🚨 PostgreSQL 18: RETURNING now supports OLD and NEW values on UPDATE! #SQL #PostgreSQL
If you're wondering how I get those colorized ping outputs — I use grc (Generic Colourizer). It works with so many tools straight out of the box (df, lsblk, free, ps and more). You can quickly install it with your package manager, for example: $ sudo dnf install grc Add these…
Did you know you can actually drop zeros in an IP address and it still works. For example: 10.20.0.2 → 10.20.2 10.0.0.68 → 10.68 Both reach the same host. It’s one of those neat little IP quirks I use in labs , saves me a few keystrokes every time 😅
Quick Linux tip: The diff command is a useful tool for finding differences between files in the Linux terminal. However, icdiff offers an even better side-by-side comparison with colorized output. $ icdiff config-dev.ini config-prod.ini The output will display both files…
Back when the price tag was so high the designers got time to stamp their mark on it.

This is the kind of autism the government fears.
Asynchronous IO is the best feature In Postgres 18 yet. PG 18 has been released with many exciting features such as UUIDv7, Over explain module, composite index skip scans, and the most anticipated asynchronous IO with worker and io_uring mode which I uncover in this show.…
The SQLite internals tool built by @invisal89 is brilliant in understanding a SQLite file's underlying structure; give it a spin. sqlite-internal.pages.dev
SQLite is used across various projects for efficient data storage and retrieval. Many browser engines, Chromium included, rely on SQLite for various browser functions. The official architecture page is quite an exciting read, with pointers to the code.…
Everyone uses Docker, but very few people know how debug a Docker container. No, I’m not talking about "docker logs", or "docker inspect", or "docker exec" I’m talking about "docker events". You probably don’t even know it exists. But it streams low-level, real-time event logs…
This is so crazy!😱Look at the immersive 360° display at the China National Film Museum in Beijing. The museum opened in 2007, 18 years ago! I can’t believe I just discovered this incredible place till today!
Postgres 18 has been released, with Async I/O support. Previously, all read requests were blocking, but with this update, they are no longer, delivering massive performance gains for read-heavy applications! It's enabled by default on Postgres 18!
💾 SQLite in production? André Arko shows how his app serves 1M requests/month on a $14 Fly.io VM, powered entirely by a single SQLite file. Simplicity wins—until it doesn’t. andre.arko.net/2025/09/11/rai…
UUIDv7 Comes to PostgreSQL 18 thenile.dev/blog/uuidv7 #postgresql #uuidv7
Postgres 18 has been released, which comes with native UUID v7 support! UUID v7 is time-ordered, which means there is less overhead on the indexes. This leads to both reduced reads and writes to your database compared to v4 UUIDs!
Async I/O is going to be a game-changer in Postgres 18
congrats to the @PostgreSQL contributors 🐘 ◆ asynchronous I/O ◆ UUIDv7 ◆ virtual generated columns ◆ temporal constraints ◆ oauth authentication ◆ improved text search ◆ parallel streaming in replication ◆ new wire protocol (first new protocol version since 2003)
