Anyone have experience with GPU programming on EC2 instances? I installed tensorflow onto one but the second I try to utilize the GPU it freezes and the process needs to be killed.
Is there just a super long wait time for the GPUs or what?

>>54237032
I don't think they have a GPU, unless you order the workstation instances, that do.

>>54241631
An array is used to store a collection of data, but often we find it more useful to think of an
array as a collection of variables of the same type. Instead of declaring individual variables,
such as
number0
,
number1
, . . . , and
number99
, you declare one array variable such as
numbers
and use
numbers[0]
,
numbers[1]
, . . . , and
numbers[99]
to represent indi-
vidual variables.
>>54241631
it would be much easier with the normal for loop which python doesn't havefor(int i = start; i < end; ++i)
i is an index into the array

It applies a function to every element of iterable container, so it basically calls setup(index, artist) on each element in the result of enumerate(artists).

>a) can I deploy the project with the prepared assets?
Are they downloadable from the original release? If so just direct your users to download it from there and put in the game folder. Also worth looking into the license.

The assignment is to make a program that counts words/lines/symbols in a text file or a stdinput (when no text file is given).
-l is to count lines, -m is to count symbols. no option given = count words

'program.exe [file]' counts words from a file
'program.exe -m' counts symbols in stdinput

I never cared for Sublime.
I used Notepad++ for Windows work, and now have standardized on Atom because I can run the same IDE on Windows, Linux, and Chrome OS and have it automatically sync the packages and configuration.
When Atom can't handle it, I reach for Eclipse.
>>54242794
He's right though. Generally speaking you should strive to make your code readable enough to not need comments, and only comment stuff that really needs it.
>>54242717
in the days before cellphones, was broke and hungry once. i called and ordered myself a huge pizza and drinks and desserts and sides (about $60)
>write note and tape to door:
"sorry, had an emergency. had to go pick up family member. called store and paid via credit card, including $5 tip. please leave food on porch. thanks!"
turn off all lights and be quiet as fuck
>knock knock
>shuffle shuffle
>car starts and drives off
yum!!!
>>54242812

Any tips on recursively traversing a general tree that uses vectors to hold node pointers?
>>54242845
What kind of productivity applications do you make?
>>54242880tree.traverse();
>>54242880
the normal method would be either breadth first or depth first, both functions flatten a tree into a sequence
>>54242850
For that much they would probably have the brains to call the store and check
I'm not saying it's a bullshit story... but....

>>54242967
No, I meant are they productivity like for learning stuff or time management?
C/C++ HOMEWORK ASSIGNMENT
Consider a node with pointers to two "subnodes":
struct node {
node *a, *b;
}
Write a function that swaps the subnodes of a node passed to it, without calling any functions.
97% will fail this
something to think about:
>not asking if it would be a good idea or not.
but would it be possible make a small pc (like pi-ish) that ran java natively?
write java code> run directly on the hardware. no vm. and would java translate to the binary or is bytecode the most primitive it could get?

Anon, writing and calling a function are not the same thing
only pajeets comment everything

What?
Do you understand how native code works on a computer?
>>54243098
aren't you thinking of a pc that runs (er, um... ran) Sun OS? aka SunBox
>>54243279
Native code doesn't exist on the magical Java Virtual Machine

>>54243171
What were which about? The mobile app was for a company i worked for. They have a project management web app thing they sell and I worked on the mobile app for it.
>>54243333
What does the project management app do? What does the desktop productivity application do?
>>54241620
Almost all games have dependencies.
>>54243103
Okay, I just meant that the function you write must not contain any function calls. So you have to swap the nodes by hand.
An imageviewer that supports all image formats (including webm) commonly found on imageboards and allows the same comfiness that I was used to when using HoneyView.
Python + PySide (Qt4) currently. Might switch to PySide2 once it's released, although that doesn't matter much -- maybe for the nicer Phonon backend.
Picture related. I did something similar before, so I can reuse quite a few parts of the code, but I want to do it properly this time around.
Suggestions for a better name are always welcome.
>>54243317
>Native code doesn't exist on the magical Java Virtual Machine
You realized that JIT is literally translating bytecode into native code, right?
>>54243370
That doesn't answer my question at all.
>>54242845
No he isn't, and he'd get shit canned from any development shop with competent management.
Poor commenting is literally the easiest way to get fired from a development position, outside of rampant absenteeism or outright theft of company property.

>>54243384

>>54243348
the project management app was like basecamp pretty much. Not gonna say what the desktop one is because there's too few of them out there. It would give away what it is.
>>54243438
But he's recommending good commenting, not poor commenting.
>>54243317
Right... When you say "physical compiler", what the fuck are you talking about? Do you mean a native compiler like in C?
>>54243279
A better idea would be a metaphysical java compiler. The resulting program wouldn't even require hardware to run.

Hello friends.
Just started to learn python, my first programming language.
I'm stumped on project Euler problem 3 as per the image attached.
I don't want a direct answer, but perhaps one of you could point me in the right direction with how to get started.
Thanks.
The name of a topic/technique will do. I want to figure it out but I need a little push.
What are libraries?
What's the opposite instruction of JE?
>>54243710
It's like a building with books and shit inside.
>>54243679
Get an algorithm that checks for primes, and evaluate a modulo that equates to 0, print when both conditions are true. Start from half+1 of the big number and count down. What ever prints first is the answer.
>>54243710
>>54243733
It's like a folder with headers and shit inside.
>>54243735
Thanks senpai.
I was thinking along the same lines actually. I just have no idea how to check for primes in an efficient manner that doesn't involve churning shit loads of numbers.
I'll figure something out for that part.
>>54243764
No one does, that why primes are a cornerstone of encryption. AKS and Miller Rabin are good though.
Does anyone know the colour code for the JFrame?
I usually organize my projects by which language they're written in, e.g. cpp/profiler is the folder which holds the profiler program source written in C++. But often, some projects rely on multiple languages, and I sometime want to see projects by their name rather than language. Yet, the programming language used matters because of the corresponding toolsets and to know what toolchain needs to be installed when moving.
Why are non-retarded tagging filesystems not a thing yet?
That's a good idea for a project I guess.
>>54243793
Wow. OK no wonder I'm stumped then.
Cool, thanks, I guess I'll write something that just churns numbers or copy something you've mentioned.
>>54243468
I see about the project management one. It is a shame you don't want to say the desktop one you have nothing to worry about from the people here on ./dpt/ they can't even do FizzBuzz properly

Is it true that most people who program (probably excluding most people here) can't FizzBuzz?

>>54243873

What Universities do you attend??
Java question.
I have a list of <AbstractProduct> which contains objects of 5 different subclasses of AbstractProduct.
Now I need to access methods of these subclasses on the objects, which means casting.
I'm kind of hesistant to casting because this typically reeks of bad design.
What does /g/ think? Is casting always bad? Is there a way around?
>>54244066
A good one, which is weird.
>>54244059
Maybe. Sell us on the game idea.
>>54243735
>Start from half+1
Ho ho ho.
Can you explain why floor(sqrt(value)) is a better choice?
>>54244071
Generally there's a better way of structuring the code to avoid casting.
What is "AbstractProduct" exactly, and why do you need to access certain methods on the subclasses?
>>54244071
Why don't you define abstract methods in AbstractProduct and use polymorphism?
>>54244080
the theme is horror and we're planning to release within 6 months or so. we're in the brainstorming phase and we're just coming up with ideas on what to include so we could use any sort of inputs on it especially from a programming standpoint

Saying that the "theme is horror" isn't going to sell anyone. There are plenty of horror games. What ideas make your game unique and fresh?
>>54244118
>especially from a programming standpoint

>>54244163
True the only reason I got into programming was I wanted to make a video game but once I realized it's way too hard and only really intelligent people who have been programming for 10+ years can do it I lost all interest in programming
>>54244134
no they're not
>>54244141
there's no code yet. we're building this from the ground up. essentially we're looking for people that want to be part of every stage of the project
>>54244178
>no they're not
You don't think children should play games? You are a monster.
>>54244198
No one should play games they are a waste of time
>>54244177
Not true now. There's UE4 and shit. Unfortunately to do that you have to be good at photoshop and whatever autodesk is shilling nowadays.
>>54244178

>there's no code yet.
>we're building this from the ground up
>6 months
>>54244212
UE4 is not easy to learn it requires a ton of work and so many hours learning and then many more hours learning to do art properly
>>54244170
that's where we would collaborate on things like game mechanics, unique characters, storyline plot details etc. again, this would be a team thing where the project belongs to each member
>>54244173
doing that sort of thing wouldn't be within the best interests of the project. we just want to collaborate and create something cool that can be shared and hopefully also be a learning experience

People are extremely incompetent and lazy. This surprises you? Most people get nothing out of being virtuous and only enjoy satiating their baser instincts. I know you spend 16 hrs/day on the computer, but come on.
>>54244259
How many are you? What experience do you have with game dev etc.?
>>54244266
Post your UE4 game ohh right you don't have one because I am right
>>54244261
They are a waste of time they won't help you be productive like reading a good book
>>54244104
I do that already for the most part, but there are attributes which are specific to the subclass, like this:public abstract class AbstractProdcut {
abstract double getPrice(); // this function is applicable to all types
}
public abstract class AbstractProdcutType1 extends AbstractProduct {
abstract double getNotional(); // this function is not applicable to type 2
}
public abstract class AbstractAnotherType2 extends AbstractProduct {
abstract double getMaturity(); // this function is not applicable to type 1
}
I have a List<AbstractProduct>, and depending on the type I need to do different things.
>>54244093
>Generally there's a better way of structuring the code to avoid casting.
I only have that list of type AbstractProduct, putting them in different lists from the start isn't an option.
>>54244285
>reading a good book
>productive
you can't make this stuff up
>>54244308
nvm i misread it
but especially for gamedev it obviously helps to have played games yourself for fuck's sake
>>54244308
reading a good book is much more productive and will help you grow as a person or learning a new language. Not video games though. Exercise is also productive.
>>54244282
the other guy is an artist who uses unity. i know java/libgdx. i've developed simple games before alone but nothing on a larger scale. we're not even planning for this shit to be a large project or anything but more like a side project
>>54244297
>putting them in different lists from the start isn't an option.
I'm not suggesting that.
What would you be doing to them in a loop that would require casting?
>>54244343
reading a "good book" is just as masturbatory as playing games if not more. games are interactive and help develop visuospatial thinking and fine motor skills and also >>54244326
>>54244228
>shitters
nice tumblr meme
>>54244366
If you spent all the amount of time and effort you do into playing video games reading books you will become way more intelligent, well cultured, and more interesting of a person to build your character. This is much more important than just playing a game which will waste your time.
>>54244408
sorry but you clearly don't appear as a prime example of the things you claim. programming isn't for you, maybe you should become a writer or something.
>>54244408
who's talking about playing games though? because developing games and playing them are very different
>>54241538
I haven't touched Python in ages, but those m[1-9] and r[1-9] could just be arrays initialized in a loop. Like this:move = //however the fuck you declare an array in Python
//impyling a scripted language even has stack allocation for arrays
for m in move
m = [random.randrange(40,60) for x in range(10)]
So first you declare an array and then for each of its index you assign it a value from a function. Repeat for the other array.
And that's pseudocode, I really have no idea how to write this in Python.
>>54244082
How is it a better choice? The greatest prime factor could be greater than the square root of the big number.
>>54244358

No. People who program can fizzbuzz.

Once you get past the sqrt all the possible divisors just flip. There is no reason to continue checking divisors past the sqrt
Consider the number 16
1 x 16

Once you get to 4 x 4 all the other divisors are the same, just flipped.
