Learning Rust

The following is a list of resources for learning Rust as well as tips and tricks for learning the language faster.

Warning

Rust is not C or C++ so the way your accustomed to do things in those languages might not work in Rust. The best way to learn Rust is to embrace its best practices and see where that takes you.

The generally recommended path is to start by reading the books, and doing small coding exercises until the rules around borrow checking become intuitive. Once this happens, then you can expand to more real world projects. If you find yourself struggling hard with the borrow checker, seek help. It very well could be that you're trying to solve your problem in a way that goes against how Rust wants you to work.

Introduction

Let’s Encrypt is a free, automated, and open certificate authority (CA), run for the public’s benefit. So far it works well and makes it easy to obtain a free certificate. Now the created certificates will expire withing 90 days. This post will show you how you can auto renew these certificates before they expire.

Requirements

Ubuntu server

Reset MySQL 8.0 root Password in Windows

Stop the MySQL 8.0service from services
Go to path C:\Program Files\MySQL\MySQL Server 8.0\bin and open cmd
Run mysqld --console --skip-grant-tables --shared-memory
Open new cmd in the same path
Run following commands
mysql -u root
select authentication_string,host from mysql.user where user='root';
UPDATE mysql.user SET authentication_string='' WHERE user='root';

Example Queries

1h active keys by location:

sum(max(increase(shadowsocks_data_bytes{access_key!=""} [1h])) by (access_key, location) > bool 0) by (location)

1h usage by location:

sum(increase(shadowsocks_data_bytes{dir=~"c<p|p>t"} [1h])) by (location)

Semantic Commit Messages

See how a minor change to your commit message style can make you a better programmer.

Format: <type>(<scope>): <subject>

<scope> is optional

	#!/usr/bin/env bash

	# Usage:
	# - Install `tesseract` with `brew install tesseract`
	# - In BetterTouchTool, create a trigger of your choice.
	# (I recommend a Keyboard Shortcut with Cmd+Shift 6)
	# - Add an Execute Shell Script / Task action
	# - Paste this script.
	# NOTE: You'll need to authorize BTT to the Screen Recording permission in Security and Privacy at System Preferences
