There's a moment in almost every RAG project where someone asks the question that decides your next two years of ops work: "Do we actually need a vector database, or can Postgres just do this?" It's a better question than it sounds, because the honest answer isn't "use Pinecone" or "use Postgres." It's "it depends on numbers you probably haven't measured yet": how many vectors, how aggressively you filter, how much you care about the absolute ceiling of queries per second. Most teams pick bas... Read more ›

Proxmox migration assumptions are the part of the VMware exit that doesn't appear on any migration checklist — and the part that causes the most damage after go-live. The migration succeeded. Six weeks later, a storage event occurred. The runbook assumed vSphere behavior. Proxmox behaved correctly. The runbook didn't. That's when the migration actually started. That team wasn't unlucky. They were carrying assumptions nobody audited. Proxmox isn't replacing VMware. It's replacing assumptions —... Read more ›
I'm a Norwegian calligrapher, typographer, book designer, and freelance type designer with 36 years of professional experience. For 30 years I taught typography and related subjects to graphic design students. My work sits at the intersection of calligraphy and type design, with a particular interest in how historical letterforms inform the typefaces we use today. More about my work: Read more ›

The creation of the Logo programming language wasn't merely about coding. It was Papert’s (and the team’s) way of enabling students to 'think about thinking', to visualise and control their ideas tangibly. This marked one of the earliest instances of technology being used as a cognitive partner. Read more ›
Sampling from high-dimensional, non-log-concave distributions with unnormalized densities is a fundamental challenge in machine learning, particularly when the exact gradient of the potential is unavailable and must be approximated via stochastic gradients that exhibit high variance under a fixed budget of gradient computations per iteration. Although variance reduction techniques such as SGD with momentum, STORM, and PAGE have demonstrated impr... Read more ›
In the context of control theory and automata theory, controllability and observability are dual concepts describing the capacities (1) to control the state of a system and (2) to detect the state of a system from observations. In automata theory, the alternative term reachability is frequently used in place of controllability. Read more ›

Since my main practice is typographic posters, the name Typoposterized was proposed by exhibition curators as a pun on both typography and pasteurized milk, safe from harmful bacteria (or safe from anything except of typography). The poster consists of digital lettering, acrylic paint applied to clumps of paper, the playful Onlysans by Daria Cohen, and the somewhat stricter, more functional and rhythmic FL Ar... Read more ›
CozoDB is an embedded relational-graph-vector database created by Ziyang Hu and the Cozo Project authors. It does Datalog, vector search (HNSW), and full-text search in a single embedded engine and was created with the vision to be the “Hippocampus for AI”. Unfortunately, the project went quiet after December 2024. KuzuDB, another embedded graph database with vector and full-text indexes similar to Cozo, was archived in October 2025. Read more ›
So, you adopted event-driven architecture because your system was a rat’s nest of coupling, and events were the answer to decouple it. But now debugging is a nightmare. You have events coming in out of order. You have retries causing duplicates and multiple different side effects. Local development is a pain. It’s frustrating, right? But… Read More »Stop Blaming Event-Driven Architecture The post appeared first on <a href=" Read more ›
Unstructured text provides decision-makers with a rich data source in many domains, ranging from product reviews in retail to nursing notes in healthcare. To leverage this information, words are typically translated into word embeddings -- vectors that encode the semantic relationships between words -- through unsupervised learning algorithms such as matrix factorization. However, learning word embeddings from new domains with limited traini... Read more ›

Joint Embedding Predictive Architectures (JEPAs) are a leading approach to world model representation learning. We identify a failure mode in JEPA-based world models grounded against two qualitatively distinct external signals: physical dynamics (sparse, high-magnitude, constraint-satisfying gradient corrections) and social-behavioral dynamics (diffuse, distribution-matching corrections). We term this Objective Interference Collapse (OIC): we ar... Read more ›
