Migrating the GitHub Copilot runtime to Rust, using Copilot
A rewrite this size wasn't affordable before agents. Here's what porting the Copilot agent runtime to 800,000 lines of production Rust actually took.

How Early Is Too Early to Warn About a Bubble? Looking at AI in 2026
Historical warnings arrived months or years before market peaks. This article compares those lead times with the AI investment boom and asks which signals matter more than the word bubble.

How we migrated lovable.dev away from Next.js and turned it into another Lovable app | Lovable
42M monthly visitors, 400 routes and 850K lines of code moved from Next.js on Vercel to TanStack Start on Lovable—route by route, mostly by agents, with one 11-minute incident along the way.

After studying how coding agents interact with our projects and how we can build an efficient harness to prevent errors from these actors, I realized that worktrees are an important strategy for isolating the work of different agents working simultaneously woliveiras.com/posts/why-gi...

Why Git Worktrees Matter More in the Age of Coding Agents
Git worktrees predate coding agents. Learn what they share, what they isolate, and why parallel agents make this old Git feature feel like infrastructure.

Great story from ABC this morning about a chap in Melbourne who asked an AI agent (OpenClaw) to book a gym class, and it ended up hacking the gym's booking system to kick people off the waiting list. www.abc.net.au/news/2026-08...

How a simple request for AI to book a gym class exposed a major threat
When Andrew asked his AI personal assistant to book him a spot in a gym class, he had no idea he would accidentally initiate an autonomous cyber attack.

I feel that now it is a bit different from the experiences I had in the past. Either companies take control of these kinds of tools (Gen AI for coding), or an entire sector can be blocked because of a vendor API issue

But most of the internal tools I've worked with were not so nice 😂😂😂

William Oliveira @1ilhas.bsky.social · 10/08/2026
I think it'll depend on the platform team and the company goals with these kinds of internal tools. I've worked on a company with really good internal tools, but they have a strongly focused team for doing it AND give them total freedom and money for that

How Companies Are Replacing AI Coding Subscriptions with Internal Developer Platforms
Companies are unbundling coding assistants into internal agents, gateways, private inference, tools, and governance. Real deployments show why control often moves in-house before frontier inference do...

William Oliveira @1ilhas.bsky.social · 09/08/2026
The evidence suggests that control-plane ownership usually comes before full inference replacement. In many cases, companies still rely heavily on external frontier models, while moving high-volume or sensitive workloads to specialized internal systems.

William Oliveira @1ilhas.bsky.social · 09/08/2026
- Internal coding agents and model-neutral clients - SSO, access control, centralized policy - AI gateways and model routing - Private or self-hosted inference - Repository, documentation, CI, and MCP integrations - Sandboxed execution and observability - Frontier-model fallbacks for difficult tasks

Companies such as Cloudflare, Samsung, Meta, Walmart, Zup Innovation (Brazilian like me ❤️), and others are taking different parts of the stack in-house:

William Oliveira @1ilhas.bsky.social · 09/08/2026
The most interesting shift is not from one model to another. It is from renting an inseparable coding product to operating a platform where agents, models, tools, and providers can be replaced independently.

William Oliveira @1ilhas.bsky.social · 09/08/2026
Acabei de publicar! Are companies really replacing GitHub Copilot, Cursor, Claude Code, or Codex with local AI models? The answer is more nuanced than “just run an open model on a GPU.”
