why do japs like to sit on the floor on mats and thingss?
Every time I want to delete a node from a linked list. I pop the entire list to a buffer sequentially and then re-push it back in reverse minus one item.
How does that make you feel?
>>54275022
this is against the rules
>>54275022
ayy

you don't like sitting on the floor? what are you, some sort of faggot?

sorry I can't post the sound version outside of /gif/
post Lisp
OK, can someone explain Python license to me?
Maybe some idea about other Languages licenses as well?
I read recently some stuff that python is GPL and therefore to distribute your code written in python it must also be GPL so whoever buys your stuff has right to see the source code
Am I getting this right?
How are other languages licensed?
>>54275088
GPL is a literally a trojan virus invented by a communist. If you have no other choice, maybe allow LGPL, but not GPL.
>>54275049

i don't see how that could be true, imagine buying a pencil and the manufacturer having rights to whatever you wrote with it
>>54275088
but who was then
tried to find a ladygaga song, got this instead:

that's it
i'm making a fighting game
>>54275128
they discuss it here
https://www.reddit.com/r/Python/comments/4gpa83/employer_refuses_to_allow_python/
I dont feel like theres clear cut answer in the discussion there, but there seems to be common theme that there are limitations when you go in to distribution of your code
>>54275172
>clear cut answer in the discussion
that's fucking reddit for you, they talk all day but they can't answer shit, at times i have to filter reddit out when searching, cause google keeps thinking that they are reliable sources for answers
nah, as i said, that would be fucking retarded and i'm sure you can quickly find closed source python programs out there.
>>54275128
That is literally what GPL is.
Someone gives you a pencil, then turns around and says the Mona Lisa -tier drawing you made must be open source too
>>54275153
why not be creative, original, and actually make something different and something people might actually use?
>>54275153
fighting games are the hardest kind of game to make t b h lad
I hope you have some experience in gamedev already
>>54275222
Really?
Anon on 4chan where even in programming thread on /g/ pedophiles need to bicker over their favorite anime 6 years old girl... is going high-horse on reddit?
>>54275225
yeah but i doubt python is that manufacturer
>>54275257
no, they're the hardest to balance, anon there will probably make a shitty version of an existing fighting game nobody will ever play
>>54275249

I legit do somerhing like this in java. I make an array and when in need to delete an item i just delete the array and remake it with the same elements minus that one. Anyone have a better solution, cause mine feels retarded as shit.
using Java 1.7
want user to input string
then program will assign ints to the chars as well as whether the char was a vowel vs consonant
then do some math on the int values based on the individual chars entered
should i use array, arraylist, hashmap, other?
>>54275288
Can someone explain it to me
SFML uses multiple libraries that are licensed under GPL, yet it uses some custom MIT-esque license.
My website uses psycopg2 as the database driver, which its LGPL. Does that force me to use LGPL/GPL? What if my code just imports psycopg2?
>>54275369
If you have to compact the array, just memmove to overlap the item you want to delete and realloc.
>>54275011
>r/ReverseEngineering
Can /g/ into reversing network protocols? I've been entertaining the idea of writing a bot for a shitty mobile game my friends play. How would one go about doing this?
>>54275369
i think i just remove the item without redoing the array
>>54275317
Go away.
>>54275412
I dont think that's possible in java?
>>54275411
start by sniffing the network traffic, the chances are a shitty mobile game uses plaintext JSON/XML/other crap so it will be trivial to work with
>>54275399
Also to add to this, SQLAlchemy is MIT, but it depends on psycopg2
Am I supposed to recursively look through every fucking library that I use to see if any of the dependencies use some shithouse license like GPL?
>>54275410
>shrinking the memory
I seriously hope you guys aren't this retarded
>>54275428
dunno about java
>>54275411
use something like wireshark
also this: >>54275433 especially for the shittier mobile games, like with flappy bird you could just edit the high score in plain text
>>54275410
Yeah that sounds good. Imma go figure out how to do that in java.
>>54275433
>>54275455
couldn't he monitor the memory and see what matches ingame, like cheatengine?
Sup /g/ newfag c++ fag here.
I'm trying to program a store kisok for my final project, and I had a few questions.
My basic idea is to have one main source file, with other c++ files to imitate stuff like a printer for recipes and an inventory system to check whether the entered barcode is valid, and the display the actual food item. Do those files need to be .h files? Thanks in advance lads.
>>54275478
if it's online he needs to affect the server, like send commands as if he's playing the game
>>54275478
how's that gonna help? he needs to manipulate network packets, sure he could use cheatengine to figure out the packet structure and hook into the socket to intercept read/write ops but why not just analyze the traffic first?
>>54275290
>>54275222
yeah, discussions on /dpt/ are much better, amiright ?
Quick question.
My Python 3 script:print(wait, "hours from", hours, ":00 it will be", time, ":00")[code/]
Prints:24 hours from 12 :00 it will be 12 :00
[code/]
How do I get rid of the spaces between 12 and :00?
>>54275257
? Literally the simplest of games. a 2D landscape with parallax scrolling, a bunch of animating textures that correspond 1:1 to a hitbox state machine. The underlying crap is literally a solved problem and the hardest thing is balancing the craploads of characters which should be doable with a good dose of game theory.
>>54275501

>>54275455
Game in question is Empire Z.
I'm not exactly a whiz at networking and I'm sure how to use a software to sniff just the game's traffic.
What I did was decompile the APK. Seems to be some kind of shitty obfuscated java code that calls an ARMv7 shared object, which is likely where the game and net I/O stuff actually is. I have an exam in some hours so I haven't gotten to it yet, but I'll bust out the Hex Rays for this thing and see what I can figure out.
Ask your much beloved programming literate anything (IAMA)
>>54275544
You can set a customized separator through the named argument sep
eg:
print("a", "b", sep = "")

I found the cs related subreddits to be quite good.
>>54275577

>>54275607
If you don't use templates in virtually everything you should be shot
>>54275639
look for java.net and android.net packages in the java code, otherwise it might be in the shared object
>>54275577
it's beautiful
>>54275501
Yeah, the idea is to create my own scriptable game client. Then I'll write an AI which will automatically collect resources and develop the character. Forever. Then I'll run like 2k instances of them and zerg rush the pay2win top tier faggots with hordes of anonymous no-name accounts they can't track because they don't belong to any in-game group (alliances).
Trolling to the max
>>54275597
Considering "good fighting games" are created almost by accident and pretty much never on purpose, I'd say there's really no difference between those two categories. It's a combinatorics problem so huge, it just happens to work out in practice somehow.
>>54275670
how does using templates relate to using cpp files?
>windows has UNC \\?\ paths which send the full pathname directly to the FS

That wasn't the point. You were objecting to using cpp files. You should use them alongside headers for declaring member functions.
>>54275905
I'm honestly so sorry but you really aren't funny. Nothing you've said has been funny and you are lowering the quality of this website. It's not your fault, every under age redditor is like this. That's one of the many reasons the age limit is in place, and why reddit is hated so much
So is GNU Make like the LISP of build systems or what?
Shit's literally a functional programming language. You can metaprogram it to do the most crazy shit.
I think I hate Make a little less than I used to now.
>>54275937
That is exactly the point.
If almost every class is templated, you should barely have any cpp files.

The only excuse for avoiding templates is using void pointers
Templates allow you to reduce the binding between your files, regularly lower the number of #includes, produce consistent, reusable and modular code, etc.
>>54275984
templates is the greatest thing offered by C++, they are a true advance in the programming language theory field.

>>54276041
he's right, you don;t need anymore to declare data structures for every types.
>>54276073
You should be using intrusive data structures anyway. They're analogous to how template metaprogramming works and in plain C.
>>54276073

Please don't.
Just use it as an install and build script, there's no need to run 50 shell commands just because you want make to automate every last thing.

SFML dependencies:
PThreads, OpenGL -- License depends on implementation, generally not GPL.
Xlib -- Uses its own license, I think.
Xcb, x11-xcb, xcb-randr, xcb-image -- MIT, I believe.
Xrandr -- Custom license. Not GPL.
Udev -- LGPL
Freetype -- Two licenses. One is a BSD-like license that is compatible with the GPLv3 but not GPLv2 (Apache is like this as well), one is GPLv2. Either is acceptable.
Libjpeg -- Custom BSD-like license.
OpenAL -- LGPL
libFLAC -- Xiph.Org BSD-like license.
libVorbis -- Xiph.Org BSD-like license.
And no, you don't need to GPL or LGPL your project if you use an LGPL library. The LGPL only requires that any changes to the LGPL library itself be re-contributed. The library you link it against can be whatever fucking license you want.

I clearly need mileage, but if I pick up a project that actually lets me focus on designing solutions, then I'm not learning anything, and if I have to spend two weeks googling unreadable error messages before can even I start, I'll sooner hang myself. What's the middle road?
The worst part is the feeling I'm not even moving ahead. Half the time I don't even get what fixed it and the other half's useless anyway, because the next technicality is something different again.
Should I just focus on less frustrating languages? Is C++ even particularly annoying or is it all me? Honestly, I've only ever worked on tiny projects in anything else. I have no idea what field I'm even going for.

Programming algorithms, datastructures and languages isn't a cutting age CS research anymore. Cutting age research is Machine Learning, it doesn't matter which language you write your ML in, if it works and it is fast.

only people who hate it are pajeets upset about it being a better designed language than java. I don't think anybody else even cares about c# here with some rare exceptions who just think it's alright.

}
}
>>54277118
only people who like it are pajeets that believe c# differs enough from java for java to be shit tier and c# to be top tier
irrational hate for java & irrational love for c#
Speaking of C#, how well is it supported on non-Windows platforms?
Do you still have to use Mono to get a non-trivial C# application to run on Linux?
I heard something a while back about MS releasing parts of their .NET runtime as open source. Did that improve C# working on Linux?
What I'm trying to ask is, how good is C# on Linux? If I make two similar GUI-based programs, one with Java and Swing and the other with C# and its own GUI library, will the Java one perform better on Linux, or is C# on Linux also pretty capable?
I am asking because I have read a LOT of good things about C#, but I cannot justify spending the time to learn it if I can't run a C# program well on Linux.

You shouldn't have problems with ordinary programming, shouldn't fear highschool math. ML builds on these skills.

>Do you still have to use Mono to get a non-trivial C# application to run on Linux?
yes
>Did that improve C# working on Linux?
It's still in development. They are transitioning from one set of console tools to another, there are only packages for a few specific version of linux distros depending on specific library versions, so basically you can get .Net core working without issues as long as you stick to the same (outdated) build environment as in step-by-steps
>how good is C# on Linux?
Mono is ok. Java fares better performance-wise and obviously has better infrastructure for linux development. .Net core (console only so far) and the latest asp.net are supposed to be faster. Plus there is ahead of time compilation support (and llvm backend) in development. But this all is gonna be ready for straightforward use in some unforeseen future.
Basically if you want to learn the language by writing mostly GUI desktop software - it's Mono only. If console apps + web apps in Asp.Net is fine for you and you don't mind either using ubuntu 14.04 or spending time figuring out how to build .net core from source on a different system, making it support newer dependencies (which isn't really the greatest start to familiarizing yourself with the language) then do that.
Where it's worth or not to learn it - idk, it very much depends on whether .net core is going to be at all successful

I use ASP.NET Web Api at work sometimes.
When I saw that you could use it with OS X and Linux I gave it a try, it is a super shitty experience. It definitely isn't anywhere near production ready.

As far as C# goes it really is a very good language, but it's not really production ready for multi platform.

subtract the current iteration from the user input, write half that many ones, then write zeroes number of zeroes, then write half that many ones again. New line, add two to zeroes, one to iteration.
Do this while iteration is less than half of the userinput. Then write a line of zeroes. Then just do the top bit in reverse.

>how much code do we need to draw a single pixel
Well, first off, SFML isn't one library, it's several. Things like FLAC, Vorbis, and OpenAL only really apply to the audio library obviously. Windowing needs to interface with whatever is native on the given operating system, which on Unix platforms is typically X11. So all of that Xlib/Xcb crap is just "make a Window within which to draw a pixel". You don't really need Libfreetype or Libjpeg to draw a pixel, but you do if you want to blit text or images to the screen. Pthreads is obviously for SFML's threading library, which is optional, but I think used also as part of the audio library (because audio should be handled in a separate thread, naturally).
So I guess... OpenGL is the only thing associated with just drawing pixels. But you wouldn't use SFML just to draw a pixel. You'd use it for creating a complete 2D game, which you'll probably want most of its features in.

If you want awful, consider that it allows string literals, but doesn't allow a string type. So you can write strings using the built in procedure write, but you can't manipulate them. You also can't read strings -- just integers. It's not exactly a fun language, but it's designed to be easy to compile for. Also, we have to target the professor's virtual machine he calls hc -- Hypothetical Computer.
This professor always gives fun assignments, but they're always a little bit limited, since we're always working on 10 week quarters.

you're a fucking idiot dude you're literally the only one i've heard of that uses auto wrap for programming
what kind of shit code are you writing that needs line wrapping anyway

sure, but scrolling isn't so hard either. Wrapping can make the code hard to read by wrecking the indentation. Indentation exists for a reason. And word wrap is almost always off for a reason.
>>54278721
who the fuck is this newtrip
>>54278665
you can use 120-160 chars and you can manually wrap the line with double indent
and your OOP is not as good as you think it is
fuckface

>doing such bullshit instead of turning on text editor feature and using a non-meme language
>>54278775
all non meme languages use indenting anon.

KILL YOURSELF SMUG PRICK LITERALLY >99.99% OF THE PROGRAMMING INDUSTRY DON'T USE AUTO LINE WRAPPING I SWEAR YOU FUCKING SHITTER
>>54278782
yes, but they dont need to overdo it becsusr of wordwrp option. with wordwrp they get wraped words without need to do much work. your teammates maybe not as smart as you so they make long line, annoying a ufkc tos croll throug it. so instead, you turn on wordwrp and it is readable easily
understands?? wordwrap is life in non-meme languages
>>54278800even 4chan doesn't use it.
>>54278823
you're terrible

Then why is it off by default in every popular IDE and text editor for those languages?
>>54278864
sublime on by default
emacs on by default
visualstudio last time i used it
idk
>>54278926
>sublime on by default
eh.. no
>visualstudio last time i used it
not as long as I've used it. Over 10 years now.
>idk
So it would seem
>>54278926
no fucking way

>private String firstName = null;
>private String lastName = null;

why?
