Around 70% of our high severity security bugs are memory unsafety problems (that is, mistakes with C/C++ pointers). Half of those are use-after-free bugs.(Analysis based on 912 high or critical severity security bugs since 2015, affecting the Stable channel.)These bugs are spread evenly across our codebase, and a high proportion of our non-security stability bugs…

Image: Google Roughly 70% of all serious security bugs in the Chrome codebase are memory management and safety bugs, Google engineers said this week.Half of the 70% are use-after-free vulnerabilities, a type of security issue that arises from incorrect management of memory pointers (addresses), leaving doors open for attackers to attack Chrome's inner components.The percentage…

Neut is a dependently-typed programming language based on the Calculus of Constructions (CoC). The interesting point is that this language determines how to allocate/deallocate memory at compile-time, without extra annotations to the type system. In other words, Neut in its source language is the ordinary lambda-calculus after all (imagine something like Haskell, OCaml, Idris, Coq,…

If your Python data pipeline is using too much memory, it can be very difficult to figure where exactly all that memory is going. And when you do make changes, it can be difficult to figure out if your changes helped. Yes, there are existing memory profilers for Python that help you measure memory usage,…
