Reiser5 Updates For Linux 5.5 Along With Reiser4

Filed under
Reiser

The out-of-tree Reiser4 and Reiser5 (Reiser4 v5) patches have been updated against the recently stabilized Linux 5.5 kernel.

Main Reiser4 developer Edward Shishkin re-based the Reiser4 file-system patch against Linux 5.5.1 along with the experimental Reiser5.

At the end of 2019 is when Shishkin announced Reiser5 file-system development with introducing the concepts of local volumes capable of parallel scaling out and other key iterations over the current Reiser4 design.

Reiser4 File-System Is Still Ticking In 2019 - Now Updated For Linux 5.3 Compatibility

Filed under
Linux
Reiser

Edward Shishkin continues near single-handedly maintaining the out-of-tree Reiser4 code that at this point still has no apparent trajectory towards mainline. The former Namesys developer previously indicated it's unlikely to see Reiser4 merged unless there is a company backing it to get it through the review process for merging into mainline. While Reiser4 was quite promising for its early time, it's only getting more difficult with Reiser4 effectively stagnating for years now while SUSE/openSUSE continues backing Btrfs, Ubuntu increasingly investing in ZFS support, Red Hat developing Stratis, XFS continuing to be advanced by Red Hat and others as well, Google continuing to invest in the likes of EXT4/F2FS, and there also being Bcachefs and other open-source storage solutions that are more promising than Reiser4 in 2019. Nevertheless, the out-of-tree kernel patches continue to be updated.

Reiser4 Brought To The Linux 5.0 Kernel

Filed under
Reiser

For those still using the out-of-tree Reiser4 file-system, it may be about time to consider alternatives like Btrfs, XFS, ZFS On Linux, F2FS, or even the likes of Stratis and Bcachefs. But should you still be using this once promising file-system, the out-of-tree patches have been revised to now work with the Linux 5.0 kernel.

There still is no trajectory for Reiser4 to the mainline Linux kernel with no major companies or other stakeholders backing Reiser4 but just a small group of developers and enthusiasts left working on this successor to ReiserFS. With the latest code posted on Friday by former Namesys developer Edward Shishkin, the Reiser4 kernel driver has been re-based to the Linux 5.0 kernel but with no other changes to the file-system noted.

Graphics/Benchmarks
Linux
Reiser

It's been about three years since last carrying out any file-system performance benchmarks of Reiser4, but being curious how it stacks up against the current state of today's mainline Linux file-systems, here are some fresh performance tests of Reiser4 using the Linux 4.17 kernel. The Reiser4 performance was compared to Reiserfs, EXT4, Btrfs, XFS, and F2FS.

Reiser4 Updated For Linux 4.14 & Introduces Zstd Compression Support

Filed under
Reiser

The out-of-tree Reiser4 file-system driver has been updated with compatibility for the latest Linux 4.14 stable series. Besides reworking the code to run on Linux 4.14, this controversial file-system has also added support for Zstd file-system compression.

Linux 4.14 introduced Zstd support in the mainline kernel and wired it in for SquashFS and Btrfs. Our Btrfs Zstd benchmarks have been promising for transparent file-system compression compared to the other supported algorithms. Reiser4 has now picked up Zstd compression as an eventual replacement to their Gzip compression support.

Reiser4 Updated For The Linux 4.10 Kernel

Filed under
Reiser

The out-of-tree Reiser4 file-system has been updated for the Linux 4.10 kernel.

Reiser4 for the Linux 4.10.0 kernel is available as of earlier this week, managing to release their updated file-system driver code quite promptly. This port to Linux 4.10 yielded a few changes to the Reiser4 code as they re-based to this Linux kernel with the ->readlink() of inode operations being removed as well as the WRITE_FLUSH_FUA flag being removed.

Reiser4 Is Now Available For Linux 4.9, Mirror Code Almost Stable

Filed under
Reiser

For those that haven't yet switched to Btrfs, ZFS On Linux, or running EXT4/XFS but holding out hope for Reiser4, this out-of-tree file-system code has been updated for Linux 4.9.

Reiser4 was released for Linux 4.9.0 last weekend but then a revised patch series came out three days ago to fix some problems with this port to 4.9. With the new Reiser4 patches built against Linux 4.9.1, all should be well if you want to use this experimental file-system on the newest Linux kernel.

Reiser4 Now Available For Linux 4.8 Kernel

Filed under
Reiser

While Linux 4.9 will be released in just a few weeks, the remaining Reiser4 file-system developers have just updated their code to support the Linux 4.8 stable kernel.

Reiser4 for Linux 4.8.0 is now available for those wanting to run this out-of-tree file-system on the current stable kernel. The Reiser4 kernel is now compatible with 4.8 and there is also a kernel oops fix when mounting forward-incompatible volumes, unneeded assertions were removed, some VFS changes were made, and there is now rename2 support.

Fedora’s gaggle of desktops

There are 38 different desktops or window managers in Fedora 31. You could try a different one every day for a month, and still have some left over. Some have very few features. Some have so many features they are called a desktop environment. This article can’t go into detail on each, but it’s interesting to see the whole list in one place. To be on this list, the desktop must show up on the desktop manager’s selection list. If the desktop has more than one entry in the desktop manager list, they are counted just as that one desktop. An example is “GNOME”, “GNOME Classic” and “GNOME (Wayland).” These all show up on the desktop manager list, but they are still just GNOME. Read more

Programming: 'DevOps', Caddyfile, GCC 8.4 RC and Forth

  • A beginner's guide to everything DevOps

    While there is no single definition, I consider DevOps to be a process framework that ensures collaboration between development and operations teams to deploy code to production environments faster in a repeatable and automated way. We will spend the rest of this article unpacking that statement. The word "DevOps" is an amalgamation of the words "development" and "operations." DevOps helps increase the speed of delivering applications and services. It allows organizations to serve their customers efficiently and become more competitive in the market. In simple terms, DevOps is an alignment between development and IT operations with better communication and collaboration. DevOps assumes a culture where collaboration among the development, operations, and business teams is considered a critical aspect of the journey. It's not solely about the tools, as DevOps in an organization creates continuous value for customers. Tools are one of its pillars, alongside people and processes. DevOps increases organizations' capability to deliver high-quality solutions at a swift pace. It automates all processes, from build to deployment, of an application or a product.

  • How to solve the DevOps vs. ITSM culture clash

    Since its advent, DevOps has been pitted against IT service management (ITSM) and its ITIL framework. Some say "ITIL is under siege," some ask you to choose sides, while others frame them as complementary. What is true is that both DevOps and ITSM have fans and detractors, and each method can influence software delivery and overall corporate culture.

  • JFrog Launches JFrog Multi-Cloud Universal DevOps Platform

    DevOps technology company JFrog has announced its new hybrid, multi-cloud, universal DevOps platform called the JFrog Platform that drives continuous software releases from any source to any destination. By delivering tools in an all-in-one solution, the JFrog Platform aims to empower organizations, developers and DevOps engineers to meet increased delivery requirements. For the uninitiated, JFrog is the creator of Artifactory, the heart of the Universal DevOps platform for automating, managing, securing, distributing, and monitoring all types of technologies.

  • New Caddyfile and more

    The new Caddyfile enables experimental HTTP3 support. Also I’ve added a few redirects to my new domain. All www prefix requests get redirected to their version without www prefix. My old domain nullday.de redirects now to my new domain shibumi.dev. Also I had to add connect-src 'self' to my CSP, because Google Lighthouse seems to have problems with defalt-src 'none'. If just default-src 'none' is being set, Google Lighthouse can’t access your robot.txt. This seems to be an issue in the Google Lighthouse implementation, the Google Search Bot is not affected.

  • Content Addressed Vocabulary

    How can systems communicate and share meaning? Communication within systems is preceded by a form of meta-communication; we must have a sense that we mean the same things by the terms we use before we can even use them. This is challenging enough for humans who must share meaning, but we can resolve ambiguities with context clues from a surrounding narrative. Machines, in general, need a context more explicitly laid out for them, with as little ambiguity as possible. Standards authors of open-world systems have long struggled with such systems and have come up with some reasonable systems; unfortunately these also suffer from several pitfalls. With minimal (or sometimes none at all) adjustment to our tooling, I propose a change in how we manage ontologies.

  • Excellent Free Tutorials to Learn Forth

    Forth is an imperative stack-based programming language, and a member of the class of extensible interactive languages. It was created by Charles Moore in 1970 to control telescopes in observatories using small computers. Because of its roots, Forth stresses efficiency, compactness, flexible and efficient hardware/software interaction. Forth has a number of properties that contrast it from many other programming languages. In particular, Forth has no inherent keywords and is extensible. It is both a low level and high level language. It has the interesting property of being able to compile itself into a new compiler, debug itself and to experiment in real time as the system is built. Forth is an extremely flexible language, with high portability, compact source and object code, and a language that is easy to learn, program and debug. It has an incremental compiler, an interpreter and a very fast edit-compile-test cycle. Forth uses a stack to pass data between words, and it uses the raw memory for more permanent storage. It also lets coders write their own control structures. Forth has often being deployed in embedded systems due to the compactness of object code. Forth is also used in boot loaders such as Open Firmware (developed by Sun Microsystems) as well as scientific fields such as astronomy, mathematics, oceanography and electrical engineering.

  • Adding Metadata to PDFs

    For both Django Crash Course and the forthcoming Two Scoops of Django 3.x, we're using a new process to render the PDFs. Unfortunately, until just a few days ago that process didn't include the cover. Instead, covers were inserted manually using Adobe Acrobat. [...] The lesson I learned writing this little utility is that as useful as Google and Stack Overflow might be, sometimes you need to explore reference manuals. Which, if you ask me, is a lot of fun. :-)

  • A Week At A Time - Building SaaS #46

    In this episode, we worked on a weekly view for the Django app. We made navigation that would let users click from one week to the next, then fixed up the view to pull time from that particular week. The first thing that I did was focus on the UI required to navigate to a new weekly view in the app. We mocked out the UI and talked briefly about the flexbox layout that is available to modern browsers. From the UI mock up, I changed the view code to include a previous_week_date and next_week_date in the view context so we could change the links to show real dates. From there, we needed a destination URL. I create a new path in the URLconf that connected the weekly URL to the existing app view that shows the week data. After wiring things together, I was able to extract the week date from the URL and make the view pull from the specified day and show that in the UI. Finally, we chatted about the tricky offset calculation that needs to happen to pull the right course tasks, but I ended the stream at that stage because the logic changes for that problem are tedious and very specific to my particular app.
