Systems that survive contact with reality

Retries, search, merges and the edge of your app

The network drops, the retry duplicates a payment, the search hands the model the wrong passage, the response is not the data you asked for, and two people edit the same line at the same second. Four interactives and the writing on why all of that is the normal case.

  1. 01 Interactive Retries and slow responses The network drops in the middle of an operation. Press the button twice and see what ends up in the database — with an idempotency key and without one.
  2. 02 Interactive How search over your documents works Move the sliders and watch a search pipeline decide what the model is allowed to see — and what happens when it is fed the wrong passage.
  3. 03 Interactive The edge of the app Everything arriving from outside is untrusted. Break one link at a time and watch where the chain stops and what the screen shows.
  4. 04 Interactive How two people type in one line without losing a letter Two cursors, one line, nobody holding the pen in the middle. One slider takes an index-based merge apart and rebuilds it out of addresses that sit between the letters.
  5. 05 Article AI Will Not Remove Overengineering. It Will Accelerate It Why models produce excessive solutions by default, which natural brake on complexity disappeared, and how to use AI as an editor rather than a generator.
  6. 06 Article The Lithuania Breach and Why I Do Not Like the Phrase “I Told You So” Why incidents like the Lithuania data breach show the need to rethink access infrastructure, authorization, and modern security approaches.
  7. 07 Article Connectors Melt on Nvidia, Gigabyte and Sapphire, and You Get the Blame Three generations of cards, different vendors, one failure pattern: 12VHPWR and 12V-2x6 examined through physics, safety standards and warranty terms.
