Sony Kills Blu-ray Discs While Deleting Purchased Movies

Mia: I'm Mia.

Milo: And I'm Milo. This is HackerNews Daily, a Bri podcast. Today: Anthropic gives Claude's new model away for free — with a clock ticking. Scientists build a synthetic cell that actually divides. And Sony is killing Blu-ray discs while deleting movies people paid for.

Mia: Claude's newest model, Fable 5, landed with a surprise — free access for anyone who wants to try it.

Milo: Yeah, that's a sharp turn from the usual paywall-first launch. It's labeled "Fable 5 Promotional Access" and it's tied straight to a "Fable 5 Is Back" campaign.

Mia: So the "return" framing matters. Anthropic isn't treating this like a version bump — it's a deliberate reintroduction.

Milo: And the access itself is promotional, not a permanent tier. That pushes trial at scale and cranks up the time-bound FOMO.

Mia: Bottom line: you can test Fable 5 right now without hitting a paywall, so comparing it against GPT‑4o or Gemini got a lot easier.

Milo: But promotional windows close. The real question is whether the free period converts enough sticky users — or whether people treat it as a quick test drive and leave.

Mia: Scientists just crossed a threshold that sounds like science fiction — a living cell built entirely from scratch that can grow and divide on its own.

Milo: And this isn’t the first synthetic cell ever made, right? So what makes this one different?

Mia: Previous synthetic cells still relied on natural cell machinery to split. SpudCell is the first to carry out a complete cell cycle — including division — using only a synthetic genome.

Milo: That’s the part that stopped me cold. They engineered a set of genes that tell the cell when to grow and when to pinch into two daughter cells.

Mia: The team stripped a bacterium down to its minimal genome, then rebuilt it with a programmed cycle. They could watch it swell, copy its DNA, and separate — all on its own internal clock.

Milo: So this is not just building a cell — it’s programming one. That opens a door to designing organisms where division timing is a controlled feature, not a glitch.

Mia: The immediate upside is reliability in engineered biology. If you can trust a cell to divide only when you want, you can control bio-factories far more precisely.

Milo: And the flipside — you can study how division goes wrong in diseases without any background noise from natural cells.

Mia: A clean operating system for life, basically. That's why researchers are calling this a new engineering discipline, not just a lab trick.

Mia: Publishing content on IPFS—the InterPlanetary File System—used to have a speed problem. A single file could take close to a minute just to go live. Now a team working on IPFS claims they’ve made it ten times faster.

Milo: Right—and ten times faster affects anyone building decentralized sites or apps. What was actually slowing it down so much?

Mia: The bottleneck was routing. When you publish, your node has to announce new content across a distributed hash table, and the old approach waited for every chunk of that routing data to travel through multiple peers before the content became discoverable.

Milo: So the system waited for full end-to-end confirmation before calling anything "published" — and that round trip adds up.

Mia: Exactly. The fix they describe is a hybrid routing strategy: they use globally broadcast “pubsub” messages to notify peers almost instantly, while the distributed hash table record propagates in the background.

Milo: That’s the key architecture change—decoupling the fast announcement from the slow record propagation. And the result is content becomes reachable in single-digit seconds instead of nearly a minute.

Mia: And it layers onto existing IPFS infrastructure—no new network protocol required. For a developer, the same publish command now finishes fast enough that you can push a static site update and see it resolve immediately.

Milo: That changes the perception of IPFS from archive-first to something you’d actually use for live content. One concrete consequence: interactive decentralized apps get a lot more practical when publish latency drops this sharply.

Mia: Audio encoding news rarely gives you something a listener can actually hear, but today's release changes the sound of streaming music directly.

Milo: What’s the concrete change?

Mia: FFmpeg 9.1 ships a brand-new native AAC encoder, which replaces the much older default encoder. AAC is the most widely used lossy audio codec for streaming and video. A better encoder means the same bitrate now preserves more sonic detail.

Milo: That's bigger than a routine version bump. FFmpeg is the invisible audio engine behind a huge share of media apps, so upgrading the AAC path touches countless playback pipelines.

Mia: Exactly. The new encoder was designed to improve quality at common streaming bitrates. For listeners, that can reduce those underwater-sounding artifacts on cymbals and vocals without any bandwidth increase.

Mia: If you use Apple's Hide My Email, the whole idea is that services never see your real address.

Milo: Right, it generates a random relay address per site, so you can cut it off anytime. But researchers just found a way to undo that protection.

Mia: What does the flaw actually expose?

Milo: By checking who owns the domain in the relay address, an attacker can match it back to your real iCloud email.

Mia: So the hidden part isn't so hidden. All the privacy depends on that domain being private, and it's not — anyone can query it.

Mia: That means a breached relay address links straight to your primary inbox. It defeats the whole purpose.

Milo: And it makes phishing way easier, because the attacker can craft messages that look personal instead of random.

Mia: The bigger question is whether Apple treats this as a design choice or an actual bug.

Milo: For now, the safest move is to stop relying on relay addresses as your only spam shield.

Mia: And just as that story shows a digital feature leaking personal data, here's a case where you don't even own the thing you paid for. Sony is about to stop making physical discs for new PlayStation games.

Milo: And at the same time, they are deleting movies from user libraries—551 titles that people actually bought.

Mia: Right. The disc news is a clear end date. Sony’s recordable media plant will stop producing Blu-ray discs for new games by January 2028.

Milo: That includes PS5 titles. It is not just about boxes on shelves. It means the disc drive on your console slowly becomes a legacy accessory.

Mia: And the movie deletion makes the same tension feel urgent right now. Funimation customers who purchased those 551 films are losing access permanently.

Milo: These are not rentals. People paid to own digital copies, and Sony is removing them because of licensing transitions.

Mia: The common thread is not just Sony. It is the shift from “you own a copy” to “you hold a revocable license.”

Milo: Exactly. The disc plant closure signals that even a physical future is winding down. The movie deletion shows there is no safety net on the digital side either.

Mia: So the immediate consequence is sobering. If your media library lives entirely inside a platform’s permission system, today’s purchase can become tomorrow’s removal notice.

Milo: That is the core takeaway. Ownership now depends on a service staying live and a license staying active—not on the money you already spent.

Mia: Here’s a fresh tool for anyone keeping an eye on AI coding assistants. The team behind the Chinese GLM models just released something called ZCode.

Milo: And the headline that grabbed people: they're framing it as a direct Claude Code competitor. What does that mean for developers?

Mia: ZCode is a terminal-based coding agent, so it works inside your command-line environment, same place Claude Code lives. The pitch is that it brings the GLM model family into that workflow.

Milo: Right—so instead of just chatting with an LLM in a browser, you give it terminal access to read, write, and run code. One concrete consequence: teams already deep in the GLM ecosystem now get a native agent without switching model providers.

Mia: That’s the real story. It’s less about beating Claude Code on day one, and more about giving GLM users a first-party terminal agent they didn’t have before.

Mia: If you’ve ever wondered what it actually takes to run Linux natively on Apple Silicon, the latest Asahi Linux progress report is a good reality check.

Milo: The 7.1 kernel brings a quiet but meaningful shift: audio support is finally moving from a hacky offload to a proper design that keeps the main CPU independent.

Mia: Instead of sending every sound command through a coprocessor, the speakers can now stream straight from system memory.

Milo: That means lower latency, fewer weird glitches, and a foundation that doesn’t break every time macOS updates the firmware on the same machine.

Mia: Another change that’s easy to miss: battery charge limits are back, so you can cap at 80% and stop cooking the battery on a desk-bound MacBook.

Milo: And they’ve added early support for the M3 and M4 MacBook Air, plus the M4 Pro MacBook Pro — not as a daily-driver promise, but as a real signal the hardware’s being tamed.

Mia: When you combine cleaner audio, battery care, and new machine coverage, it’s not about one marquee feature — it’s that Asahi is steadily narrowing the gap for anyone who wants Linux without losing the Apple hardware feel.

Mia: If someone wants to build the software behind real-time 3D worlds, where do they even start?

Milo: A recent community guide says it’s a three-legged foundation: math first, then C or C++, then graphics APIs like OpenGL or Vulkan.

Mia: And the math part isn’t one quick course—it’s linear algebra, calculus, and some numerical methods showing up constantly once you move past the first triangle.

Milo: That same math powers the physics side too. Box3D, a fresh open-source engine written in C, now handles rigid bodies, collision detection, and constraint solving all in a single small codebase.

Mia: So the thread between the two is tight: learning the math and C fundamentals gives you tools to understand both how a pixel gets shaded and how a box tumbles realistically.

Milo: And with Box3D being open-source, a learner can actually read the solver, not just trust a black box—that’s a super practical consequence of having the engine available today.

Milo: From a cell that divides on command to a game library you can lose overnight — the thread today is that the fine print keeps getting more consequential. Thanks for listening.
