There is another fundamental idea that we all need to internalize. Software is created and evolved as an incremental continuous process, where each new innovation is building on what somebody else invented before us. We are all very quick to build something and believe we “own” it, which is correct, if we stop at the exact code we wrote. But we build things on top of work and ideas already done, and given that the current development of IT is due to the fundamental paradigm that makes ideas and behaviors not covered by copyright, we need to accept that reimplementations are a fair process. If they don’t contain any novelty, maybe they are a lazy effort? That’s possible, yet: they are fair, and nobody is violating anything. Yet, if we want to be good citizens of the ecosystem, we should try, when replicating some work, to also evolve it, invent something new: to specialize the implementation for a lower memory footprint, or to make it more useful in certain contexts, or less buggy: the Stallman way.

The easiest possible system is that we just re-run everything. Going back to our spreadsheet, every time we update a cell, we go through every cell in the sheet and calculate its value fresh. When a cell references another cell (e.g. =B8), we first calculate the value of the dependency, then carry on calculating the initial cell’s value. Eventually, we will recursively have updated every cell in the sheet.
