Last active October 3, 2018 06:44
Adam Klein Submissions for https://reactiveconf.com/ 2018

In fact - it's quite easy to write bad code with Redux, as I've seen many times.
In this talk I will show some bad practices and techniques with Redux, and how to avoid them.

Introduction to BDSM - ReactiveConf Lightning talk proposal

This is a proposal for a ⚡lightning talk at the Reactive 2016 conference.

🌟Star this gist if you want to see it on the conference.

Introduction to BDSM

Every day we work with multiple teams to build our products, communication and sync are key factors to deliver your product on time without compromising quality.

In this talk I will introduce BDSM a new mocking tool that will change the way you coordinate between client and server teams minimizing friction allowing each team to work at its own pace while keeping in sync.

rename whole directories while preserving the git history #git

Did you know...

...that git lets you move and rename whole directories while preserving the git history of those files?

If you run

git read-tree --prefix=$NEW_PATH -u master:$OLD_PATH
rm -rf $OLD_PATH
# ...you probably want to change some imports...
git commit -m $MESSAGE
