  • Open Source Defies Conflicts of Interest: Red Hat Tells All

    Only two parts of the guidelines state any sort of limit on company associates, she clarified. The first is that projects use an Open Source Initiative-approved license. The second is that if an associate is asked to sign a third-party contributor agreement, they should check with Red Hat’s legal team.

  • ANZ moves internet banking to Red Hat OpenShift

    The Australia and New Zealand Banking Corporation (ANZ) in October last year turned to Red Hat for help to bring its internet banking proof of concept to life.

    The bank wanted to modernise its internet banking platform that had passed its end of life and required extended support for some years. Deciding on a Red Hat OpenShift platform, tech area lead for ANZ's digital arm Raghavendra Bhat said the bank wanted to not constrain itself to a cloud-only solution.

    ANZ has now migrated 30% of its traffic to the platform and within the first hour of go-live, it processed around AU$2.9 billion worth of payments.

    Speaking with media on Wednesday, Bhat said the bank's expectation is to complete about 80% of the traffic transition onto the new platform by November, with complete transition by March. He said there has been no "cookie-cutter approach" for how it has lifted and shifted the old system onto the new one.

  • Juggling Ansible, OpenShift and K8s? This is for you: Red Hat couples automation to cluster management

    Red Hat is integrating its Ansible automation platform and Advanced Cluster Management for Kubernetes.

    “We've known people use Ansible and OpenShift and Kubernetes together for years,” Red Hat senior manager Richard Henshall told The Register. “But here we get a bona fide integration between the two.” Typical uses would be to automate deploying system updates, configuring load balancers, or scaling server resources.

    The integration is in technical preview. “We’ve got the initial plumbing working, so it’s exposed through Advanced Cluster Management (ACM),” said Henshall, referring to the company’s tool for controlling OpenShift clusters and applications.

  • Why it's important to keep the cloud open | Opensource.com

    There's a famous sticker featured on many laptop lids; it goes something like this: "the 'cloud' is just somebody else's computer."

    There's a lot of truth to that sentiment, but it's not exactly technically accurate. In fact, cloud computing isn't just somebody else's computer; it's somebody else's hundreds and thousands of computers.

    Years ago, "the cloud" did indeed just refer to the simplified graphic in a flowchart, so the illustrator didn't have to try to accurately depict the multiple networks that comprise the World Wide Web. Now, however, the cloud isn't just describing traffic or small-time remote file storage offers. The cloud of today is a platform of interconnected computational nodes working together to keep containerized Linux images, each running a distinct service (or "microservice" in developer lingo), functioning as applications distributed over the whole world.

  • IBM integrates Linux One with R3 Corda Enterprise

    It’s an exciting time for IBM LinuxONE. Over the past several months, we’ve been doubling down on new hardware, Red Hat OpenShift and new Cloud Paks for LinuxONE, and new confidential computing capabilities.

    More than ever, our clients of all sizes looking to win in the era of hybrid cloud are focused on key areas: resiliency, performance demands, security, flexibility and modernization.

    Other areas of growth for LinuxONE are emerging workloads and industries like blockchain and digital asset custody. While the importance of safeguarding business and customer data is well known, the nature of blockchain use cases often include the initiation, transfer and custody of financial assets for your business and your customers—which further increases the importance of building applications with security and privacy first.

  • Persistent storage in action: Understanding Red Hat OpenShift's persistent volume framework - Red Hat Developer

    Red Hat OpenShift is an enterprise-ready Kubernetes platform that provides a number of different models you can use to deploy an application. OpenShift 4.x uses Operators to deploy Kubernetes-native applications. It also supports Helm and traditional template-based deployments. Whatever deployment method you choose, it will be deployed as a wrapper to one or more existing OpenShift resources. Examples include BuildConfig, DeploymentConfig, and ImageStream.

    In this article, I introduce you to OpenShift’s Kubernetes-based persistent volume framework for persistent cluster storage. You will learn how to use OpenShift’s PersistentVolume (PV) and PersistentVolumeClaim (PVC) objects to provision and request storage resources.

  • How to use the Linux kernel's Integrity Measurement Architecture

    The kernel integrity sub-system can be used to detect if a file has been altered (accidently or maliciously), both remotely and/or locally. It does that by appraising a file's measurement (its hash value) against a "good" value stored previously as an extended attribute (on file systems which support extended attributes like ext3, ext4. etc.). Similar, but complementary, mechanisms are provided by other security technologies like SELinux which depending on policy can attempt to protect file integrity.

    The Linux IMA (Integrity Measurement Architecture) subsystem introduces hooks within the Linux kernel to support creating and collecting hashes of files when opened, before their contents are accessed for read or execute. The IMA measurement subsystem was added in linux-2.6.30 and is supported by Red Hat Enterprise Linux 8.

    The kernel integrity subsystem consists of two major components. The Integrity Measurement Architecture (IMA) is responsible for collecting file hashes, placing them in kernel memory (where userland applications cannot access/modify it) and allows local and remote parties to verify the measured values. The Extended Verification Module (EVM) detects offline tampering (this could help mitigate evil-maid attacks) of the security extended attributes.

    IMA maintains a runtime measurement list and, if anchored in a hardware Trusted Platform Module(TPM), an aggregate integrity value over this list. The benefit of anchoring the aggregate integrity value in the TPM is that the measurement list is difficult to compromise by a software attack, without it being detectable. Hence, on a trusted boot system, IMA-measurement can be used to attest to the system's runtime integrity.

  • Thoughts of Dev: One piece of advice to a new developer – IBM Developer

    We all have to start someplace in our careers and as a developer, you have a LOT of options and decisions to make. From your first job and industry, programming language to learn, training, soft skills and more. The choices are endless and each right decision (and sometimes wrong decision) helps bring you to where you are today in your career. Looking back, if you could give an important piece of advice to a junior developer, what would you tell them?

  • How Red Hat celebrated Hispanic Heritage month

    We’ve always maintained that a diverse and inclusive organization thrives when people from different backgrounds feel comfortable being their full self when they’re at work. This includes sharing and celebrating holidays and traditions with colleagues that are important to their culture or heritage. At Red Hat, Diversity and Inclusion (D&I) communities are a rich source for associates to have new experiences and learn from others with different backgrounds. Our D&I communities are global, associate-led groups focused on fostering diversity and inclusion, knowledge sharing, learning and development, and relationship building.

    Unidos, our Latinx and Hispanic D&I community, recently led its first formal recognition of Hispanic Heritage Month. The team organized virtual events for associates including a live cooking session of traditional hispanic cuisine (arepas con carne or a patacon/jibaritos sandwich anyone?) and a panel discussion featuring Red Hatters from Unidos discussing different aspects of Latinx and Hispanic culture including language, traditional family dynamics and the experience of being an immigrant.

  • Multi-stack deployments for the edge with Red Hat OpenStack Platform 16.1

    In past releases, Red Hat OpenStack Platform director has used a single Heat stack for the overcloud deployment. With the Train release, it’s now possible to use multiple stacks for a single cloud deployment. Multiple stacks is advantageous to edge deployments as it allows for each distributed edge site to be managed and scaled independently, minimizing operational complexity. First, let’s review the concept of a "stack" in director, as the term can often have overloaded meanings in software engineering.

  • Build custom Ansible modules using Python's Pexpect

    When developing automation you may be faced with challenges that are simply too complicated or tedious to accomplish with Ansible alone. There may even be cases where you are told that "it can’t be automated." However, when you combine the abilities of Ansible and custom Python using the Pexpect module, then you are able to automate practically anything you can do on the command line. In this post we will discuss the basics of creating a custom Ansible module in Python.

    [...]

    If these tools also provided a non-interactive mode or config/script input we would not need to do this. To overcome this situation we need to use Python with Pexpect. The native Ansible expect module provides a simple interface to this functionality and should be evaluated before writing a custom module. However, when you need more complex interactions, want specific data returned or want to provide a re-usable and simpler interface to an underlying program for others to consume, then custom development is warranted.

  • Node.js 15 release: Updated handling of rejections, npm 7, N-API Version 7, and more – IBM Developer

    Users can plan for a new release every April and October, with the latest even-numbered release (14.x, in this instance) being promoted to LTS in October. Since the 15.x release is an odd-numbered release, it won’t be promoted to LTS. The predictable timetable for quality releases has increased adoption of the next LTS release over time. In general we recommend that only LTS releases be used for production deployments.

    Today, the Node.js community is releasing Node.js 15 with new features that are important to Node.js users and customers. While it won’t be promoted to long-term support (LTS), we need our customers and the greater ecosystem to try it out and give us feedback to help pave the way for the Node.js 16 release.

  • Introducing Red Hat's Open Source Participation Guidelines

    When your whole business revolves around open source, community participation, and upstream-first development, it's a reasonable assumption that you’re going to get asked about how all of that works.

    And it’s not like we’re secretive about it. My colleagues in the Open Source Program Office have posted guides, FAQs, and white papers. We’ve had then Red Hat CEO Jim Whitehurst do TED talks. He even wrote a book! Yet still, there are a lot of individuals and organizations who will come up to us and ask us how Red Hat makes this all work.

  • How open source leads to open doors [Ed: Well, it’s a good thing they don’t know what racist IBM did at the beginning]

    In today’s climate, racial equality and equity is top of mind. The tech industry has a renewed focus on giving girls in underrepresented communities access and exposure to STEM, particularly in the pre-teen and teen years that are critical to keeping girls interested in STEM subjects. Giving adolescent girls access to skills like coding and introducing them to open source prepares them for college and career and opens new doors and opportunities

    [...]

    As part of our continuing social justice efforts and commitment to racially equality, IBM is awarding our next open source community grant to Black Girls CODE. Launched in 2011, Black Girls CODE (BGC), with 15 chapter cities in the U.S. and abroad, is a transformative global movement that hosts technology-focused weekend workshops, hackathons, summer camps, and many other enrichment opportunities for more than 20,000 low-income, Black girls — or as they call themselves, Tech Divas.

    Additionally, IBM has partnered with Black Girls CODE as a National Alumnae Ambassador Program Sponsor to help cultivate the next generation of STEM developers. This partnership allows Black Girls CODE and their Tech Divas to participate in two initial opportunities with IBM — one with IBM’s Call for Code for Racial Justice program and another with IBM offerings for workshops on STEM topics like quantum, artificial intelligence, and hybrid cloud.

  • After Years of Promise and Hype, Is AI Once More Failing to Deliver? [Ed: IBM still leaning on mindless hype wave called after its racist founder]

    The June 13 issue of The Economist included an in-depth look at the limits of AI, with seven articles on the subject.  “There is no question that AI - or, to be precise, machine learning, one of its sub-fields - has made much progress,” notes The Economist in the issue’s overview article.  “Computers have become dramatically better at many things they previously struggled with…  Yet lately doubts have been creeping in about whether today’s AI technology is really as world-changing as it seems.  It is running up against limits of one kind or another, and has failed to deliver on some of its proponents’ more grandiose promises.”

    Transformative technologies, - remember the dot-com bubble, - are prone to hype cycles, when all the excitement and publicity accompanying their early achievements often lead to inflated expectations, followed by disillusionment if the technology fails to deliver.  But AI is in a class by itself, as the notion of machines achieving or surpassing human levels of intelligence has led to feelings of both wonder and fear over the past several decades.

    The article reminds us that AI has gone through two such major hype cycles since the field began in the mid-1950s.  Early achievements, - like beating humans at checkers and proving logic theorems, - led researchers to conclude that machines would achieve human-level intelligence within a couple of decades.  This early optimism collapsed leading to the first so-called AI winter from 1974-1980.  The field was revived in the 1980s with the advent of commercial expert systems and Japan’s Fifth Generation project, but it didn’t last long, leading to the second AI winter from 1987-1993.

  • Secure NTP with NTS

    Many computers use the Network Time Protocol (NTP) to synchronize their system clocks over the internet. NTP is one of the few unsecured internet protocols still in common use. An attacker that can observe network traffic between a client and server can feed the client with bogus data and, depending on the client’s implementation and configuration, force it to set its system clock to any time and date. Some programs and services might not work if the client’s system clock is not accurate. For example, a web browser will not work correctly if the web servers’ certificates appear to be expired according to the client’s system clock. Use Network Time Security (NTS) to secure NTP. Fedora 331 is the first Fedora release to support NTS. NTS is a new authentication mechanism for NTP. It enables clients to verify that the packets they receive from the server have not been modified while in transit. The only thing an attacker can do when NTS is enabled is drop or delay packets. See RFC8915 for further details about NTS. NTP can be secured well with symmetric keys. Unfortunately, the server has to have a different key for each client and the keys have to be securely distributed. That might be practical with a private server on a local network, but it does not scale to a public server with millions of clients. NTS includes a Key Establishment (NTS-KE) protocol that automatically creates the encryption keys used between the server and its clients. It uses Transport Layer Security (TLS) on TCP port 4460. It is designed to scale to very large numbers of clients with a minimal impact on accuracy. The server does not need to keep any client-specific state. It provides clients with cookies, which are encrypted and contain the keys needed to authenticate the NTP packets. Privacy is one of the goals of NTS. The client gets a new cookie with each server response, so it doesn’t have to reuse cookies. This prevents passive observers from tracking clients migrating between networks.

Intel added integer mode scaling to their Windows graphics driver back in 2019 to provide better clarity when upscaling games (particularly pixel art type content) and other software. The Linux patches materialized in September 2019 for nearest-neighbor integer mode scaling and then seemingly forgotten about. The capability works with Gen11 / Ice Lake and newer.

  • Linux Support for Variable Refresh Rates On Gen12+ Intel GPUs Is On The Way - LinuxReviews

    Intel developer Manasi Navare has submitted a series of patches for the Linux kernel that brings support for variable refresh rates on Intel's latest graphics chips to the Linux kernels i915 driver. The feature is only enabled on Tiger Lake, Sapphire Rapids and newer Intel graphics chips. [...] You do not need a special "Freesync" monitor to use adaptive vertical synchronization, Freesync is just a marketing term used by AMD. The DisplayPort specification has included variable refresh rate (VRR) as an option feature since DP 1.4 and there are many monitors with support for it that are not marketed as "Freesync" or "gaming" monitors. Monitors that are marketed as "Freesync" support the standard DisplayPort VRR protocol so you don't need to use a AMD graphics card to get the benefits of a Freesync monitor. You will soon be able to use one of the very latest Intel CPU's with integrated graphics or one of Intel's upcoming dedicated graphics cards with Freesync monitors on Linux.

  • Salsa updated to GitLab 13.5

    Today, GitLab released the version 13.5 with several new features. Also Salsa got some changes applied to it. [...] It's been way over two years since we started to use Google Compute Engine (GCE) for Salsa. Since then, all the jobs running on the shared runners run within a n1-standard-1 instance, providing a fresh set of one vCPU and 3.75GB of RAM for each and every build. GCE supports several new instance types, featuring better and faster CPUs, including current AMD EPICs. However, as it turns out, GCE does not support any single vCPU instances for any of those types. So jobs in the future will use n2d-standard-2 for the time being, provinding two vCPUs and 8GB of RAM..
