Some time ago, I discovered that terminal emulators are not only capable of displaying text, but can also display images. Unfortunately, it's a rarely used and underestimated feature, despite the possibilities it offers. In the past I have used this to quickly visualise my DSP algorithms. In the following article I'll give you an example of how to do this with iTerm2 using the "iTerm2 Inline Images Protocol".
In the future, I'll describe how to display images in terminals that support the "Sixel" protocol instead (which are actually the majority).

If you are working with microservices, you may be interested in log correlation. It's a technique that allows you to group logs related to the same incoming request, even if the request is processed by multiple services. It's very useful for identifying sources of problems in distributed systems.
