By creating a Certificate Authority (a.k.a., a “CA”) and trusting it locally, any certificate that we create using this CA will also be trusted locally. This can simplify the development of HTTPS websites on your local machine. This content is a fork of, and is largely based on, “Generating Self-Signed SSL Certificates for Use with Bluemix Custom Domains”, by Tony Erwin, dated 2014-09-15. The examples in this tutorial are from macOS Sierra (10.12). Create a local Certificate Authority Start by opening Keychain Access.

macOS is a Unix, and not built on Linux. This can bite you when trying to write scripts which support both platforms. I think most of us realize that macOS isn’t a Linux OS, but what that also means is that instead of shipping with the GNU flavor of command line tools, it ships with the FreeBSD flavor. As such, writing shell scripts which can work across both platforms can sometimes be challenging. Homebrew Homebrew can be used to install the GNU versions of tools onto your Mac, but they are all prefixed with “g” by default.

Overview aws-vault is a tool for storing your AWS credentials in your system keychain instead of as a plain text file on-disk. Credentials and other secrets (including your various system passwords) are stored inside your system keychain. They are encrypted, and cannot easily be stolen by a rogue script or application. By keeping your AWS credentials in your system keychain, they are available to you when you are logged in, unavailable when you are logged out, and provide an important layer of security that the standard plain text storage method does not.

Apple’s October 16th product announcement begins at 10am PST; 1pm EST. My guesses? Definitely: OS X Yosemite, iTunes 12, and the next-gen iPad Air and iPad mini. Maybe: Updated Thunderbolt 2 + Retina display (I’d guessed at this last year and was wrong), iMac with Retina display, updates to the MacBook Pro line, Apple TV 4 with support for third-party apps. Not a chance: An HDTV, more info about Apple Watch, a mega-sized iPad, or a pull-string-to-talk Steve Jobs doll.

Last month, when writing about Apple’s Fall 2013 Product Announcement, I’d guessed at a few announcements that they didn’t end up making. Today, Apple announced all of those things and more. OS X Mavericks OS X 10.9 ”Mavericks”. Available today. Free (down from $19.99 last year). MacBook Air Lighter and faster than the last model. Faster 802.11ac wireless networking, Bluetooth 4.0 and Thunderbolt 2. Available today. Starting at $999. MacBook Pro with Retina Display Lighter and faster than the last model.

Apple’s fall product announcement begins at 10am PST; 1pm EST. My guesses? Definitely: Next-gen iPhone 5S, iOS 7, OS X Mavericks, iTunes 11 (with iTunes Radio), updated MacBook Pro. Maybe: New iPads (though I’d bet on spring instead), lower unsubsidized-cost iPhone for other (non-American) countries, updated iMac, updated Thunderbolt 2 display (with USB 3.0). Not a chance: An HDTV, a wrist-watch, a pull-string-to-talk Steve Jobs doll. How’d I do? How good were my predictions?
