steve | SteVe - OCPP server implementation in Java

In the wonderful FBlazorShop repo, Onur Gumus is riffing off of Steve Sanderson’s Pizza Workshop with F# flavor. On line 128 of blob/master/FBlazorShop.Web.BlazorClient/Home/Home.fs [GitHub], Onur is passing an Elmish Message for the parent, HomeView, inheriting ElmishComponent , to a child, PizzaConfigView, inheriting ElmishComponent. By convention, we can see Message being converted (?) to PizzaConfigMsg with this:

I want the user to input a String, lets say his or her name. The name can be Jessica or Steve. I want the program to recognize the string but only output the first three letters. It can really be any number of letters I decide I want to output (in this case 3), and yes, I have tried

charAt();

However, I do not want to hard code a string in the program, I want a user input. So it throws me an error. The code below is what I have.

I have two objects, from same class type. They both have a property (and its private field). Conditionally, I would like to assign this property/field as a reference to the same property/field of another instance of the same class.

It's important to note that my requirement is to read the referenced field. Write to it would be a bonus, not a problem, and not necessary.

I would like to know if it would be possible to use a ref field, and do some logic inside the property getter.

Also, I know there has been some questions about this here on StackOverflow (here, here, here, here), but they are all pretty old (so the idea of duplicate does not seem to apply here).
Now we are on C# 10.0, and a lot of different ref capabilities had been implemented, like ref locals. I tried to use some of them, but I failed. Hope someone with more knowledge could help me to see a way to do it.

So, is it possible, without using a wrapper to link one instance's property to another?? (which is my current approach, detailed below)

More details:

That's my class (actually it's a huge simplification of it):

Microsoft extensions to C and C++:

To perform the same cast and also maintain ANSI compatibility, you can cast the function pointer to a uintptr_t before you cast it to a data pointer:

I have an object which looks like this :

I am a Pandas newbie and I am trying to automate the processing of ticket data we get from our IT ticketing system. After experimenting I was able to get 80 percent of the way to the result I am looking for.

Currently I pull in the ticket data from a CSV into a "df" dataframe. I then want to summarize the data for the higher ups to review and get high level info like totals and average "age" of tickets (number of days between ticket creation date and current date).

Here's an example of the ticket data for "df" dataframe:

I then create "df2" dataframe to summarize df using:

I have a table with x num of rows, I have a second table with the same number of rows but different columns and metadata, they have different table models. but each row represents the same object (a song).

I want to synchronize row sorting between the two tables so for example if I sort on column 2 of table 1 then rows of the table will be sorted in the same order. But currently, I just have sorted by matching sort keys so sort on the same column (but because different data get different results)

I'm attempting to plot a 2D dataset having unstructured coordinates in matplotlib using tricontourf. I'm able to generate a plot of the 'mesh' with triplot, however when I use the same Triangulation object for tricontourf, I get an error (see below). What am I missing? Example:

I get an error (after update RestSharp - v107) on the following line:

var contacts = new JsonDeserializer().Deserialize>(response);

Error CS0246 The type or namespace name 'JsonDeserializer' could not be found (are you missing a using directive or an assembly reference?)
