Numerics.NET with Jeffrey Sax

So what can numerics do for you? Carl and Richard talk to Jeffrey Sax about his work building Numerics.NET, a collection of general-purpose mathematical and statistical classes built for .NET. Jeffrey explains that numbers in a computer differ from real numbers in the world; for storage and computational efficiency, typical variable types in any programming language have limits on precision and size. How those variables are used can affect the outcome, with potentially disastrous consequences. Numerics.net provides exacting control of precision, as well as complex mathematical functions.…

Constraining Agents for Software Development with Don Demcsak

How can constraints make software development assistants more efficient? Carl and Richard talk to Don Demcsak about his work on getting LLMs to build higher-quality software with fewer resources. Don talks about how domain-driven language techniques help to define and constrain language around a given application problem space, but that largely hasn't been applied to coding agents so far. And as powerful as domain-driven is, it has challenges when it comes to building applications - and, more importantly, testing them. That's where behavior-driven approaches have advantages, which can also…

Arguing about AI with Billy Hollis

Ready for a rant? Carl and Richard talk to Billy Hollis about the impact of artificial intelligence on software development. The conversation starts with a listener comment about going all-in on AI to speed up development radically, which raises the question of how much AI is the right amount. What's safe and what is reckless? And how will that position change over time? Are the problems we're having today just growing pains of the tools, or are they systemic to the technology? Lots to debate!

Identity is Hard with Michele Bustamante

Identity is hard, and getting harder! Carl and Richard talk to Michele Bustamante about the evolution of authentication and authorization in the current landscape. Michele talks about finding apps at clients that are still using older authentication strategies that are no longer secure - or are implemented incorrectly, so they were never secure! The conversation covers the array of tools available today for security, so you don't need to roll your own, and includes support so you can do it right. The role of the LLMs is important - old significant vulnerabilities are being found and fixed…

Use What Works with Dylan Beattie

Use What Works! Carl and Richard talk to Dylan Beattie about the Use What Works movement, encouraging developers to use well-maintained open-source projects available today rather than rolling their own. Dylan explains how folks go down a path of believing a library is simple until they learn enough to realize that every bit of software is more complicated than they realize. And the less code you own, the happier and more productive you are. Adding AI to the mix only makes it clearer: you need some stability in development. If you're changing every layer of code, you'll spend even more time…

How We Beat the Y2K Bug

The Y2K bug turned out to be a non-event on January 1, 2000. How did that happen? Carl and Richard bring together a number of stories from folks who were there, fixing the software and updating systems, so effectively that, ultimately, nothing much happened when the clocks rolled over. It was common practice with early software to only store two digits worth of year - back then, storage space was at a premium. For years, there had been warnings about fixing these problems, but by 1999, it was essential. These are the stories of how some folks did those fixes so effectively that when Jan 1…
