  • [Handmade Network] How to write better (game) libraries
    Even if someone wants to use VS2008 for game development, it only took me a Google search to find which doesn't have any dependencies and a very permissive licence.
  • how do i include glfw in my code to make a window? | 2021-08-31
  • LibOS – Cross-platform OS features in C++ | 2021-08-23
    You seem to have had a similar impetus as I had 20 years ago when I created GLFW (though with a slightly different focus).
  • Is there a way to get japanese text input in raylib? | 2021-08-23
    Thanks for the detailed explanation. I'm afraid I didn't considered that use case for raylib and it would require some investigation to implement it... but raylib uses internally GLFW for desktop platforms and I've seen there is a related issue: About IME support by the browser, it should be investigated. Feel free to open an issue on raylib GitHub for further investigation!
  • Massive trouble with GLFW header inclusion. Can someone help?
    Looking at the actual code of the .h file, it looks pretty empty, and like it needs some extra files perhaps. For instance, functions are just filled with comments with some random explanations, so they are basically 1 line, which probably does nothing. Here you can take a look yourself on github.
  • Hey, I want start
    I would suggest using GLFW and Glad with C++ and use LearnOpenGL as a refrence
  • Compiling in MacOS M1 Chip (arm64) | 2021-07-22
    Now I read the logs and it seems the issue is with GLFW. I've found this:
  • Opengl(glfw) gears on termux x11 NO ROOT!! | 2021-07-19
    Clone the glfw repositiory - git clone
  • 3D Visualization with C++
    Use to get a window with an OpenGL context.
  • A better way of running Minecraft Without XWayland. Because I REALLY had nothing better to do with my life. (which is where I got some patches from) says there wasn't much upstream interest on merging the patches. But (the fix for the freezing issue) might be a good candidate for merging, though I don't know how GLFW people work, so I cannot comment on if it is properly upstreamable or not.

  • What we learn from twitch source code leak | 2021-10-11
    I mean, it hasn't grown to a thousand entries, but
  • TIL: There's a guy who is responsible for maintaining the database of time zones which computers and operating systems use to configure locales. His name is Paul Eggert. And he's a computer scientist based in California.
    It wasn't made by a single guy. OpenSSL was forked from SSLeay that was made by 2 guys (Eric Andrew Young and Tim Hudson) and they maintained it for a few years. There seem to be 3 developers (Richard Levitte, Stephen Henson, Andy Polyakov) who have contributed for 23 years straight according to the contribution graphs.
  • The difference between Go and Rust
    And yet they all do
  • OpenSSL 3.0 | 2021-09-07
    There are a lot of little tidbits in the changelog. For example:

    “Interactive mode from the openssl program has been removed

    From now on, running it without arguments is equivalent to openssl help.”

  • OpenSSL security advisory (2021-08-24) | 2021-08-24
    It looks like its inclusion is guarded by a compiler flag:

    If anyone needs to know if SM2 is enabled quickly on any system, this is guaranteed to include SM2 if it's compiled:

        openssl list --public-key-methods | grep sm2
  • Need help where to download OpenSSL for Windows 7 and if it's safe to use OpenSLL? | 2021-08-12
    Nornally, you need to compile OpenSSL yourself, since they only offer the source code. But you can look here to see which websites offer 3rd party binaries for it. But I can't tell which one is safe.
  • Bug in Lynx' SSL certificate validation – leaks password in clear text via SNI | 2021-08-07
    Let me say, I really appreciate OpenSSL, and it's made amazing progress in terms of security over the last few years. I make monthly donations to the developers as I believe it's critical infrastructure. Buutt...

    From [0], the issue arises when they send "user:[email protected]" to SSL_set_tlsext_host_name, which happily sets the SNI to whatever it's given [1]. As a point of comparison, when you create a Rustls client via ClientSession::new [2], you have to pass it a DNSNameRef, which will validate that there's no auth component in the string it wraps, and return an error if you try to set the server name to something involving auth details.

    I'm sure there's reasons why OpenSSL is set up to work like this, but I can't see why anyone would ever want to send those auth details in the clear in the SNI, and I wish it provided an API that would anticipate this misuse, like in Rust. The OpenSSL docs don't indicate it's an issue you should think about when invoking this function [3].

    I realise I'm picking on OpenSSL here, and GnuTLS appears to do the exact same thing. I'm just not certain anyone not wearing a hazmat suit and being watched by multiple other trained professionals should be handling OpenSSL code.
