Human labour is largely invisible to AI
Lennard Berger argues that AI models look strong on evals yet lag in economic impact because much real work depends on invisible human labour—context, coordination, and judgment that benchmarks miss.

Is Structured Human Input the Missing Link in Agentic Work?
Long-running agents pause unpredictably for human input. Ben Greenberg argues A2A’s input-required state needs a schema contract—not free-form text—so pauses become reliable handoffs.

Blinking a Blue Pill LED with Rust, from scratch
A from-scratch Blue Pill walkthrough in Rust without a HAL: wiring and flashing, the reset vector, volatile GPIO writes, delay loops, and the assumptions a working blink can hide.

How Forge Structures Requests for Prompt Cache Reuse
Mohit Ranka explains how Forge, an open-source terminal-first AI IDE, restructures its agent harness requests—stable prefixes, message ordering, history persistence and cache hints—to maximise provider prompt-cache reuse, and how request snapshots plus usage tracking make cache behaviour observable.

SWE-sweep: Can Agents Autonomously Find and Fix Bugs?
Meta Superintelligence Labs and academic collaborators introduce SWE-sweep: agents must discover and repair latent bugs across 100 real repositories (~4.1k bugs) with no issue hints—early leaders resolve under 5%, highlighting bug finding as the hard part.

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.

Topcoat is pushing the boundary of server applications with Rust
Two monthshttps://tokio.rs/blog/2026-07-22-announcing-topcoat ago, we Julienhttps://github.com/pikaju and Ihttps://github.com/carllerche announced Topcoathttps://github.com/tokio-rs/topcoat, a batteries-included full-stack Rust framework. It includes views, components, mailers, an ORM Toastyhttps://github.com/tokio-rs/toasty, and more. Topcoat aims to make building web apps with Rust as productive as any other language. We have been hard at work shipping features, so it is a good time to talk about what is new.

Your Type Guard Can Silently Drift from Your TypeScript Type
