I like fast cars. 🏎️ Driving… watching GT and F1… learning about engines and efficiency, drag coefficients and gear ratios, tire compounds and braking points. The mechanical and precision aspects of racing are incredibly appealing to the mathematical part of my mind. A small input to the steering wheel or…
Every few years, I tweak RK.MD’s design to refresh my content and to leverage the latest technologies at that time. My goals for 2026 are to address a few lingering headaches built up over the years: The goal was simple: make this as lean, consistent, and content-centered as possible by…
Over the last month, I’ve been slowly refining a workflow that lets me run a private large language model (LLM) on my NVIDIA DGX Spark. I wanted an inference model that lives entirely on my own hardware, never leaves my network, and feels responsive enough for writing, coding, and day-to-day…
Rather than using a separate plugin or paid service, I used macOS’s Automator application to create a folder action that converts popular image and video file types to AVIF and WebM, respectively. This way, regardless of the media format, I can drop it into a predetermined folder on my Mac…
The Batcave (my office) has had an eyesore of a cabinet which housed my original network attached storage (NAS), uninterrupted power supply (UPS), and some accessories. Because of poor ventilation, I had used a saw to cut out not-so-perfect circles in the rear and mounted some 140 mm fans as…
It’s been a few years since I last did a “What’s in my work bag?” post, so here’s an update! Check out my prior posts from 2021, 2020, 2019, 2017, and 2016. Depending on what I’m doing on any given day (reading journal articles, programming at a coffee shop, creating…
One of the many tech advantages of having a Tesla is utilizing the vehicle’s external cameras to detect and record activity while driving and parked (“Sentry Mode”). This feature isn’t something for the Taycan, so I installed an aftermarket dash cam and went with the FITCAMX 4K Dash Cam. This…
While I’ve loved my Model S Plaid for its performance and futuristic tech, I’ve always wanted to add a true “driver’s car” to the stable. One with a more analog soul – something more planted, precise, and engaging that’s not just about sheer acceleration. For years, I’ve had my eye on Porsche…
I set up a self-hosted large language model (LLM) workflow using Open WebUI and Ollama on my local machines a week ago. By self-hosting, I don’t need API keys or cloud dependency… just pure local inference! With Open WebUI serving as a sleek front-end and Ollama managing the back-end LLM runtime, it has been quite enjoyable to…
This is a walkthrough for how I use a personal domain name hosted at Cloudflare to direct traffic via Tailscale to a sidecar NGINX Proxy Manager (NPM) Docker container on my Synology NAS which, in turn, I use to obtain SSL certificates and reverse proxy requests to various Docker containers.…
