juggling | Various computer vision and machine learning Python scripts | Machine Learning library

I am trying to do a fetch in JavaScript. I have no issues and can get the value I need. I need to pass this value to C# code behind. I have put the value in a hidden field, a div to get the innerHTML and a textbox.value. I don't know what is happening but I cannot seem to access this data from C#. I have an asp:button that executes client side script and then the code behind. Whenever the client side script returns true, the page refreshes. I have tried returning false and the correct values remain on the page but they are not available in the code behind, which is executing (which I find strange since I returned false from the client side). I am including my various attempts so you can see all.

In our application, I would like it to be optional to have to define method arguments, if those are known from a parent:

I have a very slow performance problem when I execute an inference batch loop on a single GPU.

This slow behavior appears after the first batch has been processed - that is when the GPU is already almost full and its memory needs to be recycled to accept the next batch.

At a pristine GPU state - the performance is super fast (as expected).

I hope both the following code snippet and the output illustrate the problem in a nutshell.

(I've removed the print and time measurements from the snippet for brevity)

I have a column with dates and needed to convert them to Unix timestamp. I've managed by converting dates to strings and doing a bit of juggling but was hoping to get insight into a more "elegant" use of GAS date handling and formating. Below is the function I used to get the job done:

Edit 2: I'm replacing the original text of my question and references to my original code with a simpler example instead, per Peter Duniho's suggestion.

I'm developing a WinUI 3 app. The main window has a TreeView, with a hierarchy as follows: the top-level items are of type CarMake, and each CarMake can have 0 or more CarModel children. The window has an ObservableCollection property called Cars which is the source for the top level CarMakes, and each CarMake has an ObservableCollection property CarModels which is the source for its children in the TreeView.

Here's the XAML definitions for the CarMakeView and CarModelView types, respectively:

A bit about my specific use case: I have a plugin that's designed to be integrated with Unreal Engine projects, and in order to demonstrate how to do this to users of the plugin, I've integrated it with one of Unreal's freely available sample games as an example. The integration is very specific to the game, as it does things like modifying the menu to allow the user to interact with my plugin easily.

However, in an ideal world I'd like to be able to:

1. Provide integrations with the sample game across multiple different Unreal Engine versions. At a minimum this would include 3 currently existing versions of Unreal (4.24, 4.25 and 4.26), but would extend to potentially N different future versions. This essentially makes the integration code "boilerplate", as it's required for functionality in each sample game version, but doesn't vary at all across versions.
2. Be able to maintain the bulk of this integration code from one place. I don't want to have to make identical modifications in each of the sample game integrations every time I change something, as juggling multiple parallel codebases like this is a lot of work and increases the probability of bugs.

This is almost a problem that could be solved with code patches: the integration code fits into the same functions/classes in the same files regardless of which version of the sample game I'm using. However, the contents of the sample game files themselves aren't exactly the same across engine versions, so a patch that says "insert this hunk into this file at this line" won't always get it right. There is also the theoretical possibility that a more substantial change is introduced into the sample game in future which could require me to change my integration in that case (though this hasn't happened yet - changes appear to be minimal across minor engine versions).

What is the best way to attack this problem? One particularly horrible way I can think of (but one which demonstrates the concept) would be to separate each chunk of the integration into a separate file, and then #include "Chunk1.inc", #include "Chunk2.inc", ... directly into the relevant classes and functions in each version of the sample game.

I'm using Python (3.8) for sharing files over my network. This is done by a server/listener sending off chunks of the data (when asked for), and a client/recv:er that downloads the data.

All works well with the exception for one thing, the download speed always gradually but quickly becomes slower and slower, making a big impact on a 30MB file and an enormous impact on a 250MB file.

Here is an example of downloading a 25MB file:

Understanding Type Juggling in PHP 8.0 is confusing. The documentation above states no changes to PHP 8.0 with type juggling operators. Take this example:

I'm trying to set the values of an arma::mat element-wise and the value of each element depends on the multi-index (row, column) of each element. Is there a way to retrieve the current location of an element during iteration?

Basically, I'd like to be able to do something like in the sparse matrix iterator, where it.col() and it.row() allow to retrieve the current element's location. For illustration, the example given in the arma::sp_mat iterator documentation) is:
