We started by
We continued by

Where should I begin?
WHAT IS MOST IMPORTANT?
Why does this matter?
Focus on the story that you are telling
- What questions are you answering?
- Which part of the system are you describing?
- What is the correlation between various elements shown?
Let me share a story about memory
Out of 1,000 issues
200 are about memory
Start by counting the right memory
Improve memory allocators defaults
Make it easy to improve,
so that improving is easy,
and so that anyone can do it

What is most important?
WHY DOES THIS MATTER?
An increasing number of people
depend on the software
that you develop.
Make it understandable,
simple to work with,
and predictable.
Software is means to an end,
it’s not an end in itself.
You are not alone, first or last.
Learn from others, and pass it on,
like I am doing now.
That’s what makes nice things
And builds healthy ecosystems
Maybe learn more this coming Thursday
