that's because callbacks are flexible and powerful while events are fixed and concrete

That's not true, actually!
It's a common fallacy among educated people that they are somehow immune to biais and manipulation, but it's been proven wrong repeatedly.

Educated people are on average slightly harder to pander to since some obvious bullshit might not fly, but everyone's emotions can be manipulated.

>>57445654
>Callbacks are hidden events.
Exactly.
>So it's the opposite anon.
No you retard.
Callbacks is events + hidden event loop dispatching to function pointers.
Events is you coding the event loop yourself, ergo you can easily just call functions if that is what you want.
But trying to get back the event loop (and control how it runs) from a callback-only model is much more difficult (if not impossible).

>>57445667
Thinking that politicians are "dumb fucks" or "retards" is extremely naive.

They know exactly what they're doing.
The reason politicians always talk with simple words and simple ideas is to reach simple people, not because they're idiots.

It would be five times smaller there.

>>57445689
>Callbacks is events + hidden event loop dispatching to function pointers
No, callbacks could be done however the framework chooses.
Consuming iterators - callbacks
Async - callbacks

Anything remotely monadic is basically callbacks

Reading about pipes and conduites in Haskell.
I think I'll go with pipes, since the programmer seems like a nice dude and the tutorial is good.
A year ago or so I had a problem where a program would unexpectedly take up gigabytes of memory, now I know why (forM) and how to fix it (pipes)
Apart from that I need to brush up my knowledge of Monad Transformers.

>Educated people stay away from corrupted or manipulative sources in the first place. They don't subject themselves to pure manipulation. They weight up the consequences of their vote on either candidate and make a decision.
You wish, but it's been shown to not be true at all, sadly.
You'll have tons of very well educated people who only read opinions that agree with them. Engineers in particular are surprisingly vulnerable to this.

>If you are being emotionally manipulated by the media into voting you are not educated and you are not actively seeking out truths. This is a flaw on your part.
That's incorrect. You're wrongly equating being educated with being rational.

At the core of any callback dispatcher is some kind of infinite loop doing the dispatching.
If you have to do the continuation manually yourself (akin to call/cc) then it's not really a callback model.
The main distinction is wherever you are in control of the dispatching loop or not.

>>57445728
>Engineers in particular are surprisingly vulnerable to this.
What the fuck? Where did you get this bullshit?

>>57445756
>The main distinction is wherever you are in control of the dispatching loop or not.
And that's why callbacks suck. Becuase the developer lost the main control.

Can we all talk about how great python is. I mean look how easy it is to write to a file:

>>57445810
>in an event system that is normally true, but not always
And that is why events are more flexible, because you can control the dispatching - which was my original argument.
Callbacks is you setting up functions to be called, then letting other code dispatch back to you, this is always less flexible than if you could do the dispatching yourself.

>>57445842
Tbqh as a C++ programmer I'm jelly of python just for this reason.
It's ridiculous that in 2016 it still takes 10 lines to read a file into a string in C++. And let's not even talk about the disaster that is Java streams.

>>57445842
in haskell this is just

writeFile "hi.txt" "Hey bud"

>>57445847
>And that is why events are more flexible
What the fuck? How the fuck do you draw this conclusion?

>>57445721
Well, your program isn't as portable as you think it is. Here, on FreeBSD, I don't sha512sum program, so I replaced it with sha512 and I don't use bash - only the native bourne shell.

#!/bin/sh
set -e
if [ -z "$1" ]; then
    echo "Usage: $0 FILE" >&2
    exit 1
fi
old_dir=`pwd`
cd "$(dirname "$1")"
f=$(basename "$1")
cp "$f" "$(sha512 -q "$f").${f##*.}"
cd "$old_dir"

You can enable debugging by tweaking shell's flags.

You can do that with callbacks, all you're arguing about is doing it yourself rather than having a framework.

Not as easily - and if the callback dispatcher is running in a dedicated thread you get tons of overhead trying to make it thread safe.

Well yes since the original post with Python was also writing to a file but reading with streams isn't that bad either.

That will only read one word though, and it will be extremely slow.

requests is part of the library's that come with python so I counted it as part of the language.

>>57445998
Because Python took a page from Perls book in terms of making a "naturally readable" language, and then told perl to fuck itself and proceeded to take a fat shit on all things performant.

Python is easy to use, don't get me wrong, but it's a trash language that should only seriously be used by researchers or scientists who don't have time to learn good programming habits and don't have time sensitive data execution.
Which is why so many of them do use python. It takes three hours to crunch this data instead of 15 minutes? Not like I care, that's fast compared to my experiments!

>>57445976
>Amateur. It's how you do it in C:

Also, Extended Slices are just sugar and not a real language feature imo.
If you want to talk real elegance, we will have to compare real programs.
This is where haskell shines, and python can't keep up with.

>>57446022
That's why python is meant for prototyping and not cpu intensive programs, you can whip up a program in an instant, test it, if it works, convert it to the language of you're choosing. Or you can use it for sockets or something which isn't cpu intensive and runs like a charm. That's why python is god.

>>57445979
Oh, I'm sorry, that was my particular habit of using sha256, I can replace it literally here with sha1 and it will work.
>There is no -q on sah1.
There is. All seven utilities for checksums on bsd have the same flags.
sha1sum from coreutils, on the other hand, doesn't have such a flag. https://linux.die.net/man/1/sha1sum Correction with respect to its clumsy output takes one like of code.

I mean my reverse shell works perfect in python and isn't slow at all. I am not saying python is the best at everything. But it is the best at what it is meant for.

>>57446060
good question.
I would say a real program is something we cannot discuss inside the scope of this thread.
And to understand the elegance of this real haskell program you would have first learn haskell for a year or two.
An example of what I think is good, would be miku
https://github.com/nfjinjing/miku
a webdsl, which is cute, tiny and seriously powerful.
You would have to understand Monad Transformers first to get it though.

>>57446078
You can write shit in it all you want, that's fine, it's easy to do if whitespace syntax doesnt bother you.
But it's not the best at anything other than being easy for non-programmers to use.

>>57446086
See above. Mathematicians aren't inherently handy with a programming language, and they're not exactly sitting around doing theoretical equations with a timer on the clock. There's no impetus for them to learn a faster language or one more suited to building applications.

If bash had the same package spread as Python they'd probably use that instead. It's a matter of convenience, not any form of superiority.

>>57446099
That's pretty cool. But there are also many real world python programs that many people use and aren't slow at all. One of my favorites is kazam

Granted, even though I feel right and justified, I still feel like the retard as this slight betterment (in performance, at least) is likely well-known but just dismissed for reasons I can't be arsed to look for.
Still, Retard FizzBuzz is some 25% faster than Standard FizzBuzz.

But the question then becomes why and how to remove this nuisance of speed being dependent on the order you run the loops.
The whole reason I was proud of the ugly code was that it only did two conditional tests per iteration rather than three or more, hopefully reducing number of operations hence increasing speed.
But alas...

Anyway, reading a stackoverflow question on this, what it looks like is that the virtual machine is automatically optimising the method as it runs. Which sounds bizarre to me.
I'll have to find out how to do call a precision clock in C++ to test it there.

>>57446369
Your ugly code might not be slower since your benchmark is biased anyway.

Have you tried using System.gc() after each loops?

>>57446379
To be honest, I've never heard of garbage collection, so no.
Currently grappling with C++'s high res clock. Every time I try to compile, I'm greeted with a wall of error messages.

I can't figure out how to fix my program. I have a while loop that takes a user input and adds it to a list, then in there, that loop is functions outside the loop that check the list for a condition. When condition is met it prints 'player won' but can't break out of the while loop.

    if counter % 2 == 0:
        new_state.insert(col, 'X')
        new_state.pop(col + 1)
    elif counter % 2 == 1:
        new_state.insert(col, 'O')
        new_state.pop(col + 1)

    for i in range(len(game)):
        print(game[i])
    
    vertical_win(game)
    diagonal_win(game)
    horizontal_win(game)
    counter += 1

>>57446585
do you mean that vertical_win, diagonal_win and horizontal_win have the break statements in them?

that won't work, what you have to do is return a boolean (true/false) from these functions and do

if vertical_win(game) or diagonal_win(game)_ or hoerizontal_win(game):
    break

>>57446585
So what's the problem?
Would the problem be solved with a tactical break?

>>57446553

>I'm very new to programming so I dont' know what that is

Right, with languages based in C, you get continue and break which you can stick in a loop to either skip a loop ("continue" the loop) or jump out of it ("break" the loop).
E.g:

for i in range(0,24):
    if(i==12):
        print("skip")
        continue
    elif(i==18):
        print("I'm out, bitches!")
        break
    else:
        print(i,", ",sep="")

Should demonstrate how they work.

> not sure the editor can decide what should be indented and not
It can't. It can determine when to increase indentation, but in most cases it can't determine where to decrease it (the main exceptions being "else", "except" or "finally" keywords which have to be at the same level as an "if" or "try", and "pass").

When checking if a number is inbetween a range is there a faster way than
num < a
do this
num > b
do this
num =< a && num => b
do this

I can just change the last check into an else right?

>>57447148
if (num < a) {}
else if (num > b) {}

At first, I was getting results strongly suggesting order-dependence with averages of:
Method 1: 57706.0
Method 2: 58206.3
Method 3: 57039.6

But then I dove down a rabbit-hole of stuff I never knew existed and the averages became:

It depends. It's more complicated than "switch is faster than if".

Working on my terminal emulator, fixed a couple tricky behavioral bugs and a plain crash.

One was a bug with how DECSC and DECRC were being handled, heatseeker (in the video after the fix) was doing a single DECSC and then multiple DECRC, and I assumed you could only restore once, so it would behave somewhat like a stack, but nope.

Another was a crasher when using Kakoune, after quitting the terminal would crash, for some reason it's sending a DECSTBM that ended up overflowing, so it's a bug in it but crashes are a bug in my terminal too.

don't you have to add that s to visited?

>>57448208
Pretty sure I don't for BFS.

Either way moving from std::vector to std::queue fixed the issue, so it probably has to do with the insertion order.

Why are you so good OP?

>>57445555
>>57445555
How do you prove someone with an opinion wrong? Especially on the supposition that what they've articulated is even cogent?

Programming languages can be verbose. The Developers Environment is bloated to abstractions pertaining to particular enterprise functions. If money needs a way to hide, it will make up many and any reason. Otherwise, the environment is formed over time and made to function for the particular company. But since most companies are treating CEOs like they're the latest polymer slammer in a game of pogs, then the whole idea behind a programming language functions like an argument between children. Words are thrown but only the emotion is prescient. And thus there is no argument but simply the bearer of an opinion that they did not form themselves.

>>57448093
where does the "adj" array come from?

Java:
I have a Swing window (Menu.java) which shows a main menu for a Pong game. This window has a button on it, and when it is pressed, it launches a JavaFX window (Lab4_5.java) which is the actual game. In the swing window, I also have text fields for player names and a spinner for ball speed.

I am doing all of this using model-view-controller design pattern, the problem is that the two windows use different instances of the Model class, which means that the text in the text fields in the main menu can't be used in the game (at least I haven't figured out a way to connect these two together).

How would you proceed? I've been at this for days and I'm out of ideas.

Pastebin:
Menu.java - http://pastebin.com/5E4Sufvm

>>57448744
Forget Java and start over in C. Also make the model class a singleton if that's what you're looking for.

>>57448744
Why aren't you using JavaFX for both windows?

>>57449063
Thanks for the tip, I'll look into it and see if that's what I want.

>>57449072
I didn't know how to make buttons, textfields and stuff programmatically in JavaFX at the time, so I fired up the good old swing drag-and-drop project. I realize now that I dun goofed, cuz it's not that hard. Thinking of rewriting the program.

>>57449141
yeah, you should rewrite the Swing part. I haven't used Java in a long time but JavaFx felt like a great improvement over Swing and Awt when I tried it out.

Please no political discussion, this is a genuine request:

Does anyone know where I can find raw data on the demographics and other voters stats in this election?

I'm able to find pre-made charts, but I'm having trouble finding raw tables to form my own charts.

I'm looking to include it in a small visualization application I'm making, to test some BI things.

Is Go worth of learning for back end stuff?

>>57449680

lol, fuck me.

>>57449411
I think there are too many programmers who focus on the specifics of a language. Syntax is very easy to learn in a language, and once you've learned a few languages and gotten a lot of experience under your belt, learning a new language is easy. Data Structures and algorithms are the important aspects of computer science. Focusing too much on the "right way" to learn C misses the point. You can micro optimize code in C all you want, but ultimately if you don't know good design or efficient algorithms or what data structures are used when then being a C expert means nothing.

>>57449682
I've found it a little lacking but a lot of the standard library, especially the net/http stuff, "just werks". It's also super easy to learn if you use gofmt (a linter) and have experience with C. It has pointers (pretty much) just like C, most of the syntax is similar but backwards... The only confusing thing about getting started is setting up all the environment variables and such. I'd say it's decent for hobby projects and maybe microservices but if I had to build a scalable OOP backend I'd go for .NET.

>>57449722
>Focusing too much on the "right way" to learn C misses the point.

I know how to programm. Programmed a shitton java. Just want to get behind all em concepts of C.

I'm making a python program that uses an API, and don't want to put my API key on github, so I'm learning config files.
Using configparser, is there a best practise for looking for existing config files in the standard places and creating one if none exist? Bonus points for platform-agnostic.

Where to I start if I want to create a simple graphics engine that will be able to demonstrate a single scene ? Curently I'm thinking that the end product will be able to demonstrate a scene like a single island that you can walk(first person camera) with maybe some trees here and there and a house model and sun to light the scene. The past days I have been messing arround with opengl,shader programming etc but I can't seem to figure out how it all connects together to reach my goal. Do you think that this http://gamedevgeek.com/tutorials/managing-game-states-in-c/ Is a good starting point in figuring it out ?

Hi /dpt/. Novice here. Is there something like a browser extension that I can use to get python to know what website a person is looking at? And maybe their mouse movement and scrolling?

>>57451166
that tutorial looks ok to start with but it seems to only deal with the logic and not rendering and input

to learn opengl i think it's best to browse https://www.opengl.org/wiki for a broad overview of the different concepts and then to read the actual opengl and glsl specifications (not the whole thing at once, just the part you're focusing on at the moment)

Is it true that most of programming is debugging and a lot of stress and frustration?

No, because game states are about multiple scenes.

>>57451222
>Not projectname.config

>>57451233
it sets up a rendering loop tho, he can use it with a single scene or with a menu, it should be really easy to figure out compared to learning opengl

or $HOME/.config/projectname/config

>>57451255
>it should be really easy to figure out compared to learning opengl
It's not going to get him any closer to what he wants.

>>57451264
he needs basically a game loop and that's what the code does (+ it has a stack of game states), he just has to fill in the blanks with rendering code

The game loop is the lowest hanging fruit and all the other stuff is just fluff and premature abstraction for his purposes.

>>57451288
how is this fluff and premature abstraction

#include "gameengine.h"
#include "introstate.h"

int main ( int argc, char *argv[] )
{
  CGameEngine game;

  // initialize the engine
  game.Init( "Engine Test v1.0" );

  // load the intro
  game.ChangeState( CIntroState::Instance() );

  // main loop
  while ( game.Running() )
  {
    game.HandleEvents();
    game.Update();
    game.Draw();
  }

  // cleanup the engine
  game.Cleanup();
  return 0;
}

it's not a lot of code and all of it is reasonable

>>57451303
Because that's not all the code? Why do you need a fucking class (CGameEngine) that will be instantiated exactly once and has the same lifetime as the main function? Put it in the fucking main function. The article itself and its recommendation is accomplishing nothing but introducing and/or reinforcing bad habits.

this way, each state can have its own main loop.
