Time Travel refers to the ability to record a tab and later replay it ([WebReplay][wrr]). The technology is useful for local development, where you might want to:
pause and step forwards or backwards
pause and rewind to a prior state
rewind to the time a console message was logged
rewind to the time an element had a certain style or layout
Principles we use to write CSS for modern browsers
Recently CSS has got a lot of negativity. But I would like to defend it and show, that with good naming convention CSS works pretty well.
My 3 developers team has just developed React.js application with 7668 lines of CSS (and just 2 !important).
During one year of development we had 0 issues with CSS. No refactoring typos, no style leaks, no performance problems, possibly, it is the most stable part of our application.
Here are main principles we use to write CSS for modern (IE11+) browsers:
Stuff I wish I'd known sooner about service workers
Stuff I wish I'd known sooner about service workers
I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.
I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.
Use Canary for development instead of Chrome stable
Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.
Who pays when startup employees keep their equity?
Who pays when startup employees keep their equity?
JD Maturen, 2016/07/05, San Francisco, CA
As has been much discussed, stock options as used today are not a practical or reliable way of compensating employees of fast growing startups. With an often high strike price, a large tax burden on execution due to AMT, and a 90 day execution window after leaving the company many share options are left unexecuted.
There have been a variety of proposed modifications to how equity is distributed to address these issues for individual employees. However, there hasn't been much discussion of how these modifications will change overall ownership dynamics of startups. In this post we'll dive into the situation as it stands today where there is very near 100% equity loss when employees leave companies pre-exit and then we'll look at what would happen if there were instead a 0% loss rate.
What we'll see is that employees gain nearly 3-fold, while both founders and investors – particularly early investors – get dilute

I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:
The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't
