Until recently, rewriting an established open source project could take years. With LLMs, that's changed. We're rewriting CRIU in Zig, and expect it to be complete in months, not y…

Another https://dagger.io fan here. Have been using it since late 2021 to continuously deploy a Phoenix app to Fly.io: https://github.com/thechangelog/changelog.com/pull/395 . Ever…

I really like the work that you're doing Thomas, this is the right approach. FWIW, https://fly.io/blog/carving-the-scheduler-out-of-our-orchest... is one of my favourite posts on y…

changelog.com used to be WordPress, then became a Phoenix app because it needed features that were hacky to implement & then manage in WP. It's more of a podcasting platform these …

I've never heard of ObjectiveFS, thanks for the share! I am more inclined to try out Rook, OpenEBS or Longhorn as open source alternatives. I've just added YugabyteDB to my explore…

For what it's worth, Rook, OpenEBS or Longhorn are worth exploring.

My first Supermicro just turned 9 and it's still running strong, with a fresh install of Ubuntu 20.04 & k3s over the holidays. The second Supermicro turned 5, and has been running …

We are both! I would also add lazy to that paradox. My surname is a letter off, and that's at close as it gets : ) The devil is in the details, there is more to it than dynamic & s…

K8S is an API that the majority is agreeing on, which is rare. There is a lot of amazing tooling, a staggering amount of ongoing innovation, all built on solid concepts: declarativ…

The primary reason behind the move was not wanting to manage CI. Since there were no options for a managed Concourse in 2018, we migrated to Circle, one of the Changelog sponsors a…

Yes, it does make sense to move static files to object storage, especially the mp3s. There is some ffmpeg-related refactoring that we need to do before we can do this though, and i…

I use Digital Ocean, Scaleway, Linode, Google, Cloudflare & Amazon on a daily basis, and I have experienced networking issues on all providers this year. It's all public, some even…

That was my favourite part too! Yes, we could have mitigated that entirely with CDN stale caching, but it was good to see what happens today, and then iterate towards better Fastly…

Block storage is an area that we are working with Linode to improve. That's the random read/write performance, as measured by fio. We have mostly sequential reads & writes (mp3 fil…

For a stable RabbitMQ cluster, you want dedicated RabbitMQ hosts with sufficient CPU, disk & network throughput for your workload. Most RabbitMQ users don't know what their workloa…

Disclaimer: I work for Pivotal, on the RabbitMQ team. We push Concourse to its limits every day. We work closely with Jenkins, GoCD, Travis & Concourse. They all have their limitat…

I'm all Ansible & Docker on my personal projects / servers, what a blast! http://gerhard.lazu.co.uk/ansible-docker-the-path-to-continu... More focus on the "why", less on the "how"…

And one more thing: the point of a system management tool is to have no dependencies. If you need to install or use anything other than the provisioner to setup a vanilla distro, y…

After 4 years of heavy Cheffing, I completely agree with most opinions expressed here. I'm pretty sure Puppet is just about the same, I have 0 experience with it though, I won't cl…
