my homie dhall posted:

what is an array but a set with the added complexity of ordering?

well, at least in javascript a set can only have a single instance of a thing:

JavaScript code:


const buttsArray = ['butts', 'butts', 'butts'];
// Array(3) [ "butts", "butts", "butts" ]
const buttsSet = new Set(buttsArray)
// Set[ "butts" ]

i say that because i'm sure there is some definition of a set that involves greek letters and makes my eyes slide right off the screen

just found out that the hard way that if a python function has a parameter with default value that's an object, it's persistent between calls, so you get things like this happening:

code:

>>> def test_def(x = []):
...     x.append(1)
...     return x
... 
>>> test_def()
[1]
>>> test_def()
[1, 1]
>>> test_def()
[1, 1, 1]
>>> test_def()
[1, 1, 1, 1]

Had me spinning for a bit.

Yep, python evaluates default params at function definition, so you�re better off using None and initialising the default value in the body instead

yeah only reason i know about that one is because it's a classic interview question.

it makes sense from a certain perspective but it is certainly counter-intuitive.

I'm just really glad it is rare enough that none uses it that way on purpose

the client�s authentication could be a cookie, or an Authorization header token, or a client certificate for TLS, or simply being on an internal network for some cases

well don�t auto send auth headers either of course. I don�t know about client certs, but local network is a good example and it�s funny IME that sites authenticated that way are likely to have cors disabled!
