This nginx configuration allows to restrict access via different methods to separate users.

This is very useful for private docker registries, where you want every member of your team to be able to fetch Docker images, but only some users (admins and CI users) to push new images to the registry.

Example:

• User write can use GET, POST, PUT, DELETE and everything else.
• User read can only use GET and HEAD.
• Anonymous users are denied access entirely.

# An overly complicated SIP config checker

# This is a technically interesting implementation because it does not rely on csrutil
# Instead it queries the kernel directly for the current configuration status
# This means, for example, in environments where SIP has been disabled and csrutil has
# been removed or modified (say, with DYLD_LIBRARY_PATH), as long as python can run you
# can still check status

# Additionally, checking the nvram csr-active-config setting isn't accurate now with
# 10.12.2+, since running "sudo csrutil clear" deletes the variable until reboot,

ld – Wading through Mac OS X linker hell

Intro

Friend: I tried looking at static linking in Mac OS X and it seems nearly impossible. Take a look at this http://stackoverflow.com/a/3801032

Me: I have no idea what that -static flag does, but I'm pretty sure that's not how you link to a library. Let me RTFM a bit.
