Let the callers of your API control allocations
This is a post about performance. Most of the time when worrying about the performance of a piece of code the overwhelming advice should be (with apologies to Brendan Gregg) don’t worry about it, yet.

Redundancy vs. dependencies: which is worse? (2008)
I think that all other considerations are of the extrinsic real-world kind – domain modeling, usability, schedules, platforms, etc. I also think that I can show how any "good" programming practice is mainly aimed at minimizing redundancy, dependencies, or both.

A few CPU hardware bugs
Catherine (Whitequark)’s recent observations on poorly-engineered firmware reminded me of a few mistakes I’ve seen in vendors’ CPUs; some unimportant and others surprisingly bad. Since I’ve never seen these widely discussed, here’s some discussion and links to supporting evidence to make them more widely known, since…

Building a Distributed Log from Scratch: Scaling Message Delivery
In part two of this series we discussed data replication within the context of a distributed log and how it relates to high availability. Next, we’ll look at what it takes to scale the log such that it can handle non-trivial workloads. Data Scalability A key part of scaling any kind of data-intensive system is the…

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…
