By precisely timing them you can measure/check various facts like distance, diameter and so on. In fact, if you time them precisely from different locations on earth you can determine the shape of the occulting body (e.g. an asteroid o

I've noticed various TV's/TV networks dropping pause/rewind etc and even making the off switch hard to access; it feels as if they want more control for them (and less for the consumer). Especially given the financial cl

Yes, though sharing BLE with other protocols is challenging (even with first-class citizens like ANT+ there are various caveats). The proprietary protocols are Shockburst/Gazelle [0] which are based of the ancient nrf24 setup. Having s

The older Nordic SDK wasn't too bad (once you get over the learning curve). Trying to start a project from scratch is challenging though, so much easier to pick the closest example, get that going and modify from there. However, they&#

£1200 UKP, so a little less. Targetted at having 48GB (2x24Gb) VRAM for running the larger models; having said that, a single 12Gb RTX3060 in another box seems pretty close in local testing (with smaller models).

I'm not aware of any particular guides, the setup here was straightforward - an old motherboard with two PCIe X16 slots (Asus P8Z77V or P8Z77WS), a big enough power supply (Seasonic 850W) and the stock linux Nividia drivers. The RTX 30

Depends on the model, if it doesn't fit into VRAM performance will suffer. Response here is immediate (at ~15 tokens/sec) on a pair of ebay RTX 3090s in an ancient i3770 box. If your model does fit into VRAM, if its getting ejecte

Is this true? I don't have access to the article, but the Boeing crashes and other general loss of control/CFIT must account for a large percentage. Only stats I could find with a quick search are from Airbus who say LOC is the le

A close approximation should arguably include collapses/slides, which happen spontaneously because the pile organises itself to a critical angle; then an incredibly small event can trigger a large slide of salt/sand/whatever

Digikey has a useful article as well. Note how in Figure 5 the PD is reverse-biased to reduce the capacitance without any extra components. https://www.digikey.co.uk/en/articles/how-to-use-photodiodes...

It does seem to, and can anyone credibly say they aren't out of their depth in these waters? (the sandpile thing is not original, it dates back many years). Taking the idea that the "universe is a simulation" [0], what sort o

Maybe it's not that hard to simulate, but let's start with looking at just two of the sand grains that happen to hit each other? They collide, how they rebound is all angles, internal structure, Young's modulus, they have ele

Somehow the universe knows how to organise the sand in an egg timer to form an orderly pile. Simulating that with a classical computer seems impossible - yet the universe "computes" the correct result in real time. It feels like t

For any of these advancements, it depends how they are used. Some people will use them for good, some for profit, some for their own personal advancement. Let's just hope there are enough people out there using these things wisely that

Yes, depends of course on distance, aerial layout and on the decoding technique. Anything over a few hundred miles needs amplification/attention to aerial resonance etc, simply mixing (multiplying) the received signal wth a sine wave

by zh3 2y ago
It's super-easy for very short range, super-difficult for long range. Reason is the wavelength is so long (speed of length/60KHz = 5Kms) that you need a massive aerial for lange range, however for short range you can feed the MW o

If you're into receiving low frequency time signals, you can receive them directly with nothing more than a piece of wire connected to the mic input of a modern sound card (via a capacitor). Sample at 192kHz and downsample in software
