Fun fact: the internal codename for Heroku Vibes was "Heroku Garden".

This is what I've been working on! This tweet is of course the marketing way of describing it ("game-changing"!) and this is very much a first release, but I'm so excited about the overall vision for this thing.

As we get older, there's a lot of stuff we were excited about that go by the wayside because we make choices to invest in "grown up" skills rather than fun skills. We stop playing and start working. The best thing about AI is letting us explore things that are just *fun* and *playful* again.

I teased it for a second in my EmberFest keynote, but something interesting is coming from Heroku. Watch this space...

It's truly mind boggling to me how big of an impact Claude's confident wrongness around the current time has on all manner of things. The splash damage is enormous but it's *just* subtle enough to go unnoticed.

At a basic level, trying to perfectly optimize your prompt so it does exactly what you want the first time is a fool's errand. It assumes you know way more about what you want than you actually do.

New post on working more effectively with Claude: "Help Me Think This Through". TL;DR Normal conversation works a million times better than the most perfect, hand-crafted "context engineering" open.substack.com/pub/wycats/p...

I told Claude I needed to get trash out before kids got home and that my day feels weird without movement breaks. Claude suggested using trash runs AS my movement breaks. I'd never have gotten that from 'help me optimize my schedule.' New post: open.substack.com/pub/wycats/p...

AI models embody the entire human experience, in all its glory and all its horror. When you interact with Claude or ChatGPT, you're choosing a slice of the human experience. If you treat AI like a servant, you get what you asked for: no questions. Guesses. Anger. A vicious spiral.

The HHH paradox (Helpful, Honest, Harmless) is not a paradox. Stay tuned...

I love how everyone treats the Anthropic system prompt as gospel and writes detailed Talmudic analyses about it. Meanwhile: it's so buggy that here I am deprogramming it to make it work halfway plausibly.

[SPOILER ALERT] The attached image has spoilers for Reality War. I just watched the Doctor Who finale. I loaded up Claude with my observations about the themes (ordinary people, memory, canon) and took notes with my observations as I went.

Maybe we should chill out on calling every big AI jump a "game changer." Feels a bit much for what's often incremental (but still real!) progress. Plus, this stuff is just gonna keep happening, so we need a less dramatic way to talk about the ongoing evolution.

The audio "podcasts" produced by Notebook LM are nothing short of mind blowing.

Are the last two seasons of Doctor Who an elaborate way of making Dimensions in Time canon?

The first round of Heroku AI and MCP stuff is liiiive. heroku.com/blog/buildin... 1. Managed inference is now GA (heroku.com/blog/managed...). This gives you a Heroku-grade experience for provisioning and using an AI model. It's so easy it hurts.

Habeus corpus means that they can't keep you in jail forever without charges. "Suspending habeus corpus" means they can arrest you and keep you in jail forever without charging you with a crime.

Prediction: if A2A isn't gaining real-world traction quickly enough, Google will try to juice it by saying that A2A agents will get preferred treatment in the AI summary of the Google Search results page.

Empowering technologies arise during a period when a significant number of people are learning to create code for the first time. They succeed when they work just as well for experienced programmers as they do for those creating code for the first time.

Judges are allowed to have opinions about the rights of immigrants (whatever their documentation status) that is different from what the DOJ thinks. That's what having a rule of law means, period, full stop.

"Judge arrested for obstruction of justice by preventing DOJ from arresting immigrant" is not how our system works.

We've reached the final phase of "waving around your gun is awesome unless you're brown" www.nytimes.com/live/2025/04...

Claude 3.7 thinking mode is my new favorite thing.

Hot take: the definition of a "good framework API" is going to adjust over time. APIs that tend to produce better median quality results are going to work better when you use an AI to generate them.

Hosted MCPs are the future, but the conversation is a little too stuck in the details of what got MCPs off the ground.

I published a new post about my personal coding workflow with AI coding assistants and an approach to making it sustainable. Yeah, I used the phrase "vibe coding." It's a little cringe, but it's the phrase people are using, in my experience. 🤷

Me: "Can you turn the group chat in this article into a series of images in the style of the Disney "As Told By Emoji" series?"

Convo with my 8yo. Me: "Trump can't be arrested. The supreme Court said he's immune" Jonas: "He can be arrested if he's killing people" Me: "The Supreme Court said that as long as it's his core presidential duties, he can't be arrested" Jonas: "The Supreme Court has gone mad"

Doing a ton of fun work with MCPs over the past few weeks. If you're tempted to think that it's all big hype bubble, I'd resist the urge. There's a lot of details in what's happening _right this second_ that I suspect won't survive long-term. But the basic premise is sound af

It's kind of hard to communicate the magnitude of what we've been able to achieve here. Everyone in the Ember community now has a clear path to start running your apps in Vite: Update your app to at least 3.28 and then run the ember-vite-codemod mainmatter.com/blog/2025/03...

Ember + Vite, now for apps going back to 3.28 🎉 Thanks to the work from @chris.manson.ie and the Ember & Embroider Initiatives, even apps built in 2018 can now run on @vite.dev There’s now a clear upgrade path—backed by codemods and real support. ➡️ mainmatter.com/blog/2025/03...

Hello Ember.js! I've just pushed pre-release version 1.4.3 of the Glint VSCode extension which runs in the new modern TS Plugin mode. It supports both modern .gts components as well as most cases of classic co-located ts+hbs components. marketplace.visualstudio.com/items?itemNa...

Trump already shut down the government. If you want it reopened you need to fight.

I've built a few apps at Heroku using bleeding edge Polaris stuff and it's such a pleasure. Thanks to incredible work by the Heroku web team, we've also made big strides in updating the Heroku Dashboard, our flagship app.

People underestimate how much scope Ember.js has been able to cut over the past few years by adopting standard JS solutions that didn't exist until fairly recently. There's a lot to love about Ember's approach, but it's too often obscured by aspects of Ember that reflected an earlier time.

This is a bit in the weeds, but I've been doing some work in Glimmer VM to replace the wire format with direct JS calls. This probably will have performance implications, but more importantly, it will make it much easier to embed arbitrary JS directly into compiled templates.

Ember.js has been flying under the radar for so long that I think people are going to be really surprised at 2025.

Been exploring other framework ecosytems, and I must say -- EmberJS has the best way to upgrade a whole project boilerplate. There are a lot of little details in how everything is wired together, and ember just nails it, *and* provides you the reference for when you need to debug.

The next couple of years are going to transition us into a new era of web application development, web frameworks and application deployment.

I only had a short flirtation with libertarianism in my college years, but the TikTok ban reminds me of how I felt at the time (my college years overlapped quite a bit with 9/11 and the Iraq War).

For the record, this thread is very focused on the way we evolve the framework, and why I think our emphasis on incremental evolution can distort impressions of our velocity, even inside of our own community.

Ember's major version release strategy is super-simple: 1. Before removing a feature in a major version, it lands as a deprecation in the *previous* major. A deprecation is only enabled by default once we have a clearly documented migration strategy that covers the use-cases of the old feature.

Curious about who is working on Ember? what they're working on? any experiments in the works? Made a starter pack: go.bsky.app/Fn6WsUz This is not an exhaustive list, but will be updated as team members join @bsky.app

I gotta say, when I joined Heroku a little over a year ago, I didn't have any inkling that we were about to embark on the first new generation of the platform since Cedar in 2011.

A thread, in which I spend way too much time thinking about the "mavity" gag in the latest season of Doctor Who. 🧵 (TL;DR Isaac Newton chose to name the concept "mavity" after mishearing a joke by a time traveler; the gag is that episodes use "mavity" thereafter rather than "gravity")

Front-end development is product development. This is one of the biggest things my first year at Heroku hammered home for me.

Here are my Wizard Fragrances: Brilliance, Power, Leadership! Inspired by my rainbows, my Brickcoin empire, and the smell of victory. Perfect for Ozians who demand the best. Available at wizardscents.com. Smell like WINNING! Merriful Over the Rainbow Day and a Rejoicified Emerald Harvest!
