Run DeepSeek R1 Locally: Reasoning Models on Consumer Hardware

Run DeepSeek R1 Locally: Reasoning Models on Consumer Hardware

You can run DeepSeek R1 ’s distilled reasoning models on an RTX 5080 with 16 GB of VRAM. Use Ollama or llama.cpp with 4-bit quantization. The 14B distilled variant (Q4_K_M) fits in about 10 GB of VRAM. It shows visible <think> reasoning traces that rival cloud quality on math, coding, and logic. The full 671B model needs multi-GPU rigs, but the distilled models give you 80-90% of the quality for far less hardware.

Custom Linter Rules: JavaScript, Python, Go ASTs

Custom Linter Rules: JavaScript, Python, Go ASTs

You can catch domain-specific anti-patterns that ESLint , Ruff , or golangci-lint miss by writing custom linter rules that parse your code into an Abstract Syntax Tree (AST), walk the tree to match specific node patterns, and report violations with auto-fix suggestions. The process is the same regardless of language: parse source into a tree, define the pattern you want to catch, walk the tree to find matches, and emit diagnostics. In JavaScript/TypeScript, this means writing an ESLint plugin with a visitor-pattern rule. In Python, you write a flake8 plugin using the ast module or a Ruff plugin in Rust. In Go, you use the go/ast and go/analysis packages.

Promptfoo: Catch LLM Regressions Before Production

Promptfoo: Catch LLM Regressions Before Production

Promptfoo is an open-source CLI tool that runs your test cases against one or more LLM providers at once. You write a YAML file with prompts, test cases, and checks, then run promptfoo eval to get a report with pass/fail rates, regressions, and side-by-side comparisons. It scores results three ways: simple text checks, LLM-as-judge grading, or your own scoring code. The point is to catch prompt regressions, broken model upgrades, and quality drops before users see them.

Python Markdown Blog: 100 Lines of Code

Python Markdown Blog: 100 Lines of Code

You can build a working static site generator in about 100 lines of Python. The result reads Markdown files from a content directory, parses their YAML front matter, converts the Markdown to HTML, wraps everything in Jinja2 templates, and writes the output to a public/ folder ready to be served by any web server. It is the same fundamental pipeline that powers tools like Hugo , Jekyll , and Eleventy - just stripped down to the essentials so you can see exactly how the pieces fit together.

RAG vs. Long Context: Choosing the Best Approach for Your LLM

RAG vs. Long Context: Choosing the Best Approach for Your LLM

RAG and long context windows are not competing replacements. They are different tools built for different problems. If you are trying to choose between them, the short answer is: it depends on the size and nature of your data, your latency and cost constraints, and how much infrastructure complexity you are willing to maintain. The longer answer involves understanding what each approach actually does, where each one breaks down, and what teams running production LLM systems are doing in 2026 - which is usually some combination of both.

Veepeak vs OBDLink: BLE OBD-II for Home Assistant

Veepeak vs OBDLink: BLE OBD-II for Home Assistant

You can stream live vehicle diagnostics and GPS location to Home Assistant by pairing a Bluetooth Low Energy OBD-II adapter with an ESPHome -based BLE proxy or a dedicated Android device running Torque Pro . This setup feeds real-time fuel economy, engine codes, coolant temperature, and GPS coordinates into Home Assistant entities, enabling geo-fenced automations like opening your garage door on arrival or logging trip fuel costs - all without any cloud dependency.

Most modern vehicles (1996+ in the US, 2001+ in Europe) expose a standard OBD-II diagnostic port, usually located under the dashboard near the steering column. That port speaks well-documented protocols and can report dozens of parameters from the engine control unit (ECU). The hard part is getting that data off the wire, through Bluetooth, and into Home Assistant in a way that is reliable enough to actually automate around. Below I cover hardware selection, the ESPHome BLE bridge, GPS tracking, dashboards, and the troubleshooting you will inevitably need.
