大実験！ChatGPTは競プロの問題を解けるのか (2024年5月版) - E869120's Blog
1. はじめに 2024 年 5 月 14 日、OpenAI 社から新たな生成 AI「GPT-4o」が発表され、世界に大きな衝撃を与えました。これまでの GPT-4 よりも性能を向上させただけでなく1、音声や画像のリアルタイム処理も実現し、さらに応答速度が大幅に速くなりました。「ついにシンギュラリティが来てしまったか」「まるで SF の世界を生きているような感覚だ」という感想も見受けられました。 しかし、いくら生成 AI とはいえ、競技プログラミングの問題を解くのは非常に難しいです。なぜなら競技プログラミングでは、問題文を理解する能力、プログラムを実装する能力だけでなく、より速く答えを求められる解法 (アルゴリズム) を考える能力も要求されるからです。もし ChatGPT が競技プログラミングを出来るようになれば他のあらゆるタスクをこなせるだろう、と考える人もいます。 それでは、現代最強の

REST API Design Best Practices Handbook – How to Build a REST API with JavaScript, Node.js, and Express.js
By Jean-Marc Möckel I've created and consumed many API's over the past few years. During that time, I've come across good and bad practices and have experienced nasty situations when consuming and building API's. But there also have been great moments. There are helpful articles online which present many best practices, but many of them lack some practicality in my opinion. Knowing the theory with

How modern browsers work
Note: For those eager to dive deep into how browsers work, an excellent resource is Browser Engineering by Pavel Panchekha and Chris Harrelson (available at browser.engineering). Please do check it out. This article is an overview of how browsers work. Web developers often treat the browser as a black box that magically transforms HTML, CSS, and JavaScript into interactive web applications. In tru
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

Today we’re excited to announce the availability of TypeScript 4.7! If you’re not yet familiar with TypeScript, it’s a language that builds on JavaScript and adds syntax for types. Types help describe what kinds of values you’re working with and what kinds of functions you’re calling. TypeScript can use this information to help you avoid about mistakes like typos, missing arguments, or forgetting
Today we are excited to announce the beta release of TypeScript 4.7! To get started using the beta, you can use npm with the following command: npm install typescript@beta You can also get editor support by Downloading for Visual Studio 2022/2019 Following directions for Visual Studio Code and Sublime Text 3. Here’s a quick list of what’s new in TypeScript 4.7! ECMAScript Module Support in Node.js
Go 1.21 includes new features to improve compatibility. Before you stop reading, I know that sounds boring. But boring can be good. Back in the early days of Go 1, Go was exciting and full of surprises. Each week we cut a new snapshot release and everyone got to roll the dice to see what we’d changed and how their programs would break. We released Go 1 and its compatibility promise to remove the e
I've found that one of the best ways to understand a new concept is to start from the very beginning. Start from a place where it doesn't exist yet and recreate it yourself, learning in the process not just how it works, but why it was designed the way it was. This isn't a practical guide to async, but hopefully some of the background knowledge it covers will help you think about asynchronous prob

New CSS length authoring tools DevTools added an easier yet flexible way to update lengths in CSS! In the Styles pane, look for any CSS property with length (e.g. height, padding). Hover over the unit type, and notice the unit type is underlined. Click on it to select a unit type from the dropdown. Hover over the unit value, and your mouse pointer is changed to horizontal cursor. Drag horizontally
TL;DR; We are changing std::sort in LLVM’s libcxx. That’s a long story of what it took us to get there and all possible consequences, bugs you might encounter with examples from open source. We provide some benchmarks, perspective, why we did this in the first place and what it cost us with exciting ideas from Hyrum’s Law to reinforcement learning. All changes went into open source and thus I can
Text2Landscape: Visualize a Text in Multiple Spaces with R — Force-directed networks, Biofabric, Word Embeddings, Principal Component Analysis and Self-Organizing Maps
First Visualizations: Frequencies Let us first visualize word frequencies. We can get these frequencies with the quanteda package, which implies transforming the column of lemmas (text.lemmas$lemma) into a quanteda tokens object, then to a document-feature matrix. Doing so, we only retain significant parts of phrases (nous, proper nouns, verbs and adjectives). This only partially spares us the tas

No trial. No credit card required. Just your GitHub account. Several weeks ago, the .NET Blog featured a post What is .NET, and why should you choose it?.

This post is the first such follow-up, deep-diving into the history leading to, the d
I was recently made maintainer of the json gem, and aside from fixing some old bugs, I focused quite a bit on its performance, so that it is now the fastest JSON parser and generator for Ruby on most benchmarks. Contrary to what one might think, there wasn’t any black magic or deep knowledge involved. Most of the performance patches I applied were fairly simple optimizations driven by profiling. A

Hey… quick question, why are anime catgirls blocking my access to the Linux kernel?

The project “weighs the souls” of HTTP requests to help protect the web from AI crawlers. If you’ve seen anime catgirl avatars when visiting a new website, that’s Anubis. A website bloc
Typeclass metaprogramming is a powerful technique available to Haskell programmers to automatically generate term-level code from static type information. It has been used to great effect in several popular Haskell libraries (such as the servant ecosystem), and it is the core mechanism used to implement generic programming via GHC generics. Despite this, remarkably little material exists that expl
