Thread Rules
1. This is not a "do my homework for me" thread. If you have specific questions, ask, but don't post an assignment or homework problem and expect an exact solution.
2. No recruiting for your cockamamie projects (you won't replace facebook with 3 dudes you found on the internet and $20)
3. If you can't articulate why a language is bad, don't start slinging shit about it. Just remember that nothing is worse than making CSS IE6 compatible.
4. Use [code] tags to format code blocks.

That does not stop clients from demanding you (or in this case Manit0u) to make it work.

I've told the project manager to contact the client and make him reconsider. Either he uploads only webm and mp4 or he uses youtube and vimeo.

They also wanted thumbnails for it all, and if you click on a thumbnail it should open the video in the popup with all the controls and all...

Screw that, really. Creating thumbnails and converting all the videos to proper formats with ffmpeg right after they're uploaded seems like such a nasty solution. I mean, it would be fine for small movies but if they start uploading some 700+MB videos that could take some time and hamper server's performance.

It's not that difficult though

Just mention he needs something like Adobe Media Server for conversion and steaming, and use HTML5 video for playback.

Oh, too expensive? Well it can't work otherwise.

nunez, what compiler are you using?

vs14 barfs on that code TT

hahaha, yes it does! since i'm just writing for fun i'm not taking care to use features that are supported by all compilers.
fresh gcc with -std=c++1y flag is what i'm using.

it's probably protesting both constexpr and decltype(auto)!
after visual studio update 2 broke some (correctly written) template machinery code i wouldn't trust it with alias templates and default arguments on function template parameters either, allthough it's probably working fine now.

template barfs are hillariously painful to parse, the compiler is giving a sarcastic, reversed play-by-play of how it punched itself in the face on your command.

Oh so your the author of that sequence library too?

yeah, you posted some code on how to use it but deleted the seq::forward header. heh

And the compiler mostly barfs on select_if
Looks like SFINAE is not working.
So substitution failure is a failure

As far as i know decltype(auto) works in all cases now. And constexpr works everywhere except member functions.

ah ye. i only put it up on bitbucket to sync twixt my computers, calling it a library is very kind of you.
it's a collection of misnomers and half-baked ideas relating to operations on sequences of types,
but it is very handy when i am tinkering.

in my latest posts i cut out some of the things (includes in particular) to shorten code, dunno if i posted the entire source at the end, i should have in any case.

select_if is just ~another name for enable_if_t. a bad idea really, but without the _t defect (the metafunction call should not suffer the naming convention, the metafunction implementation should) and with a more accurate name for the cases i was using it for at some point (when the enabled whatever is in fact, by design, selected).

select_if implementation is: here

oh really? that's great news if it's the case, my info must be dated.
means i can pretty up some code at work.
when you say member functions, do you mean static memberfunctions too?

actually looks like it's not.
http://msdn.microsoft.com/en-us/library/vstudio/hh567368.aspx

Here it says No in all versions and cases

Which is wierd because it does work for regular functions


constexpr int times(int f)
{
	return f * 2;
}

...

std::array<int, times(5)> myarray;

Not sure where i heard that info now.

At my job, i don't have to worry about any of this because my work compilers are vs10 and below.
But, playing around with new stuff is fun at home. The FSM looked interesting.

the new stuff is juicy.

i just remembered that variant uses another metafunction (mimic) i haven't put on bitbucket and also it uses ref qualified functions, which i think is not supported either.

the fsm framework is sweet because it's very minimal, nice for prototyping.
would be interesting to do a performance comparison with boost's fsm as well.
i'll try remember to do that next, can do it in vs14 compatible way, with all the headers in place.
much more fun for me if you are able to tinker with it too.

Cool that'd be nice.

edit:

ref qualifed functions appear to work


struct S {
	void f() & { std::cout << "lvalue\n"; }
	void f() && { std::cout << "rvalue\n"; }
};

...
	S s;
	s.f();            // prints "lvalue"
	std::move(s).f(); // prints "rvalue"
	S().f();          // prints "rvalue"

All as expected.

And these constexpr uses also work


// Works
struct Test1
{
	static constexpr int value{ 15 }; 
};

// Works
template<class... Tn>
struct Test2
{
	static constexpr int value{ sizeof...(Tn) };
};

New intern. 50+. I ask about git. He says something along the lines of "Yeah, I've downloaded some zip files from GitHub before."

Kill... meeeee...

I hope that what you mean by 50+ is not the age of the intern. Please not. By the way, as a junior, I've never used Git, ever (I have one project in my one repository, which I only used sync and commit, not even update. Because I was the sole contributor to that project).

It is. And he won't stop asking questions that you can google instantly, not even related to work...

And as an intern in my previous company I had to do merge requests into development from the get go and was responsible for some merge requests into production 1 month in. It sure taught me to look VERY carefully at the code. Both mine and other people's.

It took me about 3-6 month of using git and being forced to work with feature branches before I really got git after working for decades with cvs and svn. It's definitely worth spending the time to dig into git.

Yeah, life without git is unimaginable.

btw. everyone should update their git if they're on Windows or OS X, there were some pretty nasty bugs found in releases for those platforms last week.

So I'm here for a little advice. =) I'm a Junior webdeveloper. I'm mainly working as a back-end developer with PHP, Laravel. As of interest I want to get into game development as a hobby. I don't expect to create anything awesome anytime soon, but i just want to learn. Obviously I've googled a lot and a lot of different opinions.

I thought about learning C++ and C#, but then i read that XNA will not be supported on a lot of platforms anymore. Which makes me anxious about getting into it.

I could still learn C#, and go with Unity. For Unity i could even use javascript, which i obviously don't have to learn from scratch, but i feel learning C# will make me a better programmer.

I guess this question has been asked at least hundreds of times, but out of experience i know TL is mostly filled with Wise people who can show me some good insight and point me into the right direction!

Anyone has experience with the languages Rust and Go? Especially CG/game related things. They look quite attractive to me, so much more neat and less bloated than c++. Much more modern I'd say.

Since you don't expect to create anything awesome anytime soon, C# will do the job for now. You'll have to get familiar with frequently occuring problems and concepts in game programming in order to become good at it. These problems and concepts should mostly apply to just about any language/framework, so it really won't matter a whole lot which language you use at the start. Similarly with programming languages in general; the majority of skills can be transfered between languages.

I personally recommend C# over C++ unless you have a specific reason to choose C++. C++ is a very powerful language, but it also requires a lot of effort and practice to use it properly.
