When Time Machine inevitably breaks, here's how to fix it.

Try doing First Aid using Disk Utility. Should repair any permissions that are messed up.
Will add 2 next time I run into it :-).

Cheat sheet for advanced Excel formulas

Concatenate strings this way:

=A1&” more text”

Restrict action to just changes to the "public" path:

on: 
  push:
 paths:

Goal here is to monitor disk space usage on my parents' iMac, push it to Kinesis, and alert if it hits a certain threshold.

Set up a Kinesis stream called osquery-firehose.

Run the osquery shell with osqueryi

Show hard disk space remaining:

select path, type, round((blocks_available * blocks_size *10e-10),2) as gigs_free from mounts where path='/';

Integration test:

@Test(groups = [INTEGRATION_GROUP])
fun `$END$`(){
}

Add Kotlin logging:

Start localstack with just S3 running on port 4572 in region us-west-2.

docker run -e "SERVICES=s3:4572" -e "DEFAULT_REGION=us-west-2" -p 4572:4572 localstack/localstack

Create an S3 bucket:

aws --endpoint-url=http://localhost:4572 s3 mb s3://test-bucket

A cheat sheet to assist in conversion of Java syntax to Kotlin.

Convert Java file to Kotlin, then replace the thenApply that gets generated with the correct Kotlin syntax.

Regex:

	// Toggles hidden state of self view when using SimplePractice telehealth

	function toggleSelfView(){
	var selfView = document.getElementById("publisher")
	if (selfView.style.display === "none") {
	selfView.style.display = "block";
	} else {
	selfView.style.display = "none";
	}
	}
