It Works. That's the Problem. | Massdriver AI coding tools work shockingly well. That's what makes the structural risks so hard to dismiss. A reflection on productivity, dependency, and the quiet consolidation of the intelligence layer.

I'm conflicted w/ the efficiency AI has provided me.

It’s interesting because Dell and IPAs both suck ass.

I honestly like the simplicity of HCL. When a module gets painful, I know I'm doing something weird. It's all fancy JSON at the end of the day. Many teams look at modules like they are some amazing artifact to be preserved, I see them more as light abstractions hiding the operational bits from devs.

Guest Host: Kelsey Hightower — Why IaC Alone Isn’t Enough YouTube video by Massdriver

New podcast episode just dropped and this week @kelseyhightower.com flipped the mic and interviewed me!

We went deep on config management, ClickOps, and why the real problem in IaC isn’t Terraform — it’s knowing the right values for prod.

15 Years of Duct Tape: Why IaC Adoption Stalled at 30% Struggling to scale Infrastructure as Code? This post explains why CI/CD pipelines and Git workflows break down for modern cloud infrastructure, how brittle IaC practices slow teams, and why a new fou...

Infrastructure-as-Code adoption has stalled. Fifteen years in, only ~13-30% of companies have truly succeeded with IaC.

What’s blocking the rest of organizations?

Is Terraform too hard? It’s not the tool, it’s the workflow. www.massdriver.cloud/blogs/15-yea...

Didn’t notice carbon shit the bed on those images.

2. It's also a tracks preloads ...

We have an opts field on all get/list domain functions that let you request add'l info similar to JSONAPI, but at the elixir func level.

1. Inside the deploy/1 function, if the relations aren't loaded, it will load them and emit a telemetry event so you can find call sites missing data.

Considering open sourcing an #elixirlang macro at @massdriver.cloud that lets you declare what Ecto relations a function needs — like a typespec but for associations.

Absolutely obliterates N+1s

Thinking about open sourcing — would anyone actually use it?

This does two things...

This place is dead ᵃᶠ.

We collapsed about 6-7 services back into our monolith, cut out about 26 AWS services, refactored our storage engine on OCI, and of course we name our first test "poop" because we don't expect it to work and ... it did!

TFW it works.

Last night was the end of a two-month hack-a-thon for me and my cofounder. We've been asked time and time again to support running massdriver in self-hosted environments on-prem and in the cloud.

We didn't build massdriver for this originally.

"Ah, I understand now" is going to be my "What’s the Frequency, Kenneth?"

Ohhhh baby. Got some work to do on the docs, but the darn thing works.

I’ve had pretty good success so far writing my tests and then using my tests as my prompts, but this was my first time just straight up vibe coding / talking to cursor - literally not touching the keyboard at all, and wow, holy fuck it’s a mess

Yes lol

Yep a WIP. Trying my hand at vibe coding but the code is a bloodbath so I’ll probably actually write code like a 2024 troglodyte.

Parked a new hex package. Is the logo just right or what?

Working on this between self-hosted refactors: a tool that runs plan across all infra instances and flags changes from new policies. Like terraform plan but org-wide — real workloads, real environments. Context-aware, no more blind merges or finger-crossing.

We're getting ready to offer a self-hosted version of Massdriver.

I'm putting together a hardening guide for Elixir releases (Kubernetes/Docker, node comms, remote shell lock down, etc).

Anyone interested in collaborating or know of an existing guide I could contribute to?
