In my case I wanted to avoid importing unused modules into a built JS bundle for a lambda environment using a shared codebase. Using a nested eslint file I could prevent this kind of import: import {ModelA, ModelB} from 'src/models' and instead encourage this kind of import: import {ModelA} from 'src/models/model-a'

{
  "rules": {
    "no-restricted-imports": [
      "error",
      {
        // prevent barrel file imports to have more control over what ends up in the js bundle
 "patterns": ["src/models", "!src/models/"]

Written in typescript and can be run with ts-node. You'll also need colordiff (brew install colordiff). Assumes much about the cdk.out file structure and CLI output format which may certainly change. This should give you two prompts: one for your environment (and the stack to run the diff for), and one showing you a list of lambda functions where assets have changed for which you can run a colordiff.

Replace the inline stack names, in this case mine are BackgroundJobsStackStaging and one for prod.

Useful for understanding the impact of deploying bundled code when it's changed. In my case, my lambda code bundles share common code with my API so it can change quite often with no impact on the lambda itself necessarily.

My Goal

I have a NetCDF I downloaded from firesmoke.ca (Bluesky Canadian Wildfire Smoke Forecasting System) and I wanted to retrieve the PM 2.5 value fo a given geo coordinate or nearest lat / lon.

Exploration Notes

The NetCDF file can't be opened as a textfile as it's a binary format but there's a few tools I used to inspect the data model inside:

Crafting a Reusable Github Action

The documentation for this common use case is sorely lacking...

Why this was needed:

I had a bunch of CI jobs (lint, test, type checking) that I wanted to run as separate jobs but share the same common steps for running checkout & dependency install

File structure

A third party Gradle plugin can be difficult to debug. In my case, I couldn't figure out why an input in my build.gradle file wasn't causing the plugin to add a desired task to a build. It's also not straightforward to inspect the source code of a plugin that arrives prebuilt. Fortunately if the plugin is open source, you can breakpoint in the source.

This thread forms the basis of these steps:

clone the source code for the plugin, and checkout the commit or version tag reflecting the version of the plugin you want to debug
open the repo in IntelliJ IDEA / Android Studio and allow gradle to sync
create a run configuration, selecting Attach to Remote JVM
make your breakpoints in the source code
in the project with the gradle build you want to debug, run ./gradlew --no-daemon -Dorg.gradle.debug=true app:uploadBugsnagReleaseSourceMaps, gradle will wait for a debugger to attach
back in the source code repo for the plug

lsof -nP | grep '(deleted)'

Useful for comparing the fingerprint shown by github at https://github.com/settings/keys against the public key on your machine to see whether it's a match:

ssh-keygen -l -E md5 -f ~/.ssh/id_rsa.pub

This lists the MD5 fingerprint
