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

[Hacker News discussion, LinkedIn discussion, Twitter thread] Update: My upcoming book, AI Engineering (late 2024/early 2025) will cover building aplications with foundation models in depth. A question that I’ve been asked a lot recently is how large language models (LLMs) will change machine learning workflows. After working with several companies who are working with LLM applications and persona

A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog

But first: A JavaScript label should not be c
Weird Lexical Syntax

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

Parsing SQL - Strumenta
The code for this tutorial is on GitHub: parsing-sql SQL is a language to handle data in a relational database. If you worked with data you have probably worked with SQL. In this article we will talk about parsing SQL. It is in the same league of HTML: maybe you never learned it formally but you kind of know how to use it. That is great because if you know SQL, you know how to handle data. However

Patterns for Building LLM-based Systems & Products [ llm engineering production 🔥 ] · 66 min read Discussions on HackerNews, Twitter, and LinkedIn “There is a large class of problems that are easy to imagine and build demos for, but extremely hard to make products out of.

Introduction HTML, the programming language, is a practical, turing-complete[1], stack-based programming language based on HTML, the markup language. It uses elements defined in HTML, the markup language, in order to do computations. To give you a sense of what HTML, the programming langauge, looks like, below is a sample program that prints the values from 1 to 10 to standard out (console.log) A
Why People are Angry over Go 1.23 Iterators - gingerBill
NOTE: This is based on, but completely rewritten, from a Twitter post: https://x.com/TheGingerBill/status/1802645945642799423 TL;DR It makes Go feel too “functional” rather than being an unabashed imperative language. I recently saw a post on Twitter showing the upcoming Go iterator design for Go 1.23 (August 2024). From what I can gather, many people seem to dislike the design. I wanted to give m

Why async Rust?
Async/await syntax in Rust was initially released to much fanfare and excitement. To quote Hacker News at the time: This is going to open the flood gates. I am sure lot of people were just waiting for this moment for Rust adoption. I for one was definitely in this boat. Also, this has all the goodness: open-source, high quality engineering, design in open, large contributors to a complex piece of

Here are my highlights, including a dive into the leaked tool prompts that Anthropic did
research!rsc: Updating the Go Memory Model (Memory Models, Part 3)
The current Go language memory model was written in 2009, with minor updates since. It is clear that there are at least a few details that we should add to the current memory model, among them an explicit endorsement of race detectors and a clear statement of how the APIs in sync/atomic synchronize programs. This post restates Go’s overall philosophy and the current memory model and then outlines

GitHub - endojs/Jessie: Tiny subset of JavaScript for ocap-safe universal mobile code
This document is an early draft. Comments appreciated! Thanks. Today, JavaScript is the pervasive representation for (somewhat) safe mobile code. For another representation to achieve universality quickly, it must be a subset of JavaScript, and so runs at least everywhere JavaScript runs. Whereas JSON is a simple universal representation for safe mobile data, Jessie is a simple universal represent

Programming language memory models answer the question of what behaviors parallel programs can rely on to share memory between their threads. For example, consider this program in a C-like language, where both x and done start out zeroed. // Thread 1 // Thread 2 x = 1; while(done == 0) { /* loop */ } done = 1; print(x); The program attempts to send a message in x from thread 1 to thread 2, using d

Range over function types is a new language feature in the Go 1.23 release. This blog post will explain why we are adding this new feature, what exactly it is, and how to use it. Why?

For example, let’s consider this very simple Set type, a generic type implemented on top of a map. // Set holds a set of elements. type
Concurrency is not very intuitive. You need to train your brain to consider what happens when multiple processes execute a certain code block at the same time. There are several issues I often encounter: Failing to recognize potential concurrency issues: It's not uncommon for both beginner and seasoned developers to completely miss a potential concurrency problem. When this happens, and the concur

Python behind the scenes #12: how async/await works in Python
Mark functions as async. Call them with await. All of a sudden, your program becomes asynchronous – it can do useful things while it waits for other things, such as I/O operations, to complete. Code written in the async/await style looks like regular synchronous code but works very differently. To understand how it works, one should be familiar with many non-trivial concepts including concurrency,
The Humble For Loop in Rust By Martijn Faassen • 2024-12-11 • Tags: programming, rust Rust has some really nice functional programming facilities built in, all around an iterator concept. Rust being focused on performance and low level control makes it possible to use this without paying a performance cost. Sometimes I still prefer to use the humble for loop though. In quite a few cases, it combin

Automated tests are important. Without them, programmers waste a huge amount of time manually checking and fixing their code. Unfortunately, many automated tests also waste a huge amount of time. The easy, obvious way to write tests is to make broad tests that are automated versions of manual tests. But they’re flaky and slow. Folks in the know use mocks and spies (I say “mocks” for short in this
