The present gist is a hybrid between a 'go-to' cheat sheet and a tutorial when starting a new Data Science Project.

Its purpose is to create a virtual environment for Python with the package manager Conda.

Development Phase:

Step 1: Create Certificate .pem from Certificate .p12
Command: openssl pkcs12 -clcerts -nokeys -out apns-dev-cert.pem -in apns-dev-cert.p12

Step 2: Create Key .pem from Key .p12
Command : openssl pkcs12 -nocerts -out apns-dev-key.pem -in apns-dev-key.p12

Step 3: Optional (If you want to remove pass phrase asked in second step)
Command : openssl rsa -in apns-dev-key.pem -out apns-dev-key-noenc.pem

Custom Alloy Tags based on Appcelerator Hyperloop modules

With Alloy and Hyperloop, you can quickly and easily expose native UI as Custom Alloy tags by leveraging the namespace (ns) attribute and commonjs modules.

Alloy allows you to create your own UI element that can be included into the XML View heirarchy in one of two ways, an Alloy Widget or through the use of Custom Tags.

To create your own custom tag, you link the tag to the commonjs module with the namespace attribute (ns). Here is an example using a custom tag to render a standard Titanium View:
