Hands-on review of DJI Pocket 3 praising its portability and instant operation, but finding the video quality disappointing compared to iPhone 15 ProRes due to aggressive compression.

Envisioning an AI knowledge engine that records conversations, extracts insights, and surfaces relevant knowledge when needed. Three key challenges: data collection, knowledge extraction, and real-time participation.

Technical lessons from building an AI video transcription tool: YouTube OAuth2 authentication, async task-based APIs, Python concurrency patterns, GPT laziness issues, and iOS Shortcuts integration.

Videos are terrible for learning—can't skim, search, or navigate easily. Yet creators make millions because video makes the "author" tangible, lowering the barrier to payment. Articles hide the author behind ideas.

Argues that effective AI-assisted programming shifts focus from data structures and algorithms to writing detailed comments and DocStrings. Draws parallels between managing AI and managing human teams, emphasizing delegation, context provision, and quality checks.

Compares three approaches to writing a course introduction—fully AI, AI-assisted, and fully human. Reveals that human writing conveys tension and engagement that AI's diplomatic, detached style lacks, and choosing not to use AI can itself show respect to users.

A practical guide to prompt engineering: matching tasks to LLM capabilities, managing context windows, using web search for reliability, and leveraging agents for domains like math and robotics.

Observes that AI elevates programming from last resort to first-class problem-solving method and enables personalized, hands-on learning. Argues AI's impact on IT is democratization of programming and transformation of how we acquire technical skills.

Documents an experiment connecting AI to astrophotography robotics. Explores the security-flexibility tradeoff, using Python with class encapsulation, AST parsing, and sandboxing to safely let AI control telescope equipment while preventing malicious code execution.

A two-week deep dive into Apple Vision Pro reveals it's fundamentally a VR device, not AR. Excels at hands-free scenarios like lying down, exercising, or multitasking with multiple windows, but falls short for office work and VR viewing due to limitations in text density and format support.
