Take a number that wants to get close to zero. Say:

[0] = 1
[1] = .1
[2] = .01
[3] = .001
[...] = [...]

This gets close to zero, yet never will equal zero. Okay so:

arbitrarily close seems to be the accepted term.

infinitely close is the wrong wording?

The function f(n) = 10^(-n) gets "infinitely close" to 0... lol. Using
the "metaphysical formation" of arbitrarily close... ;^)

This makes no sense. "a number" is one number. And numbers don't want
anything.

Strange notation. [0] = 1. Eh? Why not just use a more conventional
notation for a s sequence:

s_0 = 1
s_1 = 0.1
etc.

You can, if you prefer, write it as a function: s(n) = 10^-n (as you do
later).

> This gets close to zero, yet never will equal zero. Okay so:

But it's not a very good one. For example, one could say that

p(n) = 2^n when n is even
p(n) = 2^-n when n is odd

gets arbitrarily close to zero but also arbitrarily far away from zero.

> infinitely close is the wrong wording?

I would not know what you mean if you said that, so I would say it's the
wrong wording. The best wording is to say

lim_{n->oo} s(n) = 0.

which you can read as "the limit, as n tends to infinity, if s(n) is
zero".

Oh. Does the ;^) mean this as all a joke? If so, sorry.

That was designed to raise a laugh or two. I guess it bombed. Yikes!

That's fine with me. I can see it wrt your logic.

The limit of f(n) = 10^(-n) is zero. However, none of the iterates equal
zero. They just get closer and closer to it...

I was thinking that the statement: "how close is infinitely close to
arbitrarily close" would make some people laugh.

Hehe, numbers don't want to get close to zero! For example, 0.000000001 is pretty close to zero,
but is quite happy being a distance 0.000000001 from zero, and has no desire to get any closer! :)

What you have there, laddie, is a /sequence/, which /converges/ to zero...

>

Yes, "arbitrarily close" captures the idea that for any tolerence t, the sequence eventually gets
/and stays/ within that tolerence from the limit 0.

You could think of it as a game: You go first, and must choose a tolerence t greater than zero.
Then its my go, and I must choose a natural number n. If ALL the sequence entries beyond the n'th
entry differ from the claimed limit by less than your t, I win! Else you win...

E.g. if you choose tolerence .001, I will choose n=4. Since [4]=.0001, [5]=.00001, [6], [7]. [8],et
al are all within your given tolerence, I win!

If I can /always/ win the game, the sequence converges to the claimed limit. (Otherwise it doesn't...)

Another example... maybe your sequence above converges to 0.001? No - you start be choosing e.g.
t=0.00000001. Now I'm stuck - as soon as we go past [4] = 0.0001 all further entries will differ
from 0.001 by more than your tolerence. [Conclusion: the sequence does not converge to 0.001, as is
obvious intuitively, but I'm showing how the game works...]

>
> infinitely close is the wrong wording?

Yes, it's not clear what "infinitely close" means - it sounds like it would be a property of two
specific numbers, like 0 and 0.00000000000000001, but that's nonsense - the latter is a fixed
non-zero distance from zero, and of course there are other numbers both closer or further away from
zero.

Using "arbitrarily" better captures the game-like nature of what is intended. I.e. that /first/ a
tolerence t is fixed as a kind of challenge, /then/ we try to find an entry in the sequence such
that that entry and all subsequent entries are within the fixed tolerence. Mathematically this can
be expressed with quantifiers, which capture the order of choices in the game. Something like:

DEF: x[n] --> a iff ∀t>0 ∃n [ if m>n then |x[m] - a| < t ]

Hey, just because C/C++ is very familiar and
there's lots of perceived utility in the non-blocking,
one thing I wondered to ask you about was this
idea of a queue that basically has this sort of
utility.

Queues are usually only iterated once. Yet, sometimes
it's that items get appended and it's a well-formed
sequence that results the message. In this case
then the idea of this "mono-hydra" or "slique",
as about about the hydra with multiple heads
or the deque the doubled-ended queue, here
the idea is that this particular data structure
has its synchronization about setting a mark
and then basically when it scans from the front
then when it results a full sequence, then it
pops all those off while swapping in the new head.

So, the idea of this data structure is a very usual
use case in the buffering or burst queue or whatever
is the reason why a queue is filling up in the
intermediate, until the consumer indicates a
well-formed message and pops that off, while
the producer just atomic-appends items to the tail.

Anyways I wondered in your studies of Single and
Multiple Producer and Consumer, algorithms,
toward the lock-free, if you've considered this
sort simple data structure that I call "monohydra"
or "slique".

It's for something like Internet Protocols where
packets arrive and get assembled, then when they
result a message, that this kind of data structure
is entirely ephemeral, and has no purpose being
in main memory, then for a usual sort of free-list
approach to usual sorts un-even loads.

It's like "how's your chip design going" and
it's like "we solved it by adding burst buffers
between every two units" and it's like "that's
not very systolic".

A usual complement to "how low can you go"
is "how cold can it flow".

Approaching arbitrarily closely seems right to me.

That sort of works too. What you want to avoid is the 'infinite
<something>' which you often say when you mean 'infinitely many
something(s').

I don't know what you are getting at with this.

I will get back to you, a bit busy right now. Actually, I am working on
a neat sort of distributed "queue'ish" work system. It only uses atomic
exchange. When you get some free time to burn, take a deep look at the
following:

I was told one time that infinitely closer is in the realm of
"metaphysical" because of the word infinite. However, the term
arbitrarily close is something others can deal with "better", so to
speak. Make any sense?

If you have any questions comments about it, humm... Perhaps put them in
that comp.lang.c++? Fair enough?

I've been thinking about cooperative multithreading,
basically with cooperative threading with timeouts,
since about 2016 I wrote up this idea about the "re-routine",
which is a sort of outline for cooperative multithreading,
where the idea is that all the calls are idempotent and
memoized, and none return null on success, and their
exceptions are modeled as usual error modes or for flow
of control with exceptions if that's the thing, then the
idea being is that the executor sort of runs the re-routine
and then figures that whenever it gets a null, then it's pending,
so it throws itself out, that when the callback arrives when
there's a response, then it just runs again right through the
re-routine, where of course it's all conditioned on the idempotent
memoized intermediate results, until it completes or errors.

This way it's about the same on the heap the intermediate
memo-ized results as the routine is running, but there's
no stack at all, so, it's not stack-bound, at all.

Of course preemptive multithreading and the thread stack
and context switching is about the greatest sort of thing
when some code isn't well-behaved, or won't yield, here
then for figuring about how basically to implement
cooperative multithreading including timeouts and priority.

Thusly, in the same sort of context as the co-routine, is,
the re-routine, this being for a model of cooperating
multi-threading, at least in a module where it can be
either entirely callback-driven or including timeouts,
and besides the executor can run its own threads in
the stack-bound for ensuring usual throughput in
case whatever re-routine is implemented in blocking
fashion.

This is a sort of idea about where mostly what I
want is that the routine is written as if it were
synchronous and serial and blocking, so it's simple,
then that just the semantics of the adapters or
the extra work on the glue logic, makes it so that
the serial re-routine is written naturally "in the language",
making it all readable and directly up-front and
getting the async semantics out of the way.

That's not really relevant here in this context
about "the mathematical infinite and unbounded",
but it results a sort of "factory industry pattern",
or re-routines, then that the implementation of
routine ends up being as simple as possible and
as close as possible to the language of its predication,
while it's all well-formed and guaranteed its behavior,
that then it can be implemented variously local or remote.

I suppose "cooperative multithreading" isn't for everybody,
but re-routines is a great idea.

Then the idea of the sliques or monohydra is basically
exactly as for the buffering the serving the IO's.
I.e., the idea here is that usually request/response
type things for transits can sort of be related to
what goes through DMA and nonblocking or async I/O,
and scatter/gather and vector I/O, getting things flowing,
right by the little ring through their nose.

Then about the infinite and the infinite limit,
it's called "the infinite limit".

But mathematicians want to know about numbers, for instance how close to
zero the unit fractions come.

Take the function Number of Unit Fractions between (0, and x > 0). It has
the following properties:
(1) An increase from NUF(0) = 0 to NUF(x>0) > 0 cannot happen unless
NUF(x) increases at some x.
(2) NUF(x) cannot increase other than when passing unit fractions at some
x = 1/n.
(3) NUF(x) cannot pass more than one unit fraction at a single point x
because
∀n ∈ ℕ: 1/n =/= 1/(n-1).
(4) This requires a first unit fraction, if all are there in actual
infinity.

It means dark numbers.
The function Number of Unit Fractions between (0, and x) has
the following properties:
(1) An increase from NUF(0) = 0 to NUF(x>0) > 0 cannot happen unless
NUF(x) increases at some x.
(2) NUF(x) cannot increase other than when passing unit fractions at some
x = 1/n.
(3) NUF(x) cannot pass more than one unit fraction at a single point x
because
∀n ∈ ℕ: 1/n =/= 1/(n-1).
(4) This requires a first unit fraction, if all are there in actual
infinity.

Nevertheless actual infinity is limites, for instance 1, 2, 3, ... is
limites by ω.
1/1, 1/2, 1/3, ... is limited by 0.

Correct. Between all numbers you can count and the limit there are dark
numbers.
Take the function Number of Unit Fractions between (0, and x > 0). It has
the following properties:
(1) An increase from NUF(0) = 0 to NUF(x>0) > 0 cannot happen unless
NUF(x) increases at some x.
(2) NUF(x) cannot increase other than when passing unit fractions at some
x = 1/n.
(3) NUF(x) cannot pass more than one unit fraction at a single point x
because
∀n ∈ ℕ: 1/n =/= 1/(n-1).

This requires a first unit fraction, if all are there in actual
infinity. Of course the first unit fractions cannot be seen. They are
dark.

You could say approaching asymtotically.

In other words, "Dark Numbers" are made up numbers that try to patch the
holes in your logic and you define that we can not know anything about
them, and thus nothing can be wrong with them.

Of course, since your premises are just wrong, so is your logic system,
and you are just trying to hold it together with the bubble gum and
bailing wire you call "Darkness"

Or, that such a function can't actually be defined, because it assumes
that there IS a "smallest unit fraction".

Just because you can "define" it in words, doesn't mean that it can
actually exist.

Hey.

The pieces of shit called Vladimir Putin and Alexander Bastrykin
just murdered Alexei Navalny.

Yes Putin is actually Hitler.

Nikolay Kharitonov is morally superior to that piece of shit.

It would please the Chinese if you did that. He would not be

Control over Ukraine’s fertile lands would allow Moscow to “attack”
European farmers, FM Stephane Sejourne has said
https://r%74.com/news/592595-russian-victory-ukraine-economic-shock/

The narrative keeps changing just like it was with attack on Iraq. From
fighting for Ukrainians freedom, to Ukrainian democracy, to European
values, to prevent further attack on Europe, to save American lives having
Ukrainians die for them and now we are fighting to keep Ukrainian vast
fertile fields to ourselves. Just wonder what will be the purpose of
prolonging Ukrainian agony tomorrow...

What he means is the West wants to get its hands on the resources,
therefore proving the wests help has nothing to do with helping the
Ukrainian people but "RESOURCES"....LMAO!

French farmers only future is Russia saving EU from U.S. Blackrock owned
cheap Ukrainian food production

This may be the closest thing we have yet seen to an admission by a
Western official, that what concerns the West is control over Ukrainian
resources, rather than the interests of the Ukrainian people.

Do you (WM) say that
a point with a final.ordinal.reciprocal
⅟n⋅n = 1 ∧ ⟨1,…,n⟩ ⃒⇇ ⟨1,…,n,n⁺¹⟩
below it is infinitelyᵂᴹ.close to 0?
That would be an odd use of "infinite".

A positive dark number has
a final.ordinal.reciprocal below it.

Therefore,
a positive dark number has

Each final.ordinal.reciprocal

The first final.ordinal.reciprocal not.exists.

Impossible,because 0 is not a unit fraction.

No. If 2β fits between two unit fractions this is not true.

yes. Therefore NUF cannot increase at 0.

No, this axiom must be given up.

The alternative would be an increase of NUF(x) to infinity at zero.
Not acceptable.

You have no idea what a NAZI is.

A NAZI or Fascist is.

Someone who thinks that 'martial law' or an 'emergency'
is an excuse to never obey any laws at all.

They make 'war' against anyone or anything they feel
like so they can maintain the 'emergency'. A classic
example is the burning of the German legislature.
Probably Goebbels dunnit, and then Hitler figured
it out slightly later, but the 'emergency' meant
that the NAZIs rapidly murdered most other parties,
then they killed anyone that they felt like including
judges.

Communism is.

Something exactly the same except they use 'politics
and economics' as the excuse.

When they do this they modify 'due process of law' -
the constitution looks exactly the same.

When governments no longer obeys laws then the police
and military shoot the people in general based upon
whim, caprice, and random chance. There are no 'laws'
because there is nothing to separate 'law' from 'crime'.

Now for a long time the Russians were 'Communist' and
in a lot of ways that is the opposite side of the political
spectrum, but in other ways they are nearly identical.

The ways that they are generally identical is called
'totalitinarianism' which is a total tossing of all
laws out the window.

There is some to be said of anarchism. Nine nations
have built nuclear weapons for one purpose. To murder
you, murder me, and every last man, woman and child on
Earth. Hitler never had nuclear weapons. In a lot of
ways this makes many modern governments worse.

And of course stupid people think that nuclear weapons
were not at least partially designed to murder the
people - en masse - to combat what governments might
perversely call 'insurrection'.

People think that in the long run governments are
capable of REFRAINING from pressing the button.

The United Nations should EXPEL all nuclear powers
from UN membershep - forever - and never allow
any to return until they all get rid of their nuclear
weapons. They can each sign - and not implement - until
all have signed. It can be done.

Think about Ukraine. Ukraine was once part of the
Soviet Union. How explicit is it going to get.
Nuclear weapons are explicly to 'combat insurrection'.

Rabid dogs like this should never have these machines.
No one should have them. If the people of the world
could vote - 1. I do want to be murdered with nuclear
weapons. 2. I do NOT want to be murdered with nuclear
weapons - how would they vote? Do you think people
CARE if they are murdered or not? Perhaps NONE of
the nuclear powers are democracies. They cease that
when they build them.

Lines drawn on maps are just one 'special effect' that
excites the rabid dogs.

Yes the war in Ukraine is extremely wasteful.

Yes some type of compromise is possible.

But rabid dogs do not tend to look for compromises.

Russians can never be fascists, right? This is foolishness.

Why vote for a fake Lenin?

If real actual fascism has converted him into a rabid dog then?

You have the power to decide only once every six years.

By now Nikolay Kharitonov may be a lot more of a rational
choice than the fake Lenin.

Some times what is rational, actually has constructive
benefits.
