| | | | | In the Linux world, the eBPF technology has been around for years. Its purpose is to allow writing programs that run within the Linux kernel. However, contrary to standard kernel modules, eBPF runs in a constrained environment, its API is limited as to not hurt the kernel. Furthermore, every eBPF program must be verified before... | |

| | | | | Raw pointers in C/C++ open up entire classes of error that are practically unimaginable in higher level languages. So why does anybody use them at all? Unfortunately, it's impossible to write a profiler without getting close to some of the sharp edges of unsafe memory. The async-profiler code base contains a lot of low level tricks, and it's worth studying how some of them work. | |

| | | By now, everyone knows that something "big" just got announced regarding computer security. Heck, when the Daily Mail does a report on it , you know something is bad... Anyway, I'm not going to go into the details about the problems being reported, other than to point you at the wonderfully written Project Zero paper on the issues involved here. They should just give out the 2018 Pwnie award right now, it's that amazingly good. | ||
