A RISC-V emulator built with ClickHouse SQL. This emulator makes ClickHouse truly Turing complete. We are one step closer to running ClickHouse in ClickHouse. This project/repository isn't dev-friendly yet, I'm just uploading it here as a backup in case my PC catches fire. How it works The system will react to the following insert command: INSERT INTO clickv . clock (_) VALUES () This command will trigger a large set of branched materialized views and Null tables that filter out the progra

CPU cores have become significantly wider over the past decade. Ten years ago, the highest-performance CPUs could decode only up to four instructions simultaneously and execute up to eight instructions. However, top-tier CPUs released in recent years have grown to nearly twice this width. For example, Apple’s M4 processor, released in 2024, can decode 10 instructions simultaneously and execute up to 19 instructions. ARM’s Cortex-X925 processor, also released in 2024, can decode 10 instructions s

Machine Code Isn't Scary The first programming language I ever learned was ActionScript. Writing code for Macromedia's Flash might be the furthest away from "bare metal" as you can possibly get. As I continued learning new languages, this starting heritage stuck with me. I was mostly interested in high-level, "web languages". Low-level languages felt impenetrable. Over time, I learned a bit more about them here and there, but for some reason, this notion stuck with me. Low-level things are scar

We at Johnny’s Software Lab LLC are experts in performance. If performance is in any way concern in your software project, feel free to contact us. There was a rumor I read somewhere related to training AI models, something along the lines “whether we compile our code in debug mode or release mode, it doesn’t matter, because our models are huge, all of our code is memory bound”. I wanted to investigate if this is true for the cases that are interesting to me so I wrote a few small kernels to i

On eval in dynamic languages generally and in Racket specifically posted by Matthew Flatt The eval function is at the heart of a dynamic language, and it strikes many newcomers as an amazingly powerful tool. At the same time, experienced programmers avoid eval , because unnecessary use creates trouble. It’s not easy to explain why eval should be avoided or when it"s appropriate to use eval , but I’ll take another stab at it here. What is eval ? Consider the following “program” in English pro

There are some applications that benefit from running LLMs really, really fast. This low-latency regime encompasses applications like chatbots and human-in-the-loop workflows, where users care a lot about seeing responses come back immediately. Given the importance of these low-latency workloads, we wanted to explore just how fast we can run open-source models on modern GPUs. To really stress-test existing systems, we consider an aggressive low-latency scenario where we generate a single sequen

On Sunday, independent AI researcher Simon Willison published a detailed analysis of Anthropic's newly released system prompts for Claude 4's Opus 4 and Sonnet 4 models, offering insights into how Anthropic controls the models' "behavior" through their outputs. Willison examined both the published prompts and leaked internal tool instructions to reveal what he calls "a sort of unofficial manual for how best to use these tools." To understand what Willison is talking about, we'll need to explain

“Why would you ever want to write a program that changes its code while it’s running? That’s a horrible idea!” Yes, yes it is. It’s a good learning experience though. This is not something you would ever do outside of exploring a curiosity. Self-mutating/self-modifying programs aren’t useful for a whole lot. They make for difficult debugging, the program becomes hardware dependent, and the code is extremely tedious and confusing to read unless you are an expert assembly programmer. The only go

In context: Nvidia recently rolled out a GeForce driver update that quietly made older Intel processors, specifically the Core 2 family, technically compatible with the latest RTX 50-series GPUs. It initially sounded like a promising "loophole" for retro PC enthusiasts, but unfortunately, things haven't played out as expected. The key to this surprising development lies in a single instruction: POPCNT, or "Population Count." This CPU-level instruction is used to calculate the number of bits set

Intro to TTD Time Travel Debugging (TTD) is a powerful usermode record-and-replay framework developed by Microsoft, originally introduced in a 2006 whitepaper under a different name. It is a staple for our workflows as it pertains to Windows environments. TTD allows a user to capture a comprehensive recording of a process (and potential child processes) during the lifetime of the process's execution. This is done by injecting a dynamic-link library (DLL) into the intended target process and ca
