Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

86Box crashes on startup of any virtual machine
86Box crashes on startup without showing any message, no matter the hardware or operating system being emulated and 86Box build, either stable, experimental or old/new dynamic recompiler. Created an issue on GitHub but the dev who replied said he couldn't reproduce it.

Virtual Machine for old childhood Rom games
For emulation, you can look into PCem/86Box

Fake recruiter Lazarus lured aerospace employee with trojanized coding challenge
Unsurprising, of the 300 staffing agencies in our area only 23 are actually licensed to legally operate as a service. Trying to authenticate which are "fake" or "real" is a thread most companies/applicants rather not pull.
There is also the fake-hire scam: where staff are lured away with a lucrative compensation packages, data-mined by the competitor, and finally jettisoned before the evaluation period expires (typically 6 to 10 months).
A few infected PDFs from various bad actors are also floating around out there with exaggerated promises.
Keep safe, and note 86box supports read-only backing images and sessions Like Bochs/kvm:

Where does PCem store the Hard disk you create? I want to move it to a different location and can't find it.
Features are implemented much, much faster, especially if you use nightly builds. Always adding hardware. You can look at the changelog: https://github.com/86Box/86Box/releases

86box crashing when using shaders?
Shaders are a rather young feature in 86box and very incomplete (only single pass shaders supported for now). I am not surprised they crash. Please report the bug to https://github.com/86Box/86Box/issues

I’m wondering if someone would be interested in helping my get an old windows 95 game to run.
Another solution is to emulate a win95 old pc. It works great and the compatibility is very very high. Try out 86Box. There is a process to set it up and install Windows, but it is worth it for playing stubborn games.

Getting vintage (old world) Linux distro’s installed on modern virtualization software impossible?
You want 86Box, a full PC emulator as opposed to a virtual machine.

The History of Xenix
“Despite this reduction in scope for MS-DOS 2.0, it did carry many bits of XENIX. The system adopted I/O redirection via less-than and greater-than symbols, piping, a hierarchical directory tree, file handles […]”
The source code for MSDOS 2 is available and the file descriptor stuff appears to be in https://github.com/microsoft/MS-DOS/blob/master/v2.0/source/... and XENIX2.ASM. It stands in contrast to the File Control Block API which MSDOS 1 (née 86-DOS) modeled after CP/M’s API.

MS-DOS is now open-sourced
Asynchronous I/O figures in prominently in Windows NT. I was really surprised to see[0]:
Each driver in the chain defines two entry points; the strategy routine and the interrupt routine. The 2.0 DOS does not really make use of two entry points (it simply calls strategy, then immediately calls interrupt). This dual entry point scheme is designed to facilitate future multi-tasking versions of MS-DOS. In multi-tasking environments I/O must be asynchronous, to accomplish this the strategy routine will be called to queue (internally) a request and return quickly. It is then the responsibility of the interrupt routine to perform the actual I/O at interrupt time by picking requests off the internal queue (set up by the strategy routine), and process them. When a request is complete, it is flagged as "done" by the interrupt routine. The DOS periodically scans the list of requests looking for ones flagged as done, and "wakes up" the process waiting for the completion of the request.
I didn't realize that kind of forwarding-looking perspective was going into the design of MS-DOS.
