Here is the recipe I’ve made recently to integrate Kivy 2.0.0 in Yocto (dunfell). It’s probably far from perfect, but I guess it can help other Yocto+Kivy users like me. Note that I had to patch the setup.py of Kivy to work around a bug. This bug has been fixed now, so this patch won’t be useful for future versions.

Use Ubuntu 20.04.1 (Raspbian is only available as armhf images ; we need arm64). In /etc/modules, add libceph and rbd Install K3s Clear the disks you want to use as Ceph storages As root: 1 2 3 sudo apt install ceph-common git clone https://github.com/rook/rook.git cd rook Switch to the raspbernetes images instead of the default ones. Currently the default ones are not all built as multi-arch yet and therefore don’t all work on arm64. ...

My girlfriend and me have bought the very same electric kick scooter, the Segway Kickscooter Ninebot ES-2. We have done the very same trip at the same time. Both scooters are brand new. This showcase very nicely the importance of weight regarding electric kick-scooter autonomy. Beware: This electric kick-scooter requires you to install an application on your phone. On Android, the application is available on Aptoide and works without Google services. However this application is 100% proprietary, poor quality, and clearly from China. It will publish the distance you travel somewhere without asking you first. ...

Pour un projet perso top secret, je me suis retrouvé dans une situation où je souhaitais être capable de : stocker un grand nombre de petits dépôts Git les avoir en haute-disponibilité (99.9% d’uptime) encaisser une forte charge en lecture sur ces dépôts être capable de monter en charge verticalement mais aussi horizontalement rapidement si besoin est toujours avoir un contenu apparent cohérent : Quand on fait un push sur une des machines du cluster et qu’on enchaîne sur un pull depuis une autre, il faut que le contenu du push soit systématiquement apparent accéder et manipuler ces dépôts depuis un programme en Python 3. Autrement dit, il me fallait essentiellement un moyen de répliquer des dépôts Git sur plusieurs machines efficacement. ...

Git supports various protocols. One of them is called the “dumb” protocol. This dumb protocol is based on HTTP+Webdav. There is also a smart protocol, but this one is not really HTTP compliant (it starts as HTTP for an handshake, but then switches to a custom protocol). The dumb protocol is really handy in scenarios where you can only expose a Git repository through standard HTTP+WebDav. For instance, if you have a firewall in front of your webserver. Or if you want to implement a “fake” Git repository using a standard web framework (Django for instance). ...

Hier soir, mon scanner m’a laché. Dans ce genre de situation, j’ai pris le réflexe d’ouvrir l’engin pour voir si je ne peux pas le réparer moi même. Pour le coup, j’ai pu constater que le fabriquant (HP) a été radin sur plusieurs points et que cette panne serait arrivée tôt ou tard. Il s’agit d’une imprimante multi-fonctions HP OfficeJet 4500. En gros, parmi les imprimantes multi-fonctions avec un bac d’alimentation pour le scanner, c’est la moins chère. ...
