Jun 08 @Shreyassanthu77 Combo of - Stripping back all unnecessary complexity - Playbooks for everything - AI code review with super specific instructions & knowledge of our patterns. Means this can be instituted without having to have this kind of dev on the team full time 1 0 0 0 272 .

Jun 08 @hunvreus Sorry brain fart - I thought you were implying the library authoring step itself was no build, which was how I approached it with base styles - but this meant not using tailwind classes. 0 0 0 0 196 .
Jun 08 "In less than 15 minutes, I had a full app up and running with auth, database, email, styled and deployed!" 3 0 1 324 107 .
Jun 08 @hunvreus How are you handling the "no build" part with Tailwind? Are you manually converting all the properties? 0 0 0 0 113 .

Jun 05 It's a shame that crypto earned itself such a terrible reputation - I'm not a crypto fanboi by any means, but I do think this use case (usdc transfers for ~free) is still being slept on because people think crypto=bad 2 0 2 345 217 .
Jun 05 @hunvreus Think I saw it on Twitter but can’t find it, sorry! 0 0 0 0 61 .
Jun 04 Disclaimer: These numbers came from Claude and may be wrong. Would love for someone from @stripe to correct them if they are. Report here: https://t.co/8gzlOzPinB 0 0 0 106 162 .
Jun 04 Bottom line: Every 10 basis points Stripe could reduce fees would unlock $140-200B in additional global commerce. The current pricing extracts maximum rent but leaves trillions in economic value on the table. Transaction costs really do matter at scale. 6/6 1 0 1 112 257 .
Jun 04 This is a classic welfare economics problem: Stripe's private optimization (maximize revenue) diverges from social optimization (maximize total economic activity). Payment processors sit at a unique chokepoint in the global economy. 5/6 0 0 0 0 236 .
Jun 04 Economic modeling suggests optimal fees around 1.8-2.1% would: ✅ Give Stripe healthy 12-18% margins ✅ Increase global transaction volumes 40-80% ✅ Improve total economic welfare by $800B-1.2T annually 4/6 0 0 1 37 204 .
Jun 04 Current 2.9% fees break down roughly as: ~1.0% operational costs (infrastructure, fraud, compliance) + ~1.9% economic rent for investors. That 1.9% "excess" is where the efficiency loss happens, based on payment elasticity research. 3/6 0 0 1 46 236 .
Jun 04 The core trade-off: For every basis point (0.01%) Stripe charges above operational costs, the global economy loses ~$14-20B in transaction volume. Each marginal dollar to Stripe equity holders reduces global economic activity by $4,000-6,000. 2/6 0 0 0 0 246 .
Jun 04 Might fuck around and have Claude write this research as a tweet storm 0 0 0 471 70 .
Jun 04 There is an inverse relationship between the success of companies whose business model is transaction costs (e.g. @stripe), and the "GDP of the internet". Stripe were the good guys in papering over a legacy system, but as new systems become possible, @stripe must choose between their actual stated goal - "Maximising the GDP of the internet", and Maximising Good 'Ol Shareholder Value - these incentives now are now fundamentally misaligned. 1 0 0 359 444 .
Jun 04 There's something so funny to me about getting out of your supercar to walk into Google HQ for a day full of scheduled meetings 😂 0 0 0 244 129 .
Jun 04 People still asking me "How do you not think LLMs are reasoning?" CSS is one example - Jhey publishes a lot of really cool CSS examples - often based on new CSS features that are documented but where there's not a lot of examples. So - things that a human can figure out by reasoning. Even the top, most recent LLMs just, don't work for this. 4 0 1 374 343 .
Jun 03 This is a remarkably good piece of writing, and should become part of the canon for any startup that values taste 1 0 0 237 113 .

Jun 02 @bradleymeck @AdamRackis That's fair Bradley. Not supporting typescript is a tradeoff - although I don't think "think about all the ways a variable could be used" is an issue for a lot of teams. And the key disagreement I have is the assertion that you can build "software at scale" without a build step. 0 0 0 0 304 .
Jun 01 @AdamRackis If you think you need more context, perhaps refrain from the numerous insults you’re levelling. You are going to come out looking quite dumb at some point in the future. 4 0 0 0 182 .

Jun 01 @AdamRackis I am the employer. I got serious about simplifying things because I was sick of paying people like you ridiculous salaries to build incredibly basic software, and preserve the complexity that justifies their salaries. 3 0 0 0 229 .
Jun 01 @AdamRackis Ayyy more attempts to make people seem small. If you ever decide to engage on the merits I’m here. 0 0 0 0 111 .
Jun 01 @AdamRackis I’ve noticed a lot of your tweets try to make other people seem smaller so that you can feel bigger. “Most of us are busy doing *important* things” Also, you seem to be back pedaling? “Only works for splash pages”, “no it works for production”, “ok, but hAve yOu gOt a real Job?” 5 0 0 0 292 .
Jun 01 We started an experiment a year ago to build our React Native apps with a hybrid approach (stacked webviews that feel native), with some screens built in React Native where necessary. With the exception of chat UI - which is still hard to do with a webview because of keyboard UX - the screens we've built in html have been 1) Much easier to test (pull to refresh), 2) Much easier to implement simple state and navigation, 3) Much less prone to break, 4) Oddly more performant and less likely to drop frames - and we use Lottie to make things feel native. It's taken us a lot of iterations, but I genuinely think we've stumbled on something game changing with this approach - the big downside is the offline experience isn't great. But in almost every other area this approach wins. 3 0 1 368 785 .

Jun 01 This person hasn’t seen preact standalone yet, have they 1 0 0 280 56 .
May 31 Most companies don’t want you doing important things with their API and circumventing their UI, for various competitive reasons As agents become a thing, there will be more and more tension between these competing priorities, and my hunch is the consumer will probably lose. 3 0 0 223 276 .
May 31 He’s right. Remember the decades before typescript when there was nulls in products everywhere. Chaos! 0 0 0 206 102 .
May 31 We’ve done a lot more mobile dev in the last year and my biggest surprise has been that simply learning the core primitives doesn’t get you to “can build polished products out of the box” - I thought that’s what native dev had over the web, but it turns out it’s not true. 5 0 1 491 272 .

May 30 @joshmanders What do you see as being the important differences between “react without rsc”, and preact standalone? 0 0 0 0 115 .
May 30 This is interesting. But if there's only marginal difference, shouldn't you do the one that builds the most goodwill and exposes most people to the product? 0 1 0 175 156 .
May 30 Using AI for non trivial long running work follows a similar graph to the Gartner hype cycle But you have to actually use it for hours a day, for a sustained period to internalise that. This might explain why CEOs of larger companies (including the AI cos themselves) are so hyperbolic - they’re not using it first hand for long enough to see it’s imperfections, and they’re drowning in the noise from all the people who are atop the peak of inflated expectations, and assuming they’re at the bottom of a hockey stick. 3 0 0 195 520 .
May 30 @foragemail it all started great but now I'm getting way too many emails into my main inbox during the day - have my preferences saved like this, and every time I remove the "Inbox" tag but they're still coming. How can i fix? https://t.co/OXAfVEaEWJ 0 0 0 0 250 .

May 28 What’s going on with Nikita? I know he doesn’t think these coins are the same thing as issuing shares. So why is he risking his reputation on this? Has he explained somewhere how this is different to all of the other similar crypto products that devolved into meme coins? 0 0 0 132 272 .
May 28 Yup 0 0 0 128 3 .
May 28 @specialCaseDev Oooh I like this 1 0 0 0 32 .
May 28 The key to building something *really* polished is the period after the "designs have been implemented" where the engineers, pms, designers do hundreds of use-tweak-test loops, see how it *feels*, and keep iterating til the end to end experience feels right. You can tell by using their products that Google just doesn't do this - it's ticket driven development - if it can't be described and added as a ticket, then it won't be done. 2 0 1 272 436 .
May 27 For a long time there haven’t been great examples to point to for “What are some html first apps that feel as polished/slick as Js SPAs” but Ronan’s stuff definitely hits that bar. So nice 2 0 1 306 188 .

May 26 Hot take: if you play this at full speed, it’s actually a slower and less fun way to build web software I actually do believe in voice to code, but this start/stop, slow iteration speed isn’t there yet 1 0 1 268 202 .

May 21 I absolutely loathe bureaucracy and regulation, but I share the view that thinking that’s what’s behind the EU/US divide is incorrect. In the US, there is a pervasive desire for more-and-better, coupled with the absence of shame and cynicism (and then the obvious head start/rich-get-richer, network effects that compound that). It’s not the one-true-way - both have benefits and trade offs, and I like the European way. But you don’t get US level wealth by simply removing over regulation and keeping the culture the same. 4 0 0 427 525 .

May 19 In 2025, the top open source browser agent can still only reliably complete tasks 30% of the time. To replace real employees, this will need to get closer to 100%.
