Find lost files with Scalpel

Filed under

Software
HowTos

As a system administrator, part of your responsibility is to help users manage their data. One of the vital aspects of doing that is to ensure your organization has a good backup plan, and that your users either make their backups regularly, or else don’t have to because you’ve automated the process.

However, sometimes the worst happens. A file gets deleted by mistake, a filesystem becomes corrupt, or a partition gets lost, and for whatever reason, the backups don’t contain what you need.

As we discussed in How to prevent and recover from accidental file deletion in Linux, before trying to recover lost data, you must find out why the data is missing in the first place. It’s possible that a user has simply misplaced the file, or that there is a backup that the user isn’t aware of. But if a user has indeed removed a file with no backups, then you know you need to recover a deleted file. If a partition table has become scrambled, though, then the files aren’t really lost at all, and you might want to consider using TestDisk to recover the partition table, or the partition itself.

What happens if your file or partition recovery isn’t successful, or is only in part? Then it’s time for Scalpel. Scalpel performs file carving operations based on patterns describing unique file types. It looks for these patterns based on binary strings and regular expressions, and then extracts the file accordingly.

GNOME

In my slightly infamous email to fedora-devel I stated that I would turn off the snapd support in the gnome-software package for Fedora 31. A lot of people agreed with the technical reasons, but failed to understand the bigger picture and asked me to explain myself.

I wanted to tell a little, fictional, story:

In 2012 the ISO institute started working on a cross-vendor petrol reference vehicle to reduce the amount of R&D different companies had to do to build and sell a modern, and safe, saloon car.

Moz/FF

Earlier this week, Mozilla released version 68 of the Firefox web browser. Firefox is the default web browser in Fedora, and this update is now available in the official Fedora repositories.

This Firefox release provides a range of bug fixes and enhancements, including:

Better handling when using dark GTK themes (like Adwaita Dark). Previously, running a dark theme may have caused issues where user interface elements on a rendered webpage (like forms) are rendered in the dark theme, on a white background. Firefox 68 resolves these issues. Refer to these two Mozilla bugzilla tickets for more information.
The about:addons special page has two new features to keep you safer when installing extensions and themes in Firefox. First is the ability to report security and stability issues with addons directly in the about:addons page. Additionally, about:addons now has a list of secure and stable extensions and themes that have been vetted by the Recommended Extensions program.

Fedora: Google Code-in, Python and NeuroFedora

  • Fedora Community Blog: GCI 2018 mentor’s summit @ Google headquarters

    Google Code-in is a contest to introduce students (ages 13-17) to open source software development. Since 2010, 8,108 students from 107 countries have completed over 40,100 open source tasks Because Google Code-in is often the first experience many students have with open source, the contest is designed to make it easy for students to jump right in. I was one of the mentors in this first time for Fedora program. We had 125 students participating in Fedora and the top 3 students completed 26, 25 and 22 tasks each.

    Every year Google invites the Grand-Prize winners and their parents, and a mentor to it’s headquarters in San Francisco, California for a 4 days trip. I was offered the opportunity to go and represent Fedora in the summit and meet these 2 brilliant folks in person. This report covers activities and other things that happened there.

  • Fedora mulls its "python" version

    There is no doubt that the transition from Python 2 to Python 3 has been a difficult one, but Linux distributions have been particularly hard hit. For many people, that transition is largely over; Python 2 will be retired at the end of this year, at least by the core development team. But distributions will have to support Python 2 for quite a while after that. As part of any transition, the version that gets run from the python binary (or symbolic link) is something that needs to be worked out. Fedora is currently discussing what to do about that for Fedora 31.

    Fedora program manager Ben Cotton posted a proposal to make python invoke Python 3 in Fedora 31 to the Fedora devel mailing list. The proposal, titled "Python means Python 3", is also on the Fedora wiki. The idea is that wherever "python" is used it will refer to version 3, including when it is installed by DNF (i.e. dnf install python) or when Python packages are installed, so installing "python-requests" will install the Python 3 version of the Requests library. In addition, a wide array of associated tools (e.g. pip, pylint, idle, and flask) will also use the Python 3 versions.

    The "Requests" link above does point to a potential problem area, however. It shows that Requests for Python 3 III is not fully finished, with an expected release sometime "before PyCon 2020" (mid-April 2020), which is well after the expected October 2019 release of Fedora 31. The distribution already has a python3-requests package, though, so that will be picked up as python-requests in Fedora 31 if this proposal is adopted. There may be other packages out there where Python 3 support is not complete but, at this point, most of the major libraries have converted.

  • NeuroFedora poster at CNS*2019

  • Cockpit 198

    Cockpit has been restyled to match the PatternFly 4 User Interface design, including the Red Hat Text and Display fonts.

    This style refresh aligns Cockpit with other web user interfaces that use PatternFly, such as OpenShift 4.

    Over time, Cockpit will be ported to actually use PatternFly 4 widgets, but this restyle allows us to change Cockpit gradually.

  • The State Of EPEL-8 For Complementing RHEL8's Packages

    Under the Fedora umbrella has been the "Extra Packages for Enterprise Linux" to complement the official RHEL packages with extra packages largely based on Fedora packages. While RHEL 8.0 launched in May, there hasn't been full support for EPEL-8 yet but it's being worked on.

    Due to the many changes from RHEL7 to RHEL8, the EPEL-8 support has been slow. The EPEL-8 bring-up is being done via a multi-phase roll-out.

  • Fedora Community Action and Impact Coordinator (FCAIC)

    I’ve decided to move on from my role as the Fedora Community Action and Impact Coordinator (FCAIC). This was not an easy decision to make. I am proud of the work I have done in Fedora over the last three years and I think I have helped the community move past many challenges. I could NEVER have done all of this without the support and assistance of the community!

    As some of you know, I have been covering for some other roles in Red Hat for almost the last year. Some of these tasks have led to some opportunities to take my career in a different direction. I am going to remain at Red Hat and on the same team with the same manager, but with a slightly expanded scope of duties. I will no longer be day-to-day on Fedora and will instead be in a consultative role as a Community Architect at Large. This is a fancy way of saying that I will be tackling helping lots of projects with various issues while also working on some specific strategic objectives.

Canonical and IBM/Red Hat Strategy on Servers

Filed under

Server
Ubuntu
  • Inside the Canonical Container Strategy

    Canonical continues to pursue a somewhat bifurcated approach to containers by announcing support for Kubernetes 1.15 while continuing to advance Snaps as an application container that enables software deployment via a single click.

    For example, Canonical recently announced in collaboration with DJI that Snaps will be supported on an instance of Ubuntu embedded in Manifold 2 drones manufactured by DJI. While that approach will make it easier to deploy containerized applications on a type of embedded system, Snaps—for the moment, at least—mostly only runs on Ubuntu.

    Docker, in contrast, provides what Canonical describes as “process containers,” which typically are immutable and share some libraries across all containers in execution. Docker registries are optional and typically contain a loose collection of Docker images identifiable by hash or tags. That approach makes it possible to run containerized applications across multiple operating systems. However, within organizations that have standardized on Ubuntu, Canonical is making the case for an application container in the form of Snaps.

    Canonical is trying to drum up support for Snaps on multiple distributions of Linux with mixed success. Most recently, it made available Snapd, a service that individual developers can employ to run Snaps on other Linux distributions. Support for Snaps running on Linux distributions other than Ubuntu generally is limited to what’s provided by Canonical, which tends to limit enthusiasm. It’s also worth noting that alternative application packaging technologies in the form of AppImage and Flatpak have been around longer than Snaps.

  • Cloud Application Platform vs Container as a Service vs VM hosted application

    In the “old days,” applications were always hosted in a traditional way on a physical server or a group of physical servers. However, physical servers are expensive, hard to maintain and hard to grow and scale. That’s when virtual machines (VM) grew in popularity. VMs provided a better way to maintain, grow and scale. That is, they were easier to backup and restore and migrate from one region to another and they were easier to replicate across multiple domains/zones/regions.

  • Sysadmin vs SRE: What's the difference?

    In the IT world, there has always been a pull between generalist and specialist. The stereotypical sysadmin falls in the generalist category 99 times out of 100. The site reliability engineer (SRE) role is specialized, however, and grew out of the needs of one of the first companies to know real scale: Google. Ultimately, these two roles have the same goal for the applications whose infrastructure they operate: providing a good experience for the applications’ consumers. Yet, these roles have drastically different starting points.

  • Unlocking the true potential of hybrid cloud with Red Hat partners

    Today, we announced that IBM’s landmark acquisition of Red Hat has closed and shared our vision for how our two companies will move forward together.

    You’ve heard that IBM is committed to preserving Red Hat’s independence, neutrality, culture and industry partnerships, and that Red Hat’s unwavering commitment to open source remains unchanged.

    There is a key part of that statement I want to focus on—partnerships.

    IBM has made a significant investment to acquire Red Hat, and respects that Red Hat wouldn’t be Red Hat without our partner ecosystem. Partners open more doors for open source than we can alone and are vital to our success.

  • Red Hat and IBM: Accelerating the adoption of open source

    Today, IBM finalized its acquisition of Red Hat. Moving forward, Red Hat will operate as a distinct unit within IBM, and I couldn't be more excited—not only for what today represents in the history of two storied technology companies, but what it means for the future of the industry, for our customers, and for open source.

    Red Hat's acquisition by IBM represents an unparalleled milestone for open source itself. It signals validation of community-driven innovation and the value that open source brings to users.

  • IBM Closes Landmark Acquisition of Red Hat for $34 Billion; Defines Open, Hybrid Cloud Future

    IBM (NYSE:IBM) and Red Hat announced today that they have closed the transaction under which IBM acquired all of the issued and outstanding common shares of Red Hat for $190.00 per share in cash, representing a total equity value of approximately $34 billion.

    The acquisition redefines the cloud market for business. Red Hat’s open hybrid cloud technologies are now paired with the unmatched scale and depth of IBM’s innovation and industry expertise, and sales leadership in more than 175 countries. Together, IBM and Red Hat will accelerate innovation by offering a next-generation hybrid multicloud platform. Based on open source technologies, such as Linux and Kubernetes, the platform will allow businesses to securely deploy, run and manage data and applications on-premises and on private and multiple public clouds.

  • Q&A: IBM’s Landmark Acquisition of Red Hat

    Paul: Red Hat is an enterprise software company with an open source development model. A fundamental tenet of that model is that everything we do, from new practices that we learn to new technologies that we develop, goes back to the upstream community. By joining forces with IBM, our reach into customers will dramatically increase so we’ll be in a position to drive open enterprise technology a lot further. As for IBM, we’ve been partners for quite some time, but now existing IBM customers will have even more direct access to next-generation open source-based technologies that are at the cornerstone of hybrid cloud innovation.

  • Jim Whitehurst email to Red Hatters on Red Hat + IBM acquisition closing

    Last October, we announced our intention to join forces with IBM, with the aim of becoming the world’s top hybrid cloud provider. Since then, the promise IBM chairman, president, and CEO Ginni Rometty and I made has not changed. In fact, our commitment to that vision has grown - Red Hat will remain a distinct unit in IBM as we work to help customers deliver any app, anywhere, realizing the true value of the hybrid cloud. This morning, we can share that the most significant tech acquisition of 2019 has officially closed and we can now begin moving forward.

    We will be hosting an all-hands company meeting today (Tuesday, July 9) where you will hear from me, Ginni, Paul Cormier and IBM senior vice president of Cloud and Cognitive Software, Arvind Krishna. Details on logistics to follow; I hope you will join us.

    Since we announced the acquisition, I’ve been having conversations with our customers, partners, open source community members and more Red Hatters than I can count (I’ve been following memo-list as well!). What struck me most from those conversations was the passion. It’s passion not just for a company, but for what we do and how we do it—the open source way. That’s not going to change.

  • Brandeis University and Open Source Initiative to Launch New Educational Partnership.

    Brandeis University’s Graduate Professional Studies division (GPS) will partner with The Open Source Initiative® (OSI) to provide new educational offerings for the open source community, the university announced at OSCON 2019. As more companies start leveraging Open Source Software to reduce costs, decrease time to deployment and foster innovation, the organizations that have realized success as open source consumers are now extending their participation within open source communities as collaborators and contributors. This shift can create new challenges to traditional business processes and models, requiring dedicated policies, programs and personnel to ensure that the investments in open source projects produce the desired benefits while still aligning with the values of the open source communities. The Brandeis GPS-OSI partnership will help address the growing demand for expertise within organizations seeking to authentically collaborate with, and productively manage, open source resources. “Understanding how to assess, engage, and contribute to open source communities while also delivering value to your company is the next generation skill set employers are looking for,” said Patrick Masson, general manager of the Open Source Initiative. “We're thrilled to work with Brandeis to help continue the incredible growth of open source software and projects.”

    For several generations now of Intel graphics there have been the GuC/HuC firmware binaries while beginning with Icelake "Gen 11" graphics those binary blobs will be loaded by default.  Intel's GuC has been used for graphics workload scheduling while the HuC firmware provides some "media functions from the CPU to GPU" for different video codec functions and CPU-GPU synchronization among other abilities. 

  • ZFS On Linux Has Figured Out A Way To Restore SIMD Support On Linux 5.0+

    Those running ZFS On Linux (ZoL) on post-5.0 (and pre-5.0 supported LTS releases) have seen big performance hits to the ZFS encryption performance in particular. That came due to upstream breaking an interface used by ZFS On Linux and admittedly not caring about ZoL due to it being an out-of-tree user. But now several kernel releases later, a workaround has been devised.  Some Linux distributions have resorted to reverting the kernel patch that stopped exporting the kernel FPU begin/restore functions used by ZoL for tapping vector-based (SSE/AVX) algorithms. But now ZFS On Linux itself has figured out a solution to restore said SIMD support on these recent kernel releases.
