There is no 10x RBAC

Infisical rebuilt permissions without Zanzibar by adding folder-based RBAC that supersedes role and group grants. They introduced five permission tiers (See, Read, Edit, Manage, Full) applied as Additional Privileges tied to folder IDs. To avoid breaking existing models, they kept legacy privileges and layered a denial block before allowed tiers, ensuring folder permissions win. They used CASL for checks and implemented a two-layer evaluation. Two-phase plan: standardize permissions first, then apply logic. Cache invalidation was solved with a per-project version counter that updates on any change. The goal: intuitive, reliable access control that handles contractor access and specializations.

Project Blinkenlights

Project Blinkenlights turns buildings into giant interactive displays. Begun in 2001 as the Chaos Computer Club’s birthday present, it has run installations on three continents. Notable works: Berlin 2001 (Haus des Lehrers, 18×8 monochrome); Paris 2002 (Bibliothèque nationale de France, 26×20, 8 greyscales); Toronto 2008 (Stereoscope, City Hall, 96×32, 16 greyscales). Reloaded (2004) and Bauschild followed; Polychrome since 2023 adds color. The project hosts galleries with original animations, a Movie Converter to GIF/WebP, and a press room with two decades of coverage; recent news includes Twitter drop, Nuit Blanche award, and a Toronto tech talk.

I spent $220 on Google app ads. 60% of the installs were robots

Dayzle founder spent CA$40/day (later CA$80) on Google Android ads and saw 21 installs in one day, but 20 came from a bot farm; the admin panel hid this because old app versions no longer report installs. Over two weeks, 56 billed installs: 33 bot-like, 13 real users who played 92 games. The bots used saved copies and quick ad views; Google counted a view+install as a conversion, boosting the bots’ visibility. Google is reviewing invalid traffic; the campaign’s goal was changed to 'won a puzzle' to deter fraud. The takeaway: verify install metrics beyond Google's numbers.

A Design Space Exploration of Async/Await

Gavin Gray’s Design Space Exploration analyzes async/await across seven runtimes and shows modern languages diverge more than expected. A small program that logs asynchronously yields four different outputs across languages, and no two runtimes agree on three variants. The paper introduces 'Eagerness' as a design dimension for how an async function starts (hot vs cold) and identifies nine dimensions—grouped into Start of Life, End of Life, and Cancellation—that shape semantics. It discusses dynamic extents, destruction, and cancellation, and presents a formal core calculus to explain divergences. The result: there are trade-offs; understanding semantics requires formal modeling.

ElevenLabs Music v2.5

ElevenMusic announces Music v2.5, the best music model yet, as the new default for prompted and reference generation. It delivers richer melodies, more natural instruments, and greater depth across genres. Tracks you create are yours, with ownership secured at creation and rights varying by plan. Free users get 5 lossless downloads per day; Pro users get 400 per month. Downloads are blocked for tracks referencing other artists’ songs. The update coincides with a separate multi-year licensing partnership between ElevenLabs and Universal Music Group.

CIA Releases President's Daily Briefs in Commemoration of 9/11

To commemorate the 25th anniversary of 9/11, the CIA declassified 71 President's Daily Briefs, the largest release of CIA PDBs on the topic, making more than 100 pages of analysis publicly available. Director John Ratcliffe called it an act of transparency under President Trump. The documents show CIA analysts' evolving understanding of al-Qa’ida and Usama bin Ladin’s plotting based on sparse information, covering before and after 9/11. The release honors those who were lost and CIA officers who served, reaffirming a commitment to disrupt, dismantle, and defeat those who threaten the United States.

Eating Fruit Skins

An essay exploring whether fruit skins and other parts are edible. The author discovers you can eat the whole apple—from flesh to core, and even the stem; seeds contain cyanide but aren’t risky in normal consumption. He notes deer eat whole apples and wonders why humans shouldn’t. He learns kiwi skins are edible and that strawberry stems are considered medicine in his community. A cautionary aside about horse chestnuts shows some foods that deer can eat but may sick people, clarifying that safety varies. Light, humorous observations on eating fruit skins.

GrapheneOS' rewritten Messages app is released

Release 13 of GrapheneOS Messaging is a complete UI overhaul using Jetpack Compose and Material 3, with a two-pane layout on large screens, new onboarding about SMS privacy and default apps, and an adaptive app icon. It rebuilds conversations and media flows: new bubbles, multi-select actions (archive, delete, block), pin/snooze/unread, status indicators, and a new recipient picker. Attachments, photos, vCard and sharing have refreshed pickers/viewers. Privacy/security improvements, crash/notification fixes, accessibility tweaks, and dependency upgrades (minSdk 36, target 37).

AlphaGenome maps 9B DNA variants

Google DeepMind's AlphaGenome model predicts how any single-letter DNA substitution may affect gene regulation. The AlphaGenome Atlas publicizes precomputed predictions for all 9 billion possible human genome variants, with a single-impact-score and 11 output types, enabling noncoding DNA analysis without coding. The 1-petabyte Atlas covers 1 million base pairs around each variant and aims to accelerate biology, disease research, and therapy development, though regulatory elements can act at longer distances and predictions are not definitive. Computation was accelerated via model distillation and GPU optimizations; Atlas is free for noncommercial research (licensing possible).

A misalignment of AI in mathematics

AI’s rapid progress in solving major mathematical problems risks misalignment with mathematics’ goals of deep understanding and careful human transmission. Rushing to publish solutions harms attribution, fosters plagiarism concerns, and undermines the gradual process by which ideas become textbook knowledge. AI can aid genuine study, but outcomes depend on human direction and societal choices. The mathematical community, tech companies, and broader society must urgently address these alignment issues; endorsements from leading mathematicians are invited.

The EPA Is Planning to Scrap Public Review Rules for Data Center Pollution

Federal EPA proposals would curb public participation in air-pollution permits for industrial facilities, including data centers, and allow construction before permits are approved. Critics warn this erodes community input, worsens health risks, and shifts costs to ratepayers, especially in rural Black communities where data centers are expanding. South Carolina already loosened review for power plants serving data centers. EPA argues the changes speed permitting and spur economic development. Advocates say communities could lose one of their few ways to learn about or challenge projects.

A Misalignment of AI in Mathematics

Terence Tao and 24 other Fields Medalists issue an urgent declaration warning that AI’s rapid mathematical problem-solving is misaligned with the aims of mathematics. While AI can aid understanding, using AI as a benchmark risks undermining rigorous, community-vetted methods, attribution, and the long human process of idea dissemination. Without careful governance by AI developers and society, AI could erode the mathematical canon and the transmission of knowledge. The signatories urge urgent discussion and responsible adaptation of mathematics to AI, acknowledging both risks and AI's potential benefits.

How I Prompt

Thorsten Ball shows how Amp builds coding agents with prompts, noting that 99% of the code is AI-written. The core idea is a mental model: the model can only understand you via training data, the context window (system prompts, tool definitions, conversation, results), the codebase, and your prompt. Effective prompts fuse multiple sources—folders, docs, Slack threads, screenshots, and prod data—and state constraints clearly. His 'one-two punch' first anchors the model in sources, then instructs specific tasks. He embeds guidance in code (agents.md), uses auto-generated debug prompts and screenshots to speed iteration. Focus on load-bearing components and docs for maintainability.
