From other anectdata the apple watch seems to just as bad as everything else.

We just don't seem to have any idea how to track sleep quality even with better devices than just a watch/whatever. Even a binary, is the person I'm attached to sleeping, is hit and miss. And with that in mind you can be pretty sure that the sleep stages etc is even worse.

Sure, but we can't do sleep tracking well. Todays devices mostly guess and map to typical patterns. Might, might not, work reasonably for you. But chances are that if you want to track your sleep because you suspect irregularities then they are about as useful as a potato.

Depends on what you mean, they have more redundancy which means that the yield can be much higher.

tjoffon Tell HN: Cloudflare silently injects its analytics when you switch nameservers

If you are self-hosting, sure. Otherwise, mostly no.

tjoffon Tell HN: Cloudflare silently injects its analytics when you switch nameservers

Truly doubt that. Sure, but if they are making a mistake due to dark patterns then it is another thing.

This thread does indicate the latter.

tjoffon Tell HN: Cloudflare silently injects its analytics when you switch nameservers

I don't buy that, there is no reason for 99.9999% of sites to use cloudflare.

The "reason" to use cloudflare is hype.

tjoffon The Ploopy A+ Trackball Is Here

Okay, sure, but that's a very narrow and specific angle though? Not sure I could deliberately rotate the ball in that direction even of I wanted to.

Especially given the limited use kensington uses rotation for (at least to my knowledge)

tjoffon The Ploopy A+ Trackball Is Here

Why does it require two sensors?

tjoffon Mistral OCR 4.1

Tesseract is super picky though often failing pixel-perfect screenshots...

So, maybe it can be tuned for your usecase but with that kind of investment €3.5 for 1000 pages is a bargain...

Yeah, that should be reserved for apple and google! /s

tjoffon Hax – a minimalist, terminal-native coding agent written in C

Well, you'd think so but given how slow and resource hungry the ones written in javascript are it makes a lot of sense.

tjoffon Docker Sandboxes – Disposable, isolated sandboxes for AI agents

Sure, but all projects are version controlled? You only mount the project dir so you can only loose your current changes - which is the same if you copy...

tjoffon Docker Sandboxes – Disposable, isolated sandboxes for AI agents

What is the advantage of copying rather than a bind-mount?

tjoffon Humans missed 1 in 3 threats approving AI agent commands across 40k game runs

the whole concept of having cars with that are almost capable of self-driving is utterly insane, the very least you'd need special training. We are not equipped to deal with something that works brilliantly most of the times but might kill you for no foreseeable reason.

tjoffon Why does Mail app contact iCloud when sending a non-iCloud email?

I don't think you have to look far nor hard for a mail-client that doesn't communicate with the developer because you send an email...

Universal Clipboard, AirDrop and iMessage - is that really the value add of apple? iMessage... do we really want to encourage that behavior?

tjoffon Bonsai: Janestreet's UI Library

It only adds discoverability for the things that fit the screen. In other words, you have to make it simple. I.e. the lazy way to make something "user-friendly", do as little as possible and force the user to adapt to your ways instead.

tjoffon My personal AI benchmark: “Generate an SVG of a frog with a Habsburg jaw”

It's not hallucination. The prompt lacks details and given that an AI or a human has some artistic freedom. After all, that is why current AI is usable at all.

tjoffon A big win for Android interoperability

So, the argument is that it is popular? I'm not arguing against that...

That people trade anything for even just perceived convenience? That isn't news either, but it does explain a lot of the sad state of affairs we are struggling with today.

tjoffon A big win for Android interoperability

Yes... that $25 if they manage to get even that before it is blocked I can live with. Loosing my phone, even if they can't do anything with it is a whole other scenario. Now I can't even get home.

tjoffon A big win for Android interoperability

Yes it is. Doesn't break if drop it for one. Much smaller than a phone. Isn't tied to apples ecosystem. etc.

I get that you might want one if you are a tech maximalist with a single focus. But that doesn't mean you should stop carrying your card.

tjoffon A big win for Android interoperability

Because a normal card is superior in most practical cases?

tjoffon Turning a dumb AC unit smart (without losing my security deposit)

I'd never trust that it will hold and detach without residue, but that is probably my ignorance talking...

I own a 3d printer which makes most of these projects look like the perfect fit for a 3d print (even when there are far simpler solutions). So that is what I'd do :)

tjoffon Mag Computer: A Mag History of RAM (1960–2025)

Exactly, I also want to add that 16 GB at that time would probably correspond to 128 GB today.

My 13 year old laptop, that I still use from time to time (mostly because it is the only windows machine I have) has 8 GB of ram (which truly is barely usable today), it is on the slimmer side and my requirement to have at least 8 GB of ram at that time really limited my options (and there was no option to get more than that in a slim form factor). The norm (not even entry level) was 4 GB and there were tons of options with even less than that.

tjoffon Mag Computer: A Mag History of RAM (1960–2025)

Unfortunately the last 15 years computers have deliberately been capped on ram which severely limits the longevity of sold devices.

tjoffon Elevated Errors for Opus 5

Isn't both of those, potentially, just consequences of OAI having more spare compute?

tjoffon Making Xen's dom0 I/O path NUMA aware

While they are fully compliant with the AGPLv3 and can say "our stuff is open source", this satisfies only the strictest sense of the license. It doesn't supporting integration with most distributions' repositories. This ends up looking like a commercial product to most users look for personal to enterprise scale management front ends.

I agree, but XCP-ng is still the most attractive system on the market for home / small business use in my opinion. Xen Orchestra itself isn't needed either, I do most stuff on the cli and code-monkeying arguably reinforces that even more. Patching up something that allows you to VNC a VM for the initial setup/debug doesn't require much investment / knowhow.

tjoffon Elevated Errors for Opus 5

Interesting, but also wholly incomplete without knowing how effective the respective models are and how much people are actually using them.

tjoffon Making Xen's dom0 I/O path NUMA aware

Very far fetched and was almost two decades ago, never seen that sentiment in regards for Xen. Xenserver seems a bit mismanaged though.

The original question was vague, but we are getting a bit all over the place. Hyperscalers and most other uses don't really overlap that much.

tjoffon Making Xen's dom0 I/O path NUMA aware

Why is KVM a thing when we have great and free Xen virtualization?
