Thanks for your work on Haiku.
I remember LOVING BeOS when it came out. I was a kid, had dabbled in breaking my parents computers with Linux distributions in the 90s, and was enamored with BeOS and was blown away by how great it worked. The fact that the user space has continued over the years is really nice to know (and have tried over various times through emulation).
Has there ever been interest or attempts at funding it so that more than a man-month could get accomplished?
We had two major contracts (for a few months) in 2012-2013 to finish and then integrate the package management system, another in 2013 for the new kernel scheduler, and then one that lasted almost a year around the same time working on the WebKit port used in the built-in web browser (which ended because the money ran out.)
Haiku, Inc. currently has over $100k in the bank as per it's last financial report, but at only $20k (usually less) in donations a year, it's obviously not enough to be sustainable past a year or two for even a single developer. If there was actual sponsorship by the community or otherwise, then yes, a number of us would be willing to work on Haiku full-time.
I myself am not exactly sure what I'd like to use Haiku for. I'd probably consider it if I had two different systems, one for development (which I need to use Linux for) and one for everything else (I just need LibreOffice and a usable browser).
Overall, we are in a kind of "valley" of sorts: Haiku, Inc. gets more than enough money to pay for infrastructure and occasional miscellaneous things like that, but a long way away from enough to hire someone full-time for an indefinite period, and it's difficult to get people to contribute larger sums for a full-time developer that may become possible in half a year, two years, or ten years.
