Download a cacert.pem for RailsInstaller

Why?

There is a long standing issue in Ruby where the net/http library by default does not check the validity of an SSL certificate during a TLS handshake. Rather than deal with the underlying problem (a missing certificate authority, a self-signed certificate, etc.) one tends to see bad hacks everywhere. This can lead to problems down the road.

From what I can see the OpenSSL library that Rails Installer delivers has no certificate authorities defined. So, let's go fetch some from the curl website. And since this is for ruby, why don't we download and install the file with a ruby script?

Installation

The Ruby Way! (Fun)

UDID, identifierForVendor and advertisingIdentifier FAQ

What's the difference between UUID, GUID and UDID?

  • UUID (Universally Unique Identifier): A sequence of 128 bits that can guarantee uniqueness across space and time, defined by [RFC 4122][rfc4122].

  • GUID (Globally Unique Identifier): Microsoft's implementation of the UUID specification; often used interchangeably with UUID.

  • UDID _(Unique Device Identifier)): A sequence of 40 hexadecimal characters that uniquely identify an iOS device (the device's Social Security Number, if you will). This value can be retrieved through iTunes, or found using UIDevice -uniqueIdentifier. Derived from hardware details like MAC address.

Is UDID deprecated?

Git Submodules basic explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

  • Separate big codebases into multiple repositories.
