The rich console is themeable, I’ve been a long time user of rich and had no Idea. You can define your own theme keywords and use them just like you use normal rich keywords in square brackets like'[bold red]'. from rich.console import Console from rich.theme import Theme custom_theme = Theme({ "info": "dim cyan", "warning": "magenta", "danger": "bold red" }) console = Console(theme=custom_theme) console.print("This is information", style="info") console.print("[warning]The pod bay doors are locked[/warning]") console.print("Something terrible happened!", style="danger")

The adapter pattern in python The Adapter pattern is a design pattern that allows objects with incompatible interfaces to work together. It provides a way to convert the interface of an object into another interface that client... Rob Parsons · robp.dev [1] This has me wondering if I need to really learn more patterns, data structures, and algorithms. This looks particularly useful when trying to combine several objects that you dont have full control over and make them behave similarly. Note This post is a thought [2].

I’m trying to replace my usage of google inline search apps with real apps, today I used a stopwatch to time some things out at work by opening stopwatch. This was something I just wanted running in a tab on another screen, it was not timing running code or anything, I was using it as a reminder to check browser caches every 5 minutes or so for some testing. So tonight I whipped up a stopwatch [1], clock [2] and timer [3], all of which are using the wakelock API to keep the screen on while the app is running. // Wake Lock support let wakeLock = null; async function requestWakeLock() { try { if ('wakeLock' in navigator) { wakeLock = await navigator.wakeLock.request('screen'); console.log("Wake lock acquired"); } } catch (err) { console.error("Wake lock error:", err); } } document.addEventListener("visibilitychange", () => { if (wakeLock !== null && document.visibilityState === "visible") { requestWakeLock(); } }); requestWakeLock(); References: [1]: https://stopwatch.wayl.one [2]: https://clock.wayl.one [3]: https://timer.wayl.one

I’ve been using ruff to lint my python code for quite awhile now, I was pretty early to jump on it after release. Some of my projects have had a nice force-single-line setting and some have not. I dug into the docs and it was not clear what I needed to make it work. [tool.ruff] select = ['I'] # you probably want others as well [tool.ruff.isort] force-single-line = true Turns out I was missing Isort in the select list.

- Astral is doing great things in the python industry. They are disrupting entire categories of tools with extremely fast, easy to use, and feature rich alternatives that make it really hard to keep using the incumbent. So far I am seeing no signs of evil, sometimes with such a disrupter there is some sort of downside that make it hard to want to do the switch. In the interview they even mention things like leaning on lsp so that it works across all editors rather than building out vscode integrations that work for most developers. As a neovim user I greatly apreciate this. Note This post is a thought [1]. It’s a short note that I make about someone else’s content online #thoughts References: [1]: /thoughts/

Playground | ty An in-browser playground for ty, an extremely fast Python type-checker written in Rust. types.ruff.rs [1] ty, has a playground running at types.ruff.rs. You can edit code in there and see what the type checker results would be in browser. This looks good, excited to see it running in my lsp. Here is an example where a Optional may not be defined.

I was looking back at my analytics [1] page today and wondered what were my posts about back at the beginning. My blog is managed by markata [2] so I looked at a few ways you could pull those posts up. Turns out it’s pretty simple to do, use the markata map with a filter. from markata import Markata m.map('title, slug, date', filter='date.year==2016', sort='date') Note the filter is python eval that should evaluate to a boolean, all of the attributes of the post are available to filter on. Result # [3] [ ('⭐ jupyterlab jupyterlab', 'jupyterlab-jupyterlab', datetime.date(2016, 12, 13)), ('⭐ nickhould tidy-data-python', 'nickhould-tidy-data-python', datetime.date(2016, 12, 9)), ( '⭐ mikeckennedy write-pythonic-code-demos', 'mikeckennedy-write-pythonic-code-demos', datetime.date(2016, 11, 22) ), ( '⭐ mikeckennedy write-pythonic-code-for-better-data-science-webcast', 'mikeckennedy-write-pythonic-code-for-better-data-science-webcast', datetime.date(2016, 11, 22) ), ('⭐ rajshah4 dlgroup', 'rajshah4-dlgroup', datetime.date(2016, 11, 18)), ('⭐ pandas-dev pandas', 'pandas-dev-pandas', datetime.date(2016, 10, 5)) ] You could use the list command as well right within y...

I run tailwind for my personal blog, whenever I update it, pre-commit goes in and fixes end of file.

Client Challenge pypi.org [1] python bindings for valkey, forked from redis. one notable difference I see from redis is that you can install with libvalkey to autmatically get faster parsing support. For faster performance, install valkey with libvalkey support, this provides a compiled response parser, and for most cases requires zero code changes. By default, if libvalkey >= 2.3.2 is available, valkey-py will attempt to use it for response parsing. pip install "valkey[libvalkey]" Note This post is a thought [2].

[1] Migrating from kedro 0.18.4 to the latest version involves handling the deprecated OmegaConf loader. Switching over does not look as bad as I originally thought. - installing kedro 0.18.5+ - set the CONFIG_LOADER_CLASS in settings.py - swap out import statements - config must be yaml or json - getting values from config must be done with bracket __getattr__ style not with .get - any Exceptions caught from Templated config loader will need to be swapped to OmegaConfig exceptions, similar to #3 - templated values must lead with an _ - Globals are handled different - OmegaConfig does not support jinja2 sytax, but rather a ${variable} syntax Note This post is a thought [2].

Models Pydantic Docs · docs.pydantic.dev [1] I came accross from_attributes today it allows creation of pydantic models from objects such as a sqlalchemy Base Model or while nesting pydantic models. I believe in the past I have ran into some inconsistencies with nesting pydantic models and I’ll bet one had from_attributes set and another did not. Arbitrary class instances¶ (Formerly known as “ORM Mode”/from_orm). Pydantic models can also be created from arbitrary class instances by reading the instance > attributes corresponding to the model field names. One common application of this functionality is integration with object-relational mappings (ORMs). To do this, set the from_attributes config value to True (see the documentation on Configuration for more details). The example here uses SQLAlchemy, but the same approach should work for any ORM.
