Why are you guys not using visual basic????
>>53796785
It feels really ugly to code in.
>>53796831
Visual studio has a really nice ui imo. I've used tons of programs and Visual Studio is so far my favorite.
>>53796767
comfy perhaps. But when you actually want to get shit done, there's far better alternatives.
>>53796884
If you're using Visual Studio you might as well just write C#.
>>53796884
No no, not the IDE. The language itself. I was forced to use Visual Basic .NET and the Entity Component Framework? for a summerjob, writing a GUI interface for managing some parts for a production line. It just felt really bad/unnatural -- the syntax of the language that is. I quite disliked it, after having written Python etc. for a long time. It didn't even go away after a few weeks, so me getting used to it wasn't the problem either.
>>53796917
A lot of it looks like pseudo code honestly just type do this and it will actually do it.
>>53796886
I do get shit done really quickly with Python. I suppose it depends on the use-case. Could you name an example where you yourself wanted to "get shit done" and clearly Python wasn't the right choice?
For CPU intensive tasks, yes, Python is not the best choice, but what are you talking about exactly if not about such a scenario?

Literally everything.
A simple script for renaming files? F# is better
A large complex game or application? Again F#
>>53796975
c/c++
literally any non-scripting language
>>53796977
I disagree completely, but to each their own. You just don't like Python for other reasons and conclude that it clearly must be worse then than your favorite other language X. That's fine, but not really based on fact.
Renaming a file in Python is literallyimport os
os.rename('a', 'b')
Not sure how much quicker/easier you could make this.
Or:for root, dirs, files in os.walk(path):.
# do something here
pass
>>53796996
That's dumb. For non-CPU-intensive tasks C/C++ clearly aren't better or quicker. This is just shallow trolling and quite dumb to read.
>>53797020
>pass
That's where python designers failed.
This isn't exactly a programming question.
I saw this on a machine walking through an arcade the other day, and I was wondering what it means exactly.
Some assembly instruction tried to access invalid memory?
>>53797068
Ahhhh yes, let me just crack open my sdaemon.exe error code reference book...
>>53797040
tbf I'm not sure why he included pass, it isn't necessary.
>>53797068
>instruction tried to access invalid memory
yep, that's the proximate cause
>>53797084
I guess I should have asked if there is enough information in that prompt for us to really know what's going on, or if it all depends on the application.
>>53796488
Because I'm disgusted by everything and everyone.
>>53797068
>invalid memory?
The memory doesn't have to be invalid per se. The process might not have permission to read from that memory address, for example.
>>53797068
My guess would be someone tried using a pointer to a certain spot in the heap that was already in use.
>>53797068
The program tried to access address 0x18 which was probably outside the range of the assigned virtual addresses, and segfaulted.
>>53797093
It is.def donothing ():
def dosomething ():
print 'foo'
That code ain't valid. It should, but it isn't.
>>53797093
It is. Try to run that code without pass. pass is a result of structuring code with indentation -- it's needed when you have a control-structure that ends with a colon and would have an empty line below it elsewise. The comment doesn't count.
It's not really a design-flaw, but I couldn't be bothered to explain it.
>>53797112
>referenced memory @ 0x18
something tells me it might be indeed trying to access an invalid region
>>53797068
I honestly always wondered why these error messages phrase it like
>The memory could not be "read"
I mean, why the quotation marks? It's like it's making fun of the term reading when it comes to memory.
>>53797121
>>53797125
I assumed that the comment would be replaced by statements.
I wanna make an app that suggests formula amounts for bottle feeding for babies by age and weight. I have an idea of the code I'd have to write. I suppose I can do a bunch of if/else arguments for the age/weight but would I need to store the suggested amounts in an array to be logged after the age/weight is processed? It'd probably all be strings, but videos would be cool too. Is it okay for arrays to be a bunch of strings? And can you store videos into an array?
>>53797020
>You just don't like Python for other reasons and conclude that it clearly must be worse then than your favorite other language X
That's a huge presumption on your part. You seem to have come to this conclusion without any basis on fact without a hint of irony. Nice job.open System.IO
for fileName in Directory.GetFiles(path) do
File.Move(fileName, fileName + "shit")
It also happens to be statically typed, and faster. And i can use it as part of much more sophisticated applications that python is not suited for.
>>53797167
Ah yes, then pass isn't needed -- you are right. That's why complaining about pass:
>>53797121
Is dumb. You probably won't use it in your Python script, and I guarantee you, you won't see it more than a few times even in huge code-bases -- unless they use Mixin classes really heavily or something.
>>53797188
What do you mean videos?
>LDAP goes poof
>"Why do we use active directories? the Jira connecter isn't working"
Ah, so that's why middle managers hate programmers.
>>53797120
Remember that the prompt says "referenced" memory and not "dereferenced" so that's what is throwing me off.
>>53797221
Short demonstrative videos of me preparing the bottle with the specified amount of formula/water.

It's longer. And "faster" really? Do you really think the bottleneck of renaming files on your HDD/SSD is the CPU? Goddamit man.
And yes, that's the conclusion I came to because nothing else made sense; but you really told me, bro. Awesome.
> And i can use it as part of much more sophisticated applications that python is not suited for.
For example? Specifically not CPU-intensive applications, as I have mentioned that I'd agree with you on that point, however what sophisticated application isn't Python suited for? Consider that the original BitTorrent client was implemented in Python for example.
>>53797250
Was for >>53797202
>>53797244
It is most likely using "referenced" in the informal sense, as in the instruction tried to "look at" memory in 0x18.
The word "dereference" is generally used in terms of pointers, but "reference" doesn't have a specific meaning like that.
>>53797250
ok. I don't see why you would, but sure.
>>53797281
Future functions that will be implemented but aren't.
>>53797292
Sure alright. In that case pass makes sense, but it usually isn't part of actually developed projects, and usually it wouldn't even make it into the repo I assume.
>>53797260
>It's longer.
it's not
>And "faster" really?
yes
>Do you really think the bottleneck of renaming files on your HDD/SSD is the CPU?
no.
>that's the conclusion I came to because nothing else made sense
Perhaps then you should be more aware of what you don't know then. Next time someone tells you they know a language that's better than python, instead of assuming the must be wrong, ask them why.
>Specifically not CPU-intensive applications
I mean CPU-instensive applications, I know you agree with me, it's still useful. I also mean complex large programs, to which dynamic typing is utterly unsuited for.
>Consider that the original BitTorrent client was implemented in Python for example.
And Facebook was written in PHP.
>>53797248
You'd be better off storing links to the videos in an array rather than like storing the actual video content in an array. Just pick the right index, get the link and open the video with the systems default video player, or have them on youtube as private videos and open them in a new window or embed them in your app.

Or if you want to use Powershell from within C# for some hacky reasonPowerShell.Create().AddScript("rni a.txt b.txt").Invoke();
Why would you use Python or F# for this?
>>53797319
It is longer. Just count the characters. I put faster in quotation marks because it doesn't matter in this use-cases, and the use-cases I described from the very beginning -- tasks that are not bound by CPU. So it's completely irrelevant.
> Next time someone tells you they know a language that's better than python, instead of assuming the must be wrong, ask them why.
Why? I am finding that out through this discussion -- are you really complaining about the way I lead this discussion with you?
> I know you agree with me, it's still useful. I also mean complex large programs, to which dynamic typing is utterly unsuited for.
Good that we are on the same page about one thing then. Clearly Python is suited for complex large programs, if you consider that many of Google's flagship projects are written entirely or for the most part in Python, the original BitTorrent client is (as mentioned) and Django web applications have a very complex code-base under the "surface code".
> And Facebook was written in PHP.
Yes, your point being? That PHP can also be used to write complex applications? That's not really proving that Python is unsuited for that task.

I didn't call Visual Studio useless, because I personally love it. Did you reply to the wrong post? All I'm saying is that I'd take C# over Visual Basic any fucking day of the week.

Bullshit. Google is a C++/Java/JS shop. ANd they've been working like fuck ver the past decade to add static typing to JavaScript. First with GWT, then with Dart and now they've even partnered with Microsoft to use TypeScript. They do this because they know dynamic typing is shit for large code bases, like everyone knows.
I'm not saying JS, Python or PHP can't be used large programs. I'm saying they are not suited for them. The fact that some large projects used any of those does not change that.

======================================================
Towards Machine Intelligence
Kamil Rocki
IBM Research, San Jose, CA 95120, USA
Abstract.
There exists a theory of a single general-purpose learning al-
gorithm which could explain the principles of its operation. This theory
assumes that the brain has some initial rough architecture, a small li-
brary of simple innate circuits which are prewired at birth and proposes
that all signi cant mental algorithms can be learned. Given current un-
derstanding and observations, this paper reviews and lists the ingredients
of such an algorithm from both architectural and functional perspectives.
======================================================
FBs paper http://arxiv.org/abs/1511.08130 was better imho
>>53797560
>So you deny that Google is using Python?
I didn't say that at all. I'm sure they use a small bit of lots of langugaes, but python is certain not in widespread use. Probably get's used by researchers.
>unless GetFiles actually returns the full, absolute paths to each file?
it does.
they are pretty much the same, except some of the words in F# are longer. It's not any harder to read. It's also statically typed.
>>53797594
Nah I use Vim as well.

(I'm about to read the original Stallman emacs paper, maybe I'll get it. Evil was sluggy when I last tried it)

2) Some production code is probably written in python too

print("older than 10")
}
if "Bob,23" as Person {
print("older than 10")
}
>>53797675
My point exactly. It's only used by researches because it's popular in the research community. It's often the only language they know. I'm sure a bit have leaked into products as a results, but actual programmer know better than to use that shit.
>>53797615
Sure, great argument. Every company that serves to prove a point you disagree with is "piss" and only an advertisement -- you see where this doesn't help prove your point, right?
>>53797645
You are right, you didn't. Still, I was under the assumption that things like the YouTube code base and many other projects etc. are largely Python. Of course the actual CPU stuff probably isn't, or just Python bindings. I have read this countless times, so I'm pretty sure it's correct.
Yes it's statically typed, and I'm sure that's a huge advantage from your point of view, but it's negligible to me personally. I also think it's possible to manage and write complex code with Python, as is proven by the existence of huge projects written in Python; I can't put this any more clearly.
> Python is not in widespread use
That's completely incorrect, it's hugely popular and is only becoming more popular. I think it topped various popularity lists for programming languages.
>>53797703
For example its very probable that AlphaGo used Tensorflow, so python (though deepmind is known to use torch/lua, so it may be torch).
>>53797675
>1) All researchers use python
and they used perl before that, not an exactly an glowing recommendation
>>53797703
>>53797716
But you seem very sure in your opinion, so I will stop discussing this point now. I hope at some point you might discover some interest for Python, but it really isn't "shit" or as disadvantaged as you think.
>>53797753
> you might discover some interest for Python
I'd rather barricade my indoors bathroom and learn java thanks.
>>53797716
>Still, I was under the assumption that things like the YouTube code base and many other projects etc. are largely Python
I recall youtube is mostly C, not even C++.
>but it's negligible to me personally.
It makes code work faster by catching wide classes of bugs at compile time. Your code is much more likely to run correctly the first time in F#, and you tend to have much more confidence in it being correct generally.
>I also think it's possible to manage and write complex code with Python, as is proven by the existence of huge projects written in Python; I can't put this any more clearly.
I completely agree. Anything is possible in Python, except performance related stuff. But just because it's possible doesn't mean you wouldn't have it done much much faster in a different language. There's a reason large projects are very rarely written in python.
> Python is not in widespread use

I used python many times over the years. It's nice in some ways, but it's not good for getting shit done. I'll happily use it for a job, and have done. But there's far better options out there when you can solve a problem with any language.

>>53797827
You might be happy to know that there's support for type annotations in Python 3.5 out of the box now, and IDEs / Editors will easily be able to infer types and to type-checking using that, before running the code. So at least some part of your worries might be alleviated.

Depends on what language you want to learn

>>53798406
Its not that hard, actually I'm not a researcher, just amateur that doesn't afraid of reading papers. Searching parameters of neural network by GA is 5 lines of pseudocode.
Didn't you thought that you could use all your dozens of cores to rapidly evolve & test solutions to your problem? Our computers are universal search machines, and yet we use them for stupid shit.
We could literally evolve (at least some form of) AIs in our machines.
>>53798544
Oh, I considered something like this. Basically creating random Python bytecode instructions at runtime and evaluating the resulting function result with some kind of fitness function. But I am almost positive overfitting would be a problem in all scenarios.
I guess I dont know enough about how all the caveats and how to avoid them.
>>53798456
Just pick a language a learn the basics. Basics are iteration, datatypes, variables, arrays, functions, operators, conditional statements, input/output, recursion. Then move on to object-oriented programming. If you have built this foundation there's no stopping you.
>>53798533
What is a fairly basic one?
I have a C tutorial program that has to iterate through the below arrays and output the product of finite values in the array:
double x2[] = { NAN, +INFINITY, -INFINITY };
call_function( "No finite values", x2, 3 );
double x3[] = { 1, 2, 3, 4, 5, 6, 7 };
call_function( "Several finite values", x3, 7 );
double x4[] = { 2, M_PI, NAN, 3, INFINITY, 4 };
call_function( "A mix of finite values and infinities", x4, 6 );
My issue is in the function that does the calculating, I have initializeddouble currentProd = 0;as a counter. C doesn't allow a sort of completely empty initialization (makes it a value of what ever is currently in that mem loc, so for most purposes it's really bad).
So I want to iterate through and have the first finite number assigned to currentProd, then on the next loop multiply currentProd by i (what ever the current is). I want to do it without nesting another if or else to check if currentProd is still 0. Or is that the best way? Clearly I am shit at C.
>>53798518
the directions talk about the producer/consumer threads in the singular

nm think i figured it out. i'm going to just have a global count variable, set it to the right value in main and then use it as the producer's while loop limit.
>>53798622

>Oh, I considered something like this. Basically creating random Python bytecode instructions at runtime and evaluating the resulting function result with some kind of fitness function. But I am almost positive overfitting would be a problem in all scenarios.
That could work but
1) Not all sequences of bytecodes are legal
2) Python is 100 times slower than C.
I went another route: just implement a simple forward only RNN and search for weights with GA. It worked, but perhaps due to quirky environment and fitness function the robot sometimes stalled (the task was to avoid blobs). With LSTM that could work better.
I'm planning to do it again, now I'd try some simple bytecode of my own. Or a threaded code. The only things that matter are:
1) There should be some sequence of code that produces the solution
2) It is desirable that said sequence would be short and there were multiple variants of it in solution space.

>>53798632
What are some good books on it? And what do you mean by messing around with the web?
>>53798600
so explain this in detail
you get a command line argument detailing how many times your producer runs and the consumer needs to consume basically after each time producer is called?
if that is true then just use a while loop calling producer first and then consumer.
unless there's some other shit I am missing.

Oh it's like it's 60s all over again

>>53798572
Assign currentProd to 1 instead of 0
>>53798657
True, but since most of the existing client-side code on websites is Javascript it's useful to learn and be able to read.
>>53798685
Writing scripts for simple things like removing elements you dislike and stuff, sky's the limit. I don't know of any good books, it's pretty easy to find web resource sthough.
>>53798572
Just make currentProd = array[0], and start your for loop with index 1 ie:double currentProd = array[0];
for (int i = 1; i < size; +++i)
{
/* your code here */
}

C#, Python, C when it is needed. You have no clue about programming, you only challenge others with buzzwords you got from /g/ and half-truths you collected during your wasted lifetime spent on this board. Go away, be sad and pathetic somewhere else.

if (isnormal(arr[i]))
prod *= arr[i];
printf("%f\n", prod);
}

idk, if a learning algorithm that after training on gigabyte of data eats your pixel array, char array with question about your pixels and computes a plausible answer in natural language is not AI than I don't know what is AI (this prof guy knows better desu https://www.youtube.com/watch?v=F2bQ5TSB-cE ).

as I said, throwing around nonsensical bullshit and empty challenges. You must feel at least a little bit introspective right now -- there's always the chance to change it.
Just go actually learn something useful instead of pandering C++ and being forever stuck on the 4th chapter of the book you bought that's much too big for you, love.

That won't work if the first element is NAN or +/- INFINITY.

Here's what Rob Pike says re: algorigms and data stuckers:The following data structures are a complete list for almost all practical programs:
array
linked list
hash table
binary tree

I shouldn't solve problems in a brute-force manner, I should make more stable fitness function and better controller instead.

Yeah, both stacks and queues are usually just abstractions of the listed data structures.

It's natural in the same way Microsoft Word's UI speaks to you in natural language. Image recognition, even when using neural networks, has no understanding of underlying concepts, only string tags associated with data sets.
I bet you think chat bots like Tay can hold an opinion too.

Define "understanding". My definition: understanding means computing compact (in inf. theoretical sense) representation of data suitable for further computation.
This neural network falls under my definition, it computes abstract representation of a scene and uses it to answer a question about a scene in natural language. It generalizes to images and questions it has never been trained on.
Of course humans probably have a more versatile and compact representation of the same scene when they see it, so they understand the scene better. But this understanding is still understanding.

Stacks are just vectors or lists with a restricted set of operations.
Vectors are just arrays that can resize. Alternatively, arrays are just vectors that can't resize. Take your pick, really.
>>53798943
Compilers and interpreters aren't practical programs? Programs that process speech aren't practical? To be honest, I think ASTs may see just as much use as BSTs... at least in a lot of my use cases.
in C++ if i have a method definitionvoid addAttraction(const Body &other, double &xForce, double &yForce);is it possible to pass it some element of a double array instead? e.g. if i was to call it like thism_objects.at(i)->addAttraction(*m_objects.at(j), totalForceArray[i][0], totalForceArray[i][1]);
>>53798937
I make real world pay and I basically only ever use arrays, lists, and trees, the occasional hash table. That list is pretty accurate imo.
>>53799006
>Compilers and interpreters aren't practical programs?
He says 'almost all' because how frequently are you going to be writing a compiler or interpreter?
>>53799006
>Vectors are just arrays that can resize
What? A vector is an element which has size and direction, or maybe the special case of a matrix that has only 1 dimension.
>>53798418
hooray for someone actually giving the right answer.

>Stardew Valley was created entirely by American indie game designer Eric Barone, under the alias of ConcernedApe.[4][5] In 2011, Barone had graduated from the University of Washington Tacoma with a computer science degree, but had not been able to get a job in the industry, instead working as an usher at the Paramount Theatre in Seattle.[6][7] Looking to improve his computer skills for better job prospects, he came to the idea of crafting a game which would also pull in his artistic side.[6] Stardew Valley originally began as a modern fan-made alternative to the Harvest Moon series, as he felt that "the series had gotten progressively worse after Harvest Moon: Back to Nature".[8] Unable to find a satisfactory replacement, Barone began to create a game similar to the series, stating that his intent was "to address the problems I had with Harvest Moon" and that "no title in the series ever brought it all together in a perfect way".[4]
