Why Buran Had Four Computers, Not Three — and What a Lean Proof Adds
**Date:** September 24, 2026 · **Author:** Dmitrii Zatona - Buran’s flight computer was four identical Biser-4 machines running the same programs synchronously. A comparison scheme blocked a failed one, and the design had to survive any two failures (Section 1). - Four is what two failures cost if a failed channel is found by comparing outputs alone. It is not the 3f + 1 of Byzantine agreement, which is a different problem (Sections 2 and 3).

Introducing WalShadow: Sub-second Postgres replication to ClickHouse from physical WAL
Today, we’re announcing WalShadow, an open-source engine that replicates Postgres data to ClickHouse directly from physical WAL. In our benchmarks, transactions committed in Postgres became visible in ClickHouse in around 200 ms, while WalShadow sustained 289K rows/sec, effectively keeping pace with the source Postgres instance. Unlike traditional CDC based systems, WalShadow doesn’t use Postgres logical replication. It consumes the same physical WAL stream used by Postgres replicas, decodes…

Platform-independent SIMD in Go
Go 1.26 and 1.27 include experimental APIs for Single Instruction Multiple Data SIMD operations. SIMD is a native feature of many modern CPUs that allows software to perform uniform operations across vectors of data very quickly, such as adding 8 pairs of float64 values in a single instruction. It can significantly speed up many computationally-intensive tasks, ranging from cryptography to data processing to AI. In fact, Go’s Green Tea garbage collector/blog/greenteagc even makes use of SIMD to accelerate scanning memory for live objects.
