You have been visited by the crossdressing C programmer of Shimoshina Academy!
Good performance, triple indirection, and tail call optimization will come to you, but only if you post "Keep overflowing the stack, Hime!" in this thread.
What is objectively the best genre of music to listen to whilst programming
>>54096898
Why care about tail call optimizations, when I could just write it as a loop?

Hey /dpt/, what`s the best way to tokenize a lisp string? My strReplace function isn`t putting spaces around the brackets so it isn`t splitting the string into tokens properly...vector <string> tokenVector;
void strReplace(std::string& str, const std::string& from, const std::string& to){
if (from.empty()) return;
string::size_type start_pos = 0;
while ((start_pos, str.find(from, start_pos)) != std::string::npos){
str.replace(start_pos, from.length(), to);
start_pos += to.length();
}
}
int tokenize(string chars){
try{
// convert string of chars into list of tokens:
strReplace(chars, "(", " ( ");
strReplace(chars, ")", " ) ");
char_separator<char> sep(" ");
tokenizer< char_separator<char> > tokens(chars, sep);
BOOST_FOREACH (const string& t, tokens){
cout << t << endl;
}
/*

Would you rather use a vector or a hashmap to store arbitrary amounts of input data?
>>54097575
It depends.

>>54097474
>Have no idea of license terms, just heard PyQt is somewhat restrictive if I want to sell it
Normally, Qt is licensed under the LGPL, but has commercial licenses available for pay. PyQt is a port of Qt to Python, and is licensed under the GPL, but has commercial licenses available for pay. So basically, unless you pay up, you have to GPL your application.
>Currently I'm learning this: https://python-gtk-3-tutorial.readthedocs.org/en/latest/index.html is this the same as PyGTK?
No, actually, and by the looks of things, you've got the better library there. PyGTK uses GTK2, while PyGObject (which is what your tutorial is using) is using GTK3. Both are LGPL and will serve your needs fine.
>Just found electron, and wanted to check it prior to keep GTK
Using electron is like using a butcher knife to hammer a nail. Wrong tool for the job.

What's so complicated about it?
>>54097657
the fuck does that iota shit do?
>>54097672
iota(n) generates the range [1..n]
>>54097681
whoops, it's [0..n-1]
you can specify the start too if you want
>>54097672
In this case I basically just use it to do the equivalent of a for loop
>>54097681
so it's juststring output = "";
foreach (x; 0..3)
{
foreach (i; 0..uniform(4, 8))
output ~= vocab[uniform(0, $)] ~ ' ';
output ~= '\n'
}
?
I actually don't know whether you can do 0..foo() or if it has to be a compile time constant, but in principle this is the same, right? Just less expression oriented
>>54097644
God bless you.
>>54097745
basically
also I'd be surprised if you couldn't do ..uniform, but it might be one of the things compile time D can't do because of bullshit (like manipulate maps, or use regex)
>>54097745
I think there's a function somewhere that lets you pick a certain number of elements from a range (which is what I should have done) but I can't figure it out
>>54097790
If it defines the slice operator, that would be the easiestfoo[1..5];
alternatively, std.range has drop(range, size_t) to remove n elements from a range, and take(range, size_t) to take n elements from a range

Sequence is similar to Recurrence except that iteration is presented in the so-called closed form. This means that the nth element in the series is computable directly from the initial values and n itself. This implies that the interface offered by Sequence is a random-access range, as opposed to the regular Recurrence, which only offers forward iteration.

i know the bracket is missing, and i have no idea where the spoiler tags came from

Prototypal inheritance was awesome. You only ever needed a base class when it became to share stuff. In a good JS program, you rarely see user created prototypes. Soon though, a simple two state button will probably end up with 3 subclasses...

Obviously depends on your taste, but I'd suggest something without too much going on.
I like metal but I don't get how one can listen without getting distracted by all the elements and noise while programming. With that being said, you still want something with energy.
Minimal techno, deep house, psy-trance, liquid dnb are all great (if you're into electronic stuff).
If you like like instruments, try indie pop. Find a dank compilation on YouTube.
Personally, I love MajesticCasual (YT channel, chill house).
Clams Casino, Ratatat, XXYYXX are also great. They're (mostly) instrumental.

I made a tool to help me visualize translations and rotations. I setup whatever operations I want in an array which can then be stepped through so I can exactly what each transformation does. My original idea was to create a shader debugger but that's a much larger project than I care to admit. Also, the step descriptions are added manually so I could end up making mistakes there. I may want to generate the descriptions from the code somehow.

/dpt/, I need some advice.
I want to write a program that would quietly run in the background on a Windows PC and expose its filesystem to a remote server (allowing to view the directory structure and download files from it).
Basically I need SSH+SCP.
Does something like this exist for Windows? I'll write it if it doesn't, but I'd rather not.
show me any example of a kid that picked up programming in a reasonable amount of time and learned it well enough to write professional-quality software. or any kid at all that can write GOOD software. even carmack's kid only did some very simple babby engine stuff, so your excuse of not having a teacher to spoonfeed you is moot.

DO YOUR HOMEWORK or post it here
Self teaching Python for work, its my first programming language.
How come when I make a Method I need to reference itself.
For example:class Monster(object):
hitPoints = 1
color = 'yellow'
weapon = 'sword'
sound = 'roar'
def battlecry(self):
return self.sound.upper()
Then when I import itfrom monster import Monster
bear = Monster()
bear.battlecry()
I just don't get why I have to reference "self". I THINK I understand why I cant just say Monster.battlecry(), which is because Monster isn't really an object, its just a class I can assign to objects, but I am lost on the "self" part.
Someone have the clever Fibonacci program written in D?
>>54101487
The answer is: Because Python's object system is objectively shit. Also I do hope you realize that all the fields that you defined in the class are shared between all instances of it.
Or in layman's terms: I you make five different Monster objects and reduce the hitpoints of one of them you reduce the hitpoints of all of them.
>>54101429
it's just shit I have to study no actual programming that's why I don't wanna do it
>>54101519
I did not know that.
What the fuck is the point of OOP then? There HAS to be a way around that right?
I just gotta keep telling myself its worth $5/hr more
>>54101545
what the fuck is the point of python is what you should be asking
>>54101545
>What the fuck is the point of OOP then?
The better question is: What the fuck is the point of Python?
>There HAS to be a way around that right?
Nope. Enjoy your shitty programming language.
But it's certainly worth the $5/hour. If your boss is such a dumbass that you have to use Python you can bullshit all problems away anyway.
>>54101561
I donno. The sad thing is I am enjoying the process of coding, but Python feels gross, even as a newbie.
Once I get my $5/hr I might try C++ or something
>>54101545
>>54101583
>There HAS to be a way around that right?
Wait, there is. You have to call all fields "self.hitpoints", and so on.
The other point "Enjoy your shitty programming language." still stands though.
>>54101487
This is just Pythonic idiosyncrasy, most languages have self argument implicitly, otherwise it's the same. Basically, "Monster.battlecry(bear)" = "bear.battlecry()".
And don't listen to >>54101519, Python's object system is one of the best out there.
>>54101519

because it's the best and most correct way to define the procedural interface of an object. people saying otherwise probably never read any PLT literature on oop.
>>54101619>>> class a(object):
list=[]
>>> y=a()
>>> x=a()
>>> x.list.append(1)
>>> y.list.append(2)
>>> x.list.append(3)
>>> y.list.append(4)
>>> print x.list

>>> print y.list

You can't be serious. I mainly work with C++ and I'm pretty baffled. Is python really that shit?

This >>54101696 D I P had to write it with a list instead of variables to prove his point.
>>54101487
So that these methods can reference to the current instance within the class, it's the same thing as "this" in C++, except in C++ it's implicit whereas Python does it explicitly.
>>54101736
nah. In Python, static variables are implicit, whereas non-static variables must be written using the self. syntax. It makes sense, even though its more cumbersome than C++.

Please, don't bully.

Of course they are, python is a dynamic language (not referring to dynamic typing here) where everything is an object, even a class is first class value. Like many in this thread, you are confusing classes with instances.

I went Python -> C -> C++
Tried to learn C++ right after python but was too complicated for me, K&R was better to understand, then C++.
I recommend learning some functional programming through SICP but I never got around to it.
>>54102032
>functional programming
nice meme
>>54102032
c++ is also functional - you begin every program with a function void main();
>>54102081
this is what he's talking about
>>54101982
You can do that if you want but for practical reasons the object field resolution semantics of python are
- try to resolve in the instance dictionary
- if failure, try in the instance class dictionary
- if failure, try in the instance class parents dictionaries
- and so on till you reach the root parent.
Those are fine semantics.
>>54102081
>c++ is also functional - you begin every program with a function void main();
It's a procedure, not a function. (read sicp)
>>54101877
Anyone?
>>54102112
>Those are fine semantics.
no they aren't
Why is Python so shit?
Did you know that Guido never read the SICP?
Did you know that Python has no TCO, because Guido thinks recursion is not basic to programming: >http://neopythonic.blogspot.de/2009/04/tail-recursion-elimination.html
Did you see the hack he proposed as "just as elegant" if you want TCO:
>http://neopythonic.blogspot.de/2009/04/final-words-on-tail-calls.html
Did you know that Python has no multi-expression lambdas because Guido didn't know how to extend the whitespace-based syntax of Python to nicely include them?
>http://www.artima.com/weblogs/viewpost.jsp?thread=147358
Why would you defend a language which doesn't have a feature as elementary as multi-expression lambdas because the creator could not figure out how to make them fit?
Why would you defend a language which makes higher order functions almost useless and actively discourages functional style programming, since you don't have multi-expression-lambdas?
Why would you defend a language of which creator doesn't understand the importance of TCO?

some languages like python and haskell are horribly designed and terrible to use, and have bad performance, compatibility issues etc
>>54102316
Just because you can, it doesn't mean you should. Some languages are better suited for a set of problems than others. But there's always the fanboy that instead of treating these languages as tools, they treat them like a holy thing that should have its honor protected from the infidels, hence the arguments.

I'm not talking about new shiny stuff here. I'm talking about languages that have been around long enough to at least stand the test of time. There are people arguing about Python, about C++, about Java, whatever, to see which one is the best language ever. But it all comes down to the problem at hand.
If your problem is to scrap a website, parse its contents and store them in a database would you use C++, C, Java? For me this is the perfect task for Python, Perl, etc.
If your problem is to work with fairly limited resources (say, embedded systems), then you most definitely wouldn't use Python or Perl, but C or C++.
These aren't by any means the only purposes of these languages. I'm just giving a general example.
>>54102623
Or just use Lisp everywhere. It's the best language.
