I am trying to produce a contour plot of the following function in R,

Where the values of Y_{t-1} and Y_{t-2} are between -1 and 1 and e_t just follows a normal distribution with mean 0 and standard deviation .2, i.e. e_t~N(0,.2).

I've gone ahead and set up the code to handle the function as well as calculating the value of y_t however I'm having two of the following issues.

1. When defining the contour() function in R I'm having issues setup up the z value and I get an improper output.

2. When I try to fill in the plot with colors using filled.contour() I get the "Error in seq.default(0, 1, length.out = ncol(z)) : argument 'length.out' must be of length 1" error and I am unsure of how to solve it.

At the end, I want to obtain a contour plot that looks like the following or similar to,

Below I've provided some sample code I've been goofing around with which only produces a simple contour plot with the function y_t not properly defined.

I have a SwiftUI app that I have distributed to my testers. I have deployed my development schema to production cleanly and I have also tested with com.apple.developer.icloud-container-environment in entitlements set to "Production". However what I am finding is that when I compile and run the app via Xcode, all is well. My test devices and simulators are sharing the data as I'd expect, in both the development and production private and public databases.

However, when I package it up, I've tried manual and automatic signing, and release it through TestFlight and load it into the same physical devices that previously worked via Xcode, no syncing occurs, it just seems to write to local store.

Then when I connect to Xcode and rerun the app, overwriting the TestFlight version (i.e. I'm not deleting the local store, just the app) the records I created with the TestFlight version will now make their way to the Production database.

I am guessing that I have goofed somewhere along the line with certificates, but I have recreated new provisioning profiles and new certificates - I admit I find this part confusing, I'm quite new to this - but to no avail. I've read through the documentation and searched the web, but I'm not getting any leads. Any suggestions on what I am doing wrong would be gratefully received.

Thanks

Asked a question earlier today, but managed to figure out my answer from earlier after some goofing around. I have a new question though. I'm still really new to python, and I'm working on my first mid-term project. My code currently runs exactly to the specifications the instructor has asked for, however I would like to add a little extra by making sure that the only input the code will accept from the user is an integer. I've looked at a posts and seen how it can be done, but I don't quite understand yet. Can someone show me how I would be able to write an exception handler into my code that continues to loop properly?

out of curiosity I started goofing around with selenium and BeautifulSoup. The Code below is working quit fine for me. I only want to know if there is a better//shorter way to save the data to the dict instead of using the two seperated lists and for loops.

The code is scraping amazon for a book via the ISBN-13 number and than get some information about the book.

I am trying to separate an encryption function from our legacy code to a dll which I can call from C#, but I am having issues getting it to work and I keep getting access violations when calling the dll.

I am not sure where the AV happens because delphi has a hard time hitting my breakpoints when the dll is attached to another process.

I got it to work yesterday using David Heffernan's answer here: Returning a string from delphi dll to C# caller in 64 bit But my success was short-lived as I changed the string parameters to regular string's (delphi) saw it didn't work and changed them back to to AnsiString (our encryption routine expects Ansi). Since I changed these param types. I have not been able to get it to work again.

Here is my Delphi Code:

I am using this Dockerfile to create an image and start a container:

I have two dataframe like the following but with more rows:

I just put in a Dockerfile for some Python code I need to get into GKE.

I would like to do basic word counts of html files, excluding some elements that shouldn't be included. A sample file might look like the following:
