Getting started with Double Commander

Filed under

Double Commander is a free and open source dual pane file manager. It is an excellent file manager, especially for those who prefer a consistent file manager experience, while trying out different Linux desktop environments. This article assists you with getting Double Commander installed and configured on your Linux system.

Each desktop environment ships with its own file manager: Nautilus on Gnome, Dolphin on KDE, Thunar on XFCE, etc. Working in the file manager forms and integral part of my daily PC work flow. Therefore I do not enjoy being forced to switch to a different file manager, each time I try out a different desktop environment on Linux. Additionally, I really enjoy dual pane file managers. If you recognize yourself in these file manager preferences, then I can highly recommend giving Double Commander a try.

Alexander Koblov develops and maintains Double Commander and he selected the Lazarus IDE for programming Double Commander. Here is an appetizer of what Double Commander looks like, while I am writing this article:

  • Linux-Fu: Automation For Chrome And The Desktop By Matching Screenshots

    I will be the first to admit it. This is almost not — at least not specifically — a Linux article. The subject? An automation tool for Chrome or Firefox. But before you hit the back button, hear me out. Sure, this Chrome plugin started out as a tool to automatically test web pages and automate repetitive tasks in the browser. However, it can extend that power to all programs on your computer. So, in theory, you can use it to graphically build macros that can interact with desktop applications in surprisingly sophisticated ways. In theory, anyway; there are a few problems.

    The program has a few different names. Most documentation says UI Vision RPA, although there are some references to Kantu, which appears to be an older name. RPA is an acronym for Robotic Process Automation, which is an industry buzz word.

  • Transmission review

    Transmission is one of the rare torrent clients that comes with a solution for embedded hardware like NAS and home servers. It is free, open source, and offers impressively fast performance levels.


    Transmission provides a better user experience compared to the complexity of competing services such as uBittorrent, Tixati and Vuze.

    What makes Transmission great from the user experience standpoint is that it can be configured to download files from folders, RSS feeds or any other source without having to control it manually. Downloading automatically from preferred sources as soon as the content is made available is a very helpful feature indeed.

    Transmission desktop clients can be remotely controlled, too, like most other torrent apps.

    Transmission’s interface is easy to use. In fact, it has the most barebones UI of all torrent clients, and strikes the right balance between functionality and simplicity. Its minimal UI, with no distracting adverts, is another highlight.

  • New Linux Software To Make Things Easier For AMD GPU Users

    Linux software has never really had a whole lot of attention from large companies such as AMD – but that might be about to change. One of the main draws of Linux is the vast amount of software created for free by the community.

    A recent piece of software has appeared which could make life a bit easier for AMD graphics card users.

  • LeoCAD 19.07.1 on openSUSE | Building to Publish

    I don’t generally have a lot of time to “play” with Legos, either real or virtual. When I do, it is mostly with my kids as a fun, family activity. Using LeoCAD is a great way to document the designs or work out ideas without having all the appropriate pieces and also makes for a great education tool to use with children or adults.

    I am able to take time, now and again, to explore my limited creativity and to share it with those that have similar interests on the Internet. Sure, my reach is probably only a dozen or so people scattered around the world that are approximately my age but that is just enough. The positive is, it ensures that when I go to to order the parts I want, they are not in high demand and I can get what I want pretty reasonably.

    I can’t thank enough those that are volunteering their time to create LeoCAD and all the tools that make my openSUSE Linux machine possible. Not to mention the various web services and sites that make sharing possible too. It’s a pretty great time in which we live, especially if you are a nerd.

  • 2.14.0 Released! :: Pidgin, the universal chat client

    Well it’s been a while, but we’ve finally released Pidgin 2.14.0. This is a special release for a number of reasons, which we’ll get into below. That said, you can find the source release on SourceForge as well as on Bintray.

    First of all we moved libgnt, the GLib NCurses Toolkit, to its own repository. It is the user interface library that was created for Finch. We did this for a number of reasons, most notably to let libgnt step out from Pidgin’s shadow and get the attention it deserves as a stand-alone project. That said, if you want to build Finch, you need to first install libgnt. You can find the source for it at SourceForge or Bintray.

    Secondly, this is most likely the last release that will be on Bitbucket. As many of you know, on July 1st Atlassian is deleting all Mercurial repositories. We are mostly done with migrating off of Bitbucket but there’s still some loose ends that need to be dealt with. Gary will be addressing this in an upcoming townhall-style meeting whose details will follow in the near future. In the meantime those loose ends need to be taken care of before that meeting. However, you can find the new home of the repository at

  • I'm booting my Raspberry Pi 4 from a USB SSD

    Recently, the Raspberry Pi Foundation announced a USB boot beta for the Raspberry Pi 4. For a very long time, the top complaint I've had with the Raspberry Pi is limited I/O speed (especially for the main boot volume). And on older Pis, with the maximum external disk speed limited especially by the USB 2.0 bus—which was shared with the network adapter, limiting its bandwidth further—even USB booting didn't make things amazing.

    But the Pi 4 not only separated the network adapter from the USB bus, it also has USB 3.0, which can be 10x faster than USB 2.0 (theoretically). So when the USB boot beta was announced, I wanted to put it through its paces. And after testing it a bit, I decided to use the Pi 4 as my full-time workstation for a day, to see whether it can cope and where it falls short. I'll be posting a video and blog post with more detail on that experience very soon.

12 Best Free Linux Time Tracking Software

Time tracking software is a type of computer software that records time spent on tasks. This category of software can enable users to run billing reports, and prepare invoices for clients.

The deployment of this software offers a new level of productivity to organizations, as it provides management with information on what time is spent by employees on different activities such as projects and tasks. This can help to measure productivity over time. This software is commonly used by professionals that charge clients by the hour such as accountants, solicitors, and freelancers. The generation of automatic invoices with minimal or no data entry removes the inconvenience of billing and invoicing clients, and improves efficiency.
