Sounds similar to QuantumScapes battery. Anyone know what’s different? There was just a very interesting interview with Munroe: https://youtu.be/OKFiQIMyF-A Seems like they and their customers believe the battery is ready f

If I understood it correctly, they’re not talking about a chip literally running at 50Mhz. They’re talking about polling a sensor in a loop running on a 50Mhz timer. The processor doing that is certainly running at a much higher clock frequ

Good move. The problems related to mining is my main reason for not wanting to buy any jewelry with gems. Maybe I'd consider buying something from a brand that avoids all mined diamonds.

I’ve never lost my car keys, but I plan to get airtags for them because replacing key fobs can be insanely expensive now a days. I wish AirPods acted as airtags. Those are the only other things I’m kind of worried about losing. Mostly becau

by audunw 6y ago
I’m assuming AirTags just send out Bluetooth advertising packets. Your phone is continuously listening for those anyway to detect devices you own, like your watch and headphone. So that part is “free”. The power required to process the pack

The problem with blaming the response, is that a strong response with very strict lockdowns is sometimes a result of a weak early response. That is, if you hesitate with doing lockdowns, you'll eventually be forced to do a much more se

I think another common fallacy is to assume that humans have more general intelligence than we actually do. This is manifest in three ways: 1. Assuming that we can build an AI than can do what a human does, without being embedded in the phy

This is just my personal belief: but I really don't think an AI advanced enough to actually do self-driving will have trouble getting all the information it needs from cameras. It seems to me that accurately determining signs, construc

They are perceived to be very far ahead on vehicle assist and self-driving. I can't say if they actually are technologically speaking, but I think the perception they have will give them a significant benefit for years ahead. A part of

Battery does not just degrade with power cycles. It also degrades with time. Not sure about the numbers for LFP, but it's something you need to take into account. For some areas time may be a more important factor than cycles. If it do

You should not use Thunderf00t as an authority on this. He has no clue what he's talking about. That seems to be a problem in general, he doesn't actually do much research on the topics he talks about. So unless he already has som

It's a common misconception that energy storage needs to handle all the power needs of an area for a significant time. The most immediate need for energy storage is frequency regulation, and short hours-long dips in power output. If we

I really wish Thread mesh networking would become standard on new Wi-Fi routers. Google Nest has hardware support for it, but not sure if it's enabled yet. I think Thread is a much better fit for IP connectivity for IoT devices. Nordic

Nordics tools and documentation are generally considered relatively high quality. Not perfect, but the competition is usually worse. That's one of the main reasons they are dominating the Bluetooth LE peripheral market.

I think any analysis of the dangers of AI need to consider the principles of evolution. Human intelligence is a product of humans evolving in a natural world, where individuals were selected for their ability to compete for resources in tha

What? Bluetooth is 2.4Ghz. I guess it's just a proprietary 2.4Ghz radio protocol (Nordic Semiconductor low-latency proprietary I guess) vs Bluetooth (on 2.4Ghz).

It would most likely not be a very short war if the people of Taiwan are serious about their independence. What's an embargo really going to do? Piss off the whole world and create a shitload of sanctions on China. Taiwan is not a city

It might be worth looking at West, used by Zephyr (embedded RTOS): https://github.com/zephyrproject-rtos/west Not sure how mature it is or if any other projects use it. But seems to be working well for Zephyr.

I really think China is making a huge mistake actually. See how TSMC (Taiwan) and Samsung are free to buy ASMLs EUV machines, while China is blocked. Part of that is due to their rampant IP theft. Why sell machines to China if they're

Why do people still claim Bitcoin is a store of value? It has none of the properties of a good store of value IMO. - Boom/bust cycles means you’re at high risk of not being able to withdraw without losing most of your value - There’s n

No, the main reason nuclear has a hard time these days is that it's expensive. Governments simply don't have the willpower for a decade long trillion dollar push for nuclear when the pay-off is far longer than 1-2 election cycles.
