Build a subscription app with PayPal Python sdk, Flask, and Heroku

With the release of the subscription (recurring payment) APIs from PayPal, it is possible to create your anything-as-a-service buisness faster than ever. SDK integrations provide a native way to integrate with the PayPal APIs in the language of your choice. In this tutorial, we will walk through a sample application built using the PayPal Python sdk, the microframework Flask, Bootstrap for UI and Heroku for deployment.

Setting up

If you have not already, get your credentials from PayPal Developer Portal and see the Subscription api docs. Afterwards, set up the Python sdk. It may also be worth checking out Flask to see how to set up a simple web application (hello world is only 7 lines long!).

Building Realtime user monitoring and targeting platform with Node, Express and Socket.io

Being able to target users and send targeted notifications can be key to turn visitors into conversions and tighten your funnel. Offerings such as mailchimp and mixpanel offer ways to reach out to users but in most of those cases you only get to do them in post processing. However, there are situations when it would be really powerful is to be able to track users as they are navigating your website and send targeted notifications to them.

###Use Cases Imagine that a buyer is looking for cars to buy and is interested in vehicles of a particular model and brand. It is very likely that he/she will visit several sites to compare prices. If there are a few results the buyer has looked at already, there may be an item which would fit the profile of this user. If you are able to prompt and reach out as the user is browsing through several results, it could make the difference between a sale and user buying from a different

2015 NodeConf Notes

NodeConf 2015 (June 11-13)

###Isomorphic JS

  • challenges/tradeoffs in writing identical code client/server side
  • write once, render anywhere
  • State does not live in the template
  • existing problem in server side rendering - how to present local timezone that represents client without passing client's timezone
  • Serving side is first class citizen in React
  • ways people have been getting around polyfills on polyfills, leveldb-browserify, leveljs

Apple TV Tech Talk in Austin December 15th

##Takeaways

  • Early trends: PhotoAlbum, On Demand TV, Games, Photo heavy apps e.g. Airbnb, Education for children
  • Apple puts a significant amount of preparation into their presentation. They follow a prompt and all talks follow exact same format.
  • It is early for tvOS but the constraints are interesting. Always connected device, need to access much bigger volume of resources.
  • Emphasize making an app designed for living room
  • tvOS app store has about 40% paid apps as opposed to 10% on iOS, but early to draw conclusion.
  • The framework provides utilites tailored specific to tv experiences, subtitles, playback, ratings, product catalogue information etc.
