You should have lots of AWS accounts (via) Richard Crowley makes the case for maintaining multiple AWS accounts within a single company, because “AWS accounts are the most complete form of isolation on offer”. # 6:36 pm
Querying Postgres Tables Directly From DuckDB (via) I learned a lot of interesting PostgreSQL tricks from this write-up of the new DuckDB feature that allows it to run queries against PostgreSQL servers directly. It works using COPY (SELECT ...) TO STDOUT (FORMAT binary) which writes rows to the protocol stream in efficient binary format, but splits the table being read into parallel fetches against page ranges and uses SET TRANSACTION SNAPSHOT ... in those parallel queries to ensure they see the same transactional snapshot of the database. # 2:27 pm
Figure out how to serve an AWS Lambda function with a Function URL from a custom subdomain (via) This took me five hours and 77 issue comments to figure out, but I finally managed to serve an AWS Lambda function running Datasette on a custom subdomain with an HTTPS certificate. I was going to write this up as a TIL but I’m exhausted so I decided to share my private notes thread instead. # 12:29 am
