I've done a bit of a deep dive into how we produce our env. The flow is slightly complicated as some environment comes from the shell that the agent runs in and some comes from buildkite.com and then some is generated each job.

For context, the code that generates the job environment is here: https://github.com/buildkite/agent/blob/2f3d6935996d45877071c01f7b19ae07db302d69/agent/job_runner.go#L307-L426

Paraphrased, the process is:

• A build is triggered on buildkite.com, with user-provided environment (step or pipeline level) and bk specific env
• Write out base job environment to an env file for future reference and set BUILDKITE_ENV_FILE
• The agent job runner merges in it's env (overwriting anything set above, creating "protected" env)

This document outlines the steps to set up a one tunnel IPSec Site to site VPN on AWS and a VM on another cloud provider (Packet) running Strongswan.

(References:

https://openvpn.net/vpn-server-resources/extending-vpn-connectivity-to-amazon-aws-vpc-using-aws-vpc-vpn-gateway-service/)

Spin up packet VM and install strongswan

(This can be any cloud provider. It does not have to be Packet)

About the pic

Choria supports Federating multiple collectives of nodes into a large Federated collective for the purpose of orchestrating.

Federation Requests have:

• A orchestration request as normal
• Special headers listing which nodes its for

The client chops a large request into bundles of 200 nodes and publish them to the network for federation. Multiple federation brokers can thus take care of distributing it.

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).

1. pg_dump is a nifty utility designed to output a series of SQL statements that describes the schema and data of your database. You can control what goes into your backup by using additional flags.
   Backup: pg_dump -h localhost -p 5432 -U postgres -d mydb > backup.sql

   Restore: psql -h localhost -p 5432 -U postgres -d mydb < backup.sql

   -h is for host.
   -p is for port.
   -U is for username.
   -d is for database.
