Gitingest has a python package on pypi that you can run with uvx, and it accepts the same arguments as the web version, right in your terminal

kitze hating on python packaging in new ways. Python packaging has a lot of quirks that can make it infuriating. Not once have I thought “you know what this needs, quotes and braces”

Great list of 4 tips for running fastapi applications.

Fat routers with all of the logic built in makes them hard to test, hard to refactor, causes lots of duplication, and makes it hard to reuse the business logic code later in something like a cli application.

I really like this advice! He reccommends deploying as early as you can get a healthcheck live in your application. I’ve found too many times developers build something that is really hard, or impossible to deploy, when if they had tried to deploy early they would have spotted some easy to fix issues. This is less important if you are building out of a template that your team commonly deploys from, but very important with new patterns.

This is really interesting, the lazy uv scripts are really becoming quite appealing, especially for something like this to just pop out of an llm ready to run. The article features several examples of these one-shot prompt ideas that I suggest you give a try, and a prompt for creating them.

PEP 723 is what is inspiring all of these lazy self installing python scripts, Authored by the author of hatch and pyapp. This is a really cool thing that uv has picked up and made python packaging just a bit easier.. maybe… dependency resolution still sucks.

I’ve kinda fallen out of using direnv now that a lot of my projects use hatch, I generally just hatch shell into them. I just need to make sure I go through all of them and make my installer uv. Now I’ve been thinking about making uv my only needed dependency to run a python project and leaning more to something like uv run --with . uvicorn myapp --reload

I really like Trey’s steps to making an executable python script with uv

his old process seems to be the same with a new shebang

And here is the new format the the shebang followed by the metadata comment block defined in PEP 723.

Nice example of adding a healthcheck to fastapi, and integrating it with docker. Don’t forget to include curl in the install, nice touch.

Simple, modern and high performance file watching and code reload in python.

I’ve been playing with 3d printing some items through the slant3d api. I’ve been pricing out different prints by running a slice request through their api.

I’ve been using uv for project management. It’s been working well for quick projects like this while making it reproducible, I’m still all in on hatch for libraries.

mkdir slantproject cd slantproject uv init uv venv . ./.venv/bin/activate uv add httpx rich python-dotenv

Get an api key #

You will need an api key from the slant api, which currently requires a google account and a credit card to create.

# .env # replace with your api key from https://api-fe-two.vercel.app/ SLANT_API_KEY=sl-**

slicing an stl with teh slant api #

Then you can run the python script to price out your print. I’m not exactly sure how this compares to an order, especially when you add in different materials.

Hynek has a sick dockerfile setup for using uv in python projects.

SQLModel models ship with an is_, and is_not that you can use to compare to None without pesky linters complaining.

This comment summed it up quite well.

I believe this is concerned entirely with SQLAlchemy, not with SQLModel, and has to do with the required semantics to construct a BinaryExpression object. Hero.age == None evaluates to a BinaryExpression object which is eventually used to construct the SQL query that the SQLAlchemy engine issues to your DBMS. Hero.age is None evaluates to False immediately, and not a BinaryExpression, which short-circuits the query no matter the value of age in a row. From a cursory search, it does not seem that the is operator can be overridden in Python. This could help explain why the only possibility is by using the == operator, which can be overridden.

so rather than using Team.heros == None we can use Team.seros.is_(None) which checks for itentity not equality.

Today I learned that you cannot pass negative integers as values to typer. in this case context_settings={"ignore_unknown_options": True} is required so that the - does not look like a flag.

This new demo of textual is wildly awesome, so many widgets and features being added into the main library. The themes and animations are on point and far surpass my expectations of a tui.
