That's just how the results happened to end up on the TIOBE index. It's really just a indicator on how much people search for information and resources on said languages.

Scheme / Clisp have the advantage of simpler syntax and less fussing about with harder to understand concepts (Monads / Comonads are hard for programmers to pickup at first).

All of them will teach functional programming. The debate is which is "Better".

Haskell is for "Purity"

Lisp / Scheme is for "Simple".

Technically if you want to actually be practical you're better with off with Clojure / Scala so you can abuse the large ass java code base.

Thank you. I always hear about how Python or C are the best "begginner" languages, but I started reading Structure and Interpretation of Computer Programs and it's talking about Lisp Scheme. Figured asking you cunts would be a good idea.

>>55754643

Lisp: Minimal Syntax, everything is a list or a primitive. All operations are basically (function (data) ) in various forms.

Haskell: strong static typing, purity is very serious, you have to explicitly deal with data flow, there is plenty of syntax to get started with ( -> , :: , (), [], =>, etc). Monads show up from the very first hello world program.

Literally the only reason to say Lisp or Scheme dialects are harder than haskell is the learning curve on getting used to all the braces.

Class *pointer; or Class* pointer;? I know it's functionally the same, but which is better?

>>55754772
Haskell is simpler, maybe not to write proper Haskell but certainly to use.
You can easily use Haskell imperatively if you really wanted to

You don't need to know Monads to print Hello World

>>55754816
t. Haslel cuck

>>55754796
I prefer the former because it more closely expresses how the language interprets the statement.

>>55754796
if there's more than one use *pointer
otherwise use class*

>>55754321
Nice to see C# goin down baby

>>55754903
To be replaced by Python, Javascript & VB.NET?
Fuck off

>>55754816

You're heavily invested in the haskell mindset.

We're basically arguing if green is a better color than blue :p

Both accomplish similar goals when learned. It's pretty much down to thinking patterns / learning methods which is "better" or "simpler".

>>55754322
Can i have the sauce code for this program?

>>55754985

>>55754620

Racket. It even has an sicp #lang so you can have perfect compatibility with the stuff they use in the book.

>>55754985
main = print "Hello World!"

(begin (display "Hello, World!") (newline))

>>55754985
LISP/Scheme encourage and allow and forgive sloppy thinking. It's like teaching someone Python as their first language, they get stuck on it because they think other, less forgiving languages are 'too hard'.

The course i am enrolling next fall in college (3 years total) has this courses :

> Algebra
> Mathematical Analysis I
> Discrete Math
> Python Programming
> Computer Architecture (intro to assembly, low level theory..)

> Computer Architecture II (assembly, FPGAs, low level stuff..)
> Mathematical Analysis II
> Statistics
> C Programming
> Physics

> Introduction to networks
> Java Programming
> Operative Systems (C language)
> Computation Theory (automata, state machines,...)
> Information theory (entropy, compression,security,...)

> Introducton to Algorithms
> Data Analysis and Transformation
> Multimedia (Actionscript, javascript games)
> Communication Protocols (advanced network stuff)

> Databases (SQL, Java, Oracle, Mysql, Postegres)
> Software Engineering
> Distributed Systems (Java, websockets)

> Computer graphics (C, C++)
> Compilers (C)
> Artificial Inteligence (Python, C#)
> Advanced Algorithms (C, C++)

So my question is:

Can i be called a Software Engineer after i complete this course?


Or, what's the appropriate title in this case?

I know this has some Computer Science courses, so i'm a little confused

Hey, newbie idiot here. I ran across some decent video tutorials for a python machine-learning library used for stock analysis and it seems like a neat idea for a project. If I were to write a stock trading program, assuming it isn't shit, for a beginner anyway (I'm not new to the math and the algorithms I'd be using are simple enough that they shouldn't cause me too much pain to implement), could I somewhat reliably make a bit of income? Nothing even close to serious, I'm not that stupid. My ambition lies somewhere in the 10$ a month on average range. The reason I care that it makes money isn't because I'm jerk off at the thought of ten extra dollars a month, but it would make the project less rewarding if the outcome was 100% useless.

If you're talking text adventure style sure.

A actual rpg engine is a pretty complex project. Stat systems, equipment / inventory management, menu drawing / interaction, a file format for saving / loading games, some sort of flag system for events, tiling graphics, enemy / npc scripting, and tools for editing them all.

As for the vm it depends on what you define as a the minimal requirements. A chip8 emulator itself is just implementing a old vm to specs.

I care immensely. The python way is just fucking retarded

if_true conditional if_false

is just retarded in so many ways.
It doesn't start with a conditional, so at a glance, if_true looks like normal code that will execute every time.
The conditional is between code, obscuring that it's there.
The ways you visually parse it is stupid.

second if first else third

compared to the much more sane, left-ro-right

first ? second : third

            array[0] -= 32;
            for(pos; pos>0; --pos)

_Bool has different semantics than an ordinary integer type. Why not important in this particular example, it's something you should know about.
Also the triviality of the header's implementation is not important.
