Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

🤗Huggingface Model Downloader

Considering the lack of multi-threaded download support in the official huggingface-cli, and the inadequate error handling in hf_transfer, this command-line tool smartly utilizes wget or aria2 for LFS files and git clone for the rest.

Features

⏯️ Resume from breakpoint: You can re-run it or Ctrl+C anytime.
🚀 Multi-threaded Download: Utilize multiple threads to speed up the download process.
🚫 File Exclusion: Use --exclude or --include to skip or specify files, save time for models with duplicate formats (e.g., *.bin or *.safetensors).
🔐 Auth Support: For gated models that require Huggingface login, use --hf_username and --hf_token to authenticate.
🪞 Mirror Site Support: Set up with HF_ENDPOINT environment variable.

Remove MySQL completely

Open the Terminal
Use mysqldump to backup your databases
Check for MySQL processes with: ps -ax | grep mysql
Stop and kill any MySQL processes
Analyze MySQL on HomeBrew:
```
brew remove mysql

Enable TCP port 2375 for external connection to Docker

See this issue.
Docker best practise to Control and configure Docker with systemd.

Create daemon.json file in /etc/docker:

 {"hosts": ["tcp://0.0.0.0:2375", "unix:///var/run/docker.sock"]}

	#!/usr/bin/env bash

	# To fix the " gpg: WARNING: unsafe permissions on homedir '/home/path/to/user/.gnupg' " error
	# Make sure that the .gnupg directory and its contents is accessibile by your user.
	chown -R $(whoami) ~/.gnupg/

	# Also correct the permissions and access rights on the directory
	chmod 600 ~/.gnupg/*
	chmod 700 ~/.gnupg

	@import url("/usr/share/gnome-shell/theme/gnome-shell.css");
	/* customizing GNOME Shell for desktop interface
	with fonts size 9pt (instead default 11pt size) */


	/* Text Styles */
	/* default text style */
	stage {
	font-size: 9pt; /* 11pt */
	}

	我们在一些重大的安全事件发生后，经常会在相关新闻或文档中看到一些相关的安全术语，比如：VUL、CVE、Exp、PoC 等。今天我们就来对这些常用术语的具体含义和用途做一个基本的了解，以便于以后不会在傻傻分不清这些术语的含义。

	什么是 VUL
	VUL，Vulnerability 的缩写，泛指漏洞。

	什么是 0day 漏洞和 0day 攻击
	0day 漏洞，又称零日漏洞「zero-day」。是已经被发现 (有可能未被公开)，而官方还没有相关补丁的漏洞。通俗地讲就是除了漏洞发现者，没有其他的人知道这个漏洞的存在，并且可以有效地加以利用，发起的攻击往往具有很大的突发性与破坏性。

	零日攻击或零时差攻击「zero-dayattack」则是指利用这种漏洞进行的攻击，提供该漏洞细节或者利用程序的人通常是该漏洞的发现者。零日漏洞的利用程序对网络安全具有巨大威胁，因此零日漏洞不但是黑客的最爱，掌握多少零日漏洞也成为评价黑客技术水平的一个重要参数。
