Appeals court upholds FTX co-founder Sam Bankman-Fried's fraud conviction

An appeals court in the 2nd U.S. Circuit in Manhattan upheld Sam Bankman-Fried’s fraud conviction, ruling the 2023 trial was fair and the government’s evidence robust. It found he reassured FTX customers while siphoning billions for personal use and falsifying records to conceal transfers. Bankman-Fried, once a crypto titan, saw FTX collapse in 2022, leaving about $11 billion lost by customers, investors and lenders. His 25-year sentence follows the fraud and conspiracy convictions, with sentencing criticism centered on perjury and limited recoveries.

Euro-Office, open standards, and native ODF

Document Foundation welcomes Euro-Office’s open-standards pledge and improved ODF support, noting LibreOffice already exists as a European open‑source suite. It emphasizes sovereignty starts with the format, not branding, and that mere “support” is insufficient; documents must be created and stored in a native format. The expectation is for Euro-Office to adopt ODF as its native document format, speaking ODF as its mother tongue, not as a concession.

A PDF that changes based on who is reading

Adaptive PDFs attach replacement text to marked content in PDFs (PDF 1.4+) so text extractors return structured markdown instead of raw visual text, while rendering remains identical. Normal PDFs lack hierarchy; smart PDFs expose headings, lists, and tables via marked-content sequences. Humans see the usual layout; machines get clean markdown. Benchmarks show similar token counts but higher information density per token because structure travels with the text. PyMuPDF/Poppler and major LLMs reproduce markdown from smart PDFs. The concept yields Adaptive Documents—one file, two outputs—depending on reader, with plans for a Google Docs extension.

Malware developers added nuclear and biological weapons text to to their spyware

Malware developers have added nuclear and biological weapons text to spyware to trigger LLM safety refusals, aiming to avoid AI security scanners. This illustrates how over-indexing on first-order safety creates second-order blind spots attackers can exploit. We’re in the early days of attackers leveraging these features, and systems handling complex cybersecurity issues may demand less safety-blunted models. SocketSecurity’s post also shows why intention matters in malware-analysis pipelines to avoid prompt manipulation.

My Struggles Talking to an Old Piece of Junk (Fanuc 0M)

An author chronicles getting a 1990s Fanuc 0M on a Hermle UWF 851 up and running after months of learning from scratch, electrical work, and chasing alarms (1002 spindle alarm due to flaky limit switches, servo overload, axis detect errors, and a gear-change alarm from loose couplings). The machine now runs via MDI, but loading CAM programs via the serial port remains unresolved. After trying many adapter cables, they finally found a trio that works for data reception and wrote a Rust transpiler for an unfamiliar format; sending data still fails with 086 P/S ALARM (DR signal not seen).

WhatsApp Business API pricing 2026: what's free and where markup hides

The guide explains the WhatsApp Business API isn’t truly free. Meta charges per delivered message (rates vary by country and category); service messages within 24 hours are free, and the first 1,000 service conversations monthly are free. BSP and platform fees add to the cost. Since 2025 Meta shifted to a Cloud API, direct access can be free at the BSP layer, but platforms vary and many hide markups. Practical paths: use Meta Cloud API directly or self-host (Chatwoot) or try Wexio’s free tier. For small volumes, AiSensy or Chatfuel; for larger volumes, Wati or Respond.io. Verify real rates.

Wasi: WebGPU – A Proposed WebAssembly System Interface API

wasi-webgpu is a WebAssembly System Interface proposal for GPU access from WebAssembly. The repo outlines Phase 2 work for wasi:webgpu, with champions Mendy Berger and Sean Isom. Its goal is to bring Wasm’s portability and sandboxing to GPU compute. Use cases include server-side graphics streaming, scientific simulations, AI/ML inference and training, image/video processing, and data visualization. It explicitly excludes screen/windowing APIs. The API walk-through points to imports.md, and the design follows the WebGPU spec with deviations for non-web environments. The document covers use cases, detailed design considerations, alternatives, stakeholder feedback, and acknowledgments.

Where Did Earth Get Its Oceans? Maybe It Made Them Itself

Quanta surveys how Earth got its oceans. The comet theory faded after missions showed comet water differs in D/H from Earth's; Rosetta's 67P and Hartley 2 complicated the picture, while asteroid Ryugu yielded Earth-like water too. A newer idea proposes Earth-made water: under high pressure, hydrogen can react with a magma ocean to form vast amounts of water, potentially flooding a young world. Experiments by Horn and Shim show this could occur on sub-Neptunes and perhaps Earth-mass planets, though how much on Earth is uncertain. Most scientists favor a mix of sources.

A dumpster arrived behind my university's library

Liming recalls a university library’s deaccessioning and a dumpster of thousands of books, including half of Edith Wharton’s personal library, creating a “ghost” library that underscores the fragility of access to reading. Drawing on Derrida, she notes that the book is a medium through which the text persists, and that deconstruction reveals how reading is shaped by physical mediation. She argues that print libraries—shared, physical spaces—are crucial for deep literacy in an age of digital distraction and open resources; preserving libraries is a starting point, not a cure, to sustain reading.

Show HN: Script to bulk delete Claude chats from the web UI

GitHub project bulk-delete-claude-chat provides a JavaScript script (delete-all.js) to delete all claude.ai conversations at once by calling Claude’s internal API. To use: open claude.ai/recents, open the browser console (F12), paste delete-all.js, press Enter, and confirm for each organization. Conversations disappear gradually over minutes; keep the tab open until the console shows Finished, since leaving the page can halt the process. README covers purpose and usage.

Encrypted Spaces An architecture for collaborative applications

Encrypted Spaces envisions a collaborative data layer where data is encrypted and cryptographically verifiable on untrusted servers. It defines five components (membership state, a verifiable append-only database, key management, key retention, and application-defined operations) and prototypes a sync engine with Firebase/Supabase-like APIs backed by encrypted spaces. The goal is private, auditable collaboration with verifiable server behavior. Researchers Michele Orrù, Trevor Perrin, Nora Trapp, and Greg Zaverucha lead, collaborating with CNRS, Harvard Berkman Klein, and Microsoft Research. It is active research, not a shipping product.
