D2 (text to diagram tool) now supports ASCII renders

news.ycombinator.com Unknown 2025-11-06 21:14:41

In the latest release of D2 (0.7.1), we introduce ASCII outputs. Any output file with extension txt will use the ASCII renderer to write to it. Here is an example of their rendering from the D2 Vim extension. The user opens a .d2 file and opens a preview window, which updates upon every save. Perhaps the most useful place for ASCII diagrams is in the source code comments. Small simple diagrams next to functions or classes can serve to be much clearer than describing a flow. Here again the Vi

ChatGPT made up a product feature out of thin air, so this company created it

arstechnica.com Unknown 2026-01-23 20:59:25

On Monday, sheet music platform Soundslice says it developed a new feature after discovering that ChatGPT was incorrectly telling users the service could import ASCII tablature—a text-based guitar notation format the company had never supported. The incident reportedly marks what might be the first case of a business building functionality in direct response to an AI model's confabulation. Typically, Soundslice digitizes sheet music from photos or PDFs and syncs the notation with audio or video

SVGs that feel like GIFs

news.ycombinator.com Unknown 2026-01-25 17:23:05

The moving image below is only 49Kb and has an incredibly high resolution. It's similar to a GIF but instead of showing moving images, it shows moving SVGs! The best part: Github supports these in their README.md files! Getting these to work involves asciinema and svg-term-cli. After uploading the asciinema you can use the tool to download a file that you can immediately click and drag into a README. It's something that I'm using extensively on bespoken. How it works? I was surpised to learn

Adding a feature because ChatGPT incorrectly thinks it exists

news.ycombinator.com Unknown 2026-01-30 14:58:09

Written by Adrian Holovaty on July 7, 2025 Well, here’s a weird one. At Soundslice, our sheet music scanner digitizes music from photographs, so you can listen, edit and practice. We continually improve the system, and I keep an eye on the error logs to see which images are getting poor results. In the last few months, I started noticing an odd type of upload in our error logs. Instead of images like this... ...we were starting to see images like this: Um, that’s just a screenshot of a Chat
