VRAM determines the model. Dense Qwen 27B–32B, quantized Llama 70B, Mixtral 8×7B — these require 32 to 64 GB, not the 24 GB of a 4090. Engineer Donato Capitella, with Bargain Hardware, built a refurbished Supermicro with four data center GPUs (64 GB total) for around £2,000 and benchmarked V100, P100 … Read more
How many calculations does a graphics card perform per second to draw a Cyberpunk frame or train a network? Branch Education took apart an RTX 3090 — literally — and reconstructed the GA102 die in 3D. This article follows the video How do Graphics Cards Work? Exploring GPU Architecture. The generation … Read more
Programming is: data + rules → answer. Pricing a house, recognizing a face, understanding Portuguese — manually written rules cannot handle it all. Machine Learning reverses the equation: data + example answers → the model (the rules). This article follows KodeKloud’s course How Machine Learning Works, End to End: from spreadsheets to ChatGPT, the cycle … Read more
Jason Dsouza’s Deep Learning Crash Course for Beginners on freeCodeCamp maps the territory: what DL is, how a network learns, the vocabulary (loss, Adam, epoch), and the three architecture families. This article condenses the course. The math underneath — MatMul, GPU — is covered in GPU vs TPU; the … Read more
Recognizing a scribbled 3 in 28×28 pixels is instant for you. Writing an if/else that does the same — a curve here, a stroke there, and what if it is crooked? — is a nightmare. The neural network in But what is a neural network? from 3Blue1Brown (Grant Sanderson) breaks it down: it is not magic, but a function with … Read more
Vaultwarden is a server compatible with the official Bitwarden clients, written in Rust. Updated guide for 1.37.3: Docker Compose with Caddy, stuck registration, native SSO, backup with the built-in command, and safe update.
Behind every ChatGPT token, every Sora frame, and every LLM you run in Ollama, an accelerator performs the same calculation trillions of times: matrix multiplication. The two ways to do this in silicon — GPU (NVIDIA) and TPU (Google) — start from opposing philosophies. This article … Read more
Moving a VM from VirtualBox or VMware to XCP-ng (or XenServer) usually becomes a ritual: export OVA, convert the disk by hand, and wrestle with xe. ova2xva is a Go CLI (MIT) that handles the trip in both directions in a single binary — converting an OVA or standalone disk … Read more
If you run AI models locally with llama.cpp / llama-server, you know the pain: download GGUF by hand, edit the configuration, restart the service, and hope the model starts. llama-model solves this — a Go CLI, one static binary, that manages your model collection and the llama-server service without needing the daemon from … Read more
On August 25, 2026, Linux turned 35. In 1991, a 21-year-old Finnish student named Linus Torvalds posted a message to comp.os.minix that would become history: Hello to everybody out there using minix — I am making a (free) operating system (just a hobby, won’t be big and professional … Read more
