On December 7, 2021, Amazon’s cloud services recently suffered a major outage that not only affected Amazon services, but also many third-party services we use day-to-day, including Netflix, Disney+, Amazon Alexa, Amazon deliveries and Amazon Ring. Causes for the outage, which began at 7:30 am PST and lasted nearly seven hours, were detailed in a Root Cause Analysis report published by AWS that shed light on factors that may have contributed to the extended length of the disruption.

Dirty Pipe vulnerability is a Linux kernel vulnerability that allows the ability of non-privileged users to overwrite read-only files. The vulnerability is due to an uninitialized “pipe_buffer.flags” variable, which overwrites any file contents in the page cache even if the file is not permitted to be written, immutable, or on a read-only mount, including CD-ROM mounts. The page cache is always writable by the kernel and writing to a pipe never checks any permissions.

Developers use JavaScript frameworks like Angular, React, and Vue.js to build every kind of single page application, from simple to complex. By separating JavaScript and CSS, frameworks let dev teams structure applications in modular chunks of code that carry out a single function. That is great, but once your application is ready for deployment to production, you will need a command to compile and bundle the separate files into a single one.

TL;DR: startSpan is easier and measures a duration. Use it if your work won’t create any subspans. startActiveSpan requires that you pass a callback for the work in the span, and then any spans created during that work will be children of this active span. I’m instrumenting a Node.js app with OpenTelemetry, and adding some custom instrumentation. For this important activity that I’m doing (let’s call it “retrieve number”), I’m creating a custom span.
