What matters in developer experience varies as your business grows. @PhillipaAvery from @netflix #QConPlus Startup, Growth, maturity, and renewal-or-decline pictured a
@PhillipaAvery @netflix In the Startup and Growth phases, it's all about velocity. In Maturity, it gets interesting. We need stability without killing velocity.
@PhillipaAvery @netflix In renewal/decline, parts of the software need stability while other parts need velocity.
(I missed the cool picture, it was pretty great)
In the Beginning of Netflix, any developer could use any IDE they wanted.

As they grew, they found it valuable to find a recommended IDE, with provided licenses and custom plugins created as useful.

@PhillipaAvery
Netflix is still on multi-repo, rather than monorepo. This helps with velocity of each repository.

"The larger the repository, the bigger hit to velocity"

But there are problems that wouldn't happen in a monorepo.

Build v buy: "Will building internally create a divergence from the industry 'cutting edge' technologies?"

Ya gotta maintain a relationship with the open-source community. Influence, contribute back.

"The future of developer experience that you can start using right now: devcontainers"
@avdi gets specific at #QConPlus
@avdi Why are containers better for development than other forms of virtualization?
Because they aren't virtualization.

In the right circumstances, development can proceed at native speeds on ordinary computers.

@avdi #QConPlus
@avdi A devcontainer is like the ramen noodles of onboarding to a project: just add hot water and you're ready to go.

Today at #QConPlus , @girba shows graphs that reveal hidden dependencies in code.
Somehow this code reveals its own properties and relationships in custom-made developer experiences

"empowering developers to create their own tools for every one of their problems" @girba #QConPlus

This is a superpower of developers: we can craft our own work environment.
For example, when viewing build logs: as you find a new problem, add some custom highlighting so that next time it jumps right out at you.

Anyone who says to you “this architecture is universally applicable”
is probably selling something,
and not doing a very good job at selling something.

@tlberglund #DevoxxPL
Don’t use event-driven architecture for a small system or for an exploratory spike.
“learn what you’re trying to do before you elaborate your architecture.”
@tlberglund #DevoxxPL
Databases don’t go away when you’re using events.

If nothing else: when you need lookup by multiple keys, databases are necessary views on the system of record (which is the event log).

"Work capacity is not the same as productivity."

@coda lays down the maths on limits of organizational growth and how to overcome them.

codahale.com/work-is-work/
Adding people scales at best linearly upward, at worst geometrically _downward_.

Two things you must constantly seek in order to get more done with more people:
1. "Constant pursuit of force multipliers"

Instead of adding more people to the same task, change the task to be done.
Develop more-complex internal structures, such as tooling teams that facilitate many development teams.

“The similarity of team mental models is a good predictor of team performance”

@TeamTopologies
Optimize for the team, and the benefits compound in a positive way.

@TeamTopologies

Optimize for the task and the costs compound until we are all stuck in mud.
See the team as the fundamental unit of delivery.

Build an API surrounding each team [to other teams and the wider organization.]

It's a holiday, I get to do what I want, so let's see what else is in the CSS 2.1 Spec!

It's time for backgrounds and fonts...
background-color is a friendly property. Use it even when you also specify the image, in case the image doesn't load/hasn't loaded.
Defaults to 'transparent' so the stuff behind it shows through.

The background fills the margins and the borders. (It shows under dashed borders)
background-image: url("where-is-it.jpg")
makes a picture show.

How big the picture is depends on the intrinsic properties of the image (width, height, ratio). Anybody know how to find out whether an image file has these?
