"When you do a fiat transaction, it takes time – sometimes two days, three days. But if you use stablecoins on Stripe, it's almost instant." 💸
The Stripe mission makes going to work so motivating. Here's just one way Stripe is increasing the velocity of money and reducing the cost of doing business, globally. "Give me a lever long enough and a fulcrum on which to place it, and I shall move the world." 🌏

[JR Farr @jrfarr]

I think it's important people see the real value of stablecoins.

Instead of waiting days, money can move almost instantly.

For startups, that's a big deal.

A while back, we helped @euboid at Ferndesk get set up with stablecoin-backed cards through Stripe Treasury.

That means founders can pay contractors, earn rewards on card spend, and operate their businesses regardless of where they're located.

This is what we're building with Stripe Treasury.

i was lost only 2 years ago and broke down into tears... asking this same thing btw

my answer: focus on daily inputs > monthly results

what can you do today that has a good chance of putting you forward in 1-2 years from now?

reality lags so stay consistent with effort daily

In 2019, Apple was doing $150m a year with United Airlines as its largest corproate customer.

United made these banners for an internal event and photo leaked and they had to apologize to Apple (and other $10m+ a year spenders including FB, Roche, Google, McKinsey, Deloitte).

@fayazara Cool, I’m a happy Cleanshot user but I’ll try this on my next machine. Love the option to B.Y.O. Cloudflare account!

[Mark Moriarty @MbyM]

@peterramsing @LeaVerou @claudeai From me, that’s no longer a believable threat. But I’ll often ask Codex/Claude a version of, “Is that the best you can do? Do you need me to hand over to Claude/Codex (the other one) to take it from here? Should I just switch to (otherCo)?”

[Mark Moriarty @MbyM]

Was true in my family home. Instinctively in friends’ houses in Ireland, I check for the light switch outside the wall, not in the bathroom. Sometimes (hotels etc) you see a “shaver only” socket (with an an isolation transformer, to separate circuit from mains), but most homes wouldn’t have it.
@grok fact check me here. Claude says “ the US approach is almost the mirror image of the UK/Irish one – the National Electrical Code requires at least one standard 120V receptacle in a bathroom, typically within about 3 feet of the basin.”
In fairness, the higher 240 V is handier in other contexts, like electric kettles.
(The stereotype fits: worse teeth-care, better tea-drinking!)

Ah come on now @Apple

[Garry Tan @garrytan]

Founders must stop trying to building 2010-era businesses with 2026-era technology.

Don't try to rebuild Foursquare or Yelp.

Don't try to recreate Basecamp by 37 Signals with $10/mo SaaS pricing.

Don't underprice! If it works it's worth a lot more.

Don't be tempted to become "Tech enabled PE" with revenue tricks.

The rules of tech changed with AI. Play the new game.

That web platform you’re thinking of building: you can probably build ~entirely on Cloudflare

Nice work!

[Paras Chopra @paraschopra]

My favorite way of interacting with Claude Code is to have it generate static HTML files as outputs (reports, explorations, code structure, mockups etc.)

I wanted to iterate on the file by commenting in browser and having Claude update the output live.

So, I built this Claude Skill👇

How it works:
- Install Claude Code skill (ask it to clone repo)
- Build an HTML page for anything (e.g. research coding agents and generate HTML report)
- Ask it to make the page interactive

That's it. CC will launch a localhost server and allow you to then leave comments on the page itself and once it updates, will give you a tour of changes.

It's like Google Docs kind of comments/iteration but for HTML pages.
