Roles and Service Account

To grant a user or our new app to do something on any resources on Google Cloud Platform, we or our app need permission that will grant us to perform anything that we want to do.

Two examples are:

We as user want to create a new Compoute Engine instance from Google Console. Then, we or let's say in this case our email need to have set of permission that allow us to create new instance.
Our new app made in Python deployed to Cloud Function need to create a Cloud Task queue or HTTP Task. We know that this app is triggered by HTTP request. How does Google know who run the app (not the one send the request)?

Operating System

Although this apply and proven to openSuse 15, but it is possible to apply this to other operating system.

Issue

When updating kernel to newer version, sometimes the process is halt since we are running out of /boot space. Typical error message is shown below.

installing package kernel-default-5.14.21-150500.55.19.1.x86_64 needs 2MB on the /boot filesystem

Can't use multiple equal or not equal

❌ We cannot use more than 1 NOT_EQUAL operator

allPost, err := fsClient.Collection("posts").
    Where("name", "!=", "post").
    Where("name", "!=", "quote").
    Documents(ctx).
    GetAll()

Convert SVG to PNG

Install ImageMagick first.

convert -density 1200 -resize 200x200 -transparent white input.svg output.png

Checking Order when run/test a file.go

When we invoke go run file.go or go test, the compiler will check the following file sequentially. This is my observation and I don't have any valid resource to validate it.

file *.go (file.go)
- check import-ed module
go.mod
- check file exist
- if missing, error: go.mod file not found
check module name
