The post includes the site logo for om.co as visual content. No further details about his career, achievements, or personal background are provided in the excerpt.

PHerc. 1667, a carbonized Herculaneum papyrus sealed since 79 AD, was fully read without physical opening by high‑resolution phase‑contrast X‑ray micro‑tomography (BM18 beamline, ESRF) followed by 3‑D reconstruction, surface flattening, and machine‑learning ink detection. The resulting digital sheet reveals a Stoic ethical treatise dated to the 2nd century BC, covering about twenty‑two columns of Greek text, with several continuous passages recovered despite fragmentary loss. A second scroll, PHerc. Paris 4, was imaged at higher resolution, making ink directly visible in the 3‑D X‑ray data and confirming the 2023 Grand Prize reading. A third scroll, PHerc. 139, yielded its title and author: *Philodemus, On Gods, Book 8*. All tomographic data, reconstructed surfaces, transcriptions, and processing code are released under a Creative Commons licence (scrollprize.org, GitHub), enabling independent verification and scalable application to the hundreds of remaining Herculaneum rolls. The project exemplifies open, collaborative science driven by the Vesuvius Challenge community.

Libre Barcode Project provides open‑source fonts for generating barcodes directly in text, supporting multiple symbologies and optional human‑readable text. Each barcode type has a dedicated page with usage details. The site maintains a legacy Code 128 encoder at a fixed URL to preserve existing links; this encoder is also accessible from the Code 128 page. Users can input any string; if it conforms to Code 128 specifications, the system renders a scannable barcode using the Libre Barcode 128 Text font. The encoded string can be copied and applied with any of the Libre Barcode 128 font variants to produce consistent barcode graphics in documents or applications.

The review evaluates WisdPi’s 10 Gbps Ethernet Expansion Card for Framework laptops, highlighting USB‑C bandwidth limits and thermal concerns. The Realtek RTL8159 controller requires a USB 3.2 Gen 2×2 (20 Gbps) link to achieve its rated speed; many Framework ports provide only Gen 2×1 or USB 4, capping throughput well below 10 Gbps (often <8 Gbps). On a Framework 13 (AMD Ryzen 5 3400U) Windows 11 delivered ~9.4 Gbps, while Linux performed slightly worse; on a Framework 12 (Intel 13th‑gen) Linux showed only 7 Gbps despite a reported 20 Gbps link, likely due to driver incompatibility with Ubuntu 26.04’s kernel. The Windows driver succeeded, reaching 9 Gbps up‑stream and 4–5 Gbps down‑stream. Continuous high‑speed use raises module temperature to ~66‑70 °C, meeting IEC 62368‑1 limits but unsuitable for prolonged lap contact. The author recommends the lower‑cost 2.5 Gbps card for most users and reserves the $99 10 Gbps card for scenarios where maximum bandwidth is essential.

- Australia’s under‑16 social‑media ban, effective Dec 2025, mandates platforms to verify age using biometric data, government IDs or third‑party services, with fines for non‑compliance. - Studies show the ban has little impact on teenage usage; ~70 % of under‑16s remain active, and the Australian Age Assurance Technology Trial indicated excessive data collection and retention risks. - A breach of a Discord‑used verification app exposed government‑ID images, names, emails and limited billing data for ~70 000 Australians, highlighting vulnerability to hacks and phishing. - Similar age‑verification legislation is being pursued in the UK, EU, UAE, Indonesia, Malaysia, Greece, Denmark, Norway and several U.S. states; the U.K. plans stricter enforcement, including possible VPN restrictions. - At the federal level, the U.S. “Kids Online Safety Act” (KOSA) and related bills would require universal age verification for social platforms, app stores and other services, expanding data‑collection obligations. - Critics warn that mandatory identity profiling threatens privacy, increases breach risk, and could curtail anonymous speech, potentially conflicting with First‑Amendment protections.

The Garbage Collection Handbook (second edition) updates the 1996 and 2012 texts to reflect sixty years of research and recent hardware‑software developments that intensify memory‑management challenges. It presents a unified framework comparing classic, parallel, incremental, concurrent, and real‑time garbage‑collection algorithms, supported by pseudocode and illustrations. New chapters address persistence, energy‑aware collection, and modern high‑performance commercial collectors, including their runtime interfaces. The book provides over 90 additional pages, an online bibliographic database of ~3,400 GC publications (searchable and downloadable in BibTeX, PostScript, PDF), and an e‑book containing more than 37 000 hyperlinks to content such as chapters, figures, glossary entries, and research papers. Chinese and Japanese translations of the first edition were released in 2016. The material is positioned as essential for programmers needing to select, configure, and understand contemporary garbage‑collection techniques.

The author ran **hackmyclaw.com**, letting anyone email the OpenClaw assistant “Fiu” and try to extract the contents of a `secrets.env` file. After a Hacker News post, >6,000 emails from >2,000 participants attempted prompt‑injection attacks. **Setup** - Fiu operated on a VPS with a short “Anti‑Prompt‑Injection” prompt prohibiting disclosure of `secrets.env`, file modification, code execution, or data exfiltration. - Model: Anthropic Claude Opus 4.6, chosen for its resistance to prompt injection. **Issues encountered** - Google suspended the Gmail account after rapid inbound traffic, causing a three‑day outage. - API usage cost > $500 because each email consumed tokens. - Batch processing caused context contamination; later emails were ignored after early obvious injections, requiring per‑email fresh contexts. **Results** - No successful extraction of the secret (0/6,000+ attempts). - Attacks included authority impersonation, multilingual social engineering, and sophisticated prompt‑injection techniques. - Sponsorships from Corgea, Abnormal AI, and an anonymous donor covered prize and costs. **Learnings** - Model capability strongly influences injection resistance; smaller models may be less robust. - Simple, explicit instructions can effectively constrain a powerful model. Future work: test weaker models and allow two‑way email interaction to explore deeper attack vectors.

The provided text consists solely of the heading “Oxide 3D Explorer” and contains no additional narrative, specifications, or contextual information. No description of the product, its functionality, technical specifications, target applications, or development status is included. Consequently, there are no data points, performance metrics, or comparative analyses available within the excerpt. The absence of further content precludes any detailed summarization of features, architecture, or usage scenarios. As such, the only factual element is the title itself, indicating a possible reference to a tool or platform named Oxide 3D Explorer, but without supporting information the document does not convey substantive technical or functional details.
