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: 11 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

You can try Slax as it can be loaded to RAM. However you will need to install rest of the required utils... (afaik Chrome and GParted are included by default). Source: over 2 years ago
