gorbypark··on Python client for the $20 Colmi R02 smart ring
They do exist, I believe. I don't have one but came across many for sale on AliExpress when looking for a writer to clone my RFID apartment door entry thingy. Seems like they even have some that are dual NFC/RFID that would work as regular NFC as well as for my apartment door (125khz).
gorbypark··on Show HN: One – A new React framework unifying web, native and local-first
From my limited understanding of Vite, it serves es modules directly on the fly during dev but uses Rollup to bundle in production. Did you swap out Rollup for Metro in production, or have you somehow ported all that byte code generation stuff to Rollup as well? Pretty wild either way!
gorbypark··on Show HN: One – A new React framework unifying web, native and local-first
As a react native dev I’d love to hear some of the implementation details!

First, is this a whole new router? Is it based on expo-router, or is it sitting on top of react-navigation? Maybe all new with react-native-screens as a foundation?

As far as Vite goes, I assume this is only on the web? Metro is still be used on the native side? If true any reason why you’re not using metro on the web as well (I’m kinda partial to having all platforms as similar as possible, tooling wise)?

I suppose I should also ask how expo fits into this all…meta framework on top of expo or something “all new” on stock react native?

gorbypark··on Automattic–WP Engine Term Sheet
I mean I guess using "WP" in their business name is kinda pushing it I guess, but offering Wordpress hosting while using the word "Wordpress" is fair game (IMO). A company can't/shouldn't be able to tell someone they can't use the trademark name in describing the service another company offers. How would that even work? "We offer hosting for the project that 80% of the websites in the world use!". If Wordpress (the project/company) allows someone to offer hosting of that project (ie: it's not a mongo type licence), they can't expect someone to not even use the name of the project they are offering hosting for.

Imagine if Linus prevented companies from saying they offer hosting using Linux.

gorbypark··on Discord Reduced WebSocket Traffic by 40%
The deb file probably contains new versions of electron (or at least versions of electron that change the actual v8/chrome version) and the regular updates during launch are loading JavaScript. Just a guess.
gorbypark··on Real-time Linux is officially part of the kernel
Came here to say basically the same thing. Linux CNC on an old PC with a parallel port can do some amazing things!
gorbypark··on AT&T's Hobbit Microprocessor (2023)
Of course it depends on the model and the condition, but somewhere around or under 5-600 euros?

I dream of owning one of those one day! I was a huge BeOS fan as a teenager, and even though the BeBox was from before my time I’d love to own one! They very very rarely seem to come up for sale, though. And the ones that do are pretty crazily priced..
gorbypark··on Apple announces the iPhone 16 with a faster processor and camera control button
turns out it's both! seems like a physical microswitch for taking a photo with the button itself also being capacitive and they are using haptics for the "half press" feature (as well as touch sensitivity, slide between modes, etc).
gorbypark··on Apple announces the iPhone 16 with a faster processor and camera control button
Most likely it is capacitive and doesn’t actually move and they are using the haptics engine to make it feel like a button. It works surprisingly well on the iPhone SE with Touch ID. You can’t even really tell that it’s not actually moving when you press it.
gorbypark··on Show HN: OBS Live-streaming with 120ms latency
They mention "$1 per 1000 minutes of video delivered", does that mean per viewer? $0.06 per hour per viewer seems like a lot, although I have no idea if that's "competitive" or inline with actual bandwidth costs.
gorbypark··on Show HN: OBS Live-streaming with 120ms latency
I think state of the art in this space is WHIP/WHEP, which is what this project is implementing. I'm guessing 100k+ clients would be pretty difficult for Broadcast Box (out of the box), however Cloudflare has a beta stream service that's has a tagline of "Sub-second latency live streaming (using WHIP) and playback (using WHEP) to unlimited concurrent viewers." https://developers.cloudflare.com/stream/webrtc-beta/
gorbypark··on Show HN: OBS Live-streaming with 120ms latency
Having discovered this 15 minutes ago I can't really speak in absolutes, but firing up OBS and using their test server, I think this would allow you to do exactly what you want. It's trivial to get OBS set up to stream to this, and while I haven't tried it, the docs say that it supports multiple streams to the same stream key. I guess it would just show each stream side by side in the client?

I think you could run your own server, run an instance of the front end and distribute the instructions to setup OBS to your family.

gorbypark··on European iPhones are more fun now
It’s definitely at least partially tied to the Apple account location and just not physical location. I’m a Canadian and have been living in Europe for three years now and don’t get any of these new Europe only features. I’m guessing because my Apple account is still tied to Canada / I use a Canadian credit card on it.
gorbypark··on FakeTraveler: Fake where your phone is located (Mock location for Android)
Fair, I took your original comment to mean that Google was mapping WiFI AP locations using people's phones (which could still be true). However, after re-reading it I see you meant that Google is pin-pointing your own location based on which AP's are visible.
gorbypark··on FakeTraveler: Fake where your phone is located (Mock location for Android)
At one point in time the Google street view vehicles were logging wifi position data as well. I don’t know if they still do it, though.
gorbypark··on What is Toybox?
Toybox combines many common Linux command line utilities together into a single BSD-licensed executable. It's simple, small, fast, and reasonably standards-compliant (POSIX-2008 and LSB 4.1).
gorbypark··on Do Skis Get Blunt?
It totally depends on the type of skier and the type of skis you have. I worked in the ski industry and thus lived and worked in ski towns for 15 years. If you are a ski racer, tuning edges matter. If you aggressively ride groomers all day, then they will matter. Riding big fat powder skis everyday, inside and outside of the resort? More or less doesn't matter. Are you a park rat that only ever skis the park? Those folks will actually detune their edges on purpose.

If you are a beginner / intermediate skier (someone who never to rarely carves a ski), edges on the blunter side of things can actually help you out. Sure, it's a bit more sketchy on ice, however just doing a "slide turn" is going to be much easier. It will take less force to make your skis point where you want them too, making you much more confident. It's one of the reasons they put beginners on smaller skis. Less edge = easier turning.

I have skis that were kept dry and haven't been sharpened in years and ski perfectly fine and it's exactly how I want them.

gorbypark··on Pumped-storage hydroelectricity
Using google translate, it shows they are planning on upgrading the reservoir to 1 million cubic meters, which is about 264 million gallons from ~58 and that it will fill 3 times a year naturally, 4 times with pumps. 1/3 will be used to just keep the river flowing down the mountain, 1/3 for snowmaking and 1/3 for electrical generation.

Some extremely back of the napkin math (using ChatGPT) shows that if 1.33 million cubic meters of water per year were used at 1000psi (this is a huge assumption) to generate electricity, at the standard 80% efficiency you could do 2,030 MWh per year. A random search for the average price of electricity in Switzerland shows 0.154 euros per kWh, so it seems like this could potentially generate 312,620 euros (at consumer rates...) worth of electricity per year. Given that the idea of pumped hydro is to pump when electricity is cheap and then generate at peak demands...I'm not quite sure how to do that math!

gorbypark··on Pumped-storage hydroelectricity
The only problem of 3000 PSI is 99% of the snowmaking pipelines out there would instantly blow up at that pressure :)

You would also need to have PRVs anyways, because anything above about 700psi (900 if you are pushing it) is unusable/unsafe to use by the actual snowmakers and equipment. You also run soft 2" "fire" hose from a hydrant to a gun, and those are not rated for those pressures and the nozzles of the snow guns would wear out super quick as well (and the internal plumbing of the gun would probably blow up too).

You'd generally have a max of about 900 PSI and ideally much lower as most of these pipes are relatively old, have no maintenance (until they blow up and a quick patch is made) and were welded up by "Bob the maintenance guy"!

I suppose you could design a brand new system to be capable of such pressures when run in "generation" mode and still have some PRVs to keep it at a usable pressure during snowmaking operations.

gorbypark··on Pumped-storage hydroelectricity
I worked in the snowmaking industry at ski resorts for more than a decade before getting into tech. Many ski resorts have a snowmaking reservoir at elevation and a pumping system to fill it (usually off peak) and then use gravity to actually feed the snowmaking guns (at least partially). Almost every snowmaking manager (that I talked to) has had the idea at some point to try some sort of pumped hydro offset, but I'm unaware of anyone who has actually tried it. It would be fairly small scale (reservoirs can be ~20 million gallons, usually less) but it would be interesting to see the economics of it because the infrastructure is already there (pumps, pipes, reservoirs, etc). The systems generally even sit unused for 7-8 months of the year.

I think some of the challenges are that while most resorts have a fairly massive pumping system, it's usually geared towards slowly filling the reservoir, with the rest direct feeding the snow guns. Not many places have the need to fill a 20 million gallon reservoir in a couple of days.

There's also the probability that the head pressure's wouldn't work out. Gravity feeding from an upper reservoir near the top of a large mountain can result in thousands of PSI at the bottom if not passed through a series of pressure relief valves. I'd imagine ideally you would have to build a generating station and a new catch reservoir at the perfect elevation because if you are pumping a lot higher than needed the efficiency is going to drop significantly.

gorbypark··on Anthropic Introduces Claude Projects
I think the first step is to have a .claudeignore file (or maybe we can standardize on .llmignore) to tell it which files you don’t want it to add to the context. You could easily eliminate millions of tokens by ignore node_modules in most JavaScript projects!
gorbypark··on FAA investigating how counterfeit titanium got into Boeing and Airbus jets
I am guessing that it was real titanium, just a different grade/alloy/treating process being passed off as something it was not or it's possible it's even the same quality/grade, just of unknown provenance (fell off the back of a truck) and its documents were forged. Seems kinda likely as Boeing says (as I understand from the article) they have tested the parts and it's the correct grade of titanium.
gorbypark··on Battery-swap networks are preventing emergency blackouts
This sounds like what I remember it being described as. Thanks!
gorbypark··on Battery-swap networks are preventing emergency blackouts
Once upon a time (~15 years ago!), I worked at a ski resort in New Zealand that had a fancy new "automated" snowmaking system. When all 200 (give or take) snow guns were running, along with the required water pumps/air compressors, the system could draw megawatts of power. Generally it didn't get below zero very often in the closest city to the resort (Queenstown), but when it did, people would turn on their electric heaters, and demand would go through the roof. The way it was explained to me is that the power company actually sent a signal through the power supply which would trigger our snowmaking system to shut itself off. It was pretty cool to see and also infuriating, because of course you can make much more snow when it's cold.

Being a giant nerd I of course asked if this was really happening via some network connection, but I was told they actually modulated the frequency of the entire grid in a very small, but predictable way. Some sort of device sat there and when it picked up the pattern in the frequency changes it would then trigger the shutdown.

I've spent a while doing some searches about such a system but couldn't find any information. Anyways, your comment about demand management made me think of this and how it's been possible in one way or another for a long time (albeit not milliseconds!).

gorbypark··on Blackmagic Cine Immersive Capture for Vision Pro 8160x7200 Resolution per Eye
Agreed, and in my opinion, Apple messed up with the Vision Pro with this. They took the battery and made it external, yet the head unit itself is heavier than most battery-included head units! IMO they should have made the compute unit external as well (you already have to have a brick attached via a cable, it's madness not to (technical details aside, potential added latency, etc)). I don't really know the details and I'm sure someone has weighed all the components...but if the processing was not in the head unit, they ditched the external facing display + glass screen cover, and went all in on being light weight (maybe a carbon frame vs aluminum? not sure how much that would save), it would be much more enjoyable.

Obviously the Vision Pro in a glasses format isn't possible now. However, the Vision Pro with a few hundred grams shaved off of it, plus being a little bit less "horizontally" bulky would result in a much more enjoyable user experience.

gorbypark··on Starship's Fourth Flight Test [video]
If you have an Apple TV (or possibly also Android TV?) it's quite easy with the tvOS VLC app. The top comment here posted the stream link, https://prod-ec-us-west-2.video.pscp.tv/Transcoding/v1/hls/G... Just paste that into the network stream option in the tvOS VLC app and bam, good to go. It's really kinda magical with an iPhone, as you can just paste the link into the popup on your phone!
gorbypark··on Apple Silicon MacBook batteries can't be replaced under warranty by third party
My laptop is plugged in most of the time and I use a menu bar app called "Al Dente" that sets the max charge at a certain value (I set 80%). I'm hoping this will help with battery longevity, however I have no real idea if it will. My iPhone it will cap charging at 80% sometimes until the morning to help prevent the battery being at 100% for too long, so I figured 80% was a good number for the MacBook as well.
gorbypark··on Signal: Will leave the EU market rather than undermine our privacy guarantees
Right. That is the OPs point, however (as far as I can tell). They think it will be intentionally abused by governments as a way of collecting data by mandating certain hashes that will intentionally have many collisions.
gorbypark··on Signal: Will leave the EU market rather than undermine our privacy guarantees
I think OP is saying that the algorithm is designed in such a way it can match “visually similar” photos/content. The idea is you can’t just rescale, crop or otherwise slightly change a photo as you could if this was just a regular SHA hash of the file. Now they are saying that it might be possible to create an “evil hash” of a document that could match a large percentage of documents, because the hash algorithm obviously doesn’t have enough bits to actually represent the content. So if you have a hash of “white document with some black text” (for example, if looking for image scans of documents) and add this to the db of “watched” hashes, you could in theory hoover up documents.

A quick search didn’t lead me to any proof of concepts about this idea but on the surface (I don’t have any knowledge of the hashing algorithm used in these content filters) it seems like a plausible idea, depending on a lot of factors.
