VADOSWARE

Sometimes, if Prometheus gets too chatty with your mail server (it should never be looking for metrics on port 25 anyway), it can overwhelm SMTP servers which perform backoff for bad requests.

Looking to run Postgres on ZFS? I've gathered some of the information and sage advice out there to give you a head start on figuring out how to do it safely and efficiently.

A while back, I had a somewhat soft node failure due to Calico not allowing the same node to come up under a different IP address.

Wondering what happens when a hard drive you're using on a Hetzner dedicated server fails? Wonder no longer.

I used Baserow (https://baserow.io) as the backend for a tiny landing page built for NimbusWS (https://nimbusws.com). Yak shaving aside, building with Baserow was quicker, easier, and much easier to manage/administer than other solutions I might have chosen in the past.

I recently reworked my storage setup in pursuit of both production and flexibility. Looking at the F/OSS space led me to OpenEBS ZFS LocalPV with Longhorn on top, and here's why.

A quick list of features which Haskell benefits from that your language probably doesn't

How to use variables from your inventory file, once and for all

A quick and simple guide to automating your k0s cluster backup with ansible and systemd. You can probably guess the code you're about to read.

If you're running on Hetzner, you might want to update your DNS settings to use some other resolvers. This can problem can manifest if you're trying to resolve DNS names that resolve to your own machines *from inside your own machines*.

Want to wait for some Kubernetes resources and don't want to write a full reconciliation loop/operator? Here's how to hack it.

A quick writeup on the 'deployment spectrum' and it's history, as I see it.

I stood on the shoulders of the giants over at wickedtemplates (https://www.wickedtemplates.com) who open sourced wickedblocks (https://blocks.wickedtemplates.com/) and built their tailwind templates into individual components powered by lit-html, which is now called Lit (https://lit.dev/)

Watch out for kernel version mismatches after system updates (i.e. updates of the 'linux' package) -- spooky behavior can occur if you're not careful

You may not need Flux/ArgoCD or any fancy automated reconciliation loop deployment process just yet! Plain old CI runners work quite well for simple automated deployments (this approach powers this blog right now!).

Some quick code (PG migrations) to enable converting an auto-generated postgres primary key index to a covering index

A few more Paxos papers to take a gander at -- Quorum reads, Compartmentalization, Matchmaking and Pigs. The Paxos family of consensus protocols (and their papers) are as colorful as they ever were.

Part 4 of a series on how I write REST-ish web services in Haskell with a dash of robustness

A step by step guide on how to set up SES with Pulumi

A small exploration and guide (with repo) into exposing SSH to a container in a Pod over port 443 (which is normally used for HTTPS).
