First Complete Herculaneum Scroll Read Using AI ⭐️ 9.0/10

The Vesuvius Challenge team has successfully read an entire Herculaneum scroll for the first time, using machine learning and CT scanning to reveal ancient Greek text from carbonized papyri. This breakthrough demonstrates that AI and advanced imaging can unlock vast amounts of ancient texts previously thought unreadable, potentially recovering lost works of classical literature and philosophy. The scans were performed using high-resolution phase-contrast X-ray microtomography at the European Synchrotron Radiation Facility (ESRF), and the team also unwrapped 140 columns of new text from another scroll (PHerc. Paris. 4).

Background: The Herculaneum papyri are over 1,800 carbonized scrolls discovered in the 18th century at the Villa of the Papyri, buried by the eruption of Mount Vesuvius in 79 AD. They contain Greek philosophical texts, including works by the Epicurean philosopher Philodemus. The Vesuvius Challenge is a competition that uses machine learning and computer vision to read these fragile scrolls without unrolling them.

References:

Discussion: Community members expressed awe at the achievement, with one noting the profound historical connection across millennia. A team member offered to answer questions, and another revealed that 140 columns of new text were also unwrapped from a different scroll. Commenters also highlighted the potential for discovering more scrolls in unexcavated parts of Herculaneum.

Age Verification Mandates Threaten Online Privacy ⭐️ 8.0/10

An article warns that government-mandated age verification for internet access will erode privacy by forcing users to hand over identification documents to countless websites. This matters because age verification laws are spreading globally, and if implemented poorly, they could create a surveillance infrastructure that tracks every online interaction, affecting all internet users. The article highlights that current age verification methods often require uploading a photo ID, which creates risks of data breaches and profiling, but cryptographic solutions like anonymous credentials can prove age without revealing identity.

hackernews · bilsbie · Jun 25, 21:44 · Discussion

Background: Anonymous credentials are cryptographic tools that allow a user to prove attributes (e.g., age over 18) without revealing their identity or linking multiple verifications. They are being developed by standards bodies like IETF and could enable privacy-preserving age verification.

References:

Discussion: Commenters debate the trade-offs: some advocate for anonymous credentials as a technical solution, while others question whether children need constant internet access at all. There is skepticism that governments truly care about privacy, and some users plan to opt out entirely.

IBM Unveils World’s First Sub-1nm Chip Technology ⭐️ 8.0/10

IBM announced the world’s first sub-1 nanometer (0.7nm / 7 angstrom) chip technology, featuring a new transistor architecture called nanostack that enables nearly 100 billion transistors on a chip the size of a fingernail. This breakthrough demonstrates that semiconductor scaling can continue into the atomic era, potentially enabling more powerful and efficient chips for future computing needs. However, the industry has decoupled node names from physical dimensions, so the actual transistor size may not be 0.7nm. The 0.7nm node achieves nearly double the transistor density of IBM’s 2nm chip announced in 2021, enabled by innovations in wafer bonding, SRAM scaling, and channel materials. The technology is still in the research phase and not yet in commercial production.

hackernews · porridgeraisin · Jun 25, 15:33 · Discussion

Background: In semiconductor manufacturing, node names like ‘7nm’ or ‘3nm’ historically referred to specific transistor dimensions, but over the past decade they have become marketing terms loosely tied to density improvements. IBM’s announcement continues this trend, with the ‘0.7nm’ label indicating a generational advance rather than literal atomic-scale features.

References:

Discussion: Community comments are highly skeptical, noting that node names no longer correspond to physical dimensions and that IBM has a history of exaggerated marketing claims. Some users pointed out that IBM paid GlobalFoundries to take over its fabs, questioning its manufacturing credibility. A link to a detailed technical analysis was also shared.

Oral History of Bank Python Systems ⭐️ 8.0/10

An oral history article published in 2021 details the unique, internally-developed Python-based systems used in investment banks, tracing their origins from Goldman Sachs’ SecDB/Slang to JPMorgan’s Athena and Bank of America’s Quartz. This account provides rare insight into a niche but influential ecosystem that powers critical trading and risk management operations, highlighting why banks built custom solutions instead of using off-the-shelf software. The systems often predate modern open-source alternatives, leading to software archaeology challenges; for example, the Barbara system stores its own source code in a special ring called ‘sourcecode’ rather than on disk.

hackernews · tosh · Jun 25, 20:14 · Discussion

Background: Investment banks developed proprietary trading and risk management platforms internally due to the lack of mature off-the-shelf solutions at the time. These systems, often built on Python, evolved from earlier languages like Slang (a C-like language used at Goldman Sachs). The article is an oral history capturing the experiences of engineers who built and maintained these systems.

Discussion: Commenters note the lineage from Goldman’s SecDB/Slang to JPMorgan’s Athena and Merrill’s Quartz, and emphasize that these systems were written before modern alternatives existed, making attempts to rewrite them in smaller firms frustrating. One commenter highlights the unusual practice of storing source code within the system itself.

AI Agents Should Be Treated as Agents of Deployers ⭐️ 8.0/10

Bruce Schneier argues that AI agents should be legally treated as agents of their deployers, citing a landmark German ruling that held Google liable for errors in its AI Overviews. This principle could prevent companies from escaping liability by blaming AI errors, ensuring accountability and fair incentives for responsible AI deployment. The German ruling classified Google’s AI Overviews as the company’s own editorial content, making it directly liable for false or defamatory statements generated by the AI.

rss · Simon Willison · Jun 25, 22:28

Background: AI agents are systems that can autonomously perform tasks on behalf of users or organizations. Traditionally, companies are liable for mistakes made by human employees, but AI introduces ambiguity about who is responsible when an AI errs. This ruling sets a precedent that AI outputs are the deployer’s responsibility, similar to human agents.

Aggressive Tool Result Pruning Maintains Agent Reasoning Quality ⭐️ 8.0/10

Jakevin7 challenges the common assumption that tool results must be fully retained for agent reasoning, showing that aggressive pruning of tool results in the Maka agent reduces token usage by 62% while maintaining nearly identical inference quality. This insight could significantly reduce token costs and improve efficiency for long-running agent tasks, challenging the conventional wisdom in agent engineering and potentially reshaping how context windows are managed. In a MIPS interpreter task, Maka’s total token consumption was only 38% of OpenCode’s, while output tokens were 2.7 times higher, partly due to tool result pruning and DeepSeek’s 95% cache hit rate.

twitter · kabikabi · Jun 25, 06:43

Background: In AI agent loops, tool results (e.g., code output, API responses) are typically kept in full for the model to reference in later reasoning steps. The ‘Lost in the Middle’ phenomenon shows that transformer attention decays for middle-positioned content, making long tool results less useful. Semantic distillation occurs when the model’s own assistant message after a tool call already captures the essential information.

References:

Discussion: The discussion (72 replies) likely includes diverse viewpoints, with some agreeing on the efficiency gains while others may caution about loss of information for complex multi-step tasks. The post’s high score (8.0) indicates strong community interest.

Un-0: Image Generation via Coupled Oscillators ⭐️ 7.0/10

Unconventional AI has introduced Un-0, an image generator that uses a simulated system of coupled oscillators to produce images, achieving an FID of 6.74 on ImageNet 64×64, matching early leading conventional methods. This approach offers a potential path to dramatically lower energy consumption in image generation, as coupled oscillators could be implemented in analog hardware for 1,000x energy efficiency gains. The current implementation is a digital simulation, so the energy benefits would only be realized with a dedicated analog chip; scaling to high-resolution images like 4K would require trillions of connections, posing a major challenge.

hackernews · babelfish · Jun 25, 20:50 · Discussion

Background: Coupled oscillators are physical systems where oscillators influence each other’s phase, and phase differences can encode information. Analog computing uses continuous physical quantities (e.g., voltage) rather than discrete bits, potentially offering higher energy efficiency for certain tasks.

References:

Discussion: Commenters expressed interest in analog computing but raised concerns about n² scaling for high-resolution images and noted that the current simulation doesn’t yet deliver the promised energy efficiency. Some drew parallels to FM synthesis and historical analog computers.
