FizzBuzz on C, C# and tried with Visual Basic, but the language is truly cancer.Sub Main()
Dim x = 0
For i = 1 To 100
x = x + 1
If x Mod 3 = 0 Then
Console.WriteLine("Fizz")
ElseIf x Mod 5 = 0
Console.WriteLine("Buzz")
ElseIf (x Mod 3 = 0) And (x Mod 5 = 0)
Console.WriteLine("FizzBuzz")
Else
Console.WriteLine(x)
End If
Next i
Console.ReadLine()
End Sub
End Module
Only the FizzBuzz part doesn't work.
I also triedElseIf (x Mod 3 = 0 & x Mod 5 = 0)
Who came up with the lie that you don't need math for programming?
Every non-trivial discipline of programming requires some form of math.
3D graphics is literally applied linear algebra.
>>53757701
Same here. With Javascript, whether I do modulo 15 or modulo 3 AND modulo 5, I never get "FizzBuzz" where 15 should be.
>>53757631
I haven't read them, but if he ever leaves neutrally elaborating and describing the facilities of early lisp, he will probably compare it to languages that were popular back in the Golden Era Of Artificial Intelligence, so you won't get up-to-date information anyway IMHO.

>>53757798
Yeah, C# and C just werk, maybe I just need better knowledge of VB, but I just learned it as a quick fun thing to do so I can't be bothered.int x = 0;
for (int i = 1; i <= 100; i++)
{
x++;
if (x % 3 == 0 && x % 5 == 0)
{ Console.WriteLine("FizzBuzz"); }
else if (x % 3 == 0)
{ Console.WriteLine("Fizz"); }
else if (x % 5 == 0)
{ Console.WriteLine("Buzz"); }
else
{ Console.WriteLine(x); }
}
Console.ReadLine();

>>53757939
Both of you have code that doesn't do what's intended: at 15, it prints Fizz and not Fizzbuzz, right? Ask yourselves WHY this concrete implementation, not the perfect abstract thing you had in mind, took that branch and produced that result.
Hint:If 1 == 1 {
println("indeed")
} else if 2 == 2 {
println("obviously")
}
What does this print and why?

Anyone here experienced with nodejs, socket.io, and spawning child processes in nodejs?
I've just started using require('child_process').fork to spawn new node processes, cause JavaScript's single threaded nature will mean my program will scale like shit otherwise. Problem is, I want to use socket.io inside these child processes. Should I pass the entire socket.io object to the child processes or what? I feel like I'm missing something obvious. I'm pretty new to nodejs.

Dunno what you're trying to say here - that child processed aren't needed to scale a web app? They really are for me especially as I want to run loads of instances of the same game code.

Much more than just 3D graphics. The real kicker is that you don't even really need to know much more than the basics. It can all be made pretty high-level and the machine is doing all of the work for you. You can get by on much less than what you'd learn in a college linear algebra course. It applies to enough that it does genuinely surprise me how many programmers don't seem to know the first thing about it. No matter what you do, it can't hurt to learn the basics in order to be better-equipped should it come up.

>Visual Basic anywhere
Trying to rip sprites from an old PC game. It's the weirdest thing. Every character has a charactername.out file which looks like this when you shrink the text down. My plan was to convert it all to pure ascii numbers and then find out which colour they correspond to. But then there's also what looks like interlacing going on.
Does anybody know anything about this?
Fuuck
So I have a derived class implementing pure virtual functions from a base class. I have another derived class, that uses the first derived class as a base class, but I want to implement the virtual functions from the basest class in the latest class. Shitty explaination to show what I'm talking about:
base class {
virtual fancyFunction() = 0
}
firstDerived Class : public base class {
virtual fancyFunction()
}
secondDerivedClass : public firstDerived class {
fancyFunction()
}
I thought doing this would be pretty easy; I just make the functions in the first derived class virtual, then reimplement these functions in the second derived class. However, Visual Studio won't let me to this. Anybody know why?

Learning through repition. The first few times you're exposed to a concept are the hardest; then as you are continuously reintroduced to it, more neural connections to it/about it are made, and the thought/concept becomes stronger. Then you learn related concepts, and the core concepts become even more memorable through association with the newer ones. As time progresses, the knowledge base grows, and problems become easier and easier to solve. Thoughts and ideas related to the topic become more complex, as the intricacy of internalized information becomes more and more detailed. You find yourself capable of doing more in less time, and can explain concepts or ask questions more descriptively and with better detail.
So yah, just keep at it.

Anyway, I don't know any universities that actually use visual-anything for CS courses. Shit, here they give first years a babbies intro to LaTeX in the first term's project week.
That said, if the databases and general "programming methodology" shit bores you, maybe consider CE or EE instead and head more into embedded development.
I'm finishing my EE this year, they don't teach programming very well but it's still much easier to pick it up when you have practical use cases rather than the non-stop theory train you get on a pure CS course.

For some reason the AS year is a lot easier than A2 for computing, but the coursework will bend you over and fuck you in the ass before you've noticed it's got a hard-on for you.
That said, there still isn't a lot of content to cover for the last exam so consider than an easy A*.
But it will help a lot for CS first year, you probably wont need to turn up to much at all, which sounds bad but first year doesn't count for shit so it's always easy anyway.
Soon as 2nd year rolls around you'll be back to the usual workload again though, and who knows, the content may even get interesting.

Anyone good with Node js and want to explain what's happening here?function incorrectCredentials(e, p) {
console.log('inside function');
requestS(url)
.post('/userLogin')
.send({email: e, password: p})
.end(function(err, res, body) {
console.log('end function');
var $ = cheerio.load(res.text);
var text = $('a[class=headerlogo]').text().trim();
text.should.equal('Incorrect credentials.');
res.status.should.equal(200);
});
}
When I run, it only prints 'inside',
why is it not going inside the end function?

You know that understanding a thing is a matter of memorizing the sub-things which constitute that greater thing, right?

Nah, my compilers professor made the mistake of categorizing them as interpreters. I pointed out that they interpret nothing and JIT the bytecode into native code at runtime. Although he did point out (correctly) that there are SOME implementations of the JVM that are interpreters of bytecode, and do not use JIT. Albeit, those are rather old.
>>53761672
They are though.
Java gets "compiled" into bytecode, which then gets interpreted by the virtual machine
>>53761772
>I pointed out that they interpret nothing and JIT the bytecode into native code at runtime.
I appreciate that you're paying attention in class, but don't be that guy.
>>53761751
You're initializing an array to null values. Generally you do not want global variables because you end up with issues like this. Make the array in the draw function to avoid the issue. What does your main look like?
>>53761827
Oh I understand now, thanks anon. I'm trying to figure this out as I go. I heard it's a good software to introduce myself to code so I'm using it for a couple art projects of mine and hopefully I'll find the boundaries of this and get excited to broaden into Java or whatever else fits my needs.
>>53761778
This might be true if we were talking about the JVM about 15-20 years ago.
Java bytecode isn't interpreted anymore though. It's compiled at runtime into native code. This is an important distinction, because with interpreting, you pay for the cost of parsing the meaning of the bytecode at every iteration. With JIT, once it's been compiled into native code, you're not touching the bytecode again until the process ends (or more bytecode is loaded and JIT'd).
>>53761820
Hey, it's important knowledge. I've met other people before who think Java is interpreted, and think that's the reason why it's slow. JIT is a one time cost. The JVM has other reasons why it's slow.
>>53761772

Sure, but the JVM is pretty god damned tasty as far as VMs go.
Really not all that bad performance wise.

if you bother reading some of the papers on why fast inverse square root works, you might be able to kinda generalize the method. maybe try reading http://h14s.p5r.org/2012/09/0x5f3759df.html or http://betterexplained.com/articles/understanding-quakes-fast-inverse-square-root/

have you ever heard of code golf?
Complete newbie here. I took a VB course and did okay but my heart wasn't in it at the time. I tried learning C++ awhile ago and played around in Code::Blocks IDE without a lot of success and sort of gave up again. I'm trying to pick it back up but before I do I wondered what you guys recommend for a good IDE to work C++ with.
>>53762124
Honestly, code::blocks is probably the best. Their site should have tutorials on how to navigate it and all that

That's cool, thanks. I'll keep with the code::blocks then.
>>53762151
Yeah I wasn't asking what would make me better so I'm sorry if it sounded that way. I just didn't know if there was something that ran better/less buggy.
>>53762176void setup () {

f = createFont("OCR A Std", 150, true);

}

text (l[i3], 400, 250);
text (l[i4], 500, 250);
}
It's currently looping too fast, I would like to slow it down
>>53762079
If you really care, concatenating Strings like that is considered bad practice because Strings are immutable in Java (not sure about C#) so you are creating a bunch of objects by doing it. It's not a big deal in this case but just an fyi, try using String Builders/Buffers if you feel you need to concatenate a lot
>>53762203
sleep the thread || lower the frame rate so it calls draw less times per second.
>>53762232
also, i feel like it is really unnecessary typing each action for my integers.
how do i shorten this?int i1 = int(random(l.length));
int i2 = int(random(l.length));
int i3 = int(random(l.length));
int i4 = int(random(l.length));

I'm coming from R and using it to learn Python. It's an agonizingly slow drip-feed of information but I do feel like I'm learning. I'm doing it mainly to get used to the syntax and whatnot.

says the "math is gay" murritard who cannot into calculus
take the sine and cosine functions for example. if you can UNDERSTAND a concise description of them, you DON'T need to grind simple problems for countless hours before you "understand" them. and the pajeet/murritard, after all that repetition, will still lack the understanding to do "more difficult" "word problems". all they learned is to be a monkey that knows how to work a calculator for a very narrow set of problems, completely missing the bigger picture.
>>53761574
>You know that understanding a thing is a matter of memorizing
not only that, you also memorize the RELATIONSHIPS (cause, origin, whatever) that exists between those things

// add char to dictionary

Yeah, it ain't difficult.
