Running evals on our MCP turned out to be exactly that: performance engineering but for the model's context. Measuring the profiling skill's efficiency and effectiveness has been the real fun these past weeks. 😎 [contains quote post or other embedded content]30 Jun 2026 16:54 +0000at://did:plc:v2xyel3gf52tu44ey4dbnmxv/app.bsky.feed.post/3mpjhq6emxs2phttps://bsky.app/profile/metalmatze.de/post/3mp2gchdur22324 Jun 2026 17:18 +0000at://did:plc:v2xyel3gf52tu44ey4dbnmxv/app.bsky.feed.post/3mp2gchdur223https://bsky.app/profile/metalmatze.de/post/3mkmjesgajk26Forgejo has been building federation so I can use my instance to talk to your instance to work on software together.

Just exec into the container and run commands directly. SQL in cockroach, wget the Prometheus HTTP API, same for Jaeger. 😏18 Mar 2026 11:14 +0000at://did:plc:v2xyel3gf52tu44ey4dbnmxv/app.bsky.feed.post/3mhdebz22vk2q
