Excited to announce my new course on Dometrain - Solution Architecture Deep Dive. The #1 feedback I got on the first course was the depth. Don't worry, this ones goes deeper. Deeper into what it actually means to be an architect in 2025. #dotnet dometrain.com/course/deep-...

6 weeks ago, I published my Getting Started: #Rust course on Dometrain. The reviews have been fantastic! That said it's by no means possible to cover a language as cool as Rust in a single course, so I've followed that up going a layer deeper. DHH would be proud. dometrain.com/course/deep-...

We’ve got to build it before China does.

If you're building a modern application, chances are you need to think about identity Sometimes, you even need to give your machines identities so they can login. What's the smartest way to manage that in 2026? Come find out with @scottgerring.com and me. youtu.be/qwuLB44RMrk #softwaredevelopment

If an LLM is writing all your code now, why not pick a language that is performant, safe and sustainable. A language that empowers everyone to build reliable and efficient software. And then when it does inevitably break, or go wrong, you can pickup my course on Dometrain. #rust #programming

Is there anyone in my network running production applications on @vercel.com ? And if so, could you spare me 15 minutes to chat about how you're using it? How you think about architecting applications on the Vercel platform and any challenges you see. #serverless #vercel #developers

Storytelling is such a HUGE part of creating content for me, whether it's conference talks or videos. I've been playing around the last couple of weeks with taking this to another level with a bit of hand drawn animations. #architecture #systemsdesign #animations #storytelling

Serverless! What does it even mean anymore? Find out with @scottgerring.com and me. youtu.be/CNBbqYwB9Fw

Consistent humanism means opposing the genocide in Gaza, AND antisemitism. It means opposing the US/Israeli invasion of Iran AND the Iranian regime's murder of its own people. It means opposing the US/UK invasion of Iraq AND the Russian invasion of Ukraine. It means confronting violence everywhere.

"The speech today, the agenda the government's got - it doesn't speak to the moment" - @elliechowns.bsky.social Unlike Labour, the Green Party has a clear plan to tackle the issues that people care about: cost of living, wealth inequality and action on the climate and nature emergency.

No one expected Keir Starmer to solve our pressing problems overnight. But what we did expect – and had every right to expect – was that he would lay out a clear vision and roadmap for doing so. Instead, we’ve had drift, appeasement and a startling absence of ideas, values and ambition. 🧵1/6

Serverless ❤️ OpenTelemetry - Better Together Just because you're building serverless applications doesn't mean you can't get value from OpenTelemetry. In fact, I'd recommend it. Find out how in this weeks video. #serverless #opentelemetry #dotnet youtu.be/y4517SxUH_s

Your Guide to Simple, Evolvable Software in Event-Driven Systems is here! In this video, Scott and me talk about how to write cleaner, more evolvable code if you're building an application that needs to process messages from a queue, topic or bus. #software #architecture youtu.be/UBhxmVU70j0

Ergodicity - a word that sounds complicated but is vitally important not only for software architecture but also for day to day life. Recently I took a deep dive into the concept, and threw together some notes. blog.jameseastham.co.uk/blog/2026-04...

Yep Mythos is definitely such a powerful tool. I believe you @anthropic.com . A curious decision to not use it on your own systems, but I'm sure you know what you are doing and we can believe every word you say. www.bloomberg.com/news/article...

Every time I hear an exec of a tech company, an AI company, or some billionaire talk about how AI is going to change industry X it makes me sad. Obviously the idea of not having to pay people makes you want that outcome. Yet sometimes I feel like there's only a subset of the world who sees it 🤷🏻

Also, how you can trust a thing that hallucinates (no matter how little) is beyond me

This 💯

It doesn't need to be this way. The Green Party are the alternative. Check us out in this weeks New Statesman and: Join.greenparty.org.uk

“I’m done ceding my brain — the core of all that makes me who I am — to the financial interests of a small number of technology billionaires or the shortsighted conveniences of hyperactive communication styles,” Cal Newport absolutely on the money! calnewport.com/in-defense-o...

And that's a big hard nope from me. I was already on the 'avoid the US bandwagon'. Not a change I want a non deterministic, hallucinating anywhere near landing planes full of hundreds of people thanks.

I'm sorry but I really struggle to understand shit like this. Amazon invest in Anthropic who agree to buy Amazon chips. It's all feels very you scratch my back I'll scratch yours to make all of our numbers look better. Shareholder value at all costs right! As long as the line goes up all is good.

The post-AI-bubble regulation should start by making it illegal to do circular deals - money invested cannot be used to pay for services, money invested cannot be used for buying hardware, etc, etc. Hell, I'm game for making it illegal to invest in customers at all.

Microsoft: "We are adding Copilot AI to all our products, and if that means building datacenters that will consume more power than a small city, that's the price we all have to pay." Also Microsoft: "Whoa there skippy! Showing SECONDS in your system tray clock uses more power! You sure about this?"

So what they're saying is they can be automated and should be let go for cost efficiencies.

How often have you joined a new team or worked with someone more experienced and they've said "Just use a ......" Just use a queue. Just use an outbox. Oh, for that you just need to use the saga pattern. Fear not, I've got your back. Packaged up as a nice interactive website. justuseaqueue.com

Sorry, you’re telling me that something that doesn’t feel pain, doesn’t have lactic acid build up, doesn’t need adequate hydration or electrolytes, doesn’t need to pee, and doesn’t get tired is only 6 minutes faster than humans? you’ve fucked up a perfectly good Roomba.

@scottgerring.com and me chat a lot about code quality, code structure, and generally the 'craft' of software development. Which you could argue might be being lost a little bit... But once you've got that beautiful piece of software, how do you actually ship it somewhere? youtu.be/73u4boYBcGM

Spending millions on platform engineering is not innovation. It's not human-centric. And it's definitely not solving the problems your users actually have. Design thinking has a principle: focus on verbs, not nouns. Don't ask "how do we build better infrastructure?" Ask, "how might we enhance a d

Happy Tax Day, New York. We’re taxing the rich.

One of the unexpected benefits of buying an electric vehicle is it has gamified 'good' driving. Predicting what's happening upfront, slow steady acceleration, regenerative breaking to slow down. I saw my remaining mileage tick upwards today, not down.

Good design thinking starts with a story, not a solution. "At the heart of any good story is a central narrative about the way an idea satisfies a need in some powerful way." blog.jameseastham.co.uk/blog/2026-04...

Rory Mcllory is 90th out of 91st in terms of fairways hit in #TheMasters yet is 6 shots clear. I've just finished reading a book about the value of the short game... This is pretty convincing evidence. ⛳

In my latest online course, I cover the fundamental integration patterns you will see most often in #serverless applications.. And this isn't just point to point vs pub/sub. This course covers a range of different #patterns, and importantly, how you can actually use these patterns in #production.

Movements to shut down or ban data centers are amassing power and notching victories. Wikipedia has banned AI-generated content in articles. Publishers and entertainment studios are being pushed to reject AI-produced content outright. In other words: It's open season for refusing AI.

Ever had a green CI/CD pipeline but your Lambda deploy is actually broken? Tests passed, but a configuration mistake means prod is dead. In this video you'll learn how to use Lambda Aliases/Versions & AWS Code Deploy to safely rollout new features youtu.be/gsLkVmkkOxc #serverless #aws #dotnet

The key to life is to approach every single person with expectation. Not cynicism, not anger, not division or biases. Approach every person with the expectation that they are good people who are full of love. Rowan Williams (slightly paraphrased) in this morning's Easter service.
