Several Red Hat engineers attended the JTC1/SC22/WG21 C++ Standards Committee meetings in November 2017. This post focuses on the sessions of SG1, the study group on parallelism and concurrency. SG1 had a full schedule as usual, with Executors, Futures, and deferred reclamation mechanisms (e.g., RCU) being major discussion topics. We also started to track the state of proposals and topics we will need to discuss in a publicly accessible bug tracker. I have argued in the past that SG1 should...

Today we're going to create a .NET Core 2.0 Web Application using the JBoss Developer Studio and the aCute plugin (C# application development). We'll deploy our application onto an OpenShift instance and continue to modify it while viewing the changes almost instantly. Although the initial setup will be quite involved, it will only need to be done once. You might imagine that the normal workflow for this would be: Make local changes. Commit + push them to version control. Either...

GraphQL is a query language for APIs. It provides a complete and understandable description of the data in your API and gives clients the power to ask for exactly what they need and nothing more. Send a GraphQL query to your API and get exactly what you need. These queries always return predictable results using GraphQL. It is fast and stable. Once you have opened the GraphQL explorer provided by GitHub, you'll notice that it will display a sample query...

GDB has evolved in the last several years to provide a Python API. This series of articles will look at how a user can program GDB with the API and will also take an in-depth look at several features of that API. But, before we begin, a small history lesson is needed and a look at just why an API was needed. Why an API? The humble debugger. We've all used one at some point in our careers, sometimes with...

Support for Java™ 9 Starting from Red Hat JBoss Developer Studio 11.1, Java™ 9 is now supported.

(Part 4)The GNU Toolchain is a collection of programming tools produced by the GNU Project. The tools are often packaged together due to their common use for developing software applications, operating systems, and low-level software for embedded systems. This blog is part of a regular series covering the latest changes and improvements in the components that make up this Toolchain. Apart from the announcement of new releases, however, the features described here are at the bleeding edge of software development...

llvm-toolset is a new software collection that packages together a number of the tools distributed by the LLVM project, including: LLVM tools and libraries, clang, clang-tools-extra, and lldb. Installing llvm-toolset For updated installation instructions, see How to install Clang/LLVM 6 on Red Hat Enterprise Linux. Clang/LLVM 5.x is packaged in as llvm-toolset-7, which is available in the rhel-7-server-devtools-rpms repo for RHEL 7. (If you don’t already have RHEL 7, Red Hat offers no-cost RHEL subscriptions for development use here.) You...

One of the new software collections we’ve introduced this fall is for Go, the programming language that aims to make it easy to build simple, reliable, and efficient software. Go is a compiled, statically typed language in the C/C++ tradition with garbage collection, concurrent programming support, and memory safety features. In go-toolset-7, we’re including everything you need to start programming in Go on Red Hat Enterprise Linux 7, in the familiar format of software collections. In this release, we’re shipping...

We know that containers in Openshift or Kubernetes don't persist data. Every time we start an application, it is started in a new container with an immutable Docker image. Hence, any persisted data in the file systems is lost when the container stops. Hence if an application or container is rebuilt or restarted than we can't view previous logs or if we are using containers with mysql or any other database then schema, tables, and all data will be lost...

The release of OpenShift Container Platform 3.6 brings support for vsphere cloud provider. This provides vsphere VMDK dynamic provisioning for persistent volumes for container workloads. The storage presented to vsphere virtual machines as a VMDK has ReadWriteOnce access mode. In the OCP 3.6 on vSphere reference architecture, much of this process is automated and can be implemented easily. Virtual Machine Disks or VMDKs exists in virtual machines. Configuring the OCP cluster for vsphere cloud provider support requires: Master Node Configuration...

Distributed Architectures are a lot like neural networks; all services that talk to each other need to share the I/O in and in a way that they can synchronize that information on the fly. The way the brain does is that each neuron that communicates with another has the other neuron fire back a neurotransmitter to synchronize and improve that communication in the future thus creating a pattern. While this behavior is almost identical to what is known as a...
