Communication to future developers (including yourself) about how your code works, communication to the product team and stakeholders about what the product does, and even communication about domains and architecture. In this talk, we will discuss: - what bad tests look like and why they are bad - the audiences for tests - tips for how to present your tests to be understandable - using the Given/When/Then style - developing a domain specific test language - the benefits of BDD - using AI to help with all the above PUBLIC CONFIRMED Talk https://talks.kiwipycon.nz/kiwi-pycon-xiv-2025/talk/QMZCQN/ Plenary Space Richard Forshaw PUBLISH R9BK8Y@@talks.kiwipycon.nz -R9BK8Y Mapping the Open Source Ecosystem for Climate Science and Sustainable Technology en en 20251122T141500 20251122T144500 003000 Mapping the Open Source Ecosystem for Climate Science and Sustainable Technology This talk will be the second time I have given this talk, as earlier in the week I will be presenting a paper on the larger work at the OpenForum Academy Symposium in Rio, https://symposium.openforumeurope.org/.

COBOL and BASIC claimed managers would write their own programs. HyperTalk let anyone click-build a HyperCard stack. BPML and UML tried to generate systems straight from diagrams created by managers and experts in meetings. Constraint based rule engines argued that if you just captured every rule, which managers could just write down, then the code would materialise. Low-code platforms repackaged the dream for the web, and now LLM agentic assistants and “natural-language” IDEs are the latest contenders. So why do we keep hearing the same pitch? Because messy requirements, tacit knowledge, and perpetual change leak through every abstraction. Instead of vanishing, the complexity just moves... While developers, adapt, debug, and keep the lights on. History shows each wave actually _creates_ new niches for people who can straddle business intent and technical reality. In this talk I’ll: • Zip through six decades of attempts to eliminate developers, their bright ideas, brief wins, and spectacular failures. • Unpack the recurring traps: expressive ceilings, accidental complexity, maintenance drag, governance headaches. • Show how every cycle boosted demand for devs by making it easier to do business rather than development. • Hand you dead simple heuristics for sniff testing the big promises, spotting where these tools can help instead of hinder, and how to team up with AI tools without handing over your craft. Expect a breezy ride full of war stories, face-palm moments, and a few “hey, that actually worked” surprises.

In this talk we'll see an overview of the CPython interpreter and go through how you could implement a language that runs on it yourself. The end goal of the presentation will be to show how to write a compiler that can compile a small program that takes user input and calculates Fibonacci numbers. Along the way we should understand more about the interpreter's design, and how the design of the language as a whole lead to the interpreter we have today PUBLIC CONFIRMED Talk https://talks.kiwipycon.nz/kiwi-pycon-xiv-2025/talk/QUDN8S/ Breakout Room Oscar Horne PUBLISH YUUZ8A@@talks.kiwipycon.nz -YUUZ8A DNS as Code: A Review Of What's Out There en en 20251122T110500 20251122T113500 003000 DNS as Code: A Review Of What's Out There I'll share my journey exploring DNS as Code using Python, from the early days of editing named.conf and zone files directly on nameservers—with fond memories of working with BIND and PowerDNS—to evaluating libraries and tools like OctoDNS, StackExchange's DNSControl, and Terraform. Along the way, I’ll explain why I ultimately prefer using Python to interact directly with providers such as Metaname and Namecheap. You’ll see a practical DNS-as-Code workflow in action: managing zone files in Git, automating updates via provider APIs, and maintaining clarity and control without unnecessary complexity. Whether you're managing a handful of personal domains or supporting production infrastructure, this session offers tools, patterns, and perspective to bring DNS firmly under code-based management.

This talk will introduce the multiple different ways of spawning sub-processes in Python with simple & easy to understand examples. We will then have a brief look at the different implementations and their various use-cases. Then we will show how spawning processes in Python has always been fraught with problems for over 15 years. We will show real-world examples of seemingly unexplainable dead-locks and hard crashes when spawning processes in Python, especially in the context of multi-threaded applications. Lastly, we explain the reasons for those hard-to-debug dead-locks & hard crashes, show the problems that are associated to this day with using os.fork() & os.register_at_fork(). Then we will offer up how alternatives like os.posix_spawn() + vfork can help to make your Python programs more robust.

As the different datasets have no relation to each other, the data can be grouped in different ways, such as per variable, per datapoint, per date, etc. Each system that uses these files has its own preference as to how they are grouped and sorted, and to get all data from one grouping to another, the files need to be read, manipulated and written.

Or, specifically, we’re going to learn how large international jets taxi and take off from a runway. While thousands of planes take off and land safely every day, occasionally there are some close calls when disaster is averted by sheer luck or coincidence. In those circumstances, we get a safety investigation to help us learn from the mistakes and avoid catastrophic outcomes. This talk learns from one such safety report and we’ll discuss the parallels software engineers can learn from the aviation industry when communicating in complex operating environments.
