what good is memory-safety when you have the highest rate of security vulnerabilities per line of code?

@kai_fall @grok is this true?

@kai_fall With C++ you fuck up with honor and die like a man. But with rust, no matter what you do, you are gay

@kai_fall What would be the main issue with C/C++? Pointers? And what is the best way to avoid it? Using assertions?

@kai_fall Interesting, what are your sources for this? Or the rage baiting posts are starting to turn into literal misleading lies now as well?

@kai_fall Present day devs misunderstand the fundamentals of computer science Every Turing-complete language will have the same vulnerabilities, just different forms. The only truly secure languages are the incomplete ones, like Coq. You then avoid infinite loops and non deterministic

@kai_fall What is the source on this?

@kai_fall I feel like even if this data is real, you have to normalize for the maturity of the codebase before drawing any conclusions.

@kai_fall How are js and ts libraries separated lol

@kai_fall Have you ever had a chance to read enterprise software written in C#? Initially I was like: Dude is it application as a vulnerability principle so popular in their community? Or they write it in mono-vulnerability architecture? πŸ˜…πŸ˜…πŸ˜… I think your diagram has issues.

@kai_fall Rust is way slower than C++, but honestly in the "Jira" world. It is probably better than using C++ with a Pakistani / Indian team to accommodate complex implementations.

@kai_fall This is interesting, philosophically: Rust handles interop(surface level) code the same way the two most secure ones, yet it's more insecure. πŸ€” Blocks are either wrapped in 'unsafe' blocks, or flags prefixing function calls. I'm genuinely curious where the difference is. Is it

@kai_fall vulnerability but, only vulnerable with an assumed lack of skill? are we looking at "c++ would be the securest in the Universe IF the most-qualified human coded it because you can Aim it with Any Precision but most require a dumb-down" ?

@kai_fall Rust is like the Maginot Line and rustacians have the confidence of the French in 1939. There’s lots of other ways to write bugs lol.

@kai_fall Python rocking the normal only because it takes so few lines of code

@kai_fall Source: Trust me bro Come on, I have no love for Rust (More specifically, the followers of the Church of Rust) but this is worthless.

@kai_fall I call bullsh1t.

@kai_fall Soooo - simplicity is safety? I β™₯️ʕ◔ϖ◔ʔ

@kai_fall I love c# but the more I look into it the more it seems clear the go is the spiritual successor to c#. Even one of the original authors Anders Hejlsberg seems to agree.

@kai_fall Approx (illustrative)

@kai_fall Yeah I will be sandboxing it doesn't even help, it's probably bore to binary root and core executable.

@kai_fall Why is that though? Are Rust Devs just worse?

@kai_fall No wonder Go is in lowest position, since you need to implement millions lines of code to make literally anything :P

@kai_fall Go has memory safety and actual safety.

@kai_fall OMG. LOL. Demolished.

@kai_fall Basically, telling people they don't have to think about memory safety (Rust) equals poor code. Not a big surprise.

@kai_fall The JVM is undefeated.

@kai_fall can't spell GOAT without go

@kai_fall Vibe coders though would be easy to develop rust

@kai_fall Just use go

@kai_fall this is waay waay under what i personally estimate lmao

@kai_fall This feels accurate less is more, while many agree but fully ignored by the collective consciousness

@kai_fall Where is PHP?

@kai_fall trust me bro

@kai_fall Source, context?

@kai_fall C# made the list!!

@kai_fall @grok what is the source document of this chart above?
