Python installation guide

These are my notes, not a generic solution. They are not meant to work anywhere outside my machines. Update version numbers to whatever are the current ones while you do this.

Install asdf and its python plugin, then install Python

asdf lives in https://github.com/asdf-vm/asdf

Follow its installation instructions, which at the moment of writing were:

Dealing with secrets

GNOME comes with libsecret. You can use libsecret to store your git credentials:

sudo apt install libsecret-1-0 libsecret-1-dev libglib2.0-dev
sudo make --directory=/usr/share/doc/git/contrib/credential/libsecret
git config --global credential.helper /usr/share/doc/git/contrib/credential/libsecret/git-credential-libsecret

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

Vue.js: v-model vs. v-bind:<propname>.sync

These examples use the expression foo as the data source in the parent.

	Prop name	Event name
v-model="foo"	value by default	input by default
v-bind:<propname>.sync="foo"	arbitrary	update:<propname>
