#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.

Web app db design: if you have optional string fields, do you make the column nullable, or not nullable with a default empty string. Consider HTML form data (empty field is sent as empty string, not omitted), and rendering (rendering empty for None has to be remembered everywhere). I've never seen any consensus.

RE: https://mastodon.social/@andrewnez/116478133377243019

Workflow security continues to be a common cause of compromises of open source projects.

If you're using GitHub Actions and don't want this to happen to your project: use Zizmor and treat the findings seriously, especially insecure triggers and user-controllable template injections.

At this point having zizmor scans of every python package is turning out to be quite the crystal ball: https://www.stepsecurity.io/blog/elementary-data-compromised-on-pypi-and-ghcr-forged-release-pushed-via-github-actions-script-injection

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.

Learn how to program an 8-bit computer. It’s the biggest f*ck you to AI bros and their slop; you will learn more about computers than you ever will from gluing frameworks together, and lastly it will come with no responsibility whatsoever.

Stop contributing #JavaScript and #Python knowledge to the slop vendors. Microsoft, Google, Apple et al can’t make money off of 6502 or Z80 code. More Commodore 64 games existing is not going to contribute to murder drones shooting kids.

Question for the Python people: How do you handle type checking in CI? Do you just install all the dependencies every time the pipeline runs? Do you have some logic to install missing type stubs (or the real dependencies, if there are no stubs)? Something else entirely?

Old habits die hard. Needed to choose randomly one of 18 items printed out on a piece of paper, with some exclusions. Went to #Python:

random.choice(list(set(range(1, 19)) - {5, 11}))

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. 💚

more specifically, this PR exposes a curious side effect of the Unicode 15.0 → Unicode 15.1 upgrade when it comes to #Python identifiers: ZWJ is now allowed as a 'continue' character (i.e. you can use it in an identifier as long as it's not the first codepoint)

```
$ python3.12 -c 'print(str.isidentifier("A_\u200d_B"))'
False
$ python3.13 -c 'print(str.isidentifier("A_\u200d_B"))'
True
$ python3.13 -c 'print(str.isidentifier("A_\u200d"))' # unfortunately, a trailing ZWJ is legal too
