Did a high school project on the jam and replay attack mentioned here: https://github.com/trishmapow/rf-jam-replay. Low cost SDRs have been a real game changer in letting the average Joe get started in this space. Good to see that more unis have courses with this type of hands on experimentation.
The causality of this condition is not the same. Prion issues cause both sleeplessness and death, which is not the same thing as sleep deprivation leading to death. Thanks for the link though, this is interesting.
In the modern digital era, that has actually changed quite a bit. Now cameras are really sensitive – the equivalent of what used to be 2500 to 4000 ISO is now really common – so instead of adding light, often you have to flag off light in areas you want dark.
So instead of many bright lights you just have duvetyne and flags everywhere, which many DoPs have complained is harder to work with.
A stop is double the amount of light. Useful for equivalence across different ways of changing exposure. So I halve my shutter speed I’ve lost a stop. But I increase my aperture from 4 to 2.8 I’ve gained that stop back. Or I double the sensitivity of my film or sensor (eg. iso 400 to 800).
So yes, in terms of data if using linear gamma exactly equivalent to bits. This is why log gamma curves are used to store for eg 16 stops of light info in 12 bit format
Imagine light represented as a floating point number of the type a * 2 ^ b
Stops describes the range of the exponent b.
With a typical cinema camera, max_b > min_b + 14
You can use tricks like gradient ND filters to increase the perceived range within of a frame or variable NDs to slowly adjust over time (like our eyes do)
Samsung has directors view which records front and back simultaneously. Would be surprised if flagship devices can't do this due to hardware limitations.
Yes, but how do I know that there isn't a Cloudflare edge node somewhere in my storage cabinet, announcing anycast routes for 1.0.0.1 and 1.1.1.1 to reduce latency?
Article clearly says that "In Germany, drivers can legally use their cellphones while Drive Pilot is engaged, a first for semi-autonomous systems". However, you can't go to sleep.
If your car is yelling at you to grab the wheel, I'm sure you can take two seconds to put your phone in your pocket. With one hand even, so the other can go to your wheel, and your feet are still nice and snug on the pedals, ready to brake should you need to.
I think the crucial thing here is, in this case if you don't do any of that, Mercedes will still take responsibility for a crash until the ten seconds is up.
Therefore they need to be very confident in that ten second rule, and naturally we look for cases where it might not work out well.
Hmm I know it's not the same but I see a lot of people fall asleep on public transit only to be jolted awake, look around confused for a few seconds and then bolt for the doors because they are realizing they're about to miss their stop. I think it's great to say "you can't go to sleep" but I have a feeling people will fall asleep anyways, especially commuting to and from work. Based on the disoriented, panicked, suddenly awake people I see on public transit, I think the 10 second warning could scare somebody awake, have them panic and cause an accident.
