We are delighted to introduce Spin 1.0, the first stable release of the open source developer tool for building serverless applications with WebAssembly (Wasm)! Since we first introduced Spin last year, we have been hard at work together with the community on building a frictionless developer experience for building and running serverless applications with Wasm. For this release, we focused on bui

In order to create a Python package, you need to write the code that implements the functionality you want to put in your package, and then you need to publish it to PyPI. That is the bare minimum. Nowadays, you can also set up a variety of other things to make your life easier down the road: continuous testing of your package;
開発品質とDeveloper eXperienceを高めるコンテナ開発環境のご紹介 (Python) - ABEJA Tech Blog
はじめに こんにちは 2023年1月に入社し、システム開発グループでエンジニアをしてる春名です。 私の所属しているシステム開発グループでは、開発初期の環境構築をより効率的に行うための活動に取り組んでいます。 今回はそのうちの一つである、Pythonでコンテナ開発をする環境を構築した内容をご紹介します。 なぜコンテナ開発環境かと言いますと、単にAWSのECSやGoogle CloudのCloud Runを使ってデリバリーする案件が多いからです。 より使用頻度の高い開発環境を整備し、テンプレート化しておくことで開発の効率化に活用しています。 2025/12/19 追記 最新のPython開発環境を以下の記事でご紹介しています！ tech-blog.abeja.asia 本記事の内容もご参考にいただきつつ、最新の情報をご確認ください🚀 目次 はじめに 目次 今回作成する環境 Poetryによる
Astral builds tools that millions of developers around the world depend on and trust. That trust includes confidence in our security posture: developers reasonably expect that our tools (and the processes that build, test, and release them) are secure. The rise of supply chain attacks, typified by the recent Trivy and LiteLLM hacks, has developers questioning whether they can trust their tools. To
I first learned Kubernetes ("k8s" for short) in 2018, when my manager sat me down and said "Cloudflare is migrating to Kubernetes, and you're handling our team's migration." This was slightly terrifying to me, because I was a good programmer and a mediocre engineer. I knew how to write code, but I didn't know how to deploy it, or monitor it in production. My computer science degree had taught me a

The Go Programming Language and Environment – Communications of the ACM
Go is a programming language created at Google in late 2007 and released as open source in November 2009. Since then, it has operated as a public project, with contributions from thousands of individuals and dozens of companies. Go has become a popular language for building cloud infrastructure: Docker, a Linux container manager, and Kubernetes, a container deployment system, are core cloud techno
Tiny Core Linux 13.0 is a full Linux desktop in 22 MB #Linux
February 11, 2022 AT 9:40 am Tiny Core Linux 13.0 is a full Linux desktop in 22 MB #Linux Most Linux-based operating systems are fairly large — usually well over a full gigabyte in size for the base install image. Tiny Core Linux, which clocks in at a svelte 22 MB download, just released version 13. It’s fast. And another neat trick: “Unlike most operating systems, the Tiny Core can run completel
Boring Python: code quality
Boring Python: code quality December 19, 2022 Django, Python This is the second in a series of posts I intend to write about how to build, deploy, and manage Python applications in as boring a way as possible. In the first post in the series I gave a definition of what I mean by “boring”, and it’s worth revisiting: I don’t mean “reliable” or “bug-free” or “no incidents”. While there is some overla
Using skills to accelerate OSS maintenance | OpenAI Developers
Keep workflows in the repo In these repos, we use skills to capture repository-specific workflows. A skill is a small package of operational knowledge: a SKILL.md manifest, plus optional scripts/, references/, and assets/. The Codex customization docs describe why this works well: skills are a good fit for repeatable workflows because they can carry richer instructions, scripts, and references wit
GIMP 2.99.12 is a huge milestone towards GIMP 3.0. Many of the missing pieces are getting together, even though it is still a work in progress. As usual, issues are expected and in particular in this release which got important updates in major areas, such as canvas interaction code, scripts, but also theming… “CMYK space invasion”, by Jehan (based on GPLv3 code screencast), Creative Commons by-sa

We're announcing two new security features for uv: uv audit is a new command that scans your dependencies for known vulnerabilities and "adverse" project statuses (such as being deprecated). It's a uv-native alternative to pip-audit, and is between 4x and 10x1 faster on typical projects. uv add, uv sync, etc. can now perform a lightweight OSV-based lookup for previously-resolved malware on every s
TL;DR: Install mambaforge, use mamba to install packages, and pin direct dependencies inside your environment.yml.

The Twelve-factor app is a methodology for building software-as-a-service apps that was first formulated by developers associated with Heroku. It's been ten years since the first presentation of this methodology. Despite the criticism that it is only applicable to Heroku and similar webapp services, it remains a relevant yard stick for software-as-a-service development. Some of its tenets have bee
State of Text Rendering 2024
Preface In 2009 I wrote State of Text Rendering, as a high-level review of the Free Software text rendering stack, with a focus on shaping, and mostly in the context of the GNOME Desktop. Since then, I have spent around twelve years working on various Google products to improve fonts and text rendering: all Open Source work. When I wrote that text in 2009, my main assignment was to finish HarfBuzz
Python is a wonderful programming language. I’ve used it to build webapps, deep learning models, games, and do numerical computation. However there is one aspect of Python that has been an inexcusable pain-in-the ass over many years. That would be the fragmented Python package and environment management ecosystem, succinctly represented by the following XKCD comic: You see, a lot of other programm
Intro This guide is intended for people who are already familiar with Python 3 and looking to start a new project. This guide comes from experience building api backends for a variety of startups in different industries, it serves as a starting point for what the state of “best practise” is for how I think about organising Python projects, structuring code, testing, and common libraries I’ve reuse

How we built a VS Code extension with Rust, WebAssembly, and TypeScript We build Oso, a batteries-included framework for building authorization in your application. At the core of Oso is Polar, a declarative language for writing authorization policies. While someday we’ll release a feature that lets a fully-sentient Oso write your authorization policy for you, in the interim we thought it would be

【AI】進化的マージモデルを手軽に作れる「mergekit」というツール | IIJ Engineers Blog
進化的マージモデルとは？ これは、Sakana.aiさんが2024年3月21日発表した、「進化的アルゴリズムによる基盤モデルの構築」で述べられた手法を用いて作られたLLMを指しています。 引用すると、「多様な能力を持つ幅広いオープンソースモデルを融合して、新たな基盤モデルを構築するための方法を、進化的アルゴリズムを用いて発見する手法」であるとのことで、その中でも生成されたLLMの一つである EvoLLM-JP は融合元に指定したモデルはベンチマーク成績があまり芳しくないにもかかわらず、融合後のモデルはGPT-3.5に迫る性能を叩き出しました。 Sakana.aiさんでは、その後言語画像モデルとしてEvoVLM-JPを、日本語画像生成モデルとしてEvoSDXL-JPをリリースしています。 今日の人工知能を形作る「モデル」には、モデルを構成する要素に紐付く「重みパラメータ・バイアスパラメータ」

Python package versions seem simple on the surface because we're used to seeing the common and well-defined version schemes like SemVer (1.2.3) or CalVer (2023.6.1) and occasionally a pre-release suffix (1.2.3pre1). But Python package versioning can get much more complicated than that! 🤯 Below is a list of quirks in Python package versioning you may not know about: What is a Python package versio
I started using uv because the benchmarks seemed too good to be true—10–100x faster than pip, resolves and installs in milliseconds. After reading the source code and the official resolver internals documentation, I understand why, and the answers are more interesting than just "it's written in Rust." This post traces every layer: from the repository structure, through what literally happens when

As such, interviews for Python-related positions are designed not on
Me after years using python.Before starting this post, I want to acknowledge that soft and hard skills are equally important. Data people exist to deliver business value, or more broadly read facts from a pool of ever-growing data. But, even with a bunch of posts talking about soft skills, at the end of the day, we're being paid for the technical skills we have, and the ability we have to deliver
