Haiku VS Illumos

If you go to osnews.com and do a search for QNX, you will find many articles that were written over the past 20 years that describe the features, and pros and cons of running QNX. I believe there was also an article that compared BeOS (reborn as Haiku OS, haiku-os.org) and QNX. Source: 10 months ago

I am in a similar position. I'm not using the very latest C++ features, but maybe this will be of use to you anyway? I decided to get started writing a native app for Haiku (http://haiku-os.org/), which you have to write in C++. So I loaded it up in a VM and started plugging away. I have always avoided CMake, but it's so popular these days that I decided to give in and get comfortable with it. Haiku is really... - Source: Hacker News / over 1 year ago

{Yes - I know what I'm about to post is NOT "Linux" ...but if you're wanting to learn something new and/or have some nostalgia for the late-90s/early-00s, read on} I absolutely LOVED BeOS back in the day Though I understand why Apple chose to buy NeXT instead of Be in the 90s, I wish they'd bought both - NeXT to get Steve Jobs and NeXT's way of managing apps (where they're all self-contained... - Source: Hacker News / almost 2 years ago

There's a CVS commit account that can be followed on the FediVerse. * http://www.mirbsd.org It's DragonFly BSD, not Dragon BSD, and the irony of that is that you missed FreeBSD, which is of course still going. * https://dragonflybsd.org * https://freebsd.org As... - Source: Hacker News / 11 months ago

Its successor is still out there: Illumos. Though it seems to be mainly focused on backwards compatibility for existing custom applications as it still enforces things like an 8 character username limit. Source: about 1 year ago

By contrast, if you replaced the usage share of Windows with that FreeBSD you and that of macOS with, say, illumos, I would care not one bit, because this wouldn't threaten my rights. FreeBSD respects user freedom, and so does illumos. Source: over 1 year ago

All the Solaris family like illumos and openindiana. Source: over 1 year ago

Why? There is already an active open source fork of Solaris with better licensing terms than what Oracle offers - Illumos / OmniOS - https://illumos.org/ . - Source: Hacker News / about 2 years ago
