co_lib - experimental asynchronous C++20 framework that feels like std library Inspired the way how boost::fibers and Rust's async-std mimic standard library but in asynchronous way, I try to write c++20 coroutines framework that reuse std library concurrency abstractions but with co_await. It's mostly experimental and on early stage. But I would like to share with you some results. The library itself: https://github.com/dmitryikh/co\_lib (proceed with examples/introduction.cpp to get familiar with it). Here is an attempt to build redis async client based on `co_lib`: https://github.com/dmitryikh/co\_redis My ultimate goal is to build `co_http` and then `co_grpc` implementations from scratch and try to push it to production. https://redd.it/lhv0ur @r_cpp

Do I have to be good at math to be a reverse engineer? I'm learning the basics of C++ and I was wondering if I have to be a math genius to be a Reverse engineer I'm not really good at math but I find learning C++ fun https://redd.it/lhn2c0 @r_cpp

IPFIX Flow Exporter Written in C++ Hello everyone, I thought about sharing my Master's Thesis program with everyone. It is an IPFIX Flow Exporter written in C++ designed to properly process packets in network that use multiple VLANs/VXLANs or GRE. It is capable of exporting IPFIX records in such a way that they properly describe the original packet structure. ​ I was hoping that someone might have time to check it out, or maybe even use it. Any feedback is welcome. ​ Here it is: https://github.com/CSIRT-MU/flower https://redd.it/lhneyy @r_cpp

Fastest way to transpose a binary matrix? Imagine you are given an array of 32 32-bit ints representing the rows of a (32x32) binary matrix. What's the fastest way to transpose it (i.e. obtain a similar array which now represents the columns of the original matrix)? Can we do better than ~1024 steps? https://redd.it/lhmrqm @r_cpp

I've been developing in C++ on and off for ~5 years, but I can barely read the answer to this question, much less write it myself... is this normal? Question 7(I think) on this page: https://www.toptal.com/c-plus-plus/interview-questions >Implement a template function IsDerivedFrom() that takes class C and class P as template parameters. It should return true when class C is derived from class P and false otherwise. Answer: >>!This question tests understanding of C++ templates. An experienced developer will know that this is already a part of the C++11 std library (std::is_base_of) or part of the boost library for C++ (boost::is_base_of). Even an interviewee with only passing knowledge should write something similar to this, mostly likely involving a helper class:!< >!template<typename D, typename B>!< >!class IsDerivedFromHelper!< >!{!< >!class No { };!< >!class Yes { No no[3\]; };!< >! !< >!static Yes Test( B* );!< >!static No Test( ... );!< >!public:!< >!enum { Is = sizeof(Test(static_cast<D*>(0))) == sizeof(Yes) };!< >!};!< >!template <class C, class P> !< >!bool IsDerivedFrom() {!< >!return IsDerivedFromHelper<C, P>::Is;!< >!}!< &#x200B; The part that says "Even an interviewee with only passing knowledge should write something similar to this" is especially jarring. I can barely read the code above, much less actively write it in a tense interview. I've written most of my code alone, and I very rarely use template types(and I'm almost certain any template types I use would be afterthoughts, not written during "active" writing). In the interest of bettering myself and becoming a better developer, this raises a lot of questions for me about how I've gotten where I am without knowing this: Do I just need to read more open source code? Did I not work on enough group projects in college or something? Is the main method for learning advanced techniques like this not learned on the job? Do I just need to force some templates into a few of my projects? https://redd.it/lhjfox @r_cpp

Do we have a convenient build tool for C++? I really don't understand CMake. I'm spending more time trying to make that thing work than writing code. I used Make. Not the friendliest thing and I don't want to return to it. I used QMake. Don't remember serious problems with it, but now I'm going away from Qt (and as I heard Qt is also deprecating QMake) so... What do I want? I want an automatic build tool: I give it the names of the source files and needed libraries and get the binary. I want this tool to automatically resolve dependencies. I want it to be useful and simple. As I understand the main problem of all those build systems is that they are language-agnostic. They are not able to resolve dependencies. Why would I want them? I can write a trivial and simple to maintain bash-script that will do the building. But still, maybe we have a C++ convenient build system? Does anyone know one? https://redd.it/lhfpy3 @r_cpp

When do you think modules will be fully implemented? As you probably know, none of the compilers have a fully working module implementation yet (I'm using Visual Studio and even though it's officially supported it is basically unusable because of various bugs). So my questions to the experts is simple - when do you guys think we can expect to have this feature fully working? https://redd.it/lhf741 @r_cpp

I'm looking for a good data structure & algorithm text to study C++ Any recommendation? I'm having a hard time learning stacks, queues, Link-list, hash table, implementing those and etc. Especially, I don't know how to code those, and I need to learn in order to pass the class that prof's explanation is nearly impossible to learn thank you https://redd.it/lh9eps @r_cpp
