Microsoft Power Automate DesktopでRPAを実現してみる | 🌴 officeの杜 🥥
自分自身の個人的意見としては、エンドユーザコンピューティングは大いに結構だと思ってるけれど、一方で日本でジリジリと熱さが消えつつある国内の有象無象のRPAについては滅んだほうが良いとも思ってる。理由は後述するとして、本日良いニュースが発表されました。Power Automate Desktopについて追加費用無し無償で利用可能になるとのこと。これは既にあるMicrosoft365のEnterpriseプランなどに標準で利用できてるPower Automateのデスクトップ版のようで、Windows10に標準でついてくるようになるとのこと。 ということで、現時点のMicrosoft365で使えてるPower Automate Desktopを使ってみて、どんな感じなのか？またリリース後にその違いなどをここに記述していこうかなと思っています。また、Seleniumベースのウェブ自動化についても

Fish 4.0: The Fish Of Theseus
About two years ago, our head maintainer @ridiculousfish opened what quickly became our most-read pull request: #9512 - Rewrite it in Rust Truth be told, we did not quite expect that to be as popular as it was. It was written as a bit of an in-joke for the fish developers first, and not really as a press release to be shared far and wide. We didn’t post it anywhere, but other people did, and we go
January 30, 2023 In this post, we'll implement a GPT from scratch in just 60 lines of numpy. We'll then load the trained GPT-2 model weights released by OpenAI into our implementation and generate some text. Note: This post assumes familiarity with Python, NumPy, and some basic experience with neural networks. This implementation is for educational purposes, so it's missing lots of features/improv
Introducing Ezno
Ezno is an experimental compiler I have been working on and off for a while. In short, it is a JavaScript compiler featuring checking, correctness and performance for building full-stack (rendering on the client and server) websites. This post is just an overview of some of the features I have been working on which I think are quite cool as well an overview on the project philosophy ;) It is still

型安全かつシンプルなAgentフレームワーク「PydanticAI」の実装を解剖する - ABEJA Tech Blog
はじめに こちらはABEJAアドベントカレンダー2024 12日目の記事です。 こんにちは、ABEJAでデータサイエンティストをしている坂元です。最近はLLMでアプローチしようとしていたことがよくよく検証してみるとLLMでは難しいことが分かり急遽CVのあらゆるモデルとレガシーな画像処理をこれでもかというくらい詰め込んだパイプラインを実装することになった案件を経験して、LLMでは難しそうなことをLLM以外のアプローチでこなせるだけの引き出しとスキルはDSとしてやはり身に付けておくべきだなと思うなどしています（LLMにやらせようとしていることは大抵難しいことなので切り替えはそこそこ大変）。 とはいうものの、Agentの普及によってより複雑かつ高度な推論も出来るようになってきています。弊社の社内外のプロジェクト状況を見ていても最近では単純なRAG案件は減りつつあり、計画からアクションの実行、結果

Rewriting the Ruby parser
At Shopify, we have spent the last year writing a new Ruby parser, which we’ve called YARP (Yet Another Ruby Parser). As of the date of this post, YARP can parse a semantically equivalent syntax tree to Ruby 3.3 on every Ruby file in Shopify’s main codebase, GitHub’s main codebase, CRuby, and the 100 most popular gems downloaded from rubygems.org. We recently got approval to merge this work into C

4 Pandas Anti-Patterns to Avoid and How to Fix Them
pandas is a powerful data analysis library with a rich API that offers multiple ways to perform any given data manipulation task. Some of these approaches are better than others, and pandas users often learn suboptimal coding practices that become their default workflows. This post highlights four common pandas anti-patterns and outlines a complementary set of techniques that you should use instea
written by Ruud van Asseldonk published 11 January 2023 For a data format, yaml is extremely complicated. It aims to be a human-friendly format, but in striving for that it introduces so much complexity, that I would argue it achieves the opposite result. Yaml is full of footguns and its friendliness is deceptive. In this post I want to demonstrate this through an example. This post is a rant, and

Weird Lexical Syntax
I just learned 42 programming languages this month to build a new syntax highlighter for llamafile. I feel like I'm up to my eyeballs in programming languages right now.

The languages I decided to support are Ada, Assembly, BASIC, C, C#, C++, COBOL, CSS, D, FORTH, FORTRAN, Go, Haskell, HTML, Java,

Why Rust strings seem hard April 13, 2021 Lately I've been seeing lots of anecdotes from people trying to get into Rust who get really hung up on strings (&str, String, and their relationship). Beyond Rust's usual challenges around ownership, there can be an added layer of frustration because strings are so easy in the great majority of languages. You just add them together, split them, whatever!

Most of my readers are probably familiar with procedural programming, object-oriented programming (OOP), and functional programming (FP). The majority of top programming languages on all of the language popularity charts (like TIOBE) support all three to some extent. Even if a programmer avoided one or more of those three paradigms like the plague, they’re likely at least aware of them and what th
This blog tries to summarize all the choices and paths you could take to implement your next programming language, more specifically the frontend for your language.

Agentic GraphRAG for Commercial Contracts | Towards Data Science
In every business, legal contracts are foundational documents that define the relationships, obligations, and responsibilities between parties. Whether it’s a partnership agreement, an NDA, or a supplier contract, these documents often contain critical information that drives decision-making, risk management, and compliance. However, navigating and extracting insights from these contracts can be a

👋 This page was last updated ~3 years ago. Just so you know. In the two years since I’ve posted I want off Mr Golang’s Wild Ride, it’s made the rounds time and time again, on Reddit, on Lobste.rs, on HackerNews, and elsewhere. And every time, it elicits the same responses: You talk about Windows: that’s not what Go is good at! (Also, who cares?) This is very one-sided: you’re not talking about th
2025-05-06, Version 24.0.0 (Current), @RafaelGSS and @juanarbol We’re excited to announce the release of Node.js 24! This release brings several significant updates, including the upgrade of the V8 JavaScript engine to version 13.6 and npm to version 11. Starting with Node.js 24, support for MSVC has been removed, and ClangCL is now required to compile Node.js on Windows. The AsyncLocalStorage API
This post is an account of why I prefer using the attrs library over Pydantic. I'm writing it since I am often asked this question and I want to have something concrete to link to. This is not meant to be an objective comparison of attrs and Pydantic; I'm not interested in comparing bullet points of features, nor can I be unbiased since I'm a major contributor to attrs (at time of writing, second
Lately I’ve been messing around with Python 3.12, discovering new features around typing and pattern matching. Combined with dataclasses, they provide support for a style of programming that I’ve employed in Kotlin and Typescript at work. That style in turn is based on what I’d do in OCaml or Haskell, like modelling data with algebraic data types. However, the more advanced concepts from Haskell —
Since I was unable to travel for a couple of years during the pandemic, I decided to take my new-found time and really lean into Rust. After writing over 100k lines of Rust code, I think I am starting to get a feel for the language and like every cranky engineer I have developed opinions and because this is the Internet I’m going to share them. The reason I learned Rust was to flesh out parts of t
Delimiter-first code
Summary I argue for wider usage of delimiter-first in the code three friends [tic, tac, toe] becomes three friends ・tic ・tac ・toe. A new top-level syntax for programming languages is proposed to show advantages of this method. New syntax is arguably as simple, but more consistent, better preserves visual structure and solves some issues in code formatting. Related: comma-first formatting A well-kn

Introduction Before explaining why I created Oil, let's review what it is. You can think of a Unix shell in two ways: As a text-based user interface. You communicate with the operating system by typing commands. As a language. It has variables, functions, and loops. Shell programs are text files that start with #!/bin/sh. In this document, we'll think of Unix shells as languages. The Oil project a
