Writing a storage engine for Postgres: an in-memory Table Access Method

news.ycombinator.com Unknown 2025-11-30 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

More shell tricks: first class lists, jq, and the es shell Preamble It’s not a secret that most common shells don’t have first class lists. Sure, you can pass a list to a program by passing each element in argv (e.g. with "$@" or "${list_variable[@]}" ), but what if you want to return a list? There are a couple of options.

Ceretone Core One Pro Hearing Aids Review: A Blunt Instrument

wired.com Christopher Null 2025-12-07 03:30:00

Ceretone, born on Indiegogo, hit the scene last year with impressively tiny hardware that still remains one of the smallest and lightest hearing aids I’ve ever reviewed. At just 0.96 grams each, the Ceretone Core One were so light they threatened to blow away in the wind. With a price of $349 per pair, they had a similarly minimal effect on your bank account. The trouble with the original Ceretone Core One is that they just weren’t very good as hearing aids. They were not tunable, suffered from
