Objective-See: An Open Source Project Org for Apple Privacy and Security

Objective-See: An Open Source Project Org for Apple Privacy and Security While searching for small tools today, I found they have built a bunch of open-source software for macOS, mostly related to privacy and security. KnockKnock: See what background processes, daemons, launch items, kernel extensions, login items, browser plugins, and more are on your Mac. Much more detailed than “Login Items” (some software auto-starts in other ways). LuLu: An open-source macOS network firewall that lets you control each application’s network connections in detail (similar to Hands Off!).

Convert Cloudflare WARP to an HTTP Proxy

Convert Cloudflare WARP to an HTTP Proxy warp-cli proxy port 60606 warp-cli mode proxy However, Go programs do not support SOCKS proxies, and I don’t want to manually add a transport. The good news is that Go respects the http_proxy environment variable by default. So we need to convert the SOCKS proxy to an HTTP proxy. pproxy -v -l http://127.0.0.1:8118 -r socks5://127.0.0.1:60606 https_proxy=http://127.0.0.1:8118 http_proxy=http://127.0.0.1:8118 curl ipv4.win curl: (52) Empty reply from server # pproxy logs Serving on ipv? 127.0.0.1:8118 by http http 127.0.0.1:45012 -> socks5 127.0.0.1:60606 -> ipv4.win:80 Unknown remote protocol from 127.0.0.1 Maybe it’s a pproxy issue, so try gost.

Advanced Shell Scripting Techniques: Automating Complex Tasks with Bash

Advanced Shell Scripting Techniques: Automating Complex Tasks with Bash Use Built-in Commands Built-in commands execute faster because they don’t require loading an external process. Minimize Subshells Subshells can be expensive in terms of performance. # Inefficient output=$(cat file.txt) # Efficient output=$(<file.txt) Use Arrays for Bulk Data When handling a large amount of data, arrays can be more efficient and easier to manage than multiple variables. # Inefficient item1="apple" item2="banana" item3="cherry" # Efficient items=("apple" "banana" "cherry") for item in "${items[@]}"; do echo "$item" done Enable Noclobber To prevent accidental overwriting of files. set -o noclobber Use Functions Functions allow you to encapsulate and reuse code, making scripts cleaner and reducing redundancy. Efficient File Operations When performing file operations, use efficient techniques to minimize resource usage. # Inefficient while read -r line; do echo "$line" done < file.txt # Efficient while IFS= read -r line; do echo "$line" done < file.txt Parallel Processing Tools like xargs and GNU parallel can be incredibly useful. Error Handling Robust error handling is critical for creating reliable and maintainable scripts. # Exit on Error: Using set -e ensures that your script exits immediately if any command fails, preventing cascading errors. set -e # Custom Error Messages: Implement custom error messages to provide more context when something goes wrong. command1 || { echo "command1 failed"; exit 1; } # Trap Signals: Use the `trap` command to catch and handle signals and errors gracefully. trap 'echo "Error occurred"; cleanup; exit 1' ERR function cleanup() { # Cleanup code } # Validate Inputs: Always validate user inputs and script arguments to prevent unexpected behavior. if [[ -z "$1" ]]; then echo "Usage: $0 <argument>" exit 1 fi # Logging: Implement logging to keep track of script execution and diagnose issues. logfile="script.log" exec > >(tee -i $logfile) exec 2>&1 echo "Script started" Automating Complex System Administration Tasks: Automated Backups System Monitoring User Management Automated Updates Network Configuration
