Deploy a sample application to the IBM Blockchain Platform Starter Plan

Step by step, see how to create a network on the IBM Blockchain
Platform, install a smart contract (chaincode), and run a sample application
to invoke it. You’ll also see how to populate the shared ledger and
communicate with it by making calls from a local client application to query
and update the ledger.

Unit 23: Java in the cloud

Learn the structure, syntax, and programming paradigm of the Java
platform and language. Start by mastering the essentials of object-oriented
programming on the Java platform, and progress incrementally to the
more-sophisticated syntax and libraries that you need to develop complex,
real-world Java applications.

On demand data in Python, Part 3: Coroutines and asyncio

Much of the data in modern big data applications comes from the web or
databases. You need to write code to process this at scale, but you don’t want
everything to grind to a halt in the process. Python 3 introduced a system for
cooperative multitasking, which alleviates this problem, using asynchronous
coroutines. Asynchronous coroutines build on similar concepts to generators.
They are objects created from special functions which can be suspended and
resumed. They make it possible to break down complex and inefficient
processing into simple tasks that cooperate to maximize trade-offs between CPU
and input/output. Learn these core techniques following a simple sequence of
examples.

Blockchain basics: Hyperledger Fabric and Hyperledger Composer

The names are similar, but knowing the difference
is key to getting started with blockchain development. Hint: One is
a cool development tool, and the other is the powerful engine of business blockchain
networks. Learn how to put them both to work.

Support for responding to RDP ELS with IBM AIX FC/FCoE device driver stack

The Read Diagnostic Parameters (RDP) Extended Link Service (ELS) is an enhanced
capability that requests the Fiber Channel (FC) Host Bus Adapter (HBA) port to return the
diagnostic information. In large data centers, this data is useful to identify the faulty
ports quickly.

On demand data in Python, Part 2: The magic of itertools

Python’s motto has always been “Batteries included,” to highlight its
extensive standard library. There are many well-kept secrets among the standard modules, including itertools, which is less well known in part because iterators and generators are less well known. This is a shame because the routines in itertools and related modules such as functools and operators can save developers many hours in developing big data operators. Learn by copious examples how to use itertools to address the most common MapReduce-style data science tasks.
