bisql (Clojure Data Access Library) released v0.4.0: Support Malli Validation

Bisql I'm building Bisql, a data access library for 2-way SQL in Clojure. https://github.com/hatappo/bisql Since it's “2-way,” I called it bisql with the bi- prefix. It is pronounced like bicycle. A common weakness of SQL-template libraries, not just 2-way SQL libraries, is that writing all SQL as templates can become tedious. To address that, many SQL-template libraries support a q...

Agent2Agent Protocol, IBM Vault, & OAuth 2.0 On-Behalf-Of

I wrote a blog on using AI agent authorization with Agent2Agent protocol and IBM Vault that focused on setting up Vault as an OIDC provider to authenticate and authorize requests from an Agent2Agent client to a server. While it works, the post missed something rather critical: identity delegation. Basically, if I am an end user, I want to delegate my Agent2Agent (A2A) client to act on my behalf to...

SIMDVec Supercharges Vector Hunt

Elasticsearch simdvec is the engine behind every vector distance computation in Elasticsearch. It provides hand-tuned AVX-512 and NEON kernels for every vector type Elasticsearch supports. In bulk scoring (where production actually lives), the hand-tuned SIMD kernel library powering all vector distance computations in Elasticsearch, processes float32 vectors at 95 ns/vector. FAISS is at 165 ns. ...

I built FuelFox to make finding cheap fuel in the UK much faster

Yesterday I launched FuelFox, an iPhone app and website for finding live fuel prices near you anywhere in the UK. It's built on the official government forecourt feed, which covers roughly 8,000 stations across the UK. The goal is simple: open the app or website and immediately see fuel prices near you. I know I'm not the first to build in this space, and plenty of fuel apps and websites existed...

The Sweet Lure of Prediction Arb: How I Tried to Speedrun a Rust Monitor (and Fried My Brain)

It all started with some casual research. I was deep down the prediction market rabbit hole, trying to figure out if there was any real alpha in playing options strategies based on crypto crowd expectations. Then I spotted it: the discrepancies. You could buy >Yes< on one platform, grab >No< on another, and pocket a risk-free delta. The spreads weren't massive, but they were definitel...

5 Frontier Models Compared

I kept picking the wrong model. Not because I didn't know the benchmarks. Because the benchmarks don't tell you what a model actually costs when you're running it daily, or whether it holds up across a 3-hour agent session, or whether it can fit your whole codebase without truncating half of it. Five frontier models shipped in early 2026. All of them are good. None of them is good at everything....

Fintech on Go: what the language solves in a crypto backend (Part 1)

A two-part case study on building an ERC-20 rewards service in Go, covering goroutines, replicas, and the consistency problems that surface before a transaction is signed. Part 1 tackles nonce sequencing and idempotency. TL;DR A crypto payments backend holds state in two systems that disagree often: Postgres and the Ethereum chain.
