One of our Rust services started to show an odd memory profile. This is the story of how we investigated the issue.
Neon’s serverless driver redirects the PostgreSQL TCP wire protocol over WebSockets. This makes ordinary, fully-functional PostgreSQL connections accessible from new environments — including serverless platforms like Cloudflare Workers and Vercel Edge Functions. A key feature of these environments is that state is not…
AI is powered by a virtuous circle of data, algorithms (“models”), and compute. Growth in one pushes needs in the others and can grossly affect the developer experience on aspects like usability and performance. Today, we have more data and more AI model research than ever before, but compute isn’t scaling at the same…
In the recent past, a typical client/server environment consisted of multiple clients connected to a central database server. A central database architecture is a system where all data is stored in a single centralized location. When client A from Si...

Vigneshwaran C explained the internals of PostgreSQL Logical Replication during PGConf India - if you were not able to attend, you can read all here.
In this blog post we discuss the details of two vulnerabilities we discovered in the Trusted Platform Module (TPM) 2.0 reference implementation code. These two vulnerabilities, an out-of-bounds write (CVE-2023-1017) and an out-of-bounds read (CVE-2023-1018), affected several TPM 2.0 software implementations (such as…
I’m excited to announce that the translation of the “ PostgreSQL 14 Internals ” book is finally complete thanks to the amazing work of Liudmila Mantrova. The final part of the book considers each of the index types in great detail. It explains and demonstrates how access methods, operator classes, and data types work…

ESET researchers are the first to publish an analysis of BlackLotus, the first in-the-wild UEFI bootkit capable of bypassing UEFI Secure Boot.
The Long Now Foundation fosters long-term thinking. Our work encourages imagination at the timescale of civilization — the next and last 10,000 years — a timespan we call the long now.
Fly.io Distributed Systems Challenges
Tailscale v1.36 for macOS features a significantly reduced binary size (going from 92MB to 56MB). The effort started out with a chance observation about a surprisingly large executable, and ended up involving some creative approaches using dlopen.
