My hopes are high that the EU will be able to do this some day (unless it's fully enshittified first -- see chat control, age verification etc.)

I've seen good, low-budget indie sci-fi short films that would presumably meet all of the Dogma 25 rules. So I think it doesn't protect against this category of films and neither would that be a good thing anyways. It just requires creative solutions if you want to e.g. portrait space travel.

The comment sections are perfectly fit for this purpose, too.

HN also decides what you see. Yes, it's (mostly) based on other users' upvotes, but on TikTok et al. its the same just with a different metric (watchtime, interaction, retention and probabily more). Where do you draw the line? Or do you have a different proposal how these generated feeds should work? I don't think just showing content by users you follow is going to cut it, because ideally the purpose is to show new and interesting stuff nobody in your circle was aware of.

I don't know if you can write drum sheet music with it.

I really like your editor with the transcription view. Maybe a spectrogram would be more helpful than a simple waveform display.

jmusall — Mon, 11 May 2026 08:29:52 +0000

Fun idea and also I didn't know that websites could get access to my accelerometer data. However for me the sample frequency is 50 Hz which is way too low to measure even the lowest string pitch (E2, about 82 Hz).

Could one mistake this

for a real CVE report?

How is it partisan political flamebait? While the title and opening paragraph might be exaggerated and not exactly neutral (which is even admitted right after), the rest of the article contains what looks to me like well-researched facts.

New comment by jmusall in "NIST scientists create 'any wavelength' lasers"

jmusall — Sun, 19 Apr 2026 12:48:16 +0000

Probably not because EUV gets absorbed incredibly quickly by anything other than vacuum. This is why it is created in low density gas, thin liquid or solid samples (high harmonic generation) or electron clouds (free electron laser).

New comment by jmusall in "iNaturalist"

jmusall — Fri, 03 Apr 2026 20:25:25 +0000

Haven't tried iNaturalist yet, but I love Merlin Bird ID [1] and Flora Incognita [2]. The latter seems to be exceptionally accurate (over 80% up to 98% depending on the dataset) [3]. They also expose an API for "registered external clients" [4], but so far I sadly wasn't able to find any further documentation on it.

A problem I often have with Merlin is that the birds seem to know when I record them, and promptly stop singing...

Not sure why it is a "template".

New comment by jmusall in "Glassworm is back: A new wave of invisible Unicode attacks hits repositories"

jmusall — Sun, 15 Mar 2026 22:22:54 +0000

Of course! I bet there are tons of ideas that didn't make it into Unicode, for better of worse. Where you draw the line is kind of arbitrary. You, personally, can of course opt out of all of that by restricting yourself to ASCII only, for example. But the rest of the world will continue to use Unicode.

New comment by jmusall in "Glassworm is back: A new wave of invisible Unicode attacks hits repositories"

jmusall — Sun, 15 Mar 2026 19:15:39 +0000

The fact is that there were so many character sets in use before Unicode because all these things were needed or at least wanted by a lot of people. Here's a great blog post by Nikita Prokopov about it: https://tonsky.me/blog/unicode/

Very cool! Do they accept external contributions, e.g. from Norwegian citizens? Also, was there any thought given to "digital souvereignty" (wondering because the repos are hosted on a US service)?

I'm also surprised that you were able to (or expected to?) use your private GitHub account for your work.

I think you could only get around this by forcing your whole dependency chain to only add non-breaking security fixes (or backport them for all versions in existence). Otherwise small changes will propagate upwards and snowball into major updates.

Then, when the stock market crashes due to software failures and timing inconsistencies, he'll want to undo it and thereby cause even more chaos ;)

jmusall — Mon, 09 Mar 2026 22:16:08 +0000

I guess the author's perspective is one of someone who has little experience with current tools/frameworks, so "ergonomics" become somewhat more important. Most of the complaints are actually about lack of documentation, not instability of interfaces.

I also liked the article especially because it avoided web apps, which I think are a subpar solution to a problem the software industry created itself by not developing more standards like W3C.

Then nobody would admit it, so the problem persists. Except maybe for fully automated accounts. Those should of course be banned anyways.

jmusall — Sun, 08 Mar 2026 21:11:38 +0000

My comment wasn't supposed to be whataboutism, but I can see why it comes across like that. What I was trying to say is that I think we shouldn't judge all of these things independently of each other. So if you really want to be consistent, you'd either have to come to the conclusion that this particular example isn't as horrible as it initially feels, or go vegan, never buy leather, etc.

I also agree, the horrors of the tech domain are usually much more subtle and indirect.
