Last year I upgraded my solar water panels with some temperature probes, and I scattered NodeMCU in my house (with some DHT22 and DHT11 sensors). At the time I had an old PC that was acting as a server: IoT devices were sending readings to RabbitMQ instance on that server, with a shell script that was bridging between MQTT and RRDTool database.

Of course, for me that was perfect. But I when I tried to share these tools with my family, quickly became clear that I had to make a nice interface. I ended up by sending the chart by Telegram with a bot.

Then, during last month, the old server died. I moved some things to the cloud, and some other things were archived. After some free-time during cleanup (I had two 1TB disks to cleanup...) I landed into Grafana home page. And I decided to give it a try.

Aka: install a safe-mode-access.

I was programming my RasPI 3 to be a Wi-Fi AP. I don't have an HDMI monitor, only an HDMI converter and I'm not happy to use it. So, I was trying to setup my RPI by SSH. Of course, I was locked out by a wrong command in a script.

La "superficie d'attacco" è l'insieme dei possibili punti di un software/sistema/infrastruttura che sono più o meno accessibili da un eventuale attaccante. E' fondamentale quindi conoscere e gestire la superficie d'attacco della nostra infrastruttura informatica.

Ieri, un torrido 10 di Agosto, mi sono unito a Salvatore Antoci in un lavoretto di manutenzione "ordinaria": la riparazione di una panchina (qui le foto di prima e dopo). Ovviamente non facciamo parte della "squadra di manutentori del Comune".
