  • What's new in Red Hat Enterprise Linux 8.3? Enhanced container tools, more system roles and new cloud admin tools just for starters

    Red Hat Enterprise Linux (RHEL) 8.3 will be available in the coming weeks. In this post we'll take a look at some of the highlights and important new features that are planned for RHEL subscribers.

    A RHEL release has many constituencies. RHEL has to meet the needs of system administrators who crave system stability and predictability, and developers who want flexibility and new language and software choices. With new system roles, a major RHEL container tools update, cloud administration updates and more, RHEL 8.3 delivers for those who depend on enterprise open source to run today's businesses.

    The third update since RHEL 8's release in early 2019, RHEL 8.3 continues the six-month cadence of minor releases. By offering a predictable, time-based release cycle we help drive new features in a timely fashion without compromising the reliability of RHEL that our users and customers depend on.

  • Collect JDK Flight Recorder events at runtime with JMC Agent - Red Hat Developer

    JDK Flight Recorder, or JFR, is an event-based production environment profiler available from OpenJDK 8u272 forward. Being a HotSpot-native feature, JDK Flight Recorder performs with extremely low overhead in terms of how it uses both space and time.

    While JDK Flight Recorder collects basic Java runtime information by default, it is also possible to use JFR’s Event API to collect custom events. Developers who want to collect application-level events must actively define and instantiate them in their application source code.

    In this article, we’ll show you how to use JMC Agent and the JMC Agent Plugin to instrument your application classes with event-emitting code. When you use JMC Agent with the JDK Flight Recorder Event API, you do not need to shut down the JVM and recompile the application code.

  • New custom metrics and air gapped installation in Red Hat 3scale API Management 2.9 - Red Hat Developer

Among other features, we have updated the 3scale API Management and Gateway Operators.

    This article introduces the Red Hat 3scale API Management 2.9 release highlights, including air-gapped installation for 3scale on Red Hat OpenShift and new APIcast policies for custom metrics and upstream mutual Transport Layer Security (TLS).

RHEL 8.3 updates target digital transformation

  • RHEL 8.3 updates target digital transformation

    With an eye toward easing digital transformation projects, the latest version of Red Hat Enterprise Linux includes improved container tools, new security profiles and the addition of several System Roles, including ones for kernel settings, SAP HANA and NetWeaver.

    Red Hat also improved RHEL performance, adding updates to Tuned, which is a set of pre-configured profiles. Tuned allows IT shops to take better advantage of Red Hat's multi-architecture, enabling software to run faster across a number of different hardware architectures. Also, Red Hat Insights continues to remain available by default for RHEL systems. As part of version 8.3, Red Hat added administrator views specifically for SAP HANA deployments.

    System Roles makes both common and complex RHEL configurations more consistent and accessible to a wider range of IT skillsets in large organizations.

  • RHEL 8.3 Released With TSX Disabled By Default To Avoid Mitigation Overhead

    Red Hat Enterprise Linux 8.3 is out today as the latest release of the RHEL8 platform.

    The latest stable release of Red Hat Enterprise Linux 8, RHEL 8.3, is focused on expanded Red Hat System Roles support, updates to Tuned, new SCAP profiles, updated Application Streams, and other enterprise-minded stability enhancements. Some specific changes to note with Red Hat Enterprise Linux 8.3 include:

    - RHEL 8.3 is now disabling Intel Transactional Synchronization Extensions (TSX) by default. Disabling of TSX by default is done in the name of security and to remove the performance penalty of having TSX Asynchronous Abort mitigations for Xeon Cascade Lake processors. TSX can be enabled with the "tsx=on" kernel parameter.

    - New module streams for Ruby 2.7, Nginx 1.18, Perl 5.30, and Node.js 14. The streams for Python 3.8, PHP 7.4, and HTTPD 2.4.

13 Best Free and Open Source Python Microframeworks

One of the types of software that’s important for a web developer is the web framework. A framework “is a code library that makes a developer’s life easier when building reliable, scalable, and maintainable web applications” by providing reusable code or extensions for common operations. By saving development time, developers can concentrate on application logic rather than mundane elements. A web framework offers the developer a choice about how to solve a specific problem. By using a framework, a developer lets the framework control portions of their application. While it’s perfectly possible to code a web application without using a framework, it’s more practical to use one. Read more

Valve Backs Zink Work

  • Mike Blumenkrantz: Don’t Call It A Comeback

    I guess I never left, really, since I’ve been vicariously living the life of someone who still writes zink patches through reviewing and discussing some great community efforts that are ongoing. But now I’m back living that life of someone who writes zink patches. Valve has generously agreed to sponsor my work on graphics-related projects. For the time being, that work happens to be zink.

  • Valve Now Funding Blumenkrantz - Zink OpenGL-On-Vulkan To Continue

    Longtime open-source developer Mike Blumenkrantz who has been an Enlightenment developer for many years and was working for Samsung's Open-Source Group prior to its demise jumped into the open-source Linux graphics world this year. While being unemployed he began hacking on the Zink Gallium3D code that allows generic OpenGL acceleration over the Vulkan API. He quickly got the code to the point of OpenGL 4.6 support and quite compelling performance compared to where Zink was at earlier this year. Now it turns out he will continue with his Linux graphics adventures thanks to funding from Valve. Mike Blumenkrantz shared today that Valve is going to be sponsoring his graphics-related work moving forward. At least for now, that Linux graphics work is still on the matter of Zink.
