Installing and configuring JenkinsCI with Nginx

JenkinsCI nginx ubuntu and digital ocean

Overview

JenkinsCI is an open source, enterprise grade continuous integration server.  It has a large and  active community of contributors and supporters, especially from within enterprise technology space. With over 300k global installations and more than 2000 community plugins JenkinsCI is a very popular choice for automating software delivery lifecycles.

This post will walk you through a hands-on installation and configuration of JenkinsCI to be run in your own environment. We will make this installation production ready by adding additional load balancer and by configuring user management capability of JenkinsCI.

How do you build mobile payments engine?

how to build mobile payments engine

Summary

There are several mobile payment libraries out there. Stripe, BrainTree, PayPal and others. The majority of them are well built and do provide mobile application developers with the straight-forward functionality of capturing payments. Developers do benefit from the inbuilt security and in many cases authentication.

But what if you had to build such library yourself and from the ground up? What would be the main components? How would they fit together?

This blog post covers exactly that – example components needed for any mobile payments library or SDK. And how do they fit together. You are most welcome to join the discussion.

OAuth and mobile commerce applications

OAuth and mobile commerce applications

OAuthorized

In this post I will take a look at what purpose OAuth authorisation protocol serves, how it is being used in mobile application world and how is it relevant to a mobile commerce applications. The first part of the post  describes most common OAuth scenarios in mobile commerce apps, the second part is about the actual technical usage scenarios.

OAuth enables your mobile application to gain the permissions from account owners (who as well happen to be your mobile application users) to perform certain tasks on their behalf. Be it requesting the list of their Google contacts, requesting the information to access their Twitter and Facebook posts or do the actual update on their social walls.

List of open source mobile applications

Open source mobile application projects

At PopularOwl, we create tutorials and courses about open source technologies.

We would like to introduce you to the project we recently created called MobileGap. It’s the list of open source mobile application projects maintained by the community of mobile developers. The motto of this project is ‘don’t reinvent the wheel’

These mobile applications were made open source by their developers and in most cases are hosted on the community code repositories. The MobileGap web application is an open source project itself. It’s maintained in the Markdown format and we use metalsmith.io to build HTML pages.

Facebook SDK for mobile commerce applications

Facebook mobile SDK for iOS applications

Social integration use cases in mobile commerce apps

Extending on the subject of mcommerce and mobile SDK integrations this post will be about the value your mobile commerce application can receive from direct integration with social networks.

We will review integration options with the strongest social network out there – Facebook, who has a native SDK (software development kit) available for both iOS and Android mobile platforms.

First part of this post will examine the potential use cases and user flows in mobile commerce application and the second part will examine actual implementation code needed for integrating current version of Facebook SDK library into iOS mobile app (to be used on iPhone and iPad devices).

Payment methods in mobile commerce applications. What are the best options out there?

Adding Stripe iOS library to the mobile commerce application

Why is in app payment flow so important?

Payment process is a crucial user experience flow element in any mobile commerce application. Mcommerce application has to have an easy to navigate screens, short user registration process, appealing and attractive design but in the end of the day its the number of sold items what matters to the bottom line. And this cannot be achieved without a payment step.

The nature of native mobile application is very different from the web based app (as it runs on the remote mobile device which application developer cannot control). This requires a specific approach to handling information security and data flow as well as user experience on mobile device screens with limited number of pixels available. Payment steps in best scenarios have to be non intrusive and maybe even transparent for the end user (with the final confirmation required of course).

Because of this and the back-end complexity of the actual payment processing the best option for majority mobile commerce applications is to integrate already existing mobile payment library or bundle provided by reliable 3rd party payment gateway. Such libraries are designed with the mobile architecture in mind, in most cases they have nice and simple UX controls in place and only few click checkout experiences.

In our today’s post I’ll list most popular payment libraries available for mobile commerce applications built on Apple iOS mobile platform (iPhones, iPads) and will do a technical review for one such library which enables mobile applications to accept credit card payments directly in app.
