The more I learn about CAN bus the more I want to try it out. Not so much to connect to a car but to connect serval micro-controllers together. I'm thinking about splitting my aquarium controller project up into parts that would communicate over the wire.

Not every day a Hackaday article reaches into my life. We were unable to pay with visa card at a few different shops last month because of this. 💳

Still enjoying umami for tracking on my personal site and oblastle game.

Updating is as easy as going my VPS, pulling the new image, one line change in docker-compose.yml, and docker-compose up -d.

Got tricky this morning with serverless.yml

```diff
diff --git a/serverless.yml b/serverless.yml
index 82fa9e5..ebe568d 100644
--- a/serverless.yml
+++ b/serverless.yml
@@ -29,6 +29,8 @@ provider:

Resource:

```

In order to give my lambda fn permissions to query an index on the dynamo I had to use a cloud formation 'sub' method.

Stumbled across this cool Kubernetes tool. It does more but the development env feature most excites me. Imagine working on a frontend and API code bases locally and having clustered containers automatically get the changes and hot-reload. 🤯. So much less memory and CPU recourses needed locally.

Adding a keep_warm seems to have solved it!

Made this new AWS Lambda + DynamoDB solution over top of my Pleroma instance in order to speed up the micro-blog page of my personal site. Surly a quick DynamoDB query will be faster then VPS + Docker + Big Elixir App + Postgres query? Somehow not!?!

10515.3ms response time then the following are quicker. Next step looking into how lambda warmup works, and if the lambda has enough RAM allocated.
