That TAB is a really hard habit to break
@trichoplax Actually, I'm dumb. Ignore me. Is:q is just all questions closed or open. deleted:1 gives waaaaay more so there's no way that all questions deleted or not are under 10K
deleted:1 only gives lots of results if you're a site mod - otherwise it only lists your own deleted posts (unless there's a rep threshold I need before I see more?)
so, this all comes to rendering engine, right? For some reason the text is a slightly different size, which causes the text to appear slightly different
@trichoplax or in. All that matters is changing the zoom level
Or they could be the same size but measured differently - some operating systems adjust standard measurements for high definition screens, so your browser can treat it like a lower resolution screen. I don't know the technical terms...
Is it possible both ways of measuring are available and the two browsers access different ones?
Chinese police are forcing whole cities to install an Android spyware app Jingwang Weishi. They are stopping people in the street and detaining those who refuse to install it.
Knowing that I may be forced to install it sooner or later, what are my options to prepare against it?

@WW Wait ... I think the pattern is not as simple as it seems ... The signs appear to flip and only on odd inputs is the last -n not part of the output ...
