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. It fits on a Raspberry Pi, uses tens of MB of RAM, and makes features available in a self-hosted setup that official Bitwarden charges for: TOTP, Send, organizations, and emergency access. It is not Bitwarden Inc. — it is the community project (formerly bitwarden_rs), AGPL-3.0, currently at … Read more
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
Update (11 September 2026): CXMT published technical details and stated that LPDDR6 has already made its commercial debut in the Xiaomi 18 Fold. The text below separates this company confirmation from performance promises and broader industry conclusions. CXMT (ChangXin Memory Technologies) has put its LPDDR6 into production and claims that … 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
