#GOTOpodcast, @icooper.bsky.social, @davidwhitney.co.uk & Hannes Lowette talk about how architecture really works at scale: • sustainable vs “slash-and-burn” systems • emergent design vs intentional design • why cargo-cult patterns hurt more than they help 🎧 gotopia.tech/podcas

I'll happily recommend this podcast from .NET Rocks w/ @hanneslowette.net explaining Event Sourcing. Thought this was a good rundown of strengths and unfortunately real challenges: www.dotnetrocks.com/details/1961

I keep seeing developers make the same mistakes over and over again. When you want to level up your impact, and thus your pay, only focusing on your tech skills doesn't get you there. Everyone who only focuses only on the tech, plateaus pretty early into their career.

I loved chatting to Flavia about the way they transformed their support organization!

GOTO Conferences@gotocon.com · last yr.

Support got messy as FundApps scaled fast. Flavia Circiumaru tells @hanneslowette.net how they built a 3-desk system aiming to engineer support teams out of existence. youtu.be/Uk9CwG9a_C4?...

I had a chat with my friend @eli.holderness.dev about the cool stuff they do at OpenSAFELY. Be a fly on the wall for that chat, and take a look at this.

GOTO Conferences@gotocon.com · last yr.

OpenSAFELY is revolutionizing medical research by protecting patient privacy and unlocking insights from healthcare data. @hanneslowette.net talks to @eli.holderness.dev about its secure, reproducible approach to research.

"It's just perfect for immediate use!" That's what our students say about our OpenTelemetry in .NET course. Stop wondering how to implement modern observability - start building it today with 40% OFF!

God I love the layout of the Suzuka circuit. What a great technical track. So many places to make a difference. #F1qualifying

Marten just crossed 10 million downloads!

My friend @rendle.dev gave a fantastic keynote at NDC London. They used their amazing sense of humour to drop some serious real talk about feeling like an imposter. I may have shed a tear when I was sitting there watching this. Many people needed to hear this! www.youtube.com/watch?v=fL2p...

I really enjoyed this conversation I had with the fantastic @maritvandijk.bsky.social about reading code. She talks about why reading code is hard, how to get better at it, and where tooling may help alleviate things. Thanks to @gotocon.com for recording and sharing this!

This is Marco Rubio explaining how the USA promised to defend Ukraine forever if they got rid of their nuclear arsenal left after the Soviet Union fell. This is why lil marco was sinking into the couch. He was hoping we wouldn’t find it…so don’t RT right now this very second.

Fuck everything about this news: unisa.edu.au/media-centre... We are creating a society where otherwise beautiful women feel the need to alter their appearance to adhere to an ideal that only a very small portion of men find attractive. We need to fight this. Hard.

Swipe, style, surgery: why dating apps are fuelling cosmetic procedures

They’re the modern way to find love according to the 323 million people who use them worldwide, but dating apps are fuelling an obsession with cosmetic surgery.

@rendle.dev making real talk very funny as the #NDCLondon locknote. Next level!

LinkedIn is losing it. They are using AI-generated fake profiles to push ads, disguised as direct messages into the inboxes of everyone... including paying customers like myself who already pay ~$600/year for LinkedIn Premium. What a low. (This is real, from my "inbox")

@rendle.dev reading an NSFW children story (don’t ask how that works) at the @ndcconferences.com Christmas story. 2 minutes in, and I’m already dying.

@andersnoras.com at the @ndcconferences.com Christmas party: viruses were great until ransomware took the fun out of them entirely. If that makes you filled with FOMO, good. You should be here next year.

It’s december and everyone is starting to post their year in review, or is setting goals for the next year. Since 2024 has been thoroughly crap, and I’m gonna take 2025 slower, I don’t feel like doing either. So… let’s talk about music. Tell me about 6 albums from the past year.

This morning we announced my new gig as CEO and Founder of Zure UK. I'm really excited by the challenge of building something new. zure.com/blog/zure-uk...

. @noopman.com is talking about how we need to do cloud better at @cloudbrew.be. The average cloud project isn’t what is was meant to be. Sounds like ‘doing cloud right’ is actually a lot of work. Is that what the cloud promised us?

Belgian TV personality crashes his Porsche against a roadworks vehicle, at 1AM, on a night where there’s footage of him being visibly drunk in a bar. Luckily injuring only himself. This is someone who earns more than €500k per year, and refuses to take a €15 taxi. Inexplicable. Inexcusable.
