Update / re-flash your Raspberry pi 4 eeprom

Your pi 4 does not boot ?

Or you want to upgrade it to add a new feature ? (No new feature yet 19/07/2019) but some rumors about an update to low the temperature … If you have more information tell me 🙂

So, first, go to Recovery section of the download page and hit the « Download the bootloader » link (I do not add a direct link here, to avoid linking old release)

Next, follow the steps:

2 – extract to an empty fat32 formatted sd card (every old card will do the job)

3 – Plugin into your Raspberry Pi 4 and wait until the led flashes

If it’s not working, you can:

  • download again and extract again the files
  • format again the sd card
  • change the sd card
  • double check the power supply (use the official one, or some of the very good quality vendors, do not use cheap power supplies …

Pidgin for work and facebook messenger

I use pidgin for work to chat with my teammates, but I want to use it to talk sometimes with my wife without connecting to facebook, or facebook messenger nor activate the data/wifi on my phone.

I use to work with my phone offline, only in « phone mode ».

I use Ubuntu 19.04 at the time of this article.

First, I search all the pidgin related stuff with apt:

(sudo) apt-cache search pidgin

In the results I see some interesting things:

pidgin-guifications - Fenêtres surgissantes de messages pour Pidgin
pidgin-privacy-please - Greffon pour une confidentialité accrue dans Pidgin
pidgin-otr - Off-the-Record Messaging plugin for Pidgin
purple-discord - Discord messaging service plugin for libpurple

I install them, I will search for facebook later, discord is for testing, privacy-please and otr is for my paranoia and guifications is to be aware when a colleague of mine talk to me.

(sudo) apt install purple-discord pidgin-otr pidgin-privacy-please pidgin-guifications

Facebook messenger

For this one, we need libpurple-facebook, but ubuntu does not have any package for now.
So we just need to build it 🙂*NIX

(sudo) apt install libglib2.0-dev libjson-glib-dev libjson-glib-1.0-0 libjson-glib-1.0-common libpurple-dev libpurple0 zlib1g-dev gir1.2-json-1.0 libdbus-glib-1-dev libdbus-glib-1-dev-bin

Ok will go for « Compiling -> From A Release Tarball »

Go to
and choose the latest

# I prefer sudo -i and password than sudo every time
sudo -i
tar -xf purple-facebook-0.9.6.tar.gz
cd purple-facebook-0.9.6/
# install systemwide
make install

Restart pidgin after that, and go to the account creation:

Facebook is here !

Do not forget to activate/configure the plugins you have installed.

Install open Jarvis on OSMC (raspbian 9.6)

Just for fun, I want to test openjarvis.

I have a Raspberry Pi with OSMC running my media center, and I use it often to try things, so this time is the turn of openjarvis.

But OSMC does not have all the needed package, and the how to install is old for openjarvis some of the package have changed.

I have not saved all my step, I think there are all here, but if you follow this and you have some issue, tell me in the comment.


sudo apt-get install -y git # install git if you don't have it already - needed with OSMC
git clone
cd jarvis/

To use snowboy without needed to build it for your system, you can do this dirty hack, it’s just for testing and fun, at your own risk 🙂

In the stt_engines/snowboy/ file, you delete ligne 14 and 17 (you delete the IF condition on the debian_version)


elif [ "$jv_os_name" == "osmc" ]; then #628
            if [[ "$(cat /etc/debian_version)" -ge 8 ]]; then


elif [ "$jv_os_name" == "osmc" ]; then #628

Before launching ./ you need to install alsa-utils, and libttspico-utils

sudo apt-get install alsa-utils libttspico-utils

If I have forget nothing, you can launch ./ and the installation will succeed 🙂
