Verus is a tool for verifying the correctness of code written in Rust
13 hours ago
- Verus is a static verification tool for Rust code that uses theorem proving to ensure functional correctness without runtime checks.
- It combines a mathematical language for specifications and proofs with Rust's syntax and type system, leveraging SMT solvers like Z3 for efficient verification.
- The tool focuses on high-value Rust features, avoids verifying itself or compilers, and requires user knowledge of Rust, with guides covering basic to advanced proof techniques.
The Hero's Journey Is Burning the Planet
4 hours ago
- Elon Musk, Sam Altman, and Mark Zuckerberg are all following the same mythological pattern, the hero's journey, which explains why they build similar products like AGI despite different backgrounds.
- The hero's journey, as defined by Joseph Campbell, is a monomyth where a hero goes on an adventure, faces trials, seizes a prize, and returns transformed. However, tech founders invert this by hoarding the 'elixir' (the prize) instead of sharing it with the community.
- The convergence on building AGI and other products (e.g., Mars colonization, the metaverse) isn't driven by market demand but by the mythological quest for transcendence, control, and escaping the 'feminine' (nature, the body, connection).
- The origins of Tesla, OpenAI, and Facebook are fabricated to fit the hero narrative, often involving seizing control from actual founders or starting with unethical actions (e.g., FaceMash).
- Women like Mira Murati, Elizabeth Holmes, and Sheryl Sandberg also run the hero's journey, producing similar harms, proving the pattern is about mythology, not gender.
- Beneath the hero's journey lies an older myth, the Enuma Elish, where Marduk kills the mother goddess Tiamat and builds the world from her corpse—this symbolizes killing nature/generative femininity to create controlled, extractive systems.
- The hero's journey lacks a mechanism for stopping or returning to community, leading to perpetual growth, environmental harm, fraud, and exploitation, as seen in tech's hyperscaling and harms disproportionately affecting women.
- Regulation and ethics boards fail because they address outputs, not the underlying mythological algorithm that structurally produces these harms; the solution requires an alternative, older journey focused on reassembly and wholeness.

Berea college makes tuition free with its endowment
3 hours ago
- Berea College, founded in 1855 in Kentucky, has not charged tuition since 1892 and provides every student with a job through a comprehensive labor program, covering costs like housing and living expenses.
- The college is tuition-free thanks to a $1.2 billion endowment, with over 90% of students eligible for Pell Grants, primarily from low-income Appalachian backgrounds, and boasts a diverse student body with over 40% racial minorities.
- Berea faced a tax threat in 2017 from a Republican-led reform that would have taxed large endowments, but was exempted after bipartisan backlash, highlighting the unique nature of its model compared to wealthier institutions like Harvard.
- Founded by abolitionist John G. Fee, Berea was the South's first integrated, co-educational college, but was forced to segregate in 1904 due to Kentucky's Day Law, only reintegrating in the 1950s, and has since rebuilt its commitment to diversity.
- The college's financial stability relies heavily on endowment investment earnings (75% of its budget), raising concerns about sustainability during economic downturns, though it prioritizes avoiding tuition charges to maintain its identity.
- While Berea's model is hard to replicate due to its century-long development, elements like work programs have been adopted by other colleges, though going tuition-free remains a challenge for most institutions.

Using Changesets in a polyglot monorepo
3 hours ago
- Monorepos offer advantages for small-to-medium teams, such as enabling atomic changes across the system in a single commit, which reduces compatibility and integration issues.
- Changesets is a viable tool for managing versioning in polyglot monorepos, even with its primary focus on JavaScript/TypeScript, by leveraging custom scripts via its GitHub Action for polyglot support.
- Setting up changesets involves using proxy package.json files for all packages to handle version bumps, with configuration files like .changeset/config.json to control behavior such as private package tagging.
- Automated releases can be implemented using a GitHub workflow that calls custom scripts (e.g., just version) to sync versions from package.json to native manifests (e.g., Cargo.toml, pyproject.toml) for different programming languages.
- Instead of relying on on.push.tags triggers, which can be unreliable in GitHub, use workflow_call to react to package tags for building artifacts like Docker images, ensuring consistent and reliable automation.
Corner-Case RCU Implementations
a day ago
- RCU can be implemented with a fixed time grace period, like a 15-second wait, used in hard real-time systems and past production.
- Timed-wait RCU is risky but has been used for performance, including by Van Jacobson and in DEC OSF/1, though not recommended outside real-time.
- Fixed-buffer RCU uses space (e.g., quarantined memory) for grace periods, seen in KASAN and rcutorture for bug detection, but could be repurposed.
- Both timed and buffer-based RCU show RCU can rely solely on time or space, unlike standard RCU which combines both for synchronization.
- Historical examples highlight trade-offs: admin accepting buggy patches for performance and a past RCU bug unnoticed due to insufficient testing.
Types and Neural Networks
4 hours ago
- Neural networks currently generate code in typed languages, but LLMs are trained to output raw tokens, not typed structures, relying on post-hoc typechecking.
- Two main post-training approaches are retry loops (low granularity, high bandwidth) and constrained decoding (high granularity, low bandwidth), both of which are inefficient and don't update model weights.
- Integrating type systems into training, as seen in AlphaZero for chess, could dramatically improve performance by enabling models to learn structural rules, unlike current methods.
- Differentiating through structure, as in CHAD, fixes output types but prevents learning the structure itself, requiring predefined partitions.
- Differentiating with respect to structure allows models to learn type choices via distributions, producing well-typed output and enabling gradient-based learning of structured outputs.
- This approach leverages containers and dependent lenses to handle complex types uniformly, promising more meaningful and efficient code generation.
- Scaling on structured representations, rather than flat tokens, aligns with encoding domain rules into training for better performance, as demonstrated in chess.

The Hero's Journey Is Burning the Planet
4 hours ago
- Elon Musk, Sam Altman, and Mark Zuckerberg are all following the same mythological pattern, the hero's journey, which explains why they build similar products like AGI despite different backgrounds.
- The hero's journey, as defined by Joseph Campbell, is a monomyth where a hero goes on an adventure, faces trials, seizes a prize, and returns transformed. However, tech founders invert this by hoarding the 'elixir' (the prize) instead of sharing it with the community.
- The convergence on building AGI and other products (e.g., Mars colonization, the metaverse) isn't driven by market demand but by the mythological quest for transcendence, control, and escaping the 'feminine' (nature, the body, connection).
- The origins of Tesla, OpenAI, and Facebook are fabricated to fit the hero narrative, often involving seizing control from actual founders or starting with unethical actions (e.g., FaceMash).
- Women like Mira Murati, Elizabeth Holmes, and Sheryl Sandberg also run the hero's journey, producing similar harms, proving the pattern is about mythology, not gender.
- Beneath the hero's journey lies an older myth, the Enuma Elish, where Marduk kills the mother goddess Tiamat and builds the world from her corpse—this symbolizes killing nature/generative femininity to create controlled, extractive systems.
- The hero's journey lacks a mechanism for stopping or returning to community, leading to perpetual growth, environmental harm, fraud, and exploitation, as seen in tech's hyperscaling and harms disproportionately affecting women.
- Regulation and ethics boards fail because they address outputs, not the underlying mythological algorithm that structurally produces these harms; the solution requires an alternative, older journey focused on reassembly and wholeness.

How a subsea cable is repaired
5 days ago
- Submarine cables are categorized into data cables (fiber optic) and power cables (AC/DC), with differences in design, protection, and application.
- Cable damage often results from human activities like fishing trawlers and anchor drops, though natural events like earthquakes or shark bites can also cause breaks.
- Repair starts by locating the break via signal reflection for data cables or ROVs for power cables, followed by dispatch of specialized cable ships.
- Shallow-water repairs use ROVs to retrieve cables, while deep-water repairs involve cutting and surfacing the cable with a grapnel before splicing on board.
- Protection methods include physical shielding (e.g., metal sheathing), providing maps to fishermen, and governmental efforts to secure data transmission.
