ITT discuss Haskell

> Why Haskell?
As a language, Haskell's excellent support for FP allows for performant and extremely concise code. Contrary to popular belief, Haskell can also be used effectively for imperative programming.
As a learning tool, Haskell will force you to become better at FP, which, in most languages, will help you avoid writing verbose imperative code.

lazy evaluation is useful so you can apply optimizations to the lazy ordering of tasks.

Quoted By:

BTW here is a brief introduction to functors, applicatives and monads:

Functors are types that define the operation fmap (<$> in infix form). fmap has the following type and properties:

fmap :: Functor f => (a -> b) -> f a -> f b
fmap id a == a 
fmap (f . g) == fmap f . fmap g

Applicatives are functors that also define the operations 'pure' (which puts something into an applicative) and <*> (sequential application).

These functions have the following types and properties:

pure :: Functor f => a -> f a
(<*>) :: Functor f => f (a -> b) -> f a -> fb
pure id <*> v == v --identity
pure f <*> pure x == pure (f x) --homomorphism
u <*> pure y == pure ($ y) <*> u --interchange
pure (.) <*> u <*> v <*> w == u <*> (v <*> w) --composition

Monads are applicatives that also define a 'join' operation. The monad bind operator >>= can be defined in terms of 'join' and 'pure'.
There is also the monad composition operator >=>. These have the following types, definitions and properties:

join :: Monad m => m (m a) -> m a
(>>=) a b = join $ fmap b a
(>=>) f g = \x -> f x >>= g
pure >=> f = f
f >=> pure = pure
(f >=> g) >=> h = f >=> (g >=> h)

Interestingly enough, monads were added to Haskell before applicatives. Doing an operation using applicative operations is often faster than doing the same operation using monadic operations, so try to use applicative functions.
Functors, applicatives and monads also have some additional operators, but they can all be derived from those covered in this introduction. (An exception is liftA2 for applicatives because some applicatives may define <*> in terms of liftA2 instead of the other way around)
Monads have a 'return' function but it does the exact same thing as 'pure'.
Sorry if I screwed anything up, hope this helps

No, it's not. It's too old to go and live on campus and get piss drunk every weekend with 18yo coeds, but there are plenty of postsecondary programs for working adults. Most masters programs are designed specifically for working adults.

If you don't yet have a bachelor's degree, start taking college classes at your local CC and then consider an online course like https://www.wgu.edu/

Whatever you do, stop making excuses for an arbitrary fucking reason like "I'm too old." You'll always be too old until you decide you're not.

you all talk so much about technology, but you cant talk about hacking because you cant actually do anything. I run a hacked network of computers that I programmed to click on googles ads in my secret website. I even write my own viruses to make people get hacked into my network.
I work at home and have a bunch of screens showing me what people on my network are doing on their screens. I can even set it so that i can see the code of their computers. can you guys do any of that? I dont think so.
I bet you dont know where all the websites real hackers hang out are either? if you name them, I just might tell them that marshviperX sent you.

but Intel is going down the drain because their server processors can't be trusted anymore, or, in the best case scenario and with the patch installed will be 30-50% slower

expect a huuuuuuuge market share shift from Intel to AMD in the enterprise sector
