Git packfiles use delta compression, storing only the diff when a 10MB file changes by one line, while the objects table stores each version in full. A file modified 100 times takes about 1GB in Postgres versus maybe 50MB in a packfile. Postgres does TOAST and compress large values, but that’s compressing individual objects in isolation, not delta-compressing across versions the way packfiles do, so the storage overhead is real. A delta-compression layer that periodically repacks objects within Postgres, or offloads large blobs to S3 the way LFS does, is a natural next step. For most repositories it still won’t matter since the median repo is small and disk is cheap, and GitHub’s Spokes system made a similar trade-off years ago, storing three full uncompressed copies of every repository across data centres because redundancy and operational simplicity beat storage efficiency even at hundreds of exabytes.
Good Inside digital memberships cost between $23.25 and $28 a month and the platform passed 100,000 subscribers in the third quarter of last year. The company has raised one round of funding, $10.5 million from VC firms including Alexa von Tobel’s Inspired Capital, in 2023. It’s otherwise bootstrapped by Kennedy and her co-founder Erica Belsky, another psychologist Kennedy met while studying at Columbia who is married to Scott Belsky, an early investor in Uber and Pinterest and an unofficial advisor to the company. Kennedy says she has no immediate plans to raise more money, but is open to the possibility.
