I'm working on a stylometry program desu.

I realised that a supervised learning algorithm using user provided labels (user names) is retarded, so I'm grueling through the math to get an unsupervised learning algorithm working.

Just coded a naive Llyod's algorithm, about to turn it into a smart one using the triangle inequality.

All trends seem to be moving into deep learning and stuff like that but I'm not smart enough for that and I don't know enough math

I started with webdev, then moved to Java (did a MOOC), then to C#, now I made a game in C# /Unity

So I know OOP fundamentals and decent amount of Java and C#

but nobody's gonna hire me if I only show a game in my github

Any advice what's a good way to get a job in any related field, what should I focus on? I'm in Europe

where are the job trends going?

>>57898188
Machine* learning

And home automation.

Video gaming is dead. Ed tech will die. Mobile is dying. AI is the only thing left.

>>57898188
Don't bother following the "job trends" or you'll always be way behind the people who always specialized in that thing which happens to be trendy now.

Pick your poison and as long as it's not terribly outdated, stick to it.

I know webdevs are naturally attracted to the shiny things of the month, but that's not what most serious employers want.

>>57898188
>deep learning
Well as far as job opportunities go its always gonna be a small field. Maybe you utilise it more in normal software.
And really when you do most programmers will just connect to the api and be done with it.

It's fun though.
>where are the job trends going?
As always performance programming is the one thing that stands securely. It won't ever go away. Learn that unless you're aiming/you're in a field that doesn't really care most of the time.

Find something you're passionate about though. I'm certain that in a job interview a person that's able to passionately describe their project will go way beyond a person which just follows the current fads.

I'm trying to write a small javascript guide for a friend of mine and holy shit I never realized how shit Javascript was before ES6. I can't believe I got used to a language where insane shit like

console.log(a) // undefined
console.log(b) // undefined
console.log(c) // ReferenceError: can't access lexical declaration e before initalization
console.log(d) // ReferenceError: d is not defined
a = 10;
var b = 20;
let c = 30;
console.log(a, b, c) // 10, 20, 30

can happen.

I don't have a CS degree. That sounds like something that requires a lot of knowledge about hardware.

>>57899169
All his inane pointless rules.

Never uses traditional for loops, always uses forEach instead. Never uses the 'this' or the 'new' keywords, always uses factory functions instead. You must put a space in between "function" and "()" for some reason.

template<typename T>
T average(T a,T b)
{
    return a/2 + b/2 + (a%2 & b%2);
}

Prove this wrong. I dare you

>>57899240
Prove that is right, first . I dare you

>>57899240
(a + b + 1) / 2 works just as well, though you may encounter overflow

BTW, replace x % 2 with x & 1

>>57899129
Yeah you're right. The problem was the test IP addr in the tutorial must be outdated. I replaced it with one from Google and now I get the results I expect.

>>57899233
why use for when you can use foreach?

>Never uses the 'this' or the 'new' keywords, always uses factory functions instead
They have the potential to be dangerous.

>You must put a space in between "function" and "()" for some reason.
never heard that one.

These are all guide lines. if you don't like em, don't use them. But if you do you them, your code will be safer and less prone to brain melting js-ism bugs.

>>57899268
>(a + b + 1) / 2 works just as well, though you may encounter overflow
That's the point. average of INT_MAX-1 and 10 is going to give wrong output.

>BTW, replace x % 2 with x & 1
Doesn't work with signed. Try -3 and 3

>>57899308
i was just trying to show a simplification :<(
why are you using signed ints baka

>>57899308
>Doesn't work with signed. Try -3 and 3
What?

3 is ..0011
-3 is ..1101

Works fine.

>>57899346
C and C++ doesn't standardize how signed integers work. Signed integers are compiler specific. They have a choice of one of three types of signed

On my machine, average(-3,3) becomes 1.

>>57899479
Oh, you're right. I hate how underspecified C is.

>>57899295
>why use for when you can use foreach?

Using forEach needs a new function, so if you're already inside a function and you want to return a value, it can get autistic and mess up.

For example:

function contains(array, word) {
    array.forEach((x) => {
        if(x === word) {
            return true; 
        }
    })

    return false; 
}

A non-autist way to do it would be:

function contains(array, word) {
    for(var i = 0; i < array.length; i++) {
        if(array[i] === word) {
            return true; 
        }
    }

    return false; 
}

>>57899507
well you wouldn't use a foreach in that situation anyways for the exact reason you gave.

>>57899536
I'm not completely against forEach, my point is Douglas is against traditional for loops entirely even when sometimes they are more appropriate than forEach.

>>57899507
Not being able to deal with nested functions is not a good reason to not do something.

>>57899561
which one is faster?

that's what matters

>>57899507
Why would you use

foreach

to test for a condition?

Doesn't Javascript have an equivalent to something like:

if (myList.Any(x => x === "ass")) return true;

That's not a case against foreach at all; it's just using it wrong, and a for loop is not the solution here.

>>57899507
In Python that's just:

contains = lambda arr, word: word in arr

Hey guys, new to programming, should i start by learning java? If not, then is C++ a better choice? If neither, which language would be good to start with? Thanks in advance!

>>57899561
I haven't used a traditional for loop in the entirety of 2016.

Why use for loops when you can use set comprehension?

I can't think of a situation where they would be more appropriate unless you're working with a case that you need to ultra-optimize (which are very very rare).

>>57899561
>Douglas is against traditional for loops entirely
really? Kinda doubt that. there's scenarios where you absolutely need a for/while loop.

>>57899593
what's your current occupation, and why are you interested in programming?

>>57899573
>that's what matters
only to bad programmers

>>57899593
C++ is a fine choice, but I think that C# is the best first language between C#, C++, and Java.

Avoid Python as your first language, but it's not a bad language to know.

If you want to get into low-level stuff (unlikely), then start with C.

>>57899614
>Avoid Python as your first language

>>57899614
>If you want to get into low-level stuff (unlikely)
Stop projecting. Not everyone is a code monkey.

>>57899630
Python is extremely different from C, C++, Java, and C#, which are the other huge languages from a pure job-count perspective.

It would behoove anyone to know one of the former 4 languages, rather than the latter.

>>57899599
Of course you haven't, JavaScript programmers have been memed by Douglas Crockford into not using traditional for loops any more.

His only complaint? He doesn't like seeing three statements on one line. That's his only problem with traditional for loops.

>>57899603
Nah, it's true, in one of his presentations he says he only uses forEach. He used to use "while" loops, but he's dropped those in favour of recursive functions.

I'll see if I can find it for you.

Are all servers daemons?

>>57899660
I'm not a Javascript programmer.

Though I have no idea who this person is, I agree with him I guess; it's easier to read set comprehension than index-based iteration.

I'd like to see how my normal approach differs.

>>57899706
how deep are you willing to go?

Is there any literature that actually confirms that programs written using static typing actually result in fewer bugs?

>>57899660
well, i guess you can use recursive functions in most cases instead of while. And there's advantages to doing that too. Less mutation namely.

>>57899706
Sounds like you'd be right at home in C or C++ then, ignore my previous recommendations of C#, and I don't think Python or Java is up your alley either.

I'm assuming you'd like to potentially do programming as an occupation. There are other languages that let you manage memory and get "closer to the metal", but C and C++ have a massive amount of jobs.

sort of. But it's a very difficult thing to prove empirically.

I'm sending strings back and forth between a Python program and a C program via a TCP socket and using the struct module.

>>57900117
I think it's better to strip null terminators in Python.
If server crashes, finding NUL-less strings will cost more time, than NUL-ful strings in Python.

>>57900117
Just prefix the message with the length, strip them on the client side, add null terminators on the server side.

>>57900188
That's what I'm currently doing, but I was mostly wondering if it would make sense to have both the adding/stripping on one side rather than stripping on the client side and adding on the server side.

0 denotes the first element, 1 the second, 2 the third.

If you write [0:2], you want the elements at positions 0, 1, and 2.

Hi there,

I've got a problem here and would like to borrow a programmer's brain for a minute. I have data in the form of (provided below) and want to know what is needed i.e tuples, dicts, lists, arrays etc.

FRUIT A
----------- African Banana

---------------------------------- Green
FRUIT B
----------- South American Apple
---------------------------------- Yellow

I'm think that each needs to be a list, but I am unsure if that would work with this pseudocode

for FRUIT in FRUITS:
    for Regional Fruit in Regional Fruits:
        ... I don't know what happens hear, but I want it to be like this:
Regional Fruit (African Banana) 
do command for red | grep African Banana
do command for blue | grep African Banana
do command for yellow | grep African Banana
Regional Fruit (Asian Banana)
do command for red | grep Asian Banana
do command for blue | grep Asian Banana
do command for yellow | grep Asian Banana

function generate(lines, complexity, counter){
    counter++;
    if(counter == complexity){
        return lines;
    }else{
    var initlength = lines.length;
    var linescopy = lines; 
    lines = [];
    for(var i = 0; i <= initlength-1; i++){
        var newlines = splitLine(linescopy[i]);
        lines.push(newlines[0]);
        lines.push(newlines[1]);
    }
    generate(lines, complexity, counter); 
    }
}

I'm trying to do the midpoint displacement algorithm for 2d simple terrain generation in javascript/html5 canvas and I wanted to make it recursive.

splitLine()

takes something of the form [x1,y1,x2,y2] and returns something of the form [[x1,y1,midx,midy],[midx,midy,x2,y2]], which is why the master lines array is emptied each time.

Anyway I'll worry about something to get it drawn later I just want to have things in an array first. For now I'm using nodejs.

On paper I've very verbosely gone through what

generate([[0,65,500,179]],2,0)

would look like, just some sample slanting line to be defined as the initial one, that the terrain will fractal off of. And I can't see an issue, because when generate calls generate in itself the first time, that counter is then = 2, which should just return lines immediately, which should be something of the form [[0,65,250,y],[250,y,500,179]].
But it isn't, lines is just undefined.

When I remove the recursion and just do one go, setting counter to one less than complexity in the function call, it works correctly.

So I, uh, built an Election Forecaster.
It's kinda like Nate Silver/538 and Sam Wang/Princeton Election Consortium and their forecast models.
At least, a lot of the groundwork, theory, and math is built up on their work, or at least what I could cobble together from what they were willing to divulge publicly.

I'm surprised with myself really. It managed to predict 48/51 states right, missing only PA, MI, and WI.
It managed to completely out do NYT, HuffPo, and PEC as well and it got the popular vote down almost perfect. The model predicted Clinton winning the popular vote by 2.4% and the final result is her winning the popular vote by exactly 2%, predicting a far tighter race than other forecasters.

I honestly thought it would just implode and be horribly wrong on all counts.

>>57903113
>When I remove the recursion and just do one go, setting counter to one less than complexity in the function call, it works correctly.

I should add, this kind of goes without saying, it just returns whatever you inpuitted for lines immediately.

What I meant to say is that when I change the function to look like

function generate(lines, complexity, counter){
    //counter++;
    //if(counter == complexity){
    //    return lines;
    //}else{
    var initlength = lines.length;
    var linescopy = lines; 
    lines = [];
    for(var i = 0; i <= initlength-1; i++){
        var newlines = splitLine(linescopy[i]);
        lines.push(newlines[0]);
        lines.push(newlines[1]);
    }
    //generate(lines, complexity, counter); 
    //}
    return lines;
}

It works correctly, returning [ [ 0, 21, 250, 93 ], [ 250, 93, 500, 92 ] ] when I ran it just now. So the meat of the function works, so I don't know why, in the example >>57903113 with complexity 2 and counter 0, it doesn't work, even though it's doing the same thing as this.

Based on polls, yes.
Gather polls per state & DC
Predict the probability of winning each state (the difference in the polls between you and the opponent is greater than 0)
Use that to predict the probability of winning the electoral college.
There's a panel on the page explaining the methodology.
Sam Wang/PEC do a far better job explaining this kind of thing than I do.

>>57903463

Thanks anon.

I see a lot of people using these terms interchangeably

>>57903407
Scripting is writing scripts. Generally short, tool/utility/onetime use files written in a high level language and interpreted on the spot. Generally no thinking other than basic sequential order of execution and functionality is needed. Programming is writing programs, usually compiled but not always, using techniques related to computer science (abatraction, object or inheritence model, efficiency, time/size complexity, etc)

>complaining about JS floats when his language doesn't even have rational literals

>>57903506
Please include the complete list of polls you excluded, and the reasoning for each.

This would be more impressive had you done this before the results; after the fact, you could have biases towards which polls to include, and especially in your weighting.

Rust or C++14?

>>57903565
Rust if you want to keep your sanity but C++ if you want to be relevant in current year

>>57903507
there's also this meaning of scripting: >>57903513

i was more thinking of the type of scripting such as for autohotkey, you tell autohotkey what to do, or you script some events in a video game, you don't modify the core aspects of the game you just use some pre-programmed functionality

>>57904168

function splitLine(line) { //line is array of the form [x1,y1,x2,y2]
    var midx = (line[2]-line[0])/2; //split at midpoint 
    var midy = randIntInterval(0,200); //change 200
    return [[line[0],line[1],midx,midy],[midx,midy,line[2],line[3]]]; //return two new lines in form of array of lines
}

200 comes from the height of the canvas, but I need to change it so that it's something less every time, because I'm doing http://www.gameprogrammer.com/fractal.html#midpoint

I just want to have a bunch of lines properly in an array, and I want to make the generate function recursive. It works exactly like I want it to unless I make it recursive or try calling it on itself.

anyway yeah generate() just takes that and splits it up, then puts it into the lines array.

oh, well shit. what's it do then?

>>57904250
It just means you now have two references to the same array.

In the case when you take the result and pass it in again as a literal, you are essentially doing the copy that is omitted when you do it programmatically. The same thing will happen if you do:

result = generate(...);
generate(result);

>>57904235
>[x1,y1,x2,y2]
Why are you writing code like that anyways? Why not use objects? like:

function splitLine(point1, point2) { //{x: 1.0, y: 1.0}, {x: 1.0, y: 1.0}

>>57904279
well I've changed it to var linescopy = lines.slice(); and still no luck

>>57898474
>That sounds like something that requires a lot of knowledge about hardware.
Well arguably yes. And hardware changes.
But there's current truths about performance programming like how memory access is expensive. That could potentially change. But every single one of those changes happen individually so most of what you've learned remains true.
I don't think it actually requires that much hardware knowledge. You just need to know the interface of the device you're dealing with. The CPU instruction set and it's throughput/latency. How fast memory is and what a cacheline is. How to profile code and what you can do to improve the performance.

Standards are fairly low right now. Most programmers are entirely in the "big-o is all the optimization i need" headspace and it's not really true unless your standards are very low.

So it's worth looking into. I'm not sure how much it fits your idea of fun though. Most who do optimization work as their passion get a kick out of making things go fast and like detail work.

>The most fun I have when I program is when I am dealing with purely abstract, logical problems, no mathematical but algorithmic.
>logical problems
>not mathematical
Not sure what you mean exactly. Every logical problem is mathematical. What I think you might mean is that the constraints you have in mathematics aren't applied and you're dealing with the real world. If you have a math problem you can't usually just add another piece of information to the problem to help you solve it. That's usually what you can do in programming.
I can't tell you what suits this description though.

Dumbass

My program crashes when it reaches this line
parseDate(argv[1],&(newItem.due));
But when I use a different argument it works.
Here's the function

char *parseDate( char *s, Date *d )
{
    parseInt(s, &d->year);
    s++;
    parseInt(s, &d->month);
    s++;
    parseInt(s, &d->day);
    
    return s;
}
When I call the function parseDate using a different argument like a string it works. 
char string[100];
parseDate(string,&(newItem.due));
The second paramter works and the function itself works too it's just the first parameter that's faulty.
The problem is that I can't change it because it's an assignment and I have to use argv[1] as parameter.

>>57904644
seems like it's returning a new array, but also editing the array you passed to generate(). Not sure why though, I can't see where that's happening in your code. Are you 100% certain it's running the code you just posted?

Exactly.

>>57904850
Posting before the bump limit

Scripts have a single input usually defined in the body of the script. Programs are written to deal with undefined input to be supplied at some later point.

Example:
Your professor wants you to compute whether a certain 16-digit number is a valid credit card number.
>script
You write a file where one of the first lines is the 16-digit number and the rest of the file computes whether it's valid.
>program
You write a file that accepts a number as input from the command line and computes whether it's valid.

>>57904024
okay I have absolutely no idea why but getting rid of initlength and just using linescopy.length in the for loop makes it work now (and changing the definition of linescopy to be lines.slice()).

the issue now is making it recursive

>>57904932
But I write Python *scripts* that take input from sys.stdin, what now?

>>57905042
Then you've written a program.

>>57904932
No I find wikipedia to be quite accurate:
>A scripting or script language is a programming language that supports scripts, programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator.
Basically if your language has an interactive interface it's probably a language that supports scripting. (Bash, Batch, Python etc)
If it doesn't (C,C++,asm) it's not a scripting language.

Getting anal about definitions is stupid though. It's just a term people use to distinguish two sets of usage cases.

>>57905119
Supporting a script does not mean that everything written in that language is necessarily a script.

>>57905119
> programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator.

Except that applies to every interpreted language.

>>57905149
I think the idea of a "scripting language" is a useless description anyway. Saying something is a scripting language sounds like it's describing an inherent feature of the language, when really all wikipedia's definition is saying is that a REPL exists.

I think that if the distinction is to be of any use at all it needs to describe the products created with the language, not the language itself.

>>57905149
It actually applied to every langugae. Some langugaes just support scripting better than others.

>>57905247
Then again, we're stuck with the abscence of definition what scripting language is.

>>57905149
>one by one by a human operator.
If you don't have an interactive mode where you can do
>c=a+a
for instance and have that effect persist enough for a human operator to use it.
An interpreted language just means that there's a text processor that executes code based on the text.
it doesn't specify that a human can manually interact with the process.
Ignoring the interactive mode for python you can't really have a manually human operated process unless that's part of your implementation (you for instance write a python interpreter or have the python interpreting functionality in the language read from stdin).

So it's the existence of a (standard) interactive mode that makes it a scripting language according to this definition.

>>57905294
that anon above just said it:
>>57905119

A scripting language a langugaes that supports scripting. A script file is a programming langugae file that can be executed directly without having to be manually compiled to a separate binary first.

>>57905303
And that's stupid. That would imply there was one specific day when Python went from being not a scripting language to being one, and that day was the release of the first REPL.

That's just silly.


>>57905333
scripting =/= interpreting

>>57905360

I didn't say anything about intreprettying

>>57905303
>So it's the existence of a (standard) interactive mode that makes it a scripting language according to this definition.
Basic, Erlang and Prolog are scripting languages then?

>>57905333
>A script file is a programming langugae file that can be executed directly without having to be manually compiled to a separate binary first.
That's what called interpreted language.

>>57905360
>that's silly
How so? Seems like a fairly arbitrary way of dismissing this. You'd prefer it not to be the case.

>>57905410
You said
>can be executed directly without having to be manually compiled to a separate binary first
which is the definition of an interpreted language.

>>57905416
>>57905434
>That's what called interpreted language.
that's not at all what an interpreted language is. The code file is still compiled, just not manually.
