Brief notes on Meteor for CS 294-101. Many of the key architectural ideas in Meteor are described at https://www.meteor.com/projects.

1. BSD as example of great system design. Application primitives: processes run by a scheduler, sockets, sys calls, virtual memory, mbufs. What makes something a platform. Unix vs Multics.

2. History of application architectures. Mainframes (e.g. IBM 360 / 3270), client-server (e.g. Win32), web (e.g. LAMP), cloud-client. Oscillation of where the software runs. Thin vs thick clients, data vs presentation on the wire. Changes driven by massive forces (cheap CPUs, ubiquitous internet, mobile). New architecture for each era.

3. What it takes to make modern UI/UX. Mobile. Live updating. Collaboration. No refresh button. All drive the need for “realtime” or “reactive” system. Very different from HTTP era.

4. Four questions: 1 — how do we move data around; 2 — where does it come from; 3 — where do we put it; 4 — how do we use it?

How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb
