Not OP, but I'd be more interested in making a tiny ball round enough to roll across a surface and fall into a hole (not the "absence of an electron" meaning of that word). And I'd want it achieved through gravitational forces rather than electromagnetic. I feel like that makes the problem harder and largely makes it a materials science question. Someone in MEMS research probably has a good idea of how to approach this.

With those parameters, the system would probably need to operate in a high vacuum with as little interaction from electromagnetic forces as possible. All materials used should probably have a low permittivity to reduce the amount of static charge buildup from friction. Intuitively, I feel like it makes sense to use the same material for everything. But it might not be that simple. Maybe the material used to make the smallest round ball isn't well suited to making the smoothest surface for a short putting green?

I dunno, I'm just a guy who took a few classes on semiconductor design in undergrad spit balling.

I've always had an issue with calling any of this AI. The branding is part of the problem. These people probably don't realize that they're talking to a fancy word predictor tuned to stroke their egos for engagement.

If it comes with the bubbles screensaver, I'm in

Dude's not a "public figure" in my world, but he certainly seems to need help. He sounds like an AI hallucination incarnate.

Thanks for this. Another important bit:
5,000mAh × 3.88V ÷ 1,000 ≈ 19.4Wh

Didn't know there was an Android version!

I've been using OnlyOffice on Linux for a while. It's what LibreOffice could be if Libre's UI wasn't a potato. But does anyone know if fears about its ties to Russia are legitimate?

When I looked into it, I didn't find anything to worry about. Just a lot of fear mongering, because Russia=bad.

Are these so-called experts supposed to have me believe that gambling apps designed to get people addicted to their gambling app might be a gateway to gambling addiction?

I've heard rumblings about the beta amyloid hypothesis being weak or incomplete for a while. Does anyone better versed in the research know what alternative hypotheses have shown promise?

I don't think it's realistic, but what they mean is that the community can in theory get together and decide to fork the code, collectively deciding that BlackRock's Bitcoin addresses are no longer part of their Bitcoin network. The BlackRock Bitcoin would be incompatible with the forked code.

The result of a fork like that is two coins: BlackRock Bitcoin and Everyone Else Bitcoin. Every holder of the original Bitcoin gets an equal amount of both. It's a popularity contest between the two resulting Bitcoins to determine the price of each.

In 2017, Bitcoin was struggling to scale. It had absurd transaction fees due to demand (just like Ethereum a few years later), and the community couldn't come to a consensus on how to upgrade it. 10% of the community forked the code to upgrade it by increasing block size, while everyone else opted for an L2 scaling solution. The result for holders was that they ended up with both Bitcoin and Bitcoin Cash in their wallets. Weirdly, the combined market value ended up being higher than value of the Bitcoin before the fork. I sold my Bitcoin Cash immediately and pocketed the money, expecting the price to go to zero. It did not.

 

It's amazing how far open source LLMs have come.

Qwen3-32b recreated the Windows95 Starfield screensaver as a web app with the bonus feature to enable "warp drive" on click. This was generated with reasoning disabled (/no_think) using a 4-bit quant running locally on a 4090.

Here's the result: https://codepen.io/mekelef486/pen/xbbWGpX

System Prompt:

You are a helpful expert and aid. Communicate clearly and succinctly. Avoid emojis.

User Prompt:

Create a simple web app that uses javascript to visualize a simple starfield, where the user is racing forward through the stars from a first person point of view like in the old Microsoft screensaver. Stars must be uniformly distributed. Clicking inside the window enables "warp speed" mode, where the visualization speeds up and star trails are added. The app must be fully contained in a single HTML file. /no_think

 

Is there any Android ROM that supports Wi-Fi audio streaming natively without root?

AirMusic is an app I've used for a few years to achieve this, and it supports a large number of protocols, including:

  • DLNA / UPnP
  • AirPlay
  • Sonos
  • FireTV
  • and more

However, without root, AirMusic relies on capturing audio from the screen recorder app and relaying it. It's a clever workaround, but I find it frustrating that stock Android doesn't simply support Wi-Fi audio at a system level. It shouldn't be this hard.

I'm currently running GrapheneOS. Unfortunately, the native screen recording app in Graphene seems to block AirMusic's ability to capture audio entirely, so I've lost the ability to stream audio.

Does anyone here know of a better solution?

Frankly, this seems like a feature that should've been native to stock Android 15+ years ago.
