Protect .NET code from reverse engineering?
Obfuscation is one way, but it can't protect from breaking the piracy protection security of the application. How do I make sure that the application is not tampered with, and how do I make sure that the registration mechanism can't be reverse engineered?

Replacing a 32-bit loop counter with 64-bit introduces crazy performance deviations with _mm_popcnt_
...(and the compiler isn't even aware of it)
On Sandy/Ivy Bridge and Haswell processors, the instruction:
popcnt src, dest
appears to have a false dependency on the destination register dest. Even though the instruction only writes to it, the instruction will wait until dest is ready before execut...

How would Git handle a SHA-1 collision on a blob?
This probably never happened in the real-world yet, and may never happen, but let's consider this: say you have a git repository, make a commit, and get very very unlucky: one of the blobs ends up having the same SHA-1 as another that is already in your repository. Question is, how would Git handle ...

C++ performance vs. Java/C#
My understanding is that C/C++ produces native code to run on a particular machine architecture. Conversely, languages like Java and C# run on top of a virtual machine which abstracts away the native architecture. Logically it would seem impossible for Java or C# to match the speed of C++ because ...
How do I use arrays in C++?
C++ inherited arrays from C where they are used virtually everywhere. C++ provides abstractions that are easier to use and less error-prone ( std::vector<T> since C++98 and std::array<T, n> since C++11 ), so the need for arrays does not arise quite as often as it does in C. However, ...
Why is it slower to iterate over a small string than a small list?
...T 0 (None)
#>>> 20 RETURN_VALUE
This produces just
9 LOAD_CONST 6 (('a', 'b', 'c'))
as tuples are immutable. Test:
>>> python3 -m timeit '[x for x in ("a", "b", "c")]'
