Newbie here, can anyone sort of tl;dr how posting programmatically to 4chan works? I see that 4chan has a read-only API which returns json (?), and I think I can learn how to parse/work with that easily enough using Google, but I'm unsure of how actually submitting posts works. It it just http get/post with some fields or something? (Firing from the hip there.)
I'm new to programming and I'm interested in making a 4chan client as a pet project and to learn JSON, etc. I just need someone to point me in the right direction so I can Google it / learn on my own.

Pretty much, yes. When you fill out the post form + hit submit, it sends the form data to the server via a post request. To figure out exactly what, use the "inspect" functionality of your browser and go to the network tab or similar. Post a reply to 4chan and monitor the traffic for changes, you should see it report that you sent a post request and it'll tell you what data you posted. Figure out how it relates to the form you sent in and how to create it programmatically. Then all you have to do is send post requests with said generated data (plus 4chan pass/catcha shit).

6/10 nice beginning. You did some C/C++ before didn't you?
You don't need to specify iota more than once. That's the nice thing about it. Also I'd say you could have atype state intin order to be more idiomatic. Read https://blog.golang.org/constants it's enlighting.
Put these magic numbers out tho.
Now do it with a goroutine, it's a more elegant form of statekeeping. (Keep the loop but send values into a channel from it)
>>54019391
Also: I'm not really into the idea of checking m then mo then mod but suddenly not mode for a meaning as an operator, both because m and mo are stupid and mode has been opaquely cut off of the lexicon. The syntax should unambiguously delimitate operators, then they should be recognised IMHO.
And why are you appending to the beginning of the stack? I'm not saying it doesn't work, I just find it unidiomatic...

>Tfw no refugee key

>>54019802
We call them foreign keys.
>>54019766
Basically, instead of using the 'real-world' identifier, you arbitrarily create a unique key to refer to a thing.
For example, in my image, each Computer has a unique ID by default. The application will not (read: should not) create two of the same ID.
In this case, the primary key of the table is ComputerID.
If I were to redo the table to use a 'Surrogate Key', I would create a sequential generated key for each row, that is essentially meaningless, other than "Here is the unique identifier."
Another prime example would be to use Social Security numbers as a primary key. It should work, in practice, and it's also meaningful.
>>54019810
>>54019823
You know, in hindsight, the ComputerID in my example is actually a Surrogate key, because it is inherently arbitrary due to the field being auto-increment.
Best example:
- Social Security Number / Credit card number as primary key = natural
- Auto-increment or generated unique ID = surrogate

Of course I did, I just wanted to know what happens if you actually execute these functions.
>>54021361
>I just wanted to know what happens if you actually execute these functions.
If you ACTUALLY read my post, you'd know that executing int13h;ah=41 is successful and reports that the extensions are supported, but then executing int13h;ah=48 directly after fails with function not supported.
I'm not sure what you're getting at, but I AM executing the functions, and this is the result I'm getting, but it's not supposed to be like that, and this is driving me up the fucking wall.
How do I check whether a non-blocking socket has connected or not? The code I'm using is this:sock = socket(AF_INET, SOCK_STREAM | SOCK_NONBLOCK, 0);
...
if (connect(sock, (struct sockaddr *) &saddr, sizeof(saddr)) == -1 && errno != EINPROGRESS) {
// Raise error
}
...
int sock_err;
size_t sock_err_len = sizeof(int);
getsockopt(sock, SOL_SOCKET, SO_ERROR, &sock_err, &sock_err_len);
The connect() call raises an error, which is EINPROGRESS naturally, but I can't seem to get that with getsockopt. For me, getsockopt only returns 0 as in, no error. Trying to send or receive data using the socket results in EAGAIN, as the socket is not yet connected and ready.
Any ideas, /g/entlemen? I guess I could make a recv call with MSG_PEEK and check the value, but it seems kinda clunky. Then again, this is linux.
>>54021417
>you'd know that executing int13h;ah=41 is successful and reports that the extensions are supported
>>YET int13;ah=41h STILL FUCKING REPORTS ERROR AND SETS AH=1
Should I learn C++ or java? I have small knowledge of python.
>>54021462
Sorry, that was a typo, I meant to say int13h;ah=48h still fails
I apologize for that.
int13h;ah=41h succeeds and reports that it supports all the features I need, the "API subset support bitmap" in CX explicitly reports that ah=48h is supported (bit 2).
Yet despite that, int13h;ah=48h still fails with CF set and AH=1 which means that the function is apparently not supported DESPITE AH=41H REPORTING THAT THE FUNCTION IS FUCKING SUPPORTED.
This happens in QEMU, Bochs, and on real hardware (thinkpad x220).

That is the simple way, unless you want to have a string for the team's name inside of the object, i.e. self.name = "Chelsea", and then loop through them until you find a match, but the dictionary is a better idea I think; Python uses hash tables for dictionaries if I remember correctly (I mean why wouldn't it?) so lookup would be much faster than looping through them
The one line where you create the dictionary is probably long and ugly but it's the best way to do it as far as I know

Can you expand on that? I thought goroutines were just for multithreading reasons, and it's not like I can parallelize this.

And I've printed the drive number and it's 0x80, so that's not wrong either.

Quick, /g/. I have a presentation to do in half an hour for college. I'll be presenting the application to a group of professors pretending to represent my client. And the application I'm presenting is unfinished due to my own mistakes.

some turnbased RPG for school assignment. listbox3 is supposed to show the attack's damage, how many mp's were lost, etc after you click the attack button.
question is, how do I insert the text? tried using but it didn't workif (listBox1.SelectedIndex == 0) //uses spin attack when clicked/highlighted
{
progressBar2.Value -= 16; //mp cost
progressBar3.Value -= 10; //damage to player 2
listBox3.Text = "this dealt x damage and shit ";

I'm not really familiar with java but could it be because you only have one scan(): instead of two after each scan.nextX()?

Working on a badly written assignment, maybe you guys can help me understand, I'll skip the unimportant details, basically at one point I need to 'create an arraylist with exactly one instance of the six objects added', then initialize said arraylist with at least 2 products (it's kind of an online store simulation) of each type (object).ArrayList <Device> available = new ArrayList <Device>();
Type1 ty1 = new Type1;
Type2 ty2 = new Type2;
...
...
Type6 ty6 = new Type6;
available.add(ty1);
...
available.add(ty6);
So, this would be the first part, but how do I 'initialize it with at least 2 products of each type' when I just initialized it with 6 instances?
>>54022112
Let me rephrase my question, is it asking me to initialize it with 12 instances after I've already done it 6? Or is each of 6 objects supposed to have a list of their own? (this isn't specified at all)
print("1\n2\nfizz\n4\nbuzz\nfizz\n7\n8\nfizz\nbuzz\n11\nfizz\n13\n14\nfizzbuzz\n16\n17\nfizz\n19\nbuzz\nfizz\n22\n23\nfizz\nbuzz\n26\nfizz\n28\n29\nfizzbuzz\n31\n32\nfizz\n34\nbuzz\nfizz\n37\n38\nfizz\nbuzz\n41\nfizz\n43\n44\nfizzbuzz\n46\n47\nfizz\n49\nbuzz\nfizz\n52\n53\nfizz\nbuzz\n56\nfizz\n58\n59\nfizzbuzz\n61\n62\nfizz\n64\nbuzz\nfizz\n67\n68\nfizz\nbuzz\n71\nfizz\n73\n74\nfizzbuzz\n76\n77\nfizz\n79\nbuzz\nfizz\n82\n83\nfizz\nbuzz\n86\nfizz\n88\n89\nfizzbuzz\n91\n92\nfizz\n94\nbuzz\nfizz\no7\n98\nfizz\nbuzz\n")

>>54022089
Nothing complicated but requires a lot of code.
Since java components doesnt have a method that indicates if its focused i had to create my own
Why?
Simple, every slider have a onChange Listener so for preventing unwanted behavior every time a value changes checks what component is focused, ej. If a CMY component is focused when it changes it's value it will update all the other sliders and text fields without triggering the main purpose of each onChange listener because it's focused only in a CMY slider.
I will upload a screenshot of how updates its values

How do I learn assembly?
>>54022705
Implement sprintf in x86 assembly, then do something practical.
My advice: Only use assembly when it's actually needed.
>>54022685
Holy shit, you are hopeless.
I am asking what GUI framework you are using.
For example, to create a C# application on Windows, there are multiple Graphical User Interface frameworks you can use to construct the front-end of your application. Two examples would be WinForms or WPF.
If you're programming to be cross-platform (usable on Linux and OSX), you could be using WinForms or GTK#.
How are you showing the user your program? Does your interface code look like more C# or does it look like HTML?
>>54022730
I think learning assembly is a very niche thing that could be valuable to companies who deal with embedded operating systems.
>>54021916
>You did some C/C++ before didn't you?
that was because of the enum into int you did. That's interesting tho.
>Can you expand on that? I thought goroutines were just for multithreading reasons, and it's not like I can parallelize this.
Not only. Concurrency is not parallelism (that was the title of a Rob Pike talk btw. A controversial figure on /dpt/). It is a way of structuring programs. Goroutine is a pun on coroutine, which was named in contrast with subroutine, that's what we call procedures. When a subroutine is called, the local variables, precise state of execution and the like of the calling routine are saved, and the subroutines begins executing. The calling routine will never resume before the subroutine is destroyed tho, which allows us to structure them as a stack but hides some interesting patterns of interaction between the two, if we could just save the state of the subroutine and return to it later. You've probably already seen the generator functionnality of python, which is a restricted form of coroutine, and you've surely seen some in Lisp, like I have. With coroutines you can express non-continuous but stateful processes in one go. I drifted but you should definitely try it. I realised a lot of things by doing so, even if the implementation of these things didn't necessarily involve actual coroutines.
>was working in Lisp yesterday and I wanted to use a cons.
Crossed my mind. Lisp for the win!

You call a method that you've made the same way you would call any other method. Since the method returns the value it generated you can assign it to a variable in main like this:
>>54022631
import java.util.Scanner;
import java.util.Random;
public class Helloworld1
{
Scanner scan = new Scanner (System.in);
public static int randInt(int min, int max) {
Random rand = new Random();
int randomNum = rand.nextInt((max - min) + 1) + min;
return randomNum;
}
public static void main(String[] args)
{
Scanner scan = new Scanner (System.in);
randomNum = randInt(1, 25);
System.out.println(randomNum)
}
}
I don't actually use Java but that should work.

Is java the best programming language to learn in 2016?

It'll definitely get you a job. But any of the more popular languages will be able to do that. Worry less about best and more about what you want to do specifically. Pick a language based on that.
>>54023137

>>54021929
I took a little time to review your program, and the wrong parameter seems to be the SI register. I can get the function to return successfully by removing the drive_no byte. So it looks like the problem is related to data alignment. Yet, if I align the disk_params buffer to any word-aligned address but 0x8c, the function fails again... Weird, I'll investigate a bit more because it's really intriguing.
>>54023146
There's a lot of resources available for Java and a very large community so you'll definitely have that as a perk. It was the first language I learned in an online class back in high school but I didn't like it a whole lot. Though that doesn't mean you won't.
I personally recommend Python when people ask me the best way to start learning. Python is easy to get started with (after you get it installed, which can be somewhat frustrating on Windows, but is less annoying if you use Anaconda) and has a great community with a lot of resources and is a higher level language so it's easier to learn than some of the more 'bare metal' languages.

I am really confused about it.
I finished a Google course about android development that used the SQLite, ContentProviders and SyncAdapter, but the boilerplate code is pretty bad.
So I decided to search for alternatives and found a video of last year's Android Dev Summit talking about a UX oriented architecture where your UI interacts with a local database that is synced with a remote server with Jobs.
Now I don't know what to use.

This is a strange question:
Is there a "language" built to better interpret the English language?
Like something that exists between a programming language and the English written language. Something that could take in written English and reconfigure it so that it becomes easier to extrapolate data from.
"I was doing XYZ with ABC and her 123"
This language interprets the sentence and knows that:
>the user was doing XYZ with ABC
>ABC and 123 go together
>ABC is female
>XYZ is a verb
>ABC is likely a friend
Then passes this info to deeper programming functions.
Or am I thinking of bullshit and this is just higher-leveled programming?
>>54023978
Maybe Linq.
>>54023978
The English language is undecidable. No such interpreter can exist.
Countless very complicated statistical-based processing methods can attempt to "learn" English semantics, but no implementation has ever come close.
