We have "growth hackers" but no "stability hackers." "Disruptors" but no "preservers." Our entire vocabulary is oriented toward the new. We have no language for the equally difficult work of keeping existing things from falling apart.

@scottjenson @tris that, plus I think @tbernard could be a direct contact that is also in mastodon
@xgranade @emmatyping @whitequark @SnoopJ @ancoghlan @mcc btw in the interests of avoiding at least *unnecessary* annoyances, if you're doing PEP 695 style type parameters, the TypeVar imports and instantiations are fully unnecessary
@glyph @xgranade @emmatyping @SnoopJ @ancoghlan @mcc oh TIL! this will be rather useful.
@whitequark @emmatyping @SnoopJ @ancoghlan @mcc no accounting for taste I suppose!

Merry Christmas to everybody, except that dude who works for Elastic, who decided to drop an unauthenticated exploit for MongoDB on Christmas Day, that leaks memory and automates harvesting secrets (e.g. database passwords)
CVE-2025-14847 aka MongoBleed
Exp: https://github.com/joe-desimone/mongobleed/blob/main/mongobleed.py
This one is incredibly widely internet facing and will very likely see mass exploitation and impactful incidents
Impacts every MongoDB version going back a decade.
Shodan dork: product:"MongoDB"
@GossiTheDog https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-14847 is a 404. I guess they assign a different CVE if one of their products based on MongoDB is affected?

It occurs to me that a good predictor of whether someone will embrace #Zettelkasten¹ would be if they like city-building games (SimCity, The Wandering Village²).

@emmatyping @whitequark @glyph @SnoopJ @ancoghlan @mcc More generally, though, that's a case where Callable fails to be covariant on its return type — if a program passes for a given return type, narrowing that return type should always pass as well.
All that is what tells me that mypy acts in practice more as a linter than as a type checker? Perhaps I'm misunderstanding, then?

@lzg good luck!

@mcc seria uma boa ideia.

```
from typing import TypeVar, Callable, Optional
T = TypeVar("T")
U = TypeVar("U")
def g[T, U](fn: Callable[[T | U], U], x: T) -> U:
return fn(fn(x))
def f(_: Optional[int]) -> None:
pass
x = f(12) # Fails
f(f(12)) # Fails
g(f, 12) # Works
```
@emmatyping @whitequark @glyph @SnoopJ @ancoghlan @mcc As noted, that's an MWE for something I did hit in practice. While I wouldn't write that exact snippet in practice, it came up in the context of composing functions. A slightly less minimal example shows a more practical version:
