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…
WebContainers are now supported on Firefox for desktop and mobile as a result of StackBlitz and Mozilla collaboration! 🥳
July 1, 2020: Post updated to take care that Amazon EFS increased file system minimum throughput, when burst credits are exhausted, to 1 MiB/s. I am very happy to announce that AWS Lambda functions can now mount an Amazon Elastic File System (Amazon EFS), a scalable and elastic NFS file system storing data within and…

Highly complex services, such as those here at Facebook, have large source code bases in order to deliver a wide range of features and functionality. Even after the machine code for one of these se…
Go 1.25 includes a new experimental garbage collector, Green Tea.
View, search and download security bulletin information for individual IBM product versions and releases.
For developers, databases are basically magic. Like Penn & Teller, this blog post is set to break the illusion. Databases are just like any other code, they have algorithms and processes. These algorithms and processes are meant to improve performance, but can cause limitations if they are not expected.
In this post we look at the impact of a new feature of Ruby 3.4 on Shopify’s monolith.
Conservancy's GPL Compliance Project for Linux Developers is pleased to announce its role in assisting Samsung in a recent public compliance issue. The compliance issue was brought to Conservancy's attention when source code of an exFAT filesystem driver for Linux was unintentionally released via GitHub, and…
This week's Internet cable cuts in the Baltic Sea have been widely reported, even as attempts to understand their cause and impact continue. We turn to RIPE Atlas to provide a preliminary analysis of these events and ask to what extent the Internet in the region has been resilient to them.
This article details two bugs discovered in the NVIDIA Linux Open GPU Kernel Modules and demonstrates how they can be exploited. The bugs can be triggered by an attacker controlling a local unprivileged process. Their security implications were confirmed via a proof of concept that achieves kernel read and write…
Scylla is a distributed wide-column 1 database which originated as a C++ port of Cassandra, aiming for improved performance. It supports both Cassandra- and DynamoDB -compatible APIs, and is intended for high-throughput, low-latency workloads, including analytics, messaging, and other time-series data.
In this blog, we’ll focus on techniques that improve latency by optimizing both the prediction server and client.
The official home of the Erlang Programming Language
Performance tuning is not trivial, but you can go a long way with a few basic guidelines. In this blog, we will discuss how you analyze the workload of the database, and then review a list of important configuration parameters to improve the performance of PostgreSQL.
This post will describe my recent work on Cranelift as part of my day job at Mozilla. In this post, I will set some context and describe the instruction selection problem. In particular, I’ll talk about a revamp to the instruction selector and backend framework in general that we’ve been working on.
Building systems that manage globally distributed data, provide data consistency and are also highly available is really hard. The beauty of the cloud is that someone else can build that for you.
At Waymo, our mission is to be the world’s most trusted driver. We know trust is built through consistent behavior over time—earned through every mile we drive and every interaction we have with the community. This past Saturday, as a widespread PG&E outage cut power to nearly one-third of San Francisco, our service…
At Photon, we are developing the world’s most complete iMessage API (with RCS and SMS fallback) for agents: infrastructure that lets Agents reliably communicate through one of the most native messaging interfaces people already use. While building it, we run Mac-backed systems continuously and care a lot about making…
Project Loom is one of the major “projects” in which Java is moved forward, alongside the perhaps better known projects Amber and Valhalla. It will bring “virtual” threads with low resource footprint and low cost of blocking to the Java plaform. Here is my annual advent season update, this time with a focus on…
