They're based on the idea that if you're made to tell a lie, your body will react in some way (sweating, faster heartbeat etc) compared to a baseline measurement. There is a whole field of psychology around lying and additionally

Could you not also train a classifier that correlates question content with mod decision? Questions like "what is the best X? " that are obviously subjective , for example. Maybe even some kind of crazy generative model that lear

You can argue that either way. Seeing 'this' unambiguously implies instance variable. Otherwise you have to spot the underscore and be aware of the conventions in the codebase. A good IDE should highlight class variables vs loca

Is there a reason for not using 'this'? I assume the risk is that you might have a scope where both this->foo and foo are valid and it's unclear which is which. You have no ambiguitiy with this->foo_, and foo (and if yo

Complexity is proportional to the size of the view distance (linearly? Or square if you do a field of view). The map size doesn't matter, assuming array lookup is instant.

The Pixel 2+ does have a coprocessor for compute workloads (the Visual Core). However users here have reported this working on a Pixel 1, which doesn't have that chip. The Verge says it may reach other devices later. It sounds like it&

I've found it really useful on embedded systems (e.g. Raspberry Pi). It takes a long time to install anything complicated, and you occasionally need to make kludges. Having a Dockerfile means (a) I can remember what I did to make every

For airspace it doesn't matter too much. Allowable Mode-C accuracy is something more than 100 feet (I think) to allow for poor sensors, and controllers simply add a buffer.

GPS gives you a 3D fix (lat/lon/height). A common use case in aviation, particularly drones, is avoiding controlled airspace. The height of controlled airspace varies with location - for example a rural area might be 7500ft while

Tangential question, is there a canonical way to build cross-platform docker images without using docker hub? For example, armhf on an x86. I've seen some stuff from Balena, but nothing that looks particularly straight forward. Unless
