# New & Revised /dpt/ Code of Conduct #
We want to ensure that the /dpt/ community, while large and diverse, remains
welcoming and respectful to all participants. To that end, we have a few
ground rules that we ask people to adhere to.
- *Be friendly and patient.*
- *Be welcoming.* We strive to be a community that welcomes and supports
people of all backgrounds and identities. This includes, but is not limited
to members of any race, ethnicity, culture, national origin, colour,
immigration status, social and economic class, educational level, sex,
sexual orientation, gender identity and expression, age, size, family
status, political belief, religion, and mental and physical ability.
- *Be respectful.* Not all of us will agree all the time, but disagreement
is no excuse for poor behavior and poor manners. We might all experience
some frustration now and then, but we cannot allow that frustration to turn
into a personal attack. It’s important to remember that a community where
people feel uncomfortable or threatened is not a productive one. Members of
the /dpt/ community should be respectful when dealing with other members as
well as with people outside the /dpt/ community.
- *When we disagree, try to understand why.* Disagreements, both social and
technical, happen all the time and /dpt/ is no exception. It is important
that we resolve disagreements and differing views constructively. Remember
that we’re different. The strength of /dpt/ comes from its varied community,
people from a wide range of backgrounds. Different people have different
perspectives on issues. Being unable to understand why someone holds a
viewpoint doesn’t mean that they’re wrong. Don’t forget that it is human to
err and blaming each other doesn’t get us anywhere. Instead, focus on
helping to resolve issues and learning from mistakes.

I'm finally motivated enough to start working on my own project.
I want to create a generic front end for torrent clients so I can manage my torrents and downloads anywhere. It'll be a website so I don't have to create a client for Android and desktop. Don't worry, it's just plain HTML/CSS. It won't be a shitty web app. This is the featureset for version 0.1:
- List downloads (name, status (incomplete/complete))
- Stream download
- Remove download
- List torrents (name)
- Add torrent
- Remove torrent
Some other features I'll eventually implement:
- Feeds
- Grouping of downloads
I'll be using Go because it's the perfect language for projects like this. To guarantee the users freedom, I'll license it under the AGPL v3.

Ah, you're in that rebellious phase, it's alright we all grow out of it.
Ask your much beloved programming literate anything (IAMA).
>>54424686
System calls on Windows are abstracted by a set of procedures. Because of this, Microsoft can rearrange the system calls implementation for free. It's actually a good decision.

No idea, you could test out yourself.
I wouldn't really rely on it until MS releases their own official documentation on syscalls.
>>54424739
>>54424825
Also, if you click "show" on those columns, you can see that each windows version and service pack have varying syscall numbers for each syscall.
I would not rely on it, especially since it's unportable as fuck.
I'd stick with winapi.

Anyone know java?
I'm working with sockets and have a server set up and a client that can talk to it.
The server runs, then the client connects to it. The client is player 1 and makes a move. This move is sent to the server, and the server is able to see where the client (p1) has moved. Client (p2) is now able to make their move. Player 2 makes a move, and this move is sent back with an echo.
So in short, player 1 makes a move, and this data is sent to the server. Server is now able to make their move, and when they do, the data is sent through the reply, or "echo".
My problem is occurring when player 1 receives the reply from the server.
I have a boolean variable called myTurn that only allows you to move if it is true. After you make your turn, it is forced to false and you must wait for it to be changed to true in order to make another move.while(i.myTurn == true)
{
i.clickSet();
i.setTurn();
set(i.getBoard());
}
if(i.myTurn == false)
{
out.println(get());
boardStr = in.readLine();
set(i.getBoard());
i.boardToInt(boardStr);
System.out.println(boardStr);
}
else
{
}
You see that if it's player 1's turn (myTurn is true), it's ready to take their input, changes their turn status after they make their turn, and it updates the board. Now you see if it's not their turn (myTurn is false), you can assume that they've made their turn, so the updated board is sent to p2. Now this is where I get confused. I need something that will wait until it gets a reply back from the server to continue executing the next lines of code.
In my current program, p1 can make a move, p2 receives the data, and the board is updated to reflect this change. p2 is then free to make a move, but after they do, p1 receives the data, but cannot refresh the screen or have their turn.
>>54425307
A little more detail:
When dealing with sockets, the messages sent between them are of type String.
So the board is represented by integers, but is converted to a String that is then sent over to the next player after they make their turn. When the player receives the String, it goes through the method boardToInt and accepts the String and then updates their board to show what the other player did.
so it's a back and forth thing between server and client, but I need a method or something that can wait for the response of the server after it makes it's turn.
>>54425307
sorry if im not understanding but couldn't you just make a while statement that sits the client in a loop until the variable you want from the server is available. Like maybe just have it wait on a boolean change, Im p sure there's a wait method in java too.
also remove your boolean comparisons and just starting using if (x) or if (!x)

Hey, that aint my problem. Copy pasting code into a post fucks everything up. It looks just fine in eclipse.
I don't see myself as a 'programmer', always hated that words as I do not program anybody or anyone, - I augment the inspiration and imagination of the users of my app - this is my craft, this is what I do. I usually call myself more a "code artisan" - I know it sounds cheesy, a cliche almost, but that describes it best. I mostly work in Rails as it is simply and by far the most robust implementation of a full stack MVP experience.
To the beginners out there: you don't have to be a 10xer to start with coding - you don't even need an office. I am typing this from Starbucks (yeah I know, call me a "fag" etc I don't care) on my Macbook and this IS my office.

For my C++ class, our final is to program a store kiosk, the ones you see at like target and stuff.

I'm really out of options, the project is due in three days, and I need help. I hate asking, but can any of you anons help me out here? What I really need help with is how to make functions so that I can run a search array for item verification, and have that inside a case. How would I go about doing that?

When people come to me and ask me what to read, do you think I send them to some boring CS book?
No, I tell them: read this Autobiography written by Picasso. Go to a modern art exhibition. Learn yoga or tai chi.
Expand your mind first... the technical stuff comes later, and is quite trivial. Everyone can do a for loop, but can everyone reinvent? To become a visionary like Steve Jobs or Elon Musk you need more than technical knowledge. And code is ALL about vision.

So i'm at the point where I'm okay with using Python and Java and if i dont know how to do something I can quite easily find the answer on google. I never made a project with more than 100 lines though. Now i want to get serious and make something big. The problem is I don't know what and if Java and Python are actually good for bigger projects. I would be fine with learning a new language as I'm a pretty quick learner. Any concers/help?
>>54426069
Java isn't really used anymore. It's only there for legacy purposes and Android. Python is fine though.
>>54426069
Step one is find something you want to do.
Step two is do it.
Realistically you can do everything you're most likely coming up with right now with any of these two languages. Just pick the one you like more right now and do something with it.
A question for the functional-oriented programmers:
For f: a -> a -> a, n: a and a list of a, knowing that f is an associative function, that f is not commutative and that n is the identity element of f, is it always possible to rewrite a left fold of the list through f with n as a right fold of the list through f with some n'?
>>54426069
Don't listen to this guy >>54426108
All serious projects are written in vbs. You shouldn't listen to anyone suggesting meme languages.
>>54426149
>and that n is the identity element of f
and that n is NOT the identity*
>>54426149
https://youtu.be/Ccoj5lhLmSQ
>>54426149
f - (associative) closed binary function
n - identity
so you've got a monoid (a, +, n)
you can fold over a list with a monoid
not sure what you mean by the last bit
do you mean is it possible to do both a left and right fold? yes
do you mean can you perform a left fold through a right fold?
normally i'd say probably but people keep saying there are differences
>>54424171
Better:fn is_letter(l: char) -> bool {
match l {
'a'...'z' | 'A'...'Z' => true,
_ => false,
}
}
fn main() {
let l = 'z';
let one = '1';
println!("{} is letter: {}", l, is_letter(l));
println!("{} is letter: {}", one, is_letter(one));
}
Even shorter:fn main() {
let l = 'z';
let one = '1';
println!("{} is letter: {}", l, l.is_alphabetic());
println!("{} is letter: {}", one, one.is_alphabetic());
}
What is the fewest lines of code needed to completely brick a computer?
>>54426226
A visual example might help:
Say I have this, with the aforementioned properties:
f( (f (f n a) b) c)
Then is there always an n' that makes it possible possible to rewrite this as
f ( a ( f b (f c n')))
? It's trivial to show that any left fold (resp. right) can be rewritten as a right (resp. left) one, but that would involve reversing the list (and since f isn't commutative, passing something like g y x = f x y to the function instead), which I want to avoid.
>>54426292
no, almost certainly not
>>54426231
>is_alphabetic
https://github.com/rust-lang/rust/blob/bed32d83fcd1337e962a58fd04fae6b8503e3283/src/librustc_unicode/char.rs#L449
>>54426329
that's what my intuition tells me, but I can't help thinking there might be some way to do it if we know that f has an inverse element or something. I just wanted to know if anyone had proper proof of this (or knew where to read up on stuff like this).
>>54426382
I can't think of any example where this would be true
+/* are commutative and -// are not associative
>>54426359
I was interested in how is_alphabetic is implemented and I just liked the comment and pasted it here, tagged you because you used the function not as a response or an invitation to discuss anything

"""
You see, when a Java programmer gets used to TDD, they start asking themselves a very important question: "Why am I wasting time satisfying the type constraints of Java when my unit tests are already checking everything?" Those programmers begin to realize that they could become much more productive by switching to a dynamically typed language like Ruby or Python.
And that's exactly what happened in second half of the first decade of the current millennium. Tons of Java programmers jumped ship and became dedicated dynamic typers, and TDDers. That ship-jumping continues to this day, spurred on by the fact that salaries tend to be higher for programmers of the dynamic languages.

Because the compiler is multiple orders of magnitude better at checking type constraints for you automatically. Why change to a language that makes you need to write test for type constraints when you can use one that does that automatically?

Having a problem with executing a java distribution on Raspian. The folder is made up of a jar file, and a handful of subdirectories containing resources, such as 'Movies', 'TV Shows', 'Resources' (contains fonts and images). The jar runs fine on Windows, but when I move it over to linux, I'm suddenly getting 'FileNotFoundException's when I try to read in a file from one of the subdirectories. It's almost as if it isn't searching in the relative directory, but expects '/home/pi/Desktop/Media-Center/TV Shows/series-list.json' as the filepath, rather than just 'TV Shows/series-list.json'.
Hi /g/, starting out. I have been working on Codeacademy's Python course, and got stuck on a seemingly simple exercise: a function that returns the median of a list. Here's what I wrote:
def median(li):
m = 0
pos = int (len(li) / 2)
if len(li) % 2 == 0:
m = (sorted(li)[pos] + sorted(li)[pos+1]) / 2.0
else:
m = sorted(li)[pos]
return m

Does the letter case match in the program and the directories? Windows is case insensitive whereas Linux is case sensitive so that could be it. Also what happens if you try to prepend ./ if it's not case issue.

My wild guess would be that len is 4, while indexes start from 0, so pos is 2, and you average the 3rd and last number from the list.
What's the consensus on Elixir. I've been playing around with it for a few days and I like it.

Yes but there's no way median out of 4, 5, 5, 4 could return 5.0 so I assume they chose wrong word whereas average returns the expected 4.5.

Well two more things that you could check for:

2) If the files have proper owner/permissions

whats the cwd of the jar when you run it with the jvm? (its probably looking at System.getProperty("user.dir") which you can change with -Duser.dir )

>>54428642
Oh forgot to say why.
Muh keybindings.
>>54425468
wow thanks you really shed some light on the whole programming thing
>>54428606
vim because comfy
>>54428606
i use spacemacs since it's emacs with better defaults out-of-the-box. emacs (or (neo)vim) is the best choice in general since there's huge support for plugins and the editor is 100% configurable. for example, in emacs i have it configured to do provide syntax highlighting/checking, live error feedback from compilers, and autocompletion for most of the languages I use. i can also use it to track info for git repositories or help with planning ideas (org-mode). plus i can basically replace the rest of my computer with it cause i can run a browser, irc client, and shell in it all simultaneously :^)
>>54428606
emacs
emacs
>>54428606
i started with nano and now I refuse to use anything else because I have Ctrl+O/Ctrl+X muscle memoried so hard I can't use anything else.
>>54428723
that was me for a long time. i went through a MNML phase and just used nano without syntax highlighting. eventually i sort of forced myself to start using emacs for fun and i ended up liking it a lot more. although i still do small edits with nano by habit.
>>54428723
>programming with nano
can nano even have plugins/etc?
>>54428606
Emacs
>>54428697
If you are interested, the next version of emacs is going to get a fully graphical browser that supports javascript. You can use it now if you compile emacs from the git repository, and run "xwidget-webkit-browse-url"
>>54428723
nano is like emacs-light when it comes to bindings
if you use readline a lot, the defaults are emacs-style keybodas (C-e, C-a, C-g, C-d, etc)
>>54428697
I tried going from vim -> spacemacs but I just couldn't handle the bloat
>>54428764
Why do you need plugins for?
They lead to excessive tinkering with the editor instead of doing anything useful.
>>54428807
Not him, but I need a fuzzy file finder plugin.
>>54428770
>If you are interested, the next version of emacs is going to get a fully graphical browser that supports javascript.
that sounds pretty sweet, although i mainly use emacs over ssh because i do half my computing from windows and refuse to figure out how to rice emacs on windows
although that may be enticing enough to get me to finally install nixos and ditch windows
>>54428785
meh, i dont really give a shit about bloat that much. i kinda just think of it the same way as i think of the rest of the OS, since that's basically what emacs is like for me. in general, i rarely use more than 3-4 different programs on my computer (the others being mpv, firefox, and telegram) so it's not that much of a concern for me that some of them are bloated
>>54428870
isn't that what locate is for?
>>54428894
>mainly use emacs over ssh because i do half my computing from windows and refuse to figure out how to rice emacs on windows
I don't know if you already know this, but emacs lets you edit remote files directly from your machine through TRAMP.
C-x C-f /ssh:user@host:/path/to/the/file
I agree, emacs on windows is a pain. If your machine can handle it, it may be a good idea to install linux on a VM, get emacs on that VM, and then use the graphical version.
With vim, it doesn't matter if you use the terminal version or graphical version, because both have about the same features, but there is truly a world of difference between terminal emacs and the graphical one.
>>54428928
What do you mean? AFAIK locate is not part of vim, but it's a GNU utility.
>>54429000
just use the shell
>>54429021
But ctrlp also lets me decide how I want to open the file (replace current, new tab, split, vsplit).
hi where are the feminine penises xd

>>54428606
vim, because modal editing is the most comfortable way to edit.
>>54429071
I'll post it on Github: https://github.com/baspalmer. It's not there yet, but I'll create the project this evening.
>>54424540
Just curious, what will this project have over something like rutorrent?
Sorry for the scrub question but is this going to work?template<class T>
static inline T NextItem(const vector<T>& Array, int CurrentIndex = 0)
{
if (!Array[0]) return nullptr;
if (CurrentIndex >= Array.Num() - 1 || CurrentIndex < 0) return Array[0];
else if(T X = Array[CurrentIndex + 1]) return X;
else return nullptr;
}
It should iterate through an array, and when it reaches the end go back to the first index. If there's no element at the first or at the next index, then return null.
Not expecting a solution if it won't work btw, just a quick answer.
>>54429229
>if (!Array[0])
should be
if (!Array.size()) return nullptr;
or
if (Array.empty()) return nullptr;
What's "Num()"?
Also, CurrentIndex should (presumably) be unsigned
>>54429254
Thanks, Num is just like std::vector::size

If T isn't a pointer, this isn't going to work. If T is a pointer... why do you have a vector of pointers?
>>54429316
T is always a pointer, and vector isn't STL's vector. Why shouldn't I have an array of pointers? I've been doing it all the time.
>>54428964
yeah, it's just that setting up spacemacs is weird as fuck on windows and i can't get autocomplete for any of the languages i use because that requires the compiler to be installed to the host OS (and not cygwin/mingw). i do have a linux VM actually, but the graphics drivers(?) broke emacs
>>54429214
They solve different purposes. rutorrent is 'just' a front end for rtorrent.
My program lets you manage the torrent files and the (in)complete downloads. It basically read/deletes/adds files on the file system. Unlike rutorrent, it doesn't display the status of the download. It only displays if the download is (in)complete.
>>54429529
EDIT
It's basically a specialized OwnCloud.
>>54429344
>T is always a pointer
T could be any type, even a non-pointer type. T* is always a pointer.
>Why shouldn't I have an array of pointers?
If those are pointers that your vector doesn't have to manage, they're fine. If you're just arbitrarily heap allocating pointers and shoving them in an array, consider having an array/vector of the actual object itself and not having unnecessary indirection.
>>54425468
>>54425492
>>54425561
You see, there are millions of 'programmers', but only a select few 'Computer Scientists'. One must engage with the world's API flawlessly, mastering the various data structures and algorithms you must use to achieve your goals. All you life 'programmers' would rather rely on the bloated kludgey jQuery libraries in your life-- coffee.js, sports.js, gf.js-- which is fine, really. Every life Computer Scientist needs a few code monkeys to manufacture bugs which only our brilliant minds can crack.
>>54426069
Python and C++ are the only languages you should consider for most new projects. Exceptions:
>you're interfacing heavily with an API in a certain language (web app, for example)
>you need some craazy performant code

I refreshed my page while typing a huge response to this but to put it concisely you are dragging in an entire library to solve a simple requirement(that the library -happens- to have in its blast radius) and at this point most of your code will just be mediating between libraries to get them all to "play nice". This is what happens when someone falls for the "just use ______" meme on stackoverflow when they really just want one simple problem solved or need quenched.
>>54430762
