Bookseller tracking and unsealed court records uncover Anthropic's covert "Project Panama," an initiative that disbinds and scans print books with industrial guillotines for AI training. Title analyses reveal the company targets obscure, low-circulation academic nonfiction from recent decades rather than rare antiquarian volumes. In the excerpted reporting, a federal judge affirms that destructively digitizing legally purchased books constitutes fair use.

God Help Us, Let’s Try To Learn About Mechanistic Interpretability Techniques

With early hopes for clean feature maps now collapsed, reverse-engineering language models relies on pragmatic heuristics. Linear probes detect internal states—such as Anthropic discovering Claude recognizes test environments 8 to 17 percent of the time—yet cause collateral damage when suppressing concepts that networks easily route around. The guide examines these evasion dynamics before outlining how sparse autoencoders unsmush dense activation matrices. (Excerpt.)

Pairing cognitive walkthroughs with laboratory user tests, researchers demonstrate that standard graphical interface conventions fail to make public-key cryptography usable for ordinary email. When given ninety minutes to sign and encrypt a message, a majority of novice participants fail to complete the task successfully. The findings show that computer security requires domain-specific interface standards to handle abstract policies and irreversible configuration errors.

Standard PostgreSQL job systems use FOR UPDATE SKIP LOCKED for worker concurrency, but they ignore downstream provider rate limits and mishandle HTTP 429 backoff. Benchmarking notifyd demonstrates that batching claims, context lookups, and finalization scales throughput from 516 to 3,537 deliveries per second on an eight-vCPU host. The single binary operates entirely within 23 megabytes of resident memory.

Matched interests: ConcurrencyDistributed SystemsSystems Programming

To keep blocking mutexes compact while preventing unbounded priority inversion, kernels decouple waiter bookkeeping from synchronization primitives by donating per-thread tracking structures on demand. Hashing a lock's address locates these detached queues to resolve multi-hop dependency chains without wasting memory on uncontended locks. Though reader-writer locks complicate the single-inheritor model, the mechanism endures across FreeBSD, macOS, and WebKit's ParkingLot.

Matched interests: PostgreSQLMemory AllocatorsDatabase Internals

PostgreSQL’s default 64MB maintenance_work_mem quietly limits parallel index builds to a single worker, as the planner requires at least 32MB per participant. While boosting the allocation paradoxically slows serial B-tree index builds by degrading CPU cache efficiency, it remains vital for memory-bound structures like pgvector HNSW graphs. Setting autovacuum_work_mem separately prevents concurrent background workers from multiplying the global budget.

Function Arguments Are Not Function Colors

Matched interests: Functional ProgrammingAsync ProgrammingConcurrency

Differentiating true function coloring from parameter threading hinges on call-stack encapsulation. While parameters like Go's context.Context can be neutralized early using context.Background(), genuine colors inescapably propagate through every intervening stack frame. This structural rule reveals partial colors like Haskell's STM monad, where rigid type systems prevent intermediate pure functions from encapsulating transactional requirements.

Training representative model architectures against open pretraining corpora from 2019 through 2025 reveals that data improvements drove 3.24 times more compute efficiency gains than model design. Across compute budgets up to 1e19 FLOPs, dataset curation yields a 12-fold efficiency gain compared to 3.7-fold for architectures, with both factors acting largely independently. Architectural progress primarily serves to stabilize large-scale training rather than reduce compute requirements.
