Windows GOG DOS Games on M-Series Macs
GOG is great. I bought a few old games from them: SimCity 2000, Theme Hospital, Syndicate Plus. And by old games, I mean games from my childhood that still

Microcode inside the Intel 8087 floating-point chip: register exchange
In 1980, Intel introduced the 8087 floating-point chip, a co-processor that made floating-point operations up to 100 times faster. This chip...

Real-time LLM Inference on Standard GPUs: 3k tokens/s per request
Today, Kog AI launches a tech preview of the Kog Inference Engine (KIE): 3,000 output tokens/s per request on 8× AMD MI300X GPUs and 2,100 on 8× NVIDIA H200 (FP16, no speculative decoding). This preview runs a 2B model, with support for large third-party MoE models coming next at similar speeds.

Raft Consensus with a Minority of Nodes
Raft is a consensus protocol for managing a replicated log across a cluster of nodes. Its key goals are: (1) maintain a consistent replicated log of state transitions, (2) tolerate node failures, and (3) ensure a single leader coordinates all changes while multiple followers replicate. Raft is designed to be…

Blog ran on Ubuntu 16.04 for 10 years. I migrated it to FreeBSD
After a decade on Ubuntu 16.04, I migrated my blog to FreeBSD on Hetzner. Some notes on setting up a VPS with FreeBSD, Jails, Bastille, Caddy reverse proxies, and load testing and benchmarking the blog from four continents.

How fast is N tokens per second really?
Every local-LLM benchmark reports throughput: "47 tok/s on an M3," "180 tok/s on a 4090," "500 tok/s on Groq." Unless you've actually watched tokens stream at those rates, the numbers are hard to internalize. This is the rendering.

The occasional ECONNRESET
Two services running on the same machine. One of them opens a listening TCP socket bound to localhost, the other one connects to that. They exchange data. Every now and then , the service that initiated the connection gets an ECONNRESET while reading data from the socket -- but no other errors show up in the logs, no…

The Fil-C Optimized Calling Convention
Fil-C achieves memory safety even for programs that behave adversarially. That includes casting function pointers to the wrong signature and then calling them, exporting a function with one signature in one module and then importing it with a different signature in another, or even exporting a symbol as a function in…

First public macOS kernel memory corruption exploit on Apple M5
Apple spent five years building hardware and software to make memory corruption exploits dramatically harder. Our engineers, working together with Mythos Preview, built a working exploit in five days.

When “idle” isn't idle: how a Linux kernel optimization became a QUIC bug
We investigated a bug where CUBIC's congestion window became pinned at its minimum floor, causing a performance to plummet. The fix involved correctly measuring idle periods to distinguish RTT wait times from actual application idleness.

How Fast Does Claude, Acting as a User Space IP Stack, Respond to Pings?
Here is a fun thought: if we ask Claude Code to act as a user space IP stack, how quickly will it be able to respond to a ping?

Replacing a 3 GB SQLite db with a 10 MB FST (finite state transducer) binary
Note for numberphiles: all numbers have been rounded to their first significant digit, because I’m a fan of Rob Eastaway’s “zequals” method of getting to the point when it comes to estimation. It’s much more valuable to walk away with the heuristic “some dude got a 300x memory reduction by swapping out a database he…

Lanzaboote – NixOS Secure Boot
Secure Boot protects a system from an attacker that compromises the boot flow. For example, without Secure Boot it is easy to replace the code that reads your disk encryption password and store it somewhere where the attacker can pick it up later. So ideally you want Secure Boot to be enabled to limit the code that…

Can LLMs model real-world systems in TLA+?
Editors’ note: AI has been actively pushing the frontier of applied formal methods for computing systems. In this article, the Specula team wrote about their experience of evaluating LLMs on modeling system code, the basic capability for agentic model checking, using TLA+, a specification language f
