Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096

macOS Internals

Understand your Mac and iPhone more deeply by tracing the evolution of Mac OS X from prelease to Swift. John Siracusa delivers the details.

Starting Points

How to use this gist

You've got two main options:

Manage Neovim plugins (and more!) with Nix and Home Manager

Highly extensible software like Emacs, Vim, and Neovim tend to grow their own package managers. A software developer, for example, might want to install editor plugins that hook into a particular programming language's linter or language server. The programmer's text editor is therefore extended to support managing additional software to extend the text editor. If this loop continues for too long, the programmer's editor becomes more delicate and complex. The remedy for this problem is to manage software using dedicated tools apart

Digital Car Key:

Has three sections.

defaults: {
    “com.apple.MobileBluetooth.debug” =     {
        ExtraZoningLog =         {
            EnableZoneLogging = 1;
        };
        FWStreamLogging =         {

chroot Environments on macOS

This is a draft.

macOS doesn’t have many of the advanced Linux or UNIX features that have come about in the past 20 years. So getting a proper chroot environment up and running takes a little more work.

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git
