Writing a storage engine for Postgres: An in-memory table access method (2023)

news.ycombinator.com Unknown 2025-11-23 09:53:15

With Postgres 12, released in 2019, it became possible to swap out Postgres's storage engine. This is a feature MySQL has supported for a long time. There are at least 8 different built-in engines you can pick from. MyRocks, MySQL on RocksDB, is another popular third-party distribution. I assume there will be a renaissance of Postgres storage engines. To date, the efforts are nascent. OrioleDB and Citus Columnar are two promising third-party table access methods being actively developed. Why

news.ycombinator.com Molly Longman 2025-12-08 18:50:46

When Dave Yeager stumbled upon the chamber of shiny, casino-style slot machines, he felt an instant pull. It was his first night of deployment in Seoul, South Korea, and the United States Army officer was in a bad headspace. The September 11, 2001, attacks had just happened, and he had a wife and two children under the age of 5 at home whom he missed fiercely. He felt lost.

A system update for those in the PS5 beta program will enable a new feature for the DualSense or DualSense Edge controller, allowing it to be paired with multiple devices at the same time and quickly switch between them. Beta participants will get access to the new feature on Friday. The DualSense controller can be connected to several devices via Bluetooth that aren't the PS5, including computers (PC, Mac), and mobile devices like smartphones and tablets. However, you can only connect to one o

When Sigterm Does Nothing: A Postgres Mystery

news.ycombinator.com Unknown 2026-01-16 04:43:08

In my opinion, the worst bugs are the ones you decide not to look further into. Maybe the problem only manifests 2% of the time, or when you run the code on a particular brand of toaster. Maybe the customer doesn't supply enough information to begin narrowing down the cause. Maybe you just don't have enough time to track the issue down fully. And everyone eventually moves on. But when you see the same bug strike again months later, you quietly mutter to yourself and wish you'd been persistent

How to store Go pointers from assembly

news.ycombinator.com Francesco Mazzoli 2026-02-27 22:40:24

2025-06-23 How to store Go pointers from assembly The standard Go toolchain comes with an assembler out of the box. Said assembler is highly idiosyncratic, using syntax inherited from Plan 9 and choosing its own names for platform-specific instructions and registers. But it’s great to have it readily available. More mundanely, Go comes with a garbage collector. This post explains how to make these two components play nice, if we want to manipulate Go pointers from our assembly. Preamble: Go’s

The Best Motherboards: AMD and Intel

techspot.com Steven Walton 2026-03-14 12:40:00

With a little more budget, you can get some really nice boards for up around $200. From day one, a stand out which we featured in our early 10th-gen coverage is the MSI MAG Z490 Tomahawk, it's a great quality motherboard priced at $190. In our testing, the Z490 Tomahawk peaked at just 74 degrees running a Core i9-10900K clocked at 5.1 GHz using 1.35v, so you don't need to spend big money to get the most out of Intel's new 10-core processor, despite the fact that it is extremely power hungry when

Relaxed Radix Balanced Trees (2024)

news.ycombinator.com Unknown 2025-11-10 20:05:10

Relaxed Radix Balanced Trees I’m adding immutable vectors to my language, Ivan, and needed to pick a suitable data structure to implement them. Clojure uses Persistent Vectors (PVs) which support lookups, updates, and appends all in ‘effectively’ constant time. However, it doesn’t have efficient insert or merge operations. Relaxed Radix Balanced (RRB) Trees, introduced by Bagwell and Rompf in 2011, address this shortcoming. I had to read a few different papers to properly understand how they w
