Elevators aren’t just “machines that come when called.” Behind the scenes, elevator banks continuously schedule car stops and assign passengers to cars using policies that balance wait time, congestion, and traffic patterns. Understanding SCAN/LOOK-style routing and dispatching strategies explains why mornings feel worse and why newer systems can sometimes make waits longer.
Publishing is entering a phase where AI-written text is cheap and detection is unreliable. The durable solution is provenance-by-design: hashing and signing build artifacts so authors and publishers can verify what produced the final manuscript.
AI session “transcripts” often look portable, but providers increasingly keep operational state server-side or seal it with provider-bound encryption. That turns user archives into pointers, with missing evidence and limited replay. This post explains session portability tests and the design patterns that keep sessions truly exportable.
AI chat interfaces popularized streaming text and shimmering placeholders, and those behaviors became recognizable UI aesthetics. Under the polish are concrete technical patterns: HTTP streaming, incremental rendering, and skeleton loading that communicates uncertain wait states.
GPT‑5.6 Luna and Terra are cheaper, and GPT‑5.6 Sol adds Fast mode for lower latency. This post breaks down how token pricing, prompt caching, and inference/agent efficiency combine for better AI ROI in real workloads.
gpiozero’s source/values model treats GPIO devices as value stream producers and consumers, where `.source` wires an output to an iterator of changing values. gpiozero-flow turns those same relationships into a drag-and-drop canvas, then uses a WebSocket agent to rewire live gpiozero devices and stream real hardware state back.
EU officials have raised concerns about foreign interference in European elections, including via online influence and cybersecurity risks. The technical story isn’t one hack—it’s how political ads, information campaigns (FIMI), and election infrastructure can be attacked together, and how EU coordination and regulations aim to blunt those pathways.
A new preprint argues that many AI unicorn startups contribute almost nothing to the formal scientific record. Over half reportedly produce no citable paper or preprint, reducing reproducibility and making safety evaluation harder—especially when model details stay opaque.
TurboFieldfare runs Gemma 4 26B-A4B on Apple Silicon with ~2GB RAM by keeping core weights + an FP16 KV cache resident and streaming only the routed MoE experts from SSD. This post explains the memory pieces (MoE routing, KV cache, quantization) and walks through building, installing, and tuning the runtime.
KOReader is an open-source e‑ink eBook reader that makes PDFs feel workable: reflow, OCR-assisted text extraction, zoom modes, and smarter navigation. It also supports customization through Lua-based plugins.
