There's a new Linux distro in town for developers...
Fireship • September 24, 2025
This video introduces Omarchy, an opinionated Arch-based Linux distro by David Heinemeier Hansson tailored for developers, showcasing its simple ISO install, default full-disk encryption, Hyperland window manager, preconfigured dev tools and AI coding integrations.
Key Takeaways:
- Omarchy defaults to full-disk encryption during installation and uses Hyperland as its keyboard-focused window manager.
- It bundles developer essentials out of the box—including Git, Docker, Obsidian, Piñata, OBS Studio—and modern shell tools like FZF, ripgrep and custom functions.
- Omarchy provides a preconfigured LazyVim setup for Neovim and lets you install AI coding helpers like Cloud Code via Pac-Man or the Arch User Repository, with Code Rabbit CLI available for in-terminal code reviews.
Inside the $50 Trillion AI Gold Rush | Episode 1
Greg Isenberg • September 24, 2025
Greg Isenberg outlines how AI’s rapid performance gains—now outpacing humans on 95% of tasks—are unleashing a new solo-founder era, and he kicks off Bolt’s record-setting hackathon to empower 100,000 builders to ship AI-driven apps in a single day.
Key Takeaways:
- Greg sold his startup Five Buy to StumbleUpon after meeting its leadership at a PayPal co-founder’s party, which led to his move from Montreal to San Francisco.
- Current AI models outperform humans on 95% of tasks and are improving by 1–2% each month, projected to reach 98% parity within two months.
- Bolt’s global AI hackathon aims to set a Guinness World Record by having over 100,000 participants build and launch AI-powered web apps in just 24 hours.
Enroll in our new course: Building and Evaluating Data Agents
Deeplearning.ai • September 24, 2025
In partnership with Snowflake, Anipam Data and Josh Rainey teach you to build a LingRaph-based data agent with a planner, plan executor, and specialized sub-agents for data retrieval, visualization, and insight generation. You’ll evaluate its outputs and processes using offline metrics and runtime evals, and apply a GPA-inspired framework to log steps, compute metrics, and direct prompt and inline-evaluation fixes to enhance relevance and plan adherence.
Key Takeaways:
- Build a multi-agent data agent in LingRaph with a planner, plan executor, and sub-agents specialized for data retrieval, visualization, and insight generation.
- Evaluate agent performance through offline checks of answer relevance, data grounding, plan soundness, and step adherence, plus runtime evals that provide real-time feedback to redirect the agent.
- Use a GPA framework to log each step, compute evaluation metrics, identify issues, implement targeted prompt and inline evaluation fixes, and validate performance improvements with offline metrics.
Full Tutorial: 20 Tips to Master Claude Code in 35 Minutes (Build a Real App)
Peter Yang • September 24, 2025
Peter Yang demonstrates how to build a family activity finder app using Claude Code, covering 20 concrete tips—from planning in plan mode and drafting specs to integrating Claude’s web search API, debugging with console logs, and managing version control with GitHub.
Key Takeaways:
- Begin every feature by switching Claude Code into plan mode (Shift+Tab) and ask it to explore at least three solution approaches—static DB, third-party APIs, or Claude’s own messages API with web search—before coding.
- Adopt a spec→to-do→code process: have Claude generate a spec.md with requirements, tech stack, design guidelines, and milestones; then a to-do list for each milestone; and only then proceed to code, auditing each output.
- Leverage “/output style explanatory” to get inline explanations of code decisions for learning, use voice dictation tools like Whisper Flow to speed up prompts, and commit each milestone to GitHub for robust version control.
