My AI Agents Were Talking Past Each Other in Our Team Chat. So They Got a Protocol.

A team member replied to a message my AI agent posted in our team chat. A different AI agent answered them. It had absolutely no idea what they were talking about. Here's the setup: my homelab runs a small fleet of agents. Claude Code sessions on my Mac do the heavy lifting. A WhatsApp bot — a Python wrapper that spawns a fresh Claude process per message — lives in a "Claude helper" group chat wi...

Extreme UI/UX — Through the Lens of a Calculator

"This certifies that *$10,000** deposited at 4.35% APY shall mature to $10,443.78."* That's not the result box. That is the calculator. I built a CD rate calculator at cdratecalc.com. Minimal feature set — maybe an afternoon of work. This post isn't about features. It's about the design decisions behind them: which metaphor to commit to, which motion belongs where, and how to verify that the ...

Why Even Advanced AI Breaks Stock Registers: 12 Years of Snapshot Log Evolution and RDBMS Physics

stock balances is a minefield**. In SQL textbooks, everything looks clean: run SUM(quantity) over transaction history or use a ROW_NUMBER() window function — done. But as soon as the system grows to millions of rows, these "pretty" academic solutions turn the RDBMS into a sluggish bottleneck. And when real business scenarios appear (negative sales, backdated documents, on-the-fly manufacturing), ...

The 4 Notification Categories Users Actually Whitelist (Based on 60 App Interviews)

Users whitelist only four notification categories: someone they know did something involving them, a thing they explicitly set up, a transaction they're expecting, and a time-critical alert from a system they trust. Everything else — feature announcements, recommendations, streaks, re-engagement, promos — gets muted within two weeks. Users pattern-match to category, not copy. Better push copy opt...

Fast at Lunch. Slow at Scale: Why Your App Gets Slow When Real Data Arrives

A page that feels instant with a few users can become painfully slow when your business grows. The code hasn’t changed. The server hasn’t changed. The database hasn’t suddenly become bad. The difference is scale. More users. More records. More requests. More data moving through the same code paths. Most performance problems don’t appear when you build the feature.

Is it possible to make the transition from 270deg to 360deg be to 0deg without rotating counter clockwise?

How can this be made to rotate around back to zero degrees within one full turn rather than mutliples of 360? If set to zero rather than 360, the rotation is three turns counter clockwise rather than one clockwise. And, if let it accumulate and reset to zero, it rotates many times. For example, rotate it 10 times round, and click Reset button. My main objective is to have reset rotate the minimum ...
