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 ›
Even if Shor's Algorithm is now implementable inside ten years, symmetric keying should still be trustworthy if we fix RSA with PQC methods. Don't throw the baby out with the bathwater! Read more ›

Executive Summary: To eliminate race conditions in a high-concurrency ticketing system, I implemented PostgreSQL's FOR UPDATE clause for row-level database locking alongside Go worker channels for in-memory queue serialization. This approach completely prevents inventory over-selling by guaranteeing singular data mutation execution even under flash-sale load. If you have ever built an application that handles live event ticketing, flash sales, or limited-inventory drops, you know the dread of... Read more ›
CVE-2026-42530 & CVE-2026-42055: F5 Patches NGINX Vulnerabilities F5 has released out-of-band security updates for two NGINX vulnerabilities that can affect exposed web infrastructure: CVE-2026-42530 and CVE-2026-42055. The first issue affects NGINX’s HTTP/3 QUIC handling. The second affects specific HTTP/2 and gRPC proxying configurations. Both can be triggered remotely and may cause NGINX worker processes to […] Read more ›
I realized that every time I talk about linker scripts, I say that most programmers won’t ever see one unless they work with embedded systems, but I never go deeper than this. I did that again in Making of Doppelgänger and Crypto/Reverse or how to write your first Read more ›

🚀 How Lightweight LLMs Can Use Tools Without Large Compute: A Prompt-Driven Tool-Calling Approach AI #LLM #MachineLearning #AIAgents #PromptEngineering #OpenSourceAI 🚀 Introduction Large Language Models (LLMs) like GPT-4 or Claude are extremely powerful, but they come with a major limitation: they require huge computational resources. But what if smaller, open-source models could also perform complex reasoning tasks—without needing massive GPUs? This question led to my research: “Prompt-Drive... Read more ›
, including support for , automatic table creation and a whole lot more. I released , the first release candidate for sqlite-utils v4. The major version bump indicates some (minor) backwards incompatible changes, so I'm interested in having people try this out before I commit to a stable release. New feature: migrations There are two significant new features in this RC compared to the previous 4.0 alphas. The first is support for database migrations. This isn't a completely new implementation... Read more ›

The biggest issue in font design seems to be kerning. I spend about eight times longer messing around with kerning than I do with actually making the design. Kerning is always the first thing that gets criticised; and the inevitability of 'missing one' is a huge frustration. What's the best way to ensure decent kerning? FontLab's automatic kerning of certain pairs (but not all pairs) is 'non-optimal' – but it strikes me that kerning is exactly the sort of thing that computers ought to be doin... Read more ›

One AI agent answering a question is useful. Five agents that divide a complex task, pass state to each other, and act on live enterprise systems is a meaningfully different category of system. It also carries a meaningfully different category of operational problems. Multi-agent orchestration is the architectural pattern that makes the second case coherent. But a lot of teams prototype multi-agent systems in a weekend and then spend months figuring out why production is unpredictable, expens... Read more ›
Maven Central is introducing publishing usage visibility and limits for high-volume publishing activity. These changes are focused on publishing patterns that operate at commercial or infrastructure scale: unusually large artifacts, high file counts, very high release frequency, or repeated high-volume publishing across an organization's namespaces.

I’ve been working on in meshoptimizer recently; in the process I stumbled upon two optimizations that I did not end up using but I thought they might be fun to write about! The optimizations that actually made it in require some higher level background / explanations that will have to wait until another day :) Both optimizations discussed here touch upon two new (for me) features of AVX-512 that I haven’t had a chance to experiment with until now, and both apply to the same problem: how to de...
