On the emergence of interfaces

Interfaces naturally emerge as software gets broken down into parts communicating with one another. The larger and more deliberate structures emerge from a deliberate attempt to organize the development process itself. [fn:Liskov2008] Structure often emerge directly from division of labor: as teams take on independent tasks, interfaces are established betweeen domains they become responsible for. (Conway’s Law)

Software developers are responsible for systems built out of very small atoms while ultimately performing tasks for their users of a much greater magnitude. Dijkstra showed this by computing the ratio between grains of time at the lowest and largest atoms of the system (from say, CPU instructions to a human interaction with the system) The span was already quite large by Dijkstra’s time, of about 10^9. Today this ratio would be at least above 10^12 (see grain ratios)

This large span has to be manage

Helpful linux tips

Handy aliases I always type again:

alias sai='sudo apt install -y'
alias sas='sudo apt-cache search'
alias gc="git clone"
alias sshhugo="sshpass -p 'mypass' ssh myserver.com"
alias psqlacme="PGPASSWORD=acmepass psql -h localhost -U acme acmedb"

Quick setup Postgres 10 on Ubuntu 18.10

Paste this into your terminal, replacing acme with your project name:

PGUSER=acme
PGPASS=acmepass
PGDB=acmedb

sudo apt-get install postgres

LIBRARY WRITING REFERENCE LIST
===============================
1.) Designing and Evaluating Reusable Components (Casey Muratori: http://mollyrocket.com/casey/stream_0028.html)
----------------------------------------------------------------------------------------------------------------
_THE_ reference on API design up to this day on the internet. Nobody should write a library without having seen this.
I come back to this talk every N number of weeks it is that good.

2.) stb_howto (Sean Barrett: https://github.com/nothings/stb/blob/master/docs/stb_howto.txt)
