How a technically superior but economically isolated solution slowly lost ground to a good-enough one built on infrastructure everyone already owns. Read more ›
First, I want to tell you how exactly I got to this point and why I started researching different options for handling asynchronous I/O on Linux… Last year, my students and I built a reverse proxy server called TinyGate. It was super simple, worker-based, and it basically worked well. Of course, I didn’t expect it to be very fast, but it was an educational project, and since we’d made a real, kind of production-ready tool, I was really proud of it. But my students weren’t as happy as I was - ... Read more ›

We have the pleasure of celebrating the birthday of Blaise Pascal by announcing the release of OCaml version 5.5.0. Some of the highlights in OCaml 5.5.0 are: Module-dependent Functions Modules can now be used as function arguments in a form of lightweight functors. For instance, we can define a function for printing a map generated by the Map.Make functor: let pp_map (module M: Map.S) pp_key pp_v ppf set = if M.is_empty set then Format.fprintf ppf "ø" else let pp_sep ppf () = Fo...

One of the greatest weaknesses of AI agents that read and understand vast amounts of enterprise data is "hallucination"—the generation of plausible-sounding but factually incorrect information. KAIST researchers have developed a next-generation database technology capable of understanding documents, data and relationships among entities all at once. Read more ›

The opening post of a Low-Level Systems Design in Rust series, arguing that the biggest performance win is structural: replace a shared multi-producer cursor that serializes cores through cache-coherence traffic with one private single-writer SPSC ring per producer, converting quadratic writer contention into a cheap O(N) consumer sweep.

CLI Systems has introduced UTFS (μTFS), a simple, lightweight embedded storage system designed for small MCUs. Unlike traditional file systems like FAT32 or EXT4, or even lighter options like LittleFS and SPIFFS used on boards like the ESP32, UTFS is much simpler. It does not use dynamic memory and avoids complex features like wear leveling, making it easier to use on low-resource devices. Designed for flat, byte-addressable memory like raw EEPROM, CPU flash pages, or external SPI/I²C flash, ... Read more ›

Most programmers think of a for loop as a direct instruction to a computer. Write for i in range(1000), and the machine counts to a thousand. That mental model is wrong, and the wrongness is consequential. The distance between the code you write and the operations your CPU performs is not a detail. It is the entire story of modern computing performance. The Code You Write Is a Polite Suggestion When you write a for loop in Python, C, or Java, you are not writing machine instructions. You are ... Read more ›
Unit tests ensure functions work in isolation, but production incidents thrive at the boundaries. This post details a pragmatic, parallel-ready architecture for integration-testing JVM web services. Learn how to isolate tests into a dedicated module, safely simulate flaky external dependencies (like LLMs and Kafka) using Testcontainers and Mokksy, execute concurrent suites without flaky race conditions, and keep your full local test run under 5 minutes—all while running a fully booted, debugg...

Memory models are formal specifications of concurrent-program executions, accounting for weak behaviors introduced by compiler and architectural optimizations. The increase of their number and complexity has spawned efforts for uniform verification across whole classes of models, by axiomatizing the models in an adequate metatheory that admits a uniform treatment. In this work, we formally study Monadic Second-Order logic (MSO) as a metatheory... Read more ›
