        World’s First MIDI Shellcode Jan 2025 · 45 min read I gained remote code execution via MIDI messages to trick my synth into playing Bad Apple on its LCD. This blog post is about my journey with this reverse engineering project. Final iteration of Bad Apple The beginning I’ve had this Yamaha PSR-E433 synth for a very long time, and a couple of years ago I decided to open it up — partly because it w

          以下の記事が面白かったので、簡単にまとめました。 ・Introducing Structured Outputs in the API 1. Structured Outputs昨年のDevDayで、「JSONモード」を導入しました。これは、OpenAIのモデルを使用して信頼性の高いアプリを構築しようとしている開発者にとって便利な構成要素です。「JSONモード」は、有効なJSON出力を生成するためのモデルの信頼性を向上させますが、モデルの応答が特定のスキーマに準拠することを保証するものではありません。本日、APIに「Structured Outputs」を導入します。これは、モデルによって生成された出力が、開発者が提供するJSONスキーマと完全に一致するように設計された新機能です。 複雑なJSONスキーマのフォローの評価では、「Structured Outputs」を備えた新しいモデル「g

If this target is provided by LLVM, LLVM may have the target as an experimental target, which means that you need to use Zig-provided binaries for the target to be available, or build LLVM from source with special configure flags. zig targets will display the target if it is available.

              It is December. That means annoying Christmas things are everywhere, including but not limited to the annual programming semi-competition known as Advent of Code. The problem with Advent of Code is that it is a waste of time. Most of the puzzles are in the realm of either string processing (somewhat applicable to programming), logic puzzles (not really applicable to most programming), or stupid go

                • A 2025 Survey of Rust GUI Libraries

                  I did this in 2020 and then again in 2021, but I’m in the mood to look around again. Let’s look through Are We GUI Yet? and see what’s up these days. The task today is to have a text label and an input field that can change the text in the label. In React, for example, this is basically free: const Demo = () => { let [state, setState] = useState("Hello, world!"); return ( <div> <p>{state}</p> <inp

                      I find blockchain fascinating because it extends open source software development to open source + state. This seems to be a genuine/exciting innovation in computing paradigms; We don’t just get to share code, we get to share a running computer, and anyone anywhere can use it in an open and permissionless manner. The seeds of this revolution arguably began with Bitcoin, so I became curious to dril
