New blog post for this month's Emacs Carnival on underappreciated built-in Emacs features although I'm cheating because I'm talking about a feature that is not actually built in (and I missed the chance when a previous Emacs carnival was on packages... 🤪). The blog post is about rec mode, an all-text database system.
Ross A. BakerThe June, 2026 Emacs Carnival is "Underapprecated Emacs Built-ins." There are about two million lines of code in the core Emacs repo. Send me your favorite hidden treasure. If you're unsure where to look, see some ideas in the post.

Excellent blog post on EWW in Emacs which I read, obviously 🙂, using EWW.

May I recommend… vibemacsing?
Over the last couple of years, I’ve been using my own eval test to gauge the coding capabilities of frontier LLMs. Obviously, the test involves Emacs. The test: write a function that marks the text rectangle under the cursor. At first glance, it seems like a simple test, but in reality it has a whole series of subtleties: it must use mark-rectangle and not a simple set-mark, it must find the rectangle’s vertical and horizontal boundaries (bounded by whitespace, empty lines, or buffer start/end), and it must handle text rectangles made of lines of different sizes. My example use case is trivial: have a series of lines with hostname, IP address, and netmask separated into columns with whitespace, place the cursor on an IP address, and select them all with a single command, excluding the other columns. I tried for several months, but no LLM produced a correct function. Then, in January of this year, something changed: Claude Code generated what I had imagined on the first try. That was a turning point: I realized that the code generated by LLMs could compete with, and potentially surpass, what we humans write.

Part of April's #EmacsCarnival: https://www.emacswiki.org/emacs/CarnivalApril2026 which looks like it is orphaned.
A lot of interesting posts in March's #EmacsCarnival - I enjoyed reading all of them.
In my submission I'm having second thoughts on #Spacemacs usage

texacoEmacs Carnival de Marzo - Confusiones y prejuicios
Cuando llegué a Emacs, llegué por hastío. Sí. Cansado. Recién habían anunciado el final del ciclo de vida de un editor de textos que me encantaba, Atom. Un editor que era extensible, rápido y soportado por la comunidad. Para colmo, la alternativa me gustaba bien poco. Visual Studio Code. De Microsoft. No era la primera vez que tenía que moverme de editor de textos, aprender nuevos atajos de teclados, nuevas ventanas de configuración. En definitiva, todo un nuevo idioma.
This month's Emacs Carnival is on mistakes and misconceptions we might have made when using or considering Emacs:

This is my entry where I describe my mistakes regarding completion (which coincidentally was last month's topic for the Emacs Carnival):
