October 2025

October’s tech picks: updates to my Timy app (timesheet + planner), ideas on data centers in space, fractals in JavaScript, Three.js for 3D web, Edge AI with Microsoft’s course, and Balena WiFi Connect for easy Raspberry Pi setup.

I’ve added some features to my Timy application, which has born as a Timesheet application for a client. With time I’ve added a Planning component and a To-dos list manager. I use it daily to organise my jobs and keep tracks of time spent on projects and things to do. Maybe it could become an app sold in Sass mode, but it takes time, as usual. Maybe one day.

Some companies are planning to store cloud servers on satellites on space, to save energy costs (energy is freely available from sun) and solve cooling problems (out in the space it’s really cold). It sounds really incredible but could be an environmental choose.

Fractals are never-ending patterns created by repeating mathematical equations, which, on any scale, on any level of zoom, look roughly the same. I’ve always been fascinated by these mathematical figures, Lautaro Lobo describes how to draw some fractals with JavaScript.

I’m really afraid of Gaza situation, and I’m afraid that Europe did quite nothing about it, except the Sumud Flottilla movement from common people. So I was a bit happy when I’ve read that Microsoft blocked some servers where Israel stores data about Palestinians. Don’t know if this thing last long.

Looking around to find some libraries to use 3D graphics in the browser, I discovered Three.js. There are also free courses which could help to make a quick start into WebGL and 3D. Three.js should make it simple to create a configurator online for a specific product.

Edge AI refers to running AI algorithms and language models locally on hardware, close to where data is generated without relying on cloud resources for inference. It reduces latency, enhances privacy, and enables real-time decision-making. Here is a course online by Microsoft to start the journey in AI and EdgeAI.

If you build a product that needs internet access, you probably need to add an easy way (for non dev users) to give SSID and password to the device. To achieve the result, usually your device should start as an access point, so from a smartphone you can connect to it and input credentials in a web page, normally called “captive portal”. I often did this interfaces and the whole implementation on ESP devices, now that I’ve started some projects on Raspberry pi only at the end I’ve found that obviously there are similar techniques also on Rasp devices. One of this is called Balena Wifi Connect.

With Sintesi Labs Design GmbH, I took part in setting up the exhibition event for the Long Night of Museums at the Max Planck Institute in Munich!
The event presented the Institute’s research on animals, studied through data collected via GPS tags, drones, sensors, and cameras.
All this data together forms an astonishing Internet of Animals. I built some interactive installations featuring buttons, levers, an accelerometer, and a camera — all powered by Raspberry Pi and Arduino. During the event, I had a great time chatting with the biologists and scientists from the MPI.

Let’s take a moment of silence in solidarity with the Amazon Web Services sysadmins who had a big trouble day with DNS due to a race condition that brought down half the internet: how an error can growth up. :-)
