With LD_PRELOAD, you can override functions in shared libraries before any program even starts. Want to intercept malloc, block file access, or spoof system calls without touching source code? This is how you do it. It’s an advanced but incredibly powerful debugging and hacking tool. One that developers and exploit authors alike keep close. You can use it to mock dependencies during testing, inject logging for hard-to-trace bugs, or even subvert DRM and monitoring software. It’s not just a trick, it’s a backdoor into the behavior of nearly any dynamic binary.

If you spend any amount of time on the command line and often need to read #Markdown .md files, for longer documents, wouldn't it be nice to see them formatted, and use the links?

You absolutely can using two utilities you probably already have on your system: #pandoc and #lynx.

I've added a function to my .bashrc to use it:

md() { pandoc $1 | lynx --stdin }

Usage:
md README.md

Of course, you can name the function anything you wish.

Linux kernel hardening is a crucial aspect of securing your system. By implementing techniques such as kernel-level access controls and removing unnecessary kernel modules, you can greatly reduce the attack surface of your system and increase its resistance to malicious actors. Don't neglect this crucial step in your overall security strategy.

For anyone use vim command everywhere:

if you type vim quit command in to a shell you will definitely got a command not found.

Those alias can help you to solve those issue:

# Quit shell
alias :q='exit'
alias :wq='exit'

alias :q!='kill -9 $$'
