これは matten を紹介する全 4 回シリーズの第 3 回です。前回は数値計算のコア部分を紹介しました。今回は雑然とした実世界のデータを取り込むしくみについてです。 課題事項 前回紹介した Tensor （数値テンソル）は、つくられた時点からクリーンです。すべてのセ
I ran 200 paper trades. Win rate was 91%. P&L tracker showed positive every session. I moved to live. First week looked fine. Then I pulled the actual
This is the third of four short posts about matten. The previous post covered the numeric core. This one covers a separate feature: ingesting messy, r
I stared at CpiContext::new(...) for a solid ten minutes on Day 71. I knew the arguments existed. I had no idea what they meant. I copied working cod
I can't stand the SSH clients on the market anymore. Every tool wants to grab a piece of my home, take a piss without flushing. They maintain their
I was watching YouTube videos to see what tools everyone else was using. There are a lot of good AI applications out there and I tried most of them.
LiteLLM is the glue a lot of us reach for when an app has to talk to more than one model provider. One interface, dozens of backends. It is great. But
A practical comparison of local-first and cloud-based password managers for small and medium businesses, with a focus on data sovereignty and complian
TL;DR We're a small ML lab building alpha models for a handful of partners. Our market simulation loop — the part that keeps you honest abo
Claude 5 is here. Every timeline is full of benchmark charts. SWE-bench scores. Coding comparisons. Context windows. Token pricing. But after b
Você já usou o GPT, mas sabe o que existe dentro dele? Neste post vamos construir em Rust o bloco mais fundamental de qualquer rede neural, um único n
Most "agent memory" and "agent context" tools today require sending your data to someone else's cloud. If you operate in a regulated, air-gapped, or s
TL;DR — A Kafka + Flink + OTel ingestion pipeline cost us ~$700–800/month at 10 MB/s. We rebuilt it as a single binary where the data, the write-ahea
Introduction We've all been there. You're working on a technical project, everything is beautifully version-controled in Git and then comes
When we look back at the 1990s, our collective cultural memory betrays us. We retroactively paint the decade as an era of primitive digital toys—a neo
Local coding models are everywhere right now, and benchmark numbers on a README tell you almost nothing useful. Does the model loop? Does it hallucina
Project Code：https://github.com/euv-dev/euv euv provides powerful primitives for managing CSS dynamically at runtime. The css-vars! and var! macros
Most AI agents fail in a very boring way. Not because they are stupid. Not because the model is weak. Not because the prompt is bad. They fail becau

When I first saw this in Rust: fn applyF: Fn()>(f: F) { f(); } I thought — okay, Fn, fine. Then I saw FnMut. Then FnOnce. And I had no
