As you might already know, I’ve just placed three Arduino MEGAs around my new house and I’m using them to –among other things– turn on/off the lights of the whole house. I still have to “enter” the new house so… I’m currently “configuring” the “light-switching” system (associating LIGHTs with related Push-Buttons). After several”upgrades” of the … [Read more…]

To be short: for one of my customers, I setup … [Read more…]

The process list is very long, and most of them are OPTIONS * HTTP/1.0, which I want to filter away. Is there any tweak, option or flag to hide those OPTIONS … [Read more…]

Let’s start from this: if you’re a Linux power-user & you’re owning an Android MTK-based device & you’re wondering how to get root (…and what kind of benefits you’ll have, concretely, being root), this page is for you. I’m the —happy, indeed— owner of two so-called Android china-devices: an UMI C1 smartphone and a Cube … [Read more…]
