Speaking for file server wows, I had built SpecViewPerf for OS X, as from time to time I like to check and see if any Quadro/FireGL features have ever been unlocked in the Mac drivers.
I uploaded it to my Google Drive, and now it seem to be gone?
I don't know what to make of it, maybe it's still there and I'm just not seeing it, or Google just took it down thinking it was a form of copyright violation, and it may have been, I never read the license.
However it's a real pain in my ass next time I want to run it, as the patch I used to port it was only reachable in the wayback machine, and it would only build in 10.4 or below.
I had to setup a build env on 10.4 in VirtualBox, and that was a real pain too.
I'd really like to get DVD SP for OS 9 off the ADrive, but I too just get the file busy.
ADrive lets you put your stuff up, then wants to charge everyone to download it.
