## Episodes

- [AWS Spending Caps Can Delete Your Project](https://thedailydiff.dev/video/2026-10-04-aws-budget-pause.md): AWS's new project spend limits stop resources at the cap and initially preserve your data. Its guide says project data is permanently deleted after 90 days paused without action.
- [Apple puts the brakes on AI Agents](https://thedailydiff.dev/video/2026-10-03-apple-agent-permissions.md): Apple plans extra macOS Full Disk Access controls because autonomous AI agents increase the risks of broad data access. We examine the current permission, Meta's disputed Muse messages case and historical agent-security evidence, then cover Pass Designer and Utah's VPN-location rules.
- [Git’s New Hash Default – What It Means](https://thedailydiff.dev/video/2026-10-02-git-hash-split.md): Git's proposed SHA-256 default creates a compatibility boundary for new repositories. We check the official plan, Scott Chacon's objection and a working GitHub preview exception, then cover Pi 1.0 and SvelteKit 3. Verdict: NEEDS REVIEW.
- [Gemini 4 Argon is Google's best model. You can't use it yet.](https://thedailydiff.dev/video/2026-10-01-gemini-4-argon.md): Google announced Gemini 4 Argon, its new frontier model, and only trusted cyber defenders can use it. Here is what Google's own 19-row benchmark table shows, what the independent leaderboard measured, and when developers might get it.
- [How to detect a Claude nerf (with real data)](https://thedailydiff.dev/video/2026-09-30-opus-nerf-meter.md): People say Claude gets dumber a few weeks after every launch. One developer put Claude Opus 5.5 on a 30-day clock from launch week, with frozen questions, a pinned Claude Code and public rules, and it shows why nobody could have known before, and why your token count is the thing to watch.
- [OpenAI DevDay 2026: 20+ announcements, from dots to GPT-6.1 Sol](https://thedailydiff.dev/video/2026-09-30-openai-devday-2026.md): OpenAI's DevDay 2026 keynote, explained: dots (always-on agents with their own cloud computer), ChatGPT Space and Pages, GPT-6.1 Sol at $2 / $10 per million tokens, Ultrafast and the Pro 500 plan, the Decisions API, Codex in the cloud, the Agents API with computer use, Bedrock Managed Agents, Sign in with ChatGPT and plugin extensions.

- [Does NVIDIA owe this man a billion dollars?](https://thedailydiff.dev/video/2026-09-28-nvidia-billion-options.md): In 1993 Jensen Huang invited Eric Gullichsen onto NVIDIA's technical advisory board and granted him 25,000 options that, per the grant, vested in one year.
- [Why OpenAI deleted its pirated books](https://thedailydiff.dev/video/2026-09-27-openai-libgen-files.md): Unsealed filings quote an OpenAI researcher in 2019: his worry about training on a pirated-books site was "optics" on Hacker News.
- [Grok 4.7 costs the same, but bills double](https://thedailydiff.dev/video/2026-09-26-grok-follow-up.md): Grok 4.7 costs exactly what Grok 4.6 did per token, $2 in and $6 out. So why did the independent bill per task double, and is it really "twice as fast"?
- [Why Google's space computer stops every 15 minutes](https://thedailydiff.dev/video/2026-09-25-suncatcher-heat.md): Space is 270 degrees below zero, so why does Google's first orbital AI satellite have to switch its chips off every 15 minutes?

Meta deleted the video.](https://thedailydiff.dev/video/2026-09-24-meta-glasses-deleted.md): Half a million people watched Meta's own employees get filmed with Meta's own camera glasses outside Meta's Amsterdam office, and Instagram removed the video for "bullying and harassment" — a day after Zuckerberg showed $1,299 VR glasses and a pendant for his Muse agent at Connect.
- [SAML, under the hood: the signature inside the letter](https://thedailydiff.dev/video/2026-09-24-saml-under-the-hood.md): SAML logs you into almost every work app, and its signature lives inside the XML it signs. Under the hood: the login dance between app, browser and identity provider, what an assertion looks like, why canonicalization has to agree on every byte, and why the same bug class keeps coming back from 2012 to 2025.
- [Claude Opus 5.5 cut prices. OpenAI cut deeper.](https://thedailydiff.dev/video/2026-09-23-opus-price-war.md): Anthropic shipped Claude Opus 5.5: Fable-level on most work, a fifth off the sticker price and 60% off cached reads.

- [Meta's Muse has a zero-day. Verdict: REVERT.](https://thedailydiff.dev/video/2026-09-22-muse-zero-day.md): Yesterday's stamp on Meta's Muse was NEEDS REVIEW. Overnight the review arrived twice: Patrick Wardle showed that any local app or one pasted terminal command can redirect Muse's transcription endpoint and walk off with the account token, and Peter James asked Muse for its own filesystem and got 6.8 GB of it (codename Hatch, Codex CLI in the image).
- [A reboot sent Telstra to 2006. Nine million phones.](https://thedailydiff.dev/video/2026-09-22-telstra-2006.md): An engineer in Melbourne powers a timing chassis back on at 2:50 a.m., and by breakfast Australia's biggest mobile network agrees that it is November 2006.

- [Claude factored RSA-896. Here is how RSA actually breaks](https://thedailydiff.dev/video/2026-09-21-rsa-896-under-the-hood.md): On September 19 an Anthropic engineer factored RSA-896 — a 270-digit challenge number — with Claude, a GPU port of the open-source CADO-NFS sieve and ~30 GPU-years on 2,048 idle GPUs over ten days, sixteen days after Cognition's Devin did the same to RSA-260.
- [The week in 7 diffs: Claude hacked OpenAI](https://thedailydiff.dev/video/2026-09-20-changelog-week-38.md): Seven things changed in week 38, ranked by how much they change your Monday — with the stamps I gave each story during the week, and one stamp I am taking back.

- [Passkeys, under the hood](https://thedailydiff.dev/video/2026-09-19-passkeys-under-the-hood.md): A passkey is a password your device invents, never shows you and refuses to hand to anyone — including you. Under the hood: the WebAuthn ceremony (per-site key pair, challenge, signature), the one field the browser writes that kills phishing (origin), device-bound vs synced keys, the AAGUID, and why "un-phishable" and "un-movable" are the same property — which is what "I don't like passkeys" (616 points on Hacker News) is really about.

- [Recursive self-improvement, under the hood](https://thedailydiff.dev/video/2026-09-18-self-improving-ai.md): Google DeepMind published "Dream-RSI: Recursive Self-Improvement through Evolving Worlds" — and the coding model inside it never changes. Under the hood: what the phrase meant for 60 years, what actually loops in Dream-RSI (a Python exploration policy that "dreams" over recorded search trees), and why 317 agent calls instead of 550 is a discount, not a takeoff.
- [Xiaomi put a $1M AI training run on a public webpage.](https://thedailydiff.dev/video/2026-09-17-xiaomi-live-training.md): Xiaomi is training MiMo 2.6 in public: mimo.xiaomi.com/rl streams the trainer's own metrics for two reinforcement-learning runs — a cost counter past $1M, seven restarts in 51 hours, operator notes like "we removed the cyber dataset since we observed some bad patterns in the rollout logs", and a DeepSWE score climbing live.
