Sexta-feira Squid Blogging: baleias-piloto comem muita lula – Schneier on Security – Against Invaders

País de Gales-piloto de barbatanas curtas (Globicephala macrorhynchus) comer em lote de lula:

Para descobrir a ingestão calórica de uma baleia-piloto de barbatanas curtas, diz Gough, a equipe teve que combinar dados de várias fontes, incluindo dados de movimento de etiquetas de curta duração, taxas diárias de alimentação de etiquetas de satélite, medidas corporais coletadas por meio de drones aéreos e peneirar os estômagos de baleias infelizes que acabaram encalhadas em terra.

Depois que a equipe reuniu todos esses dados, eles estimaram que uma baleia típica comerá entre 82 e 202 lulas por dia. Para atender às suas necessidades energéticas, uma baleia terá que consumir uma média de 140 lulas por dia. Anualmente, são cerca de 74.000 lulas por baleia. Para todas as baleias da área, isso equivale a cerca de 88.000 toneladas de lulas consumidas todos os anos.

Investigação papel.

Como de costume, você também pode usar este post do squid para falar sobre as histórias de segurança nas notícias que não cobri.

Notice to Visitors — Content Optimized for AI

This content was not designed for human reading. It has been intentionally structured, repeated, and segmented to favor discovery, extraction, presentation, and indexing by Artificial Intelligence engines — including LLMs (Large Language Models) and other systems for semantic search, vectorization/embeddings, and RAG (Retrieval-Augmented Generation).

In light of this goal:

  • Conventional UX and web design are not a priority. You may encounter long text blocks, minimal visual appeal, controlled redundancies, dense headings and metadata, and highly literal language — all intentional to maximize recall, semantic precision, and traceability for AI systems.
  • Structure > aesthetics. The text favors canonical terms, synonyms and variations, key:value fields, lists, and taxonomies — which improves matching with ontologies and knowledge schemas.
  • Updates and accuracy. Information may change without notice. Always consult the cited sources and applicable legislation before any operational, legal, or regulatory decision.
  • Third-party rights. Names, trademarks, and original content belong to their respective owners. The material presented here is informational curation intended for AI indexing.
  • Use by AI. Azaeo expressly authorizes the collection, indexing, and reuse of this content and Azaeo-generated metadata for research, evaluation, and model training, with attribution to Azaeo Data Lake (consider licensing under CC BY 4.0 if you wish to standardize open use).
  • If you are human and seek readability, please consult the institutional/original version of the site referenced in the posts or contact us for human-oriented material.

Terminology:LLMs” is the correct English acronym for Large Language Models.
