Lisp is the most powerful programming language.

>>59947267
right now i'm going through cracking the coding interview in python. this summer i'm going to be doing a research internship with machine learning so it'll be interesting how that turns out

is python supposed to be the most basic programming language? it seems everyone learns it as an intro

>>59947303
No.

next() in java only reads until a newline, is there something that reads everything in a txt file, newlines included?

>>59947300
Good luc man!

>>59947303
Not necessarily BASIC (although that is a programming language ;) ), but it is easy to pick up because it hides a lot of the nitty-gritty features of languages like C, C++, or Lisp. It's quite easy to do what you are thinking with a python script, making it beginner friendly.

>>59947300
damn that sure sounds interesting.

>>59947303
Nah, but simple languages are for children and teens who aren't in college yet.

Like logo and shit.

do people actually sit together and study?

being near people is distracting

>>59947312
i don't think so, i know in python they have file.read(). in java i think you need a loop

>>59947330
Shit yeah it's fun, we used to quiz each other and explain each other stuff, not sit in silence and study like weird mormons.

>>59947330
go to your nearest library, of course people sit together and study. they do it for group work or just studying in general. i prefer studying at home now though, got all the food and coffee to get comfy

I mean, looking back, I kind of regret not going into study groups since the very beginning. I was doing pretty miserable both grade-wise and emotionally on my second year.

Study groups both improved my grades and my mood.
If you find you can't concentrate when doing your homework and studying, do try doing it with friends, can't recomend it enough.

>>59947467
that's the hard part isn't it. they were study groups organized by the science association, it would have one older student mentoring it, and others who signed up online.

>>59947414
That one is simple. Just call the unbound :+ and Lisp will complain.

>>59947474

Lisps pride themselves on their strong metaprogramming capabilities, but Ruby has a lot of interesting strengths. They can add and remove methods from objects at runtime, create types at runtime, modify types at runtime, and more. Where Lisp has macros, Ruby has a lot of... quirky tricks up its sleeve.

>>59947485

Nope!

>>59947518

How would you unbind the + function in Lisp?

Yes. C++ is a language of video games.

>Engine i'm planning is Unreal Engine 4, I heard Unity is cancer towards the industry.

If you need a 3D engine for your game, you should probably consider making some smaller scope games first.

metaprogramming seems like a bad idea and always annoyed me when I couldn't look up where a method was defined

I still like ruby though. If you like lisp more than ruby you're a tryhard imo.

>>59947759
UE is a superior engine, but Unity is fine provided you don't just use all the stock assets, world building, and physics, which is main reason everybody loathes it

Lisp is more cyberpunk tho

Metaprogramming is a programming technique in which computer programs have the ability to treat programs as their data. It means that a program can be designed to read, generate, analyse or transform other programs, and even modify itself while running.

>>59948028
The whole point of metaprogramming is to reduce rewriting code, which is a very good thing from a maintenance perspective. Just don't abuse it.

What are the best books about cybersecurity and remaining in the dark on the Internet?
Some information about me got leaked and a part of my personal data has been revealed. This happened because of my carelessness, and this is now a good reason to learn and care about my privacy.

What minor things I did so far:
>stripped down my facebook to almost zero I only use it as my "newspaper"
>switched to BlackPantherOS because I had a CD of it
>I started to use Google services indirectly

Now I realise I cannot be entirely alone cause I do not have the ability to gain control of the servers of the services so I just want to achieve the goal that makes me partially invisible from the general population.

What steps do you take to isolate yourselves?

>>59948689
Does anyone know how this sort of thing performs? Can I use this view to do a limited-depth query, relying on PostgreSQL to not compute more recursions than necessary?

ie,

SELECT * from implications_closure WHERE topic = 'some topic id' AND depth < 5;

How good is postgres at graph traversals like this at all, assuming I did a normal WITH RECURSIVE query with depth limit instead of a RECURSIVE VIEW?

I'd use a specialized graph database, but I want to join against some other metadata stored in postgres.

I've found it's the best way to motivate myself and actually learn stuff.

I had a friend that liked to study that way too. We'd sit in an empty classroom or at a study room in the library and continuously explain the material to each other. We'd catch each other's errors and constantly refine and revise our knowledge.

He flunked out of my class and I was unable to find any other study partner. I was actually tempted to deliberately flunk out of my class just to get my friend back. Nowadays I just read class transcriptions 1 day before the test and hope it works, I get an average grade

Eh, I'm more used to Scheme than Common Lisp, which is a bit more limited in that aspect, last I checked. I don't know of any undefine function/macro, and using set! in at least one Scheme variant I use will throw an error for trying to re-write an inlinable procedure.

That said, Ruby is in a few ways inspired by Lisp... along with a few other languages.

I don't want to be a code monkey, sensei.

I've finally decided to actually follow my dreams and try to advance my programming to a sellable level. I'm looking for a list of challenges that I can complete one day at a time ranging from intermediate difficulty to advanced to try and actually get some practical experience, does anyone know where I can get something like that. I'm not very creative so coming up with them myself is not exactly my first choice.

>>59949445

There's not much to C that can really be considered complicated. Once you understand the language features, really, it's just a matter of practice and reading other people's code.

As for algorithms... read CLRS I guess? Or get a CS degree?

>>59949523
I still deciding. Its either going to be C++ or C# as I have experience in both and both are in demand.

>>59949541
The key to achieving your dreams is to set short achievable goals. Before dreaming big, start by saying I want to do X by a date. So you can start with by the end of the week, I will decide what language I will do. Good luck.

>>59949368
This gave me an idea for a simple, little challenge:

Write a function that takes a list of items and return a String of the concatenation of these items. Bonus points if it is generic when using a statically-typed language.

use std::fmt::Display;

fn concat_items<D: Display>(items: &[D]) -> String {
    items.into_iter()
        .fold(String::new(), |con, i| con + &i.to_string())
}


fn main() {
   let items = [12, 134, 234, 1324, 657856];
   let con = concat_items(&items);
   
   println!("{}", con);
}

Except it can't and never does. Not for any complex problem where you'd actually care. I'm sure if you only write small programs with small data loads JIT can help you a lot but not generally.

>>59950189

Then maybe add a smallish layout hint in situations where you know better than the JIT? There's a continuum between static and dynamic anyway, so why let's not fight over this? (unlike >>59950189)

how do i get into graphics programming, specifically for game engines?
i've read GPU gems, and it was helpful, but it's outdated

for instance, if i wanted to implement screen space reflection, where do i go to find out how to do this?
(i have googled it, no significant results)

>>59950249
"Game engines" are just data-driven platforms for games. You're essentially making an actual game, except its extremely configurable. As in, you write code for all the graphical features and gameplay mechanics such as collision and not falling through the ground and walls, but you let the user plug in assets such as 3D models and highly-specific game logic scripts.

>>59950277
i know that
i'm talking about rendering stuff and shaders specifically
i think it's hard to find information on because pre-built game engines come with their own graphics stacks and their own implementations of shaders

i'm just asking for a wiki or something to help me find this stuff

>>59950249
>screen space reflections
Just googled it. basically it's when you see reflections of other objects in a mirror or in water right? That's basically by my intuitive understanding
1 render all the shit
2 flip it with regards to the reflecting surface
3 deform it a bit or some shit or whatnot
4 merge the result back into 1
It's just that they go to unreasonable lengths to optimize it.

Now speaking of googling it, there's a freely accessible talk in the second google result:
http://www.frostbite.com/2015/08/stochastic-screen-space-reflections/
I don't get a single thing because I don't know the jargon, but if you're going into that you must learn that jargon and the underlying stuff anyway, so go do that. No one is interested in spoonfeeding it to you.

>>59950324
You need linear algebra. Transformation matrix and all this fun stuff. No questions ask, that's just how computers do geometry.

>>59950236
>Then maybe add a smallish layout hint
I agree that I'd certainly want my memory layout to be a solved problem the compiler can handle for me, not too fond of a JIT with my experiences but it could be worked around.
Problem is that you can't have "smallish layout hints", you need to be able to specify almost every aspect. You'd also need tools to figure out what decisions have been made for you if you're gonna be able to correct the compiler. On top of that is the problem that makes the JIT unable to figure this out for you. Data layout isn't an easy problem to solve becuase it's dependent on the entirety of the program, in particular other memory layouts. So therte's the issue of matching the JIT with your custom layout. Which I've never tried but it sounds hellish.

>There's a continuum so lets not argue
Anon you're never forced to respond. And a continuum only opens up to more arguing imo.
I don't think anyone should half-care about performance and argue about it is the thing. Suggesting a JIT does it for you without the caveat of being able to take control is simply misunderstanding the problems people with low level concerns face.
Nobody uses low level languages because they think it's always easier they just do it because the situation requires it. Statically typed languages have advantages in convenience but they're often not as well implemented as something like Go. I think if people understood static typing as what Go does then they wouldn't bother with dynamic typing at all.

>>59950329
>It's just that they go to unreasonable lengths to optimize it.
>unreasonable
Not really anon. Most optimizations made are pretty simple too. And there's work on improving the effect without using stupid high resolutions for your SSR.
>points 1-4
Yeah but anon is looking to implement it. He needs more than that.
You need to mention that you reflect against the depth map to sample the screen space.

you missed the point, SSR is just an example

but anyway, that's a reasonable assumption, but this has to be done each frame, and it does need to be optimized as much as possible to reduce frame time

again, i'm not asking for spoonfeeding, i have googled this over and over again and never found any good resources for learning this stuff

>>59950339
i have a very strong background in mathematics, i am confident that i can handle any mathematics involved in graphics

>>59950418

how do i find such papers?
SSR has a few readily-available papers (i did come across that paper you posted), but there doesn't seem to be any good resources for this sort of thing in general

With stack, how do I install a locally package globally?

>>59950349
Solved problem it's never going to be. We just want better tools, like in any other field.

>So therte's the issue of matching the JIT with your custom layout. Which I've never tried but it sounds hellish.
Don't runtime environments already do that? Or maybe I don't get what you're saying....

>>There's a continuum so lets not argue
>Anon you're never forced to respond.
Mate I'm not trying to dodge, I was taunting the shitposter. (not saying it was brilliant.)

> And a continuum only opens up to more arguing imo.
Agreed, and if there is a continuum we have no option but to explore it.

>I don't think anyone should half-care about performance and argue about it is the thing. Suggesting a JIT does it for you without the caveat of being able to take control is simply misunderstanding the problems people with low level concerns face.
What people? Are you in numerical computing? Virtualisation? High performance middleware? I'm curious

>Nobody uses low level languages because they think it's always easier they just do it because the situation requires it. Statically typed languages have advantages in convenience but they're often not as well implemented as something like Go. I think if people understood static typing as what Go does then they wouldn't bother with dynamic typing at all.
To an extent, yeah, it has boxing and untyped constants, which makes it pretty transparent.

desu I'm hyped about gradual typing. Would be nice if there was one language specification to govern them all. Then you use a tolerant engine for that language to make your prototypes, and you do so until it yields the correct result, albeit slowly. Then if you need it, you can switch to a high-performance engine, and add hints everywhere without breaking compat with the first engine. Here's our continuum.

>>59950521
>a locally package

>>59950510
I don't know of any good collected resources. Especially if you don't know what the effect is called (like SSR). But you can often be lead to different topics through GDC talks or as I mentioned references from other papers have proved useful to me.

Most don't tend to lead you to new ground though. It's simply difficult to find. You need to do some clever searching.

>>59950644
>>59950349
>I think if people understood static typing as what Go does then they wouldn't bother with dynamic typing at all.
If you were to prototype a language implementation you would probably do it with runtime typing, because static type checking is decoupled from execution and if you want to profit from it you have to find a way to pass it around, which is unwieldly. There you have Python static typing, which is optional and handled by third-party tools, not by the python interpreter itself. Now, statically typed languages have pros, but I wouldn't say that dynamic ones wouldn't exist if they were better, because that's how you implement reflection, too.

>>59949369
Why not? It's an extra layer of trust and it's only one command line option.

Your question becomes "why can't I reinterpret an uint_least16_t as an int16_t?" which definitely sounds easier to answer. Also please refine the meaning of "I can't" in this sentence because it's vague as fuck. Is it a static analyzer? The compiler, and if so, with what flags?

Use static_cast.
https://ideone.com/O09FkW

>>59951307
both char16_T and int16_t are probably 2 bytes here.

But your example is relevant: you are rawly-converting an unsigned to its signed equivalent. Your compiler is probably uneasy with that because it is undefined behavior as there are many ways to represent signed integers in binary. https://en.wikipedia.org/wiki/Signed_number_representations

Wait no it's forbidden: http://en.cppreference.com/w/cpp/language/reinterpret_cast
You can try:

char16_t c = 'c';
const uint16_t& n = reinterpret_cast<uint16_t&>(c);

I don't guarantee that it will work, but that seems more reasonable given the cppreference page.

This seems dangerous. You're defining an int-sized reference to a memory segment that's only guaranteed to be big enough to hold a char.

                        string[] data = entryStudent.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);

                        students.Add(new Student(data[0],data[1], double.Parse(data[2])));
                    }

                    foreach (var item in students)
                    {
                        Console.WriteLine($"{item.FirstName}, {item.LastName}, {item.Mark}");

>>59950809
I'm not sure but I don't think you should have to reinterpret it manually at all. You should be able to just assign a char16 variable's value to an int16. If your chars are signed, there will be no difference in value; if they're unsigned, overflow will wrap them around to negatives as appropriate. Either way, the byte representation shouldn't change, just as if you'd used reinterpret_cast.

There is no TryParse for a type of "Student" until you implement it.

It's a method on the type.

These methods are all called "Lmao", but they are static methods on their own distinct types. Same situation as "TryParse".

>>59951679
In order for those to have a bit pattern, they must be stored in memory, otherwise it's just register values flying around. by forcing them to be a referenc, you can reinterpret the reference (and apparently that's the only kind of thing reinterpret can do, C++ is weird) into a reference to int16_t, which means you'll access your char16_t as if it were an int16_t.

I guess if you're trying to use reinterpret_cast instead of static_cast, that means you want to preserve the bit pattern rather than the value? Then reinterpret the reference. It's weird but it's so. static_cast will happily convert the value from its char16_t representation into its int16_t representation, especially if they don't have the same bit-pattern

>static_cast will happily convert the value from its char16_t representation into its int16_t representation, especially if they don't have the same bit-pattern
Which is why i'm wary of static_cast. I'm never entirely certain what static cast does to my bits, even if most of the time the bit pattern is preserved.

Why all this fuss over what's just a type cast?

>>59951703
Exactly. We hired a guy once who was an absolute rockstar on paper: a lot open source contributions, side projects, mad programming and cs skills.

Turns out our autistic rockstar was too "uncomfortable" talking to John or to us, literally expected someone to babysit his "genius". He spent his time working on his os projects. Ironically, they were Haskell based lol. Boss was so fucking mad he fired him and a manager right that fucking instant. And told us to never hire anyone who shows any sign of social ineptitude.

How does IComparable work in C#?

I see that i need CompareTo Method for it to work and using it i can sort all kinds of shit

for example, in my Student example here >>59951800
>>59951947

I wrote a Method

        public int CompareTo(Student other)
        {
            int comparsion = this.Mark.CompareTo(other.Mark);
            if (comparsion == 0)
            {
                comparsion = this.LastName.CompareTo(other.LastName);
            }
            return comparsion;
        }

and i can successfully use students.Sort() to sort student instances by mark, but how does it work?

>>59952326
It sorts student by mark and failing that by last name, yeah, and it calls your method to know who has the biggest grades until it's fed up. What do you think is worth asking "how does it work" exactly ?

>>59952326
And additional question, what is considered better, using IComparable or simple LINQ statement to sort your shit?

>>59952336
>I'm busy coming up with something revolutionary right now
I'll put that down as a check

>>59952356
My biggest wut was it lacks any for loops, simple students.Sort() sorts my whole List, and my CompareTo method only sorts 2 instances by their property, i kind seem to find the connection between whole sorting algorithm and my list

>>59952380
Well its applying your comparison function over a range. What use would sort be if it didn't do that?

>>59952358
Surely LINQ, it's immediately explicit what the sort criterion is, it's more flexible, and probably more performant given that a compare operation is a stupid as shit interface to feed a sorting algorithm.*

*: It may need to be called once for each pair of elements and it's complicated to write, whereas a sorting-key operation that yields (this.Mark, this.LastName) as a tuple is trivial and only needs to be called once per student.

LINQ makes it very clear as to what you're sorting by, when you do something like

>because that's how you implement reflection
This needs elaboration.

>>59952515
RTFM

>>59952533
You need runtime type information to know what you're dealing with: if you query

myfunction.defaultValueForArgument(3)

, you might get any type of value that exists in your language, so it's basically a dynamically typed field even in Java. Might call it a boxed value, call it what you want. The trivial way to respond to that is to have a dynamically typed language, like the lisps --- who are the best at homoiconicity, sorry ---; I know some statically typed languages manage to have reflection, but static typing advocates can't not condemn the interface when they see it because it's basically dynamic typing in disguise.

>>59952493
That's what i assumed by i saw before that LINQ is generally slower than basic for loops and stuff like that so i had to ask

So, IComparable is not anymore useful, now we have LINQ?

        wchar_t c{ 0x00ff }; //this works
    //wchar_t c{ 0x01ff }; //this causes file put error

    std::wofstream file("test.txt");

    file.put(c);

    if( !file.good() ) { std::cout << "File put error\n"; }
    else { std::cout << "File put good\n"; }

    file.close();

Why? I have no idea what's going on.

>>59951520
Anon if you're the same guy that asked about how to get the fields of a class specified by name before (to which I answered with a link to Javas reflection tutorial) you shouldn't bother with this. Learn to ask good questions first.
Nobody fucking knows what you're talking about the only way to know would be to google getDeclaredFields and figure out exactly what you're asking somehow. Only reason I have a clue is because I assume you're the same guy that asked horribly before.
https://docs.oracle.com/javase/tutorial/reflect/member/fieldModifiers.html
Read this. Filter yourself if you can't get the API to do it for you. It's very rude to not even try though.
What you could have done to be more polite is find out how to get the field modifiers yourself, conclude that you could filter it all yourself and then you ask us if there's a better way.

Kotlin: is it any good?

I hate Java's fucking syntax so goddamn much and this looks like the dream I've been waiting for.

>>59952644
IComparable must be implemented by the basic stuff: ints, strings, and the stuff you have as the output of your LINQ sort criterions because they need to be compared afterwards.

>>59952639
I don't get your example
What does it do?

>>59952687
Were you intending to quote here?

>>59952727
No, this is an original™ post.

>>59952694
It's pseudocode, but say you have a function with a default value in an argument. (C++ and Python have it) If you have a reflection interface, you should be able to view this argument's default value's. Now suppose this is the 3rd argument, and the getter for default values is defaultValueForArgument. (yeah, really Javaesque) What is the static return type of such a method? The value might be any value that exists in the language, so is it "Object", if that's the name of the root class ?

It doesn't even need to be this complicated: an eval function that can interpret code at runtime:

eval("2+2")

yields 4. but supposing the string isn't known at compile time, what is the static return value of eval ?

In both cases you end up with either the language can't do that, or the return value is a general type, an instanc of which any conceivable value is. In the second case, congrats! You've reinvented dynamic typing, and it shows that abstract algorithms aren't typed, otherwise they wouldn't be turing complete. Type theory is just something we stick on top afterwards. It's useful tho, I'm not saying it's not but it's not essential.

>>59952687
It looks like a better Java and Scala.

>>59952819
Do you mean "the default value for argument number 3"?

Over many years we had many iterations of this library (event processing library). It has many faults and could be done a lot better if we had time but we don't have the time for it nor the time to port all our code built on top of it.

Would it be seen in any way "bad" if I was to make a better version of the library in my spare time using the lessons learned? No code would actually be re-used &c. At the same time I wouldn't want to feel like I'll just get asked 3 months down to port everything to my own library during work, effectively doing all that for "free" which I guess could happen.

I should say we're contractors (Haskell).

>>59952912
Would a better version of the library require changes to it's API?

I do a lot of consulting for companies doing large scale data science or that run long running clustered processes. Julia as a language looks beautiful with keen attention paid to elegance. The issue I see now is that there is not currently large scale infrastructure to support it's use in a meaningful way. While it can be done the barrier to entry is too high for most companies (including some with enterprise budgets.) Once it can be integrated into existing architectures (hadoop, mesos, spark, etc) it will really take off.

Which game engine or library should I use with Java ?

>>59952989
Then you're not going to port everything to your library for free, are you? You'll get paid to do it.

I'll get paid whether or not I write it. The question is more of "how do I write it such that after 3 months of writing it, I'm not paid for 2 weeks of work to port code to it"?

I guess I don't know what I'm asking, sorry.

Or maybe I should put a non-commercial license on it or something.

Guys what the fuck am I missing? Using Processing library.

It literally tells you. Literals are double. You need to write 0.01f for float literals.

>>59953068
>Or maybe I should put a non-commercial license on it or something.
This. If you don't you'll only have yourself to blame.

I guess what you're asking then is would it be bad to re-write the library from scratch under a non-commercial license.
I'd say that's your right, but i'm not any kind of authority on matters like that.

>>59953182
Why?

>>59953133
Interesting, thanks anon, looking at it right now.

>>59953192
Thanks, I'm used to working with regular Java where the only difference is the number of bits available.

>>59953309
That's what he said.

>>59953369
I'm not used to having to type "0.01f" to make it realize that 32 bits are enough lol.

Language: C
I need to use a loop to insert elements provided by the user into an array, however these elements need to be separated in their own slots within the array (so, in case the users types a int with 2 or more digits the program doesn't interpret the first digit as the element 0 of the array and the second digit as the element 1 and so on).
I'm not allowed to use fgets or gets.

#include <stdio.h>
int main()
{
    int i=0;
    char array[3];
    while(i<3)
    {
        scanf("%c", &array[i]);
        if(array[i] == '\n')
        {
            break;
        }
        else
        {
            scanf("%c", &array[i]);
            i++;
        }
    }
    for(i=0;i<2;i++)
    {
        printf("%c", array[i]);
    }
}

To be honest, I don't feel any sort of change to my cognitive functions - this is mostly due to being only aware of whatever I can achieve at any given time.
I can write my own assembler shit, I can work out a few "complex" algorithms, and I can reach myself new mathematical and abstract 'codesense' concepts over time - if given enough time, of course.

This doesn't make me feel smarter. It doesn't feel like my cognition is improved. In fact, I personally believe a clean cognitive mind wouldn't catch itself in the unnecessary conflicts that lend to machine tasks being solved. The real cognitive prowess, in my opinion of course, is being able to drop tertiary un-necessities such as coding... at least for such examples as: forcing yourself to lose personal health and sleep-cycles over struggling to achieve a solution to a code issue.

Losing personal gain in order to solve a problem existing as a non-problem in logically is the real foolish, non-cognitive failure of the self/mind/sociocompliant thoughts. But I goff - we are in /dpt/, the context of this forumic gathering of developers would barely have any kind of personal agreeance to what I've just written, and understandably so. It's just not aware, nor properly contextual.

How do I fix this problem without editing any scripts?

that method I gave would be good for changing individual objects that have values that are strings, but you could change the sed command there to just inject what you've done into the beginning of each script.

If I might offer another suggestion that is more of something to keep in mind going forward: if you take advantage of Python's inherit directory structure you're able to do really awesome things to make your stuff modular:

look at what this guy talks about:
http://mikegrouchy.com/blog/2012/05/be-pythonic-__init__py.html

you could create a program entry point that declares the default encoding for all subsequent modules you write in their nested directory. that way to change a lot of stuff you just modify one file :)

I'm doing something in c++. To make this shorter let's just assume that vector in the following text is std::vector<*whatever>

class foo{
        vector *_v
...
        setV(vector *other){
               _v = other;
        }
};
...
vector a  = new vector;
foo f;
f.setV(a);

This worked fine, I could access the _v in f, but when I changed it so that _v is just an object, not a pointer, and that setV takes a reference to a vector the program later crashes when I try to access the elements inside. i checked in the debugger and the elements inside other in the setter function are all null. Why is this happening? I thought passing references was used exactly for this, to avoid fiddling with addresses when you don't have to.
