Curious to hear what folks here think about Goodhart's law playing out when a company does something like this. https://en.wikipedia.org/wiki/Goodhart%27s_law

These days you don't even get that on most occasions even in a "forgot password" flow. You still have you key in your email address or username again pretty much everywhere.

I was a bit surprised to not find a reference to the singularly most irritating thing about Google's recaptcha - that it treats me - the one trying to authenticate - as a free source of data labels for its ML systems. I guess I&#x2

Correction: exp(i2πm/N) .. which gives you Fourier coefficients at m.

Ref comment https://news.ycombinator.com/item?id=25195046 about this. Further to that, if you replace x with complex variable z^-1, you get what is usually called the z-transform. Set z to a specific complex root of unity e

(sum_i ai x^i)(sum_j bj x^j) when you expand that, the coefficient of x^k is the sum of aibj such that i+j=k which is discrete convolution. Set x=10 and you're dealing with decimal representation of numbers.

Convolution is digit-based multiplication, so why not start with that? 100101 * 23 = 2302323. If you defer the carry over to the end, the digit-based steps we do is convolution. That said, giving lots of examples like those in the artic

I don't recall a single instance of corruption with the Indian railways at the consumer level in nearly 2 decades including an instance when I was fined for not purchasing a platform ticket which would've been an opportunity for t

I believe this is the right explanation .. and I also agree that the experience has been readily getting better .. both the trains themselves and the ticketing system.

I agree this needs more nuance instead of pitching it as a david-vs-goliath. The railways has made steady progress on making it easier to ticket starting with an old mainframe system and transitioning into the web age. Such transitions at t

"simply one equation" that expands to the same set of vector equations which expands to the coordinate-system-specific equations. ∂F=J (barring constants) is a beautiful restatement, but I think it puts the cart before the horse t

Is this about the audio streams? I imagine that if at any time there are a million video streams happening, and zoom wanted to sneak into 1% of them, it would pretty much need 10000 vCPUs of compute to do that? The current tech scales affor

It seems amenable to constraint propagation + search. Assuming no repeating digits to start with, each digit is assigned a position variable on which sequence constraints can be applied, propagated and searched. You might end up with no sol

I'm familiar with COM and I do think the kind of interoperability you get with open multiple dispatch is of a different character altogether. There has not been any theoretical reason why this has to be true yet, but empirically it has

This is the right attitude. In cases, information leak can lead to even loss of life (ex: healthcare) and "we're nice to our employees" cannot be a plan to protect this info when you're working with clients of that kind.

When it comes to our bio-ecosystem, I'm repelled by this kind of a question as, in general, I don't believe we understand ecosystems with complex interacting parts well at all .. and are therefore not well placed to make such swee

I think to some extent at least, having an open-to-extension capability like what Julia offers (open multiple argument dispatch) could help with this. This isn't at loggerheads with the idea of an application, but let's such appli

Erlang certainly seems very close to that description. One principle that gets flouted for convenience is exposing internal "objects" directly via accessorsor other methods. Instead, the idea behind message passing has to be clari
