Bo... 15 Oct 2026 ### [A Bug Tracker You Have to Build Yourself](https://kaleb.au/blog/a-bug-tracker-you-have-to-build-yourself) I've published a lot of code over the years, and I have never once learned much from cloning it. That's the honest reason behind [zarlo/bug-tracker-plan](https://git.punksky.com/zarlo/bug-tracker-plan/): I wanted to teach web application fundamentals, and shipping a finished bug tracker would have been the worst possible way to do it. So the rep... 13 Oct 2026 ### [The Under-16 Ban Didn't Ban Anything. It Just Made Everyone Prove They're Not a Child](https://kaleb.au/blog/the-under-16-ban-and-what-it-actually-requires) Australia's under-16 social media ban came into effect on 10 December 2025. Ten months later I think it failed on its own terms, and that the privacy cost of trying has been considerably higher than advertised. ## First, the numbers [eSafety's headline figure](https://www.esafety.gov.au/newsroom/media-releases/platforms-restrict-access-to-47-million-under-16-accounts-across-australia) is that platforms restricted access to... 7 Oct 2026 ### [Building Things, Understanding Systems, and Staying in Control](https://kaleb.au/blog/build-things-understanding-systems) I've spent a lot of time building software, experimenting with infrastructure, and working on projects that sit somewhere between application development and systems engineering. Looking across the things I've worked on, there's a fairly consistent theme: I like understanding how things work, findin... 7 Oct 2026 ### [The Guest Never Gets a Port](https://kaleb.au/blog/the-guest-never-gets-a-port) The hard part of building an edge gateway to run other people's code isn't the sandboxing. Wasmer will give you a WASI sandbox in about four lines, and you can hand it a directory and go to lunch. The hard part is that once you're actually hosting untrusted workloads, you owe someone an invoice, a... 28 Sep 2026 ### [PowerDNS-Admin and the Record Nobody Can Edit](https://kaleb.au/blog/powerdns-admin-and-the-record-nobody-can-edit) PowerDNS-Admin is a good piece of work. It does forward and reverse zone management, user management with role-based access, SAML, LDAP and OAuth, two-factor auth, an API, and full IDN support, and it does all of it without ever asking you what you actually intend to use it for. I run hosted DNS o... 13 Sep 2026 ### [The High Court Is Deciding Whether Australia Needs a Power It Already Rejected at a Referendum](https://kaleb.au/blog/white-australia-and-the-1951-question) I want to be clear about where I'm standing before I make any argument, because it would be easy to read what follows as though I'm defending what this organisation says. I'm not. I don't like what they're saying. I'm not going to pretend my disagreement with it is a technical one that's rather t... 15 Aug 2026 ### [My Utility Belt: One Library in Go, One in .NET](https://kaleb.au/blog/utilitybelt-go-and-dotnet) Every product I build needs the same layer underneath it: a cache abstraction, some DTO shapes, base models with soft delete, an HTTP layer that emits OpenAPI, auth plumbing, and a handful of small things I always end up rewriting badly. That's [punksky/utilitybelt](https://git.punksky.com/punksky/utilitybelt/) in Go and [punksky/utilitybelt-](https://git.punksky.com/punksky/utilitybelt-net/)... 15 Jul 2026 ### [Three Forges, One Man](https://kaleb.au/blog/three-forges-one-man) There are three places my code lives: [github.com/zarlo](https://github.com/zarlo), [gitlab.com/zarlo](https://gitlab.com/zarlo), and [git.punksky.com](https://git.punksky.com/zarlo/) running on hardware I control. Two of them are dead weight and one is doing all the work, which took me a while to accept. ## GitHub has 95 repositories and none of them are new The numbers first,... --- ## Navigation - Previous: [Home](https://kaleb.au/index.md) - Next: [Freelance](https://kaleb.au/freelance.md) - Children: - [A Bug Tracker You Have to Build Yourself](https://kaleb.au/blog/a-bug-tracker-you-have-to-build-yourself.md) - [A FOSS Manifesto](https://kaleb.au/blog/a-foss-manifesto.md) - [A Quiet Admiration for the French Spirit](https://kaleb.au/blog/a-quiet-admiration-for-the-french-spirit.md) - [Building Things, Understanding Systems, and Staying in Control](https://kaleb.au/blog/build-things-understanding-systems.md) - [Building Bare-Metal .NET: Exploring NativeAOT Patching](https://kaleb.au/blog/building-bare-metal-net-exploring-nativeaot-patching.md) - [Bunny CDN Review](https://kaleb.au/blog/bunny-cdn-review.md) - [Replacing `Queue` With a `RingBuffer`, and Bumping Cosmos to .NET 10](https://kaleb.au/blog/cosmos-ringbuffer-and-dotnet-10.md) - [PowerDNS-Admin and the Record Nobody Can Edit](https://kaleb.au/blog/powerdns-admin-and-the-record-nobody-can-edit.md) - [The Guest Never Gets a Port](https://kaleb.au/blog/the-guest-never-gets-a-port.md) - [The Under-16 Ban Didn't Ban Anything.
