I Found Jesus at a Drone Show

Drone shows are the new fireworks—and possibly a new kind of religion. I traveled to Texas to be converted.

The war against ‘woke’ could end US science as we know it

A sneaky rule change has the potential to blow up scientific research in the United States. But there's still time to fight it. On May 29th, the Office of Management and Budget (OMB) issued a 412-page proposal to revise federal financial assistance. The language is a combination of distinctly Trumpian attacks on "woke" policies and […]

Comcast is splitting in two

Comcast has announced plans to separate itself into two publicly traded companies, spinning off its NBCUniversal and Sky broadcasting arms. The shake up aims to protect the media conglomerate's profitable broadband and wireless brand, which will retain the "Comcast" company name, as its media and entertainment business - now collectively named "NBCUniversal" - faces increasing […]

Wiring an LLM Agent to Live Crypto Market Data over MCP

Why candles aren't enough, what microstructure your agent actually needs, and how a keyless self-describing MCP schema beats hardcoded REST parsing in an agent loop. If you've ever pointed an LLM agent at a crypto market and asked it "is something happening on SOL right now?", you've probably watched it fetch a candle endpoint, see green bars, and confidently say "yes, bullish momentum." Then the move reverses in ninety seconds and the agent has no idea why. I build trading-adjacent agent...

CacheWeaver Reorders RAG Evidence for Prefix-Cache Reuse: Prefix-Cache-Aware Evidence Reordering

What: On June 18, 2026 , researchers posted CacheWeaver — a prompt-layer method built on prefix-cache-aware evidence reordering . It changes only the order retrieved RAG chunks appear in the prompt, so the serving engine can reuse more of its KV prefix cache . Why: In retrieval-augmented serving, time-to-first-token is dominated by prefilling the evidence ; reusing a cached prefix skips that work, and CacheWeaver squeezes out the reuse a naive system leaves on the table — with no ...

React Suspense & the use() Hook: Complete Guide (2026)

Suspense has been in React since 16.6, but data fetching with Suspense was experimental until React 18/19. Now it's a first-class async UI primitive, and the new use() hook gives you a direct way to integrate it without a library. What Suspense Actually Does Suspense doesn't know anything about fetching. When a component throws a Promise during render, React catches it, renders the nearest <Suspense> boundary's fallback, and retries when the Promise resolves. /...

AI Agents Are Rewriting the Rules of Web Traffic – And Most Businesses Aren’t Ready

Nearly half of internet traffic is no longer human For years, web security teams have focused on a familiar set of threats: DDoS attacks, credential stuffing, scraping bots, and malicious automation. But a new category of traffic is emerging — one that doesn't necessarily look malicious, yet can have many of the same operational consequences. AI agents. Powered by large language models and autonomous workflows, these systems increasingly browse websites, compare products, retrieve i...

The Python exception that leaked tenant secrets

I was lying in my four-year-old's bed at 8:30 PM (long story, Spider-Man was involved) when a Slack message came in: yoo, we're logging all tenant config secrets in plain text in prod Not dev. Not staging. Production. Tenant config. Plain text. The line that surfaced it was raise e . But switching that to bare raise would not have prevented the incident. The secret was already baked into the exception message string before the raise happened. raise e was the symptom. The actual...

Ford Called Them Back, AI Is Now the #1 Layoff Reason, and GPT-5.6 Sol Is Government-Gated — AI News Jun 29

Three AI moves hitting your workforce, your factory floor, and your API access: ① AI is now the #1 reason companies give for layoffs 267 layoff events in 2026. 185,894 workers cut — that's 1,044 jobs disappearing every single day. 56pct of those events explicitly cite AI, automation, or machine learning as a contributing factor (150 events, 156,270 workers). Oracle alone cut 30,000 people — not because of financial weakness, but to reallocate toward AI infrastructure. Entry-level softw...

How I Built a Real-Time Audio Visualizer with the Web Audio API

What is a browser-based audio visualizer? A browser-based audio visualizer is a real-time graphical display that converts live audio signals into visual patterns — waveforms, frequency spectrums, or spectrograms — using the Web Audio API and HTML5 Canvas , entirely on the client side with zero server processing. I built Octaveview , a free, professional-grade online tone generator that includes four visualization modes: Waveform (Oscilloscope) , Spectrum Analyzer , Dual View , and ...

The Model Does Not Need Memory. The Situation Does.

I think I was asking the wrong question. For a while, the question was simple: does memory make agents smarter? It sounds like the right question. It is also a trap, because it assumes that memory should be judged as a generic intelligence booster. You add a memory layer, the agent remembers more things, and somehow the output should become better. More complete. More accurate. More human. More whatever word we are currently using to avoid saying “I hope this expensive thing works.” A...

I Built an AI-Powered Database Schema Explorer for the H0 Hackathon

The following content was created for the purposes of entering the H0 Hackathon. #H0Hackathon You join a new project. The database has 30 tables. No documentation. No ERD. No one remembers why status_v2_legacy exists. Existing tools force a tradeoff. pgAdmin gives raw access but no visualization. dbdiagram.io lets you draw schemas but requires manual input that goes stale after every migration. SchemaSpy needs CLI setup and Java. DBeaver is desktop-only — you can't share a link with ...
