Ollaya downloads and serves open decision models on your own machine. Typed, calibrated answers in milliseconds, private and open source.

Effort tells your model how many resources to spend on a task. When to turn it down, when to turn it up, and why the default is the right place to start.

What effort really is and when to use which level in Claude Code, from my own tests of three builds and a deep dive into Terminal-Bench 3.0 on Opus 5.5 and Fable 5.1.

An alternative logical projection of React with 100% API compliancy but simpler implementation resulting in smaller bundle size and better performance. - TanStack/redact

How we fully migrated github.com away from CSS-in-JS.

In seven months, the skills.sh registry grew to 1 million agent skills with nearly 280 million installs. This report uses aggregate data from that registry to examine what people teach agents, what gets installed, and what lasts.

OpenAIのドキュメントをもとにAgentの基本構成を整理し、OpenAI Agents SDKとClaude Agent SDKの違いを比較したうえで、Goで最小のAgentを実装します。

はじめに こんにちは。プラットフォームエンジニアリングチームに所属している徳富(@yannKazu1)です。 MySQL が遅いとき、まず EXPLAIN で計画を見る。見積もりが怪しければ EXPLAIN ANALYZE で実測と突き合わせる。たいていのケースはこの二つで十分で、実際自分もそれで困ったことはほとんどあ…

A malicious Firefox extension fetches its payload after installation to evade detection, steal Google session cookies, and automate account takeover.

If you run a platform with a dozen or more services behind it, you’ve probably seen this pattern. Service A checks an API key. Service B calls out to your identity provider directly. Service C has a half-finished authentication middleware that hasn’t been touched in a while. Every team solved the same problem differently, and […]

Worker Previews gives every branch its own URL, configuration, state, and observability, so you and your agents can test changes in parallel without affecting production.

Lovable’s OJ rewrites Vite’s dev server in Rust, reducing memory use and preview times as AI lowers the cost of open source reimplementation.

Klaviyo built an internal app platform on Vercel and opened it to the whole company. See how 512 employees shipped 356 apps in two weeks, how Secure Compute keeps every app on Klaviyo's own databases, and how an idea goes live in 3 minutes.

Before the latest release, NGINX had to be controlled exclusively by Unix signals. The most notable one is SIGHUP or the well-known “nginx -s reload” command. This configuration method, while very stable, does not meet modern environment requirements: there are very few available options, no direct feedback messages on errors, and no real extensibility. We […]

A complete reference to the tools and full skill definitions available in this Codex Work session.

Inside our performance sprint: the benchmarks Claude built, the loop each Slack thread ran, and the guardrails that let us ship 3,000 changes safely.

A long time ago I ran a write-heavy system on a hub and a handful of workers. Each worker took a share of the application traffic and wrote events locally. The …

A detailed explanation of Postgres deletions and how to avoid poor deletion and garbage collection performance.

What SELECT FOR UPDATE, FOR SHARE, and a foreign key check actually write into the tuple header. t_xmax as a locker, the infomask bits that say so, MultiXactIds when two sessions lock the same row, and the pg_multixact files that grow behind them.

Not-so-simple PostgreSQL sharding using partitioning, logical replication and foreign data wrappers - mkleczek/pgwrh

In this blog post, we’ll compare pgBackRest’s compression algorithms and levels to find where spending more CPU stops buying a meaningfully smaller backup. The short version of the answer, which we’ll build up to with real numbers, is that Zstandard at a low level is the sweet spot, and its default (zst(3)) already sits right … Continued
