C++ syntax is notoriously complex and full of gotchas both for compilers and for humans. I don’t know what was the reasoning in selecting the syntax for template deduction guides […]
C++
Fun with fold expressions

This is a continuation of the series about C++ rvalue references. First post, second post, third post. Rvalue references are unique, because if you have a variable of type T&&, […]
Forth to the past: C++ “features” that make life hard

Forth to the past: C++ specification costs top dollar (and why this is bad)
This is a continuation of my previous post about rvalue references. As you may know, official C++ specification is not free: it costs upwards of $100, which, I dare to […]
Forth to the past: C++ rvalue references (T&&)
This week-end I looked at C++ rvalue references and move semantics. Here’s the code, the good stuff is in matrix.h. Rvalue references seem useful, but way too treacherous. Any programming construct that raises […]

I wrote a tool called “IsItMySource” that can list source files of a binary and, more importantly, check whether particular source directory matches the binary. The description is here: https://www.ikriv.com/dev/dotnet/IsItMySource/index.php. The […]
