Introducing WalShadow: sub-second Postgres replication to ClickHouse from physical WAL.
No logical replication. WalShadow decodes the same physical WAL stream Postgres replicas use and writes ClickHouse-native blocks directly into ClickHouse. In our benchmarks: ~200 ms commit-to-visible latency and 289K rows/sec sustained, keeping pace with the source Postgres.

Red flag in your architecture:
Your "microservices" all share the same database.
What you actually have:
- A distributed monolith with network latency added for free
- Schema changes that require coordinating deployments across 8 services
- One slow query in Service A that kills performance for Services B through G
- Connection pool exhaustion that cascades across services you thought were independent
- All the complexity of microservices with none of the benefits
Sharing a database between microservices doesn't make them micro. It makes them a monolith that's harder to debug.

Been quietly building this one for a long time. A small glimpse into the chaos and clarity inside my head. Out August 15 on my own label Hyperreal.

We replaced our React frontend with Go + Webassembly. So we thought we would share an in-depth post about how it went, and whether you should do it too.
We're currently observing a massive surge in sign-ups for @ProtonVPN originating in the U.S.
Typically, we see such spikes from countries with unstable governments facing internet shutdowns, meaning this is an anomaly.
