There are many ways of doing this, including looping over the lines read by 'read'. The simplest is probably awk, but here's a version with sed:

echo 192.168.1.30 | sed "s/^\(.*\)\.[0-9]\+$/\1.1-\1.255/"

I still wouldn't do this with bash.

bumoing question

if im just a neet who works by himself, is svn or git better?

So is Rust like C with some FP mixed in?

when people explain the differences between python and java why do they always mention that java is statically typed? it sounds like a much bigger deal than it actually is. it doesnt even fucking matter.

just my noob opinion

>>58690883

How do I get better at math?

Should I just go through all the math subjects on Khan Academy or will that be too basic?

I want to start doing speed math competitions so I can think faster and then start doing coding competitions.

>>58690895
>just my noob opinion
At least you know that.

>>58690977
As with all programming you should only learn what you need.
Khan is good up to and including pre-calc.
After that I would use textbooks.
Textbooks offer more in depth demonstration and proofs which are necessary for conceptualization and conceptualization is necessary for application.
You don't really need calculus unless you expect physics problems.

>>58690580
Found an alternative using arrays:

file=list.txt
IFS='.'
while read -r aaa bbb ccc ddd
do
printf "%s" $aaa
printf "."
printf "%s" $bbb
printf "."
printf "%s" $ccc
printf ".1-"
printf "%s" $aaa
printf "."
printf "%s" $bbb
printf "."
printf "%s" $ccc
printf ".255"
printf "\n"
done < "$file"
read

It just werks.

>>58691249
Please don't do that. Literally copy and paste this code into your terminal:

cat MY_FILENAME_HERE | sed "s/^\(.*\)\.[0-9]\+\$/\1.1-\1.255/"

17KB, 659x469px

The issue is resolved, but now I'm trying to use arrays just for the sake of it and found a problem:

file=list.txt
IFS='.'
while read -r a b c d
array=("$a" "$b" "$c" "$d")
do
printf ${array[0]}
printf "."
printf ${array[1]}
printf "."
printf ${array[2]}
printf ".1-"
printf ${array[0]}
printf "."
printf ${array[1]}
printf "."
printf ${array[2]}
printf ".255"
printf "\n"
done < "$file"
read

It works in the beginning but when the list ends it just loops forever (pic related). How comes?

>>58690557
How about this - https://github.com/Reactive-Extensions/RxJS

#include <iostream>

class fizzbuzz {

public:
  fizzbuzz ();
  fizzbuzz (const fizzbuzz &other);
  fizzbuzz &operator = (const fizzbuzz &other);

private:
  int _value;

};

inline fizzbuzz::fizzbuzz () : _value (0) {}

inline fizzbuzz::fizzbuzz (const fizzbuzz &other) {
  _value = other._value + 1;
}

inline  fizzbuzz & fizzbuzz::operator = (const fizzbuzz &other) {
  _value = other._value;
  if (_value % 15 == 0) {
    std::cout << "fizzbuzz";
  } else if (_value % 5 == 0) {
    std::cout << "buzz";
  } else if (_value % 3 == 0) {
    std::cout << "fizz";
  } else {
    std::cout << _value;
  }
  std::cout << std::endl;
  return *this;
}


int main () {
  fizzbuzz fb;
  for (int i (0); i < 100; i++) {
    fb = fizzbuzz (fb);
  }
  return 0;
}

Beware, that code is incorrect.

>>58691667 (cont)
It's still looping but I made a small revision here:

file=list.txt
IFS='.'
while read -r a b c d
array=("$a" "$b" "$c")
do
printf "%s." "${array[@]}"
printf "1-"
printf "%s." "${array[@]}" 
printf "255"
printf "\n"
done < "$file"
read

Any ideas what's causing the loop?

what's the most anime language?

>>58691876
The most cancerous language? C++.

Any good sites to learn web/software development independently from? I'm trying to get back into programming after putting it aside because of muh studies which was kind of a stupid decision.

I've farted about with C++ and Lua before stopping, but I'm looking for more structured learning. I'm sure I have to pick up C/C++, HTML, CSS etc.

No bully pls

>>58691876
Common Lisp and C

@58691914
hello rddit

>>58691483
No worries. Here are the two best resources for bash scripting that I've found:

http://tldp.org/LDP/abs/html/
http://mywiki.wooledge.org/BashGuide

I would warn you not to attempt too much in shell; I find it to be unreliable and generally quite risky.

>>58691914
This post is hate speech.

>>58691944
I dunno, I just read books.
Also, check /wdg/, it has resouces about web development.

>>58691856
Try it without using the 'read' on the very last line.

To be honest, I would avoid using arrays in bash. They are messy and dangerous. If you need aggregate data types, you should probably switch to a full-blown programming language.

>>58691987
>I would avoid using arrays in bash
Indeed, it's still broken even after removing read, I was just playing around with what I learned anyway, what I needed the most was accomplished with the sed script from before.
I'm planning on learning more Perl since I made some stuff in the past with it, so it's the most familiar language for me at the moment.

>>58692045
Well i currently just 7zip the dir and stick on another drive & a flashdrive. But i feel like i should learn """proper""" src control

>>58691667
What are you doing? It could be made a hell of a lot easier probably.

You can loop over lines in a file by using

for l in $(cat $filename); do
   #shit
done

And for the print formatting you should be using sed (use group capture).

I am on exercise 1-20 on K&R C, but I literally have no idea what I am supposed to do. I thought I was just supposed to replace tabs with spaces equal to tablength, so I just used the standard tablength of 8, and wrote this:

 #include <stdio.h>

#define TABLENGTH 6

main(){
    int c, i;

    while((c = getchar()) != EOF){
        if(c == '\t'){
            for(i = 0; i<TABLENGTH; ++i)
                putchar(' ');
        }
        else
            putchar(c);
    }
}

This worked for what I wanted to do, but then I looked up the solution and I found this shit: http://www.learntosolveit.com/cprogramming/Ex_1.20_detab.html
and I am almost certain I did some shit wrong/didn't understand the problem. I don't understand what is going on in the solution at all, can anyone help?

>>58692098
>But i feel like i should learn
no you really shouldn't

>>58692155
>What are you doing?
I've a list of IP addresses and I'm converting it to ranges, like:
>192.168.1.69 (b4)
>192.168.1.1-192.168.1.255 (after)

Like you mentioned there's a way with sec, which anon posted here: >>58691277 but I still wanted to try using an array, though looks like bash is kinda slippery with this.

>>58692224
>sec
sed*

>>58692204
Do you not know how tabs work? They align text on the next column that is a multiple of 8. You can't just turn a tab into 8 spaces.

>>58692224
I would expand on my earlier post by saying that any time you need string processing beyond a sed one-liner, you should again use a full-blown programming language.

While I've done a lot of shell scripting in the past, I've come to regard shell languages with fear and suspicion. Often, the few extra characters you have to type if using Python, Perl or Ruby are well worth it in reliability and, honestly, sanity.

>>58690487
I want to learn code but I have to chose between JS, Java and swift.
What does /dpt/ recommend?

>>58692204
The \t character is variable length. It pads the string to the multiple of where the tab would go. You have to keep track of the characters read in and pad TABLENGTH-chars_read_in

>>58692292
As a first? Java. Cross-plat and not JS (shit). Make sure you learn Java 8 patterns after you learn the basics.

The programming community should collectively refuse to use JavaScript, to force better working conditions from employers.

>>58690860
https://git-scm.com/book/en/v2

>>58692262

Also here's how I would do it with a while loop:

while read -r ip; do
    echo ${ip%.*}.1-${ip%.*}.255
done < "$MY_FILENAME_HERE"

However, this will only work in some shells (tested in bash), whereas the sed version only requires that you have the right type of sed installed.

>>58692303
>patterns
You could just use a not-shit language that doesn't need 'patterns'

>>58692329
>The programming community should collectively refuse to use JavaScript, to force better working conditions from employers.

>>58692262

Those are all shit languages and you should feel bad for using them.

>>58692341
In fact, I've just noticed that those string substitutions are pure bashisms, so I really wouldn't expect this snippet to work in anything but bash.

>>58692050

>>58692342
"patterns" is a generic term you retard. I mean learn the functional-esque shit they added, not just the bog-standard procedural/OOP stuff.

>>58692357
>Those are all shit languages
Yeah, well, that's just, like, your opinion, man.
>and you should feel bad for using them.
I don't use them.

I'm not a good bet for this kind of shitposting, have a go with someone else.

>>58692377
They're objectively shit, they retard development and have poor performance, there's literally no reason to ever use them.

>>58692389
Scripting languages aren't indented to have C-like performance and they have their niches, which don't require hard real-time responce.

what's the best way to pick a pivot for sorts?

>>58692410
That was me. I also alluded to the while loop solution here: >>58690565

I generally do not use awk because jumping from shell (a DSL with problems) to awk (another DSL with problems) is avoiding the issue. The sensible solution is to switch to a general programming language.

>>58692419

>>58692470
Lua and Julia are possible solutions. I'd also make a case for Common Lisp.

Forth is probably not 'easy for retards to use' due to being concatenative.

Converting an IP list to ranges.
There're 3 working solutions at this moment.
Using sed:

cat MY_FILENAME_HERE | sed "s/^\(.*\)\.[0-9]\+\$/\1.1-\1.255/"

Only bash:

while read -r ip; do
    echo ${ip%.*}.1-${ip%.*}.255
done < "$MY_FILENAME_HERE"

And my shitty bash without sed:

file=list.txt
IFS='.'
while read -r a b c d
do
printf "%s" $a
printf "."
printf "%s" $b
printf "."
printf "%s" $c
printf ".1-"
printf "%s" $a
printf "."
printf "%s" $b
printf "."
printf "%s" $c
printf ".255"
printf "\n"
done < "$file"
read

They all work, except mine is bloat.
I tried to redo with an array, which failed (causes a loop):

file=list.txt
IFS='.'
while read -r a b c d
array=("$a" "$b" "$c")
do
printf "%s." "${array[@]}"
printf "1-"
printf "%s." "${array[@]}" 
printf "255"
printf "\n"
done < "$file"
read

>learning C

>>58692504
>going to a school where you weren't just expected to know C already
topmost kek

>>58692513
Actually, yours isn't necessarily bloat, since you can convert all those 'printf's into one 'printf' (or 'echo'). The reason I wouldn't recommend doing it is just that you messing with the IFS.

do
echo $a"."$b"."$c".1-"$a"."$b"."$c".255"
done < "$file"

what is the point of programming anymore unless you're doing it as a hobby?

I stopped being a sperg for once and got an objective view of the software industry. Software no longer makes any revenue through selling licenses. Open source software is rapidly replacing paid software.. SaaS, Full Stack start ups, and crowdfunding projects is really the only way to make money with software nowadays. There is also artificial intelligence coming sooner than expected within 10 - 20 years, once that happens programmers are all fucked. The way i see it a career change is the only option out of this.

I'm working on a console interface for BasicTV. I have the following down
1. Commands that output usable information will put it in a table (output_table)
2. IDs will be read from this output_table, in human readable format (hex), into the registers (IDs only, binary format)
3. You can skip around in linked lists and perform some general purpose memory management: export to disk, delete, see all data, modify IDs it references. Most of the stuff is too technical to be useful to most people.

The only way to interface with the console is to use telnet. There's far too much debugging output to use the terminal, and connecting over the Internet is pretty cool (of course, with a more secure protocol). This console is the only way to upload content to the network, but that should be pretty easy to do.

This also controls which channels you are watching, the layout of the screen, controlling the TV Guide (not implemented yet), and doing pretty much everything a remote would do.

It doesn't go into a loop; the 'read' on the last line causes it to watch for console input (i.e., for you to hit return). If you remove that, it works on my machine.

This was tested and confirmed to work in bash:

IFS='.'
while read -r a b c d; do
    printf "%s.%s.%s.1-%s.%s.%s.255\n" $a $b $c $a $b $c
done < "input.txt"

Where 'input.txt' is a plaintext list of newline-separated IP addresses.

Also, as discussed, you could also use echo, i.e.:

IFS='.'
while read -r a b c d; do
    echo "$a.$b.$c.1-$a.$b.$c.255"
done < "input.txt"

Finally, the (very important) thing that I forgot to mention: IP ranges start at zero, so your output should really be:

192.168.1.0-192.168.1.255

Fixing this in the examples posted is straightforward.

>>58693126
The point is that most languages make a trade-off between performance and ease of writing correct code. For example, C leans heavily toward the former, Haskell leans toward the latter, and Java and C# are both closer to the middle.

Python chooses neither.

Does /dpt/ have infographics on good books to learn certains langages, frameworks, etc, ... ?

>>58693164
In terms of speed, Haskell can match and even surpass C.

>>58693164
Yes, Haskell can be quite fast, but it usually involves considerably more effort than that needed to just make it correct. Making Java code performant is usually more straightforward (but making the code correct in the first place is harder).

>>58693202
Yeah, only Haskell can create that much garbage/second.

Gotta invalidate fast.

>>58693212
Yeah, you essentially have to write C in Haskell, which isn't nice.

That said, like any language, you get a huge amount of mileage out of making sure your algorithm is optimal and then changing to 'faster' datatypes, the latter of which is particularly pleasant in Haskell.

Could it be related to MinGW then? I tried without read already but it didn't fix it.

- Learn C# .NET
- Be better at making websites (Other than using Bootstrap, I didn't do much)
- Javascript

I also need some methodology advices on how to learn a langage, I really didn't learn much at school to be honest besides making some websites or application for companies that needs to sell things.

It's hard to answer such a general question, but the critical thing is to keep writing programs. I suspect that other than a few hand-holdy exercises, you don't actually have to do much programming in most university courses.

You should try reading the answer rather than the question :)

I trust you guys implicitly.

you're objectively wrong. the questioner's implementations were suboptimal, and even the optimized haskell was only within the margin of error compared to the questioner's C code. with a better C implementation, it's much faster than the best haskell implementation. you're not fooling anyone but yourself.

Ever thought about taking that VM down to the hardware level? Download Vivado, learn some VHDL, remake the VM as an actual machine. Maybe if you save up $1000 you can buy an FPGA board and test it. Or even build it using a bunch of ICs.
