# fosk

> fosk.it is the personal workbench of Sandro Cavalieri Foschini, known online as fosk. He works in networking and cybersecurity, and this site collects what he builds after hours, out of curiosity or to solve a problem of his own. His formal site, with résumé and work, is https://sandro.cavalierifoschini.it/en/

The site is a single page in English. It has no cookies and no tracking.

## Projects

- [gputaskman GUI](https://fosk.it/#banco): a graphical GPU monitor for Windows, Linux and macOS, built on a fork of gputaskman. It breaks down VRAM in real time across LLMs, AI processes, games and browsers, next to utilization, temperature, power and clocks. For local language models it also shows weights, KV cache, parameters and the loaded file. Version 0.3.0, in development, free.
- [gputaskman GUI downloads](https://github.com/fosk/gputaskman/releases/tag/gui-v0.3.0): builds for Windows x64 and ARM64, Linux x64 and ARM64, macOS Apple Silicon.
- [gputaskman source code](https://github.com/fosk/gputaskman)
- [iperf3 speed test](https://fosk.it/#banco): an Android and iOS app for measuring real bandwidth against public iperf3 servers, with no ads and no tracking. It is in design and does not exist yet. The images on the site are concept mockups.

## Tools

- [Radio link budget calculator](https://fosk.it/#tratta): a free-space link budget for point-to-point radio links at 2.4, 5.4, 13, 18, 23, 60 and 80 GHz. Given distance, transmit power, antenna gain and receiver sensitivity, it computes path loss (20·log10(km) + 20·log10(MHz) + 32.44), received level, fade margin and the Fresnel radius at mid-path. It ignores rain, oxygen absorption at 60 GHz, obstructions and cable losses.

## Interests

- Local AI: running language models on his own GPU.
- Network security: how networks are defended and put to the test.
- Home automation: treating the home as a small network to design, measure and automate.
