Start imperfectly. A bad app that exists can be improved. A perfect app that was never started is worthless.

Vibe coding is basically vibe driving:

An autonomous car takes you somewhere and for a second you think, Nice, I’m making progress.

But you’re not the driver — which means you’re not a coder.

Which is why “vibe coding” is a perfect little #oxymoron.

Do we have archives relating to your history? Probably! Our archive reflects global histories & is open to all. Conservator Shabnam Balouch has helped uncover our Persian archive, and you can find out more at an upcoming talk & our free public workshops in January! #EYAYourArchives #KewLA

For anyone currently working on Project 2 of #100DaysOfSwiftUI by @twostraws.bsky.social, I recommend #FlagKit — a collection of 255 flags available in both PNG and SVG.

For #EYAAnniversaries, we delved into collections on our Millennium Seed Bank, which opened at Wakehurst 25 years ago. Among the reports & articles on the development of one of the world’s largest seed banks, we discovered publicity materials featuring none other than Sir David Attenborough! #KewLA

Made a unit converter that also measures your caffeine needs. ☕️📱

Did you know botanist Sir Joseph Hooker travelled with two Bhotea mastiff dogs? Today’s featured image for #ExploreYourArchive Week #EYAPets is a playful drawing from his letters, showing Kinchin the dog being ‘taught’ to write.

What #EYABeauty lies on the inside of this unassuming folder? We're showing off Elsie Wakefield's fungi illustrations today 🍄 Wakefield became Head of Mycology at Kew Gardens in 1915 and our Archives hold her personal papers collection, which includes letters, illustrations and photographs. #KewLA

Plant taxonomy is disappearing - and so is our ability to protect species 🍂

Nearly half of countries have fewer than 10 plant taxonomists. Kew is working to close the gap, but we need more experts fast.

Read the study’s key findings and what we're doing about it 👇

There’s friends, best friends, and then there’s the mutualistic relationship between the hornbill and the mongoose. See this peculiar pair in action in this week’s Surprising Science 🐾🪽

🧠 Hot take on 100 Days Of #SwiftUI:

Is the Schrödinger's Cat analogy for #Swift optionals actually flawed? 🐱📦

Schrödinger implies superposition. A Swift #Optional is never nil and value at the same time — It's a mystery box, not quantum physics.

Am I overthinking this? 😅 @twostraws.bsky.social

🎉 Finished Day 13 of the #100DaysOfSwiftUI ! www.hackingwithswift.com/100/swiftui/13

@twostraws.bsky.social

Protocol extensions were a curveball at first — defining signatures in the protocol vs functionality in the extension!
