justajon Design for 3D-Printing

Nice article, though what I'd personally love to see is a resource where I can go from zero to actually making (basic) designs using open source tools, which can then be taken to a 3D printer and printed.

justajon Ask HN: Is Washington Post correct in saying Signal is unsecure?

If QubesOS supports Flatpaks sufficiently, then it might run the Signal Desktop app (though if you want to register a new account, you do have to have a phone number, which is also possible virtually these days anyway)

justajon Closing the Chapter on OpenH264

I have considered, but so far there's no other hardware which has this form-factor with Libreboot support (although I'm unsure whether the X230 has x265 hw accel)

justajon Closing the Chapter on OpenH264

I'll continue to use h264 because it has hardware acceleration on my Thinkpad X220, whereas x265 doesn't enjoy the same luxuries on this laptop.

justajon Use Long Options in Scripts

Nor does OpenBSD for that matter.

justajon Finland's National Allergy Program Successfully Reduces Allergic Diseases

I suppose as with everything, there's supposed to be some kind of balance / ideal set of circumstances.

And yes, I mistakenly added an extra 0.

justajon Finland's National Allergy Program Successfully Reduces Allergic Diseases

For me this link results in a 503

I've read the gist of this article in my local news org feed. What it basically comes down to is that Finnish scientists noticed that Russian children who grew up in rural areas usually had way less asthma cases than Finnish city children, and thus began to research why this was the case. They hypothesized that early (first 10000 days) exposure to micro-organisms might play a key role in training the immune system not to over-react to (harmless) micro-organisms later on in life, and thus "train" the immune system better. Their hypothesis now seems to have been validated.

Basically this comes down to the hunch I had for quite a long time: Isolating children into an almost clinical environment is not a great way to boost the immune system. This might explain why there are so many people with allergies. People living too cleanly and not getting exposed to (benevolent) micro-organisms so that their immune system prepares them when exposed to later in life. I think that's one of the reasons that kids that are around pets early in life usually have lower risk of developing allergies later on.

The reasoning went like this: We've spent most of our evolution in caves digging in dirt, and now (relatively) recently we have been transported into an environment where we can pretty much have the cleanest settings. What do you think this will do to our immune system?

justajon OpenBSD Innovations

This looks quite concerning: https://isopenbsdsecu.re/mitigations/packages/

justajon DeaDBeeF: The Ultimate Music Player

I do too, but I found that it doesn't quite work well with stuff like .cue files the way it works with individual files.

With individual files I can at least (in console for example) `cycle-values keep-open always`, which makes mpv not continue to the next file after finishing the current file, however, it doesn't work when a chapter of a .cue file has finished, thus continuing on.

justajon Musk-led group makes $97B bid for control of OpenAI

I'd rather not. I can view threads on Nitter instances without enabling JS.

justajon French train passenger fined €150 for using phone on speaker

Wouldn't it be equivalent to adjust / turn down the speaker volume on the phone?

justajon French train passenger fined €150 for using phone on speaker

Playing the devil's advocate here, but what would be the difference between talking on a phone via loudspeaker vs. (loudly) talking with another person sitting next to you?

justajon Show HN: NotepadJs – A cross-platform love letter to Notepad

...or you could bundle this Notepadjs as an Electron app and subsequently install it via Flatpak (if you're on Linux)

(I'm only half-kidding)

justajon Half-Life 2: 20th Anniversary Update

That's really nice. This is what I would call a great value-add through goodwill directed at the community. I hope to do something similar if I ever get to run an enterprise.

justajon Half-Life 2: 20th Anniversary Update

So if I already own HL2, that means I'd automatically be able to access those sequels / episodes?

justajon My Social Anxiety Cheatsheet for Mingling

Does anyone have success in archiving this article into the Wayback Machine?

justajon You-get: Dumb downloader that scrapes the web

I don't think it's necessarily about fixing those bugs, but I think a lot of times it's more about at least having those bugs be documented in order to raise awareness on (probable) issues down the line for whoever would want to use that project in the future.

justajon With more legal action on the horizon, how long before Archive.org closes?

Warning: (Google) CAPTCHA wall.

justajon Code Smarter, Not Harder: Developing with Cursor and Claude Sonnet

For POSIX sh it generates kind of ugly and unnecessarily complex scripts.

justajon Is Telegram really an encrypted messaging app?

Ah right. Yeah I keep forgetting that there are other clients beside the ones by Element because none which I initially tried were as fully featured as the Element ones.

justajon Is Telegram really an encrypted messaging app?

In Matrix all PM rooms are E2EE by default.

For public rooms however, it doesn't really make sense to enable E2EE.

justajon Show HN: Ruroco – like port knocking, but better

Very unfortunate.

http://www.thoughtcrime.org/software/knockknock/ has been excluded from the Wayback Machine, and archive.is is captchawalled.

justajon Google removed Organic Maps from the Play Store

> Humans will always be humans, independently of the platform. :-P

While true, I'd much rather read discussions on HN than say X or even Reddit these days.

justajon Bitcoin Investors Buy Puts Aggressively

But division is not the same as addition.

If MS issues new shares, they will increase the total amount of shares. If you divide one BTC into smaller parts, it doesn't mean that the total amount of BTC has increased.

justajon Framework is looking for Linux Community Ambassadors

I'd much rather see Libreboot support tbh.

justajon FUTO Keyboard

Try being in 200+ rooms / spaces and using Element Web on an i7-2640M

Hint: It's not a fun experience.
