防衛省サイバーコンテスト 2025 writeup - st98 の日記帳 - コピー
2/2に12時間というちょうどよい競技時間で開催された。21時終了だったけれども、11時45分ぐらいに最速で全完して1位🎉 第1回以来4年ぶりの優勝だ。昨年大会の第4回ではヒントの閲覧数で優勝を逃してしまって悔しい思いをしたので、雪辱を果たすことができ嬉しい。開始直後からずっと1位を独走できており、450名以上のプレイヤーがいる中で圧勝だったのも嬉しい。 昨年度や一昨年度はバルクが作問を担当していたが、今回はAGESTが担当していた。これまでの問題と比較すると全体的に易化したように思うが、解くにあたって発想の大きな飛躍を必要とするいわゆる「エスパー要素」のある問題はごく一部を除いて存在しておらず*1、よかったと思う。また、昨年度・一昨年度に引き続きwriteupは公開可能というのもよかった。 戦略というほどの戦略は立てていなかったけれども、とりあえずWebを見た後は全カテゴリを上から見て

優秀と噂なCohere社のCommand R+でRAGチャットボットを簡単に構築して体験しよう！ - Qiita
1. はじめに Cohere社が最近リリースしたLLMのCommand R+がGPT4に迫る性能を発揮していたり、RAG利用での性能で話題となっています。 そのCommand R+でRAGを体験できるチャットアプリの実装がLightningAIにてチュートリアルが公開されています。 これを身近な環境で動かしてみたいと思います。 このチャットボットでCohere社の以下のモデルが使われています LLM: Command R+ Embed: embed-english-v3.0 / embed-multilingual-v3.0 Reranker: rerank-english-v3.0 / rerank-multilingual-v3.0 以下の動画のようにブラウザでPDFファイルをアップロードしてチャットで問い合わせができます。 2. 必要なもの 以下の2つを準備しましょう。 Cohere
Developers are increasingly relying on AI coding assistants to accelerate our daily workflows. These tools can autocomplete functions, suggest bug fixes, and even generate entire modules or MVPs. Yet, as many of us have learned, the quality of the AI’s output depends largely on the quality of the prompt you provide. In other words, prompt engineering has become an essential skill.

型安全かつシンプルなAgentフレームワーク「PydanticAI」の実装を解剖する - ABEJA Tech Blog
はじめに こちらはABEJAアドベントカレンダー2024 12日目の記事です。 こんにちは、ABEJAでデータサイエンティストをしている坂元です。最近はLLMでアプローチしようとしていたことがよくよく検証してみるとLLMでは難しいことが分かり急遽CVのあらゆるモデルとレガシーな画像処理をこれでもかというくらい詰め込んだパイプラインを実装することになった案件を経験して、LLMでは難しそうなことをLLM以外のアプローチでこなせるだけの引き出しとスキルはDSとしてやはり身に付けておくべきだなと思うなどしています（LLMにやらせようとしていることは大抵難しいことなので切り替えはそこそこ大変）。 とはいうものの、Agentの普及によってより複雑かつ高度な推論も出来るようになってきています。弊社の社内外のプロジェクト状況を見ていても最近では単純なRAG案件は減りつつあり、計画からアクションの実行、結果

Rust is an appealing language for building user interfaces for a variety of reasons, especially the promise of delivering both performance and safety. However, finding a good architecture is challenging. Architectures that work well in other languages generally don’t adapt well to Rust, mostly because they rely on shared mutable state and that is not idiomatic Rust, to put it mildly. It is sometim

Building the fastest Lua interpreter.. automatically!
This is Part 1 of a series of posts. Part 2 is available here: Building a baseline JIT for Lua automatically It is well-known that writing a good VM for a dynamic language is never an easy job. High-performance interpreters, such as the JavaScript interpreter in Safari, or the Lua interpreter in LuaJIT, are often hand-coded in assembly. If you want a JIT compiler for better performance, well, you’
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.

How a simple Linux kernel memory corruption bug can lead to complete system compromise
In this case, reallocating the object as one of those three types didn't seem to me like a nice way forward (although it should be possible to exploit this somehow with some effort, e.g. by using count.counter to corrupt the buf field of seq_file). Also, some systems might be using the slab_nomerge kernel command line flag, which disables this merging behavior. Another approach that I didn't look

PySkyWiFi: completely free, unbelievably stupid wi-fi on long-haul flights | Robert Heaton

The network login page demanded credit card details. I fumbled for my card, which I eventually discovered had hidden itself inside my passport. As I searched I noticed that the login page was encouraging me
