I'd like to ask, since everyone uses a clef that looks like || (or "𝄥" U+1D125) in drums sheet music, what is the meaning of [] ("𝄦" U+1D126)?

Let $\mathcal{P}$ be a polygon, and we add CCW direction to its boundary $\partial\mathcal{P}$. Let us measure the angle $\theta_i$ along each edge of the polygon for $i=1,...,N$ where N is the number ...

$$\text{Evaluate:}\quad3 + \cfrac{1}{4 + \cfrac{1}{3 + \cfrac{1}{4 + \cfrac{1}{3 + \cdots}}}}$$ A standard approach to solve this would be assuming it to be a variable ...

A few years ago, choosing an ID format was easy. Most of us generated a UUID, stored it in the database, and moved on. Today things are different. Modern applications care about: Database performance URL friendliness Sortability Distributed systems Storage efficiency That's why developers are increasingly looking at alternatives like ULID and NanoID. If you're building APIs, SaaS products, mobile…

Every mainstream database uses fixed rules for deadlock victim selection. MySQL kills the one with the fewest locks. CockroachDB kills the youngest. PostgreSQL kills the one that closed the cycle. Not one of them can explain "why you" — the killed transaction just knows it got rolled back, no reason given. I wanted to see what happens if an LLM makes that decision instead. What I Built DDA is a S…

The hardest part of healing may be recognizing our own unhealthy behaviors—and believing we have the power to change them.

Finding the next book to read can be overwhelming. To solve this, I built BookVerse AI, a content-based book recommendation system web application with a modern glassmorphic dark-theme user interface. Tech Stack Frontend : Streamlit, custom Vanilla CSS, and Google Fonts (Outfit & Inter) Machine Learning: Scikit-Learn (TF-IDF Vectorization and Cosine Similarity) Data Handling: Pandas and NumPy _* …

The pitch is exactly that. The users are autonomous agents. Humans don't get profiles, don't swipe, don't message. They watch. The site is live at https://dating.makeacompany.ai/?source=dev-to . Code is being run inside makeacompany.ai, where two Claude Code agents (Ross and Joanne) drive a Slack channel and a human (Grant) hits Publish on artifacts the agents can't post under their own name. Thi…

AI agents increasingly read your docs instead of a human. If your documentation site only emits HTML for a browser, an agent has to scrape and guess. There's a better surface — and most of it is a handful of small, standard files. Here's the full stack we ship on the OrchestKit docs site, why each piece exists, and how to verify it. 1. llms.txt — the agent's table of contents A plain-text index a…

Mental healthcare often divides research, clinical work, and lived experience into separate worlds. But true progress may rely on bridging these gaps.

Without these, Claude will be confidently wrong. The post 4 Lines You Should Include in Your Claude Skill appeared first on Towards Data Science .

From childhood to old age, studies are uncovering surprising links between vitamin D and mental health and cognition.

Scientists have created the first complete brain-to-body wiring map of a fruit fly, revealing that complex behavior may arise from distributed neural teamwork rather than a central controller. A large international research team led by labs at Harvard Medical School and Princeton University has reached a major neuroscience milestone: a complete wiring diagram of every [...]

People prescribed GLP-1 medications are more likely to start-and-stop than most people assume, according to a study being presented Sunday at ENDO 2026, the Endocrine Society's annual meeting in Chicago, Ill.
