    My first reaction to this before clicking the link: why would anyone want a programmable timer?

    After clicking the link and seeing the demo: man, I’ve always wanted a programmable timer.

    This is awesome, can see myself using this for workouts and focus sessions. Thank you for sharing.

    I love the declarative syntax, and it makes me wonder if there is a use case for a timeline-based scripting language.

    Functions, variables, data structures... Intervals (timers) as a first-class citizen - an actual keyword "timer"[1] that works like const or let.

    Anyway, this is really cool.

    Oh that's pretty cool! I also like how you can bookmark timers to save them and then keep a list of them for various activities/purposes.

    Also when I saw the HN post I knew something was familiar and I remembered an old project of yours: x[it]!

    From time to time I still think about that one. Are you still engaging with x[it] or have you moved on in a sense?

More from this day
