Excellent System Tools: nnn – portable terminal file manager

Filed under
GNU
Linux
Software

I’m devoting most of my spare time writing about the Raspberry Pi 4 (RPI4). My findings are captured in a weekly blog chronicling my experience of using the tiny machine as a desktop replacement. One of my forthcoming blog posts examines file managers on the RPI4 looking at both graphical and terminal-based file managers.

As I’ve spent a lot of time using nnn in the past few weeks, it makes sense I look at the latest release on a regular Intel machine, in advance of my RPI4 file manager blog.

LinuxLinks has previously reviewed imgp and googler. They are open source software coded by Arun Prakash Jana. He’s also the developer of nnn which has seen a new major release in the past fortnight. I’ve never reviewed any of Mr Jana’s software before.

How does the author describe his software? His man page says “nnn is the missing terminal file manager for X. (Nnn’s Not Noice) is a performance-optimized, feature-packed fork of noice with seamless desktop integration, simplified navigation, navigate-as-you-type mode with auto select, disk usage analyzer mode, bookmarks, contexts, application launcher, familiar navigation shortcuts, subshell spawning and much more. It remains a simple and efficient file manager that stays out of your way.”

In a single sentence, nnn can be probably best summarized as software seeking to bridge the gap between the terminal and the desktop environment.

Reiser5 in Linux 5.5.5 and C-SKY CPU Architecture for Linux 5.6

  • Reiser5 Spun Up For The Linux 5.5.5 Kernel

    For those that have been wanting to take the experimental Reiser5 for a test drive since being announced at the end of 2019, new versions of the Reiser4 and Reiser5 file-system kernel patches have been posted.

    Edward Shishkin who continues as the lone driving force behind Reiser4 and the new Reiser5 / Reiser4 v5 file-system has updated the out-of-tree file-system for the latest kernel release. These newest patches re-base Reiser4 and Reiser5 for Linux 5.5.5 as well as Linux 5.4.21. Recent VFS optimizations upstream were causing system lockups and other upstream changes necessitated another spin of these patches for the newest Linux kernel point releases.

Linux 5.6-rc3

Filed under
Linux

Fairly normal rc3 as far as I can tell. We've seen bigger, but we've
seen smaller ones too. Maybe this is slightly on the low side of
average at this time, which would make sense since this was a smaller
merge window. Anyway, too much noise in the signal to be sure either
way.

The overall stats look fairly regular too: about 55% drivers (staging,
sound, gpu, networking,  and usb look noticeable, with some noise
elsewhere). The bulk of the staging diff is actually the vsoc removal,
so that's nice.

Outside of drivers, we have the usual suspects: arch fixes (powerpc,
s390, x86, but also a late csky update that I couldn't find it in
myself to worry about). Filesystems (ext4 and btrfs) and networking.
And misc sprinkles of small fixes elsewhere.

See the appended shortlog for details,

Creating the same apps and software for different platforms is not an easy task for the developers. To make an app run on desktops, developers need to write a source code. However, to make the same app run on mobile devices, the developers have to write a different source code. With the new MauiKit, developers would be able to build convergent apps, that can run on both platforms with the same source code.

  • A Few More Linux Kernel Patches Floated This Week For AMD Family 19h (Zen 3)

    Going back to the start of 2020 we've been seeing a few patches here and there around AMD Family 19h, almost certainly Zen 3. That patch work has continued with a few more bits out this week while hopefully more bring-up is on the horizon ahead of the Linux 5.7 merge window opening in just over one month's time.

    Like the earlier Family 19h EDAC bring-up, this week's work isn't too juicy besides it being refreshing to see AMD punctually getting out Linux kernel patches for forthcoming hardware. The patches this week involve a few additions to AMD's perf subsystem code around the uncore bits. No enticing details of Family 19h are revealed but just shifting code around for supporting the L3 thread mask for the forthcoming CPUs and also the L3 PMU.

  • Broadcom Bringing Up Linux Support For VK Accelerators

    Broadcom developers have been recently volleying open-source Linux driver patches for enabling their "VK Accelerators" on the platform.

    Broadcom VK Accelerators are PCI Express offload engines for supporting video transcoding on multiple streams in parallel. These VK Accelerators offer various video offload processing features and are exposed to user-space via specialized /dev/bcm-vk.X devices. We haven't yet seen user-space patches to see if Broadcom intends to support any of the common APIs or will be developing their own customized solution.

    This Broadcom VK offload engine relies upon seemingly closed-source firmware files to be loaded for running the logic on these accelerators.

Who cares about Emacs?

GNU Emacs isn't the oldest interactive text editor for Unix—it's predated (at least) by the Vi editor—nor is it the only Emacs in existence. However, it's surely the most popular Emacs and one of the best editors available on POSIX. Or it was until fresh new editors, like Atom, VSCode, and Brackets, came to the fresh new open source landscape of today. There are so many options for robust text editors now, many of which have iterated upon Emacs' ideas and traditions, that you may well wonder whether GNU Emacs is still relevant. Read more

3-D Printing and Open Hardware: MakerBot, AAScan and RISC-V

  • MakerBot Targets Schools With Rebranded Printers

    MakerBot was poised to be one of the greatest success stories of the open source hardware movement. Founded on the shared knowledge of the RepRap community, they created the first practical desktop 3D printer aimed at consumers over a decade ago. But today, after being bought out by Stratasys and abandoning their open source roots, the company is all but completely absent in the market they helped to create. Cheaper and better printers, some of which built on that same RepRap lineage, have completely taken over in the consumer space; forcing MakerBot to refocus their efforts on professional and educational customers.
