It’s not easy! At least it wasn’t for me on my latest debian buster. Unless you grab a lot of different pieces of information and make it work of course. Let me share the endeavor. Building the driver. After a lot of attempts with outdated source code I managed to get my adapter blinking ( Read More …
Getting broadcom chipsets working on Linux (wifi/bluetooth, separate/combined) is a pain. Each time again as they are non-free as by default not included. You got it working once, but don’t remember how it went if you try a new distro. Tired of going on a google session everytime again, I decided to write it down. Read More …
I’m not at all affiliated with Joplin as I just stumbled upon this beautiful piece of software a while ago. In a nutshell it works on the 3 major platforms, it synchronises with the major cloud providers and even with owncloud. And last but not least it works from the command line! For a professional Read More …
I graduated long time ago as electronics engineer but eventually ended up in software engineering. Recently I wanted to start playing again a bit with electronics and decided to build some mundane projects just to try to understand popular components. In this post I show the popular Led Chaser, implemented using a 555 timer and 4017 Read More …

To achieve blue/green deployment on AWS, you put all your resources that can die and revive (think auto scaling groups, malicious terminations, but also whole Read More …
In a previous post I talked about the pairing issues on an Ubuntu machine with a vanilla (otherwise decent) Bluetooth USB adapter. Further down the road, doing nothing really special than using the QC35 on my smartphone, laptop and (Ubuntu) desktop at home, it seemed to work for, well since my last post about it. Read More …
The latest certbot-auto tool comes with a new feature (or I must have missed it 3 months ago) that spawns up a temporary web server on port 443. This is a huge improvement IMHO as it avoids the permissions hassle you can have on a security-hardened web server installation (be it Apache, IIS, Nginx, …). The Read More …
I recently bought a cheap but working Bluetooth usb dongle (Konig CSBLUEKEY200) for a refurbished desktop running Ubuntu 16.04. Connecting to my Nexus 6 Android phone worked seamlessly, so confident about it I hurried to connect my Bose Quietcomfort 35 headphone. I initially got it detected but pairing was a no go, whatever I Read More …
