結婚式のエンドロールを当日作った話
結婚のお礼と報告 でちょこっと書いた結婚式エンドロールをその場で作ってみたのお話 注意事項# 結婚式のエンドロールを自作したりするには結婚式場の協力が必須です。 作り出す前に式場に必ず確認を取りましょう。 PCからそのままプロジェクトにだせばいいじゃん！と思い込むのだめです(自戒) 動機# エンドロールを式場にお願いしようと思ったら高かったので、最近のイケてるサービスとか適当にガッチャンコすれば作れると思った。 今は反省している。 全体の構成# LINE Botに参加者から画像投稿を投げてもらう S3に保存すると同時に投稿者情報をDynamoDBに保存 投稿された画像にDynamoDBの投稿者情報から名前を追記 画像を全部結合して動画化し、事前に生成したエンドロールで必要な部分を結合 式の最後に流してもらう 全体の構成はこんな感じです。 サーバーレスアーキテクチャのお勉強がてら作ろうとした
Firestoreセキュリティルールの基礎と実践 - セキュアな Firebase活用に向けたアプローチを理解する - GMO Flatt Security Blog
こんにちは、株式会社Flatt Security セキュリティエンジニアの梅内(@Sz4rny)です。 本稿では、Cloud Firestore (以下、Firestore) を用いたセキュアなアプリケーション開発を行うためのアプローチについて説明するとともに、そのアプローチを実現するセキュリティルールの記述例を複数取り上げます。 本稿を読むことで、そもそも Firestore とは何か、どのように Firestore に格納するデータの構造を設計、実装すればセキュアな環境を実現しやすいのか、また、Firestore を利用するアプリケーションにおいてどのような脆弱性が埋め込まれやすいのかといったトピックについて理解できるでしょう。 なお、本稿は以前に投稿した記事と共通する部分があります。理解を補強するために、こちらの記事も適宜ご覧ください。 flattsecurity.hatenablo
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

What We Learned from a Year of Building with LLMs (Part I)
It’s an exciting time to build with large language models (LLMs). Over the past year, LLMs have become “good enough” for real-world applications. The pace of improvements in LLMs, coupled with a parade of demos on social media, will fuel an estimated $200B investment in AI by 2025. LLMs are also broadly accessible, allowing everyone, not just ML engineers and scientists, to build intelligence into
Programming is an iterative process - as much as we would like to come up with the perfect solution from the start, it rarely works that way. Good programs often start as quick prototypes. The bad ones stay prototypes, but the best ones evolve into production code. Whether you’re writing games, CLI tools, or designing library APIs, prototyping helps tremendously in finding the best approach before

缶つぶし機とソフトウェア移行技術 - Refactoring to Rust の読書感想文 - じゃあ、おうちで学べる
はじめに ——あるいは、「知っている」と「理解している」の間 Rustのことは、知っていた。学習もしていた。実務でも使っていた。 でも、それは知っているつもりだった。 知ってるつもり 無知の科学 (ハヤカワ文庫NF) 作者:スティーブン スローマン,フィリップ ファーンバック早川書房Amazon 日々Rustで開発し、BoxとRcとArcを使い分け、tokio::spawnでタスクを生成し、?演算子を当たり前のように書いている。FFI？PyO3使えばいいでしょ。WebAssembly？wasm-bindgenがあるじゃない。技術的には、確かに「使える」レベルにはあった。 でも、心のどこかで感じていた違和感があった。 オートバイのエンジンを分解できる人と、エンジンが動く原理を理解している人は違う。コードが動くことと、なぜそう書くべきかを理解することも違う。私は前者だった。メカニックではあった

データバージョンの管理とは？ データバージョンの管理とは、バイナリデータのバージョンを管理することを指します。データバージョンの管理は、Git 等でのコードのバージョン管理をバイナリデータに拡張しています。実験の再現性を高められるメリットがあります。 DVC とは？ データのバージョンを管理する機能をもつオープンソースソフトウェアです。データのハッシュをテキストファイルで保持し git でバージョン管理します。また、yaml ファイルで実行パイプラインを定義して監視対象データが更新された際にハッシュを更新することで、新しいハッシュ値を含んだデータをバージョン管理します。更新されたデータファイルはキャッシュディレクトリに保存され、必要なタイミングで自動的に復元されます。 データのリモートリポジトリを定義することで、データ一式を簡単なコマンド操作で S3 等へ push / pull すること

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. For example, self-driving: It’s easy to demo a car self-driving around a block, but making it into a product takes a decade.”

SemVer in Rust: Tooling, Breakage, and Edge Cases — FOSDEM 2024 Last month, I gave a talk titled "SemVer in Rust: Breakage, Tooling, and Edge Cases" at the FOSDEM 2024 conference.

TL;DR: SemVer is
This paper reflects work done in late 2022 and 2023 to audit for vulnerabilities in terminal emulators, with a focus on open source software.

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

Writing Pythonic Rust
Over the past several weeks I have been attempting to reimplement the API of an existing python library as a wrapper for an equivalent library in Rust. tl;dr: this ended up being much harder than I expected it to be, partly because of important differences in the behaviour of the two languages, and partly because of the (self-imposed) obligation to match an existing (idiomatic) python API. Motivat
Database Fundamentals
About a year ago, I tried thinking which database I should choose for my next project, and came to the realization that I don't really know the differences of databases enough. I went to different database websites and saw mostly marketing and words I don't understand.

The sad state of property-based testing libraries Posted on Jul 2, 2024 Property-based testing is a rare example of academic research that has made it to the mainstream in less than 30 years. Under the slogan “don’t write tests, generate them” property-based testing has gained support from a diverse group of programming language communities. In fact, the Wikipedia page of the original property-bas
Primitive Recursive Functions For A Working Programmer Aug 1, 2024 Programmers on the internet often use “Turing-completeness” terminology. Typically, not being Turing-complete is extolled as a virtue or even a requirement in specific domains. I claim that most such discussions are misinformed — that not being Turing complete doesn’t actually mean what folks want it to mean, and is instead a stand

The state of CI platforms is much stronger than it was just a few years ago.

Centralized CI platforms like GitHub Actions, GitLab Pipelines, and Bitbucket provide benefits of scale, as the Internet serves as a c
"Get or create" is a very common operation for syncing data in the database, but implementing it correctly may be trickier than you may expect.

For a few years now I have been working on the Haskell Language Server (HLS), and the lsp library for the LSP protocol and writing LSP servers. Unsurprisingly, I have developed some opinions about the design of the LSP! Recently I gave a talk about HLS and LSP at the Haskell Ecosystem Workshop at Zurihac 2024. One slide featured a hastily-written table of “LSP: the good, the bad, and the ugly”. As

Setting the Stage Does this sound familar? You make a change to a library to optimize its performance or clean up technical debt or fix a bug, only to get a bug report: some very large, incomprehensibly opaque test is now failing. Or you add a new compiler optimization with a similar result. Now you have a major debugging job in an unfamiliar code base. What if I told you that a magic wand exists
