What? If you have a good model of your system then you can (relatively easily) turn it into an optimization problem and use a LQR to choose gains for you. It’s true, this method still gives you knobs you might have to tune (Q and R), but th

Just because a C programming experience is possibly going to happen far off in the future doesn’t mean that beginners should commit to having a traumatizing ‘70s computing flashback as their first real programming experience.

This seems like it's a great example of survivorship bias: the Romans probably made lots of concrete that didn't survive the elements, but there was some that the Romans did get lucky with. It's also possible that we don&#x

This is not correct, at least in the US. You can keep it even if you didn't order it, regardless of whether or not it was sent in error. https://www.consumer.ftc.gov/articles/0181-unordered-merchan...

They already have Patreon-like features for servers where you can "boost" a server with tokens you get from your Nitro (premium) subscription. These "boosts" allow the whole server to get more stuff.

I disagree with your argument that we shouldn’t care about this as long as it’s legal. There are many things that are legal but still damaging or wrong. In many cases (including this one, IMO) we as a society should be able to know more abo

When people say the US is business friendly, I think they’re really observing that the US is big-business friendly. Convoluted taxes allow big business and the very wealthy to evade them more easily. Convoluted bureaucracy makes it easy to

Perhaps you can learn without a calculator, but these timed statistics tests do not function without one. Do you really expect people to do repetitive operations on even n=10 datasets when they only have an hour? You can’t use Excel (becaus

I think the GP is drawing a distinction between private and personal property. If you outlaw private property (e.g. things owned in absentee by entities, usually to seek rent, like landlording) then you are not outlawing people owning the p

We have excess energy all the time. Many power plants have fixed, unpredictable (e.g. solar/wind), or slow-changing output. When demand is low, these plants often are often producing excess power. An even more egregious example is gas

I think that GP's position is tenable if the tyranny comes slowly. Sure, a country-wide armed insurgency is hard to beat. That's relatively uncontroversial. If most people are comfortable as the water boils around them, however, t

Is C++ -> C interop your only reason for avoiding C++? If it is then you might reconsider C++, because calling C code from C++ is usually as easy as wrapping the #include in an extern "C" block.
