- UVA, uHunt, uDebug
- Microcomputer, minicomputer, mainframe
- microcomputer is based on a microprocessor chip. The systems performance tends to bottleneck at the I/O pins of the proccessor chip(s). When they are saturated, the system cannot go any faster. Caches and predictive sopecultion can reduce this occurrence.
- Minicomputers have the processing spread across multiple boards plugged into a bus. When this bus becomes saturated, progress stops.
- Mainframes are designed as separate modules (compute, memory, disk, ...). Modules are connected by I/O channels. When a channel becomes saturated, additional channels can be added or additional modules communicating over additional channels can help alleviate the load issues.

- Richard Stallman
- Fundamental idea: Free as in beer
In a nutshell, the word "free" has a couple of meanings and it's not always possible to tell in context which one the user meant. "Free as in beer" refers to the cost (i.e. money) of the software, while "free as in speech" refers to what you are allowed to do with the software.

A refund for defective software might be nice, except it would bankrupt the entire software industry in the first year. - Notion of "intelligent design", as applied to software
- Isolate components from each other so that they cannot interfere with each other - or even communicate unless there is a reason to do so
- Stick to the "principle of least authority"; no component should have more privilege than it needs to get the job done
- The failure of one component should not cause others to fail
- The health of components should be monitored; if one stops operating properly, the system should know about it
- One must be prepared to replace components in a running system
