From Unit Tests to Whole Universe Tests (with Will Wilson) 1:12:12

Play Pause

1h ago1:12:12

1:12:12

How confident are you when your test suite goes green? If you're honest, probably not 100% confident - because most bugs come from scenarios we never thought to test. Traditional testing only catches the problems we anticipate, but the 3am pager alerts? Those come from the unexpected interactions, timing issues, and edge cases we never imagined. In…

InfluxDB: The Evolution of a Time Series Database (with Paul Dix) 1:49:23

2M ago1:49:23

1:49:23

How hard is it to write a good database engine? Hard enough that sometimes it takes several versions to get it just right. Paul Dix joins us this week to talk about his journey building InfluxDB, and he's refreshingly frank about what went right, and what went wrong. Sometimes the real database is the knowledge you pick up along the way.... Paul wa…

Beyond AI Hype, What Will Developers Actually Use? (with Zach Lloyd) 1:18:06

2M ago1:18:06

1:18:06

If AI coding tools are here to stay, what form will they take? How will we use them? Will they be just another window in our IDE, will they push their way to the centre of our development experience, displacing the editor? No one knows, but Zach Lloyd is making a very interesting bet with the latest version of Warp. In this deep dive, Zach walks us…

The $500 Billion Integration Problem, And One Possible Solution (with Marty Pitt) 1:31:33

2M ago1:31:33

1:31:33

Ever wondered why data integration is still such a nightmare in 2025? Marty Pitt has built something that might finally solve it. TaxiQL isn't just another query language - it's a semantic layer that lets you query across any system without caring about field names, API differences, or where the data actually lives. Instead of writing endless mappi…

Making Software Crash Before It Breaks (with Isaac Van Doren) 57:08

3M ago57:08

57:08

At 23, Isaac is already jaded about software reliability - and frankly, he's got good reason to be. When your grandmother can't access her medical records because a username change broke the entire system, when bugs routinely make people's lives harder, you start to wonder: why do we just accept that software is broken most of the time? Isaac's ans…

Making Apache Kafka Diskless (with Filip Yonov & Josep Prat) 1:29:29

3M ago1:29:29

1:29:29

How do you retrofit a clustered data-processing system to use cheap commodity storage? That’s the big question in this episode as we look at one of the many attempts to build a version of Kafka that uses object storage services like S3 as its main disk, sacrificing a little latency for cheap, infinitely-scalable disks. There are several companies t…

The State & Future of Apache Kafka (with Anatoly Zelenin) 1:12:22

4M ago1:12:22

1:12:22

I’m joined this week by one of the authors of Apache Kafka In Action, to take a look at the state of Kafka, event systems & stream-processing technology. It’s an approach (and a whole market) that’s had at least a decade to mature, so how has it done? What does Kafka offer to developers and businesses, and which parts do they actually care about? W…

DataFusion - The Database Building Toolkit (with Andrew Lamb) 1:32:10

5M ago1:32:10

1:32:10

Building a database is a serious undertaking. There are just so many parts that you have to implement before you even get to a decent prototype, and so many hours of work before you could begin working on the ideas that would make your database unique. Apache DataFusion is a project that hopes to change all that, but building an extensible, composa…

Jupyter's Architecture Unpacked (with Afshin Darian & Sylvain Corlay) 1:29:11

5M ago1:29:11

1:29:11

Jupyter’s become an incredibly popular programming and data science tool, but how does it actually work? How have they built an interactive language execution engine? And if we understand the architecture, what else could it be used for? Joining me to look inside the Jupyter toolbox are Afshin Darian and Sylvain Corlay, two of Jupyters long-standin…

Graphite: Image Editing as a Syntax Tree (with Keavon Chambers & Dennis Kobert) 1:17:32

6M ago1:17:32

1:17:32

Graphite is a new image editor with an interesting architecture - it’s a classic UI-driven app, an image-manipulation language, and a library of programmable graphics primitives that any Rust coder could use, extend or add to. The result is something that you can use like Photoshop or Inkscape, or make use of in batch pipelines, a bit like ImageMag…

ReScript: A Better Typed JavaScript? (with Gabriel Nordeborn) 1:32:53

7M ago1:32:53

1:32:53

ReScript is a strongly-typed programming language that compiles to JavaScript, and that puts it squarely in competition with TypeScript. So why would a JavaScript developer choose to learn it next? What does it offer that makes it a tempting proposition? And how are the ReScript developers making life easier for anyone who wants to make the switch?…

A universal query engine in Rust (with Predrag Gruevski) 1:15:31

7M ago1:15:31

1:15:31

Trustfall is a library based on a simple question - what happens if we can query absolutely anything? If you could join REST APIs and databases with filesystems and dockerfiles? It’s possible in theory because those are all just datasources. Predrag Gruevski is trying to make it easy by building a universal query engine, with pluggable datasources,…

Software Systems Aren't Just Software (with Diana Montalion) 1:50:14

8M ago1:50:14

1:50:14

If you want to build really large software systems well, you have to stop thinking of them as just software systems. Beyond a certain size, everything your software touches becomes part of the wider system. You’re part of the system, your users are part of the system, and every other employee & department & priority eventually forms part of that sy…

Testing TVs At Scale With Elixir (with Dave Lucia) 1:16:05

9M ago1:16:05

1:16:05

Integration testing is always a tricky thing, fraught with problems setting up the right environment and attempting to control the system’s state. That’s particularly true when you’re dealing with a mix of software and hardware, and even worse when you don’t have control of what the hardware can do. This week I’m joined by Dave Lucia of TVLab’s, wh…

MicroServices For Better And Worse (with Ian Cooper and James Lewis) 47:09

10M ago47:09

47:09

What have we learned from more than a decade of deploying microservices? Was it a good idea? Are we any better at figuring out what a microservice is, or where its boundaries lie? Does splitting things up create fragmentation problems? And is it too late to put the genie back in the bottle? This week we’re going to look at all these questions and m…

Pony: High-Performance, Memory-Safe Actors (with Sean Allen) 1:13:23

11M ago1:13:23

1:13:23

Pony is a language born out of what should be a simple need - actor-style programming with C performance. On the face of it, that shouldn’t be too hard to do. Writing an actor framework isn’t trivial, but it’s well-trodden ground. The hard part is balancing performance and memory management. When your actors start passing hundreds of thousands of c…

Mapping is a hugely complex task to take on. Even if you moved as much of the data-management as you can out to 3rd-party services, you’d still have a tonne of work to do weaving together map tiles, routing information, GPS data, points of interest, search and more. And as if that wasn’t enough, you’d probably want that software to work on a whole …
