 We built a new playground called Memory Spy where you can spy on a program's memory! It's at https://memory-spy.wizardzines.com. I made this with @omarieclaire, and there's a blog post about how and why we built it here https://jvns.ca/blog/2023/05/25/new-playground--memory-spy/. Here's a gif: 10 comments
@b0rk the example "3 integer sizes" has 4 different kinds of integers, unless i missed something! this whole website is an extremely thin wrapper around lldb, you can think of it as an advertisement for how cool gdb/lldb are :)  @b0rk how do you manage to sandbox it? Iβve always wondered about sandboxing something like this @bnut i used bubblewrap (which i wrote about here) https://jvns.ca/blog/2022/06/28/some-notes-on-bubblewrap/ but you could also just use docker @bnut the real secret though is to present an extremely low-value attack target so it's not worth people's effort to try to break into @b0rk nice! Iβll take a look at your bubblewrap post, thanks! I guess in addition to malicious code thereβs also poorly written code taking down the server, haha. @bnut there's a 1 second timeout too, I talk about in the project's blog post / about page @b0rk nice, and itβs good to see that the bubblewrap post deals with launch times, that was my main question about using Docker |
