Oracle is pleased to announce the general availability of Oracle Linux Cloud Native Environment Release 1.3. This release includes several enhancements focused on improving the security and compliance features of customer environments. Release 1.3 also includes new versions of core components, including Kubernetes, CRI-O, Kata Containers, Istio, and so on.
Oracle Linux Cloud Native Environment is an integrated suite of software components for the development and management of cloud native applications. Based on the Cloud Native Computing Foundation and Open Container Initiative standards, Oracle Linux Cloud Native Environment delivers a simplified framework for installation, update, upgrade, and configuration of key features for orchestrating microservices.
Oracle is pleased to announce the availability of the Oracle Linux 8 Update 4 for the 64-bit Intel and AMD (x86_64) and 64-bit Arm (aarch64) platforms. Oracle Linux brings the latest open source innovations, business-critical performance, and security optimizations for cloud and on-premises deployment. Oracle Linux maintains user space compatibility with Red Hat Enterprise Linux (RHEL) and CentOS, which is independent of the kernel version that underlies the operating system. Existing applications in user space will continue to run unmodified on Oracle Linux 8 Update 4 with Unbreakable Enterprise Kernel Release 6 (UEK R6) and applications already certified on previous releases of Red hat Enterprise Linux 8 or Oracle Linux 8 do not require a certification with this new release.
Derived from Red Hat Enterprise Linux 8.4 and fully compatible with both Red Hat Enterprise Linux (RHEL) and CentOS Linux distributions, Oracle Linux 8.4 is now available for download as a free alternative Linux server for cloud and on-premises deployments of any size.
Powered by the Unbreakable Enterprise Kernel (UEK) Release 6 Update 2, which is running Linux 5.4.17-2102.201.3, available for both 64-bit (x86_64) and ARM64 (AArch64) platforms, Oracle Linux 8.4 also features the latest Red Hat Compatible Kernel as Linux 4.18.0-305 only for 64-bit (x86_64) platforms.
I occasionally need to benchmark the tools I try out in videos but doing so can be a little bit annoying, it turns out however, that there is a tool called Hyperfine which make the process incredibly easy. I wish I knew about this earlier.
We both fall for a new fancy keyboard; then we get philosophical about free software’s never-ending quest to conquer mobile.
History and freedom share the front seat as Fred Stutzman tells Doc Searls and Shawn Powers about how Sunsite became Ibiblio: one of the most important resources on the Internet—and how he grew personally through all that history. And then how he started and runs Freedom.to, a leading screen time product that helps people protect themselves from their own distractions—and how he bootstrapped the company without VC money while remaining involved in the open-source world.
It’s time we pushed forwards in our exploration of XFCE, this time, we’re going to look at the default applications that this desktop ships, and reflect a little bit on their approach, that is really different from other desktop environments
The AMD Ryzen 5 5500U with six cores / twelve threads within a Lenovo laptop at $449 USD is quite a steal. This is also my first time benchmarking the AMD Ryzen 5 5500U after waiting months on Ryzen 5000 series laptop availability. Here are some initial benchmarks of the Ryzen 5 5500U under Ubuntu 21.04 Linux against various other Intel/AMD laptops.
The Ryzen 5 5500U is a Zen 2 based laptop processor rather than Zen 3 with the higher-end 5000 series models. However, over the previous-generation Ryzen 5 4500U, there is now SMT to offer 12 threads rather than 6/6 with the prior generation. The 5500U though carries a 2.1GHz base frequency rather than the 2.3GHz base with the 4500U while both have a turbo up to 4.0GHz. The 5500U also has the benefit of a 64K L1 cache per core rather than 32K.
Inkscape, the free software, will never stop looking at its framework to compete with Adobe Illustrator and attracting illustrators, amateurs and
Chrome browser is the popular one, available for Linux, Windows, macOS, Android, and iPhone. It comes with an integrated translation of websites based on Google Translate. Its installation on other operating systems is pretty much easier as compared to Linux because it is a proprietary browser. However, its open-source version that is Chromium is very easy to download and set up because of its availability in the default repository of Linux. Although both Chrome and Chromium are exactly the same, however, still if your want to install Google’s Chrome on your Debian 11 Bullseye or 10 Buster Linux distros then here is the tutorial on it.
Given that Debian is the mother of so many Linux distributions, it should come as no surprise that it makes for a great server platform. It’s incredibly stable, secure and easy to use. And, like Ubuntu, Debian offers a Long Term Support release, which means support will last for five years.
OBS, or Open Broadcasting Software, is a completely free broadcasting program you can use to record all types of media. Many streamers use OBS to capture their gameplay or webcam footage and stream it live to viewers. However, have you thought about using OBS to record audio only?
AppImage is a type of application package that can be run directly on Linux distributions without installation. Usually, users can immediately run this application by double clicking or right clicking and selecting the execute menu.
To manage AppImage files, you can use AppImageLauncher. This application has a small size and is one of the applications that I recommend you use to make it easier to manage some of the appimage applications that you run on Linux distributions. Please visit this page to try AppimageLauncher.
Today we are looking at how to install OnlyOffice Desktop on a Chromebook Please follow the video/audio guide as a tutorial where we explain the process step by step and use the commands below.
User management becomes a critical consideration when you want to add multiple users to the system. If user management on your system is not effective, you may have to compromise security and access to the private and sensitive information on your system. This article introduces simple techniques you can use to have effective control over user management. It covers user and group management procedures, both from the user interface and from the command line, that you can perform with very simple steps.
We run the commands and processes described in this article on an Ubuntu 20.04 system. Please note that you must have root privileges to perform the tasks described here. So let’s first understand what root is?
Until recently, I worked for Canonical on the Snap Advocacy Team. Some of the things in this blog post may have changed or been fixed since I left. It’s quite a long post, but I feel it’s neccessary to explain fully the status-quo. This isn’t intended to be a “hit piece” on my previous employer, but merely information sharing for those looking to control their own systems.
I’ve previously provided feedback in my previous role as Snap Advocate, to enable them to better control updates. However, a lot of this feedback was spread over forum threads and other online conversations. So I thought I’d put together some mitigations and the steps I take in one place.
At the end of this post I detail what I do on my systems to be in more control of snap updates. Skip to that if you know what you’re doing.
NewsFlash is a program designed to complement an already existing web-based RSS reader account.
It combines all the advantages of web based services like syncing across all your devices with everything you expect from a modern desktop program: Desktop notifications, fast search and filtering, tagging, handy keyboard shortcuts and having access to all your articles as long as you like.
But that’s not a hard requirement; NewsFlash can be used “locally” if you don’t want to bother with cross-platform syncing and so on.
setup Redis cache for my web app. I want a blank database and get rid of all keys. How can I delete everything in Redis cache? How do I flush my Redis cache using the Linux/Unix command line option? What is the command to delete all keys from my redis cluster?
Arch Linux is an independently developed X86_64 optimized distribution system for Open hand Linux users. It uses its own PACMAN package manager to provide updates to the latest application with full dependency tracking. It is based on Rolling release system. For instance, We can do the installation with a CD or a Bootable drive via an FTP server. The default installation provides the core base of this distribution that can be further customized as per the user requirements and needs.
MongoDB is an open-source doc database utilized in quite a few trendy Net purposes. MongoDB is also called Mongo. It’s categorized as a NoSQL database as a result of it doesn’t have a conventional relational database construction primarily based on the desk.
Not like relational databases, it makes use of dynamically primarily based JSON-like paperwork, that means that MongoDB requires no predetermined schema earlier than you add information into it. You possibly can change the construction anytime, with out establishing a brand new database replace construction.
Epic Games today pushed Unreal Engine 5 out to early access. Like with UE4, Unreal Engine 5 continues offering native Linux support and allowing use of the Vulkan API.
Unreal Engine 5 is not yet considered production ready but is available in this early form for anxious developers wishing to begin experimenting with this next-generation game engine.
Material Shell has been updated recently with GNOME Shell 40 support, new overview as well as new Gtk4 settings.
This is not just a simple GNOME Shell extension. Material Shell completely changes the GNOME Shell user interface to “simplify navigation and reduce the need to manipulate windows in order to improve productivity”.
Among its many features is a tiling engine that can automatically organize windows into multiple layouts, including maximize, split, simple, half, grid and ratio. If you want to use traditional floating windows, that’s available too.
There’s no denying that Manjaro is one of the most popular distros in the GNU/Linux world, and there are several reasons for this. First, it’s based on Arch but is still very easy to install. Second, it is one of the best distros for beginners who want to get their hands dirty with Arch, and last but not least, it has one of the best communities in the Linux space that’ll help you out when you’re stuck.
There are two main Manjaro versions – Official and Community. Today marks the release of another Manjaro community edition release which goes by the name CutefishOS.
The fifth major release of Univention Corporate Server is ready and available for download. UCS 5.0 contains new features, has a fresh look, comes with several improvements and bug fixes. The new version also uses a new core: UCS 5.0 is based on Debian 10 (“Buster”) and Python 3.
In this blog post, I would like to introduce the most important changes, give tips for the upgrade process and reveal what we’re planning for future releases.
Today we have released to the public the beta version of EuroLinux 8.3. This is a test version of the software. Its release is the effect of few months of hard work of the EuroLinux team. During production, we created new build systems and extended QA procedures for this product.
Our mission is to create not only the best, according to the market standard, Enterprise Linux but also to add to it some key technological advantages and features. They constitute an added value in relation to other vendors while maintaining full compatibility with the upstream.
The beta release is an essential step in the development of the software, but it does not hold back further goals and projects. There is a lot of work ahead of us in the very near future, the results of which will be made available soon – more information in our roadmap below.
Revenue reached $17.7 billion in the first quarter, up from $17.6 billion the year before. However, net income fell from $1.175 billion to $955 million. IBM claimed the revenue improvement was due to a surge in cloud operations. However, its “Cloud & Cognitive Software” revenue rose less than 4%. IBM has not made a dent in the strength of cloud market leaders Amazon, Microsoft or Google.

Krishna has done nothing to improve IBM’s situation, and he has not articulated plans that give investors reasons to believe the future will be better.
Earthquakes killed over 800,000 people globally between 2000 and 2015, and almost one-third of the world’s population (some 2.7 billion people) live in seismically active regions. For those in the strike zone of an impending earthquake, every second matters. Earthquake early-warning (EEW) systems are essential in providing real-term alerts to nearby populations before the shaking arrives – giving people time to gather essentials and assist loved ones in getting to safety. The alerts can also trigger automatic systems that stop elevators, prepare backup power, and turn off gas pipes.
However, due to the incredibly high cost of traditional seismometers, dedicated telecommunications, and bespoke software, only a handful of governments have attempted to build EEW systems, leaving hundreds of millions at risk. Grillo, a social enterprise born in Mexico City and dedicated to the development of IoT solutions for seismically vulnerable communities, is working to change that.

We’re gearing up to welcome you to Red Hat Summit Virtual Experience Part 2 on June 15 and June 16. Here’s just a glimpse of what’s in store.
As organizations are adopting agile and DevOps to improve their processes and products at breakneck speed, security considerations may be left in the dust and digital risks left unmanaged. Therefore, organizations must have security automation as part of their digital transformation. This article intends to provide you with security basics and an automation approach to assess platforms, products, and services to comply with security policies, regulatory, and compliance requirements.
A prime requirement of security is to mitigate the risks exposed by vulnerabilities that can be exploited by a threat actor, such as an attacker, to cross privilege boundaries within a system. Many known vulnerabilities are discovered by researchers, groups, and individuals who invest their time and report it.
To streamline the efforts, MITRE Corporation maintains publicly disclosed vulnerabilities in a system called Common Vulnerabilities and Exposures (CVE) and Open Vulnerabilities and Assessment Language (OVAL) definitions to describe the desired configuration of systems in machine-understandable format. Security Content Automation Program (SCAP) uses OVAL to automate systems assessment and discover discrepancies to the desired state.
Cockpit is the modern Linux admin interface. We release regularly.
Here are the release notes from Cockpit version 245 and cockpit-podman version 31.
Derived from the freely available sources of the recently released Red Hat Enterprise Linux 8.4 operating system, AlmaLinux OS 8.4 is here to inherit all of its new features and improvements, such as support for the Intel “Tiger Lake” GPU family like Intel UHD and Intel Xe graphics, two new system roles, as well as improved edge computing capabilities.
On top of that, the AlmaLinux OS 8.4 release is here to introduce full support for the Secure Boot security standard, which means that you can now safely install the distribution on a computer with Secure Boot enabled.
Following last week’s release of Red Hat Enterprise Linux 8.4, various downstreams are beginning to release their respective updates based against the RHEL 8.4 changes.
Oracle has announced Oracle Linux 8 Update 4 for x86_64 and AArch64. This is Oracle’s Linux distribution with the RHEL 8.4 source changes pulled in. Plus Oracle continues to offer their “Unbreakable Enterprise Kernel” as a newer Linux kernel build alternative to their Red Hat Compatible Kernel (RHCK) that tracks just the upstream RHEL kernel changes.
More details on Oracle Linux 8 Update 4 can be found via the Oracle Linux blog.
Hey, what are you doing for Memorial Day? Heading out of town? Having a few friends over (that used to be a thing once upon a time)? How about having yourself a good old fashioned installfest? That’s right! The AlmaLinux OS Foundation is proud to announce the release of AlmaLinux OS 8.4 Stable. Available now on a mirror near you! Download a fresh copy and then join us to talk about it.
Released last year in April, Fedora Linux 32 brought the Linux 5.6 kernel series with built-in WireGuard VPN support, the GNOME 3.36 desktop environment for Fedora Workstation, EarlyOOM system service by default to improve the user experience on machines with low memory, support for Rockchip-powered devices, and a new Fedora Lab edition called Fedora 32 Comp Neuro Lab for computational neuroscience.
Since each new Fedora Linux release is supported for about 13 months, the time has come to say goodbye to the Fedora Linux 32 release as it now reached of life on May 25th, 2021. It was maintained 392 days, but it will now no longer receive any type of support, so you should upgrade to a supported Fedora Linux release as soon as possible after reading this article.
We (the Ubuntu Community team) are delighted to invite you to the UbuntuOnAir YouTube and Twitch channels! These particular airwaves will hold community-focused Indabas, office hours, highly requested community interviews and will deliver Ubuntu/Open Source related workshops, host special events, and, hopefully, yes, play games.
Blinkinlabs’ $27, open-spec “JTAG HAT” that turns the Raspberry Pi into an OpenOCD compatible MCU debugging device with built-in Arm Cortex-M and JTAG headers.
Netherlands-based Blinkinlabs has launched a JTAG debugging HAT for the Raspberry Pi for 22 Euros ($27) that supports the open source OpenOCD debugging software. The JTAG HAT is equipped with a 10-pin, 1.27mm Cortex-M Debug Connector that supports level-shifted JTAG (TCK/TMS/TDI/TDO) or SWD (SWDIO/SWDCLK) debugging pins. There is also a standard 20-pin JTAG header with 0.1-inch headers for “easy connection to boards with older or no pins.”
The word “robotic arm” normally conjures up images of huge devices used in auto plants or on space shuttles. While there are many types of robotic arms used in a myriad of industries, there has never been one as small and portable as the 850g myCobot – the world’s smallest collaborative robotic arm. And now, the robot has launched a new version that uses Raspberry Pi.
The myCobot, jointly produced by Elephant Robotics and M5STACK, was released last year and became popular with the maker and robotics communities. Initially, the robotic arm only used Arduino. After feedback from consumers, the company has now expanded its myCobot series to create the myCobot-Pi, which adopts a Raspberry Pi microprocessor.
The myCobot-Pi six-axis collaborative robot is a multi-functional and lightweight intelligent robotic arm. Users of the robot can personally customize the robotic arm, as it supports multi-platform secondary development and can effectively help users achieve multi-scene application development.
“Bend an existing Linux distribution to run on smartphones.” This is what we set out to do four years ago, and it has been quite the success. Alpine Linux, with the thin postmarketOS layer on top, is now able to boot on an ever increasing, insane number of currently 289 mobile devices.
While most of these run downstream Linux kernels and can only be used as Raspberry Pi-like tinkering devices, it is still a huge accomplishment by our amazing community. But even greater feats are the devices running (close to) mainline kernels, such as the eleven phones present in our latest release. These became quite usable for Linux enthusiasts, and some people are daily driving them.
There is still lots of work to do, but at the same time it is clear now that the concept of running real Linux distributions on smartphones has a foot in the door. As the PinePhone and Librem 5 showed up, more and more amazing projects with similar missions were started on a wide range of Linux distributions. This has lead to more people getting involved, and more collaborations upstream. Most notably Mobian, who we have a long history of collaborating with on projects like osk-sdl, the on-device installer, PinePhone modem improvements and other components. We congratulate the Mobian developers for adding support for two mainlined SDM845 Android phones. Linux distributions on smartphones are here to stay!
Observability platform provider New Relic Inc. is beefing up its product with a new “Kubernetes experience” that it says will enable instant insights into the software container orchestration system without needing to update any code or sample data first.
The company also announced enhancements around its error tracking, network monitoring and programmability capabilities, plus two new community-focused versions of its platform. The announcements, during New Relic’s annual developer conference FutureStack 2021, are meant to help customers adopt a more data-driven approach to observability that informs how they build, operate and deploy new software.
[...]
The New Relic One platform is popular, but the company has struggled to turn a profit.
The PGCon 2021 Unconference is this upcoming Friday, May 28th starting at 10 AM.
You may have heard that the Rust 2021 Edition is coming. Along with my daughter Daphne, I have recorded a little song in honor of the occasion!
During my work on Web Compatibility at Mozilla, I see many things that break in exciting ways. Sometimes, it’s obvious stuff like flexbox compat issues1, but sometimes, the breakages are a bit surprising. Today, the star of the show is a single CSS instruction:
text-indent: -9999px When we talk about web compatibility issues, most people think about an elite subset of “well-known” breakages or massive layout issues. They rarely think about innocent-looking things like text-indent. And to be fair, most of the time, neither do we browser people.
Today the European Commission published its guidance for the upcoming revision of the EU Code of Practice on Disinformation. Mozilla was a founding signatory of the Code of Practice in 2018, and we’re happy to see plans materialise for its evolution.
To analyze huge amounts of data and enable machine learning for warfighting operations, CTI uses geo-visualization technologies like TAK and Raptor, software-defined radio applications GNU Radio and Redhawk, and Apache tools including Hadoop and Spark.
Development on GIMP fork Glimpse is on pause due to a lack of contributors able to support the image editor’s growing user base. More details in this post.
The DevOps Institute recently released their latest report entitled “Upskilling 2021: Enterprise DevOps Skills Report”. The report found that automation and security remain vital to business success. A focus on building the human skills of DevOps was also identified as companies with the best learning cultures were most likely to succeed.
If you want to learn Python you have plenty of options. Joining a MOOC, an online course where you work at you own pace, is a great choice but the cost could quickly mount up. This is where Coursera Plus, Coursera’s subscription that provides access to around 90% of its courses, seems like a really good idea.
For certain monitoring tools like yCrash, you need to pass your application process ID as input. In this article, Ram Lakshmanan will guide you through how to find your Java application process ID in both Linux/Unix and Windows operating systems – simply follow these steps.
In this post, we are going to discuss how to find your Java application process ID quickly. For certain monitoring tools like yCrash, you need to pass your application process ID as input. If you want to look for a more detailed post with several different options to find your application’s process ID, you can refer to this blog post.
ACM, the Association for Computing Machinery, today announced the recipients of four prestigious technical awards. These leaders were selected by their peers for making contributions that extend the boundaries of research, advance industry, and lay the foundation for technologies that transform society.
Shyamnath Gollakota, University of Washington, is the recipient of the 2020 ACM Grace Murray Hopper Award for contributions to the use of wireless signals in creating novel applications, including battery-free communications, health monitoring, gesture recognition, and bio-based wireless sensing. His work has revolutionized and re-imagined what can be done using wireless systems and has a feel of technologies depicted in science fiction novels.
Gollakota defined the technology referred to today as ambient backscatter–a mechanism by which an unpowered, battery-less device can harvest existing wireless signals (such as broadcast TV or WiFi) in the environment for energy and use it to transmit encoded data. In addition, he has developed techniques that can use sonar signals from smartphones to support numerous healthcare applications. Examples include detection and diagnosis of breathing anomalies such as apnea, detection of ear infections, and even detection of life-threatening opioid overdoses. These innovations have the potential to transform the way healthcare systems will be designed and delivered in the future, and some of these efforts are now being commercialized for real-world use.
India’s deadly coronavirus second wave has underscored a stark digital divide determining who has better access to vaccines and healthcare, as surging caseloads expose shortfalls and overwhelm hospitals.
Onerous online procedures have turned vaccine access into an exclusionary, often lottery-like process in a country where about half the population lacks internet access.
When India opened up vaccines to all adults on 1 May, those in the 18 to 44 age group had to register through the Cowin platform – a centralised system – before they could book an appointment. For this, they need identity documents and access to a smartphone or computer with a strong internet connection. As states grapple with vaccine shortages, the online system has privileged a small fraction of elite, tech-literate city dwellers.
The research shows how access to nature in cities increases physical activity, and therefore, overall health.
Lack of physical activity in the US results in $117 billion a year in related health care costs and leads to 3.2 million deaths globally every year. It may seem like an intuitive connection, but the new research closes an important gap in understanding how building nature into cities can support overall human well-being.
Tech giant Microsoft recently announced the retirement of its longstanding web browser, Internet Explorer, in favour of its newer product, Microsoft Edge. With support for Internet Explorer only set to last until June 15, 2022, its remaining users have just over a year to find an alternative. But of course, most web users already have.
Since 2016, one of the biggest mysteries in tech circles was “What the heck was Google Fuchsia operating system?” A Linux replacement? A Google-specific Linux distribution? The end of Android? We eventually learned Fuchsia wasn’t Linux, but it might be a Linux replacement in some situations. At long last, we finally know. It’s, at least in its first version, an Internet of Things (IoT) operating system.
Security updates have been issued by Arch Linux (djvulibre, dotnet-runtime, dotnet-runtime-3.1, dotnet-sdk, dotnet-sdk-3.1, gupnp, hivex, lz4, matrix-synapse, prometheus, python-pydantic, runc, thunderbird, and websvn), Fedora (composer, moodle, and wordpress), Gentoo (bash, boost, busybox, containerd, curl, dnsmasq, ffmpeg, firejail, gnome-autoar, gptfdisk, icu, lcms, libX11, mariadb, mumble, mupdf, mutt, mysql, nettle, nextcloud-client, opensmtpd, openssh, openvpn, php, postgresql, prosody, rxvt-unicode, samba, screen, smarty, spamassassin, squid, stunnel, tar, tcpreplay, and telegram-desktop), openSUSE (Botan), Red Hat (kernel), Slackware (gnutls), SUSE (hivex, libu2f-host, and rubygem-actionpack-5_1), and Ubuntu (apport, exiv2, and libx11).
Merged today to Linux 5.13 Git and marked for back-porting to stable series is a new “confused deputy” weakness and affects kernels going back to Linux 2.6.12 from 2005.
Merged today is a proc code change to check writes against the file opener for the /proc/$pid/attr/ area where security attributes are handled for a given process.
TuxCare services from CloudLinux provide automated security patches and updates for the systems supporting the Atlas V rocket. Through this work, TuxCare supports Department of Defense and Space Force missions to protect U.S. National Security.
“Protecting U.S. national security means having the ability to launch important payloads into space. TuxCare from CloudLinux is proud to do our part to support the Department of Defense and the Space Force by providing critical security patches for ULA’s Atlas V rocket,” said Jim Jackson, president and CRO of CloudLinux.
Researchers at Trend Micro say about 50,000 IPs were compromised across multiple Kubernetes clusters in a wormlike attack by the cloud-focused cryptojacking group TeamTNT.
