I'm writing a book using the bookdown package. I have a table that contains the less equal symbol with the $\leq$. When I render the book in HTML the symbol is visualized but I have to add one slash more $\\leq$. When i render the book in pdf the symbol is not rendered. How can I solve this?

Celery disconnects from RabbitMQ each time a task is passed to rabbitMQ, however the task does eventually succeed:

My questions are:

1. How can I solve this issue?
2. What improvements can you suggest for my celery/rabbitmq configuration?

I am using a row, inside it, each text is a column and I want that whenever my text overflows, it should automatically go to next line, I tried everything, but it won't work. When I tried to use expanded or flexible, it gave error.

I'm still learning the fundamentals of Javascript, but I know there's a way to simplify this one, I just can't figure it out. I've modified a script I found here: Protect spreadsheet then unprotect specific cells and ranges with script

I'm sharing a sheet with multiple users and want most of each sheet protected. The above linked script helped me ensure that the ranges my users need access to can be edited by all even as the sheets expand. However, the editable ranges are different on each sheet, so I've ended up recycling the unlockCertainRanges() portion to apply it to each sheet individually. This has made the script take up to 70 seconds to run. I'm pretty sure I can use an array and a for loop to run through each sheet, but I'm having trouble figuring it out.

This is what I have so far:

I have recently become familiar with the rstatix package. Below is an example code using functions from this package.

I am trying to create a simple frontend using Typescript and a backend server with Flask and send requests via axios, as I have been using. Somehow I am getting this strange error in the browser console:

Access to XMLHttpRequest at 'http://localhost:5000/api/test' from origin 'http://localhost:3000' has been blocked by CORS policy: Request header field content-type is not allowed by Access-Control-Allow-Headers in preflight response. POST http://localhost:5000/api/test net::ERR_FAILED

It says my header has some field that is illegal due to CORS setup. But the thing is:

1. I have a CORS set up in the backend flask server:
