Stay Protected with Librem 14’s Latest Pureboot Feature

Filed under

The Librem 14 Pureboot bundle is pushing the envelope on security tools. Newly added to our latest PureBoot release is a feature that protects against file changes on your root filesystem. This is the same validation done on the boot partition, simply expanded to specified directories on the root filesystem. This allows you to cryptographically sign your OS files with keys in your control.

These Mockups of System76’s Cosmic Desktop Leave Me Very Excited

Filed under

If last weeks sneak peek at real-world progress on System76’s new Rust-based desktop experience left you excited, just wait until you see what they’ve got planned next.

Pop!_OS code explorer Eduardo Flores dug up a Figma design document made by System76 gives us a much better look at what’s in store for the next-gen COSMIC desktop environment.

And though hate to be a tease: it looks amazing.

Now, I’ve always been a fan of desktop applets, indicators, menu bar items, whatever you want to call then. Vanilla GNOME is pretty averse to them and its Status Menu ‘groups’ several functions into one menu. While there are extensions out there that can split them back out, it’s not the defeat.

  • Fedora Server 36 Could Make It Easier To Manage NFS & Samba File Sharing - Phoronix

    Red Hat with the Fedora community have been working for years now to make Cockpit very capable for a web-based interface for administering Linux servers. In addition to this year working on shifting their Anaconda installer to a web-based interface that makes use of Cockpit, from this web management portal they are wanting to make it easier to setup file sharing with NFS and Samba.

    A Fedora 36 change proposal has been submitted to ship a new Cockpit module to make file sharing with Samba and NFS easier. This new module would provide a graphical web interface for provisioning and maintenance of NFS and Samba shares that can complement the existing command-line based controls for NFS and Samba servers.

  • I'm Thinking About You Right Now!

    My sole role at Debian alongside my teammate, aided by our mentors, is to facilitate the Node.js 16 and Webpack 5 Transitioning. What exactly does that mean?

    Node.js 16, as of the time of this writing, is the active LTS release from the Node.js developers while Webpack 5 is also the current release from the Webpack developers. At Debian we have to work towards supporting these packages. Debian as an OS comes with a package manager coined Advanced Package Tool or simply APT on which command-line programs specific to Debian and it's many-flavored distributions, apt, apt-get, apt-cache are based. This means before the conception of yarn and npm, the typical JavaScript developer's package managers, apt has been. Debian unlike yarn and npm, ideally only supports one version of a software at any point in time and on edge cases may have to support an extra one as noted in this chat between my mentor and a member.

  • On DEI Research: Why the Linux Foundation? Why now? [Ed: Linux Foundation may struggle to justify its very own existence]

    The open source community is working on many simultaneous challenges, not the least of which is addressing vulnerabilities in the core of our projects, securing the software supply chain, and protecting it from threat actors. At the same time, community health is equally as important as the security and vitality of software code.

    We need to retain talented people to work on complex problems. While we work urgently on implementing security best practices such as increasing SBOM adoption to avoid another Log4J scenario, we can’t put the health of our communities on the open source back burner, either.

    Our communities are ultimately made up of people who contribute, have wants and needs, and have feelings and aspirations. So while having actionable data and metrics on the technical aspects of open source projects is key to understanding how they evolve and mature, the human experience within project communities also requires close examination.

    The long time Phoronix reader, with an excellent long-term memory, may remember an odd article from back in August 2017 on buying a passively cooled computer. It tells the tale of the consumer who decided to buy a rather niche, fanless, therefore passively cooled computer.

    Well, that was been my computer for four and a half years. Even though the I7-7700T the article portrayed has served me well. It did start to show age a little. Especially as of late, it will sometimes spontaneously reboot. It does so very rarely, without prior warning and seemingly unprovoked. Its a bit of a nuisance.

  • AMD Preps for Zen 4: Different Types of Cores Now Supported in Linux | Tom's Hardware

    Perhaps, a more intriguing innovation is a new Scalable Machine Check Architecture (SMCA) of some future AMD platforms that could use different types of SMCA and therefore cores.

    "Future AMD systems will have different bank type layouts between logical CPUs," wrote Yazen Ghannam, an AMD engineer. "So having a single system-wide cache of the layout won't be correct. […] Patch 1 adds new bank types and error descriptions used in future AMD systems. Patch 2 adjusts how SMCA bank information is cached."

    So far, AMD has not announced a single hybrid processor that integrates different types of cores, though the company has never completely excluded such a possibility. Since AMD will have Zen 4 and Zen 4C cores next year, perhaps this is the time when the company might consider a CPU with both big and smaller cores. Alternatively, a new SMCA may indicate that Zen 4C will have a different machine check architecture than other Zen cores, which is why AMD needs to implement its support into Linux.

  • Zink 4ever

    After weeks of hunting for the latest rumors of jekstrand’s future job prospects, I’ve finally done it: zink now supports more extensions than any other OpenGL driver in Mesa.

    That’s right.

    Check it on mesamatrix if you don’t believe me.

    A couple days ago I merged support for the external memory extensions that I’d been putting off, and today we got sparse textures thanks to Qiang Yu at AMD doing 99% of the work to plumb the extensions through the rest of Mesa.

    There’s even another sparse texture extension, which I’ve already landed all the support for in zink, that should be enabled for the upcoming release.

  • Zink OpenGL-on-Vulkan Now Offers Broader OpenGL Coverage Than RadeonSI, Intel - Phoronix

    When it comes to OpenGL extension support, the Zink generic OpenGL-on-Vulkan implementation now has as robust coverage as core Mesa offers and what is implemented by the LLVMpipe software driver, RadeonSI Gallium3D, and the Intel i965 drivers.

    Zink has already offered OpenGL 4.6 support but now after recently adding some additional extensions that aren't mandated by version 4.6, it is now on-par with the other drivers for the raw number of extensions exposed and exceeds the other drivers for non-core extensions.

    Zink along with core Mesa / LLVMpipe / RadeonSI / i965 are at 160 extensions exposed while being the set of open-source drivers supporting OpenGL 4.6.

Collectd gathers metrics from various sources, e.g. the operating system, applications, log files and external devices, and stores this information or makes it available over the network. Those statistics can be used to monitor systems, find performance bottlenecks (i.e. performance analysis) and predict future system load (i.e. capacity planning). Or if you just want pretty graphs of your private server and are fed up with some homegrown solution you’re at the right place, too.

  • How to Setup Central Logging Server with Rsyslog in Ubuntu 20.04 – Citizix

    Rsyslog is an open-source software utility used on UNIX and Unix-like computer systems for forwarding log messages in an IP network. It is an open-source utility for log processing. It permits the logging of data from different types of systems in a central repository. Rsyslog is a Syslog protocol with more extensions, features, and benefits.

    Rsyslog can deliver over one million messages per second to local destinations when limited processing is applied making it so powerful. By default, Linux uses the syslog daemon to record logs about how the system is running and then putting these logs into a central repository in: /var/log where we can examine and investigate them.
    In simple terms of meaning everything from kernel events to user actions is logged by Linux, allowing you to see al most any action performed on your pc or servers.

Microsoft's Pluton will be shut off by default

Filed under

PCs coming this year with Microsoft's integrated Pluton security chip won't be locked down to Windows 11, and users will have the option to install Linux and turn off the feature completely.

The first PCs with Pluton chips and Windows 11 PCs were shown at CES earlier this month. Major PC chip makers, including Intel, AMD and Qualcomm are embedding the Pluton processor inside processors as a secure hardware layer to protect PCs.

But Microsoft's invasion at the hardware level has some users - especially in the open-source community - on high alert. The concern relates to the chip being a proprietary backdoor for Microsoft to take control of PCs and tying the hardware closely to Windows 11.

AMD integrated Microsoft's Pluton in Ryzen 6000 chips, which were introduced at CES earlier this month. AMD's goal is to bring better security to PCs, but users can disable Pluton.

"AMD respects user choice and, as is typical with many other security technologies, we provide the ability for a user to enable or disable Pluton based on their preferences in our reference BIOS," an AMD spokeswoman told The Register.

Pluton is a Windows security technology, but it does not restrict Linux installation, the spokeswoman said.

    The price for software security and maintainer burnout

    2022 started reminding us that software security is a problem not only for open source packages. At the same time, “how to remunerate open source maintainers?” is a question with impossibly numerous answers: we need focus to find different solutions for different problems.

    Lots of security issues packed in a few weeks: December 2021 saw the Log4j package knocked down by a nasty bug. In January 2022 we witnessed an act of self-sabotation by a maintainer of two NPM packages. On New Year's Day a bug in Microsoft Exchange ruined the celebrations for many system administrators. Very different scenarios that confirm how complex and fragile our IT infrastructure is. With open source software so popular, shipped in millions of software packages, the open source communities risk becoming a punching bag for problems it cannot necessarily solve.

  • Home Assistant Yellow - Pi-powered local automation

    For example, I wanted to make it easy for my kids to control a home theater with four different devices and complex audio/visual routing, so I bought a Harmony remote and programmed it to control TV, a game console, an Apple TV, and radio. I don't want Logitech to start controlling other aspects of my house, or to give intruders an avenue by which they could invade my home's network.

  • 6 ways financial services leaders can enable innovation | The Enterprisers Project

    Innovation is key to any organization’s future success, but it’s especially true for financial services organizations. So why isn’t innovation happening faster? Is your firm at risk of being left behind?

    In the mid-2000s, I sat at a lunch-and-learn with an executive from a major social platform, who was asked about an up-and-coming competitor. The response was, in my opinion, short-sighted; it went something like this: “We aren’t concerned about them; it’s for college kids and people have profiles, photos, and big networks of friends on our site. They won’t want to start over somewhere else.”

    The executive was wrong about this – very, very wrong. The financial services industry is at a similar tipping point and technology-based innovation will lead the way.

    What advice would you give to business leaders in working with their technical leaders?
    What can you do about it? Ask yourself: Are your business leaders and technical leaders slowing you down? Is collaboration too hard? Is alignment out of sync? We often hear frustrations from Red Hat clients about just getting things done and hear statements such as “Why can’t IT just get me what I need?” or “The business team doesn’t listen.”

    We asked former financial services IT pros who now work for Red Hat for tips on how business leaders in financial services can work better with IT leaders – and get their needs met more quickly.

  • 8 fundamental Linux file-management commands for new users | Enable Sysadmin

    I'm a believer in the basics, and as a former technical instructor, I have a soft spot for folks who are new to Linux (and other platforms). I've written articles on the fundamentals, and I thought it was time to cover some basic file-manipulation commands.

    This article looks at day-to-day tasks such as copying, moving, renaming, creating, and deleting files and directories. Here are eight commands to make managing files easier.

  • Building better businesses: Announcing our Red Hat EMEA Digital Leaders 2021

    Life moves fast. Innovation moves faster. We’re all in a rush to keep up. Every now and then, it’s important to hit the pause button and reflect on achievements. Reflection isn’t just good for the soul. The accomplishments of others can be the gateway to our own progress. By taking inspiration and learnings from others, we can overcome organizational groupthink, draw on a more diverse pool of ideas and experiences, and shortcut our way to solutions and success.

    This is the thinking behind the Red Hat EMEA Digital Leaders Awards—a new program in association with Intel and IDC celebrating the best open source projects using Red Hat technology and services

    We received so many strong stories, from so many different countries and industries. When businesses apply open source solutions and working principles to their transformation projects, every KPI—profitability, cost savings, customer satisfaction, employee productivity and market share—is improved.

    It has been inspiring, and humbling, to see how Red Hat is helping to build better businesses, and a better world.

  • Integrate ISO 20022 payments messaging with CI/CD

    The financial industry is increasingly embracing International Organization for Standardization (ISO) 20022-based standards (MX messaging) to exchange messages for both payments and securities. Key benefits of MX messaging include its ability to capture richer data, flexibility, and machine-readable format. However, the older SWIFT MT message set is still deeply entrenched in the core systems and processes of the financial sector. This situation has created a growing demand for MT-MX conversion.

    In this article, I will show you one way to achieve MT to MX mapping on Red Hat OpenShift using the message transformation platform from Trace Financial, a Red Hat Independent Software Vendor (ISV), and Red Hat Fuse.

  • Fedora Community Blog: Outreachy Project “Mote” progress update

    I had heard Outreachy internship from one of my seniors who was sharing her experience in my college when I was in my second year. I decided to give it a shot with utmost dedication and learning after understanding how Outreachy can be a great learning experience – needed to excel in the IT industry. Outreachy helps people from under-represented groups and is a life-changing experience for a contributor. I feel happy now that I am working with amazing mentors who guide and motivate me at every step. This opportunity wouldn’t be possible without the support of my parents, friends, and mentors.
    I always have shared my knowledge and experience with beginners, and this is a chance for me to prove myself capable and then help other people contribute to Open Source. I am excited for the next 3 months of knowing community members and helping with the project.

    I am currently in week 5 of my Outreachy Internship and I must say it’s going great. Every day is a new learning experience for me with lots of new implementations, goals, and tasks. This keeps me motivated and afresh with the project.

  • Genode OS Planning For WireGuard, Mobile Usability With The PinePhone - Phoronix

    I've been writing about Genode OS for over a decade as one of the interesting original, open-source operating system frameworks that has taken novel approaches to many design elements and continues persevering with their efforts. For 2022 the project has yet more ambitious goals ahead.

    Over the course of 2021, Genode accomplished making use of more Linux driver code where possible, hardware-accelerated graphics are in better shape, and getting more code natively working on the platform such as the open-source Chromium web browser. Besides the Intel graphics in working shape, Genode OS also tackled web camera support, LTE data support, and other features in 2021.

  • Omicron Storm Cancels In-person ‘Spacewalk’ Event – Online Version Rescheduled

    With the Omicron variant of Covid-19 spreading across the country (and globe) like a fast moving storm, the folks at All Things Open have had to rethink their plans for presenting their free Spacewalk event as both an in-person and online hybrid event, and will now be offering the event online only.

    This led to some logistical difficulties for the event’s planners, since the original plan had been to livestream the event as it happened from the the Carolina Theater in downtown Durham, North Carolina. Long story short: the event originally scheduled for yesterday will now take place on Tuesday, January 25 at noon Eastern Time. Attendance is absolutely free, but a Zoom registration is required.

  • C your data structures with rellic-headergen

    Have you ever wondered how a compiler sees your data structures? Compiler Explorer may help you understand the relation between the source code and machine code, but it doesn’t provide as much support when it comes to the layout of your data. You might have heard about padding, alignment, and “plain old data types.” Perhaps you’ve even dabbled in emulating inheritance in C by embedding one structure in another. But could you guess the exact memory layout of all these types, without looking at the ABI reference for your platform or the source for your standard library?

  • DocKnot 7.01

    Continuing to flush out bugs in the recent changes to my static web site generator.

    I had missed some Unicode implications for how output from external programs was handled, and also missed Unicode decoding of the output from Pod::Thread, since Pod::Simple always encodes its output even if that output is to a scalar. I also missed an implication for how symlinks were handled in Path::Iterator::Rule, causing docknot spin to fail to copy files into the output tree that were symlinks in the input tree. Both of those bugs are fixed in this release.

  • The Rust Programming Language Blog: Security advisory for the standard library (CVE-2022-21658)

    The Rust Security Response WG was notified that the std::fs::remove_dir_all standard library function is vulnerable a race condition enabling symlink following (CWE-363). An attacker could use this security issue to trick a privileged program into deleting files and directories the attacker couldn't otherwise access or delete.

    This issue has been assigned CVE-2022-21658.
