Experimenting with annotation-based image editing Still slop, but this interaction of drawing overtop to communicate intent feels pretty good overall

Design Mode for Cursor Introducing a new way to design right where you code.

At @cmmnknwledge, we’ve been building a new stylus-first tool for doing work on your iPad. We’re looking for beta testers who’d like to try this out and shape this experience with us. Comment below to get in touch!

I don't understand why Apple deprecated this class; I think it's cool.

People underestimate how much speed and latency defines what you’re doing- it’s not just about doing the same thing but faster / slower. For ex “sketching” is fundamentally about drawing quickly. If you take an hour to sketch something, suddenly it’s a “drawing”, and you’d never refer to a masterpiece that took a year to complete as “a sketch.” It just doesn’t emphasize the time and effort. Likewise if you had a pencil that could only draw a point on paper every 10s, it would be a plotter. The act of sketching with a pencil is defined by its speed, messiness, and responsiveness directly- and other tools that exhibit this kind of speed / feedback loop have “sketchyness” properties (not a coincidence that we call processing /p5 scripts sketches because of this)

David Ogilvy, the “Father of Advertising” invented a marketing trick in 1952. This technique helped him generate $1.4 billion in sales. Apple and Nike use it in every marketing campaign they run today. Here’s the technique: (and how you can use it to influence others)

说起来几年前写了个用 NSButton 播放 bad apple 的玩具,实现上通过计算两帧的 diff 来增量更新 cell 的状态,在当时的 macOS 上丝般顺滑。今天心血来潮在 macOS 26 上跑了一下,结果卡成 PPT 了,才知道好多 AppKit 组件渲染都用 SwiftUI 重写了 😅 这是老系统在虚拟机的效果:

When I was at Apple, I loved working on micro interactions that you see all over the OS. Now that I’m not an apple I still like to solve for these little problems that really annoyed me. In this case, I designed a backspace button with a speed controller, so by just pressing it you can delete by letter and then immediately by word as you stretch it, without having to wait (like it usually does on the OS) and then if you stretch a little more, you can speed delete through words… I’m also working on another one where you can repair the words if you over-deleted it by accident 😜 (it also has haptic feedback, which makes it really fun)

Apple of the past: Live Real humans on stage Live demos Other humans around Public settings Apple Today: Async Highly produced videos w/ a lot of effects No live demos Isolated in empty rooms on the campus / green screens —— Simply lacks a core sense of humanity

I reverse engineered Apple's thermal logo effect. It’s a Three.js shader that combines 4 inputs: - A video texture heat map - A mouse-driven heat map - An Apple logo mask - A thermal-style color palette Explanation below

I created this virtual keyboard with Gemini 3.5 Flash last night. It's an old hand at these tasks.

I’m reverse-engineering the Google AI mouse pointer and making it Open Source! It sees your screen. You can freeform paint anything and ask AI to modify it. It understands the app or window you mean. It can click, type, edit, navigate, and even write + execute code. A tiny cursor becoming a real computer-use agent. Made with the help of @trycua which is an AMAZING reference for computer use Sorry @GoogleDeepMind but I had to do this @heyclicky Started a revolution and we will be the ones to win Also credits to @BuildwithOmkarr for the help Feel free to modify it , update it and make it your own, we gotta beat them at this.

@swyx And for the love of the demo gods, have a video recording of your demo working just in case

sorry to the haters but this is a very compelling sequence of product demos. the big question is they can get a cursor-like market share lead before openai clones it

My mind was blown away demo after demo today at @southpkcommons i rarely inspired by tech demos but this one is definitely an exception goated folks from @tldraw @OrionReedOne @TodePond we are so early. future of computing is so bright i am blinded right now

Good morning!! We are so excited to announce that @paper is open for sign ups today. And we thought it'd be fun if everyone could see their logo like the Apple heat map invite. So you can just upload your logo and see it. Link in the thread. We think you're gonna love it!

@tldraw @kylebrussell This is such a good demo tweet. Like, completely independent of the actual tool, the way you framed it + the video itself is super tight. I salute you.

@rsnous @abanduk @navaneethmn Here's a screen recording of a quick demo. (I'm running a debug build in an emulator here which is why it's in a macOS window.)

VCs (or anyone, really) giving advice to first-time founders

this is how I know you have shit UX

Founders: in your demos you want to be going for “oh wow” moments. Because the status quo is your enemy, you need strong emotional responses to your product to catalyze a desire to change. If you’re not hearing “oh wow” in your demo, you should be worried. Wrong script. Product isn’t there yet. Wrong target prospect. Something else. You need “wows.”

This tweet blew up more than I expected! So here’s a demo you can try to see how it works! 👇

I am a fan of demos and dumb questions over pontifications and presentations.

Most startups blow the demo as they think it’s a scalable, scripted demonstration of the product. A demo should never be scalable and/or focused on the product. If it is, send a video - you don’t need a sales rep wasting their time. A great ‘demo’ is: >>> sharing your understanding of what you learned about them (demonstration of listening and alignment) >>> storyline where they are today and where they’ll see initial time to value (demonstration of near-term-expected value; everything else is abstract) >>>prospect guiding you/asking questions (demonstrating their intent)

It's so easy to grow developer products. "Just" build incredible demos that show off the technology's capability. @mixedbreadai cooked so hard here. Instant multi-modal AI search, demo'd with the National Gallery of Art dataset. Everything just works and looks fire. https://t.co/NISCM7OFCu http://nga.demo.mixedbread.com

Founders: Turn your demo into a story: 1. Current state (their pain) 2. Future state (the dream) 3. Bridge (your product) 4. Proof (customer examples) 5. Next steps Never demo features without context. Stories = 2x better retention than features.

Love making these small interactions; swipe back to easily close what's open. Even before it's fully presented, which does make a difference to the experience. Available in the alpha today.

Founders: Demo environment checklist: 1. Customer-like data (never dummy data) 2. Industry-specific examples 3. Offline-proof key screens 4. Competitors' logos removed 5. Customized workflows Generic demos = lost deals.

Inspiring demo! Sit back and talk to your computer with high-level instructions, collaborating on a larger document.
