Hey

I’m releasing a build tool for ruby/c++ package manager.

Wondering if I could use the name “build” for my gem.

Apparently if you yank all versions (0.0.0 :D), I can reuse the name.

3. Bandwidth isn't a problem (Bill Joy, Tom Lyon)
4. The network is secure (Bill Joy, Tom Lyon)
5. The topology won't change (Peter Deutsch)
6. The administrator will know what to do (Peter Deutsch)
7. Transport cost isn't a problem (Peter Deutsch)
8. The network is homogeneous (James Gosling)

class Other
  attr :x
end

# Pull (Ask, Instead of Tell)
self.x = other.x

# NOTE: The `other.x` retrieves a value from `other`. Therefore, it's a "query", or an "ask".
# Creates more coupling as `other` must expose a larger interface to cover all of the values
# to be pulled from it to be copied to other objects.

The Purpose of Perfection

---

They say that "perfect is the enemy of the good". It's possible that their translation from French lacks some of the nuance of the original quote, and takes some license to rationalize a work management ideology where people who make decisions are insulated from suffering the consequences of those decisions. The typical diminishing returns of a software effort are not seen as a consequence of a poor understanding of perfection. There's a science to perfection, and western industry was taken by surprise by its competitive advantage
