Working on a site that captures and keeps up to date Youtube channels and videos. Displayed chronologically, sortable by country, gender, popularity etc. The next step after capture/display is solid is to integrate youtube-dl for automatic archival.

On second thought, I may be able to use CMake comfortably for building Java shit... as long as that Java shit isn't running on Android.

When writing a database schema for an *chan site, would you keep a single table holding all the posts along with the columns "is_parent", "parent_id"?

Or would you rather have "threads" and "posts" as separate tables and every row in "posts" has a "parent_id" pointing to a thread in "threads"?

I was going to spend the week learning python but I was just thinking if it was better to get into web dev, I learned programming basics in college, I know basic C, C++ and Java and basic python syntax that I learned by myself. What would be better to invest my time into?

>>56912689

What data does a thread have that can't be expressed through posts?

Some I can think of are number of posters/posts/images/pages, which can all be dynamically calculated

>>56912722

>>56912748

Either when the page is loaded/cached, or each time you update a thread table. Since it's useless data (imo), you could even push calculations client side.

>>56912722
I'm thinking it would be easier to prune posts and/or move them to an archive.
To move to an archive, I can just move the thread entry to an "archive" table, leaving the posts in post untouched until it's time to prune.

The more I look into how CMake works and what it can do, the more I find myself willing to use it. Even if the outputted makefiles are atrocious.

>>56914232
I can confirm it's better than autotools

I've also heard you don't need to do any fancy build shit to make stuff work on Windows, so you can focus on keeping your copious buckets of

#ifdef WIN32

in your actual code

>>56914251

I never really ranted that hard against it. I just found it way too fucking complicated. And it is kind of a fucking weird tool to work with, but it's less weird the more you work with it.

>>56914271

You do need a little bit of work to make things correct on Windows, because the default is MSVC, and MSVC is always the wrong choice.

>>56914286

By virtue of CLion using it, I've come to love it.

Developing with C on Windows is still AIDS, though.

>>56914307

It's less AIDS with MinGW-w64, but then you're left with

>msvcrt.dll dependency

Honestly, it really should come with its own statically linked libc, even if it does mean applications will be a bit bigger.

That build issue had nothing to do with the flags, trust me. It was more to do with which version of the lib was actually going to work, and there's about 300 different setup guides on the SDL site and forums alone that give differing suggestions.

In any case, I eventually got it working with some minor trial and error.

Package managers streamline programming to an unbelievable degree. That shit just works.

>>56914262
Consider taking a peek at it on google books or something. There's maybe a small section with some C code in it and the rest is literally going through the grind of setting up CMake and the toolset to which it would belong.

Pretty much every system function needed to implement libc on Windows is in kernel32.dll and well-documented.

>>56914617

Makes me glad I'm no longer using Windows on my main laptop :)

But I still have to use Windows for my research, and VMs are a bitch to work with.

>>56914262
Oh yeah, I don't mean to shill but I do feel that book is part of the C trifecta. K&R, ANSI C and 21st Century C.

>>56914642
>Pretty much every system function needed to implement libc on Windows is in kernel32.dll and well-documented.
then use them directly.

>>56914640

So it's pretty much just a CMake book disguised as a C book?

Also, I don't even know you, Anon.

>>56914661

The purpose of the C standard library is to abstract away the operating system for the basic tasks of I/O and memory management. If the user program is directly interfacing kernel32.dll, the program is more or less locked into using Windows.

Also, the Win32 API is fucking nasty, and should be avoided for application programmers.

If it weren't for vidya, I'd have no reason to use Windows.

>inb4 QEMU

>>56914682
then use the crt library

>>56914691

QEMU runs like ass, GTP. It's good for OS development, because of its support for shit tons of languages, but if you want to run Windows in a VM, use either VirtualBox or VMWare.

Actually, don't do VMWare. I tried getting Windows 10 installed on VMWare today (in hopes that it won't be as much of a pain in the ass to get networking working on as VirtualBox was), and regardless of whether I used the ISO from Dreamspark or the one downloaded through Microsoft's Windows 10 download utility (and there was a 1.2 GB difference in these files, so I assume one of them is more up to date), the result was the same: KMODE_EXCEPTION_NOT_HANDLED boot loop of death.

>>56914754

Yeah, that's what mingw-w64 already uses. The problem is that it uses msvcrt.dll for portability or some shit, but that version is frozen in fucking time and as such does not have the ability to do some C99 and C11 things that mingw-w64 is capable of doing. What I'm suggesting is that they should implement their own libc, rather than using Microsoft's.

>>56914771

That's sort of my point. I'm not going to go through the effort of setting up passthrough when I can just use Windows.

>>56915230

That seems like it might be an accurate number if you don't take into account the number of novice programmers that seem to ask the same questions every time. Surely, it is not all one dumbass that never learns.

What kinds of maths are involved with programming, also what are all the types of programming styles. Please give links, thank you.

>>56912637
haha ur gay

>>56915261
There's a lot of stuff, if there's one thing that's particularly "programmer-y" it's discrete math, which I *think* covers the bitwise logic shit that doesn't really show up elsewhere

But it all boils down to what you're trying to do

So the question is, what are you trying to do?

>>56915261
It really depends on what you're trying to do.
For example, if you're doing anything graphics related, you need to know linear algebra.

>>56913926
Supreme taste my friend.

>>56915261
In a more concrete sense: you use graph and queue theory in networks, linear algebra in 3d graphics, information theory in compression, number theory in cryptography, category theory(I think) in programming language design(specifically for data types), statistical and high-level algebraic methods in AI... the list goes on and on.

>>56915261

Programming on its own is just algebra. You will likely need more depending on what you are doing. At my university, a Bachelor's Degree in Computer Science requires 45 credits of math and science, of which, some will be satisfied by certain mandatory mathematics classes in linear algebra, probability theory, discrete mathematics, and calculus. I never found much use for calculus. Certain other types of mathematics are also taught as computer science theory (though we do not count them for mathematics credits), which includes complexity theory and graph theory, among others. Beyond that, I know that....

Any subject that involves learning algorithms, whether it be artificial intelligence, natural language processing, data mining, etc... requires knowledge covered in some higher level statistics classes. I took more statistics than I needed for the degree requirements, and it certainly has helped out in a number of elective classes I've taken.

Encryption is all just applied number theory, and consequently, is when math starts to get fun (at least in my opinion).

Computer graphics requires one's knowledge of linear algebra, and I think calculus to be rather air tight.

And other subjects will have their various requirements.

>>56912619

in Meme++, what's the normal case style you guys use for most things?

atm i'm just lost and i wish this language had some kind of fucking standard

i come from java which is a language full of pajeet standards but in C and C++ you'll grab some framework which uses camelCase and then another that's like snake_case and then you have some stupid bullshit that i see in microsoft pajeet code where EVERYTHING is PascalCase

what do i do

i've been thinking of:

namespace::Class::onFunction()

namespace::Class::STATIC

or

Namespace::Class::OnFunction()

Namespace::Class::Static

but then the latter looks like shit when you just call something regularly like

m_thing.Draw();

Nothing in C++ is normal, and none of its users can agree on standards. Hence why it is perfectly acceptable for it to be a kitchen sink language.

>>56915828
>...does EFI provide a standard way of setting a video mode?
Yes but you can't use it after calling ExitBootServices, which is around the time where you jump to your actual kernel. so, 100% useless.
You could not call ExitBootServices, but then your OS remains a "UEFI application" and you do not own the system, the UEFI does.

>What data does a thread have that can't be expressed through posts?
Whether the thread is a sticky, for one. You could tag that as yet another flag on an OP post, but at what point do you say that it's fine for you to have 19 trailing null values on every non-OP post?

There's also the consideration of performance.

With thread and post tables you can add clustered indexes on each one, so that the data is stored sequentially on the hard drive (faster reads than a non-clustered index).

Due to the sequential nature of post numbers, and the lack of editing, the advantage in nonsequential insert and update that a non-clustered index has is nullified in the case of an image board.

I'd almost propose a simple API, one call to return a pointer to a scannable list of valid modes, and another to set that mode...

But then I'd probably end up just reinventing VBE.

The issue here is most likely that DOS is hardly used these days - VBE was important purely because DOS programs tap the hardware directly. That, and there aren't a dickload of x86 graphics chip manufacturers these days.

Until even VBE gets ripped away from us, though, we'll have to keep using V86 monitors.

Learning PHP. Messing with PDO for the first time.

So I fetch all rows from my table, right? and now I want to sort those rows by type into two arrays.

      $result_set = selectAll();
      $item_data = array( 'Books' => array(), 'BoardGames' => array() );

      foreach( $result_set as $row )
      {
        if( $row['ItemType'] == 'Book' )
        {
          $item_data['Books'] = $row;

        {

Absolutely perfect.

>But then I'd probably end up just reinventing VBE.
VBE doesn't fucking have it (it's optional, which means it basically doesn't have it). so you wouldn't be.

But actually getting your proposal accepted (and implemented on most cards) is probably a pipe dream, unfortunately.

WebGL is not something to be handled directly unless you know how to set up a GL3 or GLES2 pipeline and that involves writing shaders and shit

>>56916148
It's not hard to prove but I can't be bothered explaining the code to you (and I struggle with formal proofs).

I'll give you a hint:
x = [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, ...]
x_remove = x * x[0] = [4, 6, 8, 10, ...]

x_remaining = x.remove(x[0]) - x_remove = [3, 5, 7, 9, 11, ...]

Repeat the same procedure using x = x_remove
(when you get to x[0] == 7 you will find those magic numbers)

>>56916007
You are setting the index 'Books' equal to each new row that you get. What you want to do is append each row to the index 'Books'.

Try
$item_data['Books'][] = $row;

Assigning to an empty index like [] appends an item to an array.

There's nothing 'cuck' about wanting to bone brown women, though. Wanting to the be the person doing the fucking is, quite literally, the opposite of cuckoldry.

>>56916188
Have to correct
>Repeat the same procedure using x = x_remaining

@ x[0] == 7 You will have the following pattern:

x[1] = x[0] + 4
x[2] = x[0] + 6
x[3] = x[0] + 10
...

The pattern repeats every 30 values, the loop starts at 37 because it is faster to pre-check (before doing other optimization things) for primes between 0..37

Am I correct in saying that atomic operations on a database ensures synchronicity of data?

>>56916243
It depends on whether those atomic operations are performed on the data that you want to maintain 'synchronicity' (I would prefer to maintain data validity and prevent erroneous implementations due to read-write conflicts where data is changed shortly after a separate thread reads it)

>>56916193

Adventures with scrum & git 2: electric boogaloo

Asked a developer to pull in a library. They make a pull request. In this pull request, he has added the link to a CDN which provides the minified version of the library. Since this is a project that will be abandoned, but the CDN/library will change, this isn't acceptable. I request that they import the developer version, with plaintext javascript and css.

Next thing I know, a single css file is now added to the MASTER branch. They merged it to master, without creating a pull request first.

They tell me that they will revert it. After a bit, I see a new pull request. The request is to add a new commit which simply deletes the offending files, without actually reverting the merge.

Alright fellas.

I'm working on a program. I managed to scrape together an algorithm.
Task is:
Given a set of integers and a sum N - calculate whether any subset of these integers equals the sum, then print out that subset which satisfies the condition.
So If I have an array {5,10,20, 50} and I want to check for 70, it should give me back 20 and 50.

The code is here
http://pastebin.com/fJkj3uT8

My problem is I know fuckall about C++, coming from Java so it's practice.

What I got down is the algorithm but the way it is implemented is
>put in the array length
>put in all the ints for the array
>put in the desired sum
>run

I want to make it so
>there is an int.txt somwhere (empty or not)
>program asks whether I want to input numbers
>if yes, writes those ints to the file
>else proceeds to the algorithm READING the ints from the file (I though about pushing ints from file to vector but dont know how to)
>prints in console all possible solutions

now i've been all over SO or google but I can;t find anything concrete on actually integrating the file thing in the program.
Where does the file go if it gets created? (default directory)
Like say I want to compile this program into an EXE, have it execute, console window pops up, there is no file yet - I say I want to input ints, put in the ints, save them to a file, run algorithm, give results.
Another time open the EXE, want to add another set of ints to the already existing int set in file - so append some more ints and then run it.

with asm.js, which builds right on top of normal Javascript and already works, you take a small efficient subset of Javascript and use it as a compilation target in the same way that you target any other platform.

For example, instead of translating C code to x86 assembly, you translate it to this Javascript-based "assembly" syntax.

The "trick" is in how this small subset is much easier to optimise for than full-fledged Javascript while still running on top of normal Javascript VMs.

>>56922444
Thank you for replying. I have no problem decoding from base64. Since the line break character isn't a valid character in base64 I was wondering why it was in the file in the first place and if it should be ignored (removed before decoding). Is it it maybe common to put line breaks in base64 encoded files for readability?

You are probably erasing more elements than you have. Did you mean

for (int i = 0; i < dimList.size(); i++) {

?

Incidentally, while I have no idea what your code is supposed to accomplish, if you are continuously erasing the start of a vector you should probably use a different data structure.

Which programming style is best for python? Functional programming?

>>56922655
I don't really know much about the topic, but my guess is that, yes, you could simply remove the newlines. in fact, you could do some little test:

$ python -c 'print("D"*10)' | base64 -w 0; echo
RERERERERERERAo=
$ python -c 'print("D"*10)' | base64 -w 5; echo
RERER
ERERE
RERAo
=

as you can see, these things are equal, except for the newlines
and yeah, it's probably done for readability

You can try California for that.

We don't do H1B's here unless you're white or asian.

I am white. But ok, I'll try california -- or seattle works too, I hear.

really boggles the mind that no one's made a programming language that consists of a DFA and 2 counters honestly, why would you need more anything else is bloat

You stackoverflow until you memorize all of the commands you need to get the job done.

>>56923711

That's how I'm learning Rails for my senior project. :^)

>>56923668
>seattle works too, I hear.
That, and more specifically, Redmond, if all you care about is getting the H1B.

The other option would be to try one of those mid-market firms in nice smaller towns.

I almost took a job in Idaho Falls, ID because of this. Nice rural town full of rich people.

In any case, any tech-centric town that skyrockets in prosperity is going to be quickly inundated with undesirables. See: San Francisco, Seattle, Austin

Anyone here familiar with Excel VBA?

I need to copy the first ten values from a row and then display those values in the next row using an array and a For/Next loop. The book actually shows you how to exactly how to do this with columns, but I'm a fucking moron so I'm completely lost on how to do it with rows.

Thanks in advance!

>>56923731

That's terrible... why are you using Rails?

>Your markov chains are shit.
I'm just scanning 4chan as a whole, the prefix size is only 4. I think it might be suffering because posts are so short and there's so much unique terminology. That, and I'm forcing it to start sentences with sentence beginnings (if it couldn't form a chain from the end of the last one) and to end with sentence ends.

I'm going to move to a new model soon where it just takes words with no regard for sentences and then ensures that they follow legitimate grammar formats. Would that likely produce better results?

>>56923867

Well, pretty much everyone does web apps for senior project, and one guy in the group said "Okay, we're gonna use rails!" and I was like "whatever, duderino." and that's how it happened.

>>56923838
>The book actually shows you how to exactly how to do this with columns
If you're using Walkenbach's book, give it the old trial and error and just substitute column for row in his macro. There should have been a CD/DVD of samples he provided, too. All of his macro code is actually really portable.

Do you know how to program outside of VBA?

>>56923927
It kinda sucks that everything has to be a webapp these days, but it makes sense.
Most people never leave their web browser anymore.

What would be the correct way to handle a gigantic amount of parameters being passed to objects that run in a threaded manner? Here's the params
[quote]
private final String threadName, crawlDomain, crawlPattern, imagePattern, startURL, textPattern;
private String workingURL;
private final WebTrie urlTrie, mediaTrie;
private final int maxDepth, assistDepth, id, iteratorStart;
private int workingDepth, pagesCrawled, delay, iteratorLocation;
private final boolean sidedness, backCrawl, gallery, verbose, downloadImages, downloadHtml, downloadText, includeLinks, iterative;
private boolean isFinished;
private final int linkAssist = 5;
private final WebStringUtils webStringUtils;[/quote]

What I'm currently doing is setting these params in the main class as static, then I have public static (synchronized) accessors that each thread pulls from to save into its local variables for accessing without worrying about threads colliding on attempting to access the variables, slowing them down
I used to pass it as a constructor but that got retarded fast

>words

Take it to the next level, anon. Use letters, but auto-correct the words as they are generated if they get mangled.

Then, analyze the sentence for structure add conditionally add helper words like "to", "the", and "of".

After that, analyze each sentence and evaluate how bad the grammar is and throw out anything below a threshold.

>>56923973
Structs exist for this very purpose.
You group relevant variables together and pass a single pointer to a function instead of 20.
This also enables your functions to work on multiple contexts, simply by making an array of structs.

>>56916969
Subtype polymorphism is far more overrated.

struct Expr;

struct ExprOp {
    char op;
    Expr* l,r;
};

struct Expr {
    ExprT type;
    union {
        ExprNum _num;
        ExprStr _str;
        ExprOp _op;
    };
};

This gives the error:

 error: field ‘r’ has incomplete type ‘Expr’
note: forward declaration of ‘struct Expr’

I have to make an AST. what do?

>objects that run in a threaded manner?
Nani?

>>56924037
You're missing an asterisk.

Expr *l, *l;

Will work fine.

new thread kpop edition please

>>56923973
>>56923997
That's too much fucking exposed information for a single object.

I would bet my liver that you really REALLY need to refactor.

An object should represent a single concept, and can certainly be comprised of smaller objects or structs, if it makes sense to do so.

>>56924061
Err obviously that was meant to be:

Expr *l, *r;

Not l twice.

>>56924037
In a variable declaration, the * binds to the name, not the type. So you need to write:

Expr *l, *r;

In C and C++, "Type*" is sometimes a type and sometimes not.

In layman's terms, it allows you to reason about the possible inhabitants of a type, usually a function type. This is important for e.g. optimization.

>>56923999
That sounds like reducing the problem to the point of obscurity but it's a cool concept. I don't think I want to put that much effort into a toy program.

>>56924013
Java doesn't have structs, would passing references to a bean be what I'm looking for? as far as I can tell that's the closest thing to structs that exist.

>>56924054
poor wording. The Objects operate on threads.

>>56924082
All of the params are just flags that the user sets in the command line for the search- they only affect the crawl and the data returned. The object does one single thing, and that thing is access web pages according to the rules that you've set. There actually are several classes in there- Tries, and there's a separate class for actually downloading images (The threads make calls to a manager that spawns download threads), but that's called from within the crawler objects themselves. as far as I can tell, I'm following OOP methodology correctly.

Le 2016

Just started university this fall, they teach C# in the first class, supposedly Java in the second. Learning arrays and loops and whatnot now.

using System;

public class Shitposter
{
    public static void Main()
    {
        Console.Write("What do you want to shitpost: ");
        String shitpost = Console.ReadLine();
        String bigShitpost = shitpost.ToUpper();
        for (int j = 0; j < bigShitpost.Length; j++)
            Console.Write(bigShitpost[j] + " ");
        
        Console.WriteLine();
        
        int i;
        int spaceAmount = 1;
        for (i = 1; i < bigShitpost.Length; i++)
        {
            Console.WriteLine(bigShitpost[i] + new String(' ', spaceAmount) + bigShitpost[i]);
            spaceAmount += 2;
        }
    }
}

Maybe one day I'll actually know what I want to do with my life.

if you're in a loop just have a counter variable every time you read something in

 if(count % N == 0){ print();}

In general the best way to handle it would be to show the guy what he should of done and walk him through the steps to do it right. Chances are he just doesn't know the correct way to go about it. Keep the feedback constructive, no reason to get mad
