OpenCode 2.0 turns the open source coding agent into a platform
OpenCode 2.0 shipped this week, and it is not a version bump. The open source coding agent, which sits at 213,000 stars on GitHub, rebuilt its server API from scratch, made its background service a first-class citizen, and folded almost everything into a plugin system. The upgrade path includes real breaking changes. If you script […]
GridCraft is a clean-room Excel clone in pure Rust, and it is further along than you would expect
An Excel-style spreadsheet in pure Rust with no telemetry, no subscription, and a permissive license sounds like a weekend demo. GridCraft is not that. It implements 513 of Excel’s 523 worksheet functions, ships as a native app on macOS, Windows, Linux and BSD plus a WebAssembly build, and just released v0.6.1 with about 3.9k stars […]
Someone Ported the TypeScript Compiler to Rust Without Reading It
When Microsoft announced its native TypeScript compiler rewrite, the team explained why they picked Go over Rust: garbage collection made the port tractable, and a Rust rewrite would need years and risk producing an incompatible language. This week a developer called that answer with an experiment. ts-rust is an experimental Rust port of the TypeScript […]
The C Standard Is Quietly Deleting Its Undefined Behavior
Martin Uecker stood up at Kernel Recipes 2026 and defended C, then immediately admitted the language’s biggest liability. The liability is undefined behavior, and the committee that owns the standard is now actively deleting it. Jonathan Corbet’s writeup of the talk, Reducing undefined behavior in the C language, is worth your time if you maintain […]
Cloudflare’s Web Search API puts grounded search behind one endpoint
Cloudflare quietly shipped one of the more useful pieces of agent infrastructure this month. The new Cloudflare Web Search API went into open beta on October 2, and it does something simple: it gives an AI agent live web results in a predictable format, billed and logged through the same place the agent’s model calls […]
VB6 Studio Web: A Classic Visual Basic IDE Rebuilt for the Browser
Visual Basic 6 shipped in 1998, and Microsoft stopped supporting the IDE in April 2008. Eighteen years later, VB6 Studio Web puts a working recreation of that IDE in a browser tab, form designer and all. No install, no Windows VM, no license key. The project, from Wieslaw Soltes on GitHub, is built from plain […]
The 40ms Go GC Pause That Came From Swap
A Go service on a Hetzner box was showing stop-the-world GC pauses of about 51 microseconds at the median. Then, a few times per hour, one pause hit 40 milliseconds. Same code, same heap, nothing in the application changed. The culprit was not the Go runtime at all. It was the Linux kernel deciding that […]
Azure Canvases Bring Cloud Work into the GitHub Copilot App
Microsoft announced Azure canvases for GitHub Copilot on September 30, and the pitch is simple: instead of bouncing between the Azure portal, the CLI, and your editor, the Azure tools you need sit in a shared workspace next to your Copilot conversation. Three canvases ship first: one for building and debugging Azure Functions skills, one […]
Azure SQL Dev Hub opens one front door for building against Azure SQL
Building an app against Azure SQL has always involved a small scavenger hunt: which service tier fits your workload, which connection library your language wants, which quickstart actually applies. Microsoft’s new Azure SQL Dev Hub, announced in public preview, tries to collapse that hunt into a single starting point in the Azure portal. Per the […]
Z.ai open-sources its whole coding agent stack with ZCode
The harness, not just the model Z.ai, the company behind the GLM model family, open-sourced ZCode this week, and the interesting part is the scope. This is not a CLI script and a README. The repository contains the desktop client, the browser workspace, the backend services, the shared UI, and the agent runtime that powers […]
Playwright Workspaces goes GA in three more Azure regions
Microsoft has taken Playwright Workspaces to general availability in Australia East, Japan East, and Switzerland North, bringing the managed browser-testing service to seven regions in total. For teams in those three areas it removes the awkward compromise of running end-to-end browser suites against cloud browsers an ocean away. What the service actually does Playwright Workspaces […]
Cloudflare quick tunnels get an agent-era relaunch
Cloudflare Quick Tunnels are back in the news this week, and the Hacker News thread about them hit 600-plus points in a day. The twist is that the feature itself is not new. Cloudflare launched quick tunnels in September 2021, and the company’s own announcement from that era describes the same core trick. What is […]
