Surface 3 Review
I received Surface 3 with keyboard/pen bundle on May 5th, probably the last UPS drop of the day after 7 pm, needless to say it was a long day of anticipation. I have been busy installing and playing with the device since then. After about two months, so far I'm very pleased with it.
Is it …

The memory leaks are detected using a custom memory allocator (using an atomic counter for allocation/deallocation size). In single thread mode, the program terminated without leaking, but running in multithread mode …

LLVM, Clang, and (no) Auto Vectorization
