Just went to a cafe for breakfast. Their menus are brass, laser-etched QR codes bonded to the tables. And they all point to…

The theory that Apple nuked their iOS keyboard to encourage more people to use voice dictation fails to take into account the fact that dictation is even worse.

On a call like ‘One sec, it logged me out. Oh, I need 2FA. Where’s my phone? FFS, copy/paste isn’t working. Right, I’ll just type it. Fuck, it timed out. One sec. Right, done—fuck OFF, password reset. Right, let me open my email. Oh. I’m logged out…’

I have a daily #Vim tip set up in ChatGPT. I has access to my `.vimrc` and sends me something relevant. Sometimes — like today — it’s stuff I already know, which is unavoidable, but other times there’ll be a real gem. A nice little companion to my morning coffee.

❓ For years, my email process has been to draft in Markdown in Vim, copy/paste plaintext into a GitHub Issue, copy back out of the preview (rich text), and paste into Gmail. Not only is this laborious, it can carry copy/paste artefacts which is a bad look in the age of AI.

Has anyone got any better workflows/extensions to support writing long emails in Markdown but sending in rich text?

I’m writing a series of workshops for one of the most recognisable brands on the planet (you’ve heard of them). A complete custom curriculum from the ground up. This might be one of the most comprehensive bits of learning I’ve ever put together!

🧑‍🍳 I have multiple custom GPTs that are trained intently around my own needs. This was a chat with Pierre, my chef pal. Today, I walked around @Costco ONLY taking photos of labels. Then I fed the photos to Pierre and asked… 👈 my input 👉 Pierre’s output
