  • Red Hat Fills a Gap with OpenShift Data Science [Ed: "Red Hat is a sponsor of The New Stack," it says at the bottom and this site does puff pieces about it sponsor. This is corruption of journalism by IBM, just like Microsoft.]

    Following its initial launch earlier this year, Red Hat has released Red Hat OpenShift Data Science as a “field trial”. The managed cloud service provides enterprises with an environment tailored for artificial intelligence and machine learning (AI/ML) on Red Hat OpenShift.

  • Technically Speaking (S1E10): Building practical self-healing IT - Invidious

    When IT operations fail, it would be great if our infrastructure could use automation and machine learning to simply fix itself. Self-healing infrastructure is a lofty goal, but how practical is it? In this episode, Red Hat CTO Chris Wright is joined by Mike Dobozy to talk about building an event driven automation solution that lays the foundation for more complex self-healing infrastructure. With artificial intelligence and machine learning, DevOps has evolved, and adding self-healing capabilities to the organization's existing infrastructure can have immediate benefits. But once we start to look at more complicated problems that require more data and more timing-based or complex event processing, how do we cut through the noise and make it simpler to solve problems? Join us for another Technically Speaking with Chris Wright to learn more about how event-driven automation is being used to build self-healing solutions and is helping us realize a future with truly closed-loop automation and autonomic systems.

  • IT leadership: 9 powerful ways to coach your rising stars

    Today's IT leaders and managers be fluent in an ever-growing list of technology fundamentals, plus think and operate as part of the business, creating connections and building trust with key stakeholders. “IT leaders need to become even more facile with the language of business, and they have to go deeper than that to strengthen their empathy muscle — recognizing how [technology] impacts a stakeholder, recognizing the pain around it, and communicating that they recognize it,” says Elizabeth Freedman, head of consulting at executive coaching and assessment firm Bates.

    Unfortunately, the next generation of tech leaders may lack some of the related skills — and it’s not necessarily their own fault. They’ve been busy during the past two years, to say the least. “That next level of leader is just not ready to lead in [these] ways,” Freedman says. “Their heads are down.”

    One-on-one coaching is critical to grooming more fully-formed IT leaders.
    Rising IT professionals need clear direction, correction, and encouragement to mature into the multi-faceted business leaders that their organizations require. While training and classes may help, one-on-one coaching is critical to grooming more fully-formed IT leaders.

  • Introducing CentOS Stream 9

    CentOS Stream is a continuous-delivery distribution providing each point-release of Red Hat Enterprise Linux (RHEL). Before a package is formally introduced to CentOS Stream, it undergoes a battery of tests and checks—both automated and manual—to ensure it meets the stringent standards for inclusion in RHEL. Updates posted to Stream are identical to those posted to the unreleased minor version of RHEL. The aim? For CentOS Stream to be as fundamentally stable as RHEL itself.

    To achieve this stability, each major release of Stream starts from a stable release of Fedora Linux—In CentOS Stream 9, this begins with Fedora 34, which is the same code base from which RHEL 9 is built. As updated packages pass testing and meet standards for stability, they are pushed into CentOS Stream as well as the nightly build of RHEL. What CentOS Stream looks like now is what RHEL will look like in the near future.

  • Fedora 36 May Support FS-VERITY Integrity/Authenticity Verification For RPMs - Phoronix

    Fedora 36 may support using the Linux kernel's fs-verity code for allowing some interesting integrity and authenticity use-cases around RPM packages.

    The Linux kernel's fs-verity module provides authenticity protection for read-only files for transparently verifying their integrity and authenticity when those files are on supported file-systems. FS-VERITY allows bulding a Merkle tree for a given file and that to persist with the file and later on the file can then be verified against that Merkle tree. This can allow for detecting corrupted files whether accidental or intentional of malicious nature, auditing of files, and other similar security use-cases.

  • Introduction to the Node.js reference architecture, Part 6: Choosing web frameworks

    One of the key choices you make when building an enterprise Node.js application is the web framework that will serve as its foundation. As part of our Node.js reference architecture effort, we've pulled together many internal Red Hat and IBM teams to discuss the web frameworks they've had success with. From our meetings, we've learned that most of the developers we spoke to are still happy with Express.js. This web framework has long been considered the default for Node.js, and it holds that place in our reference architecture as well.

    However, Express.js is considered to be in maintenance mode. Thus, as part of the process of developing the reference architecture, we analyzed some data on web framework usage to try to get an idea of what might come next. In this article, you'll learn why Express.js is still a good fit for many Node.js developers and what the future could hold.

  • Patches welcome! How to contribute upstream to glibc

    By the time Red Hat customers run one of our products, it already has had a long history of development, testing, review, and other assorted refinements, both internally and across its many related upstream projects.

  • Anonymize data in real time with KEDA and Rook | Red Hat Developer

    Data privacy and data protection have become increasingly important globally. More and more jurisdictions have passed data privacy protection laws to regulate operators that process, transfer, and store data. Data pseudonymization and anonymization are two common practices that the IT industry turns to in order to comply with such laws.

    In this article, you'll learn about an open source cloud-native solution architecture we developed that allows managed data service providers to anonymize data automatically and in real time.

  • What is Ansible Automation Hub and why should you use it?

    Many Ansible users know about Ansible Galaxy—the Ansible project’s community repository for sharing Ansible content. While Ansible Galaxy is great for testing the latest and greatest developer content, it’s difficult to know which content is supported, and which content is people just uploading stuff. In a lot of ways, it’s like an app store with no rules.

    This is where Ansible Automation Hub comes in.

  • OpenShift Security Hardening for the healthcare industry

    In all industries, data lies at the heart of an organization, and data needs stringent, consistent and restricted access controls for risk reduction and protection against cybersecurity threats.

    It’s important to secure all sensitive data, of course, but extra care must be taken to ensure that personally identifiable information (PII) and personal health information (PHI) are properly protected. At the same time, that information also has to be available for use by authorized people and applications.

    There are a number of different strategies healthcare organizations can use to avoid data leaks. Here we present a prioritized list of measures for hardening Red Hat OpenShift using information from the OpenShift Security Guidelines and other sources.

SJVN: Red Hat's CentOS Stream 9 Linux arrives

  • Red Hat's CentOS Stream 9 Linux arrives

    Almost a year ago to the day, Red Hat changed CentOS from being a Red Hat Enterprise Linux (RHEL) clone to being a developmental rolling Linux distribution, CentOS Stream. Many users weren't happy. As a result, several replacement CentOS/RHEL clones, such as AlmaLinux and Rocky Linux, got their start. But, Red Hat continued with its plans to use CentOS to foreshadow the next edition of RHEL. Now, the new CentOS project is showing off it's latest and greatest in its first totally new release: CentOS 9.

CentOS Stream 9 is Now Generally Available

  • CentOS Stream 9 is Now Generally Available

    The release of CentOS Stream 9 has been carried out before CentOS Linux 8 expires at the end of this year.

    CentOS Stream saw the light of day in 2019 and fundamentally changed the work on the distribution. At the end of 2020, the announcement that Red Hat will shift its focus from CentOS Linux to CentOS Stream caused heated discussions.

    As you can imagine, many users were not satisfied with this decision. As a result, some replacement CentOS clones such as AlmaLinux and Rocky Linux soon came into play, which are now also generally available.

    Now the new CentOS project is showing off the latest and greatest in the first all-new release of CentOS Stream 9.

  • Statistics Module in Python

    If you’re in the research world, statistics is of paramount importance! And Python offers many a module for statistics, but the one that we’ll be talking about today is called the statistics module. It’s a simple module, not really for advanced statistics but for those who just need a simple and quick computation. In this tutorial, we’ll be reviewing the statistics module in Python.

  • Emulate the Do-While Loop in Python

    Most of the standard programming languages have three types of loops to iterate some statement multiple times. These are the while loop, for loop, and the do-while loop. The while and for loop are available in Python but Python has no do-while loop. The do-while loop can be implemented by using another loop. In the do-while loop, the condition is tested after inserting the loop. So, the statements of the do-loop execute at least once even if the condition may not be matched. The ways of emulating the do-while loop in Python have been shown in this tutorial.

  • [Old] “The Canary in the Coal Mine…” A cautionary tale from the decline of SourceForge

    This article tells the cautionary tale of the downfall of Allura/SourceForge. We identified both internal and external causes, both social and technical in nature. We also found evidence of sociotechnical and architectural problems in project archives. Project and community health metrics could have been used to predict and understand the downfall by tracking its early manifestations. The team reported to be aware of the technical debt in the project, yet this was insufficient to maintain the health of the project. Community managers should also measure and manage the mutual impacts of technical and social debt. Furthermore, our analysis suggests that a combination of managerial and technical flaws doomed this project: architectural flaws, power-distance, and measurable management mishaps eventually led to the forge's demise. Practitioners and maintainers of other software projects can benefit from this cautionary tale, for example, as indications of what not to do, in the scope of their community and architecture management infrastructure.

  • Dirk Eddelbuettel: RcppArmadillo 0.11.1.1.0 on CRAN: Updates

    Armadillo is a powerful and expressive C++ template library for linear algebra and scientific computing. It aims towards a good balance between speed and ease of use, has syntax deliberately close to Matlab and is useful for algorithm development directly in C++, or quick conversion of research code into production environments. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 978 other packages on CRAN, downloaded over 24 million times (per the partial logs from the cloud mirrors of CRAN), and the CSDA paper (preprint / vignette) by Conrad and myself has been cited 469 times according to Google Scholar. This release brings a first new upstream fix in the new release series 11.*. In particular, treatment of ill-conditioned matrices is further strengthened. We once again tested this very rigorously via three different RC releases each of which got a full reverse-dependencies run (for which results are always logged here). A minor issue with old g++ compilers was found once 11.1.0 was tagged to this upstream release is now 11.1.1. Also fixed is an OpenMP setup issue where Justin Silverman noticed that we did not propagate the -fopenmp setting correctly.

  • Reversed Linked List (C++)

    When you reverse a linked list, the link path is reversed, and the head becomes the tail, and the tail becomes the head. By swapping the positions of the nodes, we can understand this quickly. In this swapping, we just change the positions of the nodes from left to right or vice-versa.

  • Gets Function in C

    Bound-checking is therefore not accomplished by the gets() method. It would not examine if the input data integrates inside the character array’s holding limit of bytes. A buffer overflow can occur when an entry exceeds the array limit. Through fgets, this restriction of the gets() method could be eliminated. The gets() method produces a string if it occurs. It reverts NULL if it starts to fail. It displays the EOF indicator on a string if an end-of-file situation generates the error. If another error triggers the failure, the error parameter is displayed on the string.

  • Impact Analysis for UTF-8 in the RIPE Database

    The RIPE Database contains the names and addresses of organisations as well as administrative and technical contacts for resources and routing in the RIPE region. The Database currently supports the Latin-1 (ISO-8859-1) character set, which can represent most characters in western European languages. However it cannot fully support characters used in other languages and alphabets that are commonly used in the RIPE service region and beyond. Currently, any unsupported characters must be transliterated into Latin-1 (or even ASCII in some cases, which is a subset of Latin-1), potentially corrupting the meaning. Switching the RIPE Database from Latin-1 to UTF-8 allows names and addresses to be properly represented for querying and display.

  • Kubernetes 1.24: Volume Populators Graduate to Beta | Kubernetes

    The volume populators feature is now two releases old and entering beta! The AnyVolumeDataSouce feature gate defaults to enabled in Kubernetes v1.24, which means that users can specify any custom resource as the data source of a PVC.

    An earlier blog article detailed how the volume populators feature works. In short, a cluster administrator can install a CRD and associated populator controller in the cluster, and any user who can create instances of the CR can create pre-populated volumes by taking advantage of the populator.

    Multiple populators can be installed side by side for different purposes. The SIG storage community is already seeing some implementations in public, and more prototypes should appear soon.

Linux 5.18-rc7

	
From	Linus Torvalds

Subject	Linux 5.18-rc7
share 0
So things continue to be fairly calm, and as such this is likely the
last rc before 5.18 unless something bad happens next week.

All the stats here look normal, with the bulk of it being random
driver updates (network drivers, gpu, usb, etc).

There's a few filesystem fixes, some core networking, and some code
kernel stuff. And some selftest updates.

Sortlog appended, nothing really stands out (the most exciting thing
last week was literally that Andrew has started using git, which will
make my life easier, but that doesn't affect the *code*)

Please give it one last week of testing, so that we'll have a nice
solid 5.18 release.
