> Apple is the only one that refuses to publish any dates. I don’t mean to defend Apple here, but one reason Apple may do that is because they essentially consider themselves a hardware company, and so the things they support are device models, not software versions. For me, a good-enough approximation has been that you can consider a macOS version [major dot minor] to be supported until the day [major dot (minor+1)] comes out, or the day [(major+3) dot 1] comes out, whichever happens earlier [1]. (Full disclosure: I’m the author of that merge request.) [1]: https://github.com/CISOfy/lynis/pull/1006

* Project name: Lynis (https://github.com/CISOfy/lynis/), GPLv3 * Project description: security auditing tool for Linux, macOS, and UNIX-derivatives. The primary goal is to assist in security assessments and help with system hardening. Written in shell script and project is mature (almost 9 years). * Upcoming goals: More application specific tests (like MongoDB, Redis, Tomcat, nginx), so we can provide more value as a project. * Needed skills: application knowledge and able to write some basic shell script. * Contributors link: https://github.com/CISOfy/lynis/blob/master/CONTRIBUTIONS.md * Your license(s): GPLv3
In Ask HN: Who needs contributors? (October 2016)
At our company (CISOfy) we created a solution around our existing open source project Lynis (https://github.com/CISOfy/lynis). This way the tool in itself provides value, yet the separate Enterprise offering as well. Lynis itself is useful for a single system, yet companies might be attracted by Enterprise features (like collecting all data centrally, dashboards, reports, compliance reporting). A similar way might work for your web application, by making two different products, each with their own audience. My tip as founder: start testing the viability of your product/business first. Consider the reasons why people would or would not pay. Ask people in your field who might use it and if they would be willing to pay (and how much).
