Notes from "Good to Great" by Jim Collins

These are notes from the book "Good to Great" by Jim Collins

They are not sorted in any particular order. I would strongly recommend the whole book to any tech leader, because these notes are highly contextul to myself and the current phase in my journey.

As one of my favorite professors once said, “The best students are those who never quite believe their professors.” True enough. But he also said, “One ought not to reject the data merely because one does not like what the data implies.” I offer everything herein for your thoughtful consideration, not blind acceptance. You’re the judge and jury.


To use an analogy, the “Leadership is the answer to everything” perspective is the modern equivalent of the “God is the answer to everything” perspective that held back our scientific understanding of the physical world in the Dark Ages. In the 1500s, people ascribed all events they didn’t understand to God. Why did the crops fail? God did it. Why did we have an earthquake? God d

Robot Warehouse

We have installed a robot in our warehouse and now we need to be able to send it commands to control it. We need you to implement the control mechanism.

For convenience the robot moves along a grid in the roof of the warehouse and we have made sure that all of our warehouses are built so that the dimensions of the grid are 10 by 10. We've also made sure that all our warehouses are aligned along north-south and east-west axes.

All of the commands to the robot consist of a single capital letter and different commands are dilineated by whitespace.

Part One

"""Measure time used.
# Setup timer

Scala For the Impatient 2nd Edition - Excercises
  1. Set up a map of prices for a number of gizmos that you covet. Then produce a second map with the same keys and the prices at a 10 percent discount.

  2. Write a program that reads words from a file. Use a mutable map to count how often each word appears. To read the words, simplyy use a java.utils.Scanner:

val in = new java.util.Scanner(new"myFile.txt"))
while (in.hasNext()) *process*

Or look at Chapter 9 for a Scalesque way.

Asyncio + aiohttp DevCru sample.
IO-bound concurrency with asyncio and aiohttp.
Rewritten from the previous approach that was using gevent, due to which conflicted with

`gevent` allows to create pools to manage greenlets.
