It isn't unexpected that the focus of the Bun Rust rewrite is on the anti-Zig side more than anything, since the internet loves to hate. What is unexpected and unfortunate is that leadership within Bun hasn't tried to steer the conversation away from that at all.

There are so many positive and interesting takeaways from this and I'm not really seeing any of them pushed as the primary message.

A positive thing that hasn't been talked about at all is how far Bun came thanks to Zig. And even if you dump it now, its meaningful for how good Zig was to even build a product to this point and impact by any metric. I would've loved to see anyone in leadership say this.

On the interesting side is how fungible programming languages are nowadays. Programming languages used to be LOCK IN, and they're increasingly not so. You think the Bun rewrite in Rust is good for Rust? Bun has shown they can be in probably any language they want in roughly a week or two. Rust is expendable. Its useful until its not then it can be thrown out. That's interesting!

There's been a lot of talk about memory safety and no doubt Rust provides more guarantees than Zig. But I'd love to see a better analysis of why Bun in particular suffered so much rather than take the language-blame path. How could engineering as a practice been more rigorous to prevent this? What were the largest sources of crashes other programs should watch out for? How does Rust prevent them? How could Zig theoretically prevent them? That's interesting.

I know the official blog post hasn't come out yet from Bun. But they're smart enough to know that that PR would stir up controversy the moment it opened, or they should've been. And plenty in the company have been tweeting and writing about it. Its somewhat telling to me in various dimensions what they chose to talk about first.

I tend to think I'm pretty good at corporate PR/comms (especially when it comes to developer audiences) and I think appealing to the negative is never the right long term strategy; it does work to get short term eyes though.

VS Code was already used by millions of developers for agentic coding. However, the editor layout has traditionally been optimized for single-task and single-workspace workflows.

Today, we're introducing a new window to enable our users (and ourselves!) to work with multiple agents across multiple projects: Agents.

Now available in VS Code stable!

There are few things as lame as dunking on an engineer asking for feedback, esp in public.

Honestly, a dev that has asked for feedback *once* in their lives, *in public* is already top 1% or above. Doing it regularly is somewhere too 0.0X%

It adds up+makes big differences

What AI coding agents are missing isn't capability. It's discipline.

Superpowers ships TDD, debugging, planning, and verification as a folder of markdown files. Same folder runs on six AI agent runtimes.

It's coming

[GitHub @github]

Starting June 1st, GitHub Copilot will move to a usage-based billing model as GitHub Copilot supports more agentic and advanced workflows.

In early May, you'll see a preview bill experience, giving visibility into projected costs before the transition.

Steve Yegge's 8 levels of AI-assisted development have a very large missing rung between juggling 10 agents by hand and building your own orchestrator.

I wrote up the five rungs I think are there, from my own climb so far.

@FrancescoCiull4 Thanks!

[Marc Nuri @MarcNuri]

I've been promoted to Senior Principal Software Engineer at Red Hat.

Built the Kubernetes MCP Server, went all-in on AI-assisted dev, kept maintaining Fabric8 + JKube. The most intense period of my career, this milestone means everything.

@cedricclyburn Thank you!

Please do!

OK @eastdakota real talk: why doesn't Cloudflare buy La Liga. It's 8% of Cloudflare's market cap.

Then you can:

1. Stream La Liga, globally, as a massive subscription business, using your edge network, better than it's ever been streamed

2. Liberate Spain

Kidding not kidding

[Gergely Orosz @GergelyOrosz]

It's hard to believe that the "~80%+ of the internet is blocked in Spain during football games" claim is true - but it is!! And has been for years.

The government is sabotaging their complete digital economy... for La Liga, a private football org worth €5B. Pure madness

@myfear Thank you! 😊

@vilojona Moltes gràcies 😊. També per la part que et toca en aquest camí i la teva ajuda 😉

This is either brilliant or scary:

Anthropic accidentally leaked the TS source code of Claude Code (which is closed source). Repos sharing the source are taken down with DMCA.

BUT this repo rewrote the code using Python, and so it violates no copyright & cannot be taken down!

[Marc Nuri @MarcNuri]

@svpino @cubesol_greg Before it was unthinkable to rewrite from scratch. Now it might be easier than ever to rewrite entire crappy codebases with a proper design (whoever implemented those in the first place 🙍‍♂️🤖)

[Darren Shepherd @ibuildthecloud]

I've already gone through this thought exercise. Why does it matter? "It shouldn't matter because the AI manages it." This logic is completely flawed. You have to see it in practice. AI does not turn an engineer into a 10x engineer. I can supe up a Civic and it will do 0-60 faster than a stock Porsche. Now take both of those cars to a track and see what happens. AI does not change the fundamentals as much as you would think.

Why you choose a database still matters. It might not be because it has the best documentation or marketing or some sales guy brought you to dinner. But a database, for example, they're all fundamentally the same technology but they're all optimized for different use cases. So the flaw in this logic is being too abstracted and thinking too much of this stuff is the same. It's not. And there is a good reason for good quality code and there's a reason for bad quality code in certain domains.

AI is pushing things to such an incredible pace that you realize the good principles are required. The diligence is required. AI is going to drive the need for more smart individuals. More skilled individuals.

The PM playbook was built on an assumption that the technology underneath your product is roughly stable

With the current pace of model progress, this is no longer true. Here's how we've evolved the PM role:

🧵 I just reverse-engineered the binaries inside Claude Code's Firecracker MicroVM and found something wild:

Anthropic is building their own PaaS platform called "Antspace" (Ants + Space).

It's a full deployment pipeline — hidden in plain sight inside the environment-runner binary. Here's what I found 👇

MCPs are the opposite of dead. They are the life blood of how AI agents use services inside mid-sized and above companies.

Case in point: Uber runs on MCPs internally, for good reason. Details: https://t.co/gvLGq90qz0
