Why Google added BERT to search in 2019, how MLM training really works (15% mask, 80/10/10, WordPiece), and where encoder-only models still beat LLMs — rerank, classification, and OCR correction.
Tested on M1 Max: Floyd-Steinberg halftone + BLE pacing + a vendor-specific density command `1D 49 F0 nn` to print sharp photos on the Sugar YMP-01 thermal mini printer from Python.
Tested on M1 Max: switching a Python BLE client to RFCOMM (SPP Ch.2) cuts transfer from ~60s to 5.38s for a 140KB JPEG. Covers PyObjC quirks, macOS Bluetooth entitlement, and an isolation experiment confirming olie.xdev's 'possibly not required' steps.
Tested Orbis in Docker: psf/requests (35 modules) makes a clean 3D graph, expressjs/express (98 modules) collapses into one giant sphere. Notes on what tree-sitter actually captures for code-review prep.
uv 0.9.21 as the entry for small Claude SDK Python experiments: uv init, uv add, uv run, uv.lock keep agent projects reproducible across machines and Codex/Claude Code sessions. Operational notes, not a benchmark of the DEV article's uv 0.11.11.
Steps to set up Apache Airflow 3.2.0 with a PostgreSQL metadata database, run your first DAG, and configuration notes for moving beyond standalone mode.
Hands-on log of building the DEV article's PDF RAG on M1 Max 64GB, extending it with images via CLIP, and pushing through Japanese with bge-m3 + Qwen3.6 35B. Documents the modality gap, the dual inference server crash, and LLM-jp 4-8B's empty chat template silently dropping the system role.
Notes on a DEV Community article that wires up FastAPI as an OpenAI-compatible RAG API layer with llama.cpp, Chroma, and Open WebUI, plus where the architecture fits and what to watch for.
An experiment log investigating USB/WiFi/BLE connection specs of the Nikon COOLPIX A1000 and attempting PC connection via OSS tools. PTP/IP protocol analysis and gphoto2 testing results.
A paper claims that a single binary operator eml(x, y) = exp(x) - ln(y) combined with the constant 1 can express all elementary functions — arithmetic, trig, logarithms, even pi. I read the paper and tested it in 5 languages.
