The Fundamental Skills

These are the basics that every hacker should know before even trying to hack. Once you have a good grasp on everything in this section, you can move into the intermediary level.

1Basic Computer Skills

It probably goes without saying that to become a hacker you need some basic computer skills. These skills go beyond the ability to create a Word document or cruise the Internet. You need to be able to use the command line in Windows, edit the registry, and set up your networking parameters.

Many of these basic skills can be acquired in a basic computer skills course like A+.

How to make a Release Android App debuggable

Let's say you want to access the application shared preferences in /data/data/com.mypackage.
You could try to run adb shell and then run-as com.mypackage ( or adb shell run-as com.mypackge ls /data/data/com.mypackage/shared_prefs), but on a production release app downloaded from an app store you're most likely to see:

run-as: Package 'com.mypackage' is not debuggable

Using GitHub Codespaces is my new default for editing a static Jekyll site

Navigate to a repo where you have your Jekyll static site (maybe your GitHub pages site)
Launch Codespaces (Code button -> Cloud -> New codespace on current branch)
Once it's launched, run the following in the terminal

gem install bundler jekyll
bundle update
bundle exec jekyll serve

	# This is a hack to make Bluetooth headests like the jabra Evolve 65 actually
	# work as a headset with the Linux (Ubuntu/Debian) Zoom client without having
	# to switch manually from A2DP to the HSP/HFP profile.
	#
	# This is done by injecting an environment variable which makes PulseAudio
	# recognize the application as a telephony/voice application as described
	# here:

	# VERY IMPORTANT! After each kernel update or dkms rebuild the modules must be signed again with the script
	# ~/.ssl/sign-all-modules.sh

	# Place all files in ~/.ssl folder
	mkdir ~/.ssl
	cd ~/.ssl

	# Generate custom keys with openssl
	openssl req -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -nodes -subj "/CN=Owner/"

	import java.io.DataOutputStream;
	import java.io.IOException;
	import java.io.OutputStream;
	import java.net.Socket;

	public class Client {
	public static void main(String[] args) throws IOException {
	// need host and port, we want to connect to the ServerSocket at port 7777
	Socket socket = new Socket("localhost", 7777);
	System.out.println("Connected!");
