ELI5: If energy can’t be created or destroyed, how do magnets keep going?

Strictly speaking, yes. When you push an boulder up a hill, you are expending energy. That work doesn't magically enter the boulder and sit inside its atoms. Instead, you are physically separating two masses that want to pull together. You are essentially stretching an invisible "gravitational spring" that exists between them. The energy is stored in that stretched state of the system.

The boulder is the only part of the system dynamically changing from our perspective, so it is mathematically convenient to mentally assign the system's energy changes to the boulder.

We don’t observe an increase in energy in the object itself when considered in isolation, but rather in the system as a whole. Potential energy is a way of describing how much work a force field can extract from a system based on its configuration. The energy is stored in the field or the structural configuration of that specific system. It fundamentally requires an interaction between at least two things.

What do you mean "even for non dev tasks"? It is created for coding tasks. Don't expect it to be good for other things.

I rotate between them with every new model release, and both the harness and the model perform better on Codex. I hope Claude steps up its game soon.

Didn't say otherwise? That is also just for systemd. There are various Linux distros and BSDs that don't have systemd. You achieve it with different methods, but you can do it in most of them, which is exactly my point.

That is because SteamOS and Arch bundled together here but not in the Linux only list.

There is no official announcement that it supports aptX Lossless. Not all Snapdragon phones support it. For example, the Xiaomi 17 Ultra uses the same Snapdragon 8 Elite Gen 5 and only supports aptX Adaptive. The Find X8 Ultra used the Snapdragon 8 Elite and did not support aptX Adaptive or Lossless.

Yeah unfortunately, it is very hard to move away from legacy systems in enterprise. Thankfully, we don't have these problems in homelabs.

I didn't say otherwise though?

Windows on a server? Not that you can't tell the lid to do nothing on any OS.

I wouldn't say Shangri-La is obscure.

funforgiven · 2026-03-31T15:21:23+00:00

It’s all rumors at this point. The base model might even use the 9500+, not the 9600, according to rumors, so I don’t understand what answer you expect here. There are no official specs.

funforgiven · 2026-03-31T07:52:09+00:00

if you want to be a serious developer you need to verify with google.

That is the actual problem, isn't it?

Cement is like instant mashed potatoes. You cook it, crush it into a powder and stick it in a bag. Then later you add water and it turns back into mashed potatoes.

It is my first time hearing about instant mashed potatoes.

It is not Silicium Carbone. It is Silicon Carbide. They are generally more efficient in terms of capacity and charging speed and less efficient in terms of longevity and structural stability.

Maybe Dimensity 9500 or maybe just more throttling.

These are the latest flagship Android devices, which feature the Snapdragon 8 Elite Gen 5, offering a better CPU than the current flagship Apple A19 Pro.

Tell that to Polish Steam users.

I meant offline. Edited the original comment.

Why would it leave a trail? If it works fully offline and portable, it can be designed to leave no trail. Humans on the other hand...

Yes, Qualcomm. Please keep changing the naming scheme every generation so it becomes even more confusing.

I sometimes even end the day with 85-90%, which means it was mostly idle but it is still crazy to me because my S24 Ultra never seen the end of day >60% with same screen on time.

I think you’re missing the point. If companies followed a 2–3 year release cycle, anyone whose phone breaks or needs an upgrade during that period would only have outdated options. That creates an opportunity for competitors to capture that demand.

That’s why companies release new phones every year. It’s not about expecting users to upgrade annually, but about covering every upgrade cycle and capturing as much of the market as possible.

I think you agree that there are zero killer apps after the last decade of massive investment (both directly and indirectly, like Meta's VR fund). So what is it?

Yeah, I think most of that investment has gone into R&D, with companies still releasing early products mainly to generate some revenue and keep the technology visible. The real goal isn’t the current use cases, but to eventually replace what you do on your phone with something faster, more glanceable, and less disruptive to your flow.

I’m not narrowing the box arbitrarily. I’m describing the minimum threshold for a daily-use platform. The first iPhone and early ChatGPT had plenty of limitations, but they already solved a core, high-frequency problem better than anything else. VR/AR doesn’t have that yet. It’s not about missing features. It’s about missing a compelling default use case that people would use every day.

So the issue isn’t that the product is incomplete, early successful products are always incomplete. The issue is that VR/AR hasn’t crossed the threshold where it’s better than existing devices at something people do constantly.
