Oooooh boy. Let’s get this out of the way first. Email sucks. Now to the how and the why. We’re builders. We love making tools to help designers and developers live a little bit easier. We’re pretty good at it. Marketing, though? We do our best, but the truth is, we don’t like to bother […]
Starting from a wiped family photo drive, a walk through everything a real backup needs: snapshots, rotation, deduplication, offsite copies and tested restores.
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…

An inside look at how OpenAI scaled PostgreSQL to millions of queries per second using replicas, caching, rate limiting, and workload isolation.
NOTE June 2026: Hetzner announced over 100% increases in prices. They will honour old prices for instances built before June 15th 2026, but for new instances the performance/price ratios show below are no longer valid.
If you need a basic NAS and don't care about GUI features, it is suprisingly simple to set up a ZFS dataset and share it over the network using Samba.
In my previous blog posts, Azure’s Weakest Link? and Azure’s Weakest Link - Full Cross-Tenant Compromise, I gave an overview of the severely insecure architecture behind API Connections in Azure, a part of Azure Logic Apps, and an instance of a full cross-tenant compromise using these inherent flaws. Now I am back…
Custom PHP2Shell Exploit Chained with Kernel LPE to Root Versions of Palo Alto Networks PAN-OS Firewalls in the Wild
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.
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…
The technical musings of Iain Cambridge.
OpenAI and Google Cloud are bringing frontier models and Codex workflows to Gemini’s Model Garden, available through Google Cloud Marketplace.
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.
Every Browser Use Cloud session runs in its own Firecracker microVM on regular EC2. It starts in under a second and costs $0.02 per browser hour, down from $0.06.
Deploy globally, query over HTTP, and scale reads with low latency. Bunny Database lets you build fast without paying the serverless tax.
When you request a certificate from Let’s Encrypt, our servers validate that you control the hostnames in that certificate using ACME challenges. For subscribers who need wildcard certificates or who prefer not to expose infrastructure to the public Internet, the DNS-01 challenge type has long been the only choice…
We cut PR wait time and running costs by rethinking CI as a system, from the infrastructure underneath it to how work gets scheduled and tests get parallelized.
Rails 8 eliminates Redis from the default stack. Learn how SolidQueue, SolidCache, and SolidCable replace Redis for job processing, caching, and real-time updates—powered entirely by PostgreSQL. Explore the true cost of Redis, how SolidQueue works, when it scales, and how to migrate from Sidekiq to a simpler…
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…

We're building AI Gateway into a unified inference layer for AI, letting developers call models from 14+ providers. New features include Workers AI binding integration and an expanded catalog with multimodal models.
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
