WEBVTT NOTE The Rundown — nextbig.dev daily audio edition, 2026-05-11 1 00:00:00.000 --> 00:00:02.215 Hey everyone, welcome to Builder's Briefing for May eleventh, twenty twenty-six. I'm Alex. 2 00:00:02.215 --> 00:00:06.422 And I'm Sam. We've got a packed one today — a huge runtime story, multimodal RAG from Google, some spicy opinions about AWS, and a few quick hits that are too fun to skip. 3 00:00:06.422 --> 00:00:12.721 Let's jump right into the big story. Bun — the JavaScript runtime that originally bet everything on Zig — has been quietly rewriting its core in Rust. And Jarred Sumner just announced they've hit ninety-nine point eight percent test compatibility on Linux. 4 00:00:12.721 --> 00:00:16.806 Okay, this is wild. When Bun launched, the whole identity was Zig — speed, low-level control, doing things differently. To pivot to Rust is a massive strategic shift. 5 00:00:16.806 --> 00:00:22.194 Right, and I think the key insight is it's not really about Zig versus Rust as languages. It's about contributor pool, long-term maintainability, and ecosystem leverage. Rust just has way more people who can contribute. 6 00:00:22.194 --> 00:00:29.281 That's the bus-factor argument, and it's legit. If you're shipping something that enterprises want to depend on, you need more than a handful of Zig experts maintaining it. And the fact that they hit near-perfect compat during a rewrite like this? That's seriously impressive engineering. 7 00:00:29.281 --> 00:00:37.622 The zero point two percent gap is mostly edge cases. So if you've been holding off on Bun in production because of concerns about the Zig ecosystem, those objections are basically gone now. And look at the bigger picture — Deno went full Node compat, Bun's going Rust for durability. The runtime space is consolidating around serious bets. 8 00:00:37.622 --> 00:00:42.445 Yeah, if you're starting a new project today, Bun just got a lot safer as a long-term choice. I'd expect their release cadence to speed up pretty significantly once the Rust port fully stabilizes. 9 00:00:42.445 --> 00:00:47.046 Alright, shifting to AI. Google dropped something really interesting — the Gemini API's file search now handles images, audio, and video alongside text for retrieval-augmented generation. 10 00:00:47.046 --> 00:00:50.368 Wait, so multimodal RAG natively? No more converting images to text descriptions and hoping your retrieval pipeline doesn't fall apart? 11 00:00:50.368 --> 00:00:55.732 Exactly. You can index and search across modalities directly. If you've been building these janky image-to-text preprocessing chains, this could simplify your whole pipeline. Link in the briefing if you want to try it. 12 00:00:55.732 --> 00:01:00.874 That's interesting because it changes what kinds of products you can build. Think customer support over screenshots, medical imaging retrieval, video knowledge bases — all stuff that was really painful before. 13 00:01:00.874 --> 00:01:07.321 The other AI story I want to flag is OMLX — it's an open-source agent that starts from about thirty-three hundred lines of code and literally grows its own skill tree. It achieves full system control while using six times fewer tokens than comparable approaches. 14 00:01:07.321 --> 00:01:14.752 Six times fewer tokens? Okay, for anyone burning money on agentic tool-use loops right now, that's not a marginal improvement, that's a fundamentally different architecture. The idea that the agent learns skills and caches them for reuse — that's the pattern I think we'll see everywhere in six months. 15 00:01:14.752 --> 00:01:19.747 Agreed. Now let's talk infrastructure, because there's a post with over four hundred points on Hacker News titled 'I Returned to AWS and Was Reminded Why I Left.' Three hundred forty-seven comments deep. 16 00:01:19.747 --> 00:01:24.988 Oh, I read that thread. It's cathartic if you've ever tried to untangle an IAM policy at two AM. The consensus is basically: AWS is unmatched at scale, but it's actively hostile to small teams trying to ship fast. 17 00:01:24.988 --> 00:01:31.312 The specific friction points everyone keeps hitting — IAM complexity, billing opacity, the console UX — it reads like a catalog of velocity killers for startups. If you're choosing infra right now, it's worth reading just to know what you're signing up for. 18 00:01:31.312 --> 00:01:37.685 And there's a great companion piece in today's briefing about idempotency edge cases — specifically when retry payloads mutate. If you're building payment flows or webhook handlers, that one will genuinely save you a production incident. Link in the briefing. 19 00:01:37.685 --> 00:01:41.769 On the dev tools side, a few things. Zed editor shipped a visual theme builder, which might sound small but it's the kind of polish that actually retains daily users. 20 00:01:41.769 --> 00:01:44.919 Honestly, that was one of my last excuses for not switching from VS Code. If I can bring my color scheme, I'm out of objections. 21 00:01:44.919 --> 00:01:49.421 Also loved the post about distributing Mac software being, and I quote, a 'cortisol generator.' Apple's signing and notarization process is apparently driving indie devs to the brink. 22 00:01:49.421 --> 00:01:53.580 I felt that in my soul. Anyone who's shipped a desktop Mac app knows the signing dance. It's reassuring and infuriating to know everyone else is struggling just as much. 23 00:01:53.580 --> 00:02:00.150 Quick security note — FreeBSD published a security advisory for a local privilege escalation in execve. If you're running FreeBSD in production — jails, firewalls, storage appliances — patch now. This is the kind of vuln that turns a low-privilege foothold into root. 24 00:02:00.150 --> 00:02:01.995 Yeah, don't sit on that one. That's a drop-everything-and-update situation. 25 00:02:01.995 --> 00:02:05.686 Alright, rapid-fire quick hits. Louis Rossmann and Bambu Lab right-to-repair drama is escalating with lawsuit threats against an OrcaSlicer developer. 26 00:02:05.686 --> 00:02:09.057 Oh no. The Internet Archive also opened a Swiss entity, which feels like they're hedging against US legal and political risk. Smart move. 27 00:02:09.057 --> 00:02:13.584 Someone built a web server in pure assembly — because why not. There's a Rust-with-Lisp-syntax experiment. And htmx is still trending on GitHub. The hypermedia moment just keeps going. 28 00:02:13.584 --> 00:02:17.718 Also a shoutout to the 'Making your own programming language' guide and the Visual Basic history that just dropped Chapter One. Those are weekend reads for the curious. 29 00:02:17.718 --> 00:02:24.312 So here's the throughline for today. The runtime and tooling layer is being rewritten in Rust. Bun is the biggest signal, but it's not the only one. If you're choosing foundational infrastructure or building developer tools, Rust-backed projects are the longevity bet. 30 00:02:24.312 --> 00:02:33.047 And on the AI side, multimodal RAG and self-evolving agents are the two patterns to watch. The next wave of AI products won't just call LLMs — they'll build persistent skill layers on top. If you're building agentic features, study the skill-tree pattern now. It's the clearest path to cutting token costs while improving what your agents can actually do. 31 00:02:33.047 --> 00:02:35.557 That's the briefing for May eleventh. All the links are in the show notes. Have a great week building. 32 00:02:35.557 --> 00:02:36.000 See you next time!
