      @marcan42 @grsecurity One day you will all realize that a lot of this is due to C just giving you way too much rope to hang yourselves with

      @pmarreck @marcan42 @grsecurity please tell me when you are finished porting the Linux kernel to Rust, Golang or node.js ;)

      @marver @pmarreck @grsecurity Can't write kernels in Golang or node, but I'm considering Rust for my next bare metal kernel-like project.

      @marcan42 @pmarreck @grsecurity I know, it was a joke. :) just everyone blindly repeats everything will be better once we get rid of C..

      @marcan42 @pmarreck @grsecurity to see how great security is in a memory safe, strongly typed and even fully verifiable lang, look at Java.

      @marver @pmarreck @grsecurity IIRC Java isn't even concurrency-safe, while Rust is. :)

      @marcan42 @marver @pmarreck @grsecurity will rust automatically make sure you get locking in a kernel right?

      @marver @pmarreck Rust will at least make sure you can't segfault due to bad locking :-)

          @marcan42 @pmarreck yes that and other flaws in logic leading to privesc. To quote @cynicalsecurity: "There will always be a Belgium"

          @marver @pmarreck @cynicalsecurity Of course. It's no magic bullet, but it's still an interesting idea.
