R6RS is aids.

R7RS is being split up into standard and extras. Standard's pretty close to R5RS. It's getting a specification for library modules, a specification for exceptions that's less labyrinthine than r6rs's, and official requirement for allowing curly and square brackets.

Oh and some dumb fuckers thought it would be a good idea to make it case sensitive.

R7RS large hasn't been fully drafted yet and I'm not exactly sure what makes it distinct from SRFI's, but at least it keeps the C++tards on the steering community from fucking up the R7RS that matters like they did with R6RS.

assembly, c, and python

my genetic expression language specification is in need of a method of insuring sane mutation to the constants.
my intention is to have the instructions and constants seperate and to just ignore the unused constants, i have deemed the memory overhead acceptable.
so, as an example,
instructions: [8][8][8][8]
constants: [16][16][16][16]
the algorithim i use for mutating/crossing over the instructions is irrelevant, i am more worried about the constants, i don't think mutating them with the instructions will result in "pure" evolution. (imagine a program that only uses 1 constant competing with other programs that use 3, the one that uses 1's mutations might end up taking up the entire "landscape" and push the ones that use 3 out. i think, at least.)
the application that i am targetting will very heavily depend on them, with results ranging from 0% effectiveness to 87%, and the test i intend to run is going to be pretty performance intensive, so i can't easily bruteforce the constants. (and it can't easily be parallelized)
any ideas?
to clarify, the instruction set will include an instruction to acquire a constant, therefore i will require (could probably be optimized out later down the line) the same amount of constants as instructions.

Wrote C and assembly in highschool. Grew up, got jaded and lazy, been writing in Python for years. Decide to try a change and started learning Common Lisp, rewriting a bunch of tools I already made in Python in Lisp to get practice. map functions, tendency to favor recursion. it's a really beautiful clean language, i finally see what I've been missing.

As opposed to wrapping certain things in {}, other things in [], then other things in (), then some others have none of these, and some even go within arguments.

hi /dpt/, I have no programming experience but I'm trying to do something. I have a 60 page pdf with a lot of lines like this

Parish Records John Brown 142 1720-1794

where the "142" is a reference to an image

Is there a way to scan and automate the linking of these images? I'm trying to make it easier for the old lady I'm giving this to, so she can just click on the 142 in the pdf and it will open the image for her.

>>61265363
can't you make links within the file using some pdf program?

>>61265352
yeah basically. lets say you're on some ghetto rig without any sort of text editor, you could run your own buffer this way:

patrick~cat > ~/balls << EOF                                                                                             1
heredocpenis

patrick~cat ~/balls
penis

>>61265381
wouldn't that require me to manually link hundreds of images, highlighting each number and navigating to the correct picture on the hdd to hyperlink it? I was hoping there would be a simpler way in perl or something

>>61264231
Ruby, SASS and Node.JS

>>61265363
if you have access to vim or something it'd be

%s/142/<your link>/g

>>61265398
>wouldn't that require me to manually link hundreds of images
oop my bad
i'd use some pdf library to open pdf's and change them(i would use python, but perl must have these capabilities too) fiddle with the file automatically

this >>61265406 looks better, but it looks too simple and i dont fully understand why it works

>>61265390
I see, thanks anon

>>61265406
I have all the files (pdf and folders of images) on a flash drive, so I can plug it in to a windows or linux pc.
what would that line do?

>>61265426

this sort breaks it down
https://stackoverflow.com/questions/25684559/what-is-the-difference-between-g-and-s-commands-in-vim

vim is basically interactive sed.

%s is a search and replace method and g means global (aka if we are searching and replacing for a pattern do it for all of the pattern occurrences that match)

so:

:%s/stank/wank/g

replaces all instances of stank with wank. regex is a thing here too so

%s/^stank/wank/g

only replaces stank with wank where stank is the very first word on the line.

>>61265426
That is a Vim command. "s" is for search, the first term is the target, the second is the replacement, and the "g" is for global (entire document).

>>61265437
if you're trying to replace lines in lots of files you need to use find in conjunction with sed:

find . -type f -exec sed -i 's/stank/wank/g' {} +

this looks in '.' (which means current directory in linux) though any object that is a file (-type f) and runs the sed command to search and replace against it.

>>61265470
how would that be automated for a number range with all the images?

>>61265437
Replace every instance of 142 on a line with <your link>. His approach is a bad idea though because you'd have to retype a slightly different command for each file, and I'm guessing you have hundreds.

A better approach is for the first number, navigate the vim cursor to the start of the number then press

qq
i
file:///image_folder/
<esc>
ea
.jpg
<esc>
q

Then navigate to the other numbers and press @q over their first digit.

What this is doing is recording a macro that turns a number into a link.

>>61265496
sorry i forgot to include that, look at the post directly above this yours

>>61265505
your method would take forever. i doubt they want to do this interactively. My method works fine but I'll add the caveat that if files differ it can be handled with precise regex use only. find+sed still requires you to be precise in what you want

>>61264997
or

. .bash_profile

I think that's what you were trying to do, you just forgot the space.

.

(with a space after) is the same as:

source

>>61265526
It would take less time then entering a sed command for each number.

And depending on how structured the pdf is, you could modify the macro I described to jump to the next number

If it's just hundreds of that line it's just

qqi
file:///path_to_folder/<esc>
ea
.jpg<esc>
j0
/<I need to learn regex but whatever the regex for finding a number is>q

>>61265562
Well I guess if you assume that most people have one word last names then you could replace the search with just 4 W's, and correct people with weird last names.

Then repeating the macro is just 9999999999@q

>>61265551
yeah that seems to work as well

I'm totally new to programming, using "The C Programming Language (2nd ed)" to learn C; had trouble with one of the exercises the challenge is:
"Write a program to copy its input to its output, replacing each string of one of more blanks by a single blank"
using my code, inputing the EOF (ctrl + d for my machine) does nothing, when it should begin the while loop and close it when its done, what am I doing wrong? Sorry for my spaghetti code, this is really my first time writing anything that I'm not just copying.

#include <stdio.h>

int main()
{
  int c;

  c = getchar();
  while ((c = getchar()) != EOF) {
    if (c = ' ') {
      putchar(c);
      while (c = ' ')
    c = getchar();
    }

    if (c != ' ') {
      putchar(c);
    }
  }
}

>>61265782
>while (c = ' ')
This should be ==. You're getting stuck in an infinite loop here.

>>61265796
Actually, it's the same with the
>if (c = ' ') {
= assigns a value to a variable. == tests if something is equal.

So anons, is K&R second edition still relevant today even though it was published in 1988 and C11 is the new standard? Are there any other good sources to recommend that are more recent (books/online)?

Kind of curious how to work OpenGL with C too.

hello again. yesterday i posted this code here:

        # Extract needed info from JSON
        image_url = json_dict["image"]
        image_file_ext = json_dict["original_format"]
        image_height = json_dict["height"]

            # Grab the filename from the url by throwing away everything before the last forwardslash
            image_filename_crop_regex = """.+\/(.+)"""
            image_filename_search = re.search(image_filename_crop_regex, image_url, re.IGNORECASE|re.DOTALL)
            image_filename = image_filename_search.group(1)
            image_output_filename = image_filename+"."+image_file_ext
        else:
            image_output_filename = submission_id+"."+image_file_ext
        image_output_path = os.path.join(output_folder,image_output_filename)
        # Load image data
        authenticated_image_url = image_url+"?key="+settings.api_key
        logging.debug("Loading submission image. Height:"+repr(image_height)+", Width:"+repr(image_width)+", URL: "+repr(authenticated_image_url))
        image_data = get(authenticated_image_url)
        if not image_data:
            return
        # Image should always be bigger than this, if it isn't we got a bad file
        if len(image_data) < 100:
            logging.error("Image data was too small! "+repr(image_data))
            continue
        # Save image
        save_file(image_output_path, image_data, True)

and asked why the program treats ".png.svg" as png file. so i actually decided to modify the code a bit but...i couldn't even add a single print() properly. i don't fucking get this python syntax, denting etc at all
could someone, PLEASE, modify this code according to the instructions in the picture so it won't annoy me with denting or compile a program that crashes on startup?

I can't recommend any C books other than Deep C Secrets which is an intermediate C book.
>OpenGL with C
OpenGL Superbible is what you want. The book is technically C++, but OpenGL is so thoroughly a C library that the only C++ stuff that sneaks its way in is the window creation code, and you can just use SDL rather than whatever the book uses.

OpenGL 1 is completely deprecated and slow. OpenGL versions > 3 don't work at all with OpenGL 1 calls. It's an utter waste of time to learn any OpenGL 1. If you see a book or tutorial that mentions glBegin(GL_TRIANGLES) drop it.

Hey I posted >>61265782 earlier
I just started K&R 2nd ed and I'm sure its fine. There are some discrepancies, but nothing that wont compile. GCC gives me warnings on them (like needing a "return type" or whatever for the main function; main(){} becomes int main(){}) and while I'm on the first chapter still, I like to think the skills I learn from this book will still be applicable today and that I can learn the new parts of C while using it. I got mine used for around 15CAD so it's only really an investment in time, and im only doing it for fun so thats not a big deal for me.

wait, wait, wait. the spacing is critical here
if i write the if along the line of other ifs, N++ groups it as a part of the line above, as seen in the top picture, and compiler cries about denting. moving it further to the left gropus it as separate thing and program compiles but it crashes the moment it starts running

Because its a trivial algorithm to implement that also serves as a good indicator of performance and language capabilities?

That's the beauty of shell. Here is the same function but verbose (identical performance-wise):

        declare -i sum i j
        [[ $1 -ge 2 ]] && sum=2 || exit
        for ((i=0; i<=$1; i++))

        do
                if [[ ${x[i]} -eq 1 ]]
                then
                        sum+=i
                        for ((j=$((i * i)); j<=$1; j+=i))
                        do
                                x[j]=0

}

>Writing a fast sieve of Eratosthenes gonna need
Yes, but in terms of regular languages, it's still pretty slow. The same algorithm implementation in Python is ~300ms to sum the primes under 2 million, so huge difference.

 16 bool nums[NUM];
 15 int main() {
 14   int sum = 2;
 13   int i;
 12   for(i = 3; i <= (int) sqrt(NUM); i+=2) {
 11     if(!nums[i]) {
 10       sum+=i;
  9       for(int j = i; j < NUM; j+=i) {
  8         nums[j] = true;
  7       }
  6     }
  5   }
  4   for(; i < NUM; i+=2)
  3     if(!nums[i])
  2       sum+=i;
  1   printf("%i\n",sum);
  0   return 0;
  1 
  2 }
$gcc -o sieve sieve.c -O5
$ time ./sieve
142913828922

real    0m0.008s
user    0m0.004s
sys     0m0.000s

I cross checked the assembly just to make sure GCC was actually doing the algorithm, and yeah. Fucking computers.

Stop makingf un of us. You are "false flagging" and being very mean.It is not our fault we cannot use loo. We would be execute. Maybe white man should have thought of that before bringing it here. We could have invented ourselves but we have no resources, it all is belogning to superior caste. Such stupid goat animal they are. One day we rise against them and India will be come much greatter nation. We are the one who is with intelligence to code. We are capable, disciplined. They just dont know about anything and they are trying to just use their stupid "eye phones" and fart on stupid toilets. They are not our friend. They are needing to be dispose of. Half my family die because these "Indian" "peoples" are greedy. Pelase understand I really just want to hurt them so much.

>>61268261
I changed j+=i to j+=2*i and now it's just so fucking fast.

Fuck.

Also anyone know the resolution of time? I just noticed user + sys is extremely inaccurate and I no longer trust the readings I'm getting.

Or a way to measure in nanoseconds? I might just make my own timer that uses the monotonic clock.

>>61268396
For what purpose? Sepples code that makes sepples code look readable is much better.

>>61268373
Yuck I forgot common had 2 namespaces. Disgusting.
>lisp-autist-p
Are ?'s and /'s really not allowed in common? So you common lisp weenies can't do:

(define -pi/2 (* -0.5 (acos -1)))

>>61268428
Not him but:
>(define -pi/2
Disgusting.

>>61268428
They are allowed, but I like p for predicates more than ?

>>61268440
It's a beautifully concise human readable constant.

Would you rather it be named "negativehalfpi" or something?

>>61268356
Fuck I forgot, sorry.
Still haven't learned why dependent types are needed.

>>61268428
It's allowed.

>>61268453
No, I would rather it be named (- (/ PI 2))

>>61268428
>needing a constant like that

>>61268394

>I cross checked the assembly just to make sure GCC was actually doing the algorithm
The compiler will evaluate during compilation? And you're certain that it didn't in this case? Because timing the compilation, it takes ~100ms, which seems like a lot for this small amount of code, but I have no experience nor understand with compilers.
Also, 1) NUM is actually 20 million in your code, not 2 million, yet your sum is for 2 millio, and 2) your algorithm returns the wrong answer (it doesn't work) compiled on my machine.

I've just been sitting staring at my code for three hours. How the fuck do I get myself to actually do work?

>>61268569
Yeah compilers can evaluate during compilation. That's why doing i < sqrt(NUM) for a predicate isn't a performance hit.
You can read the source code with

gcc -S sieve.c -O5

Also it should be "long sum" not "int sum" and I did indeed miscount the num. I forgot to copy n my correct version. The real version does use 2000000

>>61268574
You're supposed to be a programmer, right? You should be good at designing test cases and running diagnostics.
Figure out what's crashing you.
What do you need? Are you hungry? Thirsty?
Tired? Antsy? Dirty, sick, foggy headed, sad, horny?
Then eat, drink, rest, exercise, bathe, medicate, caffeinate, contemplate, and/or masturbate, respectively.
Then come back to your work in about an hour and you'll be able to look at it with a new perspective.

WTF is wrong with you?

Probably do something else for awhile, or read through language docs and learn something new.
Sometimes i take notes on everything in my code. I find it's easier to find flaws with the logic, or
whatever, actually reading those notes aloud. This is especially after working with something for so long.
Works for me anyway.

I've already done all that and masturbated 5 times. It's likely just due to thinking about the ammount of code I have to write to get something that's barely functional.

>>61268820

Modularize senpai, break that shit up into pieces.

Most tasks have an independent function that's called when needed.

It's basically an up to 5v5 card battle RPG type game, so I need learn how to automate the battle process mostly.

>>61268574
Well, I usually break my code before leaving. And then fix it in an instant the next day. Give it time.

I'm pretty school my school is jipping me. This probably isn't the thread for this but what all should I know before I graduate? i'm like 99.9% sure despite doing all my work and self-study i'm far behind where a normal CS student from a decent school would be.

Hey /dpt/. How much does anyone know about Vector Clustering algorithms? I'm looking to design an algorithm to group elements of arbitrary vector spaces with respect to a metric. Was looking to implement it on an n-dimensional space of doubles in C then also see if I can modify it to compare arbitrary length mp3s using some convolving technique. Anyone have good reading on this type of thing?

>>61269982
should've majored in math. I did my undergrad in math+EE minor and I have never felt like CS people knew something I didn't.
