Postgres data stored in Parquet on S3: LTAP architecture explained
Almost every traditional database keeps its write-ahead log and data files on one machine's disk, which is the root cause of data loss risk, expensive read replicas and high-availability clones, and analytics queries that drag down transactions.

Memory Safe Context Switching
This document describes how Fil-C supports longjmp , setjmp , setcontext , getcontext , makecontext , and swapcontext in a totally memory-safe way. In particular, no misuse of those APIs in Fil-C can lead to stack corruption or any other violation of Fil-C's capability model.

Microsoft Needs Windows Lite
Microsoft is losing Builders fast. They're switching to MacOS and Linux. The biggest pull keeping people on Windows, outside of shear inertia, is content creation and gaming. However, even these are falling to Linux.

WATaBoy: JIT-Ing Game Boy Instructions to WASM Beats a Native Interpreter
A Game Boy emulator runs faster than a native interpreter by dynamically recompiling SM83 to WebAssembly, effectively making JIT possible on iOS.

Dissecting Apple's Sparse Image Format (ASIF)
At WWDC 2025, Apple announced macOS 26 Tahoe. One of the new features in macOS Tahoe is a new disk image format: ASIF. Designed for use with virtual machines (its documentation lives under the Virtualization framework), ASIF takes a lot of inspiration from existing virtual disk formats. Practically, that means it’s…

Engineering for Bounded Cognition
The mind that builds software is far smaller than the software it builds, and almost everything good in engineering is a way of living with that gap.

MicroVMs: Run isolated sandboxes with full lifecycle control
AWS launches a new serverless compute primitive, AWS Lambda MicroVMs. VM-level, isolated sandboxes with no shared kernel or resources between sessions. Rapid launch and resume, full lifecycle control, state preservation up to 8 hours, no infrastructure to manage.

In praise of memcached
If you happen to find yourself in a sysadmin position, or a position where you just so happen to maintain someone’s infrastructure , chances are that at some point in time the topic “we need a cache” comes up.

Epoll vs. io_uring in Linux
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…

Alice is impatient
Meet Alice. Alice uses your web service. Alice, like most humans, measures her time in seconds and minutes. Alice says your service is slow. You tell Alice that the mean request to your service completes in 100ms, but Alice says that her mean wait time is 1s.

Surprising economics of load-balanced systems
I have a system with c servers, each of which can only handle a single concurrent request, and has no internal queuing. The servers sit behind a load balancer, which contains an infinite queue. An unlimited number of clients offer c * 0.8 requests per second to the load balancer on average. In other words, we increase…

Zigzag Decoding with AVX-512
I’ve been working on speeding up AVX-512 vertex decoding in meshoptimizer recently; in the process I stumbled upon two optimizations that I did not end up using but I thought they might be fun to write about! The optimizations that actually made it in require some higher level background / explanations that will have…
