We're open-sourcing nexir-mvcc-core, the transactional MVCC engine that powers the Nexir database. The project focuses exclusively on concurrency control and version management, keeping storage, networking, consensus, and query execution outside the MVCC layer. It provides: Timestamp-ordered MVCC reads and writes Intent-based transactions (prewrite / commit / abort) Atomic multi-key batch transactions Guarded (CAS-style) writes Incremental MVCC garbage collection A backend abstraction that allo
Six years ago i was a finance admin. Nobody asked me to code anything, but i was spending an inordinate amount of time per week manually renaming thousands of letters relating to properties the company owned to a rigorous standard. It was so unbelievably mind-numbing that i decided it had to change. The office had a very creaky, very error prone VBA email sender. I learned VBA to fix it, got hooked on the feeling of fixing it, then went looking for ways to solve my post problem. Regex was great

This post is co-written by Nishanth Charlakola from S&P Global. Organizations have a requirement to build high availability and disaster recovery (HA/DR) solutions for their complex SQL Server infrastructure to maintain data availability and integrity. With the rapid pace of cloud adoption, businesses across different industries have realized the value of a successful proof of concept (POC) for any technical project that migrates existing environments to the cloud. For companies of any size, it

Max single-threaded CPUs at scale are a new category of CPUs built for the agentic AI era. Across the creation and deployment of an agentic system, the CPU is on the critical path for reasoning, response time and learning. CPUs are the processor which executes the work the AI model commands: the tool calling, code execution, data processing, KV-cache and result analysis. For agents in AI factories, speed matters. The faster the CPU can run the tool, the faster the agent can perform the tas

How is it done? I'm using Bevy on the client side, while the server is fully custom and written from scratch in Rust using Tokio, Axum, and SQLx. Things like networking, area of interest, spatial queries, replication, and other systems were written by me. I'm using WebSockets as the transport layer. I previously used WebTransport, but some players had problems connecting, so I switched back to WebSockets. The whole game was rewritten by hand, with some architectural improvements along the way. M

Building an MCP client in Python is a great way to test MCP servers directly from your terminal. In this video course, you’ll build a minimal MCP client for the command line. It can connect to an MCP server through the standard input/output (stdio) transport, list the server’s capabilities, and interact with the server’s tools, prompts, and resources directly and deterministically. By the end of this course, you’ll understand that: You can build an MCP client app for the command line us
Hi r/rust! I've been building an MMO authoring IDE in egui and needed a real design system for it — so I built one, and today I'm open-sourcing it.

Not a web port 60+ components (atoms → cells → molecules → organisms, plus a node-editor graph layer), all token-first.

Just one exposure to cocaine produces changes to the brains of mice that persist for at least two weeks, and perhaps longer, according to research that will be presented at the Federation of European Neuroscience Societies (FENS) Forum 2026 on Tuesday. The results suggest that cocaine, a popular drug used by an estimated 25 million people around the world, may rewire the genomes inside cells of the brain’s reward system, called dopaminergic neurons.

The AI Boomerang: They Laid You Off to Save Money. They’re Paying More to Get You Back. Ford spent a year letting AI read its engineering requirements, and the cars kept coming off the line with defects nobody caught in time. So in the spring of 2026 it did the unglamorous thing. It called 350 veteran engineers back to their desks. Not fresh graduates. The gray-haired ones who knew, from decades of scar tissue, where a design goes wrong before any software flags it.

Over the weekend, I released rssCloud Server 4.0 and wanted to discuss how I added WebSub support to the server. WebSub is an alternative protocol that has the same purpose as rssCloud: to notify subscribers of real-time updates. Back in 2020, Dave Jones had suggested I add support for WebSub because they were “close enough in their implementation” that it should be feasible. At the time, I didn’t really know much about WebSub. I had heard of PubSubHubbub and knew it was different fr

The age of AI is upon us — and with it, a new age of telemetry and observability tools for MCP-driven stacks. MCP observability refers to the tools and practices used to monitor, trace, and analyze how AI agents interact with MCP servers, tools, and connected systems. The current slate of tools for MCP observability represents an interesting mixture of different modalities and approaches. Some solutions offer deep, tool-call-level tracing that gives you a highly granular view of every agent in

Lately, I’ve been working on a paper where I optimize some continuous parameters of a flying robot in a hummingbird robot with MuJoCo MJX. One of the early problems I faced was that no learned design transferred to other integrators or timesteps than the one that it was trained on. This means that the gradient descent simply learned the quirks of the numerical scheme rather than any meaningful physics. When learning over physics simulators, it is probably best to have at least a basic understa
