@_chenglou made pretext 5 days ago.

To see how powerful it was, I used it to build a multiplayer game. It's like https://t.co/3LaUJ4nIqr but in a sea of Pretext words.

This would not've been possible without pretext. But with it, it was a 3 day build all-in.

My dear front-end developers (and anyone who’s interested in the future of interfaces):

I have crawled through depths of hell to bring you, for the foreseeable years, one of the more important foundational pieces of UI engineering (if not in implementation then certainly at least in concept):
Fast, accurate and comprehensive userland text measurement algorithm in pure TypeScript, usable for laying out entire web pages without CSS, bypassing DOM measurements and reflow

@raroque Sent you a DM!

@MattZirwas Oh, and also the idea of diets high in unsaturated fats making your skin more prone to burns

[Nick Cernera @cerneradesign]

Hey Matt, amazing post.

I’ve read here and there about a few different mechanisms that I’d love your thoughts on:
- The idea of a “sun callous”; becoming better adapted to the sun and burning less easily by spending more time in low UV sun earlier in the season before summer hits
- Similarly, spending time in the early morning sun if you intend on getting peak UV sun later
- The importance of not wearing sunglasses to prevent burns

I read some post a while back about someone with fitz type 1 skin who was spending WAY more time than you listed in the chart in the sun without getting burned because they followed the above and had a “thick sun callous”.

Any thoughts there?

@raroque Is this already released? I’ve tried Amy a while back and it didn’t stick but this could be a game changer for me

Today we're launching @soffi_dev.
I spent most of my career shaping products but relying on others to build them. Then AI changed that.

Soffi lets designers and PMs work directly on real, deployed software alongside engineers.

Not mockups. Not prototypes. The actual product.

@HeyGen I forgot to RT the first time, but now I did 🫡

[Nick Cernera @cerneradesign]

@HeyGen CLI

[HeyGen @HeyGen]

Your AI agent can now generate and ship videos.

HeyGen CLI is now live.

Run one command and your agent handles it all:
script → avatar creation → video → delivery

All from the terminal. Just your agent and the CLI.

RT + Comment “CLI” and we’ll DM API credits (must follow)

@JanJurdik @marclou Should be fixed, I got up to 250k with no crash. Also made bots way better and smarter

[Nick Cernera @cerneradesign]

@JanJurdik @marclou Thanks for letting me know man, I’ll look into it. I don’t think I ever tested past 30k!

Vibe coding is more addictive than any video game ever made (if you know what you want to build).

> found a powerful new frontend dev library, pretext
> made an https://t.co/3LaUJ4nIqr clone with it in 3 days

crazy that in 2026 you can casually create products that teams have spent hundreds of hours on in the past
