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.

VokoscreenNG: Open Source Screencasting Tool

Filed under
OSS

Vokoscreen was one of the best screen recording software for Linux. Despite its rather ‘outdated looking’ interface, it had a decent userbase.

For some time, vokoscreen didn’t see updates and eventually it was discontinued.

The good news is that vokoscreen is not entirely dead. It’s reborn as vokoscreenNG.

The NG in vokoscreenNG stands for New Generation and rightly so because it’s been created from scratch using Qt and Gstreamer.

Who cares about Emacs?

Filed under
GNU

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.

  • 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.

  • 3D-Printed 3D Scanner made to work with your phone

    An Arduino-based 3D scanner was created by an industrious 3D printing enthusiast and released open source this week for all to enjoy. This open source project was made to take out the most time-consuming component of the 3D scan process, giving said process instead to an Android phone combined with 3D-printed parts, a cheap motor, and an Arduino. This is not the first time such a system has been attempted, but it does appear to be the most complete and ready-to-roll system to date.

  • All Those Low-Cost Satellites in Orbit Could Be Weaponized by Hackers, Warns Expert

    Last month, SpaceX became the operator of the world's largest active satellite constellation. As of the end of January, the company had 242 satellites orbiting the planet with plans to launch 42,000 over the next decade.

    This is part of its ambitious project to provide internet access across the globe. The race to put satellites in space is on, with Amazon, UK-based OneWeb and other companies chomping at the bit to place thousands of satellites in orbit in the coming months.

  • NMap - A Basic Security Audit of Exposed Ports and Services

    For a plethora of reasons, auditing the security of our servers and networks is of paramount importance. Whether we are talking about a development server, a workstation, or a major enterprise application, security should be baked into every step of the deployment. While we can easily check our firewall settings from “the inside” of our systems. It is also a good idea to run a security audit from "the outside”. Using a network enumeration tool such as the famous and highly vetted Network Mapper (NMap).

  • Cybersecurity startup Polyverse raises $8M to protect Linux open-source code from hackers [Ed: Right around the corner from Bill Gates, another company like Black Duck and it'll "protect" Linux... just buy its proprietary software]

    Polyverse has been validated by the U.S. Department of Defense for mitigating zero-day attacks, intrusions that occur just as a vulnerability becomes public, such as the infamous WannaCry ransomware and hacks of companies like Equifax. The company says its technology is “running on millions of servers.”

  • MongoDB: developer distraction dents DevSecOps dreams

    MongoDB’s director of developer relations has just opened a piece of internal research that suggests as few as 29% of Europe’s developers take full responsibility for security.

    Now, 29% is a somewhat arbitrary figure, cleary i.e. it could be 22.45% or it could be 39.93%… the fact that the firm has pointed to an exact sum in this way is merely intended to show that it has undertaken a degree of calculation and statistical analysis

  • NGINX Unit Adds Support for Reverse Proxying and Address-Based Routing

    NGINX announced the release of versions 1.13 and 1.14 of NGINX Unit, its open-source web and application server. These releases include support for reverse proxying and address-based routing based on the connected client's IP address and the target address of the request.

    NGINX Unit is able to run web applications in multiple language versions simultaneously. Languages supported include Go, Perl, PHP, Python, Node.JS, Java, and Ruby. The server does not rely on a static configuration file, instead allowing for configuration via a REST API using JSON. Configuration is stored in memory allowing for changes to happen without a restart.

  • Kubernetes Security Plagued by Human Error, Misconfigs

    Following a year of numerous security bugs within the Kubernetes ecosystem and the first security audit of Kubernetes conducted by the Cloud Native Computing Foundation (CNCF), which hosts the open source platform, continued wide-spread adoption has seen security become somewhat of an afterthought.

    However, if security concerns continue inhibiting business innovation, does that fall on businesses for neglecting security practices or the market for not providing them with the tools to confidently secure their deployments?

    “People just get security wrong sometimes,” McLean said. “Companies need a combination of increased learning, cross-pollination, new tooling, and updated processes to identify and remediate these security ‘mistakes’ during build and deploy vs. waiting for exposure during runtime.”

  • Sectors Realizing the Full Potential of DeFi Protocols In 2020

    As the new decade unreels, a new wave of disruption seems to be coming to the shores of the global financial system. That wave is called decentralized finance protocols.

    Decentralized finance, or DeFi, simply refers to financial software that is built on the blockchain to make it easy for anyone to piece together digital assets and financial smart contracts.

  • Infographic: Who Has Funded Bitcoin Core Development?

    Monetarily, free and open-source software (FOSS) has always been at a disadvantage to proprietary software. It’s easier to solicit funding for a centralized project than for a decentralized one, not least of all because companies necessitate business models.

    Conversely, funding (and the agendas that often come with it) seems almost anathema to FOSS projects. At the very least, it is elusive. And Bitcoin is no exception.

  • You can now own a mobile phone with a rotary dial — if that’s really something you want

    While some would be quite literally lost without theirs, smartphones that give us access to a world of information in our pocket but constantly ask to be pulled out of there and stared at have become so complicated many people now find them annoying.
    This has triggered the rise of “dumbphones”, which look like the mobile phones of the past while still having some modern technologies.
    These devices range from the quite cheap to the weirdly expensive.
    Some customers opt for these phones to disconnect from the always online world – while others merely want to be seen to be doing so.
    But if you’re looking for the ultimate disconnected phone, one tinkerer has the perfect device.
    Justine Haupt is an associate scientist at the Brookhaven National Laboratory in New York.
    She’s also the creator of the open source Rotary Cellphone, a mobile phone with a tactile spinning dial like the kind that was common on house phones until around the 1980s.

  • Rotary Cellphone
  • Open-source rotary cellphone

    Justine Haupt made this handsome and completely functional rotary cellphone. Her design is open-source and you can even buy a case kit from her company, Sky's Edge Robotics. You have to find and carefully modify your own rotary dial, though -- they're apparently no longer made -- as well as a few other components.

Games: GNU/Linux Gaming, Aseprite and Corona to Release Code

Filed under
Gaming
  • What have you been playing recently and what do you think about it?

    It's been quite some time since we last had an open discussion about what you've all been playing recently. Let's get things going again.

    We've almost finished the second month of 2020, we've had tons of Linux games that have released this year already and a huge amount more on the way. Now with the rise of game streaming, Steam Play Proton and more options appearing constantly there's never a shortage of gaming to be had.

  • Check out 'Aseprite' a popular cross-platform pixel-art tool to create 2D animations and sprites

    Although I'm not into game development, after finding about this popular 2D pixel animation program while researching something else, I decided to cover it here on GOL in the hopes that someone finds it useful or time saving. Aseprite is a tool developed by small Argentine developer Igara Studio, that has been around in some form for almost two decades, having its version 1.0 released on Jun 6, 2014. Right now on Steam it has 2897 positive reviews by Steam users, out of 2923 total reviews, reaching as a consequence an 'Overwhelmingly Positive' status.

    According to Corona Labs’ official website, the company will cease operations on May 1. The decision to close the company was made by its owner, monetization platform Appodeal, as the business’ operating expenses exceeded its revenue.

    Game developers will still have access to the Corona engine, and all projects created on it will continue to work. The project itself will now be distributed under a new, simplified license. It involves the unrestricted distribution of apps and games created on Corona.

Reaching Serenity: Porting Git To A Homebrew Operating System

Filed under

Development

Life is all about the little joys — such as waking up in the morning and realizing there’s still plenty of time before you have to actually get up. Or getting up anyway to watch a delightful sunrise as the city slowly wakes up, or as [Andreas Kling] chose, porting your favorite development tool to the operating system you wrote.

With the aesthetics of ’90s UI design and the functionality of a simpler 2000s Unix-style system core in mind, and personal reasons to keep himself busy, [Andreas] started SerenityOS a little while back. Of course, writing your own operating system is always a great educational exercise, but it takes a certain amount of commitment to push it beyond an experimental playground phase. So ideally, you’d eventually want to use it as your actual main system, however, as software developer, [Andreas] was missing one crucial component for that: git. Well, he decided to change that and just port it — and as someone who likes to record his hacking sessions, you can watch him along the way.

Android
  • An /e/ phone in 2020

    The /e/ phone does not offer all the apps Android does, and it might not be entirely polished yet in the re-branding experience. However, it does provide a very solid, mostly Android compatible experience without the Google bits. The /e/ team offers a wider range of hardware support than most other iOS and Android competitors, it offers most of the popular Android apps people will probably want to use (I only discovered a few missing items I wanted), and the on-line cloud services are better than those of any other phone I’ve used (including Ubuntu One and Google).

    I’d certainly recommend /e/ for more technical users who can work around minor rough edges and who won’t get confused by the unusual branding and semi-frequent permission prompts. I’m not sure if I’d hand one of these phones over to an Android power-user who uses a lot of niche apps, but this phone would certainly do well in the hands of, for instance, my parents or other users who tend to interact with their phones for texting, phone calls, and the calendar without using many exotic applications.

  • A 'Pixel 5' mention spotted in the Android Open Source Project (AOSP) comments

    While Google usually announces its flagship devices in October of every year, leaks and rumors of the devices begin showing up in the months leading to the launch. Details of the next-generation Pixels, however, seem to have begun leaking much earlier as there have been reports of the camera placement on Google’s upcoming flagship. Now, mentions of the “Pixel 5” in the Android Open Source Project (AOSP) code comments somewhat confirm the name and existence of such a device.

    The comment on a code change for the Linux kernel mentions the “Pixel 5 with (version) 4.19”, confirming the existence of a device running version 4.19 of the Linux kernel. Reports of a device running Linux kernel version 4.19 and named “bramble” have also been previously spotted. Codenames of upcoming Pixel devices leaked last month, bearing the names “redfin”, “sunfish”, and bramble” and at least one of those devices is believed to be the mid-range Pixel 4a.

  • Google Pixel 5 make appearance in Android Open Source Project

    Over the past few weeks, we have been seeing the leaks and rumors surrounding Google’s upcoming Pixel 4a smartphone. And now, details about the Pixel 5 flagship device have also surfaced. Just recently, the alleged design of the Google Pixel 5 XL leaked online.

    Now, Google’s next flagship has also leaked in its name. It turns out that Pixel 5 is already in the works within the Android Open Source Project (AOSP) code. The leak comes from a new code change for the Linux kernel of Android, where developer Elena Petrova – of AOSP – explains that it has only been tested in Pixel 4 and not in any new device.

  • Google ‘Pixel 5’ makes its first appearance in Android Open Source Project

    We now have potential confirmation from AOSP code comments that Google’s next mainline Pixel phone will, unsurprisingly, bear the name “Pixel 5.” The confirmation comes from a new code change for Android’s Linux kernel, which the AOSP developer explains has only been tested on the Pixel 4 and not the Pixel 5.

  • Pixel 5 surfaces in Android Open Source Project, hints at mid-range chip

    We’ve already seen an alleged render of the upcoming Google flagship, and possible codenames for the Pixel 5 and 5 XL — Redfin and Bramble — have turned up. Now, a code change submitted to the Android Open Source Project (AOSP) contained comments that directly mention the Pixel 5.

    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.

Review: Void 20191109

Filed under
Reviews

Void is a rolling release Linux distribution. The project offers a number of features which are uncommon in the Linux community, including a custom package manager (XBPS), two flavours of C library (the GNU C Library, glibc, and musl libc), and a custom init implementation called runit. If this were not enough to make the project interesting, the distribution can run on multiple architectures, including 32-bit (x86), 64-bit (x86_64), and several ARM boards, including the Raspberry Pi and BeagleBone.

Void is also the future base for Project Trident, which is migrating from TrueOS to Void, partially for more up to date hardware support. The Void project is available in a minimal, command line edition and six desktop editions: Enlightenment, Cinnamon, LXDE, LXQt, MATE, and Xfce. This, along with each edition being available in two C library flavours and multiple CPU architectures means the hardest part when getting started with Void is picking which option to download. I went with the 64-bit Xfce edition with the musl library. This edition was 757MB in size.

Booting from the live media brings up a menu asking if we would like to load the live desktop or transfer the operating system into RAM for improved performance and then load the live desktop. Either way, in short order the Xfce 4.14 desktop appears. The desktop's panel with an application menu, task switcher, and system tray appears across the top edge of the screen. A quick-launch panel appears centred along the bottom of the screen. Immediately after the desktop loads a pop-up message appears letting us know "Xfce PolicyKit Agent" has encountered an error. No further information is provided and all we can do is close this window. This PolicyKit error appears every time we sign in, both when running the live environment and when the operating system has been installed on the hard drive.
