QUESTION
I have a struct with a method called call which has a const overload. The one and only argument is a std::function which either takes a int reference or a const int reference, depending on the overload.
The genericCall method does exactly the same thing but uses a template parameter instead of a std::function as type.
ANSWER
Answered 2022-Apr-08 at 13:25The problem is that generic lambdas (auto param) are equivalent to a callable object whose operator() is templated. This means that the actual type of the lambda argument is not contained in the lambda, and only deduced when the lambda is invoked.
However in your case, by having specific std::function arguments, you force a conversion to a concrete type before the lambda is invoked, so there is no way to deduce the auto type from anything. There is no SFINAE in a non-template context.
With no specific argument type, both your call are valid overloads. Actually any std::function that can match an [](auto&) is valid. Now the only rule is probably that the most cv-qualified overload wins. You can try with a volatile float& and you will see it will still choose that. Once it choose this overload, the compilation will fail when trying to invoke.
QUESTION
Environment: Windows Server 2022 21H2, Powershell 7.2 (running as administrator)
I have a script that implements ShouldProcess, which works fine in Windows PowerShell 5. However, in PowerShell 7, the script invariably throws the error Cannot find an overload for "ShouldProcess" and the argument count: "1". ShouldProcess at MSDoc says that the one-argument overload for $PSCmdlet.ShouldProcess() exists and should work.
It's failing, as above. Why?
The script in question is pasted below; it's in a script module:
...ANSWER
Answered 2022-Mar-11 at 14:21For reference, this error can be reproduced on both PowerShell versions 5.1 and Core. The steps to reproduce is passing a System.Management.Automation.PSObject as argument to the .ShouldProcess(String) overload. It makes sense, by looking at your comment mentioning a serialized object. In below example, if the System.Diagnostics.Process object is not serialized it works properly on both versions.
QUESTION
I'd like to skip validation for empty arrays in a json file for a specific field. Below you can see Book structs definition, which could be validated if no authors are declared in json file. On the other hand it fails if an empty array is defined for authors. Is it possible to achieve this behavior with existing tags, or do I have to define custom validator?
...ANSWER
Answered 2022-Feb-26 at 20:02It's because your Authors validation string is "omitempty,min=1,dive,min=3". The length of an empty slice is 0, which is <1.
If you replace the validation string with "omitempty,min=0,dive,min=3" instead, it'll pass.

Am starting off in blockchain development using the book Mastering Blockchain - A deep dive into distributed ledgers, consensus protocols, smart contracts, DApps, cryptocurrencies, Ethereum,
Am using WSL with geth version 1.10.9.
...ANSWER
Answered 2021-Oct-11 at 23:20It appears 1.10.9-stable version has a problem and is returning a -rpc error. GETH 1.10.8-stable version works fine when running the geth command with --rpc
QUESTION
Is there a better way to do this task?
For the pre-processing of an NLP task, I was trying to split large pieces of text into a list of strings of even length.
By splitting the text at every "." I would have very uneven sentences in length. By using an index/number I would cut off sentences in the middle.
The goal was to have sentences in a list of even length without truncating a sentence before it ends.
This is the solution I came up with but I feel like something simpler should exist.

I am watching Paul O Shannessy - Building React From Scratch
And I understand the mounting process very well but I have hard day trying to understand how React update a component and its children
The reconciler controls the update process by this method:
...ANSWER
Answered 2022-Jan-12 at 09:47I think React not re-render parent component first instead of that, React re-render child component first.
Example: A (parent) -> B (child) -> C (child of B) When A update state C (re-render) -> B -> A
QUESTION
I have a Piece of code that's supposed to change the text displayed according to the current day of the week and the time of day.
For some reason the if/else statements I'm using to check variables are altering the day variable. The end value changes from day do day and removing sections of if else statements also change the result.
I plan on embedding this on a WordPress site using the HTML block
...ANSWER
Answered 2022-Jan-19 at 09:33This is happening because you are assigning the value in the if check. instead of assigning it using =, use == or === to check for equality
QUESTION
I made a simple sqrt struct using TMP. It goes like :
ANSWER
Answered 2022-Jan-17 at 07:12The thing is that in TMP you can't go very deep by default. The depth is limited but the limit can be changed (see this). The other thing is that you write your TMP code with recursion but it can be compiled into a non-recursive code so it doesn't have the extra cost of saving the state and doing a function call as it goes deeper. So it is a tradeoff between compile time, executable size and runtime performance. If your N is not known at compile time, then you can't use TMP.
QUESTION
I am currently working on a measurement system that uses quantitative image analysis to find the diameter of plastic filament. Below are the original image and the processed binary image, using DipLib (PyDIP variant) to do so.
The ProblemOkay so that looks great, in my personal opinion. the next issue is I am trying to calculate the distance between the top edge and the bottom edge of the filament in the binary image. This was pretty simple to do using OpenCV, but with the limited functionality in the PyDIP variant of DipLib, I'm having a lot of trouble.
Potential SolutionLogically I think I can just scan down the columns of pixels and look for the first row the pixel changes from 0 to 255, and vice-versa for the bottom edge. Then I could take those values, somehow create a best-fit line, and then calculate the distance between them. Unfortunately I'm struggling with the first part of this. I was hoping someone with some experience might be able to help me out.
BackstoryI am using DipLib because OpenCV is great for detection, but not quantification. I have seen other examples such as this one here that uses the measure functions to get diameter from a similar setup.
My code: ...ANSWER
Answered 2022-Jan-02 at 22:56Here is how you can use the np.diff() method to find the index of first row from where the pixel changes from 0 to 255, and vice-versa for the bottom edge (the cv2 is only there to read in the image and threshold it, which you have already accomplished using diplib):
