A Retrospective on Requests - cat /dev/brain
After writing my thoughts on github3.py down here, someone was asking about Python libraries that people recommend new Python developers read for learning how to structure code and use the packaging systems. My initial reaction was "Don't listen to folks that tell you to read python-requests as a good example." When asked for explanation, I gave it but realized that most people only know that Requ
Neat parallel output in Python
Say you have a program that does some processing of a list (loosely based on a work-in-progress project): #!/usr/bin/env python3 def log(repo_name, *args): print(f"{repo_name}:", *args) def randsleep(): import random import time time.sleep(random.randint(1, 5)) def func(repo_name): log(repo_name, "Starting") randsleep() # Can be substituted for actual work log(repo_name, "Installing") randsleep()
Rye Grows With UV
written on February 15, 2024 Two weeks ago I asked the question again about What Rye should be. There has been one thing that I have not publicly shared before and that is that ever since Rye exists I have also been talking to Charlie Marsh about Python packaging and Python tooling. It turns out that we had some shared ideas of what an ideal Python tooling landscape would look like. That has lead
uv: Python packaging in Rust
TL;DR: uv is an extremely fast Python package installer and resolver, written in Rust, and designed as a drop-in replacement for pip and pip-tools workflows. uv represents a milestone in our pursuit of a "Cargo for Python": a comprehensive Python project and package manager that's fast, reliable, and easy to use. As part of this release, we're also taking stewardship of Rye, an experimental Python
A search engine in 80 lines of Python
February 05, 2024 · 9 mins · 1675 words Share on: X · HN Discussion on HackerNews. Last September I hopped on board with Wallapop as a Search Data Scientist and since then part of my work has been working with Solr, an open-source search engine based on Lucene. I’ve got the basics of how a search engine works, but I had this itch to understand it even better. So, I rolled up my sleeves and decided
Rye: A Vision Continued
written on February 04, 2024 In April of last year I released Rye to the public. Rye, both then and now, represents my very personal vision of what an improved Python packaging and project management solution can look like. Essentially, it’s a comprehensive user experience, designed so that the only tool a Python programmer would need to interface with is Rye itself and it gets you from zero to on
Python 3.13 gets a JIT
Happy New Year everyone! In late December 2023 (Christmas Day to be precise), CPython core developer Brandt Bucher submitted a little pull-request to the Python 3.13 branch adding a JIT compiler. This change, once accepted would be one of the biggest changes to the CPython Interpreter since the Specializing Adaptive Interpreter added in Python 3.11 (which was also from Brandt along with Mark Shann
Why if TYPE_CHECKING?
Dec 11 2023 I saw this tweet over the weekend and wanted to dive into the fundamental question behind this: Given this potential error, why do we use conditional imports at all, or, more specifically, when might we use this pattern? The TL;DR is that we use this pattern to hedge between the differences in typechecking enforced by mypy and typechecking as it happens at runtime, particularly when we
俺が考える最強の「麻雀点数申告練習アプリケーション」を作ってみる ~ Pythonによる麻雀点数計算問題の自動生成と音声による点数申告 ~ - エムスリーテックブログ
こちらはエムスリー Advent Calendar 2023 1日目の記事です。 Overview エムスリーエンジニアリンググループ AI・機械学習チームでソフトウェアエンジニアをしている中村(po3rin) です。趣味は麻雀でフリー雀荘で毎年200半荘以上打ちます。好きな麻雀プロは園田賢さんです。 麻雀を始めるときに一番の障壁になるのは点数計算ではないでしょうか？ 特に符計算が初心者の関門のようです。一方私のような初中級者でも突然のレアな点数申告にまごつくことがあります。 そこで、今回はその人に合った麻雀の点数計算問題(主に符計算が焦点となる問題)を生成して、自分で点数計算&点数申告の練習をする方法を探求したのでその紹介をします。麻雀用語が少しだけ登場するので、対象読者は麻雀を少しでもかじったことのあるエンジニアの方です。 Overview 麻雀の点数計算の難しさ 現状の点数計算の練習
Rust std fs slower than Python!? No, it's hardware!
I'm about to share a lengthy tale that begins with Apache OpenDAL™ op.read() and concludes with an unexpected twist. This journey was quite enlightening for me, and I hope it will be for you too. I'll do my best to recreate the experience, complete with the lessons I've learned along the way. Let's dive in! All the code snippets and scripts are available in Xuanwo/when-i-find-rust-is-slow TL;DRJum
Fixit 2: Meta’s next-generation auto-fixing linter
Fixit is dead! Long live Fixit 2 – the latest version of our open-source auto-fixing linter. Fixit 2 allows developers to efficiently build custom lint rules and perform auto-fixes for their codebases. Fixit 2 is available today on PyPI. Python is one of the most popular languages in use at Meta. Meta’s production engineers (PEs) are specialized software engineers (SWEs) who focus on reliability,
It's Time For A Change: datetime.utcnow() Is Now Deprecated
I was going through the release notes of the new Python 3.12 version the other day, and one item caught my attention in the deprecations section: datetime.datetime’s utcnow() and utcfromtimestamp() are deprecated and will be removed in a future version. If you have followed my web development tutorials you must have seen me use utcnow() a lot, so I will clearly need to re-train myself to use an al
