Obsidian for markdown and support for mermaid together with a coding agent has been absolutely wonderful for creating timeplans. The agent pulling data from multiple excel files and creating a unified plan. Also having it update the mermaid Gant charts as people fire off new things in meetings

While I built multiple applications and packages at home and work, this is the first time I pushed something to pypi!🥳 It was inspired by this episode of @pythonbytes.fm: pythonbytes.fm/episodes/sho... Where Michael said someone should build a package based on a blog post covered. Well here we go!

I think this is a really good point from @jamellebouie.net. I find outsourcing the formation of my view on a topic to an LLM a scary proposition. This is also why I'm a bit wary around coding assistants. When am I outsourcing so much of my thinking that it impacts my understanding of the problem?

Thanks to @willmcgugan.bsky.social and the textualize team for this time. Textual seems to be a TUI library that is second to none, python or otherwise. I'm sad that the company didn't work out, but glad that you gave it a go as textual made me fall in love with the terminal applications

Seeing PEP-735, Dependency Groups, included in the latest version pip makes me really happy! With both uv and pip supporting them I'm pretty sure I can move away completely from requirements.txt 🥳

peps.python.org

PEP 735 – Dependency Groups in pyproject.toml | peps.python.org

This PEP specifies a mechanism for storing package requirements in pyproject.toml files such that they are not included in any built distribution of the project.

I would generally agree with this perspective on LLMs. To me the aggressive stance against there usefulness looks more like a counter reaction against the hype. Are they as useful as the hype-side tries to tell you, absolutely not. Are they useless, also no.

Tried out asdf yesterday, mainly to manage erlang and elixir. Feels like it would have been nice if plugins could manage build dependencies for you. Copy-pasting the install commands from the readme obviously wasn't hard, but increased the friction slightly

Beside the changing table we have a box of baby socks. I found 3 socks, non of which where equal to the others. Looking around I found another one, which obviously didn't match the other 3. I gave up and started on a new pair, guess I will find 5 non-matching socks the next time ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯

Not doing much serveless stuff, but it sounds interesting. I have been playing around with duckdb for some larger than memory data and it's been pretty great. Was running queries over piles of parquet files 😁

I checked out the repo and I would say that pyproject.toml or setup.cfg is the preferred way to configure setuptools now a days. Generally, using static information instead of a build script makes packages safer and more easily introspected. Personaly, I prefer pyproject.toml as it's standardized

110

Fredrik Sjöstrand @fronkan.bsky.social · 14/03/2025

I would for example use `pyproject.toml` for the package information rather than `setup.cfg` and defently avoid `setup.py`. `setup.py` is powerful but we try to use static information now a days. Pyproject.toml is the latest and most standardised way, making it easier to try other build systems.

000

Fredrik Sjöstrand @fronkan.bsky.social · 14/03/2025

Now a day's we have a lot of options for building packages, but, for a long time setuptools was more or less the only option. It's been around for a long time and things has changed quite a bit during that time. So if you use it, just make sure to see what current practice is.

100

Fredrik Sjöstrand @fronkan.bsky.social · 13/03/2025

Built a few packages using setuptools but never published anything to pypi. Just company internal stuff. I don't know how uv shakes things up but, previously I have heard good things about flit (flit.pypa.io/en/latest/in...) for pure python packages.

Python is a "language for consenting adults". We tell you with a single leading underscore that you shouldn't touch it and trust that you understand the implied risk of using it.

000

Fredrik Sjöstrand @fronkan.bsky.social · 21/02/2025

The leading double underscore will cause name mangling, a feature that is nice for avoiding naming conflicts when doing inheritance. In practice I very rarely see this used. It's slightly more annoying to get to because of it but it's not private in any strict sense.

Fredrik Sjöstrand @fronkan.bsky.social · 21/02/2025

Came across a poll on linked-in on how to create private fields and methods in Python. Almost 50% of the over 1100 respondents picked __my_var. The technically correct answer of "private, what do you mean private?" didn't exist 🧐 and _my_var, what I believe is industry practice was way lower 🤔

Day 1 of parental leave and things are going very well. First time having her in the stroller while shoveling snow and it went flawlessly 😄 And with a path cleared, we could take a walk with the stroller for the afternoon nap 😴

I felt like I was guided through todays #adventofcode. From the start I knew what bart 2 would be, but the problem felt difficult. So I focused on doing that part and when I came to the second part I could see the solution very clearly. Just build out from the checking code and problem solved 😊

Fredrik Sjöstrand @fronkan.bsky.social · 04/12/2024

Well, then I should write up the correct way to use the recursive operator in yq to replace values in nested YAML. Because it got it wrong and it would be nice if it gets it right when I, inevitably, have to ask it again 😅

010

Fredrik Sjöstrand @fronkan.bsky.social · 02/12/2024

Although, it was for sure the wrong move in this case 😅 Breaking it out, for sure was the correct abstraction and I knew it. I just thought it would be fine 😛

Fredrik Sjöstrand @fronkan.bsky.social · 02/12/2024

I just want to add that this doesn't make me a die hard fan of DRY (Don't repeat yourself). While generally pretty good advice, it can also lead to you implementing the wrong abstractions. This often manifest in functions with different modalities. I personally like WET (Write everything twice)

Accidentally woke up early today, so 2/2 days on #adventofcode. This is going way better than expected 😁
