Rough Post - Styles of Pair Programming

This post is probably a little rough, but I wanted to get it out, so here it is:


Fowler’s article on pair programming lists four "styles" of pair programming:

  • Driver and Navigator

  • Ping Pong

  • Strong-Style Pairing

  • Pair Development


and then goes on to throw out Pair Development as not being a style. Ping-Pong to me is totally a different style from anything else. There are also "Evil Pair Partner" and “Silent Ping Pong”, which are variants of PingPong, so I'd say there are three styles related to Ping Pong.


Fowler doesn't list "Just Pairing” as a style. Likewise, I can’t see the difference between “Just Pairing” and D/N - I consider them different names for the same one style.


The rule of Strong Style from Llewellyn Falco and Clare Macrae is: "For an idea to go from your head into the computer it must go through someone else's hands". I'll restate this as "Driver may not type their own ideas; driver must only type the navigator's ideas." That sounds like D/N with a restriction, so maybe a separate style.

All that said, I’m seeing five distinct styles:


  • Driver and Navigator aka “Just Pairing”

    • Strong Style 

  • Ping Pong

    • Evil Pair Partner (more for practice, not writing prod code)

    • Silent Ping Pong (more for practice, not writing prod code)

Bangle - Next Steps

I haven’t solved the bridging issue yet, so I’ve started printing the first of two cut-down halves to see if I can glue them together seamlessly. (CA/Superglue is said to be good for this).


Here's the filament I chose. It's non-metalic PLA but looks a lot like copper:



If the result of gluing the two cut-down halves is good, I'll sand the inner diameter to make it a comfortable thing bangle, then print two full halves in copper and try gluing them. If gluing doesn't end up being a good solution, I'll have to solve the bridging issue, perhaps with supports, or with tweaking print/extrusion/fan speeds.
