June 28, 2024Eystein Stenberg from Mender.io
Available on your favorite podcast platform.
Great discussion with Eystein on updating systems, how Mender has evolved over
the last ~10 years, and more:
Eystein has a background in Math and cryptography
Company started as CFEngine
Things people tend to not think about with system update:
security
reliability (power loss, does it resume downloads when there are network
issues, etc.)
future products -- is the solution general
scheduling
updating multiple devices in the system
Mendor milestones
OSS release
SaS service
advanced environments, complex deployments, orchestration, etc
OSS foundation
open-core model
product led growth
is working well
Programming languages
Switching the Mender client from
Go to C++
so the client is more portable.
Platform vs Product
Product -- narrow set of problems, pick what you need, less vendor lock-in
Platform -- wide focus and tends toward locked in
Interesting in the technology space
Bootloader standardization would help a lot
ARM System Ready
looks interesting.

Available on your favorite podcast platform.
In this episode, we had a great discussion with
Drew about:
Drew's career -- many interesting companies
Toradex
manufacturers SOMs (System-on-Module)
started out providing WinCE solutions
Torizon
opinionated stack
fully integration solution
container runtime -- allows developers to deploy applications without
knowing much about Linux
customize OS without doing Yocto builds
Visual Studio Code plugin
simplifies management of Docker images, containers, cross compilation,
remote debugging, etc.
Torizon device side software is OSS
SW update system
many options: Mendor, RAUC, SWUpdate, OSTree
Toradex uses OSTree
OSTree is file based for delta updates, where RAUC and SWUpdate are block
based.
single partition
Git-like store where changes can be rolled back, etc.
read-only rootfs
Uptane is provides protection against attackers
Greenboot -- used to verify system is functioning properly
Toradex's upstream first policy
Challenges in developing with Embedded Linux
drinking from the OSS firehose
understanding all the components
realistic expectations about how long this stuff takes to develop
regulations
The future
