Watch First#

Scaling Uber with Thuan Pham (Uber’s first CTO) is an incredibly substantive, hype-free breakdown of surviving engineering hypergrowth. It provides a rare inside look at how Uber was forced into a microservices architecture not out of design purity, but purely to survive scale before their NodeJS dispatch monolith hit a hard computational brick wall.

Developer Tools & Platforms#

Create and install an F1 inspired MCP Server in VS Code by the Visual Studio Code channel offers a practical, code-heavy tutorial on building a Model Context Protocol (MCP) server from scratch. It uses fastmcp in Python to expose a local SQLite database to GitHub Copilot chat, effectively demonstrating how to give AI agents secure access to your internal tooling. Migrating Legacy Code Just Got Easier by Syntax provides a highly pragmatic guide for using LLMs to migrate a decade-old Express/Pug monolith to Hono and JSX. Instead of letting the AI hallucinate architectural changes, the hosts stress establishing strict manual patterns first—like adopting AsyncLocalStorage for standardized web requests—and using the LLM strictly to generate exhaustive test checklists and perform deterministic syntax translation.

AI & Machine Learning#

AI Research Breakthroughs from NVIDIA Research from NVIDIA Developer is a dense and highly technical panel covering genuine frontiers in AI. Key highlights include Yejin Choi discussing Reinforcement Learning as Pre-training (RLP) to force models to explicitly reason before token prediction, Marco Pavone on the Alpamayo-1 vision-language-action model using post-training alignment to sync explicit chain-of-thought traces with physical AV actions, and zero-shot sim-to-real transfer for robotics using Neural Robot Dynamics (NeRD). Additionally, a brief customer spotlight What Codex Unlocks for Ramp by OpenAI is mostly marketing, but notable because it explicitly mentions Ramp is already running Codex with “GPT 5.4” in production for automated PR reviews and an on-call assistant agent.

Everything Else#

For engineering leadership, the second half of the Scaling Uber video delivers excellent lessons on crisis management and cross-functional structuring, including how they navigated an impossible five-month deadline to rebuild their entire stack locally for the China launch. Finally, be aware of the date: Tragic mistake… Anthropic leaks Claude’s source code by Fireship and The Ultimate Minimal Phone by Marques Brownlee are both April Fools’ Day videos. The former analyzes a fake 500k-line leak containing “undercover mode” and a “regex frustration detector,” while the latter is a serious-sounding review of a $10 VTech Bluey children’s toy.
