For REST APIs it usually happens to encode client-id and client-secret to send to an endpoint to get access token.
It has been said in API documentation that send data like below:

Basic BASE64_ENCODEDED_VALUE_OF(CLIENT_ID:CLIENT_SECRET)

There is an online tool for exactly that specific purpose (encode, decode base64).

Go to link below:
- https://www.base64encode.org/

#base64 #base64encode #client_id #client_secret #api #rest #webservice

To get on going processes in mysql client and see which queries are taking longer use:

SHOW PROCESSLIST;

It will show you a table with list of all connection from different hosts (if applicable) and their PID number. You can use this number to kill a process that consumes your server CPU, Memory, etc.:

KILL <pid>;

#mysql #client #kill #processlist #sysadmin #dba #linux
