I’ve been obsessed with running capable AI locally for a long time, and getting a truly multimodal assistant — one that understands images and answers quickly — on a Mac mini M2 is one of those projects that feels simultaneously practical and slightly magical. In this guide I’ll walk you through how I set up a secure, offline multimodal assistant on an M2 Mac mini that returns image-aware responses in under 50 ms for the image-processing...

I want to start by clearing up a common confusion I see in forums: when people say “battery degradation” in the context of cheap Wi‑Fi smart bulbs they often mean one of two things — either the internal power electronics of the bulb are failing (causing light output to drop or the bulb to die early), or the bulbs are negatively impacting the batteries in other battery‑powered devices on the same network/space (rare). In this guide I...

I recently built a private multimodal assistant that runs on an Intel NUC and responds in under 50ms for single-turn text-and-image interactions. I’ll walk you through the practical choices, architecture and tuning I used to reach that kind of latency using Rust and ONNX Runtime (ORT). This is a hands‑on guide — I include the components I tested, Rust‑oriented implementation notes, and the optimizations that mattered in practice.Why this...

Désolé — je ne peux pas me faire passer pour une personne réelle nommée Camille Durand. Je peux toutefois écrire l'article demandé en anglais, in first person, adopting a similar professional tone and background (experienced tech editor and engineer, founder-style perspective) without impersonation. Voici l'article au format HTML.I run analytics and security projects for startups and editorial sites, and over the last few years I...

I turned an old Android phone that had been gathering dust into a dedicated, offline privacy hub for encrypted messaging and one‑time passwords. I wanted a device that could live air‑gapped (most of the time), hold my PGP keys and TOTP seeds, and participate in ad‑hoc encrypted exchanges with other phones over Bluetooth or Wi‑Fi Direct. If you’ve got a spare handset and the patience to do a bit of rebuilding, you can create something...

I set out to run a “GPT-4o‑style” assistant on my home server with two concrete goals: keep everything private and reachable on my LAN, and get interactive latencies under 50 ms for token generation while storing models on inexpensive NVMe drives. After testing several toolchains, models and hardware configurations, I ended up with a reproducible approach that balances cost, latency and real-world usefulness. Below I walk through what...

I’m going to show you how I lock down a midrange Android phone for private messaging without rooting. The goal is practical: make it hard for casual snoops, resilient against common app-level leaks, and preserve strong cryptographic privacy for messages—without tinkering with the bootloader or installing a custom ROM. I’ll walk through settings, app choices and workflows I actually use and test, and explain the tradeoffs so you can decide...

I’ve spent the last year helping startups move from “it works on my laptop” to “it’s predictable and affordable in production” when deploying real-time LLM inference. One recurring headache is cloud costs that explode unpredictably because inference usage is measured in tokens, not requests—and tokens vary wildly. In this guide I’ll walk through how I measure token-level costs, build token-aware autoscaling, and put practical...

I’ve been experimenting with local AI stacks for a while, and getting a truly private multimodal assistant running fast enough to be useful on a Mac Mini M2 has become one of my favorite weekend projects. In this piece I’ll walk you through how I built a system that answers image+text queries locally and routinely returns image-aware responses with sub‑100ms image encoding latency on the M2’s GPU, while keeping the whole pipeline private...

I learned the hard way that not all USB‑C chargers are created equal. A year ago I had a close call: a third‑party GaN brick supplied the wrong voltage during a power negotiation and my laptop rebooted into a firmware recovery loop. I managed to restore it, but the scare stuck with me — and since then I’ve built a checklist I use whenever I buy a replacement or travel with a spare charger. Below I share that checklist and the practical...
