>>58309082
What are the defining features of that data structure?

>>58309114
It's a tree of a certain element type, except each level you go down in the tree it becomes a list of the previous element type.

E.g. root node is a T, its children are vector<T>, their children are vector<vector<T>>, etc

I'm working on my image viewer, Ivy. I now have this window that you can open that has all the errors that may have occurred. Took me a little while to figure out how to get the (current-error-port) to write all its information to the error log window - what I ended up doing was saving the old error port, creating a custom output-port that writes both to the old error port and to the error log window, then set that as the new (current-error-port). This way, any errors will appear in both the window and on the command line.

>>58309648

Thinking about making something like ncurses from scratch.

I found out about blessed for node.js and it's pretty cool, aside from the fact the code is ugly as fuck, the widgets it can make are nice.

I already wrote a terminfo parser and library, now I just need to figure out a good API that's ergonomic enough to use and to create additional widgets.

>>58310308
Every library that doesn't have a C ABI is complete garbage.
You're basically making your library far, far less useful and are tying it to your shitty meme languages for no reason.

>>58310286
>take care of yourself
I primarily program in C.
I don't consider C++ to be hard, I just consider it to be fucking retarded and designed extremely poorly.

>>58309082

This is trivial in any dynamically typed language. Ruby, Python, JavaScript, Lisp (and the majority of its variants), Lua, and many others can create an array/list that can store objects of different types.

In C++, I could probably generate that with some template magic and recursion, but only up to a known finite depth.

>>58310334
>ABI
API*
although you need the ABI too.

>>58310334
Having a C ABI implies making the API much less ergonomic, which I'm not interested in.

You have ncurses, it's shit, use it and enjoy yourself, I'm going to make a library I enjoy using myself.

All the software I make, I make for myself, I couldn't care less about how useful it is to other people.

>>58310374
>All the software I make, I make for myself, I couldn't care less about how useful it is to other people.
Ok, I'll give you that.
Due to the fact that you were "advertising" here, and were worried about ergonomics, it seemed like you actually wanted other people to use it.

>>58310374
ncurses is fine and you like making life hard for everybody who doesn't use a meme lang

>>58310367
>This is trivial in any dynamically typed language
But is it type safe?

>>58310396
>ncurses is fine
Not him, but ncurses has far too much global state and weird macros for my liking.

>>58310390
It's not even remotely "advertising", I didn't link to anything, I'm just doing what you do in a /dpt/, talk about what you're working on.

Obviously I'm concerned about having an ergonomic API, or I'd be using ncurses.

>>58310396
If ncurses is fine, how am I making life hard for anyone by making an alternative for me (and anyone who wishes) to use?

Jesus fucking Christ. EVERY good programming language is literally just lambda calculus plus a few features. Underselling potentially the greatest human discovery of the 20th century like this is disgusting.

Having a C ABI means that a library can be trivially ported to other languages without rewriting a lot of code.

>>58309168
I'm not a C++ user but I'm guessing that they're dynamic arrays.

https://en.wikipedia.org/wiki/Dynamic_array

TLDR a data structure like an array but when its full just makes a bigger array and copies everything over. Size grows geometrically so you have to do the copying less and less as it gets large but the trade off is wasted space.

Anyone have experience with NVidia FLEX? Documentation seems pretty sparse.

>>58309185
>not saying that vectors are firsy order tensors
spotted the academic of trivia

>>58309168

In the context of data structures (particularly those offered in C++'s Standard Template Library), a vector is a resizeable array with the ability to have an amortized O(1) appending of elements. In the worst case, append is O(n), but this only occurs every O(log(k)) times out of k appends.

In the context of mathematics, the concept of a vector can either be thought of as "something with direction and magnitude" (for instance, velocity and acceleration), or as a 1xN matrix, depending upon which area in mathematics you are working with.

The term "vector" is used for way too many things.

>>58311113
And I found the guy who doesn't know what a tensor is!

I wanted to use the function

char *strchr(const char *str, int c)

to count all a e i o u y in a char array but this shit is not working. does anyone know why? somehow the if statement is always true and it counts to 999

>The C library function char *strchr(const char *str, int c) searches for the first occurrence of the character c (an unsigned char) in the string pointed to by the argument str.

my program works with a switch statement instead of strchr.

#include <stdio.h>

int main(void) {

char array[1000] = {0};


int N;
printf("how many lines?\n");
scanf("%d ", &N);

int i;
int i2;
int counter[1000] = {0};

for(i2=0; i2<N; i2++) {

memset(&array[0], 0, sizeof(array));
fgets(array, 1000, stdin);


for(i=0; i<1000; i++) {


if (strchr("aeiouy", array[i]) != NULL) {

        counter[i2] = counter[i2] + 1;

}

}

}


for(i=0;i<N;i++){

    printf("%d ", counter[i]);
}

return(0);
}

>>58311139
Basically the vector can act as a body of transfer.

In your typical program, the processor reaches for data wherever it may be. Although the same is true for all programs, the design of a vector, besides the necessitated use of it for quickly modifying arrays, stems from it's ability to act as a modicum of intent and magnitude within the fily system.

Have you ever played the snake game? That snake is a vector, and it grows by 1 every time it eats a block. A vector can be imagine to be that snake moving around the filesystem or ram state ( in a pointer language, of course ) and either supplying info or appending its list with more info.

Vector is popular at the low levels of computer programming because it heads the baseline of performance by automating arrays operations and integrating with the primitive of values. It can also represent or gauge more using the attributed properties of any particular vector and/or data construct the way those block visualizers gauge the signal at any particular frequency.

As a programmer, which CoC do you prefer?

>>58311320
None, see D

>>58311301
Not to be confused with a body of transfer. It's a body for transfer. So, while it could represent a physical thing that can hold and contain or whatever, it's really just relegating the sense of inhabitance and "fullness" to the purpose of the data. As long as there are elements in the list, the program has a purpose.

>>58311243
What a mess.

1. indent your [ code ]
2. strchr() and memset() are functions of string.h, you should include it
3. reread the specification of strchr(). This is not what you want, what you're looking for is strpbrk().
4. &array[0] == array
5. the inputted line may well be bigger than 1000-1 characters. As an exercise after this one, learn how to resize a C string dynamically and fill it with a fixed size buffer as long as the line has not ended.

Is it possible to open up a disassembly (x86 instruction set) of a certain program and start the execution at one of its subroutines, and only execute that subroutine along with the subroutines it calls, if all it takes is one register as an argument?

I think it should be possible, but the disassemblers/debuggers I've tried out (IDA and Ollydbg) only seem to allow full execution, and I can't execute the whole thing. I'm obviously new at this.

If variables are left undefined they have an undefined value.

>>58311608
Yeah, it's possible with a debugger, but you need a core dump of program state at the moment the program just called the subroutine in order to do it easily.

Otherwise, you could reassemble a program including the subroutine and its callees, and calling the subroutine from main, eventually with some initialization before.

You model strategies around fractals.
"You do thing and then...you achieve thing and then you...you commit thing and then..." so on and so forth. I'm not so good at metaphors or analogies for fractals, probably because they act as such. I wish I could provide more insight.

I haven't posted my own code on github as of yet, but it's very similar to the sample the creator has in the library's own page.

https://github.com/xerpi/sftdlib

I think it might be either how I compiled the files, or the order in which I listed all the lib.a files in the Makefile. But I figured if that was the case, then it wouldn't have loaded at all.

It has me pretty confused.

if\n then \n else\n fi
set with n=15 or n=$(ls), recall with $n
wrap math in (())
if you need anything more complex than that+stringing together tasks in a row, a) don't use bash for it, and b) studying bash scripting won't help

A good reason to use Haskell for projects is that you won't ever hire and subsequently have to maintain code written by Java or Python or Go or JS programmers.

You need to understand that there is a lot of pedancy here. Not just becaue asians and autist white kids, but because black "intellectuals" and the general fedora, as well.

When a topic shifts from code to correction, is usually a good idea to ignore that MOD, yes it's a mod, and look for someone else to talk to.

Remember, autist, asian kid, black man, fedora.

You're either going to be arguing with the autist's mother, the asian kid's whole country and legacy, black man's hood/mother/woman/enemy/church/favorite superstar/pains/current insecurity/favorite twitter personalities/favorite youtube personalities/favorite rapper/etc. ALL AT ONCE ( that's why it's like you're always arguing with the same person over the same stupid shit ), and the fedora's unwillingness to confide in another's intellect. Mostly due to the above and the general nature of the normie way versus what it's like on the internet and in books.

By adding ever more protected classes to a project's code of conduct?

I think I get it.

>>58313622
feminist women figured out that "coding" actually requires lots of effort to become competent and they took the easy way out

they can insert themselves into software projects by demanding that projects adopt condescending "code of conducts" to "protect marginalized people" from the grown men who work on that project.

The "coders covenant" encourages expulsion from a project for committing wrongthink on a public forum that has nothing to do with the project.
Basically, it's an insidious way to remove people who oppose feminists.

eg, a developer for a project says something politically incorrect on twitter and apparently the project is supposed to expel this developer no matter how valuable he is, despite the tweet having nothing to do with the project.

>>58313696
>Don't you look for common constructs?
Yes, but I didn't see any. Just a bunch of impure imperative stuff.

>>58313708

So how do these covenants get around ban evaders? You make a new github account under a different name and keep contributing as normal. They have no way of verifying that newcomers to the project were not a person who was previously banned.

Why not try the official one

https://www.gnu.org/software/bash/

most often, these will have the most succinct form of transcription for any process. Though, with the GNU and enterprise projects, you will probably need a bit of theory from like a programming language or at least the theory of one such language. You could do it the Computer Information Systems way but you might get lost when you get to the actual scripting over getting to know the environment.

After that, the best way to learn these things is to have something in mind and executing using the tools. One such simple activity would be setting up your linux or figuring out how to manage files in a filesystem. Things like copying individual files, reading output of file contents and then packing those in directories and, essentially, setting up a new environment for different kinds of work. Remember, everything is a file. Some of them just fit better at different points and some of them don't have enough info or have too much info when attempting to complete a task with that file. That's a general way to put it.

>>58313772

How many threads is too many? I hear people complaining all the time about applications not using all of their cores properly.

If I have a function that performs an operation on every index of a short array, would it make more sense to run each operation on each index in its own thread? Obviously there's an overhead to creating threads, so what is a sensible metric for the trade-off involved?

By itself they are quite useless, but since in most implementations you also have higher order functions and closures, you can use them to generate code or to specialize functions.

One thread per logical core. Kick them all off when the program starts (or maybe lazily) and leave them running. Put them to work using a job system.

Setting up your linux basically means filling in your /usr/local/bin directory and /bin directories with the kinds of programs you want/need. Setting paths to aliases and creating variables you think you'll be needing, in the case that you want to treat the OS like an environment rather than a simple computer.

GNU/Linux is essentially a collection of the machinations of your processor as instructions that point it at the different parts on your computer. So, like, if a directory represented your Linux Distro, one directory up would be the GNU toolset, and every directory below Linux would be describing each "machination" ( my word for concept of mechanical doohickey ) and have "driver" files that in them would refer to the machination files so that when you accessed the file from a neutral point of process, you could, essentially, "copy paste" what's on one side of the file system to another without having to describe the path of the electrical charge with an even more complicated system of inference ( Though, most tecnically, you are describing the path..just from a few orders of magnitude lower ).

So, if you want a linux that accesses things based on timing, you set up a series of folders that'll hold your timing info, start from on directory, write middle path logs to a second directory and output to a third. Then run the whole program in full and check the times.

To do the above, you would just need to set up a directory to hold those three sub-directories and from within that directory run commands that'll produce meaningful data, evaluate the processing power, time, cycles, etc. and have them output to the sub-directories.


Another thing you could do is make it run to a design if you understand your hardware real well. But that's a bit more involved and might require tinkering with the kernel.

You could set up some partition on it to act like a webserve and test out your networking skills.

>>58314137

You could set up a set of directories that hold m amount of files over n number of rows and have pixel data in each file that would output the screen the data, whether through gtk, opengl or simple ANSI styled monospace text is up to you and then use your terminal to develop a sort of game and make an environment that ignores the whole computer side of things, once you're in this directory, and just acts like a console/game debugging deal.

There's really a lot you could do with it, but you gotta be real specific or you might lose some detail or vision while trying to re-encapsulate the essence of the idea into parts that the machine can manage. It can manage a lot but the more there is to manage to more complicated it can all get. Unless you set yourself up in a way you know you can always remember and handle or if you organize yourself extremely meticulously.

So, to answer the original question:
Managing a file system is just like organizing your binder, or your windows directories, or your picture folder, or your homework folder. Just on a larger scale. There's also the idea that you want environments within the file system and that you can literally edit out anything and redefine what a filesystem is for some. GNU and Linux are not monolithic. Not too monolithic, anyway.

Is cracking the coding interview worth it?

>>58314192
and, btw, when I mean specific, I mean for the sake of having a full set of data to work off of in improving or catching mistakes from different perspectives.

Like, you could make a game that has literally 7 states and based on some really linear conditions, meaning someone chose 4 and another someone chose 2 and is next, you could prepare the next event to always be return 7 but that would be kind of unintuitive just as this example is. While the point of programming and computers is to do things quicker, marginalizing the method can lead to bogs in the future and the further forced approximation of some of the more descript things. Nothing really comes to mind right now ( ahaha ) but I know it's true because I've run into it a lot. I do recall that it would've required the same codebase for every different player to be repeated and doubly for updates. It basically cuts down on variation. I try not to mess with things of a narrowing nature unless it's from deducation. I also don't know how to just sit there and make lists without having a friend to chat to or music I can ignore ( nu jazz is good for this and I'm not even weeb or fedora )

Also, you encounter a lot more asian stuff ( don't kill me asians, I grew up with a ton of you) in working with computers and there are a lot of very forceful asian religions and ideals, vocations, parametrics, rhetoric and general shillery that I try my hardest not to have influencing me during the brainstorming, verification and validation points because those guys do not live in an environemnt like mine. I am libre and they are monolithic. Every must fit the Way. I know sometimes it's for a good reason but most of the asian dudes here are rich and don't need that shit. They'll never argue good structure and coding practice with you. They will just correct you, see re-direct, and call you poor and bytfo.

Sorry for going off topic. This place gets my dander up bui there's really no where else that offers the freedoms we get here. I don't have to click here, ask this way or that way, I can call you a fag, I can hate women, etc.

Anyway, narrowing is a both a good thing and a bad thing in programming. Good because it means you're done. Bad, in the case of not being done, because it means you have to stack it all up again and hope you don't forget the stack you had before and also maybe the original narrowing could follow a the ideal strategy whereas the second one will have to abide a whole separate strategy and thus tank performance. With numbers, you write out less, faster, and you get to say less, faster and safer.

Don't mind legibility unless you will be looking for people to read it and making sure they read it whole and give you critiques. I had a great system for myself, I could work for days, until I started trying to share my code in more ways than C. Now, I have picked up a lot more considerations and work a million times slower because of how agitated I became in deciding that these stupid faggots are the only people that will wanting to read my code.

Except ruby and a few others here. Though, the others are usually anon.

If you didn't learn English as a first language, treat it like translations and direct translations. Now explain that to an autist with aspergers and that knows how to script in bash.

Wrong.

>>58314844
Also wrong.

>>58314774
That's the problem.

Emacs is an operating system that also happens to edit text.

emacs or vim
Linux doesn't really have its own Visual Studio, you can check out codeblocks or IntelliJ though if you really need an IDE

Type theory is thankfully moving away from proof automation and tactics bullshit towards focusing on making proofs easier to write.

Working my way through pythoncrashcourse projects pretty fun book would recommend

My fucking god. My sides have passed the oort cloud.

This shit is 100% true.
I was in this exact position, and just ended up using jQuery and some lambdas. Sorry. Callbacks. It's not that hard to write

var downloadComplete = function ...

And just supply that as the callback function.
That's not spaghetti. That's not hell. That's just... A simple solution to a small problem.

>>58314838
what kind of stack doesnt make sense to you?

>>58315125
>>58315142
And by easier to write I mean having e.g. quotient inductive types built in to the language instead of setoid diarrhea everywhere. HoTT is literally that but higher inductive instead of quotient and groupoid instead of setoid.

>>58315169
It's not that any given stack does or doesn't make sense, it's that JS now has more scaffolding bullshit than Java. Except with Java, if you want full on enterprise Spring, you have ONE dependency that you declare, and tools take care of shit for you. And these tools don't change every year.

How do I train my left pinky for professional use of emacs?

I'm reading Programming from the Ground Up (http://gnu.mirrors.pair.com/savannah/savannah//pgubook/ProgrammingGroundUp-1-0-booksize.pdf) to try to learn some of the main lingo for programming while also learning some core ideas.

I have some background in C++ and Java. Is this the 'right' next step?

hopefully one that doesnt use some age-old "mailing list" shit.

C/C++

>>58315274
It's a meme since some high-profile Emacsers has it. But you can get around it by doing some simple steps. Mapping Caps-Lock to Ctrl helps a lot.

You could also try using your wrist to hit the ctrl-key instead of using your pinkey. Some people prefer that. I prefer remapping Caps-Lock because it makes other programs comfier too.

>>58315292

why dont you just go on github

i'm a total noob and I know this

>>58315403
because if i go on the "explore" tab on github I'm just going to get some fucker's repo programmed in "Go" or some javascript fuckery and all the C++ stuff actually featured is big-time shit like FFMPEG or whatever.

new to programming..i've made a few things on github and recently some people have been submitting merge requests to me after they change a few comments and nothing else

is this normal? whats the reasoning for even doing this? all they do is make my comments more wordy

Monads are a fucking farce.

If you base a language on the lambda calculus with continuations (which is more fundamental than pure lambda calculus), they're unnecessary.

>inb4 Haskellfags trying to defend a language based on a deprecated calculus

>>58315853
>impure more fundamental than pure lc
amusing but i'll humour you

>monads are a farce
Monads provide two main things
1) As they are a functor, namely an applicative, you can embed a value into a monadic computation, e.g. IO Int, rather than just a singular IO type
2) Monads allow you to make decisions on what 'effect' to do next.
Regular applicatives cannot do this.

>>58315853
>>58315967
If you didn't want embedded values, then a simple monoid (or semigroup if there's no noop) will do, e.g. raw ASM

There are other useful objects like indexed monads, which allow you to enforce certain constraints, e.g. "you can't leak file handles if you want to turn this File i j () into an IO ()"


But of course, monads work a lot like continuations.
Did >>= (\x -> ... ) not tip you off?
Do notation (which Haskell uses for monads) is actually good for continuations (which is why it works with monads).
