Kubernetes: Make your services faster by removing CPU limits
At Buffer, we’ve been using Kubernetes since 2016. We’ve been managing our k8s (kubernetes) cluster with kops, it has about 60 nodes (on AWS), and runs about 1500 containers. Our transition to a micro-service architecture has been full of trial and errors. Even after a few years running k8s, we are still learning its…

The fastest de-referer service... with AWS Global Accelerator
Yes, hiding HTTP-referers on your outgoing links are still a thing. Even though standards evolved, they rely on your user having a current browser, which is really something outside of your control.

Moving Marginalia to a new server
So the search engine is moving to a new server soon, thanks to the generous grant mentioned recently. If you visit search.marginalia.nu now, it may or may not use the old or new server. It’ll be like this for a while, since I need them both for testing and maintenance type work. I’ll also apologize if this post is a…

UPDATE 2025-05-19 Somewhat un-suprisingly AWS has closed the loophole that I was exploiting for this https://aws.amazon.com/service-terms/#30._AWS_Lambda and as such compiling data into your lambda …

Clog: Making a homegrown ClickHouse log for $20 a month
There was recently a discussion on Hacker News around application logging on a budget. At work I've been trying to keep things lean, not to the point of absurdity, but also not using a $100 or $1000/month setup, when a $10 one will suffice for now . We settled on a homegrown Clickhouse + PHP solution that has…

Switching to Fedora Silverblue
For the last 10 years or so, Arch Linux has been my Linux distribution of choice. The early years were a bit rough, and the process of moving to systemd wasn't without its challenges either, though the experience has improved dramatically since then. In spite of these improvements, certain issues persisted, such as…

Setting up a Raspberry Pi with 2 Network Interfaces as a simple router
I needed a very basic 'Internet sharing' router setup with one of my Raspberry Pis, and I thought I'd document the setup process here in case I need to do it again. I should note that for more complex use cases, or where you really need to worry about security and performance, you should use something like OpenWRT…

The utilization of 44/8: the reason I mapped IPv4 and IPv6
In the early days, when the Internet was just beginning, back in 1981, radio amateurs were allocated, by what is now known as IANA , an IPv4 block for usage and experimentation by all members of this hobby, internationally. This block was 44.0.0.0/8, which is a huge amount of address space by today’s standards, but…
