This is my school program that crashes on me, probably something from (Segmentation fault / Bus error / Memory limit exceeded / Stack limit exceeded). I can't figure out where the mistake is. I tried to comment on the code and reduce it a bit.

I have package called sandwich, it then has:

A file flavours.jl which defines a struct HamCheeseSandwich.

The file factory.jl is a module which first first runs include("flavours.jl") and has a method make_sandwich which creates a HamCheeseSandwich, except rather than producing a HamCheeseSandwich it returns sandwich.factory.HamCheeseSandwich

The last file is printer.jl , here the sandwich made in factory.jl fails with MethodError: no method matching print_sandwich(::sandwich.factory.HamCheeseSandwich)

So I am practising using newtonsoft.Json by creating a very simple Register.

In this code a user enters a first name and last name and this is put into my very simple Person object, which is then put into a List

The user can add multiple people and they are put into the List

My code isn't working and I need help because I am learning.

It isn't working because the serialization and deserialization process is coded wrong I think.

At the beginning of the code a List is declared with the People from the json file

I am trying to use kernel density smoothing to map the intensity of possible pest escape from vehicle traffic. Each route has been broken down into straight lines with each line having an integer attribute for the number of times the segment was travelled upon. However, when I use this attribute as the weight in kernel density smoothing, the weights don't seem to be used.

I've created a simplified reprex below with two abutting straight lines. Can anyone explain to me how I can make density.psp() account for the fact that one segment has an attribute 2x the magnitude of the other?

Many thanks for your help,

Josh

I'm trying to update a piece of old code (a menu builder class). I've updated everything else but I'm stuck at a line that uses the each() function. I did read some of the previous threads but this particular instance is too complex for me to figure out how to change. Here it is:
