Arch Linux Now Has a Bit-for-Bit Reproducible Docker Image
As a follow-up to the similar milestone reached for our WSL image a few months ago, I’m happy to share that Arch Linux now has a bit-for-bit reproducible Docker image! This bit-for-bit reproducible image is distributed under a new “repro” tag. The reason for this is due to one noticeable caveat: to ensure…

Bucketsquatting is finally dead
For a decade, I have been working with AWS and third-party security teams to resolve bucketsquatting / bucketsniping issues in AWS S3. Finally, I am happy to say AWS now has a solution to the problem, and it changes the way you should name your buckets.

Amazon Web Services – Four Years and Out
Today marks four years since I joined AWS. My last day will be Friday.\nI have to say being fired from AWS is actually a relief. There have been a lot of changes to the company since I joined in 2022, and the company I wanted to work for is no longer the same company.\nThis past year, while I was doing my best to make…

Starlink Mini as a failover
I recently picked up a Starlink Mini to use as a backup connection for my home network. The underlying technology is fascinating - thousands of satellites in low Earth orbit delivering broadband almost anywhere. With the new £4.50 standby plan, it's an excellent way to keep things online.

I tested every IP KVM in my Homelab
Since the PiKVM came out in 2017, there's been an explosion of IP KVMs. I've tested almost every one. But what are they good for? You can use Remote Desktop, Screen Sharing, or VNC to remote control a computer from anywhere on a LAN. And if you don't have a private VPN, you could use RealVNC, Raspberry Pi Connect, or…

If you don't run your own LLM proxy, how do you know whats going on?
I think the title captures the idea fully but I'll dig into it because this ain't Twitter. You're working an idea, a piece of code, or a multibillion a year SaaS app which is probably saving the world. Maybe you're automating the cloning process of grabbing

Alternatives to MinIO for single-node local S3
In late 2025 the company behind MinIO decided to abandon it to pursue other commercial interests. As well as upsetting a bunch of folk, it also put the cat amongst the pigeons of many software demos that relied on MinIO to emulate S3 storage locally, not to mention build pipelines that used it for validating S3…

Zeroserve: A zero-config web server you can script with eBPF
zeroserve is a small, fast, zero-config HTTPS server. You hand it a tarball of a website and it serves it - over HTTP/2 and TLS 1.3, with hot reload and a tiny resident footprint. The twist is that you can drop eBPF programs into the tarball and they run on every request, in userspace, as sandboxed middleware …

My Home Fibre Network Disintegrated
Thanks HN folks for all the comments. To clarify a bit, the cables are pulled through PVC conduits under the flooring before being buried in cement. Currently the hypothesis for why the cable disintegrated so quickly is hydrolysis. Singapore is extremely humid after all. A second possibility is that I keep the…

I just want simple S3
I just want S3. My needs are pretty basic. I don't need to scale out. I don't need replication. I just need something that can do S3 and is reliable and not slow. Minio is dead, they pulled the plug after axing the interface. They archived the repo so they …
