MongoDB, A Database For Document Stores
A potential prey for Oracle or Microsoft, MongoDB leads the document store market, and is now ranked #5 among all DBMS (source: DB Engines). It is at the heart of the DECODER PKM and also of multiple one-page websites based on the MEAN stack (Angular, MongoDB, Express, NodeJS).
In a recent article, Eric Weiss, Analyst at several large banks, sees MongoDB as the clear-cut leader within the high-growth, non-relational database SaaS sector. "MongoDB has been and will continue to be an indirect beneficiary of high-growth megatrends such as AI, Machine Learning, IoT (Internet-of-the-Things) and digitalization. Each of these trends have sparked an exponential growth in supply of unstructured data resulting in an increasing demand for (NoSQL) non-relational database solutions. Such databases can much more efficiently handle this new flow of data workloads compared to more traditional relational, SQL-based solutions".

Big Code has a direct impact on the business outcomes
For developers, code releases are "emotional" events. Many have fear and anxiety at the moment they release code or submit it for review and fear breaking dependencies.
Indeed, managing large and complex code bases (Big Code) can become laborious, time consuming and costly. Joe McKendrick article refers to a 2020 survey of 500 north American professional developers compiled by Dimensional Data and underwritten by Sourcegraph. The Emergence of Big Code survey highlights a dramatic growth in the volume and complexity of software code.
It's almost unanimous: 99% of respondents report that big code has a direct impact on the business outcomes of software development efforts. Challenges include less time for new hires to be productive (62%), code breaking due to a lack of understanding of dependencies (57%), and difficulties managing changes to code (50%).

Machine Learning for Cybersecurity
Automated Vulnerability Detection in Source Code Using Minimum Intermediate Representation
Vulnerability is one of the root causes of network intrusion. An effective way to mitigate security threats is to discover and patch vulnerabilities before an attack. Traditional vulnerability detection methods rely on manual participation and incur a high false positive rate. The intelligent vulnerability detection methods suffer from the problems of long-term dependence, out of vocabulary, coarse detection granularity and lack of vulnerable samples.
This paper proposes an automated and intelligent vulnerability detection method in source code based on the minimum intermediate representation learning.

Distinct AI Techniques Bring Different Business Values
Machine learning and deep learning are often conflated by business decision makers. Machine Learning can involve a wide variety of techniques for building analytics models or decision engines that don't involve neural networks, the mechanism for deep learning. And there is a whole range of AI techniques outside of machine learning as well that can be applied to solve business problems.
Do you leverage these techniques or do you prefer computer vision and natural language processing applications to solve your business problems?

An MLOps approach to bring models to production
Machine Learning Open Studio and Model as a Service (MaaS) from Activeeon helps data scientists and IT operations work together in an MLOps approach allowing to bring ML models to production. Machine Learning Open Studio includes automatic data drift detection mechanisms and allows traceability and audit over model performance to retrain it when necessary.
Only a small percentage of ML projects make it to production because of deployment complexity, lack of governance tools and many other reasons. Once in production, ML models often fail to adapt to the changes in the environment and its dynamic data which results in performance degradation.
To maintain the prediction accuracy of ML models in production, an active monitoring of model performance is mandatory. This allows to know when to retrain it using the most recent data and the newest implementation techniques, then redeploy in production. More...

Clear Linux OS automates the creation of RPM packaging
Designed by Intel and open source contributors, the Clear Linux OS delivers a secure, hardware optimized OS. Its updates ensure that software dependencies remain mutually compatible.
The autospec tool is used to assist with the automated creation and maintenance of RPM packaging in Clear Linux OS. Where a standard RPM build process using rpmbuild requires a tarball and .spec file to start, autospec requires only a tarball and package name to start.
Recent reviews confirm the performance an stability improvements of Clear Linux OS. However, software that are packaged in other formats for other Linux distributions are not guaranteed to work on Clear Linux OS and may be impacted by Clear Linux OS updates.

NLP Search Paves the Way for Augmented Data Discovery
Combining natural language understanding and natural language generation will result in dynamic, bi-directional human-machine communication that will take several forms: text, voice and images. In text and voice scenarios, the BI or analytics solution can converse with the user to render the desired result - regardless of data-related and query-related search complexity.
Data visualizations also will become more interactive, if not immersive, along the lines of Busby from Oblong Industries. This product focuses on immersive interfaces, not specifically BI or analytics. However, its concepts could have a ripple effect on how people interact with data and thus, augmented data discovery.
"I think the future of BI is no BI. Don't ask me to search and look for things anymore. Give me that piece of information when I need it and if I need it. Come to me when there's something I need to know", foresees Erick Brethenoux, senior director analyst at Gartner.
