>In 2001, Vilayanur S. Ramachandran and Edward Hubbard repeated Köhler's experiment using the words "kiki" and "bouba" and asked American college undergraduates and Tamil speakers in India "Which of these shapes is bouba and which is kiki?" In both groups, 95% to 98% selected the curvy shape as "bouba" and the jagged one as "kiki", suggesting that the human brain somehow attaches abstract meanings to the shapes and sounds in a consistent way.

>Ramachandran and Hubbard suggest that the kiki/bouba effect has implications for the evolution of language, because it suggests that the naming of objects is not completely arbitrary.

>>56878724
probably statements that are only true if you're a mentally deficient script kiddie.

>>56878776
Not programming related, but I did related the curvy figure to "bouba".

I have co-op job offers from two different companies. One is a 6 person team with small dingy office and the other is a 30 person team with a nice office. Both are mobile development jobs. Which one should I pick if I want to learn the most?

How do I estimate the upper bound for how much I can compress some arbitrary data before it has all of the repetitiveness squeezed out of it?

>>56878587
I think I'll do that too.

>>56878856
You will work with all 6 in the small job, work with maybe 1 or 2 in the big 30 job. You will not learn from the others in the 30 job, you will be doing nothing but learning in the 6 job.

anyone else program(ming) in Fortran95?
Im designing a program that works with Pythagorean triples and force vectors

>>56878577
My first language I learned in school was VisualBasic, then I learned Java, then at the beginning of last month I started teaching myself Fortran95.
Really one thing I like about programming is if you have good logic skills and can understand the basics of syntax learning a new language is easy
.>>56878638
if you think you only need Java then you should work for Notch designing only Minecraft mods, C/C++ is useful for many a programming task, Python is good ive heard, F95 can be used around the industry
>>56878865
very carefully :^)
desu I dont really know. what kind of arbitrary data are you working with?

>>56878776
sounds have different textures. so much of science is stating the obvious

>>56878577
C

>>56878939
It's still interesting to note that language-concept mappings aren't entirely arbitrary.

>>56878776
Sounds neato but there are some problems.

This is just one example of two highly different letters (in sound and picture, K and B are as "opposite" as letters can be) with two pictures which happen to reflect their phonological and pictoral representations (B: "Bulbous", pronounced with soft air through the lips, rounded letter; K: Jagged picture, harsh tight sound pronounced with roof of mouth and tongue, brings to mind Crackle, Kick, Karate, etc.).


If I give you these symbols:

| | AND |o

and ask you to assign then either "Herbert" or "Patricia", I shouldn't be surprised if you pick "| |" for Herbert and "|o" for Patricia, when there are obvious symbolic similarities between those two letters and the symbols provided, especially when the two are contrasted with one another.

However "|o" would not necessarily bring Patricia or even "P" to mind if you just laid out the symbol itself. It is only in the context of providing the words Patricia and Herbert that you assign them to two things. For there to be a real consistent relationship, you'd have to show images and ask people to relate them to words, which is so variable that there is actually a word for this sort of thing in psychology: a Rorshach test.

There is no reason to suspect some non-learned internal mechanisms which assign pictures to sounds. Differences in characters of different alphabets should be all the proof you need.

>>56878577
Haskell

>>56878776
Kiki is a harsh sound. It uses jaggy letters the the Ki sound is short and hard. Bouba is far less so. Seems obvious to me

178KB, 700x1050px

>>56878511
Why is this?

>>56879173
That addresses letter -> picture mapping but not sound -> object mapping. Bouba makes a "round" noise, while Kiki is very "sharp". Bouba sounds stretched out and fluid, while kiki sounds short and rigid. Much like their associated shapes in that picture. It would be fun to see the experiment replicated on people with different native languages / people who can't speak English.

>>56879173
>>56879207

Also, the original experiment was performed on Spanish speakers, although with the words baluba and takete.

Still a pretty limited group of people. Chinese/Japanese/Korean respondents would be fun to see.

>>56879279
I can read that you both seem to focusing on the visual shapes of the symbols B and K.

>>56879337
I was literally talking about the harshness of the sound of K. Why are you talking about languages when you can't pickup on reading comprehension? K is a jagged sound, when with an I it produces a short, harsh sound that requires you to push a lot of air out. B does not, it's phonetically opposite in that little air comes out and it's easy to say. When coupled with the aou sound, it's long, and requires a relaxed mouth. Of course people associate those sounds with harsh/soft images respectively.

키키 바어버

Compile-time data structures when?

>>56879374
What do you even mean?

>>56879361
Now you're just saying "K is associated with jagged, therefore K is associated with jagged".

The fact that most people think that [kay] is a jagged sound is just what the experiment demonstrates.

>>56879419
>The fact that most people think that [kay] is a jagged sound is just what the experiment demonstrates.
That's not subjective. It's a harsh sound because it's short and loud. There's no way around that, what's your argument here, other than pretending you don't know what the words "harsh" and "soft" mean?

>>56879374
Do you mean static types? Because we have those in every non-pajeet language.

>>56879374
just write all your programs exclusively with template meta-programming in c++ header files

>>56879430
I don't have an argument. I was trying to understand what your argument was.

I still think it's interesting that one associates both an audio element and a visual element to the same concepts "harsh/jagged", even to the point where you think it's idiotic to question it.

>>56879391
Generation of data structures at compile time. Let's say you are making a compiler and you are generating a state matrix. The language is known at compile time and no cycles what-so-ever should be spent at runtime generating those structures. The structure should be created and stored in the executable. Most languages don't support that.

>>56879498
It's simple, it really is my dude

Ich habe drei Katze
That is a harsh sounding sentence, because the "ich" and the "Kat" require you to move your mouth into a somewhat uncomfortable position and they produce a lot of air. More air means more sound, more sound means loud, loud means harsh.

Run your nails down a chalkboard. It makes an "EEEEE" sound. It's unnerving, or "harsh". Now imagine running your nails down it again, this time it makes a "bououuuuuuuuuuuu" sound. It's not annoying now is it?

>>56879519
D can do that with inline variables
with some doing GHC/Haskell can do that, but you need a way to forcibly tell the compiler to (e.g. INLINE pragma or template haskell quote)

>>56879519
constexpr?

>>56879229
We live in a consumer society that worships bullshit material objects. A much larger percentage of the population knows what an ipod and ipad are than who know that c and unix are.

>>56879527
>loud means harsh
no it doesn't. not necessarily
the fact that you think it does is what's interesting about this experiment

And your other argument seems to now suggest that viewing the kiki shape is unnerving and annoying.

>>56879552
It's a start, but how about compile time support of the entire language?

>>56879535
>inline variables
I'll look into it.

You can't allocate dynamic memory compile time, no. This bothers you, somehow?

>>56879588
What?

>>56879608
I think they're working towards making constexpr work on everything that's constexprable.
Although, maybe not. That might potentially lead to huge executables. Were talking about unrolling our entire codebase here.

>>56879608
>compile time support of the entire language

why would this be necessary

is this what wdg is all about

>>56879679
Well it's something the programmer should have easy control over. If they can afford huge executables let them. But in certain cases like compilers where each use must be serially as fast as possible large embedding certain core data structures enable decreased execution at slightly larger executable size is a good trade off.

kalman fuck you

>>56879769
I can't even listen to that voice for long enough to find out what that has to do with wdg

>>56879737
I should mention it's for work. I feel like "user inputted" variables wouldn't be too professional.

>>56879758

What's the fastest way for me to code smartphone apps? I have a couple of simple ideas and it feels like a decent way to break into programming. I don't have a lot of experience actually writing software, but I can into terminals and write scripts.

I've learned the ascii codes for some of the non-english characters i use often and tap them out on the keypad. It's really annoying when i use linux though. Linux won't let me do that, and there doesn't seem to be way to configure Linux to let me do that.

>>56880120

I don't remember exactly, DESU.

What I do recall is this: there were shortcuts available for common Euro-language stuff (tilde, accent, umlaut, etc.) and switching between English and Japanese was easy, just Command+Space.

Windows now has Win+Space to rapidly switch languages, but before you always had to assign some hotkey like Ctrl+Alt, which was comparatively clumsy.

From memory, I want to say that Option+N would make an "ene".

>>56880244
>DESU.

Any other frameworks that could help build a game engine? Maybe one with a lot of stuff for animations and collisions. Box2D?

I'm working on a project for class where I'm learning how to encrypt messages sent over a network between a client and a server. It's my first time using C++, but the syntax is just so strange.

>>56880561
I unfortunately don't know much about game frameworks, honestly. Generally, the more stuff your framework includes out of the box, the less control you have over those systems. Animations wouldn't be too difficult to make yourself if you're using sprites. And if you are going for the retro style, collisions shouldn't be too difficult either because your sprites will be pretty blocky.

I really don't like weakly-typed dynamic languages, but fuck, python makes it SO EASY to create complex data structures.

tuples as return values, dictionaries (hashmaps) with crazy combinations of other structures as keys

I miss static typing, but compared to Java, creating data structures is so simple.

Is there any language with middle ground? Perhaps a statically-typed language that makes it really simple to make complex data structures?

As far as web crawlers I've used before, it's actually fantastic. It takes almost no time at all to check for duplicates because it uses a custom trie implementation and can filter for regular expressions (for instance, right now it's downloading every fullsize media file on the entirety of 4chan, ignoring thumbnails and repeats- so far it's got 2gb of unique content within ~12 minutes)

She basically told us to write down our order of preference between C, C++, Java, and Python, and she'd come back with the choice of language for all of the class' assignments.

In any case, I've used Java before, and I've used Python before, but given my choices, I'd rather C++ or just plain C.

Inter-process communication. Which is what you should be doing in Python and Ruby if you want to do anything in parallel, since neither is capable of concurrent native threading because of the GIL.

Currently I'm working on a dominoes AI, so far I just have the Tile, Player and gamestate classes set up and it'll follow along a game and tell what player potentially has what tile. Anyway I'm gonna try running a BFS which is probably gonna turn out awful due to the complexity inherent in non deterministic games then after that fails I'll try implementing some form of Monte Carlo tree search.
P.S. I'm hacking all of this together in Java.

Hello /dpt/ !

I require your help. I need to write a C# program that makes the user input his birthday date and then shows his age + 10.

This is my code so far:

using System;

namespace AgePlusTen
{
    class Program
    {
        static void Main()
        {
            Console.WriteLine("Please enter you birthday as MM.DD.YYYY :");
            DateTime BirthDay = DateTime.Parse(Console.ReadLine());
            int age = (int)((DateTime.Now - BirthDay).TotalDays / 365.242199);
            Console.WriteLine("You are " + age + " year(s) old.");
            int sum = (age + 10);
            Console.WriteLine("After 10 years you will be " + sum + " years old.");
        }
    }
}

How do I make it so it uses EU formatting and checking if the input is correct (otherwise it should ask the user for new input)

>>56883266

First things first: learn how functions work and don't write them inside of main. Don't do this:

int main()
{
    void foo()
    {
        /* stuff */
    }
    foo();
}

Instead, do this:

void foo()
{
    /* stuff */
}

int main()
{
    foo();
}

And pass your arguments via parameters, rather than making them global.

How much JAVA I should know before I can get an entry level JAVA job?

I'm a little older and started later, I want to change career because my previous job made me want to kill myself.

What's the best route for me?

I'm in the middle of a Finnish University JAVA programme that teaches the basics of Java OOP

After that, I'm thinking of a few months of making Java apps just to practice, semi - real projects

I thought of learning the Android ecosystem next... and make some Android apps

is this a good path?

is it better to go freelance since I have no CS degree and I'm a little old?

or is it better to look for an Android Java entry level dev position ?

Well for starters, it's not actually allowed in standard C. GNU C allows it as an extension, but it's not an extension any C programmer ever actually uses. It makes your code harder to read and maintain, and most importantly, those functions can't be called from other functions in your program that may, for example, be in different files altogether (and when you don't want those functions to be visible, the standard keyword to use is static).

Basically, just don't nest functions. Ever.

>>56878577
You shouldn't ask this here.
Personnally I'd go with C because it will teach you rigor. You will tear your hair at the beginning and you will use Stack Overflow a lot, but this is the way to enlightenment.
If you want to become a dirty ass programmer, learn Javascript first. It will teach you how to store -34.62 fishing rods in the cell with label "bear" in an array of desks. Then you will be too lazy to learn more rigorous syntaxes and you will never grow out of it.
PHP is pretty much the same, maybe a bit less dirty. But you have to learn HTML (and optionally CSS) first, which may be a good start because they're not actual programming languages.

If you decide to go with C and want to do advanced stuff, you might also want to have a Linux machine. Not saying that C on Windows is bad, it works well for most purposes, but holy shit the Windows Shell sucks.

If I write something like
char x=0;
x+=3;
there is no implicit type conversion going on, is there? i.e. this is not slower than if x was an int, right?

>>56883623
Oh I see thanks.

>>56883842
>this is not slower than if x was an int, right?
Why would it be?

>>56883842
char is just a smaller int (depends on the system inb4 autists)

>>56883842
x += 3

is the same as

x = x + 3

is the same as

x = (char)((int)x + (int)3)

>Kek
>GNU C > C
Laugh all you want, but there are cases where you can't use GNU C. In particular, you can't use it in the Intel C Compiler, which finds a number of uses on supercomputers.

>it's used in linux
It is not encouraged, and the style guide actually chooses its different brace style for functions on the fact that functions are "special" and cannot be nested in C. That said, I would expect that there will always be some code in the Linux kernel written by absolute retards.

Also, Linus says that if you need more than 3 levels of indentation, your code is screwed, and you should refactor it. Nesting functions brings in an additional unnecessary level of indentation, so fuck it, make it on its own.

>the global name space is not polluted
Make it static. Then, it's only visible within the file, and why would you ever write two functions with the same name within the same file?

>code locality is better
No it isn't.

>helps to avoid repetition of code
In no way does moving a function from file scope to nested avoid repetition of code. If anything, it may increase repetition if the same function is nested in more than one function.

>which is good.
No. You fail to grasp the purpose of a function. The point is to re-use code. If you do not wish to pollute the symbol table, you use the static keyword. Otherwise, you allow the function to be visible to other modules in your program so that it can be used as often as possible.

0 is not an identifier (i.e. a valid variable name).
Pick something else.

>>56883904

1. You don't.
2. "£" is a string, not a char.
3. £ is neither a string nor a char.
4. If £ could be fit as a char, it would be '£'. As UTF-8, however, it takes multiple bytes, and therefore cannot fit into a char.
5. 0 is not an identifier; it is a value. So as mentioned in 1, you fucking don't.

The function called at program startup is named main. The implementation declares no
prototype for this function. It shall be defined with a return type of int and with no
parameters:

    int main(void) { /* ... */ }

or with two parameters (referred to here as argc and argv, though any names may be
used, as they are local to the function in which they are declared):

    int main(int argc, char *argv[]) { /* ... */ }

The problem is that a very arrogant software engineer at work has basically taken control. She is charging full force on this big rewrite project and has convinced management to sign on. The problem is that the system is fundamentally broken. Basically, what we have is a sophisticated ETL program for managing insurance data. Currently, the system has the "transform" and "load" process being completely separate. There is very good reason for this. A LOT of additional steps can happen between the initial transformation and when it finally gets loaded. Additionally, the load process is non-trivial. It's actually more of a "merge and load". We have 100+ different transformers and the load process needs to merge them and perform cross validations before it puts it in the target database. So don't think of the load program as just a SQL insert. it's much more sophisticated than that. Somehow, this idea that the transform and load steps can be combined got spread and a rewrite project to do that commenced.

So now we have a situation where we have two very complicated programs being combined into a single monolith of even greater complexity. A lot of our other software that did those "additional steps" between the transformation and the merge/load process now have to be rewritten to accommodate that. So the rewrite of one project has basically been bloated into a rewrite of nearly our entire organizations software systems.

(continued in next post...)

continued from..
>>56885625

But it will be okay at the end, right? No. That's what I mean by fundamentally broken. A lot the things we NEED to do are now IMPOSSIBLE with this new design. It just won't work. It's now been four years, the scope creep on the project gets bigger and bigger and it's now reached a point where it's "too big to fail". Too much has been invested for the organization to back out now. Shit is going to hit the fan HARD.

The cause of all this is a single software engineer who managed to convince upper management that this was a great idea. Was anyone else consulted on this or asked for input? Nope. Literally EVERYTHING in a 500 person organization is changing because one individual is a bit of a control freak.

Already there is talk about her "transition". You might think that means she would be fired for gross incompetence, right? Nope. What I mean by transition isn't that she gets fired, but instead gets to move onto another project after this garbage goes to production. In other words, she gets to lead the charge, rule over everyone with an iron fist for 4+ years, then when the thing ultimately fails, she gets to divorce herself from any responsibility and say "not my problem anymore". That's fucking infuriating.

So she fucked up your software, but why do you want to leave? Is the work unbearably difficult or stressful now? If you are very familiar with the subject you could go work elsewhere in the field, tell them of your mistakes, and be that aggressive dick, but set things straight if they are out of line. If it ends up doing good you'll get a nice management job. Shit pays better even though managers usually do fuck all.

>>56885606

>a single software engineer who managed to convince upper management that this was a great idea.
But what made HER think it was a great idea?

>>56885640
Her gender isn't the issue. We have a lot of great female developers where I work. Also, there are plenty of men with the same kind of mindset. The worst situation was a couple years ago when some intern started committing code to a project I was in charge of. He was new, so I figured that maybe he got confused about what he was supposed to be doing and started working on the wrong project. I went and introduced myself, told him I was the project lead, and asked him about what he was really supposed to be working on since he wasn't on my team.

The intern looked at me with surprise and said, "But I thought Craig was in charge of this project?" I had no idea who the fuck Craig was. I had to talk to a lot of managers to figure out WTF was going on and why this unknown Craig person thought he was in charge of my project and why he was telling this intern to make changes.

Turns out he is such a control freak and wanted to impress this intern (how fucking pathetic can you get to want to impress an intern?), that he basically picked a random project to try to hijack and claim to be in charge of.

She doesn't think it's a good idea, just different. You've never heard this tactic before?

If it doesn't they get fired or leave and they do that shit to the next business they get hired at. It's a con, it's a self-important gambit, but it's common.

>>56885737
I've asked this many times. I think the project only exists to satisfy her ego and for her to have control over something. I got very hand-wavy, non-specific answers whenever I asked. The only real technical reason I heard was that in some specific error scenarios the data can get out of sync between a transformation and the load procedure. This requires starting the process over again with fresh data. It's really not a big issue at all. It doesn't happen often and is trivial to fix. Because the rewrite version of the project does the transform/load process together, there isn't an opportunity for an errant program to accidentally modify the data between those stages in an invalid way, thus it resolves that issue.

That's the closet thing I got to a real answer. It's a dumb answer though because we're basically trading one flaw that is easy to fix for an entire mess of technical debt and a billion other flaws. When I asked, "well then how do we do X, Y, and Z if the transformations and loading aren't separate?" and I never got an answer other than "I don't think that's an issue". It is an issue. It's a massive issue. It's just not an issue to her because she isn't involved in those projects that get fucked up by it.

Sure, but even still, how do you convince management it's a good idea?

>Let's combine two fundamentally different portions of our software solution into one mega-clusterfuck! Separation of concerns? pshaw.

devious? scale?
Some people will do anything to make more money. She was lucky really. If she came to me I'd tell her to fuck off, but that's because I know the business I'm in. Apparently, that business has middle managers who don't know anything about their industry and trust their knowledge (or fancy sycophancy) more than the judgement of their subordinates. Also if I was a low-level manager or project lead and I didn't agree I would've quit. No middle manager that listens to the snake oil salesman is worth working under.

She isn't my boss. In fact, my boss has been a total bro. I've told him how I think this project is going to be a massive failure and he's done what he can to make sure I don't have to be involved. He can only do so much though. When this shit gets turned on for real, it's going to affect nearly every project at our organization, so one day I am going to have to face the results. That's why I'm thinking of a new job.

in haskell this is just

load >>= transform

/!\ A L E R T /!\

Monads are the future.

Well management doesn't always know the business they are in well. Maybe it's just more pronounced in the software development industry. I hear all kinds of horror stories about incompetent management.

>she
and that project is going to be a waste of money and will never get done

monad transformer classes are pretty good

To add:
The middle manager probably also see the success of this change as a way to climb the ladder. He is in a comfy position where if it does work out he can claim the responsibility, and if it fails he can blame it on her. But that depends on how big the company is. You couldn't pull that off in a small company.

Jealousy for what? Because of your placebo? You are a living meme.
