People keep talking about blimps, but they neglect the price of helium which is rising.

#422I was curious about how people with seizure disorders safely click links not knowing what lies ahead. Investigating the current best practices for building for epileptics, using this great resource (1) as my starting point. This took me down a rabbit hole on current methods to detect seizure onset... I came across a very interesting journal article on applying ML in an implantable that can detect seizures within 3 se…
Apple also worked on reducing seizures:

I live in a suburb of Stockholm and it is like that, every neighborhood having its own ice rink, some are inhouse and some are opened, mostly free for use and divided for hours with and without hockey clubs.
That sounds so freaking cool. I cannot imagine such a world. I bet it also does a lot to bring the community together. In my area there was practically nothing, but recently a bunch of things got built like walking paths connecting the neighborhoods, a school, sports centers, a park not too far away...etc. I think it had an overwhelmingly positive impact on the community and only some of it came from tax dollars too.
Sports in general is a big thing here in Sweden and the same way it comes only partially from tax payers' money, a lot of those activities are supported by the community and participants

I got my first intro to milk punch from How To Drink: https://youtu.be/zr8dtT9siq4?si=akpHbgmLrtIcgXJk I originally used their spec, but have since learned milk punch is pretty forgiving. It works really well for complex flavors that have a lot of tannins or volatile constituents (tea, wine, citrus, etc). I’ve found good black tea and a deep, sweet port tends to be a winning combination. Done correctly, the resulting…
I’d never heard of milk punch, had to look that up. And now I have my own new rabbit hole! Much thanks!
Be warned that getting good clarity takes time and persistence if you’re going the coffee filter method. You’ll also get better flavor if you let the solution sit for up to a day before filtering. Enjoy!

If you don't know about Plasticity 3D, you should know about Plasticity 3D. It is different, but still parametric, and CADish.
Thank you for this! I was completely unaware that it was out there, and I really dig a lot of what the creator is going for. For example, I'm not a Blender user but lots of people are, so the idea that he created a WebSockets-powered real time bridge is the kind of innovation that makes the world better. However, I do have two nits. The first is the overwhelming focus on pricing model as a feature. I get it; SaaS is…
> The people screaming the loudest for free-as-in-beer CAD that doesn't suck are also likely the worst customers that you wish you didn't have.
These are often ambitious hobbyists who have quite some free time for their hobby, but little money (also since they don't earn money by using the CAD program).
The most rational choice would in my opinion to sell very cheap licenses without any support to these people: you don't loose any money because they wouldn't be customers for the expensive licenses anyway; on the other hand, because of some of these people's devotion, it makes the CAD software a possibly better choice for many companies because of the existence of more people to hire who know the software quite well.

#426I did not realize that learning Fusion 360 was going to be such a huge chapter in my current journey. Looking back, I'm kind of stumped at how I avoided it as long as I did. I would now put learning CAD in the same category of mandatory life skill as learning to code. The ability to translate what you see in your mind to something that can be repeatably fabricated is an incredible power move, akin to learning how to…
Thanks for the push to learn this as well!
Curious how you best learned how to communicate complex ideas with empathetic language?

Try recording yourself playing video games. You will quickly snap out of the illusion and realize that you're passing through life staring at a screen.
I had an unhealthy comfort meal that I couldn't kick. I filmed myself eating it and was disgusted by the sight of myself. That worked. I still eat it sometimes but in much smaller portions and not nearly as often.
Yes this is the exact effect I am aiming for. There's just something about watching yourself from a different perspective that lets you have fresh judgment on it as if it were a different person.
Re: Ask HN: What rabbit hole(s) did you dive into recently?
#428My two rabbit holes from the last ~year: JellyFin. Amazing. A little clunky here and there, so some automation is needed. Then the weird bugs - gotta get a debug instance going to see what is going on. Once you start thinking about it as a "personal Netflix" you start building out a larger collection which needs organizing. Then your friends want an account. Then you realize your satellite tuner has a streaming funct…
Try Veso, which is a Jellyfin fork: https://github.com/vesoapp/veso
Re: Ask HN: What rabbit hole(s) did you dive into recently?
#429So many great rabbit holes in this list. There are several that have blown years of my spare time. My one, at the moment is precision time keeping. Time nuts. I have a pile of oven controlled crystal oscillators, GPSs (even the full Ublox time specific LEA M8). I got a BG7TBL counter and multiple cheap GPSDOs to test my own. I have a DAC1220 20 bit DAC on an ESP32 disciplining a TCXO from an old phone base station by…
You might explore clock hardware used in the film and music industries. Ranges from $200 temperature controlled audio clocks to very expensive video black generators. Some links to get started: https://www.sweetwater.com/c953--Synchronizers https://en.wikipedia.org/wiki/Black_and_burst https://www.sweetwater.com/insync/black-burst/ https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m... Might be interesting t…
I assume my GPS disciplined over controlled crystal oscillator is going to be much the same as most of those. Short term .1milli Hz.
Without GPS, yes a rubidium oscillator would be fun to have and the phase noise is may be better than the TCXO disciplined oscillator, but the system I have with the LEA-M8T with a good external antenna and used in the 'base station surveyed in' mode is more stable. I've been keeping an eye on ebay for old one at a reasonable price. They do wear out so it's a risky buy.
The black burst stuff is funny. I used to work in TV as a kid. The plate on my car was PAL-443

#430OpenWRT, CD and DVD Players, Kindles, and OpenBSD due to some recent HN article.
I knew about most of them a little or fair bit already, but there's always something to learn the deeper you go :)
