One time setup:
``
git clone https://github.com/cirosantilli/linux-kernel-module-cheat
cd linux-kernel-module-cheat
sudo apt install docker
python3 -m venv .venv
. .venv/bin/activate

./run-docker create
./run-docker sh
``

You are now in Docker.

Build everything from source inside docker:
``
./build --download-dependencies qemu-buildroot
``

Boot Linux and get a userland shell:
``
./run

The following are https://github.com/cirosantilli/linux-kernel-module-cheat/blob/master/submodules[stored in submodules]:
``
submodules/binutils-gdb/
submodules/buildroot/
submodules/gcc/
submodules/glibc/
submodules/linux/
submodules/qemu/
``

So you can modify source, rebuild and that's it, its in the VM.

E.g., let's hack the linux kernel:

``
asmlinkage __visible void __init __no_sanitize_address start_kernel(void)
{
  pr_info("I'VE HACKED THE LINUX KERNEL!!!");
``

Rebuild Linux:

``
./build-linux
``

Rerun:

``
./run
``

And after boot we see:

``
<6>[    0.000000] I'VE HACKED THE LINUX KERNEL!!!

= Motivation: university sucks real bad right now
{parent=OurBigBook.com}

The ultimate goal: create an university:
* without entry exams
* without course requirements
* where \b[all] material is <force public university teachers to publish their teaching material with an open license>[free and available online]: lecture notes, problem sheets, past exam papers
* where you only pay to take certification exams for the courses that you care about

The technical goal:
\Q[Get <university> students to write what they learn. All university material should be amazing and free!]

The how:
\Q[Create the ultimate <personal knowledge base software> with multi-user mind-melding features.]
