Michael #1: httptap Rich-powered CLI that breaks each HTTP request into DNS, connect, TLS, wait, and transfer phases with waterfall timelines, compact summaries, or metrics-only output.Features Phase-by-phase timing – precise measurements built from httpcore trace hooks (with sane fallbacks when metal-level data is unavailable).All HTTP methods – GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS with request body support.Request body support – send JSON, XML, or any data inline or from file with automatic Content-Type detection.IPv4/IPv6 aware – the resolver and TLS inspector report both the address and its family.TLS insights – certificate CN, expiry countdown, cipher suite, and protocol version are captured automatically.Multiple output modes – rich waterfall view, compact single-line summaries, or -metrics-only for scripting.JSON export – persist full step data (including redirect chains) for later processing.Extensible – clean Protocol interfaces for DNS, TLS, timing, visualization, and export so you can plug in custom behavior.Example: Brian #2: 10 Smart Performance Hacks For Faster Python Code Dido GrigorovA few from the list Use math functions instead of operatorsAvoid exception handling in hot loopsUse itertools for combinatorial operations - huge speedupUse bisect for sorted list operations - huge speedup Michael #3: FastRTC The Real-Time Communication Library for Python: Turn any python function into a real-time audio and video stream over WebRTC or WebSockets.Features 🗣️ Automatic Voice Detection and Turn Taking built-in, only worry about the logic for responding to the user.💻 Automatic UI - Use the .ui.launch() method to launch the webRTC-enabled built-in Gradio UI.🔌 Automatic WebRTC Support - Use the .mount(app) method to mount the stream on a FastAPI app and get a webRTC endpoint for your own frontend!⚡️ Websocket Support - Use the .mount(app) method to mount the stream on a FastAPI app and get a websocket endpoint for your own frontend!📞 Automatic Telephone Support - Use the fastphone() method of the stream to launch the application and get a free temporary phone number!🤖 Completely customizable backend - A Stream can easily be mounted on a FastAPI app so you can easily extend it to fit your production application. See the Talk To Claude demo for an example of how to serve a custom JS frontend. Brian #4: Explore Python dependencies with pipdeptree and uv pip tree Suggested by Nicholas Carsner We have covered it, but in 2017 on episode 17.pipdeptree Use pipdeptree --python auto to allow it to read your venvuv pip tree Also check out uv pip tree and some useful flags --show-version-specifiers to show the rules--outdated notes packages that need updated Extras Brian: Lean TDD 0.1.1 includes an updated intro and another chapter, “Essential Components”VSCode Peacock Extension - color code your different projects Joke: Sure Grandma
