I wouldn't say proglangs are rules. Rather, they are a language of instructions to the machine; the language can often be converted to machine instructions through a tool (often a compiler).

Class contradictions of course have an impact.

I think the UNIX philosophy hold some communist values:

• A communal interface for programs and scripts should exist to reduce redundant code.
• Programs should not have private property (or internal code) when unneccessary.
• I think that the "Test prototypes often" is a result idea from the cold war era. Heavy testing was neccessary to ensure that programs functioned properly.

The UNIX philosophy was born in an environment with a lack of surplus; likewise, the primal environment neccessitated communism in humans due to the lack of surplus.

Also, it's interesting that computers could technically be described in DiaMat.

• Voltage changes form a principal contradiction between states. (Typically a binary state.)
• Electrical circuits form base contradictions in some way.

These two 'principal' contradiction form the base for a higher-level contradiction:

• A contradiction between the setter/retriever (CPU) and Memory.
