QUESTION
I saw a video about speed of loops in python, where it was explained that doing sum(range(N))
is much faster than manually looping through range
and adding the variables together, since the former runs in C due to built-in functions being used, while in the latter the summation is done in (slow) python. I was curious what happens when adding numpy
to the mix. As I expected np.sum(np.arange(N))
is the fastest, but sum(np.arange(N))
and np.sum(range(N))
are even slower than doing the naive for loop.
Why is this?
Here's the script I used to test, some comments about the supposed cause of slowing done where I know (taken mostly from the video) and the results I got on my machine (python 3.10.0, numpy 1.21.2):

I'm playing around with go generics by modifying a library I created for working with slices. I have a Difference
function which accepts slices and returns a list of unique elements only found in one of the slices.
I modified the function to use generics and I'm trying to write unit tests with different types (e.g. strings and ints) but am having trouble with the union type. Here's what I have, now:
...ANSWER
Answered 2021-Oct-29 at 19:33I've passed your code through gotip that uses a more evolved implementation of the proposal and it does not complain about that part of the code, so I would assume that the problem is with the go2go initial implementation.
Please note that your implementation will not work since you can definitely use parametric interfaces in type assertion expressions, but you can't use interfaces with type lists as you are doing in testDifference[intOrString]
QUESTION
A simple question: is enum { a } e = 1;
valid?
In other words: does assigning a value, which isn't present in the set of values of enumeration constants, lead to well-defined behavior?
Demo:
...ANSWER
Answered 2022-Feb-05 at 14:09From the C18 standard in 6.7.2.2:
Each enumerated type shall be compatible with char, a signed integer type, or an unsigned integer type. The choice of type is implementation-defined, but shall be capable of representing the values of all the members of the enumeration.
So yes enum { a } e = 1;
is valid. e
is a 'integer' type so it can take the value 1
. The fact that 1
is not present as an enumeration value is no issue.
The enumeration members only give handy identifiers for some of possible values.

Answered 2022-Feb-09 at 07:17References can't bind to objects with different type directly. Given const int& s = u;
, u
is implicitly converted to int
firstly, which is a temporary, a brand-new object and then s
binds to the temporary int
. (Lvalue-references to const
(and rvalue-references) could bind to temporaries.) The lifetime of the temporary is prolonged to the lifetime of s
, i.e. it'll be destroyed when get out of main
.

Answered 2022-Jan-11 at 17:06It looks like you have defined custom paths in your TypeScript config (usually tsconfig.json

I've downloaded Android Studio from the official website, the one for M1 chip (arm).
Basically running it for the first time, the error is the following:
...ANSWER
Answered 2021-Nov-07 at 09:40This is what solved it for me on my M1.
- Go to Android Studio Preview and download the latest Canary build for Apple chip (Chipmunk). Don't worry this is just to get through the initial setup.
- Unpack it, run it, let it install all the SDK components, accept licenses, etc as usual.
- Once it's done, simply close it and delete it.
Now when you start your stable Android Studio (Arctic Fox) you should not see the error.
QUESTION
The standard defines several 'happens before' relations that extend the good old 'sequenced before' over multiple threads:
[intro.races]
11 An evaluation A simply happens before an evaluation B if either
(11.1) — A is sequenced before B, or
(11.2) — A synchronizes with B, or
(11.3) — A simply happens before X and X simply happens before B.[Note 10: In the absence of consume operations, the happens before and simply happens before relations are identical. — end note]
12 An evaluation A strongly happens before an evaluation D if, either
(12.1) — A is sequenced before D, or
(12.2) — A synchronizes with D, and both A and D are sequentially consistent atomic operations ([atomics.order]), or
(12.3) — there are evaluations B and C such that A is sequenced before B, B simply happens before C, and C is sequenced before D, or
(12.4) — there is an evaluation B such that A strongly happens before B, and B strongly happens before D.[Note 11: Informally, if A strongly happens before B, then A appears to be evaluated before B in all contexts. Strongly happens before excludes consume operations. — end note]
(bold mine)
The difference between the two seems very subtle. 'Strongly happens before' is never true for matching pairs or release-acquire operations (unless both are seq-cst), but it still respects release-acquire syncronization in a way, since operations sequenced before a release 'strongly happen before' the operations sequenced after the matching acquire.
Why does this difference matter?
'Strongly happens before' was introduced in C++20, and pre-C++20, 'simply happens before' used to be called 'strongly happens before'. Why was it introduced?
[atomics.order]/4
says that the total order of all seq-cst operations is consistent with 'strongly happens before'.
Does it mean that it's not consistent with 'simply happens before'? If so, why not?
I'm ignoring the plain 'happens before', because it differs from 'simply happens before' only in its handling of memory_order_consume
, the use of which is temporarily discouraged, since apparently most (all?) major compilers treat it as memory_order_acquire
.
I've already seen this Q&A, but it doesn't explain why 'strongly happens before' exists, and doesn't fully address what it means (it just states that it doesn't respect release-acquire syncronization, which isn't completely the case).
Found the proposal that introduced 'simply happens before'.
I don't fully understand it, but it explains following:
- 'Strongly happens before' is a weakened version of 'simply happens before'.
- The difference is only observable when seq-cst is mixed with aqc-rel on the same variable (I think, it means when an acquire load reads a value from a seq-cst store, or when an seq-cst load reads a value from a release store). But the exact effects of mixing the two are still unclear to me.
ANSWER
Answered 2022-Jan-02 at 18:21Here's my current understanding, which could be incomplete or incorrect. A verification would be appreciated.
C++20 renamed strongly happens before
to simply happens before
, and introduced a new, more relaxed definition for strongly happens before
, which imposes less ordering.
Simply happens before
is used to reason about the presence of data races in your code. (Actually that would be the plain 'happens before', but the two are equivalent in absence of consume operations, the use of which is discouraged by the standard, since most (all?) major compilers treat them as acquires.)
The weaker strongly happens before
is used to reason about the global order of seq-cst operations.
This change was introduced in proposal P0668R5: Revising the C++ memory model, which is based on the paper Repairing Sequential Consistency in C/C++11 by Lahav et al (which I didn't fully read).
The proposal explains why the change was made. Long story short, the way most compilers implement atomics on Power and ARM architectures turned out to be non-conformant in rare edge cases, and fixing the compilers had a performance cost, so they fixed the standard instead.
The change only affects you if you mix seq-cst operations with acquire-release operations on the same atomic variable (i.e. if an acquire operation reads a value from a seq-cst store, or a seq-cst operation reads a value from a release store).
If you don't mix operations in this manner, then you're not affected (i.e. can treat simply happens before
and strongly happens before
as equivalent).
The gist of the change is that the synchronization between a seq-cst operation and the corresponding acquire/release operation no longer affects the position of this specific seq-cst operation in the global seq-cst order, but the synchronization itself is still there.
This makes the seq-cst order for such seq-cst operations very moot, see below.
The proposal presents following example, and I'll try to explain my understanding of it:

...ANSWER
Answered 2021-Dec-16 at 21:11I'm a bit confused as how FFMPEG handles diverse framerates
It doesn't, which would cause a misalignment in your case. The vast majority of filters (any which deal with multiple sources and make use of frames, essentially), including the Concatenate filter require that be the sources have the same framerate.
For the concat filter to work, the inputs have to be of the same frame dimensions (e.g., 1920⨉1080 pixels) and should have the same framerate.
(emphasis added)
The documentation also adds:
Therefore, you may at least have to add a scale or scale2ref filter before concatenating videos. A handful of other attributes have to match as well, like the stream aspect ratio. Refer to the documentation of the filter for more info.
You should convert your sources to the same framerate first.
