Create powerful blockchain queries with Hyperledger Composer
With the native, rich Query language in Hyperledger Composer, it's easy to perform complex and powerful queries on assets, transactions, and other resources. First, you model the query using Hyperledger Composer, and the query is deployed to the runtime Hyperledger Fabric. All that's left is to for you to consume the query by name in your application. You can also easily consume queries using REST APIs that are auto-generated by Hyperledger Composer. Without this capability, you'd have to construct ad hoc queries in your code and then labor to make sense of the results returned.

A developer's guide to complying with PCI DSS 3.2 Requirement 6
The Payment Card Industry Data Security Standard (PCI DSS) is a highly prescriptive technical standard, which is aimed at the protection of debit and credit card details, which is referred to within the payments industry as cardholder data. The objective of the standard is to prevent payment card fraud, by securing cardholder data within organizations that either accept card payments, or are involved in the handling of cardholder data. PCI DSS consists of 12 sections of requirements, and usually responsibility for compliance rests with IT infrastructure support. PCI DSS requirement 6 alone breaks down into 28 individual requirements, and sits squarely with software developers who are involved in the development of applications that process, store, and transmit cardholder data. This article aims to focus on all aspects of requirement 6. PCI compliance heavily revolves around IT services. IT focused compliance managers that are tasked with achieving compliance within organizations, often lack the required software developer knowledge and experience to help assure that the application development meets the arduous requirements of PCI DSS. Follow along to read a developer's perspective to complying with PCI DSS requirements.

Configure SoftLayer components for use with Account Defined Network
Learn how to provision and configure the necessary infrastructure components for SoftLayer's new Account Defined Network (ADN) feature. In this tutorial, we show you how to do this by calling REST-based APIs, and use CURL as the command-line utility from the Linux OS to call the REST-based API with a JSON payload. The JSON payload defines all the parameters that are required to create a particular component. We have done thorough testing and troubleshooting on the commands shown here to ensure their correctness. This tutorial can be particularly useful for users who want to automate their infrastructure setup process.
