    Superlogical

    Their words

    Superlogical makes it up at scale and there is an early breakpoint with busy terminals and clients where we use significantly less memory than tmux or anyone else.

    credit where credit is due tmux has excellent memory usage for empty states.

    Ghostty

    Their words

    I have no intention of ever commercializing Ghostty. To solidify this, I donated the entirety of Ghostty to a federally recognized non-profit in 2025.

    Zig

    Their words

    Zig is exceptional software: ambitious, practical, independent, and unusually serious about quality. Ghostty exists in large part because Zig made it possible for me to build the kind of software I wanted to build. This is why I support Zig.

    Amp

    Their words

    I particularly like to combine this with slower, more thoughtful models like Amp's deep mode (which is basically just GPT-5.2-Codex) which can take upwards of 30+ minutes to make small changes. The flip side of that is that it does tend to produce very good results.

    GitHub CLI

    Their words

    Agents are good at using gh (GitHub CLI), so I manually scripted a quick way to spin up a bunch in parallel to triage issues.

    Gemini

    Their words

    The command palette that ships for macOS in Ghostty today is only very lightly modified from what Gemini produced for me in seconds.

    • The best terminal multiplexer is the one nobody has to learn; needing to be learned at all is the first design failure.
      I can't tell you the number of people over my career that have said "I tried learning tmux" First problem: the fact you have to "learn it" at all. The world's best multiplexer is the one you don't have to learn. It just works.

    • A low-effort AI-designed landing page costs a product its audience before the product itself is ever judged.
      I'm so incredibly tired of seeing low-effort AI-designed web pages. I basically bounce off any new product immediately when I see it (never get a chance to judge the product itself). Lots of thin lines, glowy styles, inconsistent fonts, lots of monospace.

    • Chatbot interfaces are the wrong tool for meaningful coding work, because you are mostly hoping the model recalls the right answer and correcting it requires a human in the loop.
      Immediately cease trying to perform meaningful work via a chatbot (e.g. ChatGPT, Gemini on the web, etc.). Chatbots have real value and are a daily part of my AI workflow, but their utility in coding is highly limited because you're mostly hoping they come up with the right results based on their prior training, and correcting them involves a human (you) to tell them they're wrong repeatedly.

    • Effective use of AI coding tools requires domain expertise: the tool should be used as an assistant, not as a replacement for the engineer.
      This is intentional and I believe good AI drivers are experts in their domains and utilize AI as an assistant, not a replacement.

What is a korrent?

A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.

Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.

Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.

Where they publish

About the English under a post

Some people here publish in a language other than English. Where they do, this site shows a machine translation beneath the post, in this typeface — the site's own, not theirs.

The post itself is never changed, moved or hidden: what is set in the serif above is exactly what the person published, and it is what to quote them on. A translation can be wrong in ways that matter, especially about tone.

Only the post's own words are translated. A quoted post, a linked article and a belief on korrents.com are left in their original language.
