Three weeks into testing, a learner told me my AI tutor gave her the wrong answer.
Not obviously wrong — just outdated enough to mislead.
That was the moment I realized something most RAG systems quietly ignore: they have no sense of time. My system retrieved the most similar document, not the most current one. And in a knowledge base that changes constantly, that’s a serious flaw.
The fix wasn’t in the retriever or the model. It was in the gap between them.
I built a temporal layer that filters expired facts, boosts time-sensitive signals, and makes the system prefer what’s still true — not just what matches.

When OpenAI was busy experimenting with AI-powered gaming bots, Microsoft CEO Satya Nadella and OpenAI CEO Sam Altman were in the early days of forming an AI partnership. Court documents from the ongoing Musk v. Altman trial have provided a rare look at the communications between Microsoft's top executives about investing in OpenAI and fears the AI startup could "storm off to Amazon" and "shit-talk" Microsoft.
Just days after OpenAI showed a bot beating a Dota 2 professional in the summer of 2017, Altman responded to Nadella's congratulations email with a proposal for a much bigger partnership with OpenAI to fund its next phase of AI resear …

It’s harder than it might seem to create a stand-alone Python app. It’s also harder than you might think to reliably back up SQLite databases, but Python has the tools for it. And while it’s not easy to install Python on an air-gapped machine, it absolutely can be done.

Why it’s so hard to create stand-alone Python apps
Python’s dynamism is one of its most powerful features. It’s also why making stand-alone apps from Python programs is such a bear.
How to back up SQLite databases the right way (not by copying them!)
SQLite databases are single files, so backing them up just means copying them, right? Wrong. Make backups the proper way by using SQLite’s own backup mechanisms.
Python’s new frozendict type, demonstrated
A long-desired and -debated core addition to the language: a “frozen” or immutable dictionary, is coming in Python 3.15. See where it’ll be most useful in our live demo.

In this tutorial, we explore CloakBrowser, a Python-friendly browser automation tool that uses Playwright-style APIs within a stealth Chromium environment. We begin by setting up CloakBrowser, preparing the required browser binary, and resolving the common Colab asyncio loop issue by running the sync browser workflow in a separate worker thread. We then move through practical […]

RAG is a model that connects large language models to live agency knowledge bases — enabling grounded, mission-specific responses, rather than generic outputs.
