Recent trends in process isolation technologies

Efficient process isolation and portability is still an open problem. Technologies such as ZeroVM which provided a brilliant solution are no longer maintained. Alternatives are emerging: V8: Isolates, Firecracker, gVisor, OSv. Which one could make sense in the context of Nexedi stack?

Are Linux containers stable enough for production and why Nexedi uses SlapOS nano-containers instead ?

Nexedi does not use LXC containers or docker because it is impossible to ensure their stable operation especially in case of kernel ABI mismatch or missing containerisation of system calls. Instead, we use SlapOS nano-containers which have provided since 2010 similar benefits in a more stable way while using less resources. SlapOS nano-containers will soon be deployed on embedded device using Elbe embedded Linux with over-the-air (OTA) upgrade and secure boot.

Using an /e/ phone as a desktop or laptop

Not so much work remains to be done to turn /e/ into a desktop operating system. Using an /e/ smartphone as a desktop PC with an external screen, keyboard and mouse is already possible with good usability. Using an /e/ smartphone as a laptop is also possible with scrcpy although some minor improvements are still required for usability.

Can Free big data regulate AI and the data economy?

Market does not seem to provide any valid solution to the new issues posed by a data economy which is characterised by a combination of increasing returns and legal blockers to community or ecosystem based competition. As a consequence, the current known optimal organisation to monetise big data and A.I. is the private or state monopoly. We review in this article possible alternatives that could be considered in the future and how to enforce them.
