This guide shows how to self-host SMTP on a cheap VPS. It runs Dockerized Postfix and bundles opendkim for DKIM signing.
It skips IMAP and inbound SMTP and relies on registrar email forwarding. It configures reverse DNS plus SPF and DMARC DNS records.

| How we fixed Postgres connection pooling on serverless with PgDog |
| |
| |
A startup swapped Supavisor and PgBouncer for PgDog on EKS. The swap stopped serverless deploy connection spikes. A multi-threaded, colocated pooler handled the bursty traffic.
PgDog needed fixes for Prisma prepared-statement handling. The team shipped those. PgDog now exports metrics via OpenMetrics to Prometheus/Grafana. It supports health-aware load balancing. That combo let the startup shrink Supabase hosts and cut costs. |

| California’s AB 1043 Could Regulate Every Linux Command, and the Open Source World Is Too Quiet |
| |
| |
California's AB 1043 requires operating systems to collect age/DOB at account setup and expose an API that returns an age bracket signal. Apps must request that signal on launch and restrict access by bracket. Effective Jan 1, 2027, vague definitions could sweep apt, flatpak, snap, and package managers into enforcement. Violations carry fines up to $7,500.
System shift: The law moves age gates to an OS-level API. That forces decentralized package ecosystems to adopt identity signals or seek carve-outs. Expect friction. |
