I am just expressing my opinion. You know, taking distraction from mundane work to talk technical things. I am not trying nor do I need to prove how I do my development/design and what tools do I use and frankly I do not give a flying hoot what others might think about it. I run my own business after all.
As to you particular point of language being unsafe because it allows typecast pointer to integer: allowing unsafe features in my view does not make language unsafe as long as it provides safe way of doing things as well. It is called flexibility in my book.
Security wise: could I've done better? Sure. Anything could be done better but you've probably heard about the law of diminishing returns. Does the fact that I use language that have unsafe feature automatically make my software unsafe if I do not use said features - big fat NO. Even if do use such feature (and rarely but sometimes I do for the sake of efficiency) it does not really change the main point.
As senior engineer at a security conscious firm, who used to freelance by writing exploits for code written by developers with your attitude, I want to make sure we don't use your software.
