BlockHead | sticky elements | Frontend Framework library

As a project I was implementing MinMax Tic Tac Toe AI in Python. I further implemented Alpha - Beta Pruning and came up with this huge code.

Code:-

im new to Entity framework and i dont understand why it is giving me an error in sql syntax , i thought the whole purpose of using EFCore is to handle the sql syntax and abstract all the sql queries away

here is my model :

I am trying to adapt my simple blockchain implementation to save the blockchain to the hard drive periodically and so i looked info different db solutions. i decided to use RocksDb due to its ease of use and good documentation & examples. i read through the documentation and could not figure out how to adapt it to my use case. i have a class Block `

I have created an Interior variable in vba to store the style of a certain cell. Excel lets me do it but when I try to apply that style to any other cell it does not work.

I have a system that has lots of Blocks of data stored in a vector of structs The struct looks like this:

Built API with NodeJS, Express & MongoDB, used JWT and Cookies for user authentication. Fetched user data from API with axios service using store (vuex). Created auth.js in store folder, created fetchData action which GETs the data from backend (axios.get(apiRoute)) and sets the user to state. Wanted to do this using nuxtServerInit, so i craeted index.js file in store folder. Added empty state & actions. Action containts nuxtServerInit which uses dispatch() to call fetchData method in auth.js.

Yet after all of this, it doesn't work at all. For example: User is logged in, but account page is not rendering with user data (name, email, image etc.).

I tried returning a promise from fetchData action in auth.js, and it didn't work. Also i tried setting up fetchData action insite of the index.js file and calling dispatch directly on it.

store/auth.js

A probably simple question - but I´m blockheaded:

Following sabre/vobject usage instruction I will loop the TEL-property to get numbers and their types.

I am writing a makeshift little private 'block chain' for illustrative purposes to be used as a teaching tool. I have all the core functionality ironed out, but I was thinking about some of the more peculiar aspects of block chain and found myself wondering about longs in java. The 'miner' method I have built into the application increments a nonce value of type long with the ++ operator until a condition is met. My question is, if I wanted to avoid (or at least greatly prolong) the chance of exhausting the integer nonce space (2147483647), if I initialized the starting nonce value I pass to the miner method with Nonce = 0L; could I increment it with the ++ operator and make use of the full long literal range?

It's my understanding that Bitcoin uses a special input value into the transaction, and/or some miners will slightly change the time stamp for "ExtraNonce" but since this is just for illustrative purposes I don't want to go as far as including something similar into the app.

I can provide code snippets if anyone wants to see them for any reason, any thoughts would be greatly appreciated!

Code below:

(please don't heckle me on my questionable if/else control logic, this isn't a legitimate production application and I am still a novice in java)

This is the code from the launcher class that calls the miner method:

I am writing a java application that will hash a series of input values repeatedly until a condition is met. I have accomplished this by nesting a series of if/else statements inside a while loop. I want to be able to print the hash rate to the terminal every 3 seconds while the application is actively hashing, and not repeatedly until the condition is met. I have tried using ExecutorService and scheduling a TimerTask but neither worked the way I wanted them to as they both kept on executing after the condition that should have stopped them was met. I know I am missing something but I don't know what ):

I've included a small snippet, feel free to ask for any information you may think is relevant.

Any help would be greatly appreciated!

I tried using a TimerTask like this:
