Every time someone claims they've written a "bulletproof" app, I roll my eyes so hard I can practically see my brain. History's not on their side, and in this endless cat-and-mouse game between developers and hackers, it never will be. ๐Ÿ˜œ

This is for you, my friend. I know you follow me here, so consider this a friendly reminder from, well, nobody. ๐Ÿ˜‰

@nixCraft Not really. seL4 is an L4-based microkernel with mathematical proof it exactly meets its specification, with no missing behaviors and no undefined behaviors. For any reasonable definition of โ€œbugโ€, this is proof the software is bug-free. The specification can still have issues, but those arenโ€™t bugs in the software.

It takes a *lot* of discipline to write code to this level of assurance, but it *is* possible.
