Too Long; Didn't Read
This post has no scientific reasons about which kind of <a href="https://hackernoon.com/tagged/tools" target="_blank">tools</a> a professional needs to use. The use of these tools spans from development to operations to maintainance to marketing to support and to PR and so on. Not everything may be needed by a <strong>[your favourite technology]</strong> developer. The tools may be relevant to Internet startups. I use (or used) them for getting my work done.
