Interesting idea, I suspect it isn't possible with the existing connector. You either need to increase the voltage or the current. The new 240W spec is 5A and 50V. Assuming 5A is t…

Interesting point, but of course it’s not possible to create a platform with an average win rate of 80%.

Grounding isn't really about dispersing energy over an area, it's about creating a situation where faults can be detected and circuits automatically opened to prevent shocks or fir…

Very often with contract law there is mostly no such thing as 'knowing a claim is not legally valid'. A lot of contract law is established by precedent, meaning in those cases nobo…

I suspect (IANAL) that in a sense, it already is, in that anybody testing this in court would deny the existence of any form of contract acceptance, and that would be the end of it…

And that heat ends up at the worst possible place, on the junction itself, meaning the device has to also work to remove it.

For an article about a specific scientific concept (the proportional land use for different types of generator), it’s surprising they actually got that concept wrong in all their e…

They look identical to me too, but I know that I can perceive RGB hues.

This has been true of OSX, especially since around 10.15. The performance degradation of the upgrade to 10.15 from 10.14 was so immediate and severe that I reverted it.

It only had itself to blame

And the atrocious disregard for performance over the last few years. My 2014 OSX 10.14 home Mac Mini is so much faster and more responsive than my 2021 OSX 12.4 work Mac mini (with…

For some types of power supply, not having a proper ground can dangerous for reasons many people don’t realise. It’s not just about fault currents ‘flowing to ground’. Should just …

Interesting observation, yes, power might restrict the deployment as much as running e.g. cat5 to a fixed camera install. A decent PTZ can easily see over that kind of range - some…

In response to the comments of the form "just install PTZ cameras", I have done an installation like this for a modest-sized site, and it is extremely difficult and time consuming …

Agreed. As an existence proof, the optimising compiler for language X could realise that a for() loop that uses 95% of the actual runtime CPU has no side effects and can be removed…

1440*2 different pre-rendered videos I assume.

I think the key conceptual thing that's difficult to grasp is the propellor's interaction with the wind. Forgetting the speed of the car vs the wind for a moment, the propellor is …

What do they feel like for you? I’ve had a CO2 sensor in my office for a long time, and don’t think I can tell the difference between 500 and 1500ppm.

I personally don’t understand the claimed need for such high bandwidth for video calling and general business use. My work laptop has forced software updates, so at the start of lo…

Another scummy website that hijacks the back button. I wish there were a way to block domains from the results I see on HN.

Both PCs and fan heaters are 100% efficient at producing heat.

In my view the audiophile £500+ Ethernet cables are more than borderline fraud.
