By nature, I'm a mad tig welder with a (mild) titanium obsession who by some cruel happenstance has been forced into the IT security field and computer science (I am in love with it though). Other than breaking down malware, I also love to travel (I do that a lot) and write blog post's regarding world politics and computer programming.https://xed.ro/https://xed.ro/posts/the-plastic-timeline/https://xed.ro/posts/the-plastic-timeline/Persistence archives the past; retroactivity edits it. What the algorithms say about changing history, why one operation inserted at the start can rewrite every answer after it, and the two conditions that decide the price of time travel.Sun, 04 Oct 2026 15:17:00 GMThttps://xed.ro/posts/secondhand-scars/https://xed.ro/posts/secondhand-scars/A corpus is a record of other people's scars, and that is why pretraining works so well and stalls at the frontier, where nobody has been hurt yet.

Caches, garbage collection, log rotation. The interesting design decision in a memory is not what it keeps. It is the policy for what it drops.Sun, 20 Sep 2026 16:17:00 GMThttps://xed.ro/posts/the-mirror-problem/https://xed.ro/posts/the-mirror-problem/A model trained on its own output loses range generation after generation, the tails of its distribution slowly disappearing.

Nobody asks whether retrieval should happen at all. Here's the missing cognitive control plane that turns memory access from a reflex into a decision, with controller architectures, a formal definition, benchmarks, and working code.Fri, 24 Jul 2026 21:00:00 GMThttps://xed.ro/posts/why-smart-companies-stop-knowing-things/https://xed.ro/posts/why-smart-companies-stop-knowing-things/Smart companies rarely fail because nobody has data.
