-- First method
SELECT * FROM t1
LEFT JOIN t2 ON t1.id = t2.id
UNION
SELECT * FROM t1
RIGHT JOIN t2 ON t1.id = t2.id

-- Second Method
-- The query above works for special cases where a FULL OUTER JOIN operation would not produce any duplicate rows. 
-- The query above depends on the UNION set operator to remove duplicate rows introduced by the query pattern.

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

1. Generate ssh key pairs for accounts and add them to GitHub accounts.

A micro event loop library implementation from scratch.

This library provides a minimal but feature-complete asynchronous event loop
implementation for educational purposes. It demonstrates the core concepts of
asynchronous programming including:

- Task scheduling and management
- I/O multiplexing with non-blocking sockets
- Timeouts and sleep functionality
