written on June 12, 2025 There is currently an explosion of people sharing their experiences with agentic coding.

レッドハットの杉村です。Ansible のテクニカルサポートをしています。 今回は以前のお問い合わせいただいた事例から、SSH (Secure Shell Protocol) について一つ紹介しようと思います。Ansible は Linux サーバを制御対象とするときは SSH で接続して処理を実行しますので、SSH の通信についてのトラブルは問題に直結します。 RHEL 8.6 + Ansible Core 2.13 で確認しています。 Ansible の基本的な動作原理 まずは Ansible はどうやって動いているのかというのを軽く振り返ってみます。 Ansible が動作するサーバをコントロールノード、制御対象をマネージドノードと呼びます。流れを大まかに説明しますと、この図のようになります。 ① YAMLで書かれたプレイブックからタスクごとに小さなプログラムを生成する ② ①で生成

Lessons from Writing a Compiler
The prototypical compilers textbook is: 600 pages on parsing theory. Three pages of type-checking a first-order type system like C. Zero pages on storing and checking the correctness of declarations (the “symbol table”). Zero pages on the compilation model, and efficiently implementing separate compilation. 450 pages on optimization and code generation. The standard academic literature is most use

Photo by Claudio Schwarz on Unsplash. How to create a Python package? 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;
Today we’re excited to announce the release of TypeScript 4.8! If you’re not yet familiar with TypeScript, it’s a language that builds on JavaScript and adds syntax for types. These types let you put your expectations and assumptions into your code, and those assumptions can then be checked by the TypeScript type-checker. This checking can help avoid typos, calling uninitialized values, mixing up
Today we’re excited to announce the release of TypeScript 5.2! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by making it possible to declare and describe types. Writing types in our code allows us to explain intent and have other tools check our code to catch mistakes like typos, issues with null and undefined, and more. Types also power TypeScript’s edi
Notable changes built-in .env file support Starting from Node.js 20.6.0, Node.js supports .env files for configuring environment variables. Your configuration file should follow the INI file format, with each line containing a key-value pair for an environment variable. To initialize your Node.js application with predefined configurations, use the following CLI command: node --env-file=config.env
This blog post hopes to convince you that Python is a compiled language. And by “Python”, I don’t mean alternate versions of Python like PyPy, Mypyc, Numba, Cinder, or even Python-like programming languages like Cython, Codon, Mojo1—I mean the regular Python: CPython! The Python that is probably installed on your computer right now. The Python that you got when you searched “python” on Google and

The exact context and severity of these vulnerabilities varied, but some

Update: I originally published this post few months ago, and it only covered Turbo Drive and Turbo Frames then, with a static site. I've since had a bunch of conversations with people working with other tech stacks (Rust, PHP, and Go) wanting to integrate Hotwire into their front-ends, and everyone kept asking about Turbo Streams, since it needs a back-end server. So I've updated the post to build
Accelerate Python code 100x by import taichi as ti | Taichi Docs
Python has become the most popular language in many rapidly evolving sectors, such as deep learning and data sciences. Yet its easy readability comes at the cost of performance. Of course, we all complain about program performance from time to time, and Python should certainly not take all the blame. Still, it's fair to say that Python's nature as an interpreted language does not help, especially

Python behind the scenes #13: the GIL and its effects on Python multithreading
As you probably know, the GIL stands for the Global Interpreter Lock, and its job is to make the CPython interpreter thread-safe. The GIL allows only one OS thread to execute Python bytecode at any given time, and the consequence of this is that it's not possible to speed up CPU-intensive Python code by distributing the work among multiple threads. This is, however, not the only negative effect of
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

If you are a Rubyist, you’ve likely been writing # frozen_string_literal: true at the top of most of your Ruby source code files, or at the very least, that you’ve seen it in some other projects. Based on informal discussions at conferences and online, it seems that what this magic comment really is about is not always well understood, so I figured it would be worth talking about why it’s there, w
