staking | A dAPP for minting , burning , and earning on the Synthetix | Cryptocurrency library

I have been trying to figure this out for hours. I've seen this SO question and I still cannot figure this out.

I have some Jason data that I know begins like this:

I'm trying to use dplyr::summarize() and dplyr::across() to obtain a tibble with several summary statistics in the rows and the variables in the columns. I was only able to achieve this result by using dplyr::bind_rows(), but I'm wondering if there's a more elegant way to get the same output.

1. In the internal_restake function, why do we have to access the on_stake_action function as if it's an external cross contract call when its a function thats a part of the calling contract? Couldn't we just do .then(self.on_stake_action()) instead? I'm assuming it has something to do with the face that it's a callback from stake() promise call.

2. In what situation would you make an interface for the contract itself like ext_self?

3. What does the #[ext_contract()] macro do in a nutshell?

I have a large table with a comments column (contains large strings of text) and a date column on which the comment was posted. I created a separate vector of keywords (we'll call this key) and I want to count how many matches there are for each day. This gets me close, however it counts matches across the entire dataset, where I need it broken down by each day. The code:

I am new to python/coding and I'm seeking some basic help to pull some elements from what I think is a dictionary. So I am executing the below.

I need a button group like the one shown in the code below and want to apply a border-shadow when the user hover's on top of a button.

The elements seem to be staking on top of each other from left to right, covering the right side's border-shadow.

How can I prevent this?

I tried z-index and doesn't work on my code but I can see it working on other people's code snippets...

I have 2 lines of code which both work well separately helping me to calculate staking, but I need to have both lines work in a single cell, but depending on additional criteria. For the life of me I haven't been able to get it to work Code 1

Is it possible to query:

1. the set of delegators for a given validator at a specific height?
2. the amount each delegator has delegated to a given validator at a specific height?

Something like the output of the /staking/delegators/{delegatorAddr}/delegations RPC endpoint, but at a specific height.

I think it might be possible via /abci_query, but not sure on the path and data arguments.

I'm using TailwindCSS and AlpineJS in my project and, when loading the login page, for a brief moment there is a flash of the header dropdowns opening. For this, I try to use x-cloak, but it is not working properly and I cannot understand why, since I used it on other pages and it worked perfectly.

This is my code snippet:
