Red Hat: Systemd, PulseAudio, Survey and OpenStack

  • Where I Stand on Systemd

    Once I turn to design considerations and technological benefits, however, I quickly bog down. The Unix philosophy of one utility to do one thing very well sounds admirable in theory, and perhaps on the administrative level it works well. Yet, I have heard few if any complaints that large apps like SE Linux or AppArmor violate the Unix philosophy, and on the desktop, apps like LibreOffice or Krita are clear violators. Could it be that some projects require a different approach to be effective?

    As a user, my initial tendency is to applaude Init Freedom’s rejection of “this one-size-fits-all vision” that led to the general acceptance of systemd in the major distributions. Yet as I think further, I wonder how practical supporting multiple init systems might be.

    In the recent Debian general resolution on systemd, both sides maintained that expecting maintainers to support multiple init systems would seriously add to the task of keeping packages current. The Devuan project itself appears to illustrate the difficulty, since it still uses Debian 9 as its basis and so far has been unable to add multiple init support itself. When finding maintainers is a constant problem for many distros, perhaps a limit on the number of supported init systems is sheer practicality.

  • PulseAudio 14 Is Releasing Soon With Better USB Gaming Headset Support

    In addition to PipeWire 0.3 having shipped last week, also making it out a few days prior was a development snapshot in the road to PulseAudio 14.0.

    PulseAudio 13.99.1 was released as a development snapshot in the road to the imminent PulseAudio 14.0.

    In the 6+ months since PulseAudio 13, developers have been working on various audio sink changes, automatic switching to HDMI audio is now disabled by default, flat volumes are also disabled by default, there is better support for USB gaming headsets, PulseAudio honoring Xauthority arguments for X11 modules, a workaround for GNOME Sound Settings behavior, and various other changes.

  • Enterprise open source software is growing within innovative companies

    Red Hat has been at the forefront of the global open source discussion, fighting for software freedom in the U.S Supreme Court, and offering free tech products for cloud infrastructure, automation, AI, and much more. After conducting research and interviewing IT leaders from around the world, Red Hat released a report examining the state of enterprise open source in 2020.

    950 IT leaders, unaware that Red Hat was the research sponsor, were surveyed about their practices and opinions on enterprise open source software.

    [...]

    The benefits of using open source software seem obvious, namely that they are, of course, freely available. However, its lack of a price tag isn’t the main thing that IT leaders love.

    According to the survey, respondents believe that higher-quality software is the number one benefit of enterprise open source. FOSS software is often better than proprietary options, with better security, cloud-native technologies, and cutting edge solutions.

  • Red Hat OpenStack Platform 16 Delivers Long-Term Support

    On Feb. 20, Red Hat announced OpenStack Platform 16, a major update providing up to five years of support. The update is the first of 2020 and marks the beginning of a new approach to OpenStack support from Red Hat. Up until the OpenStack 15 release in September 2019, Red Hat released two minor updates every year that had up to one year of support, followed by a major long-term support release. As of the Red Hat OpenStack Platform 16 release, there will now only be long-term support releases.

  • SD Times Open-Source Project of the Week: Discover archetypes

    IBM wants to help developers identify and classify archietypes in data with the release of a new code pattern.

    Archetypes are formally defined as a pattern, or a model, of which all things of the same type are copied. According to the company, its Watson natural language understanding helps users discover archetypes in their text corpus.

    “When we read through a set of these records, our mind naturally groups the records into some collection of archetypes. For example, we may sort a song collection into easy listening, classical, rock, etc. This manual process is practical for a small number of records (e.g., a few dozen). Large systems can have millions of records, so we need an automated way to process them,” IBM wrote in a blog post.

  • Orange Egypt Using Red Hat for Horizontal Cloud Rollout

    Red Hat has been a recognizable name in the open-source community for decades. Now, Orange Egypt is utilizing the open-source provider as a basis for its horizontal cloud development. The telecommunications provider opted for the open-source solution based on reliability and cost-effectiveness. Red Hat states that Orange Egypt is the first Orange affiliate to offer management of all of its customer traffic using a software-based platform covering several sites within the geographic area. The company has invested in Red Hat technologies and already utilizes the Red Hat OpenStack Platform alongside Red Hat Ceph Storage.

  • Everything OK down there in the Oracle trench? Good. Big Red has a cloud-based data science platform for you

    After securing a lofty position in enterprise applications and databases, Oracle has fixed its eyes on data science. And though analysts have expressed doubt about whether Big Red is producing technologies new to the field, its shiny Cloud Data Science Platform might appeal to those already heavily invested in Oracle's software.

    Big Red's pitch is that it will bring cohesion to efforts in data science, allowing practitioners to "collaboratively build, train, manage and deploy machine learning models".

    Via the Oracle Cloud Infrastructure Data Science service, data scientists will, the vendor said, be able to automate algorithm selection and tuning, automate predictive feature selection, evaluate models and make machine-learning models explainable to the outside world.

  • Stuffed Ep 34 – How open-source is solving the world’s biggest problems

    Open-source software has evolved to be integrated into every part of our lives. Even if we don’t necessarily know it. Proprietary software will likely become almost redundant as we move into cloud-accessible open-source options. Toby Shapshak speaks to Red Hat’s Lee Miles to delve into more accessible software.

    “When development is distributed, the risk of failure goes down.” Red Hat provides open-source solutions and software options to businesses and individuals. It focuses on high-performing Linux, cloud, container, and Kubernetes technologies — but the portfolio is growing as the software industry ‘opens’ up. The top areas where open-source software is being applied within the enterprise are security, cloud, database, and big data and analytics. Enterprises that use this software like to leverage open source for specific industry needs, like IT infrastructure modernisation, application development, and DevOps.

  • Use of proprietary software is 'plummeting', finds Red Hat report

    Red Hat's annual research report The State of Enterprise Open Source has found a big rise in the use of enterprise open-source software, and, to a lesser extent, community-based open-source solutions...

  • Report: The benefits of open-source software go beyond cost

    Open-source adoption is not slowing down within enterprises. A recent report found 95% of enterprises are taking open source seriously, with 75% of them reporting that open-source software is extremely important to their IT strategies. That number is up from 69% last year.

    The 2020 State of Enterprise Open Source by Red Hat is based off of 950 interviews conducted with IT leaders worldwide.

    “For our second annual report, we wanted to know more. With 95% of IT leaders agreeing that enterprise open source is important to their enterprise infrastructure software strategy, it’s safe to say we don’t need to ask ‘if’ anymore. We need to ask ‘why’ and ‘how,’” Jim Whitehurst, president and CEO of Red Hat, wrote in the report.

  • Greenpeace takes open-source approach to finish web transformation

    Greenpeace is working with open source software firm Red Hat to scale and revamp its grassroots engagement platform, Planet 4.

    The project marks a complete re-design of Greenpeace.org’s backend content management systems (CMS), which are now designed to put content on the web and provide a vehicle for driving grassroots environmental action.

  • Greenpeace turns to Red Hat to scale its “Planet 4” global engagement platform
  • Greenpeace turns to open source to finish its web transformation

    In 2016, Greenpeace International decided to try a new way of stimulating grass-level environmental activity via something it called ‘Planet 4’ - a global content management system (CMS) it defined as its new engagement platform. In its original mission statement, it also outlined its expectations for the tool: that it would foster more engagement “when we present ourselves to our supporters, and our potential supporters, through a clear representation of our values with a clear proposition for why we exist, how people can become change agents through our work, and what they can do with us right now”.

  • Network Automation: Why organizations shouldn’t wait to get started

    For many enterprises, we don’t need to sing the praises of IT automation - they already get it. They understand the value of automation, have invested in a platform and strategy, and have seen first-hand the benefits IT automation can deliver. However, unlike IT automation, according to a new report from Forrester Research 1, network automation is still new territory for many organizations.

    The report, "Jump-Start Your Network Automation," found that 56% of global infrastructure technology decision makers have implemented/are implementing or are expanding/upgrading their implementation of automation software, while another 19% plan to implement it over the next 12 months. But those same organizations that are embracing IT automation haven’t necessarily been able to take that same initiative when it comes to automating their networks.

    Even if they know it will be beneficial to them, the report found that organizations often struggle with even the most basic questions around automating their networks.

  • Using a story’s theme to inform the filmmaking: Farming for the Future

    The future of farming belongs to us all. At least that’s the message I got from researching Red Hat’s most recent Open Source Stories documentary, Farming for the Future. As a self-proclaimed city boy, I was intrigued by my assignment as director of the short documentary, but also felt like the subject matter was worlds away. If it did, in fact, belong to all of us how would we convey this to a general audience? How could we use the film’s theme to inform how we might approach the filmmaking to enhance the storytelling?

  • Raptor Rolls Out New OpenBMC Firmware With Featureful Web GUI For System Management

    While web-based GUIs for system management on server platforms with BMCs is far from anything new, Raptor Computing Systems with their libre POWER9 systems does now have a full-functioning web-based solution for their OpenBMC-powered systems and still being fully open-source.

    As part of Raptor Computing Systems' POWER9 desktops and servers being fully open-source down to the firmware/microcode and board designs, Raptor has used OpenBMC for the baseboard management controllers but has lacked a full-featured web-based system management solution on the likes of the Talos II and Blackbird systems up until now.

  • Introduction to open data sets and the importance of metadata

    More data is becoming freely available through initiatives such as institutions and research publications requiring that data sets be freely available along with the publications that refer to them. For example, Nature magazine instituted a policy for authors to declare how the data behind their published research can be accessed by interested readers.

    To make it easier for tools to find out what’s in a data set, authors, researchers, and suppliers of data sets are being encouraged to add metadata to their data sets. There are various forms for metadata that data sets use. For example, the US Government data.gov site uses the standard DCAT-US Schema v1.1 whereas the Google Dataset Search tool relies mostly on schema.org tagging. However, many data sets have no metadata at all. That’s why you won’t find all open data sets through search, and you need to go to known portals and explore if portals exist in the region, city, or topic of your interest. If you are deeply curious about metadata, you can see the alignment between DCAT and schema.org in the DCAT specification dated February 2020. The data sets themselves come in various forms for download, such as CSV, JSON, GeoJSON, and .zip. Sometimes data sets can be accessed through APIs.

    Another way that data sets are becoming available is through government initiatives to make data available. In the US, data.gov has more than 250,000 data sets available for developers to use. A similar initiative in India, data.gov.in, has more than 350,000 resources available.

    Companies like IBM sometimes provide access to data, like weather data, or give tips on how to process freely available data. For example, an introduction to NOAA weather data for JFK Airport is used to train the open source Model Asset eXchange Weather Forecaster (you can see the model artifacts on GitHub).

    When developing a prototype or training a model during a hackathon, it’s great to have access to relevant data to make your solution more convincing. There are many public data sets available to get you started. I’ll go over some of the ways to find them and provide access considerations. Note that some of the data sets might require some pre-processing before they can be used, for example, to handle missing data, but for a hackathon, they are often good enough.

  • Building a community of practice in 5 steps

    In the first part of this series, we defined community as a fundamental principle in open organizations, where people often define their roles, responsibilities, and affiliations through shared interests and passions, not title, role, or position on an organizational chart. Then, in the second part of the series, we explored the many benefits communities of practice bring to open organizations—including fostering learning, encouraging collaboration, and offering an opportunity for creative problem-solving and innovation.

    Now you know you'd like to start a community of practice, but you may still be unsure where to start. This article will help define your roadmap and build a plan for a successful community of practice—in five simple steps (summarized in Figure 1).

Red Hat: libinput, backports, edge computing, survey and more

Filed under
Red Hat
  • Peter Hutterer: A tale of missing touches

    libinput 1.15.1 had a new feature: it matched the expected touch count with the one actually seen as opposed to the one advertised by the kernel. That is good news for ALPS devices whose kernel driver lies about their capabilities because these days who doesn't. However, in some cases that feature had the side-effect of reducing the touch count to zero - meaning libinput would ignore any touch. This caused a slight UX degradation.

    After a bit of debugging and/or cursing, the issue was identified as a libevdev issue, specifically - the way libevdev replays events after a SYN_DROPPED event. And after several days of fixing things, adding stuff to the CI and adding meson support for libevdev so the CI can actually run a few useful things, it's time for a blog post to brain-dump and possibly entertain the occasional reader such as you are. Congratulations, I guess.

    The Linux kernel's evdev protocol is a serial protocol where all events have a type, a code and a value. Events are grouped by EV_SYN.SYN_REPORT events, so the event type is EV_SYN (0), the event code is SYN_REPORT (also 0). The value is usually (but not always), you guessed it, zero. A SYN_REPORT signals that the current event sequence (also called a "frame") is to be interpreted as one hardware event [0].

  • What is backporting, and how does it apply to RHEL and other Red Hat products?

    Version numbers are important, but aren't always what they seem at first glance. Red Hat, for example, often backports updates to the software we ship in Red Hat Enterprise Linux (RHEL) to maintain the version that we shipped.

    This is a post to follow to Jean-Sébastien Tougne’s post on finding the latest available kernel. Jean-Sébastien’s article was responding to a question on the Red Hat Learning Community, where the poster was seeking the latest version of the kernel for Red Hat Enterprise Linux. That prompted me to write an article that went deeper into the nuance and strategy the Red Hat Enterprise Linux team employs for this to be magically delicious for administrators.

  • The edge is open: Why scale-out computing doesn’t exist without open hybrid cloud

    The past year has seen the rise of applications that push enterprise IT to the (literal) edge, from using autonomous vehicles guided by artificial intelligence (AI) to vast sensor networks that rely on 5G for instant connectivity and emergency reaction times. Whether it's the Internet-of-Things (IoT), fog computing or edge computing, the intent is to bring computing resources like processing power and storage closer to the end user or data source to improve the ability to scale, responsiveness and the overall service experience.

    We can look at the edge as the newest IT footprint, becoming an extension of the data center just like bare-metal, virtual environments, private cloud and public cloud. In a sense, edge computing is a summation of the other four footprints, blending pieces from each to create infrastructure aimed at tackling specific customer demands that traditional IT models cannot address.

Fedora VS Ubuntu

Ubuntu

Linux is superior to Windows in a lot of ways. It gives you the freedom to shape your system according to your desire. You can customise almost everything to your taste. Don’t like the way your login screen looks, well change it according to your liking. You can change your Linux UI (User Interface) so that it looks like Windows if you are more comfortable that way. Linux is way less resource-hungry than Windows, meaning it runs a lot smoother. You can even customise how much cache and ram should Linux use. But despite all these good things switching from Windows to Linux can be a lot of hassle as there are a lot of distros or types of Linux to choose from and most people get confused. Different Linux distros are for different people. Here I’ll be comparing the two biggest distro releases, i.e., Ubuntu and Fedora

Where do you turn when you have a fleet of public workstations to manage? If you’re the Czech National Library of Technology (NTK), you turn to Fedora. Located in Prague, the NTK is the Czech Republic’s largest science and technology library. As part of its public service mission, the NTK provides 150 workstations for public use.

In 2018, the NTK moved these workstations from Microsoft Windows to Fedora. In the press release announcing this change, Director Martin Svoboda said switching to Fedora will “reduce operating system support costs by about two-thirds.” The choice to use Fedora was easy, according to NTK Linux Engineer Miroslav Brabenec. “Our entire Linux infrastructure runs on RHEL or CentOS. So for desktop systems, Fedora was the obvious choice,” he told Fedora Magazine.

  • Designing an event-driven business process at scale: A health management example, Part 1

    The concept of a business process (BP), or workflow (WF), and the discipline and practice of business process management (BPM) have been around since the early 90s. Since then, WF/BPM tools have evolved considerably. More recently, a convergence of different tools has taken place, adding decision management (DM) and case management (CM) to the mix. The ascendance of data science, machine learning, and artificial intelligence in the last few years has further complicated the picture. The mature field of BPM has been subsumed into the hyped pseudo-novelties of digital business automation, digital reinvention, digital everything, etc., with the addition of “low code” and robotic process automation (RPA).

    A common requirement of business applications today is to be event-driven; that is, specific events should trigger a workflow or decision in real-time. This requirement leads to a fundamental problem. In realistic situations, there are many different types of events, each one requiring specific handling. An event-driven business application may have hundreds of qualitatively different workflows or processes. As new types of events arise in today’s ever-changing business conditions, new processes have to be designed and deployed as quickly as possible.

    This situation is different than the common requirement of scalability at runtime. It’s not just a problem of making an architecture scale to a large number of events per second. That problem is in many respects easy to solve. The problem of scalability at design time is what I am concerned about here.

  • Satellite and Ansible Tower Integration part 2: Provisioning callbacks

    Satellite and Ansible Tower are each powerful tools, and many customers utilize both of them. It is possible to integrate these tools and in part 1 of this series we covered how to configure Ansible Tower to pull a dynamic inventory of hosts from Satellite. 

    One of Satellite’s features is the ability to provision new hosts, while one of Ansible Tower’s main features is the ability to configure hosts. By integrating these tools, Red Hat Enterprise Linux (RHEL) hosts provisioned by Satellite can be configured to automatically make a provisioning callback to Ansible Tower. This provisioning callback functionality allows you to run an Ansible playbook on the new RHEL host so it can be configured using the Ansible Tower infrastructure. The end result is the ability to go into Satellite, provision a new host, and automatically obtain a configured host via Ansible Tower. This can save system administrators time and allow them to meet the needs of their organization. 

    One of the prerequisites for setting up provisioning callbacks is having Satellite configured as a dynamic inventory source within Ansible Tower so, if you haven't already, first follow the steps outlined in the previous blog post.

Dual-Boot GNU/Linux and Android

  • Planet Computers' clamshell phone can dual-boot Android and Linux

    Planet Computers' laptop-like Cosmo Communicator phone just became that much more useful to its audience of very particular power users. The Cosmo now supports a promised multi-boot function, letting you run Android (both regular and rooted), Debian Linux and TWRP on the same device without one replacing the other. You'll have to partition your storage and know your way around a boot menu, but this will give you a way to run Linux apps or otherwise experiment with your phone. You won't lose over-the-air updates for Android by installing Linux, Planet Computers said. The multi-boot firmware is available for free, and there are instructions for installing Debian and other software. This still isn't for the faint-hearted. However, it also represents one of the few instances where a phone maker has officially enabled support for operating systems besides the one that ships with the device. The Cosmo is also fairly well-suited to Linux thanks to its keyboard -- you won't have to jump through hoops to use the command line.

  • How can IT manage Android Things devices in the enterprise?

    Recent versions of Google's Android OS support a wider range of devices via the Android Things program's APIs and managing some of the newer devices can seem complicated at first. Thankfully, the underlying OS is essentially the same on all Android devices, so the EMM platform management and enrollment processes are usually similar for Android Things devices. The challenge for mobile admins is to develop a version of Android -- using the Android SDK and Android Things APIs -- that functions on these dedicated devices.

Update on Linux support: creation of a CERN Linux community forum

For those, a CERN Linux community forum has been created. Users will be able to post issues that they encounter when using non-CERN-supported Linux distributions and to post solutions. Users are also encouraged to post articles with comments and ideas that could help make this forum more dynamic and useful to them. Various methods for printing and using AFS, SSH, ROOT and other tools at CERN can be found on the internet. The CERN Linux community forum aims to collect these methods, as well as new ones that may be created directly in it. Read more

Python Programming

  • Introduction to Python SQL Libraries

    All software applications interact with data, most commonly through a database management system (DBMS). Some programming languages come with modules that you can use to interact with a DBMS, while others require the use of third-party packages. In this tutorial, you’ll explore the different Python SQL libraries that you can use. You’ll develop a straightforward application to interact with SQLite, MySQL, and PostgreSQL databases.

  • Introduction to Image Processing in Python with OpenCV

    In this tutorial, we are going to learn how we can perform image processing using the Python language. We are not going to restrict ourselves to a single library or framework; however, there is one that we will be using the most frequently, the Open CV library. We will start off by talking a little about image processing and then we will move on to see different applications/scenarios where image processing can come in handy. So, let's begin!

  • Talking to API's and goodlooking tools

    One of my go-to locations for security news had a thread recently about a tool called VTScan. I really liked the idea of not having to go through the browser overhead to check files against multiple scan engines. Although the tool (which is itself a basic vt-cli spinoff) already existed, I was looking for a new challenge, I decided to roll my own and add a few cool features! I'll have a thorough look at how python talks to API's with requests and I look at turning all this API data into a nice GUI application with click. I hope to give you some idea's for CLI styling in the future so I can see more awesome tools by you all!

  • From a rejected Pycon talk to a new project.

    Like many others, my talk proposal (early draft here) for Pycon US was rejected. So, I decided to spend some time putting everything in a new project instead. (Documentation here.) It is still a rough draft, but usable ... and since I've mentioned it in a few other places, I thought I should mention it here as well.
