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

Stable Diffusion model conversion script

Convert from the 'original implementation' to Huggingface diffusers. Both .safetensors and .ckpt checkpoints are supported.

The script is adapted from the diffusers conversion script: https://github.com/huggingface/diffusers/blob/main/scripts/convert_original_stable_diffusion_to_diffusers.py

Usage:

python enhanced_convert_original_stable_diffusion_to_diffusers.py --checkpoint_path "<input_model_filepath>" --dump_path "<output_directory_path>" --extract_ema

For inference use, extracting with --extract_ema is usually recommended. This will be ignored if the source model does not contain both EMA and non-EMA weights.
