Red Hat Software Collections 3.6 and Red Hat Developer Toolset 10 for Red Hat Enterprise Linux (RHEL) are now available as beta releases. An alternative to the default RHEL toolset, Software Collections provides a differentiated and eclectic mix of tools that developers can use on a desktop or in production.

If you’re like me—a developer who works with customers who rely on the tried-and-true Red Hat Enterprise Linux (RHEL), works with containerized applications, and also prefers to work with Fedora Linux as their desktop operating system—you’re excited by the announcement of the Universal Base Images (UBI). This article shows how UBI actually works, by building the container image for a simple PHP application.
With UBI, you can build and redistribute container images based on Red Hat Enterprise Linux without requiring a Red Hat subscription. Users of UBI-based container images do not need Red Hat subscriptions. No more extra work creating CentOS-based container images for your community projects or for your customers that prefer self-support.
I tested all these steps on my personal Fedora 29 system, and they should work on any Linux distribution. I am also a big fan of the new container tools such as Podman, which should be available to your favorite Linux distribution. If you are working on a Windows or MacOS system, you can replace the Podman commands with Docker.

On the heels of our recently announcement, General Availability of Clang/LLVM 6.0, Go 1.10, and Rust 1.29, I want to share how we’ll be supporting them going forward. Previously, these packages had been in “Technology Preview” status, which means that they were provided for “you to test functionality and provide feedback during the development process”, and were “not fully supported under Red Hat Subscription Level Agreements, may not be functionally complete, and are not intended for production use”.
So now that we’ve promoted them to fully supported status, what does that mean? In the simplest terms, General Availability (GA) means that these packages have officially entered the “Full Support Phase” of their lifecycle:

A newer version of this article is available: How to install GCC 8 and Clang/LLVM 6 on Red Hat Enterprise Linux 7.
If you are developing with C/C++, Clang tools and newer versions of GCC can be quite helpful for checking your code and giving you better warnings and error messages to help avoid bugs. The newer compilers have better optimizations and code generation.
You can easily install the latest-supported Clang and GCC compilers for C, C++, Objective-C, and FORTRAN using
yum on Red Hat Enterprise Linux. These compilers are available as software collections that are typically updated twice a year. The May 2018 update included Clang/LLVM 5 and GCC 7.3, as well as Go and Rust.
If you want your default
gcc to always be GCC 7, or you want
clang to always be in your path, this article shows how to permanently enable a software collection by adding it to the profile (dot files) for your user account. A number of common questions about software collections are also answered.

Red Hat Enterprise Linux continues to deliver the best possible experience for enterprise system administrators and developers, as well as provide a solid foundation for moving workloads into both public and private clouds. One of the ways to enable such ubiquity is Red Hat’s multi-architecture initiative, which focuses on bringing Red Hat’s software portfolio to different hardware architectures.
Last week, Red Hat Enterprise Linux 7.5 went live. It brought forward several improvements relevant to developers and system administrators such as advanced GUI system management via the Cockpit console, which should help new Linux administrators, developers, and Windows users to perform expert tasks without having to get into the command line.
This release also marks a new milestone for Red Hat Enterprise Linux: all supported architectures are now simultaneously enabled. The list of supported architectures includes x86_64, PowerPC Big Endian and Little Endian, s390x, and the more recently introduced 64-bit Arm and IBM POWER9 architectures.

APIs are critical to automation, integration and developing cloud-native applications, and it’s vital they can be scaled to meet the demands of your user-base. In this article, we’ll create a database-backed REST API based on the Python Falcon framework using Red Hat Software Collections (RHSCL), test how it performs, and scale-out in response to a growing user-base.

JBoss Tools 4.5.1 and Red Hat JBoss Developer Studio 11.1 for Eclipse Oxygen.1A are here waiting for you. Check it out!

One of the new software collections we’ve introduced this fall is for Rust, the programming language that aims for memory and thread safety without compromising performance. Dangling pointers and data races are caught at compile time, while still optimizing to fast native code without a language runtime!
In rust-toolset-7, we’re including everything you need to start programming in Rust on Red Hat Enterprise Linux 7, in the familiar format of software collections. In this release, we’re shipping Rust 1.20 and its matching Cargo 0.21 – both as Tech Preview. (NOTE: The “-7” in our toolset name is to sync with the other collections now being released, devtoolset-7, go-toolset-7, and llvm-toolset-7.)
