cert-manager Cloud native X.509 certificate management for Kubernetes and OpenShift

I've been trying to use GCP Managed Certificates with DNS Authorization, but no success.

I guess that I'll have to try cert-manager.io ... I was hoping for something easier and more straightforward.

Back to playing with k8s & Google Cloud:
1. Postgres StatefulSet ✅
2. Redis ✅
3. Google Secrets ✅
4. NextJS App (+load google secrets on boot) ✅

But now, I'm struggling hard to get a Wildcard Certificate working with my Ingress/LB 😭

Visual representation of services in a railway dashboard

Visual representation of services in a railway dashboard

With railway.app I have:
- 2 next.js apps
- 2 node.js apps
- 2 postgres
- 1 redis
- 1 temporal ui
- 1 temporal engine

And pay like $12 per month (monitoring stuff is currently paused as it would add an extra $8)!

Breakdown of amount paid for a single day in google cloud with an empty kubernetes cluster. - Kubernetes engine: €3.46 - Could Monitoring: €0.83 - Networking: €0.38 Total: €4.68

Playing around with @kubernetes.io on GoogleCloud - spun up an empty cluster, deployed a couple of Docker images… and got an instant €5 bill on day one.

Amazes me how services like railway.app and fly.io manage to offer so much at such low prices!

It’s 4 years old, but given the stability of go, most still applies. Only missing a chapter or two on generics (they weren’t released back then)

Matt Holiday‘s “go class” is a masterpiece. Can’t believe there’s content of this quality freely available. It’s been a good learning experience not only in @golang.org but also in software development as a whole.

I’ve been working on a side project—a blog-like platform focused on photography. It’s a space where photographers can blend storytelling with their visuals.

Not sure if it will ever see the light of day, but I’ve learned a lot along the way.

For now, the CLI is local, but it has already streamlined my workflow significantly. Managing tasks in Chronical feels much more organized and efficient now.

One thing I haven’t figured out yet is how to publish the CLI for global use. The ESM + TypeScript combo has made this trickier than expected, and I’m not willing to spend too much time on it for now.

I used `@effect/cli` to build this, and it took just a couple of hours to have everything done and ready to merge! Effect is as brilliant as ever. 🎉

Switching between folders to perform these tasks was manageable for now, but in a few months, I’d probably feel lost trying to find specific tasks.

To solve this, I built a centralized CLI to keep all these tasks in one place. It’s a huge help in reducing cognitive load.

In my monorepo, I had several tasks scattered across different packages.

* Run @temporal.io workflows manually
* Deploy smart contracts with hardhat (local/testnet)
* Create/deploy local graphs with @graphprotocol.bsky.social
* Run migrations/seeds ...and more.

GitHub - mattm/sql-style-guide: An opinionated guide for writing clean, maintainable SQL. An opinionated guide for writing clean, maintainable SQL. - mattm/sql-style-guide

This style guide puts into words some of the unspoken (and OCD-like) rules I follow—and adds a few I’ll adopt.

One concept I plan to explore further is CTEs. I’ve used them sporadically, but after reading a few articles, they seem worth a deeper dive.

Got Prometheus metrics set up and dashboards running in Grafana for some generic metrics. Still need to explore good insights and custom metrics, but it feels great to have the foundation in place!

Although Chronical isn’t live yet (zero users 😅), I’m using it to sharpen my engineering skills. This week, I focused on Grafana & Prometheus, and as soon as I set up tracing, I found a couple of performance improvements. Insights like this feel like a superpower! #buildinpublic

In Chronical, users can customize parts of the overall theme to better align with their brand. While customization options are currently limited, our goal is to give users the tools to make their publications truly reflect their brand identity.

I got interested when i saw Evan ‘s announcement of VoidZero, but it’s still early, the formatter is not available yet. I’ll keep an eye, for sure!

Apple pencil hover effect is sooooo good! I love it on the freeform app, but works so well on some websites as well, check how great it is at effect.website docs.

I usually track the text I’m reading with the pencil (and point at stuff), and here I get extra info in the hover dialogs 🥰

Probably these were the ones with the most impact:

Effect - effect.website (discovered in 2023, but gone more in-depth in 2024)
Temporal - temporal.io
Railway - railway.com
Cursor - cursor.com

I would include Biome, but I'm still struggling with having it working properly with my monorepo.

Finally, I implemented an optimistic pre-fetching strategy: while viewing an image, the assets to its left and right in the gallery are preloaded. This way, transitions feel instant when navigating between images.

Next, I tried blurring the currently displayed image and adding a loading spinner while fetching the next one. It looked better, but the transitions still felt slow and awkward—blurring an already fully loaded image didn’t feel right.

The first step was tweaking the `react-query` to keep the previously image data during transitions. This removed the blank screen issue, but the transitions still felt unresponsive.
