    Project mention: Password-stealing Linux malware served for 3 years and no one noticed | news.ycombinator.com | 2023-09-12

    This is installed by adding a shady repository to your apt sources.list...

    How is this a supply chain attack? My official debian repository have never been breached so far.

    This is no different from downloading an .exe of a shady website and running it.

    Also: https://packages.debian.org/search?keywords=download+manager... lists:

    • uget: https://sourceforge.net/projects/urlget/

    • kget: https://apps.kde.org/en-gb/kget/

    • persepolis: https://persepolisdm.github.io/

    why use "Free Download Manager"? Is this targeting new-comers from windows?

    I used DaVinci Resolve but it was very sluggish on older hardware.

  • notes

    Fast and beautiful note-taking app written in C++. Write down your thoughts.

    Project mention: Why I Like Obsidian | news.ycombinator.com | 2024-01-17

    Plume is built on top of my open source note-taking app Notes[1]. Since Plume is based on Notes, I'll of course comply with the MPL license and release all existing files that were changed (and must stay MPL licensed).

    But I recently discussed my reasoning to go close-source with Plume[2]. I've been working night and day (every day) converting 4 cups of coffee into code for the last 4.5 months to create Plume. I don't want to risk not being rewarded sufficiently for it. But, I'm 99% sure that I'll either open source the core block editor or the entire app in the future.

  • Librum

    The Librum client application

    Project mention: Librum: Open-Source e-book platform | news.ycombinator.com | 2023-12-18

    >Why should they have to justify providing free software?

    They don't, but they have to be honest about what they're presenting. There's this shitty motte-and-bailey situation in open source where their website ( https://librumreader.com/ ) looks like marketing for a serious application - but the moment you treat it like a serious application, people are like "it's free, why are you treating it like a serious application?".



    >Focus on what actually matters, using a simple and straight forward interface.

    >Your time is too valuable to be wasted on complex applications.

    What does the tone here convey? Is it "this is just a cool project I wrote"?

  • opentrack

    Head tracking software for MS Windows, Linux, and Apple OSX

    Project mention: TrackIR VS Cheaper alternatives | /r/dcsworld | 2023-10-04

    I want to buy something like TrackIR (I don't know much about equivalent products). My friend told me about a DIY tracker that I could use (opentrack).

  • apkstudio

  • nodeeditor

    Qt Node Editor. Dataflow programming framework

    Project mention: What would be required between my car's wiring harness and a mini-pc/raspi to handle media and map steering wheel buttons? | /r/CarAV | 2023-03-14

    Options are limited. Look here: https://github.com/f1xpl/openauto

  • Qt

    Qt Base (Core, Gui, Widgets, Network, ...)

    Project mention: Current Issues With The Qt Project - From The Outside Looking In | /r/QtFramework | 2023-04-20

    Qt mono repo : .. you could check out all submodules and simply use CMake to exactly achieve this. A mono repo also means that if I only use qtbase and declarative, I would need to have all submodules in there? - No

  • examples

    Learn to create a desktop app with Python and Qt (by pyqt)

  • git-cola

    git-cola: The highly caffeinated Git GUI

    Project mention: Ask HN: Can we do better than Git for version control? | news.ycombinator.com | 2023-12-10

    > Visual Studio does a decent job of abstracting the GIT nuances, but I personally use GIT Extensions, which looks and feels much better on Windows than the other cross platform UIs.

    IDEs and text editors sometimes have nice Git integrations in the UI, but I wanted standalone software that I can use for anything from various programming projects, to something like gamedev projects (with Git LFS) or arbitrary documents.

    In the end, I just forked over some money for GitKraken, it's pretty good, especially with multiple accounts on the same platforms, when you want to switch between them easily: https://www.gitkraken.com/

    There's also Sourcetree which I used before then, kind of sluggish but feature complete: https://www.sourcetreeapp.com/

    For something more lightweight, I also enjoyed Git Cola on various OSes: https://git-cola.github.io/ Even Git documentation has a page on the software out there, a good deal of which is free and has good platform support: https://git-scm.com/downloads/guis

    Quite frankly, I spend like 90% of the time using a GUI interface nowadays, when I want to easily merge things, or include very specific code blocks across multiple files in a commit, or handle most of the other common operations. Of course, sometimes there's a need to drop down to the CLI, but you're right that some GUI software feels like it actually improves the usability here.

  • linuxdeployqt

    Makes Linux applications self-contained by copying in the libraries and plugins that the application uses, and optionally generates an AppImage. Can be used for Qt and other applications

    Project mention: Two reasons because Arch-based AppImages are not a good idea | /r/archlinux | 2023-05-05

    The second reason is the "modularity" of Arch, why Debian packages all the dependences in many different packages? Because a developer can isolate a bug or exclude that package using the right patch. Arch tends to package everything together. That's why an AppImage of Chromium for me is about 140 MB from a Ubuntu base and 280-300 from an Arch-base... but at least this is an issue of both arch-deployer and arch2appimage... I think that by using linuxdeployqt would be better in this case (SPOILER, it requires the host system with an old GLIBC version, also Debian Bookwork is too new for it xD ).

  • awesome-qt-qml

    Project mention: "How i learned about Firefox MPRIS" - or - "[PSA/FYI] Add years to your life by avoiding this critical 'WTF?!?' moment." | /r/firefox | 2023-03-13

    about this time, i am a little more than intrigued and a bit confused. i use my image viewing program qimgv (github) by typing qimvg 87956_60.png and was shown a photograph of a man seemingly turning his head to look at me.
