Candidates are expected to be established DEV members with experience running Discord communities, and the package includes a competitive salary, stock options, health and retirement benefits, unlimited PTO, and travel opportunities.

osFoundry's Memory and Knowledge Base keep AI-learned facts and return them as context

osFoundry bundles Notes, Knowledge Base, Memory, Lessons, Chat History and Indexed Folders to stop coding agents from forgetting project details between sessions. In the desktop app, each store has its own screen, and a toggle on each controls whether the AI may read it. The Memory screen shows what each agent knows, such as database versions and test commands, and separately lists lessons written only after a reviewer rejected work or a step failed. Users can export or import memories and lessons to a file, since they stay on the device and do not move automatically between machines. A user can also index a repository locally with on-device embeddings, which lets the agent search code by meaning and return exact file paths and line ranges.

Building Audit Logs in Phoenix Without Exposing Passwords

A developer building audit logging for a Phoenix application found that a basic Ecto-based approach had several flaws. Application-level logging can omit sensitive fields like passwords by filtering virtual fields and associations, but it misses changes made outside the changeset path, such as bulk updates or manual database edits. To capture every modification regardless of how it happened, the author turns to PostgreSQL row-level triggers, which fire on every insert, update, and delete. The trigger approach can record old and new values while excluding secrets such as hashed passwords. The article argues that database-level capture is necessary for a reliable audit trail.

Why an 89% hallucination rate needs context: what the benchmark actually measures

A developer published a video walkthrough to explain the 89% hallucination figure, which is often cited as proof that AI models fabricate information constantly. The figure comes from a specific evaluation setup, including a defined prompt set, sampling method, and a scoring rubric that counts confident fabrication rather than hedging. The author notes that two runs with slightly different random seeds shifted the result by several points. The rubric distinguishes unsupported claims from factually wrong ones, which means a correct answer that the evaluation cannot verify can still be scored as a hit. The author also describes the cost of running the evaluation, including about 40 minutes of compute, hundreds of thousands of judging tokens, and substantial manual human review to check the rubric.
