D.McAfee et al.(2022) showed that #oyster #larvae react to the #soundscape of a healthy #reef via #statocysts in front of their bodies, thus finding their adult conspecifics for #reefformation. Reef formation can be artificially #stimulated via artificial #soundwaves.

  6. COUNT(*) vs COUNT(column) Are DIFFERENT?!

    The #components needed to give a device the properties of a #computer have become increasingly smaller. M. M. Lassiter et al. (2025) designed the #smallest #microrobot to date, measuring just 200 by 300 μm wide and 50 μm thick. It can #aggregate, #communicate, #sense, and #move via #electricalfields inside #fluids. There are interesting applied options for using such a robot in e.g. medical contexts.

  24. The #firebug #Pyrrhocoris apterus is widespread throughout much of #Palearctic. Adults and the five nymphal stages tend to #aggregate. They are #soildwellers and feed on plant #seeds, occasionally also on insect eggs. Some mite species can be on the bugs, with the #parasitic #mite #Hemipteroseius adleri being particularly specialized for it.

  25. Мой путь к быстрой и понятной архитектуре, или зачем я выбросил агрегаты из DDD?

    Данная статья затрагивает некоторые аспекты при выборе подхода к проектированию предметной области для сложных корпоративных систем. В ней исследуются причины возникновения классических подходов и их анализ, для возможного улучшения. Это моя первая статья на данную тему. В начале хочется сказать, что предложенная концепция не пытается претендовать на роль какой-то панацеи и уж тем более на роль единственно верной, она так же имеет рад своих преимуществ и недостатков. Это скорее попытка переосмыслить опыт, который накопился у меня за несколько лет проектировании корпоративных систем. Материал изложен в виде вопросов и попыток на них ответить.

  28. It's 2024 and still, no easy way to #aggregate your data from multiple #health and #fitness #sensors without relying on 3rd party proprietary solutions.

    Imagine you've been saving your data for years but then your sensor needs to be replaced but the sensor is made by another manufacturer, a new data silo is formed because most companies force you to only use their solution or big tech sync.

  29. Aggregate (geology) (Petrology 💎)

    In the Earth sciences, aggregate has three possible meanings. In mineralogy and petrology, an aggregate is a mass of mineral crystals, mineraloid particles or rock particles. Examples are dolomite, which is an aggregate of crystals of the mineral dolomite, and rock gypsum, an aggregate of crystals of the mineral gypsum. Lapis lazuli is a type o...

  31. Пиррова победа Domain-Driven Design

    TL;DR: DDD неизбежно ведёт к избыточному (на порядки больше минимально необходимого) количеству саг в проекте, которые, в свою очередь, неизбежно ведут к нарушению целостности данных в БД. DDD вполне успешно решает поставленную задачу: дать разработчикам инструменты, которые позволят им справится (корректно реализовать и поддерживать) со сложной предметной областью. Но эта победа оказалась пирровой: инструменты, обеспечивающие корректность данных в памяти , оказались неспособны гарантировать корректность данных в БД . А что толку от изначально корректных данных в памяти, если со временем (после их сохранения в БД и последующего чтения) они перестают быть корректными? По сути, у DDD есть фатальный недостаток: DDD неизбежно приводит к нарушению целостности данных (инварианта бизнес-логики) в БД .

    2. Automate the collection of data from multiple sources (some basic ETL)
    3. Reformat the data into a standardized format like [#OpenmHealth](openmhealth.org/documentation/)
