How to work with Python applications and modules in Yocto

Python is one of the most popular programming languages used today and it has been around for more than 2 decades. It is commonly used in the development of applications for IoT and especially in the early stages of product development while developers might still be evaluating projects. The reason for its popularity is because Python is easy and quick to develop, for example the logic is closer...

How to update a Docker container with Mender using Raspberry Pi

A Docker container packages applications in containers by virtualizing the operating system and dividing it into compartments to run applications. Powerful CPU-based devices can leverage virtualization to enable containers. Containers are easy to manage due to their atomic nature, enable more efficient use of system resources, faster delivery cycle and provide a nice layer of isolation. Microsoft...

How to do delta (differential) updates with Mender

Using binary deltas for applying updates is a more efficient mechanism for updating software over-the-air (OTA) which enables faster downloads and bandwidth cost saving for metered networks. When using cellular (e.g. 4G/LTE) or other bandwidth constrained networks, the impact is even greater. With the recently announced commercial editions, Mender offers the ability to generate and only deploy t...

Enabling faster downloads and lower bandwidth costs over cellular networks with Mender robust delta updates

Delta update is a more efficient mechanism for updating software over-the-air (OTA) when using cellular networks (e.g. 4G/LTE) which enables faster downloads and bandwidth cost savings. Mender offers the ability to generate and only deploy the difference (delta) between the software version already on the devices and the new version, on the binary level. Depending on the cellular technology and ne...
