ceiling is being raised. cursor's copilot helped us write "superhuman code" for a critical feature. We can read this code, but VERY few engineers out there could write it from scratch.

The thing about being an SF tech bro is you don’t realize how much it unconsciously infects all of your aesthetic decisions. You’ll buy a sick pair of shoes and then go to a different city and everyone will be like “oh yeah those are the tech bro shoes”.

Make a product so cool people think it’s fake.
LOL it’s funny how easy it is to fool everyone. Just fyi this esp 32 display is simply incapable of rendering such a high resolution and such a high frame rate animation. They simply didn’t do anything besides just editing a video on top of the black screen. Easy million bucks.

A central feature of recent Apple software is wild inconsistency in attention to detail. Invest a ton of effort in a novel subpixel rendering technique only to break the entire animation in the next OS release
For reference, Apple’s Dynamic Island employs subpixel level rendering optimized for the iPhone's RGB subpixel structure, resulting in cleaner cutouts and smoother, more precise animations. This cannot be observed through screen recordings, instead, it becomes clearly visible

Control over Bluetooth – shipping with @__littleguy dev kit!. Independently control eye state and look direction. This is a great way to use iPhone sensors, make API calls, or run whatever business logic you want. These are demo eye states btw, you can make your own in Lark!

The Browser Company is a perfect modern simulacra of like old 90s Mac software businesses. Branding, funding, announcements, cool HQ, dramatic storytelling arc (lol) – it’s all so expertly crafted. I’m bearish but the art of it all is something to learn from.

People in tech don’t realize how many insane artists are on here. You can and should hire them to do brand & design. You’ll end up with something way more unique and fun than anything an agency will give you.

“Taste” is becoming a poisoned word. Almost meaningless now, basically synonymous with stuff just looking good. Kind of ironic because taste is all about critical thinking. *Why* does this thing look good?.

A lot of young ppl associate “good design” with corporate / big tech. For certain products it’s probably better to make it look kind of DIY. Perfectly Imperfect does this really well

Designers should code. Designers should train models. Designers should know what stack and heap are. Designers should write their own custom non-IEEE floating point representation. Designers should produce tasteful and balanced commentary on the state of high NA EUV lithography.

Spotify’s in-app recommendations experience sucks and is getting worse . - recs are heavily biased towards music you’ve already heard.- hard to steer the algo.- hard to sample lots of songs quickly.

Sad to see @Spotify basically deprecating their entire web API. I’ve been trying to get this app pushed through for a rate limit increase for almost 6 months now. Was just denied again a week ago, seems like this is why. App is now broken even for me. Incredibly sad

iOS 18 is a truly embarrassing software update, and no one should download it. New features have questionable utility or aren’t shipping until months from now, and all your most used system apps (Maps, Photos, Safari) have been completely enshittified.

Allow me to have a brief Nikita Bier moment, need to get this off my chest:. You absolutely do not need more than 1-2 people to build 99.9% of all iOS app MVPs in the year of our lord 2023. Anyone who says otherwise is bad at eng / design / business or all of the above.

Right now Lark is the thing I'm most proud of. There's nothing else like it out there. Originally I planned to try and compile the @rive_app runtime for embedded but it wouldn't fit. The only way to get the behavior I wanted was to write everything from scratch myself.
Lark is a vector graphics & animation engine / editor written from scratch specifically for embedded microcontrollers. We use it in-house to create all the animations for LITTLE GUY. All animations are vector and render in real-time on the device. ➡️

Hey man did you hear that artists aren’t designers. Bro engineers are artist. Actually designers can’t do art in 2025. Artists can do design though. Art is the manipulation of design. Design is just the art of markets bro. I often think about how engineering is the market of de.

.@FocusState is a needlessly tedious abstraction in SwiftUI. Annoying for many reasons:. * not interoperable with @Binding.* can't use in view models.* difficult to pass between views.* slightly diff behavior from @Binding – updating in ancestor views does not propagate up to

This mf is calculating inverse square root with a lookup table 🤣🫵 he doesn’t even realize you can bitshift the binary representation, subtract that from 0x5F3759DF then run a single iteration of Newton’s method to yield a more precise approximation 😂😭.
