At a higher level, one could use Gentoo to learn a lot about Linux internals with at least up-to-date packages and a "usable" distribution. One can experiment alot with Arch Linux too, if compiling is a burden.

If you are using a simple type (int, unit...), it could be optimized by the compiler. But if i is an iterator, you will create an unnecessary copy. Maybe a special treatment can be done for STL types. But in some other cases, expecting ++i&

Here take your rustwin point! I really like the explicit capture of C++'s lambdas more than the implicit one in most other languages (C#, Java, Python...) where you easily ends-up with a closure not referencing the expected variable. S

I already saw such a colleague training hard at competitive programming, everyday. Yet, he wrote that kind of C++ code: ressource AClass::CopyACriticalRessource() { { std::lock l; } // Optimization for

You just reached the Rustwin's point of Hackernews: "As a discussion about C++ or C grows longer, the probability of a comparison involving Rust, as a savior, approaches 1. Afterwards any further discussion is considered null and

I yet didn't check the proposal for C++17 concepts, it seems to constantly change since C++11. Does it includes anything related to variadic templates? Anyway, you must have had a lot of fun with Jaakko Järvi as a teacher!

Haskell and C++ look like the "elite" combo these days, especially when it comes to meta-programming and FP as you said! It's funny how these two different communities are mixing. It feels like JavaScript and Ruby having a ch

I see it as a language in itself. Once done with the steep learning curve you start to observe repeated patterns and get it more easily. I do agree that the syntax is a huge drawback from now.

Yes definitely tricky. It might give a heart attack to some high frequency system designers! I will investigate this topic in future: maybe someone can come up with a spin-lock or lock free solution.

Thank your Sir! Sadly C++ drags a bad reputation from its earlier years. I wish my posts make C++ reachable and enjoyable for common guys like me.

As I explained in a commentary: As far as I understand gcc implementation. In a pseudo-code it would be: Mutex mutexes[SIZE_OF_POOL]; int hash(void* p) { ... } std::shared_ptr<t> atomic_load( const std::shared_ptr<t>* p ) {

I have no clue on how to generate a patch. But I did a fair amount of pull requests... It might be a generation problem.

I have to agree on this. I was surprised to see that a majority of the Rust community actually comes from some web-development domains. Especially when comparing Ruby, a highly flexible dynamic language, to Rust a language full of constrain

I am genuinely interested in this. Do you have any good reference about it?

It's not really a bug, but a feature standardised in C++11 to avoid unwanted failures with a trailing template somewhere in your code. But this feature was hijacked to do type checks! Maybe a better example would be a project that mix

Exactly! No matter the future of Rust, it has already shaken the programming community and motivated the other language designers to catch up in that domain. As to guess whether Rust will put down C++ forever and ever, is another hard quest

One can simply ditch the C++ backward compatible features into an "unsafe" part of C++. That's exactly what the talk given by Herb at the CppConf is trying to address. All the old unsafe part of C++ will trigger errors or war

The GDP per capita tab is really interesting if you want to estimate the life standard of each province. GDP itself is interesting for the "global power"/influence of each province over another one.

You can click on the tab: GDP per capita. And there you will see that Guangdong is as rich as kazakhstan.
