>tfw racking my brain trying to average 2 ints in Brainfuck
I just can't think of a way to get to half an odd number since continuously subtracting 2 would eventually get me too far at -1, and BF only checks for 0

>>52342611
doing it in brainfuck is the hard part, there doesn't seem to be much on division

>>52342611
If you average two numbers, say 5 and 7 it's pretty straight forward. Just (5+7)/2 = 6, yes? But what if you were dealing with numbers that might exceed the type bounds? You'd probably try 5/2+7/2 but that'd give you 5. You want to average two ints but be sure you'll never exceed the size bounds of the input type.

I need to add logging and testing to my shit but I don't know what to log, what to test, who I'd be doing that for, or for what purpose, or why I'm even programming anything in the first place if no one will ever use, maintain, care, or even know about anything I ever do or say.

How do I divide an odd number in 2 in Brainfuck?

>>52342732
does brainfuck have shift right

>>52342732
with an accumulator loop.

>>52342763
No, it has addition, subtraction, while not 0, increment pointer and decrement pointer

>>52342785
que?

>>52342785
that sounds to hard fuck programing

>>52342705
surely there's some logging and testing you can do if you "need" to do it

>>52342809
could you do something like

while not 0 (x)
{
while not 0 (x-1)
{
x-=2
}
}

>>52342834
the inner loop could also skip 0, if x-1 is odd

>>52342834
NICE BRACES DORK

>>52342512

// a / 2 = b
while (a--) {
    if c == 0 {
        c = 1
    } else {
        C = 0
        B++
    }
}

Should translate to brain fuck. Only for positive numbers

>>52342912
>if c == 0
Your only check is "while not 0", there is no "else" either

In the same way, I checked cell 6 was 1 and executed different code if it was, I could do the division as easy as

 [-->+<]

but check that if it's 1, I subtract 1. This way the next loop evaluates to 0, and I can get ready to print. Will do it after I shower

Anyone here know how to use JSON.net?

I'm trying to parse out a JObject so I can store it in a less shit format, but I have no idea how to access each individual token and only the first value in that token.

This is an example entry...
"DIPLOBLASTIC": "Characterizing the ovum when it has two primary germinallayers."

And I want to convert that to a data object like this...

    public class DictionaryObject
    {
        public string Word { get; set; }

        public DictionaryObject() { }
    }

>>52343596
yes
in my experience, most good programmers seem to use emacs / vim or another editor
the only exception to this would probably be the games industry, where people mostly use tools made specifically for the engine
also sometimes people use an IDE for GUI toolkits, because the way some of them are set out makes it pointlessly retarded to position shit manually

>>52343628
But I only want "DIPLOBLASTIC" without quotes.

I thought about just cutting the string at : and remove quotations but I was worried about horrendously inconsistent results.

>>52343513

>>52343596
no.
using an IDE should make it easier to work with the code, especially if you didn't write all of it.

Creating a new file -> create new file + add to git + add to cmakelist

Renaming a variable -> rename all the calls to it rather than search and replace

autocomplete is based on the available variables rather than the words you have written.

clicking on the function call can take you to the implementation

As I see it, an IDE is very useful if you accept that it can do a lot of stuff for you.

You can get a lot of functionality from a good text editor and sometimes this is enough.

>>52343513
It depends what 'learn' means. You could probably pick up all of the basic shit in mere hours if you know another programming language, but like any language, it would takes weeks to months or even years to learn all of the intricacies of it.

What's the best way to get the current thread number in JS, /dpt/?

This is what I came up with:

document.getElementById("postPassword").parentNode.childNodes[3].value;

It works, but I don't like the look of it.

So i'm trying to get the basics of structs/prototypes/involved calls in C, but when I run make I'm getting an error message that isn't very helpful:

error: argument #1 is incompatible with prototype:
prototype: pointer to struct fooBar {pointer to const char foo, unsigned int bar, unsigned int til}

argument: struct fooBar {pointer to const char foo, unsigned int bar, unsigned int til}

(and of course there are more details like the specific lines in my code with these.)
They look the same. Any general tips on how to write the parameters correctly and such?

General tip for prototyping: Don't.
Obviously you have to if your function to going to be used in another file, but for everything that is local to the file, just reorder the functions so you don't need any prototypes.
When you do prototype, literally copy-paste your function definition and put a semi-colon on the end.

document.getElementsByClassName('thread')[0].id.substring(1, document.getElementsByClassName('thread')[0].id.length)

It's not like the same wouldn't apply if you tried doing the same stuff in Brainfuck (except you'd have to handle all that encapsulation interaction yourself, not just learn about a library that does it for you).

So in Android you have activiities which are the GUI

What? Did you expect an action-thriller or something?
It's a programming textbook, and one of the more interesting ones at that.

Can someone help me with some D?

string[] foo() {
  string[] output;
  output[0] = "";
  return output;
}

gives me a range violation (which it probably shouldn't, because this is dynamic array syntax as per the documentatioon), but

string[] foo() {
  string[123] output;
  output[0] = "";
  return output;
}

gives me 'escaping reference to local output'
how the fuck do arrays even work in D?
bonus:
ideally I want

string[] foo(string str) {
  string[bar(str)] output;
  output[0] = "";
  return output;
}

int bar(string str) {
  return someNumber;
}

but that gives me 'variable str cannot be read at compile time'
at first I thought it was worried that bar() might be negative, but it doesn't work with uint either

I love D, but I keep getting these weird errors that don't seem to make any sense. I don't want to have to go back to C++

>>52344028
I assume your problem is passing the objects from one activity to another. You can pass them to other activities by making them implement Parcelable and add them to the activity intent. A less elegant options is to store them in a singleton.

Hey friends, need your help.
I am trying to consume Rotten Tomatoes' API on Android, using Retrofit+Gson, but I am getting an exception
(java.lang.NumberFormatException: Invalid double: "") thrown by Gson,
I am suspicious the Json the APi is giving me is wrongly formatted, since I tried another API with the same code I have and it worked. Can someone give it a try and see if my suspicion is correct?

Yeah I know how I'd actually go about checking whether or not it has a value I don't want.

Is something wrong with global variables?

>>52344489
Unless a variable needs to be global, don't make it global.

>Is something wrong with global variables?
>in short (under 300 lines) scripts should I actively try to avoid them, even if its more work
Yes, absolutely.

>and I feel less readable?
It may be less readable *for you* because you already understand the code. I can assure you it makes the code easier to understand to anyone not already intimately familiar with what it does. Which includes you in three months.

>>52344489
If it's throwaway code, who fucking cares?
For anything else though, they need to be used with extreme caution. Global state can seriously fuck with the extendibility of your program and can make it very difficult to reason about.

>>52344530
255 and 0

>>52344489
functions also are global variables so we should also forbid them and program everything in the same block (a la basic)

>>52344438
Will give it a shot and see what happens.
If nothing works i guess I will have to find another API.

>>52344559

>>52344565
>Function are variables
In languages that aren't memes, they are not.

>>52344576
but anon
the average of 255 and 0 is 127.5

>>52344598
In math, yes. In integer arithmetic, no

>>52344608
The (arithmetic) average of two integers is not an integer

ergo the average is not a part of integer arithmetic

>>52344628
You are talking about arithmetic with integers, I'm talking about integer arithmetic. An integer division yields an integer. A round function that takes a float returns a float even if it's already an integer.

>>52344574
Glancing at the thing I can't see why you'd even need to generate a model.

But I use an API that simplifies my JSON stuff massively, I can just create a data object with relevant properties, define a collection of that data object and just slam the entire thing into that collection in one hit.

And even if it hasn't got a property name I can just use a "JObject" and navigate via keys/values.

I'd recommend looking for a similar API instead of writing it all, seems like it's more hassle than it's worth to me.

>>52344641
integer arithmetic takes integers and returns integers
But the average of two integers is not an integer
ergo the average of two integers is not integer arithmetic

>>52344669
And the division of 2 numbers is not always an integer
Yet integer division still yields an integer

>>52344679
Integer division is not division

>>52344652
By API you meant Framework?
I didn't write the API, I am just trying to consume something on my Android app. The idea is to have a screen showing the latests movies, one for the movie's details and some movie searching, nothing too complex.

>>52344694
Then integer average is not average

>>52344708
There's no such thing as integer average

>>52344704
Sorry, yeah. I meant framework.

Get a JSON framework that does all the heavy lifting and then just create a container for each individual object and slam all your data into that.

Makes life much easier that way, you can just run the JSON call again to refresh the data and you have it all stored locally to do with as you please.

I imagine the way you're currently doing it relies heavily on the code being absolutely airtight, where as with the JSON.NET framework I literally just deserialise whatever the hell JSON I like however I like.

>>52344748

>>52344837
>prevalent in most languages
>good, correct or appropriate

>>52344849

Any Scandinavian fags out here? Is Valkyrja Norwegian for Valkyrie?

>>52344849
To add, you still didn't combat the claim that integer division was a thing. Even if it wasn't in your language of choice, denying its existence meant you're just being retarded, or you're making claims with no prior research

In python does pickling two objects with the same structure and data result in the same text? That is, is there any information about the pointers, creation time, last modification etc. stored?

>>52344772
Retrofit and Gson is what I use to do the heavy lifting to me. Gson converts automatically the JsonObject to my POJO and Retrofit "converts" the API endpoints into an interface. It works like a charm most of times, but since there's something wrong with this API it's giving my this headache. Guess I will just simply search for another API and forget about this shit.
Anyway, thanks a lot for the help fellow anon.

The problem is, I can't think of any cool projects to actually do with said library. Any ideas?

>>52344912
If that language has that feature, then that feature exists. Whether it's a widely used term is up to its influence in programming. Integer arithmetic is a useful concept as float operations are more expensive.

Dunno. I just heard one of the advisors currently works with TensorFlow, and said learning to work with it would be a great course work and a great opportunity to learn, so I kinda went along with it. I don't really have much knowledge about machine learning, but I'm reading a book about it currently.
In any case, the problem is, I still don't really have any perspective on what cool things you can actually do with machine learning. I just picked it because I had to pick something, or I would never start doing anything, and now I'm kinda confused on what are the actual capabilities of machine learning.

>>52345766
Like I just figured it out myself so it's probably only the tip of the iceberg

but you can match the pattern of arguments like:

(macro (x y z) ...)

where the macro takes an indefinite amount of three argument lists, and the first element of each of those lists can be operated upon as x, the second as y, and the third as z.

so if your macro said:

(+ x ...)

and you ran

(macro (1 2 3) (100 200 300) (1000 2000 3000))

it'd return only the sum of the x's, AKA 1101

sorry for the trivial example, but it came in super handy for a more convoluted program I was grappling with

Why does C have anything other than ints and floats? It's literally retarded

>>52346428
because you can define "true" to mean whatever you want, not just 1

for example a list can be true if it has elements, a string can be true if it's not empty, an int can be true if it's not 0. Being able to define this gives you clearer concise code

Why do I need to include stdbool?

>>52346578
To be more correct, it calls my kernel's first syscall with '103' as argument 1 and '1' as argument 2. My kernel then executes this by sending charcode 103 to the program's designated stdout, which in this case is my terminal.

It is.
Well to be more specific, they're reverse-syntactic sugar, as they actually have less functionality than ints.
>Why do I need to include stdbool?
You don't. It's for usability's sake if you're a pythonfag and can't wrap your brain around how memory stores variables.

>>52346574
Because the same person didn't say both things and so can't have moved the goalposts from one post to the other?

How are bool and char any different?

>>52346677
sizeof(char) is always one. sizeof(int) is implementation dependent - on my machine it's four.

No. The C norms say that printf prints to stdout. We do not care about your specific implementation of C.
