Remember when I posted about PyCon US and Art in the same toot? Well, some friends and I are pretty excited about it.

And guess what, we're looking for folks to join us on Friday, May 15 to create art, showcase art, and even discuss what art even means in this age of "AI".

https://us.pycon.org/2026/events/open-spaces/#openspace-40

We want to showcase the creativity of the Python community, and we'd love to see your art. Do you have something you plan to bring? Or an idea for an art project you want to lead?

(We're also looking for a few volunteers to help us run the open space(s). Let us know if you want to volunteer to make this celebration of creativity happen.)

You can message me here, on DM, or send an email to pycon+art@pythonbynight.com

forgive me, for I have sinned:

```python
class Derived(Base):
@classmethod
def load(cls, pth):
instance = Base.load(pth)
# engage body horror
instance.__class__ = cls
return instance

def sugared_func(self):
print("a miracle occurs")
```

On Python, `loky.cpu_count()` will take cgroups settings, common in Docker and Kubernetes, into account when calculating number of available cores.

Are there any other Python APIs that support cgroups options? Standard library doesn't.

(On Rust you can use `num_cpus` crate, on R there's parallely::availableCores()).

#Python #cryptography library (yes, the one that criticizes everything and everyone) is now vibecoded. Our future is truly bright!

Noticed because apparently "Claude" wrote a test that OOM-ed my system. But hey, #RustLang protects against memory errors, so it's fine to vibecode your security critical components.

I'm seeing some weird behavior with FastAPI and async.

I have a function:
```
async def foo(r=[]):
if r: return r[0]
r.append(someobj())
return r[0]
```

Now I have that declared on a route via the usual:
```
@router.get('/somepage')
async def get_somepage(foo : Annotated[someobj, Depends(foo)]):
xxx
```

But in the foo function, I print the id of the r list, and each time somepage is fetched, the list is different.

I did finally just move r into the module name space, and that fixed things. But it's pretty clear that FastAPI is doing something wonky with function calls.

I’m happy to announce the release 0.17 of the poezio terminal #XMPP client!

This features adds support for XEP-0444: Message reactions.

You can read more about it on my blog: https://blog.mathieui.net/poezio-0-17.html

Fun fact: poezio was one of the very first client with support for message reactions, during the XMPP sprint where they were initially fleshed out, but the PoC branch got lost in a forge move 🤐

Every Python dev has faced APIs that use camelCase or kebab-case while your codebase follows snake_case.

The typical approach creates technical debt: either break Python naming conventions or write complex mapping logic that clutters your codebase.

Pydantic's Field alias feature elegantly solves this: define external field names through aliases while keeping internal code perfectly Pythonic.

Integration compatibility and clean code that's maintainable. 💚
