Fix `sudoers` Issue on macOS Catalina

If you messed up with editing sudoers, this solution is for you. The solution is limited to restoring /etc/sudoers file to the original state. It is easier to mess up your config such as saving wrong format, etc.

How to Fix

Please reboot your macOS into recovery mode. While rebooting press and hold Cmd+R key.
After you completely reboot, you will see a dialog. You need to open Terminal by clicking Utilities > Terminal on menu.
In order to mount /etc as writable state, you need to disable SIP first by executing csrutil disable.
Reboot into single user mode. While rebooting press and hold Cmd+S key.

This page is a curated collection of Jupyter/IPython notebooks that are notable for some reason. Feel free to add new content here, but please try to only include links to notebooks that include interesting visual or technical content; this should not simply be a dump of a Google search on every ipynb file out there.

Important contribution instructions: If you add new content, please ensure that for any notebook you link to, the link is to the rendered version using nbviewer, rather than the raw file. Simply paste the notebook URL in the nbviewer box and copy the resulting URL of the rendered version. This will make it much easier for visitors to be able to immediately access the new content.

Note that Matt Davis has conveniently written a set of bookmarklets and extensions to make it a one-click affair to load a Notebook URL into your browser of choice, directly opening into nbviewer.

what i wish jai had:

better "standard library" (odin's core+vendor libraries/jai's compiler modules)

odin's interface for things is very intuitive and very well designed, it doesn't take long to find what you're looking for, and it's very consistent. for example, strings.builder_make(), strings.builder_init(), strings.builder_destroy(), etc. meanwhile in jai you have things like String_Builder procs: init (which could refer to any number of procs because overloading) print_to_builder, free_buffers/reset, append, etc. (there are more examples like this in other modules.) once you find what you're looking for, it works great, but odin's core library discoverability is top notch (especially with https://pkg.odin-lang.org/ exisiting)
slice syntax

jai has "array views" which are exactly like odin slices. but odin's way of handling them with the python syntax makes it 10x more usable, rather than having to use array_view(*view, 0, count) everywhere, and lets you not depend on pointer arithmetic like jai
