The Dynatrace third-party vulnerabilities feature provides insights into vulnerable software packages by matching detected package identifiers and version numbers with known vulnerable software packages and related common vulnerabilities and exposures (CVEs). The risk of impact from an existing known vulnerability also depends on whether certain processes are using the vulnerable parts of a software component.

For the longest time now, I have been obsessed with caching. I think every developer of any discipline would agree that caching is important, but I do tend to find that, particularly with web developers, gaps in knowledge leave a lot of opportunities for optimisation on the table. How does it affect you? Want to know everything (and more) about HTTP cache?

I recently compared three OpenTelemetry approaches on the JVM: Java Agent v1, v2, and Micrometer. I used Kotlin and coroutines without overthinking. I received interesting feedback on the usage of @WithSpan with coroutines: Indeed, the @WithSpan annotation has worked flawlessly in conjunction with coroutines for some time already. However, it made me think about the underlying workings of OpenTelemetry.

Data centers use a lot of electricity. Consequently, as they grow, it becomes all the more important to understand their energy use and take steps to reduce it. Learning to measure data center power usage effectiveness (PUE) is a crucial part of that goal. What Is Data Center Power Usage Effectiveness? As its name implies, PUE measures how efficiently a data center uses the energy it consumes.
