StaticECS — Bitmap Entity Component System
За десятилетия существования ECS сложились два фундаментальных способа хранить компоненты: архетипы (Unity DOTS, Flecs, Bevy) и sparse sets (EnTT, LeoECS). Каждый из них несёт структурные ограничения, которые не устраняются оптимизацией реализации — они вытекают из самой модели данных. StaticEcs — третья модель. Она основана на инвертированном иерархическом битовом индексе : не сущности хранят маски своих компонентов, а компоненты хранят битовые карты сущностей. Фильтрация запроса — это побитовое AND, обрабатывающее 64 сущности за одну инструкцию CPU. Добавление или удаление компонента меняет один бит и не перемещает никаких данных. В статье разбираю, как устроена эта архитектура, чем она отличается от архетипов и sparse sets, и что даёт на практике.

New #review today: "#Evolución is a Chilean band that has been around since the early 80s, though their recorded output is sparse; Secretos is a live album recorded in 2006-2007 and released in 2021. While I can’t fault the players for their technique, the music is instrumental fusion-oriented rock somewhat on the generic side." #ExposeOnline #MylodonRecords #JazzRock #ProgressiveRock #fusion http://expose.org/index.php/articles/display/evolucion-secretos-2.html

Natalie Jane Hill: Hopeful Woman
There's a beautiful vagueness in the cover art to Hill's latest album. It matches the music perfectly, a sparse folk not overly concerned with the details. You get all you need from her songs, voice, and the strum of her acoustic guitar. The other stuff - well-placed bits of pedal steel, flute, drums, harmonies - make the lovely even lovelier, but from a perfect distance on the periphery. It's all pretty great and a few tracks reach that next listen-to-that-again level of songwriting. Enjoy!

Pedalata Resistente - Chieri
Piazza Don Bosco, Chieri, domenica 19 aprile alle ore 15:30 CEST
Pedalata resistente
Pedalara tra le lapidi sparse per chieri
Ritrovo in Stazione, ore 15.30
Andremo a riscoprire le storie dei partigiani che hanno liberato la nostrà città per capire e conoscere le nostre radici politiche.
Giro in bici adatto a tutt3, se non hai una bici contattaci!

Wet cobblestones mirror the glow of paper lanterns in Kobayashi Kiyochika’s *Kagurazaka Street after a Night Rain*. The sparse figures and muted reflections suggest quiet resilience in a city still stirring from the storm.
How does the balance of light and shadow shape the mood of this nocturnal scene?

Arcee AI released Trinity-Large-Thinking, a 400B parameter open-source reasoning model that scores within 2 points of Claude Opus on PinchBench while costing 96% less at $0.90 per million tokens. Uses sparse architecture activating only 13B parameters per token. Trained for $20M by 30-person team. #OpenSource #AI #ReasoningModels

#FieldworkFriday: Sometimes the smallest finds tell the biggest stories. 🏺
Douglass et al. explore how sparse artifact scatters can reveal long-term patterns of land use. Using cases from Australia and the US, they show why documenting every the find is key.

This has to be my favorite episode of "Fall of Civilizations" thus far. The way Paul Cooper tells this story, the sheer amount of detail in an already very sparse part of history is just astounding. I'm really impressed and highly recommend this to people interested in ancient history.
The massacre at the end and what led to it made me feel quite sad about Carthage. We often forget that civilizations are temporary. So much has been repeated over time when one looks at history. I think nothing that is happening today seems that much different from before.

Behold, a GitHub snapshot where #AI attempts to sprinkle "intelligence" like fairy dust 🌟 on code creation, while developers feverishly click through menus hoping to automate away their existential dread 🤖. Meanwhile, "Memory Sparse Attention" pretends to be the savior of our digital attention spans, though it's more like a caffeine-free energy drink for your neurons ☕️.

Here is the *third* manuscript coming out of the "Topics in Ramsey theory" online-only problem-solving session (https://sparse-graphs.mimuw.edu.pl/doku.php?id=sessions:2025sessions:2025session1) of the Sparse (Graphs) Coalition, which took place less than a year ago.
It is still surprising to realise what one can make of such events, if they are set up well.

Hello Vivaldi Social!
Why do humans cling to time?
Because it's always sparse.I like to craft on my #homelab and #automate as much as possible. Curious about learning new stuff about #technology, #psychology and #philosophy. When not hitting the keyboard I am running around #nature and develop my #photography skills. To unwind I like to play #videogames and #boardgames or #meditate.
