Damn, supply chain vector attacks are wild. Random guy in Primes stream was getting $40k offers to buy their open source project while in university and they have never made anything from it. What a social engineering attack this is. It would be so easy to make it look like a good deal and that the package was going to a good new owner who has real resources to maintain it.

Absolutely sick post. This is top tier animated blog posts. This posts demos how different queuing systems work with fantastic interactive demos.

2024 has been a wild year for infra with going “back” to on prem being made popular by @dhh. Well it looks like ahrefs saw right through the cloud trends an decided to ride the anti cloud train until it came back around to the station.

Being just a bit critical of the article it is impossible to get an apples to apples without actually running something of this scale and spending too much to find out. I cant imagine raw ec2 and ebs being the cheapest route into aws. They used no serverless tech in their article, but I digress, because I like this own your shit and build good product train.

What about People?!

This follow up does dive into the typical gut reaction that people cost a lot of money, you must account for them. You see when you hire people who are actually good at what they do, and run lean a lot of cost goes away, you have levels of management that disappear, levels of tooling that don’t need to exist, departments of IT don’t need to exist.

I am converting my docker compose env secrets over to k8s secrets. This guide was clear and to the point how I can replicate this exact workflow.

First set the secret, the easiest way is to use kubectl wtih –from-literal because it automatically base64 encodes for you.

kubectl create secret generic minio-access-key --from-literal=ACCESS_KEY=7FkTV**** -n shot

If you don’t use the --from-literal you will have to base64 encode it.

echo "7FkTV****" | openssl base64

Once you have your secret deployed, you have to update the container spec in your deployment manifest to get the valueFrom secretKeyRef.

Wow, shocked at these results. All this time I’ve been told and believed that k8s is incredibly hard, and you need a $1M problem before you think about it because it will take a $1M team to maintain it. So far my experience has been good, and I definitely do not have a $1M problem in my homelab.

Deleting a fly postgres db cluster was not straightforward to me as the app name is not inferred from the toml like it is for the main app.
