Why is it that LLMs say, “You’re absolutely right! “ so often? I don’t mean why are they so annoyingly obsequious. I mean why that exact phrase, nearly every time, from all the vendors? From all I know of LLMs, it doesn’t make sense that they’d ever be so predictable. 🤔

Can we start referring to him as The Andrew Formerly Known As Prince?

How do you profile and observe your production software, regardless of language and tools, across all your machines? Mohammed Aboullaite joins me this week to dive into the Linux kernel, explaining how eBPF can profile and monitor software from the very root of the stack. youtu.be/sgzTo4dRU3w

Have you ever been frustrated by a git merge? That’s a trick question - of course you have. 😁 This week we’re talking about a tool that’s git-compatible, but completely rethinks the way we handle merging, rebasing and undo/redo: youtu.be/ulJ_Pw8qqsE

I’ll be spending the rest of the week enjoying the aofo! conference in Copenhagen. 😁 If you’re there, come say hi. 😀 #GOTOcph

It’s really surprising how often Gemini CLI will just stop. Just stop dead, like it’s dropped a message in transit and there’s no check-and-recover code. Come on Google, you’re suppose to be good at this. 🫠

This is the coolest thing I've seen in a long while: www.lego.com/en-gb/produc...

I take great pride in devising the intros for my podcast, but this is the first time one's been turned into a heavy metal logo. Love it! 😍

How do you test software, if you want to be *really* thorough about it? To answer that question this week we're going as far back as the 8-Bit Nintendo, as far down as the CPU, and nearly as far up and away as Mars. Will Wilson joins me to explore how far you can push testing… youtu.be/_xJ4maWhSNU

Plenty of people complain about AWS' complexity, but could you build anything simpler, when every user wants something different? I'm joined this week by Anurag Goel to discuss the many challenges of building a hosting platform, including scaling to 100bn requests per month! 😱 youtu.be/SLDMHLImEys

Today I tried bodyboarding for the first time. It’s rather like being so drunk you try to sleep on the dinner table.

It’s a very short journey from loading PNGs onto a bird to carrier pigeons that can rickroll you over long distances.

How hard is it to write a billion-row-per-day database? Hard enough that its evolution has taken Paul Dix on a heck of a journey over the past ten years, figuring out everything from Time-Structured Merge trees to Go vs Rust to getting pricing models right the hard way: youtu.be/r4LkaPkxang

It’s July and I’ve just received a Christmas marketing email. #newpb

You know you've asked a good question when the guest makes this sound... 😁 (If you want to know what Paul's is about to explain, you'll have to tune in in a couple of weeks.)

Working on a new talk. I think this slide is going to be a banger.

Going beyond the hype of AI, and avoiding the cynicism, how is AI going to change the way we code? Zach Lloyd joins me with his bet on what agentic tools might actually look like, and how the terminal is the perfect jumping-off point: youtu.be/cwOrpH8feco

Amazon really put an astonishing amount of time and money into trying to make, "25% off toothbrushes and battery packs," into a national holiday. 😅 #primeday 🤷‍♂️

It's always fascinating when someone's really trying to get to the root of the problem, and Marty Pitt is trying to get to the root of a $500bn problem - systems integration. This week we're exploring TaxiQL, a system that goes beyond endpoints to look at data's very meaning… youtu.be/hXjnbehvDiQ

If you're using #Claude code a lot & you're using it in multiple tabs at once, you're probably hitting the same problem I am: tracking down which sessions are blocked waiting for user input. If so please take a look at this issue. I think it's solvable with a small change: github.com/anthropics/c...

Wow, I've just tried Google's Gemini CLI and it is a note-for-note copy of Anthropic's Claude Code. Brace yourselves for a massive lawsuit...

I'm on a big #ClaudeCode kick this week. This interchange felt really sci-fi to me: "I don't have enough information to answer that question." "Well, make a tool to get it!"

Bugs are an inevitable fact of producing software, so sometimes the best you can do is find them as fast as possible. This week on Developer Voices, Isaac Van Doren joins me to talk about bug-hunting techniques, from assertions & types, to making the most of Roc, Zig & SQL. youtu.be/VxD1rvEymAI

Config files work great for simple examples and docs, but real builds always get messier. Whether it's a build or devops infrastructure, eventually you outgrow static configs. Then the question becomes: do you have a proper programming language, or some unholy abomination like YAML with for loops?

If anyone is hiring, I'm still looking for my next thing. Senior Frontend Developer. Skilled at HTML/CSS/JavaScript, React, UI/UX, A11Y, web performance, design systems, Web Components, and more. I'd love to work with you! gomakethings.com/resume

It's a shame the term "Vibe Coding" got big and triggered a wave of hype & counter-cynicism. It's just muddied the water for where the serious value is... blog.jenkster.com/2025/06/dele...

Genie: You have 3 wishes. Me: I wish that after every wish, you flipped between binary and denary. Genie: You have 10 wishes left. Me: I wish for a million dollars. Genie: You have 9 wishes left. Me: I wish I could fly. Genie: You have 1000 wishes left...

I've been experimenting with Claude Code a lot this past week. I think you'll agree, I've nailed the fine art of prompting.

What’s the difference between SSDs and Object Storage? Latency, redundancy and $$$$! Plus a lot of deeply technical work if you want the flexibility to choose. This week I’m joined by Filip & Josep of Aiven, talking about adapting #ApacheKafka to write straight to S3: youtu.be/q4msyXtRuDk

Microreview of the latest Mission Impossible movie: it’s a completely different vibe, and it’s bad for completely different reasons, but that’s the worst film I’ve seen since George Clooney was Batman. 😂😭🤦🏻‍♂️

The genius of Monty Python's "Argument" sketch is that they managed to write a character that automatically says the opposite of everything you say, long before any of the Pythons had a teenage son to deal with. 😭

Has there ever been a greater comeback in programming than what’s happening with the #JVM lately? From concurrency to high performance computing to LLMs, Josh Long joins me to go through everything you’ve missed in #Java’s evolution: youtu.be/rNJs9ZX7-Lw

Did you know that the BBC serves almost all of its web traffic using @elixirlang.bsky.social ? #elixirlang

I'm building something at the moment that's all about taking a task that's possible-but-painful and making it trivial. While I beaver away on the code, here's the pearl of wisdom that informs the design. Let's call it The Seventh Law of Developer Experience. blog.jenkster.com/2025/05/tust...

What's going on with #ApacheKafka and the data streaming world? Where does it shine, and where are the edges still rough? This week I'm joined by the co-author of Apache Kafka in Action to look at the state of one of my favourite datab-...I mean, data-handling systems: 😅 youtu.be/lSmYyuvSaA0

Just 11 days until the inaugural Code Remix Summit in sunny Florida!☀️ 🎟️ The event is almost sold out, so don’t wait to grab your pass: coderemix.ai

Your top priority on any todo list should be, "Build a portable, low-cost nuclear fusion generator." You will be amazed what you can achieve while you're procrastinating on that one. I just answered five(!) emails. Follow for more genius life hacks, etc...

Huge thanks to @krisajenkins.bsky.social for the wonderful discussion about @apachedatafusion.bsky.social on Developer Voices: pod.link/developer-vo.... Kris's smooth voice and wide ranging knowledge made it most pleasurable.

In this week's Developer Voices, Andrew Lamb takes us through #ApacheDataFusion, exploring how this Rust toolkit shaves years off the prospect of creating a custom database. Fascinating stuff for any data and architecture fans like me. 😁 youtu.be/8QNNCr8WfDM

@krisajenkins.bsky.social recently released a podcast episode with a couple of people from JupyterLab, about their real time collaboration framework for rich applications like GIS and CAD. blog.jupyter.org/real-time-co...

One of my favourite conferences is looking for podcasters to be part of their next event, so if you know any good tech podcasters - any at all - absolutely anyone with a good tech podcast you’d recommend - let them know, okay? 😁

OH: Vibe Coding will do for programming what MySpace did for graphic design.

It’s my birthday, so to celebrate I’m diving in to the internals of how Jupyter works. 😁 This is a dive into the architecture and future of one of programming’s most popular tools. youtu.be/_-zhMzwpSOQ

I really enjoyed this conversation especially Diana's takes on addressing eventual consistency "can't solve doubts with more words" and the traditional architect glue approach of solving systemic pain by sticking trendy tech solutions together without addressing the business needs first.

If I were Liz Truss I'd be on Wikipedia right now, changing my entry to read, "*second largest* financial crisis in modern times."

Diana Montalion's a joy to talk with. I was very lucky to get to pick her brains at GOTO, diving into how we design better systems of software and systems of people. 🙂

Hey look who featured in ThoughtWorks’ tech radar! www.thoughtworks.com/radar/langua...

This week on Developer Voices we’ll be taking a look at Welsh Assembly. It’s an innovative spin on machine code that features instructions like lload, extra-llong integers, and a unique approach to register overflow that works by carrying a rare bit.

“It works on my machine!” If you’ve ever uttered those words, then come & learn about Nix. Julian Arni joins me this week to discuss the tool that attempts to solve the problem of reproducible builds once and for all... youtu.be/maw2hptpErI

There's something about #Rust execution model I clearly don't understand. Help me out Rust people - why does this test case pass if I wrap some code in an `if true` block, and fail if I don't?? 😵‍💫 (rustc 1.8.2. Source here: github.com/krisajenkins...)
