Sounds like you should look into it instead of idly speculating! Also, the funny thing about a divisive feature is that it doesn't matter if it fragments the community if you can use it successfully. There are a lot of loud people in t

This is quite a complicated approach that misses out on most of the basic numerical and geometric methods that will make the problem simpler. I would recommend looking outside of recent SIGGRAPH papers. Brushing up on the basics of Bernstei

One way to think of the sinc function is as the reproducing kernel (the point evaluation functional) for the space of bandlimited functions, thought of as a reproducing kernel Hilbert space. I guess the Shannon/Nyquist theorem just kin

Here's an implementation of a doubly-linked list which is perfectly fine on modern hardware: an array of structs where each struct contains a pointer to its next and previous elements in addition to whatever other data is being stored.

I don't know what it is about this name, but I read it as "My Fiancé". My brain did not register the first "n" and it wasn't until I read your parenthetical remark that I went back and re-read. The name isn&#x2

I guarantee you if you build that bananamobile you will find plenty of uses for it! Don't hold back!

Great blog post, totally agree with it... except, "Cars and Trucks and Things That Go" condescending ? If you think Richard Scarry is trying to keep kids engaged with "the false novelty of a carrot car" (!!!) you do NOT

It isn't either/or. Good programmers know how to use both and know how to choose the appropriate tool for the job.

It's no more or less a good analogy than any other numerical or computational algorithm. They're a fixed precision format. That doesn't mean they're ambiguous. They can be used ambiguously, but it isn't inevitable.

None of this is contradictory. 1. Compiler optimizations can be disabled. If a compiler optimization violates IEEE754 and there is no way to disable it, this is a compiler bug and is understood as such. 2. This is as advertised and follow

The purpose of floating point numbers it to provide a reliable, accurate, and precise implementation of fixed-precision arithmetic that is useful for scientific calculations and which has a large dynamic range, which is also capable of hand

by sfpotter 1y ago
Floating point numbers aren't ambiguous in the least. They behave by perfectly deterministic and reliable rules and follow a careful specification.

Oh man, I love crazy stuff like this on HN. For a community which espouses rationality and careful thought, somehow an article with "C ~ D^2" has floated to the top. No notes.

Why not? At any point in time since then there have been new technologies that don't exist. As a company, you can always make the call to hire people without that specific experience and train them, or you can punt and wait for a 3rd p

On the flip side, back in the 70's Boeing used to do things like hire up people with no immediate experience, teach them C for three months, and then hire them into roles as programmers. I'm not sure you can decide what's &qu

C++20 concepts are a step in the right direction, but: - D had this feature long before C++ did. - It isn't the same thing as "static if". Without "static if", conditionally compiling variables into classes is much

by sfpotter 1y ago
"if constexpr" introduces a new scope, while "static if" does not. A major divergence, enough to make the features very, very different in terms of what they can actually be used for.

Interesting point about BB(n)... Is it known that BB(n) is finite for every n?

This is truly a wonderful thing. I hope you all appreciate how lucky this is and protect the institutions enabling this.

In the US, I think it's a combination of broad-based anti-intellectualism and scorn for those who do care or service work. "Those who can't do, teach" is a phrase that's ingrained in most young people. I think many

Generally speaking, when I hear people say this, it's a huge red flag. Really, any time anyone puts forth any kind of broad proclamation about how software development should be done, my hackles go up. Either they don't know w

In Seattle, 5% is meager considering what tech workers here make. If you work as a teacher in the city of Seattle, you're likely looking at ~$100K/year, after at least a few years of experience, and assuming you have a masters deg
