You probably know about objects and arrays, but how often do you use sets and maps? This article explains everything you need to know to use these more specialized data types in your JavaScript applications.

Log4j is a popular logging framework used for Java-based applications. We can use Log4j in Selenium to provide logging functionality and help in debugging the test scripts. By using Log4j, you can log messages at different levels (e.g. Debug, Info, Warn, Error, Fatal) and output them to various appenders (e.g. Console, File, Database). Integrating Log4j in Selenium can greatly enhance the debugging experience and improve the efficiency of the testing process.

By overcoming the established engineering disciplines and tackling each engineering issue, Digital Engineering intends to speed up the development of complex products, systems, and sub-systems. System engineering approaches applied to complex products like jet planes, spacecraft, navigation systems, and others slow down progress for several reasons. Digital Engineering changed that system process into a more fluid, consistent, and workable approach for complex systems.

Fivetran’s new Quickstart data models let you turn your application data into analytics-ready tables, all with the click of a button.

Data fabric is a term used to describe a set of technologies and practices that enable organizations to manage and access data across multiple platforms and environments. This includes supporting an organization’s need to break down data silos, gain more insight into metadata, optimize data sharing across apps and data platforms. Organizations are starting to explore more flexible ways of managing their data ecosystems and ensuring they can leverage data more effectively.

Grafana Faro and xk6-browser are both new tools within the Grafana Labs open source ecosystem, but the pairing is already showing a lot of potential in terms of frontend monitoring and performance testing. Faro, which was announced last November, includes a highly configurable SDK that instruments web apps to capture observability signals that can then be correlated with backend and infrastructure data.

The cost of DNA sequencing continues to decline exponentially. With the average cost of sequencing mammalian DNA hovering around $1,000 in the beginning of 2023, startups like Ultima Genomics and Illumina are working to decrease the cost to between $100-$200. That’s about the same as a new pair of Brooks running shoes! As the sequencing cost drops, the quantity of genetic data to study and analyze explodes, making it even more important to leverage machine learning techniques.

DevOps was started more than a decade ago as a movement, not a product or solution category. DevOps offered us a way of collaborating between development and operations teams, using automation and optimization practices to continually accelerate the release of code, measure everything, lower costs, and improve the quality of application delivery to meet customer needs.
