Happy to hear! It doesn't replace healthy bedtime routines of course, and it's halfway between an experiment and a joke, but still... :)

No, not at all, but sometimes we need all the help we can get

That's interesting. How would you explain that for someone works then? At least on me, the loader does not trigger vigilance and temporal monitoring (I think). Instead, it "allows" my brain to focus on something else, which gets boring very soon, but that at the same is engaging enough to keep doing it. This kind of interactive yet very slow dynamic helps me stop trains of thoughts and relax.

It does not replace healthy bedtime routines of course, and it never meant to be a serious sleeping aid, but more of an experiment - and partially a joke. Maybe the premise should have been to help stop a spinning mind rather than to fall asleep...


The skeleton provided by ChatGPT to get the page to load fullscreen as a PWA included it, so I just kept it. “Maybe in future”... But it’s unnecessary, I should have removed it.

Feel free to send a PR! But let's parametrize the animal :)

Exactly, I made a mistake when writing it down. Thanks to the original commenter for catching it and for your suggestion!

I’ve now updated it to: "As you go through the story, the time the loader spins increases while the speed at which the text appears decreases"


Oh yes, absolutely. It bothers me as well, and it strains the eyes, but you know... for such a toy project I half vibe-coded in an hour or so I didn’t bother too much. I agree it should be improved!

It could definitely be a fun exercise. Also maybe just rendering all the text in the same color as the background and then changing the colors of the characters one by one could be an interesting option (just thought about it), but I think yours would render better.

As a side note, I have to say that posting something as simple as this, where you can’t really get too attached to the project and can read feedback in a truly neutral way - instead of just pretending - is so refreshing...

Thanks for your comment!


I came up with this one night when I couldn’t fall asleep and was looking (waiting) for some data analysis results on a web platform, noticing that the spinner was actually making me sleepy.

I guess that when the brain is engaged in an activity, and that activity becomes boring, it creates good conditions for falling asleep.

Hi HN, I’m looking for my next challenge. I’m a hybrid profile somewhere between a software engineer, a scientist, and an entrepreneur.

I’ve worked at CERN, in startups and scaleups, and at international research centres. I’ve also co-founded a startup and participated in Entrepreneurs First. I’ve led teams and owned technical and product roadmaps end to end.

I’m primarily interested in lead roles and above (Staff/Principal/Lead/Head), including founding or early technical leadership roles, with substantial ownership and high agency, where I can define strategy and execute it. I’m particularly effective in interdisciplinary, cross-field, and ambiguous environments, where I can leverage my zig-zag career path to act as a force multiplier.

I’m also open to senior IC roles in areas where I’m particularly strong and can be a “10x”: time series, anomaly detection, and making HPC easier to use.

If you have anything for me, I look forward to hearing from you!


Just found a strange switch on a CD burning app (Burn-OSX) which stated: "Pre-emphasis of 50/15μs". Turned out to be a historical hidden gem, aimed at "boosting the signal (especially the higher frequencies) in the recording before it was put onto CD, and embedding flags in the disc's subcode to tell a CD player to apply de-emphasis on playback. Some CD players even had a de-emphasis button that could be used to manually apply de-emphasis".


This example is so right. Including the parallel with what happened with those two aircrafts.
