As of version 2.1.0,
werkzeug has removed the
as_tuple argument to
Client. Since Flask wraps werkzeug and you're using a version that still passes this argument, it will fail. See the exact change on the GitHub PR here.
You can take one of two paths to solve this:

Dart SDK officially supports ARM64 and as of now, 2.14.2 is the latest (stable) Dart SDK that has support for ARM64. Though it was the same version that was bundled in my Flutter setup, it seemed to run on Intel architecture (Activity monitor shows dart processes running on Intel).
I manually tried replacing the dart SDK on my flutter installation bu replacing
flutter-directory/bin/cache/dart-sdk/ with the contents of a zip file of the Dart SDK made for ARM64, downloaded from dart.dev archive. But trying to run an app on an Android emulator (which runs on ARM64 and was working on my old Flutter setup), throws this error:

It seems it can't be used with Flutter yet, as seen in:
Apple Silicon support in the Dart SDK
[...] Note that the Dart SDK bundled in the Flutter SDK doesn’t have these improvements yet.

[...] As of Flutter 1.21, the Flutter SDK includes the full Dart SDK. So if you have Flutter installed, you might not need to explicitly download the Dart SDK. Consider downloading the Dart SDK if any of the following are true:
- You don’t use Flutter.
- You use a pre-1.21 version of Flutter.
- You want to reduce disk space requirements or download time, and your use case doesn’t require Flutter. For example, you might have a continuous integration (CI) setup that requires Dart but not Flutter.

Unintended consequence of Mark Shannon's change that refactors fast opcode dispatching: https://github.com/python/cpython/commit/4958f5d69dd2bf86866c43491caf72f774ddec97 -- the INPLACE_ADD opcode no longer uses the "slow" dispatch path that checks for interrupts and such.

The logic of comparing files seems alright, I don't find any outstanding problem with it, it is ok to prepend the "/" to match what you need.
Could be even better if you could use the
System.IO.Path.DirectorySeparatorChar for the directory root path as well, so if you run on windows or Linux you will have no issues.
But there may be a conceptual problem with what you are doing. To my understanding you aim to verify existence of specific configuration files required for your program to work right, if those files are missing than the program should fail. But that kind of failure due to missing configuration files, is an expected and valid result of your code. Yet, you unit-test this as if missing files should fail the test, as if missing files are an indication that something wrong with your code, this is wrong.
Missing files are not indication of your code not working correct and Unit-test should not be used as a validator to make sure the files exist prior executing the program, you will likely agree that unit-test is not part of the actual process and it should only aim to test your code and not preconditions, the test should compare an expected result (mock result of your code) vs. actual result and certainly not meant to become part of the code. That unit test looks like a validator that should be in the code.
So unless those files are produced by your specific code (and not the deployment) there is no sense testing that. In such case you need to create a configuration validator code - and your unit test could test that instead. So it will test that the validator expected result with a mock input you provide. But the thing here is that you would know that you only testing the validation logic and not the actual existence of the files.
We are working on a project which allows us to record some sounds from a microphone with a 5k Hz sample rate with some Low-Pass filter & HighPass filter.
What we are using
We are using AvaudioEngine for this purpose.
We are using AVAudioConverter for downgrading the sample rate.
We are using AVAudioUnitEQ for the LowPass & HighPass filter.
ANSWERAnswered 2021-Dec-17 at 10:50
I think the main problem with this code was that the
AVAudioConverter was being created before calling
engine.prepare() which can and will change the
mainMixerNode output format. Aside from that, there was a redundant connection of
outputNode, along with a probably incorrect format -
mainMixerNode is documented to be automatically created and connected to the output node "on demand". The tap also did not need a format.

Short answer: Use a star to collect the arguments in a tuple and then add a special case for a tuple of length one to handle a single iterable argument.
Source material: The C code that handles the logic can be found at: https://github.com/python/cpython/blob/da20d7401de97b425897d3069f71f77b039eb16f/Python/bltinmodule.c#L1708

(Disclaimer: I'm not 100% sure how codatatype works, especially when not referring to terminal algebras).
Consider the "category of types", something like Hask but with whatever adjustment that fits the discussion. Within such a category, it is said that (1) the initial algebras define datatypes, and (2) terminal algebras define codatatypes.
I'm struggling to convince myself of (2).
Consider the functor
T(t) = 1 + a * t. I agree that the initial
T-algebra is well-defined and indeed defines
[a], the list of
a. By definition, the initial
T-algebra is a type
X together with a function
f :: 1+a*X -> X, such that for any other type
Y and function
g :: 1+a*Y -> Y, there is exactly one function
m :: X -> Y such that
m . f = g . T(m) (where
. denotes the function combination operator as in Haskell). With
f interpreted as the list constructor(s),
g the initial value and the step function, and
T(m) the recursion operation, the equation essentially asserts the unique existance of the function
m given any initial value and any step function defined in
g, which necessitates an underlying well-behaved
fold together with the underlying type, the list of
g :: Unit + (a, Nat) -> Nat could be
() -> 0 | (_,n) -> n+1, in which case
m defines the length function, or
g could be
() -> 0 | (_,n) -> 0, then
m defines a constant zero function. An important fact here is that, for whatever
m can always be uniquely defined, just as
fold does not impose any contraint on its arguments and always produce a unique well-defined result.
This does not seem to hold for terminal algebras.
Consider the same functor
T defined above. The definition of the terminal
T-algebra is the same as the initial one, except that
m is now of type
X -> Y and the equation now becomes
m . g = f . T(m). It is said that this should define a potentially infinite list.
I agree that this is sometimes true. For example, when
g :: Unit + (Unit, Int) -> Int is defined as
() -> 0 | (_,n) -> n+1 like before,
m then behaves such that
m(0) = () and
m(n+1) = Cons () m(n). For non-negative
m(n) should be a finite list of units. For any negative
m(n) should be of infinite length. It can be verified that the equation above holds for such
With any of the two following modified definition of
g, however, I don't see any well-defined
g is again
() -> 0 | (_,n) -> n+1 but is of type
g :: Unit + (Bool, Int) -> Int,
m must satisfy that
m(g((b,i))) = Cons b m(g(i)), which means that the result depends on
b. But this is impossible, because
m(g((b,i))) is really just
m(i+1) which has no mentioning of
b whatsoever, so the equation is not well-defined.
g is again of type
g :: Unit + (Unit, Int) -> Int but is defined as the constant zero function
g _ = 0,
m must satisfy that
m(g(())) = Nil and
m(g(((),i))) = Cons () m(g(i)), which are contradictory because their left hand sides are the same, both being
m(0), while the right hand sides are never the same.
In summary, there are
T-algebras that have no morphism into the supposed terminal
T-algebra, which implies that the terminal
T-algebra does not exist. The theoretical modeling of the codatatype Stream (or infinite list), if any, cannot be based on the nonexistant terminal algebra of the functor
T(t) = 1 + a * t.
Many thanks to any hint of any flaw in the story above....
ANSWERAnswered 2021-Nov-26 at 19:57
(2) terminal algebras define codatatypes.
This is not right, codatatypes are terminal coalgebras. For your
T functor, a coalgebra is a type
x together with
f :: x -> T x. A
T-coalgebra morphism between
(x1, f1) and
(x2, f2) is a
g :: x1 -> x2 such that
fmap g . f1 = f2 . g. Using this definition, the terminal
T-algebra defines the possibly infinite lists (so-called "colists"), and the terminality is witnessed by the
