Social recommendations and mentions

  • ScummVM officially released in the App Store
    > ...even though they are technically in violation of the GPL by modifying and shipping bash binaries without full source - it is missing rootless.h (not the X11 file) They're not. They've covered this in two main ways: 1) By listing all their source code on https://opensource.apple.com/ (which links to their GitHub with all the source code) 2) By offering a complete machine-readable copy of the source code upon... - Source: Hacker News / 4 months ago
  • macOS 13.5 source code released
    The XNU kernel has been open source for a very long time. https://opensource.apple.com https://en.wikipedia.org/wiki/XNU Note that this is not the full operating system/windowing system, it's just the kernel. - Source: Hacker News / 9 months ago
  • Apple’s new Proton-like tool can run Windows games on a Mac
    Apple does plenty of open source stuff. Safari's browser engine, Swift, libdispatch, the XNU kernel used by iOS and macOS, etc. And macOS is generally packed with open source things, like the default shell, zsh. Also, Metal actually predates Vulkan, so Vulkan was definitely not established when they started focusing on Metal. Yeah, they probably should consider supporting Vulkan now, but it's nothing to do with... Source: 11 months ago
  • DirectX 12 Support on macOS
    It's still not a great thing to do. Apple used to contribute a lot more, even if some of their stuff was exclusive to their platform. https://opensource.apple.com. - Source: Hacker News / 11 months ago
  • [D] ClosedAI license, open-source license which restricts only OpenAI, Microsoft, Google, and Meta from commercial use
    Everything that includes copyleft code is open source. You can see https://opensource.apple.com for a full list. Source: 12 months ago
  • Why windows has more known bugs?
    Apple and MS have code-sharing programs (https://opensource.apple.com/ , https://www.microsoft.com/en-us/sharedsource/) where corps and govts and researchers can see the source code. It's just not open to the general public. [And apparently Windows source code has been leaked multiple times: https://fossbytes.com/windows-10-source-code-leaked-online-report/... Source: about 1 year ago
  • Google to start using Blink engine for Chrome iOS will Firefox use their own?
    I dug around ab it and their open source project list is remarkably short: https://opensource.apple.com/ with one of them being a direct competitor to Blink (webkit). Source: about 1 year ago
  • An M1 for Curl
    Apple contribute a lot to open source, and I think your last statement of them being a negative force is kind of ridiculous given some of the work that heavily depended on their engineering. Firstly, they have a site that lists some of their work https://opensource.apple.com/ but going further, projects like Chrome wouldn’t exist without Safari having forked KHTML and then massively worked on WebKit. Clang + LLVM... - Source: Hacker News / over 1 year ago
  • ForeFlight Discontinues Lowest Tilt Radar Display
    Developer and mediocre pilot here. This isn't correct. Being open or closed source does not inherently make something more or less secure. Additionally, while Android (the operating system and kernel) is open source, the apps you run on it do not have to be open source. Google actually has a bunch of software running on android, such as their own apps and services, that are not open source. In a similar twist,... Source: over 1 year ago
  • Is it possible current encryption algorithms have backdoors?
    The devs would know. And many supposed closed-source companies have source-sharing programs, such as https://opensource.apple.com/ and https://www.microsoft.com/en-us/sharedsource/ , where corps and govts and researchers can see the source code. It's just not open to the general public. Source: over 1 year ago
  • The real reason to tweak your kernel is for the jokes.
    There's also https://opensource.apple.com/, which previously hosted all of their codes now on github. PLUS, all of these 25 commits are uploaded by release, and most of them are large. They don't commit whenever they add a change, they commit per release. Source: over 1 year ago
  • YSK: MacOS saves a copy of everything you print forever. Here's how to view the files.
    Should they take LLVM, WebKit, Swift, and, aptly, CUPS back then? Not to mention the 182 open source repositories on GitHub or all the others on their open source website. Quit letting your biases cloud yourself from reality. Source: over 1 year ago
  • Why do many Linux fans have a greater distaste for Microsoft over Apple?
    And Apple has also great contributions to Open Source. While their OSes aren’t completely open source, the most central parts of them are (it’s based on freeBSD after all), including the kernel. Check their website. Ever used a printer on your Linux system? You’re using Apple open source software. Source: over 1 year ago
  • A New Life for Certificate Revocation Lists – Let's Encrypt
    That is a very good question and I don't know the answer, but if you want to go source code spelunking, you can probably find the answer on https://opensource.apple.com/. - Source: Hacker News / over 1 year ago
  • Apple's WebKit comes to GitHub
    Here are some of the feature Open Code projects (OpenSource.Apple.Com). Source: over 1 year ago
  • Apple's WebKit comes to GitHub
    Look at their open source site now (img)and look at this snapshot (img) from barely a year ago. Source: over 1 year ago
  • My contribution to the browser discourse (arch btw)
    Apple has a dedicated Open Source website: https://opensource.apple.com. Source: over 1 year ago
  • MacOS sourcecode
    Thank you for your answer, I've seen the custom darwin code, but as I mentioned on the original post, at macworld 2000 steve quoted that macOS 10.0 is going to be open source, but as of what I can find, the open source parts in the source code from opensource.apple.com are just 16KB. Source: almost 2 years ago
  • MacOS sourcecode
    Hello everyone. I am new in reddit, as you can see. I had known for a long time, that the macos 10.0 code was open source, (macworld 2000) but I stil can't find it to this day, since at opensource.apple.com the source only includes only minor parts of the OS (not including anything you would want), it was mostly empty. Any idea why? If anyone knows where to get the real source, please tell me. Source: almost 2 years ago
  • Chinese government to dump Windows in favor of Linux -
    Apple and MS have code-sharing programs (https://opensource.apple.com/ , https://www.microsoft.com/en-us/sharedsource/) where corps and govts and researchers can see the source code. It's just not open to the general public. Source: almost 2 years ago
  • Windows privacy
    MS and Apple both have source-sharing programs, open to corps and govts and researchers who sign up: https://www.microsoft.com/en-us/sharedsource/ and https://opensource.apple.com/ They're just not making source available to the general public. Source: about 2 years ago
