Hi guys, I'm learning Haskell and I have no idea why my fizzbuzz implementation doesn't work?

>>60536817
1)
the input should be integral and showable, i.e.
(Integral a, Show a)
so that you can use mod on it (Integral a) and show(tostring) on it (Show a)
alternatively you could just use Int

2) in the final case, you want "otherwise = show x"
otherwise is simply an alias for "True", what's called the guard (i.e. the clause after |) is simply a boolean

>>60536683
Not as cute as you.

>>60536872
what if i am haskell?

>>60536866
>the input should be integral and showable, i.e.
Why?

>>60536887
(Integral a) indicates at the type level that you can perform "modulo" on a, and that a is a Num (which allows you to, among other things, use literals like 23 as type a)

Show allows you to convert it to a string

Not ALL types can be "mod"-ed, and not all types can be "show"-ed.
(Show <type>, Integral <type>) =>
indicates that these things can be done with <type>
They are constraints, like an interface.

>>60536884
Then you proved that

\existsx[C(x) > C(x)]

and thus that predicate calculus sucks.

>>60536817

 fb :: (String a) => a -> String

this type signature is wrong. As is, it reads "take any type a that is an instance of String, and return a String." However, String is not a typeclass. You want

fb :: (Integral a) => a -> String

which reads "take in any type a which is an integral and return a string

 otherwise x = x 

This will not compile because your function returns a String and an arbitrary integral type is not guaranteed to be of type String. You want

 otherwise x = show x 

and now your type a also needs to be a show, so change your type signature to

fb :: (Integral a, Show a) => a -> String

which reads "take any any type a which is both an Integral and a Show and return a String.

>>60536920
Thanks.

>>60536866
thanks anon I'll try that out!

Haskell is a very interesting language from what I've seen

It's more complicated than Go or Python with regards to the curve

File: constraints.png (3KB, 272x65px) Image search: [Google]

3KB, 272x65px

>>60536920
>>60536887
in fact, if you use GHCI (or an editor plugin that shows you the type), you can look at the type of show and the type of mod
(see pic)

The simplest way of reading these, is:
(Integral a) =>
"Where a satisfies the interface Integral"
If it's a straight forward class like Integral or Show, you might just say
"Where a is showable"

- if you don't know that a is showable, how can you show it?


These constraints have to be satisfied, and traditionally that means they "float up to the top" - i.e., if you call a function that has a (Show a) constraint, then the function calling it normally also has that constraint.

You can make an exception for something like (Show Int), because Haskell trivially knows that there's an instance Show Int. Similarly (Show Double), (Integral Integer), etc.
But when you're writing a generic, you don't necessarily know that, so you must constrain it.

You can also have a 'superclass' of a constraint, i.e.
class Eq a => Ord a

(Ord a) only exists as (Eq a) does
This means if you know (Ord a), then you also know (Eq a)

>>60536955
Alternatively, you could do

 fb :: Integer -> String

and not need to muck around with type classes at all

>>60536408
Is there any point in doing something like

#define MAX [some big number]

char *string;
string = malloc(MAX*sizeof(char));

When I could just

#define MAX [some big number]

char string[MAX];

>>60536989
in the example here >>60536995
Since you're using show and mod, you still need Show and Integral, but since it's

(Show Integer, Integral Integer)
Haskell already knows that they exist, so you needn't put that in something calling fb, for instance.

>>60537006
>

sizeof(char)

Why would you size of a char?

>>60537053
I bet you don't even cast malloc

>>60537006
Yes, if you want to check for failures, if you want to resize it later or if you want to return it from the function that you created it.

I don't want to.

so why cant any """"""""""systems""""""""""""" language actually go down to 1 true bit?

>>60537539
Because basically every computer is byte addressed.

>>60537539
because you sorta can't address bits

>>60537539
Blame the jews

>>60537556
Byte by definition is the smallest addressable unit, so of course every computer will be byte addressed (Even if the byte is not 8 bits long)

What makes Rust better than C++?

>>60537457
I've encountered that in embedded systems class (writing 8051 code in C), but I am not sure it actually adressed 1 bit directly. There was probably some masking involved, since you cannot physically adress anything less than 8 bits (usually).

>>60537566
Sure you can, if Byte = 1 bit

>>60537848
>"""portable""""

>>60537257
and OCaml will have type classes and multicore (eventually). But it doesn't yet, and D still needs GC.

>>60537857
Some assemblers have optimization

>>60537648
By having a decent type system that is good enough to protect you in most situations through static analysis, and requires you to make it obvious when it does not protect you by using the unsafe keyword.

The only places where unsafe is used extensively tends to be in libraries that export heavily optimized data structures. Otherwise, even device drivers will use one unsafe block for every 100 lines, and typically this will be exported from its module as a safe operation by keeping the unsafe operations private.

>>60537847
It's pretty low in the scale of "amount of abstractions it offers. It doesn't even have built-in hash tables, a feature that's pretty standard in modern languages.

>>60537883
There is not scale, it's either (i)abstraction or (ii)native/1-1 correspondence

Why should a library feature like that be a language feature? Fucking retards.

>>60537779
start by designing it. answer basic questions (what's it good at, why does it exist, why should I use it over another language?) and use that to guide you through the design phase. then consider how it works - what paradigm is it? is it garbage collected? what's the type system like? what's in the standard library? syntax should always come last, but develop a temporary syntax and feel free to adjust it constantly.

after finishing the design, it's time to implement it. choose a language to write the implementation in and whether you want to make it a compiler or interpreter. then design a syntax tree (data structure for defining all possible programs as a tree. this should not correspond 1:1 with the syntax, and the less complex the better). once you have an abstract syntax tree (AST) down, youll likely need to write a pretty printer (should be easy) and a lexer+parser (lexer being the part that converts text into groups of characters that represent distinct syntactic forms and the parser being the portion that turns those syntactic forms into the AST); you can do this with either lexer and parser generators (PEGs, ANTLR, Lex/Yacc) or manually (recursive descent or parser combinators). an easy learning project is trying to parse Lisp code.
once the previous steps are complete, implement any features like type checking, macro expansion, preprocessing, template substitution, etc. that occur statically. this really depends on what you're trying to achieve with your language.
finally, it's time to make your language "work". at this stage you're either gonna compile or interpret your code. interpreters are generally easier and can be done in 2 ways: either run the code directly from the AST by recursively descending through the tree or compile it to an intermediate bytecode and then execute the bytecode. for compilers, it's pretty similar to this step of converting to bytecode. you can add optimizations, but that's not necessary.

compiling can be done to various things. the "big boy" way of doing it is compiling to native code (assembly/machine code), but in reality this is more work than you'll need 99% of the time. your best bet is to compile to a lower-level language (like C) or an intermediate language like LLVM IR. both of these will handle lots of the optimizations for you, which is a plus. you can also target a virtual machine (can even be your own), so for example the JVM, which would mean emitting JVM bytecode (or if you're trying to save time, you can just convert directly to Java). if you're trying to get started with this, try to think about how you could translate whole programs to the target language and then try to find patterns for each node in the syntax tree.

Hi guys, I have been working on my first reasonable size CRUD application and it's fun.

Today, however I have an exam in database management. Could anyone give me a quick example of how joins work in SQL? The resources I've found online aren't really helping too much.

Assuming two relations customers and orders

SELECT order_date, order_id FROM
    customers
    JOIN orders
        on customers.customer_id = orders.customer_id
WHERE customer_id = 3

Will return the three specified attributes, will this work if you select from the second table and join on the first?

In fact, in a proper language only functions would be first-class, like lambda calculus does, as everything can be created from them.

Many IETF standards are retarded as fuck. The IETF version of Chacha20 for example (96 bit nonce and 32 bit counter, while the original and XChacha20 have 64 bit counter, limiting the data that can be transferred per nonce. Moreover 96 bit nonce can just barely be used with a random input, thankfully libsodium adopted xchacha20 with a 192 bit nonce).

There is much more bullshit in IETF standards, such as DNT, HOTP, TLS (when we have the much superiour IKE/IPSec or SSH), etc.

You should instead just use algorithms and data structures that are cache friendly and have a good O(x) instead of micro-optimising. Premature optimisation is evil.

>>60538780
Those are more micro optimizations. Actual algorithmic optimization requires careful analysis and sometimes a lot of math.

Know your architecture, it changes all the time. Read the assembler every time, Re-implement a function in asm if the compiler is spiting out garbage code and that function's performance "matters". Use profilers to find slow functions and re-implement.

>>60538855

(^) :: (Num a, Integral b) => a -> b -> a

(Num a, Integral b) => a -> b -> a


Where "a" is a numeric type, and "b" is an integral type,
a -> b -> a
(Given an "a", given a "b", return an "a")

Daily reminder that C can't do this:

>It is easily seen that the only numbers between 0 and 2, including 0 but excluding 2, are 0 and 1. Thus the remainder left by any number on division by 2 is either 0 or 1. Hence the quotient ring Z/2Z, where 2Z is the ideal in Z generated by 2, has only the elements [0] and [1], where these are the images of 0 and 1 under the canonical quotient map. Since [1] must be the unit of this ring, every element of this ring except [0] is a unit, and the ring is a field ...

because parallelism isn't the only thing that influences the performance of an application. a primary factor would be that Elixir runs on a VM. C/C++ also have mature compilers that have been iterated on for decades. i don't know if Elixir implementations utilize JIT, but that would also be a factor. and either way it's worth noting that JIT compilers can actually outdo compiled C/C++ assemblies in some cases because they can make use of assembly extensions known to be present in the system at runtime, while C/C++ compilers can only take advantage of such extensions if they are known or assumed to be present on the target machine at compile time (and if they aren't, the program will simply fail, meaning that most real-world applications are limited in this sense). obviously no VM/JIT language will ever be able to fully match or overtake properly-written C/C++ in terms of performance, but generally speaking the gap has gotten smaller and isn't done shrinking yet

>I'm willing to bet that single threaded C++ is faster than palatalized Elixir programs
this is probably true in a lot of cases, but not wholesale (and it's sure to get better over time; keep in mind that Elixir is a very young language). it would depend on the program and the system running it. an algorithm isn't going to run worse on 16 cores unless the bytecode (and later assembly) generated for the Elixir implementation is like... intentionally bad compared to a canonical (but serial) C++ implementation. that's assuming we're talking about an algorithm that stands to benefit significantly enough from parellelization. some are going to be naturally more bottlenecked than others, even in the best-case scenario

How big of a role does a processors architecture play in terms of how a compiler runs?
With GCC, do the developers of GCC have to port the compiler to different architectures because they have different instruction sets? If I wanted to make a new architecture for example, a embedded microprocessor, would I as the developer have to contribute to GCC to add the specific details for GCC to compile to my instruction set after having designed it?
Or another one would be if I designed my processor to be RISC or CISC, how would GCC compile for both environments when they're quite different? Or do they just ignore that and lose a bit of power for convenience?

shilling occurs on both sides of the political spectrum

>>60541556
are you a displaced Flash developer in denial or something? AS3 is nothing special. it's probably not even the best ECMAScript dialect. you might wanna branch out a little bit

hi /dpt/ what is your favourite JVM?

>>60541824
No, im a forced student who much prefers C and C++, but i come on here to complain during class cause its way too easy and this language sucks.

But thanks for the concideration!

>>60541837
That's like asking "What's your favourite type of dog shit?".
I'm not particularly fond of dog shit.

If your professors are teaching you AS3, they may have brain damage.

>>60541874
Probably, yeah

>variable names that are single letters that aren't iterators in a tight loop

Total shit code

>>60541902
This... Gotta have that extra efficiency because of single letter variable names in tight loops.

i'm pretty sure there's a better way to draw a pixel than doing a full primitive pass of a circle with a radius of one, even in flash

Exceptions are fucking garbage. Only the most vehement of Java OOP street-shitters would defend them.

Ah, there it is. Great argument by the way. Exceptions = BTFO

They're invisible gotos, making your program difficult to reason about.

Why? You gonna back that claim up?

If you're catching them like you should they shouldn't be a problem

>>60542061
Do you put a try-catch block around every statement in your code?

>>60542061
>If you're catching them like you should
I don't use shitlangs so that would be impossible.

>>60542061
>>60542070
this is not actually necessary. in fact that's kind of the point of exceptions and exception-safe code; the idea that you can safely handle errors potentially dozens of nested function calls deep without leaking memory

>>60541902

To be fair, certain letters can make meaningful variable names on their own...

x,y,z = coordinates
w,h,l = dimensions
i,j,k = iterators (as you've mentioned)
n = number of elements
a,b,c = temporaries
f,g,h = callback functions

If there isn't much meaning to a variable's name, it can be given a short name that suggests its type or use within the function, rather than its overall purpose.

>>60542210
>w,h,l = dimensions
i think you mean "d" as in "depth". l/length is better suited for n-dimensional vector magnitude
