New #python rant. I was using os.system() to run system commands, but this time I wanted to save the output of the command. The answer* is to use either a completely different function or a completely different package.

No single learning in python seems to be transferable. I need to learn some other completely new way of doing everything every time I want to move even a bit from what I'm doing.

People in the #Python ecosystem, has there ever been a developer survey that gathered data about the *usage* of static analysis tools in the Python community? Frustratingly the JetBrains developer survey didn't seem to contain this question.

So after 1 - 2 weeks doing a lot of #perl i don't get why people say write once language? Its not more ugly than lets say #python or #php or even #js. It's diffrent but in no means ugly or harder than other languages. What do i miss? Yeah i get people obsest with writing the smallest code can write pretty awefull onliners but on the other side its like an hiku or a small poem and by no means you should use that in production or in big applications. You dont use a poem to write a book right?

I know "AI" is a polarizing topic around here, but I wanted to share a small side-project I've been tinkering with to scratch a personal itch: MastoSum.

It’s a lightweight web app that listens to public streams, filters for the hashtags I actually care about, and uses an LLM to generate a daily digest of the last 24 hours. Basically, a personalized news feed to help cut through the noise.

It works reasonably well for what I need. Here’s an example of today's run: https://mastosum.linuxserver.pro/s/6q1ZdTOuHBfKyQ3aVU3dOw

It's IPv6-only. Not reachable via IPv4.

Diffify provides you with a comparison between different versions of R packages stored on CRAN and #Python packages stored on #pypi

Say you were using a particular version of a package in a project and now a new version is available. With diffify you are easily able to check what has been changed in the new release. In particular, diffify will provide you with information from the NEWS file as well as changes in the dependencies, namespace and functions of the package

If you are interested in working
- in a science-adjacent nonprofit
- in #python
- doing web backend and data engineering stuff
- *not using generative AI*
- remote work friendly

Please drop me a line! Your application won't skip the queue but I can give you a boost.

That One Draft Post (you know the one) that I've been working on for [unintelligible] months now had me wondering if I even remember how to _finish_ something, so, this was a brief interlude where I checked to see if I could in fact still do that. And also I wanted to write a little bit about #Python programming (a thing I actually like) and not just more about AI

TIL: Don't use #Alpine as base image for containerised #Python applications.

(Because Python combines the worst properties of JavaScript and C when it comes to dependency management, and… well.)

There are a few things in this documentation that are technically documented just fine elsewhere, and that a high-level expert in #Python #SQL integration would be able to tell you about, but many, many product engineers would not realize that they need to look for in the first place.

"Wait… SQLAlchemy Core Support?", I hear you ask. Yes, #DBXS supports #SQLAlchemy Core, and has done so for quite some time. This was previously undocumented so I can certainly forgive you for not knowing.

So the *real* story of this release is not so much any big code changes, but rather updated dependency testing as well as *comprehensive documentation* for the SQLAlchemy feature. This may teach you a few things you didn't know about #Python database support. https://dbxs.readthedocs.io/en/latest/howto.html#sqlalchemy-core-support

“Someone I didn’t know created something I didn’t know I needed next” is the best thing about the #Python and #PyConUS community.

#python is doing my head in. What the fuck is going on here.

```
↳ which cdo

A couple go to Python debugging aids of mine, first is breaking into the debugger.

import pdb; pdb.set_trace()

The second is:
```
def printtb(fun):
import functools
@functools.wraps(fun)
def wrapper(*a, **kwa):
try:
return fun(*a, *kwa)
except:
import traceback; traceback.print_exc()
raise

return wrapper
```

Then any functions that is throwing an exception that I can't easily wrap elsewhere (or have no clue where it's being called from), I just throw this wrapper around it and I get the traceback I need.

OK @glyph challenge accepted. Here is python programming talk.

I have a script that uses "with Popen(...,stdout=PIPE)" to run a program and roughly run grep. Now I'd like to add a timeout, but I don't want to buffer the output (because it is unbounded), so run is out. Currently I am running /usr/bin/timeout from python, but this is, uh, unpythonic.

I’m proud that my work is helping to make the #HugoAwards happen again this year. When you vote in the Hugo Awards, or download the packet, you're using software I wrote. It's open source -- a rarity in convention software, but in my opinion, so critical to the trust we must have in the process -- and made with #Python and #Django and many other software libraries that are also freely given to the developer community.
