Because, what, Python doesn’t have any language details related to method lookup that might require a sentence or two of technical explanation? __getattr__, __getattribute__, __get__, base classes, metaclasses, __mro__, __mro_entries__, __

The finite difference method of that video is only useful for finding polynomial sequences. Of course, any finite sequence can be extended to some polynomial, but in many cases (such as this one) that’s not the result you’re looking for.

Perhaps the most important difference is that expressions re-evaluate automatically on changes. You don’t have to go manually rerun all the dependent expressions, or wait for the kernel to restart, or worry that some of the results you’re

Yes, as of last month. I’m not sure if it works with YAPF; it’s designed to work with Black and doesn’t currently have many of isort’s configuration options. Worth a try!

You should not pin the public requirements that get uploaded with a library (listed in setup.py, setup.cfg, or pyproject.toml), since that will restrict your downstream users, leading to version conflicts and persistent security vulnerabili

If you aren’t happy with Flake8, Pylint, and isort (or maybe if you are!), I recommend checking out Ruff: https://github.com/charliermarsh/ruff It’s literally 100 times faster, with comparable coverage to Flake8 plus d

SHA-256 is vulnerable to a length extension attack. This is well-known to cryptographers; it doesn’t matter for some applications and can be worked around in others. But it still catches some developers unaware. https://en.wiki

The article’s objection to “parenthesized nonsense” is about the nonsense, not the parentheses. 3(%edi,%ebx,8) is hiding a multiplication, two additions, and a memory access, in an order that you wouldn’t guess from the syntax.

Type guards in TypeScript are not sound: the language makes no effort to prevent you from defining an incorrect type guard that, when used, narrows your variables to incorrect types. Your mistake won’t be caught at compile or at runtime (u

I think part of the parent’s complaint is that, although 23976/1000 fps is much more accurate than 24 fps, it’s still very slightly slower than the correct value 24000/1001 fps, by about 2.1 frames per day.

The sense in which the Lisp code (list 'lambda (list 'x) x) evaluates to the data representation of (lambda (x) x) is exactly the same as the sense in which the lambda calculus code λa. λb. λc. c (λx. λa. λb. λc. a x) evaluates to

Yes, I was clear above that I know ' means quote. My experiment is to compare Lisp to a restriction of Lisp where quote only works on symbols. This restriction doesn’t make it any harder to write a self-interpreter. > If we have

The situation with Lisp is exactly the same. To run a Lisp self-interpreter, we don’t pass it a Lisp function: (interpret (lambda (x) x)) but rather an encoded version of that Lisp function’s code: (interpret (cons 'lam

by anderskaseorg 4y ago
There is. Using the Mogensen–Scott encoding, a self-interpreter can be written in lambda calculus as (λf.ff)(λf.λt.t(λx.x)(λm.λn.ffm(ffn))(λm.λv.ff(mv))), which is a direct translation of the equivalent Haskell code data Term t = Var
