url.rewrite-once = (

Not the anon you were answering to but this implies that s is a function that returns a function, right?

Catching up on chatbot stuff after a data failure causing me to lose about six months worth of work.

Basically, wrote in the capacity for concise "yes", "no", and "maybe" statements with meaning derived from conversational context, so that verbose imperative statements aren't necessary all the time.

Hoping that with this in place (and a bit more functionality revolving around semantic inquiries on the part of the system next on my list), I'll have the bare minimum foundations for taking a shot at discourse-driven unstructured natural language learning.

Though I sometimes wonder whether this bloated implementation is worth it. But hey, it's here, and I'm always free to experiment with other approaches on the side.

Excluding differences in directives and syntax and stuff, do all assemblers ultimately produce the same binary from the same assembly source? Do some assemblers try to optimize your code?

>do all assemblers ultimately produce the same binary from the same assembly source
Basically.
>Do some assemblers try to optimize your code?
I've never heard of any that do. 99.99% of code that assemblers receive is already optimised by compilers, and when a human writes assembly code, there is usually a specific reason and/or special instructions that they've used, so they can't have an assembler fucking that up.

Could a struct in C have function pointers as variables, and therefore effectively be a class?

>>57763814
Sure, but there is no point, and that would only hurt performance.

I learned C++ first, probably unfortunately, you might have to explain that one.

Why is OOP a considered bad paradigm? I get that a lot of people use it terribly, but that doesn't make it intrinsically bad.
Is it objectively terrible other than how people use it?

>>57763908
No, VIRTUAL methods are like structs with function pointers - because they change depending on the instance.

Regular methods (*and virtuals) just take an extra parameter

>>57763908
>Do function pointers hurt performance?
Usually, yes.
- They make your struct bigger (more copying, more cache space taken)
- Compilers usually can't inline them
- Extra dereference to call the function

They have their uses, but this is not a good one.

How do you set unusual size types in C?

This isn't true - well, it's true that the binaries will be almost the same, but to say that the binaries are the same - as in hash-to-the-same-value kind of same - is false.

>>57763661
Nope, not always. The problem is not everything is quite specified exactly. One example is labels. What address does a label point to when you write it in assembly? The programmer doesn't have to care, much like higher level languages. But it turns out that in x86 (likely every other architecture worth its salt) the size of a jump instruction varies depending on how far you have to jump.

It's actually a bit more complicated than that, ( http://x86.renejeschke.de/html/file_module_x86_id_147.html ) but the important thing is if you don't have to jump very far, x86 has short, relative jumps which are faster and take less instruction cache.

So here's the problem: the assembler can't know for sure which type of jump it can use just from one pass. Using better jump instructions actually makes the code smaller, which can lead to being able to use better jump instructions elsewhere. So this becomes an optimization problem - which some assemblers don't bother to solve.

These types of "variants" of instructions are all over the x86 architecture. For "simpler" parameters (or simply for archaic reasons), certain instructions can be encoded in a special smaller way than if you used the "generic" format. The whole setup is messy to be quite honest. I'm going to brush up on my x86 encoding and give you an example of encoding the same add instruction two different ways.

>>57763929
>but that doesn't make it intrinsically bad
Sure, misuse doesn't make it intrinsically bad, but that doesn't mean that it's not for a different reason.
The reason it's shit is because it encourages shared mutable state in programs, making them hard to reason about, and leads programmers to design their programs in ways that don't fit the problem (or any problem).
https://www.youtube.com/watch?v=QM1iUe6IofM is a pretty good critique of the paradigm.

>>57763976
>but to say that the binaries are the same - as in hash-to-the-same-value kind of same - is false.
I never claimed that. I said "basically". I meant it's the same for all practical purposes.

>>57763974
You can't.
You will have to use a larger type and just ignore the extra high bits.

do people unironically watch sexual themed cartoons like this and get off to it?

>>57763996
>>57763974
Actually, I want to make an addendum to what I said about unusual types.
You sort of can make unusually sized integers, but only as part of a struct:

struct int13 {
    unsigned val: 13;
};

However, these will be represented as an int, so there will be no space savings.

The feature is called 'bitfields'.

Good one, idiot.

I've compiled some c++ programs with visual studio's visual c++ compiler but it doesn't work on other computers.
What should I do?· change the compiler?

So DPT I'm planning on learning programming in my free time at work, my boss said he's fine with this as long as I only do it in spare time anyway he's said I can't install any software on the system (vim & git) so I was thinking of putting codebox and git on my server this way the files are always saved on my server and I can just SSH in git push etc. anyone here use codebox or have used it? I know this isn't the perfect setup but will it be good enough?

>>57765321
Either link statically against msvc libc/c++ or tell people to the install the vcredist for whatever visual studio version you're using.

>>57765321

Are you running same program same operating system or same program different OS? Former should work unless you've got some issues with dynamic linkage. In the latter case, you're an idiot. Only x86 Windows understands an .exe compiled for x86 Windows, unless the target OS is using some sort of compatibility layer or emulator.

On a slightly related note, if you ARE trying to port to other operating systems, I would suggest using a different compiler. You probably shouldn't be using VC++ either way, but you can't use it if you want to target, say, Linux or Mac OS X. You'll need Clang or GCC. The former has bindings for being integrated into Visual Studio, the latter is more mature and is able to target quite a few more operating systems and CPU architectures.

struct foo { int x; };
void foo_method (struct foo* f) { ... }

struct foo q;
...
foo_method(&q);

Rather than

struct foo {
  int x;
  void (*method) (struct foo*);
};
void foo_method (struct foo* f) { ... }

struct foo q;
q.method = foo_method;
...
q.method(&q);

unless you need the ability for the method to be dynamically reassigned (which would require a function pointer anyways). It should be very obvious why the former is much more simple.

>>57767170
the first is completely different than the second and none of these are methods.

>>57767492
what does the language have anything to do with the programmers

>>57767492
Academic language (naturally more leftist), mostly used in industry by small shops.

which is better:

user = input()
if 'key1' in user:
    function(arg1)
elif 'key2' in user:
    function(arg2)
elif any(x in user for x in ['key3', 'key4']
    function(arg3)

or 

dict = {'key1': function1, 'key2': function2, 'key3': function3'}

user_words = input().split()
for word in user_words:
    if word in dict.keys():
        dict.get(word)
    else:
        pass


I much prefer the second way as elif statement after elif statement quickly gets out of hand but there's issues with storing two keys for one value.

Hello guys, can I have some help? I'm just learning C# and already trying to work on something to my uncle's store.

Basically I have some .txt files generated by a program as the following: http://pastebin.com/TbwQr4uE

How can I manipulate the data from this txt file? I was considering using StreamReader. Pass each line to an array and then turn the data into a CSV file.

Okay, I have no clue on how to do this or if this is possible. You don't have to give me all the code of course, I have been trying StackOverFlow and some google research but I couldn't find a tutorial about this.

Can someone enlighten me? Which methods can I use etc.

How useful is IRC for programming? I mean every programmer I've ever spoken to about chatting and stuff says they use IRC and I have a spare server so I'm thinking of setting up a bouncer and getting into IRC (using IRRSI on windows and linux) should I bother? how newbie friendly is it? and what servers/channels should I be using?

>>57767833
It's really a symptom of you using (f)scanf. %s doesn't know about the size of the buffer, so it will happily write past the end. It's the exact same reason why gets() was so shit and removed it from the standard.
The 'fix' is to use %4s, which will read a string of at most 4 characters. Note, this DOESN'T include the null terminator, so the buffer must be at least 5 characters big.

>>57767867
No, that's exactly it. You haven't left space for the null terminator. So when you read "time_of_day", it will go past the end and read "hometeam" as well.

>>57767540
>>57767843
You don't have to have a service; as long as you have a running process, you can detect keypresses.

C++ noob here. Explicit instantiation vs. specialization. What is the difference?

To me everything points to the opposite.

>>57770211
Fair enough, your top kek says more than real evidence ever could.

>>57770230
If you think of a template as a function, instantiation is calling the function with a particular value and specialization is having a branch inside the function.

>>57770239
I assume you never went to college. I assume you neither read math related papers.

>>57770208
>Folding is recursive. That definition is totally incorrect.
I'm sorry to be so dumb but if you were to encode 3 as a church numeral, it'd look like

Succ(Succ(Succ(Zero, S), S), S)

, right? Why exactly are the other arguments needed? I have the feeling that what's bugging me is that I'm trying to mix both abstract and concrete representations but I can't exactly put the finger on what I'm visualizing wrong.

>>57770278
No, just

Succ (Succ (Succ Zero)))

. Then applying z and s gets you

s (s (s z)))

.

What does the editor''s note say trapfag?

>>57769681
Set a goal that's quite high but has many 'this is useful' breakpoints.
People often suggest games because they're completely arbitrary. You can make something like asteroids easily but you can also make it a very large and complex project (mmo endless world asteroids in 3D with rpg elements).

But you can do something like solving a problem you have. Me for instance had issues sorting my porn effectively. So I started with a simple program that moved images between two folders based on shortcuts (1 for 'hentai' 2 for '3D'). It eventually became more advanced. Didn't just sort images, did searching and playback in videos. Deferred moves for performance reasons with optional in the background moving. Generated 'notable scenes' from videofiles so I could recognise them better etc etc.

That way you can actually push yourself without going through the easy bits again. And you learn to effectively evolve applications. Which is what you do as a programmer in the real world 99%of the time.
You rarely start from scratch.

>>57770302
That list is like every phd woman ever in the history. Most of them are people like me: know a lot of maths and teach in academy and stuff, but never did nothing big.

>>57770245
I don't like this explanation.
It's more about allowing the compiler to work with a more specific case. Where specialisation lets you implement for a specific type and instantiation lets you partially specialise a specific value. (I.e your pow function might not handle the pow(n, 0) case well. So you do partial specialisation and have it always return 1. You'd probably also want to deal with cases where n=0 and exponent = 1then and assert that's incorrect)

>>57770302
https://en.wikipedia.org/wiki/List_of_men_in_mathematics
Do you know what it means?

>>57770359
So? The implication made was that women can't do maths.

>>57770302
Maybe you should see the success rates per student of x gender in pure maths or whatever.

Tends to be overwhelmingly in favor of women. But that goes for almost all degrees. Simply because women are better at academia and society hates men.

>>57770376
What's wrong with my analogy?
>specialisation lets you implement for a specific type
i.e. branching on the type and doing something differently
>instantiation lets you partially specialise a specific value
That's not even right.

>>57770390

>hurr I can multiply every number lower than 100 with 11

>>57770404
>that's not even right
Well you can do it without implementing but that gives a fairly limited usecase.
And your explanation doesn't really fit that usecase.

m80, I only asked "because women are better at maths?" to probe the anon claiming that Lisp is a women's language as it is it based around the evaluation of mathematical functions.

Instantiation is whenever you use the template, like std::array<int, 16>.

>And your explanation doesn't really fit that usecase.
Why? Templates are just functions from types and integers to types.

>>57770245
Thanks!

>>57770412
That doesn't make sense, being bad at maths doesn't count as being able to do maths. You're either good at it or you aren't. Historical evidence proves that women can do maths.

Unfortunately I now have a followup question.. Why not just make a non template version of the function or overload an already made one instead of using specialization. Sorry if I missed something pretty blatant that would tell me why just overloading instead of using specialization is not a good idea.

I can also play drums, it's easy, but I will never be able to be in a band.

>>57770645
Just keep with the analogy. Why do you add a branch in a function instead of writing the new result out wherever it's needed?

>>57769777
*fixes your code*

>57770571
to the filterfag you go :^)

>>57770667
Maybe the issue isn't >women logic but rather that you're using the wrong words to express what you mean?

>>57770667
Did you intentionally come up with the worst possible metaphor? Being good or bad at playing the drums is an opinion that, while there is a consensus about what makes a good drummer, is still just an opinion.

There is no such thing as being a "bad" mathematician because if you cannot work out the correct solutions due to a lack of ability then you're simply just not a mathematician. Bearing that in mind, there were female mathematicians. So what would that seem to imply? Now whatever bullshit, smart arse, evasive answer you provide will not disprove your statement that women cannot do maths.

>>57770728
I may just be retarded, but is it just for the sake of simplicity? I quite honestly cannot think of any other reason to not just overload. I read some more from the book and have not found an answer yet.

It's for the sake of reducing duplication.

For example, std::vector<bool> is specialized to be more efficient by packing the bits together instead of using an array of bools. If this was an entirely different type std::bit_vector or something, a type templated over T with std::vector<T> inside would not be able to benefit from it. You'd need to specialize it (or continue with not specializing and make a whole different type altogether).

">women >maths" does not imply that women cannot add 2 and 2 together.

It implies there are little to no notable female mathematicians, and potentially only that the average female has much less of a propensity to learn and pursue maths than the average male.

>>57770965
Great, so you're ending this debate by being as retarded as possible.

What is that even supposed to mean? That she's bad at maths because she can get those sums correct? Are you implying that this fictional person believes they're a mathematician based on that ability?

>>57771024
that's what happen when a brain is flushed with feminist propaganda man

>>57770997
Okay. That makes more sense, thanks.

>>57771024
If that statistic is correct, how do we know that's proof of their lower intelligence. Because by acting like such a cock, you've provided the counter evidence that women are just as capable but they feel pressured out of mathematical-oriented academia by egotistical tosspots like yourself.

>>57771087
I'm not the anon you're arguing with.

It is true; there are much less women in mathematics than men.

I never implied or otherwise said women have less intelligence.

However, women have less geniuses than men, as well as less retards; their bell curve is more centered and less extreme than the IQ distribution of men.

Women are also actively pursued with scholarships and affirmative action favoritism in under-represented careers and jobs, to the detriment of a potentially more qualified candidate, in some cases.

By correlation, niggers do almost as bad as women in science.

I can't honestly tell you what the fuck am i doing. but here.

#include <iostream>

        static int f2();
    };
    
    class te {
    public:
         void test();
    };
};

template<int a> void T<a>::te::test() { cout << a << A::f1() << A::f2() << B::f1() << B::f2() ; }

template<int a> int T<a>::A::f2() { return a - 1; }
template<int a> int T<a>::B::f1() { return a * 2; }
template<int a> int T<a>::B::f2() { return a * 3; }

int main() {    
    T<2>::te t;
    t.test();    
    cin.get();
    return 0;
}
