We regularly get feature requests for Headless to provide a field or property that can be polled by JS frameworks to detect if Headless is active e.g. windows.isBot. Well, Headless is open source, which means anybody could build a Headless

I am the PM working on Headless. Feel free to ask questions in this thread and I will try to answer them if I can. Edit: Please also note that we have not released New Headless yet. We "merely" landed the source code.

You might also know this as PERT ( https://de.wikipedia.org/wiki/Program_evaluation_and_review_... ) I used it in the past and I think it is a good framework to discover uncertainty and make it more visible, because it m

It is progressing quite nicely. We still don't know yet when it is ready to graduate from Canary/Dev though. Lot's of stuff to do!

Great summary with a few nits! I am not aware that Edge is "stupidly fast" on startup. Safari though, is indeed currently leading the field. As you correctly outlined, V8 is indeed transitioning to a world with an interpreter+opti

According to tests it doesn't. The heap memory optimization will only trigger on mobile devices <512MB ram. The zone memory improvements shouldn't have a negative effect.

It would be interesting to get feedback how much this helped Electron. Keep in mind that this blog post is talking about V8 memory and not Chrome memory. The percentage for Chrome is obviously lower.
