It’s nice to see some ZK stuff on the front page. It’s not written in Go or part of Docker’s story or any other headline-grabbing thing, but it’s rock solid as these things go and is much more widely used (especially at companies with legitimate scaling problems) than you’d think from reading HN.

YMMV. Having maintained ZK clusters I would hardly call it rock solid.

Looks pretty nice overall for sure. But, I would give the feedback that the non-uniform scaling of UI controls is a very uncommon animation behavior, and will feel out of place on any OS that I’m familiar with. In general, the animations feel a bit over eager and in the “for show” tuning instead of “clarify what state transition is happening” tuning. Generally when scaling large panels like that, you’ll want to not s…

Late edit: By zero transparency, I meant zero opacity. I.e., it'll start fading as it approaches approaches 100% scale from %60 scale. And not clarify, by non-uniform scaling, I'm referring to elements stretched in the X axis more or less than they are in the Y axis.

Do you have any references to recommend for learning heuristics like this? I want to create effective, useful visualizations but it’s not my area of expertise.

The small amout of time I spent with JavaFX was productive, I wish it was more popular. It was a viable alternative to QT for cross platform desktop GUI apps, but I do get a feeling that its future is uncertain with it getting unbundled from the Oracle JDK. I don't really get why AWT and Swing get to be first class citizens of "core" Java while JavaFX which is the best approach to build GUIs in Java cannot be.

I feel exactly the same. I loved JavaFX and I sometimes dream of an alternative universe where software never went to browser and always stayed on the desktop. JavaFX might have been the king.

By design, ZK depends on continual network connections and heartbeats and it has to to provide the guarantees it provides. I wonder how much of "it is not rock solid" falls into "network flakiness" ?

Network, processes OOMing, individual machines going down because reasons. Reviving the ZK cluster each time felt like a brain surgery.
