I have encountered what i consider to be a strange situation with std::visit and overloaded which is giving me a compiler error. To illustrate what i am trying to do I have an example using std::visit 3 different ways.

• Approach 1, calling std::visit directly on a variant which returns a T const&,
• Approach 2, wrapping the std::visit code in a free function: T const& fn(variantT const&)
• Approach 3, wrapping the variant in a structure with an accessor T const& get_XXX() const

My goal is to be able to wrap the std::visit part in a function because in my use case it's not a small piece of code. I have multiple lambda overloads. I don't want to have to duplicate this code in each function that uses the variant and wants to get a property, i want to write it once in some kind of wrapper which i can re-use across multiple translation units (Approach 3 is most preferable to me, then Apporach 2, and all else fails, I will investigate something less pleasing like a macro or something.)

Can someone explain to me:

• Why / where std::visit is creating a temporary object?
• Is there something I can do differently to prevent this temporary from being created?
• Accepting that a temporary exists for some reason or other, why does the temporary object lifetime extension rule not apply here?

Please consider this minimal example which reproduces the problem I am seeing.

Consider the following scenario. I have a list of strings.

var list = new List { "Ringo", "John", "Paul", "George" };

I need to sort the list and return ALL values after a specific value. For instance, if the value I need to filter off of the name "George", I want to return:

{ "John", "Paul", "Ringo" }

Sorting using standard List methods or linq is simple enough, but since these are text strings, I'm drawing a blank on figuring out how to take all values after a specific filter since you can't us a greater-than sign in your where clause.

How can I do this. Linq is preferable but not required.

I have two collections, one is a list of image names, the second is a subset of that list. When a task has been completed its name is inserted into the second collection.

I need to retrieve a set of not yet completed image names from the first collection. I have achieved this successfully with:

I am trying to plot the quantile regression lines for a set of data. I would like to extend the quantile regression lines from geom_quantile() in order to show how they forecast similar to using stat_smooth() with the fullrange argument set to TRUE. However, there is no fullrange argument for geom_quantile(). As an example, see below:

I have a large number of JSON requests for a model split across multiple files in an S3 bucket. I would like to use Sagemaker's Batch Transform feature to process all of these requests (I have done a couple of test runs using small amounts of data and the transform job succeeds). My main issue is here (https://docs.aws.amazon.com/sagemaker/latest/dg/batch-transform.html#batch-transform-errors), specifically:

If a batch transform job fails to process an input file because of a problem with the dataset, SageMaker marks the job as failed. If an input file contains a bad record, the transform job doesn't create an output file for that input file because doing so prevents it from maintaining the same order in the transformed data as in the input file. When your dataset has multiple input files, a transform job continues to process input files even if it fails to process one. The processed files still generate useable results.

This is not preferable mainly because if 1 request fails (whether its a transient error, a malformmated request, or something wrong with the model container) in a file with a large number of requests, all of those requests will get discarded (even if all of them succeeded and the last one failed). I would ideally prefer Sagemaker to just write the output of the failed response to the file and keep going, rather than discarding the entire file.

My question is, are there any suggestions to mitigating this issue? I was thinking about storing 1 request per file in S3, but this seems somewhat ridiculous? Even if I did this, is there a good way of seeing which requests specifically failed after the transform job finishes?

Say I have two 2d arrays:

What is the difference between the following two ways to define a prototype, and is one more correct than the other?

I am trying to build a template of a Multiplatform library module in Android studio that can interoperate seamlessly with other normal Android library and application modules. I've found it's easy enough to make a Multiplatform Android project technically work in terms of compiling, running and publishing artefacts, but one problem I can't seem to solve is getting the source sets to show correctly in the Android project files pane view.

So you can see in the Project view here, the sources are divided into android, native and common directories and their respective test directories, for a total of six source directories:

In the Android Project view this is rendered by build targets instead of source file directories, so that this 'typing-sdk' module example has total of 10 different sub-modules. And you'll notice androidMain and androidTest are not among them: instead of being rendered as submodules, their sources fall under an inline kotlin directory instead; you can see the main and test com.demo.typing packages respectively.

It is a little annoying that every single build target gets its own submodule, when in practice, one will virtually never actually need to use some of these, like 'iosArm64Test' for example. Nevertheless, I can live with redundant submodules. The central problem here is that each of these submodules are populated with the wrong source files.

So whereas in the file structure, both the common and native sets have their own source files, as you can seen here:

In the Android Project View, every single submodule contains the Android sources!?

Either this is a bug in how Android Studio interoperates with the Kotlin Multiplatform Gradle Plugin, or there's something wrong with the Gradle build file I have written, which is this (using Gradle 7.1):

I have a project that uses a lot of reflection, also on "new" Java features such as records and sealed classes. I'm writing a class like this:
