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 Technologies such as ZeroVM which provided a brilliant solution are no longer maintained.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?

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.

Five Evolutions of Cloud Computing

Cloud Computing is essentially the automation of IT service provisioning through software which replace human tasks. It is currently evolving in multiple directions. Free Software and Open Hardware will eventually lead to massive price cuts compared to current price levels in USA or Asia. Edge Computing will reduce the need of data centres whenever network latency or availability become critical. Service Workers will eliminate the need of servers, both at the edge or at the data centre, in 90% cases. Big Servers will eventually replace smaller servers as the standard fabric the data centre.

OfficeJS Iodide: Ubiquitous Data Science Notebooks for Business and Education

Iodide and Pyodide have brought a standard notebook application to OfficeJS that can be used for business reporting, research and education. They support data science libraries such as NumPy, Pandas, Matplotlib, Plotly, etc. and soon scikit-learn. OfficeJS Iodide notebooks can be used offline or online on any modern HTML5 web browser such as Firefox or Chrome. Thanks to JIO, notebooks can be synchronised with Dropbox, WebDAV, ERP5 and any other storage supported by a JIO plugin. Iodide notebooks can also be embedded through RenderJS into any business application. The dream of ubiquitous data sciences at no infrastructure cost has come to a reality.

How Nexedi moved to HTTP2 with Caddy

After trying and failing to move to HTTP2 using Apache in 2017, Nexedi has adopted Go language based Caddy server. Initial results of HTTP2 show significant speed improvement and good stability. Next step will be the adoption of QUIC. Migration was smooth and entirely automated thank to a test driver devops approach recently introduced in SlapOS.

Python multi-core benchmark in uvloop context

The existence of cython combined with a clean concurrency model based on technologies such as gevent and pygolang could change the situation if both can be tightly integrated into cython's static cdef code rather than scattered as it is today.

Optimising MariaDB for Big Data

MariaDB is used at the core of ERP5 and Wendelin. Thanks to NEO distributed object store, MariaDB can store hundred terabyte of big data information such as wind turbine vibration, noise, server logs, etc. We explain in this blog how we currently optimise MariaDB to obtain good results and what remains to be done at the core of MariaDB to reach even further scalability.

High Peformance Multi-core Python at Nexedi

Nexedi has been able to use python language in a multi-core high performance fashion for over 10 years. We explain how in this blog and provide a simple set of rules to quickly remember how and why python is suitable for concurrent programming. We also explain our decision to use golang in rare cases where python is not suitable.
