A blast from the past – Amit Singh

I spent most of today tied up with working on getting an upspin instance operational again. Instead of running things as a standalone daemon, I proxy through a web server so that the upspinserver can run as a unprivileged user, on a unprivileged port and everything should be good and happy. Except it’s not, on the client side is macOS with osxfuse and the upspin space expose to the OS via upspinfs, browsing works great, manipulation through finder, not so much. You can copy a file in to place and when the transfer is finished, the file disappears from finder however the upspin tool is able to show things correctly as they should appear. I spent some time looking in to the osxfuse source repositories and installer package as there is a separate repo for the kext which I wondered where it fits in, in a world with SIP.

While going through the osxfuse source, Amit Singh’s name popped up in the licenses. I was a big fan of his blog kernelthread.com when it was active and would look forward to new posts. I fondly remember trying out the test app he wrote to demonstrate the sudden motion sensor working on Mac OS X with my 17″ PowerBook G4 and the posts to complement the Mac OS X Internals book.

Turns out he gave a talk at Google back in the day on MacFuse which is the predecessor to osxfuse.

It’s a nice talk which provides some history on how the project came about and why he decided to work on it, there were moments which made me smile especially when discussing conditioning and deeply held (mis?)beliefs.

I also found that Apple still runs their mailman instance with a small number of list being served from it, most importantly Darwin related ones. šŸ™‚

Back to more wrestling tomorrow, gnite!
