New article on my blog: a ORM technique I found for combining JSONObject and Subquery to build model instances: https://blog.bmispelon.rocks/articles/2024/2024-05-09-django-getting-a-full-model-instance-from-a-subquery.html

@CodenameTim @bmispelon That's really cool!

I don't have any particular insight into the performance implications I'm afraid - we'd need to do some profiling.

I'd love it if we could find a way to avoid needing the JSONObject intermediary though! I never worked on the SubQuery code, so I don't know what's possible there.

A former colleague had a tech interview with very nitpicky interviewers. Devs who continually nitpick in code review always puzzle me. The same people will happily use a thousand third-party deps without a care in the world for the code style and idioms used in those packages, databases, etc.

@caleb I think a big difference here is that they're not going to be reading or updating that upstream code anything like as often as the main codebase.

Python people, do you make short-lived intermediate variables to make your return statements readable?

For example, which of these would you tend to prefer?

def get_project_name(output_str): """Get project name from output of

@ehmatthes with a function this small I definitely prefer the second. I don't need the extra context from the name of the return value because it's in the function name. And I appreciate saving the vertical space.

💬 I have said this before, and I'll say it again... If not for GitHub’s popularity, no one would use git outside of the Linux kernel development. 🍿 https://social.jacobian.org/@jacob/112179743875942474

I started with mercurial, but my first job used git and I very quickly got used to it. I absolutely fell in love with the staging area and lightweight branches and while I understand there were ways to get similar things in mercurial, they weren't on by default so I never learnt them. To this day I'm a very happy git user.

It was glorious spending IRL time with old & new friends from #OpenSource / #Kubernetes / #Rust #RustLang / #Mastodon communities. I’m back in #NYC now!

I’m still processing everything, but I noticed some commonalities in the kinds of challenges #contributors are facing during this 2024 lonely burnout epoch (I’m not the only one who feels it right?)And I wonder if more #maintainers are facing them too.

So what are the toughest #community/ communications/ outreach challenges you’re tackling?

@haubles It was good to meet you, though I'm sad we didn't manage to meet up again so we could chat about the City of London!

Interesting question that was just raised in a talk:

Do we know of open source, third-party libraries being maintained by women?

@mahryekuh Thanks for the call out! Though we're not open source (yet?).

My students often ask me whether they can see a list of every dunder method that has. I've been meaning to compile a categorized list for years.

I finally did it.

Here's every dunder method in Python... all 115 of them! 🤯

@treyhunner

I found a mistake:

> where x < y would be the same as asking y >= x

These aren't the same when x == y.

lilyf,
@lilyf@fosstodon.org avatar

@treyhunner

> (x < y) == (not y >= x)

I think it should be:

(x < y) == (not x >= y)

It's really easy to get wrong, sadly!

I don't like setuptools, setup.py nor the directions it evolved to. I will continue to not use setuptools except when some tool only works when you add setup tools into the mix (cython, mypyc) and in that case, I will use something else for the things that don't have to be setuptools.

It is a solution for native code interop developers who have unlimited tolerance for great galloping complexity. That it makes c++ developers happy, I mean, good for them.

lilyf,
@lilyf@fosstodon.org avatar

@mistersql I don't think pipenv handles creating packages at all, so it's a bit strange to mention it here. If you meant on the installing side, both pipenv and poetry support interop via wheels.

I also wouldn't reach for setuptools unless I had some really weird requirements. For packaging Rust code I'd use maturin, for example, which is much simpler than setuptools. For a pure python package I might use flit.

lilyf,
@lilyf@fosstodon.org avatar

@mistersql Oh yeah, I'm glad running setup.py directly is dead. Personally I don't really care for most modern frontends (pipenv, poetry, etc). If I have a virtualenv I can install into with pip, I'm happy. For locking I like pip-tools. But any of this is better than setup.py.

I've decided to retire from being a Django Fellow at the end of March 2024. It's a great honor to be a Django Fellow. I've spent the last 5 years in my dream job 💚 🦄 but it's time to move forward 🔭 I'm not abandoning Django completely, nothing like that 🤗. I will continue to be an active member of our amazing Community and do my best to help it grow 💓

I'm open to new positions from April, 1st, so contact me if you need someone with my expertise 🤝

☕ Days since I spilled an entire mug of coffee all over my desk: 0

Somehow, everything works between the magic keyboard, cheap mouse, and many, many cables.

🤦 What. A. Mess.

I'm so excited for the next Django Cologne meetup 😁
It will be the 50th meetup (that's 1 a month for over 4 years!) 🎊 and to celebrate, we have special guests @sabderemane and @thibaudcolas (both DSF board and accessibility team members) to kick off a sprint and tell us all about future plans in Django 🔮 can't wait ❤️

It's Tuesday 23rd Jan, come if you're free!

I just published a new tool for managing Python interpreters and virtualenvs called lilyenv. It is written in Rust and can be installed via cargo install lilyenv.

I wrote lilyenv as a replacement for my previous workflow using virtualenvwrapper and pyenv. The main goal is to make it easy to manage virtualenvs when working on a library that needs to support multiple python versions.

https://crates.io/crates/lilyenv
https://github.com/LilyFoote/lilyenv

lilyf,
@lilyf@fosstodon.org avatar

@webology I don't think I've ever used virtualenvwrapper's hooks, so I'm not really sure if that would be in scope. I'm open to understanding the use cases though.

lilyf,
@lilyf@fosstodon.org avatar

@webology Hmm, the example of setting environment variables is interesting, but I think out of scope for now. I'd probably use direnv for that.

https://direnv.net/

lilyf,
@lilyf@fosstodon.org avatar

@webology If there's anything else in your specific workflow you think I should consider, please share!

lilyf,
@lilyf@fosstodon.org avatar

@CodenameTim activate will automatically download the python interpreter and create the virtualenv for you. I'll update the readme to clarify that.

According to Politico, Claudine Gay faced "plagiarism accusations" while Neil Gorsuch merely "borrowed" from other authors.

@mattsheffield I interpreted "borrowed" as "he definitely did it" and "faces accusations" as "she maybe did it". Interesting how different people read different implications here.

I really enjoyed the latest episode of @djangochat with @lilyf. I appreciate her openness on how she approaches contributing. It's always great to get to know people better, see how they think and what challenges interest them.

I was laughing pretty good when Lily talked about her experience with typing in python while being as diplomatic as possible.

lilyf,
@lilyf@fosstodon.org avatar

@CodenameTim @djangochat I'm glad you enjoyed it!

lilyf,
@lilyf@fosstodon.org avatar

@webology @CodenameTim @djangochat I haven't actually done any significant work on a typed Django project. My experience with typing is mostly from Kolo itself and the pain points were mostly mypy.

lilyf,
@lilyf@fosstodon.org avatar

@webology @CodenameTim @djangochat I've just had a quick look at Typer and I have a few thoughts.

The first is that using python type hints as input to a library is pretty cool and not what I'm criticising about python's typing.

The second is that once you get beyond simple examples, I don't really see an improvement over using Click directly. For example, when adding a help message for a specific option, the type hinting approach gets about as noisy as Click's decorator approach.
