はじめに大規模言語モデルであるChatGPTに文章を渡す際、適切な区切り線の使用は、情報の正確な伝達や解釈に大いに役立ちます。 この記事では、区切り線に適切なものを検証します。 区切り線とは？使い方区切り線は文章を区切る時に使用する文字列のことです。 例えば下記のようなものです。 また、使い方をまとめた記事もあるので参考にしてください。 def test() a = "a" b = "b" c = a + b print(c) ================================ ←これが区切り線 上記のコードについて教えてください 結論先に結論を言うと、4個～16個連続した「-」か「=」 もしくは8の倍数の「-」か「=」が区切り線としてはベストでした。 ---- ---------------- -------------------------------- ==== ==

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

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
copilot-explorer
Copilot Internals | thakkarparth007.github.io Github Copilot has been incredibly useful to me. It can often magically read my mind and make useful suggestions. The thing that surprised me the most was its ability to correctly “guess” functions/variables from surrounding code – including from other files. This can only happen, if the copilot extension sends valuable information from surrounding cod
Preliminaries What Is xargs? It's an adapter between text streams and argv arrays, two essential concepts in shell. You pass it flags that specify how to split stdin. Then it generates arguments and invokes processes. Example: $ echo 'alice bob' | xargs -n 1 -- echo hi hi alice hi bob What's happening here? xargs splits the input stream on whitespace, producing 2 arguments, alice and bob. We passe

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

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!
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

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

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.
