cml | A header-only C matrix library | Math library

I'm trying to use and convert following code in a Pine screener

I am writing a set of tools to crack Vigenere cipher for a school project. There is a problem that I know I can solve if I could pass pointers like in C but I started this in Python and I don't want to rewrite everything. Code is on https://github.com/DarkFireGuy/cracking-vigenere if you want to see

freq_analysis.py has a function _plot() that is used to plot and save the image. After pyplot has created the graph I check to see if the file has an extension. If it doesn't then I call simple_popup() from tools.py (small collection of nifty little functions). This call sends three pieces of information to a function that makes it easier for me to simplify tkinter use:

1. A message to tell the user that the file name is bad and doesn't have an extension,
2. Button labels to tell the user which one does what.
3. Functions to tell each button what they're supposed to do.

If the user presses the button to enter a new name I would call simple_popup_input() (not written yet) to take the new input. But I cannot do that until I figure out how I would get the input into the fext (file extension). For now I am using exec to take user input and putting it into fext (txt on cml no fancy pants tkinter yet) but this fext is not the same fext from before. To fix all of this I need to be to write to the address at which fext is located. Google told me it wasn't possible in python so I have come to the council of smart people to see what I should do.

1. Rewrite the whole thing in C

2. Figure out how to get the memory address of fext

3. (just came to me while writing this) write the new file extension to a temporary file and then read it after the simple_popup_input() call --- Don't want to do this because there has be a more elegant solution

4. Don't know how it would work but to include two tuples which will contain arguments that get passed into func1 and func2. simple_popup header would become:

I have a custom matrix library based on CRTP, tested, for dynamic matrices:

So I have a CRTP class for matrices (still fresh in this topic), with a Matrix_Base and a derived Dynamic_Matrix class (and also a Static_Matrix derived class). Minimal example included:

Matrix_Base is defined in cml.h:

I'm working on a web-fragment to isolate a specialized process needed in only one part of our overall production process. I'm trying to define a JNDI resource specific to the web-fragment, but I keep running into a brick wall.

The application is running in Tomcat 9. I am using Web-Fragment specification 4.0.

The working model, right now, is I have the database connection defined as a global resource in the server.xml as such:

I have a JPQL query with a JOIN ... ON ... clause, which is valid since JPA 2.1:

My training job on the AI platform on the Google Cloud Platform seems to be running but is not consuming any CPU. The program does not terminate, but it does give a few errors when the job first started running. They look like below

We are building an app which requires an API request. On front end we are using Ionic with Angular. When we tried to send a request to backend we get this error.

It works when we are trying on desktop in browser.

I'm trying to use Python API to run some playbooks because I want to integrate it with Flash to enable the web-base control. Here is my playbook(crondis.yaml):
