All jokes aside, the Android SDK and ecosystem is in a pretty bad shape. Minor version bumps in Android/Google libraries break applications. Android Studio keeps getting better, but it's far from a professional tool. The activity/fragment lifecycle is a pain to work with. Especially Samsung devices give you very low heap size to work with, so I've seen numerous OutOfMemoryExceptions. My main occupation is video playback. I've yet to see a player implementation fully work on modern devices. ExoPlayer is getting there, but it has some rough edges. For DRM, I usually turn off hardware decoding and run everything on software. Since that gives you performance issues, I remove HD+ bitrates.
There're a lot of Android events I can attend, so that's always cool. I don't really participate in the community, because most of the focus is on design. I don't like writing UI stuff.
So it's OK I guess. It's a hell of a lot better than being a web dev. Also, iOS is just as broken but fanboys cover that shit up.

"Impure" functions that use monads like IO in Haskell are pure functions that return computations. These computations are then composed using the monad structure. Haskell can be seen in this way as a DSL for composing programs that do things. The other way to look at it is that linearity (through monads, in Haskell) preserves purity even with the presence of side effects that affect the world serially, since you have to explicitly sequence them so that lazy evaluation (a "perk" of purity) can't mess things up. If the linear world becomes an argument to and result of the function, by definition you can't call the function twice with the same arguments to get a different result, so purity isn't violated.
What is your definition of purity? If it's "no side effects under any circumstances" where "side effect" means modifying memory, doing I/O, etc. at all then you're wrong. Because if you model the computer's memory as an array, and have a function like this, it's pure, but apparently also has a side effect:write :: a -> Pointer a -> Heap -> Heap
>>52073293
I personally write comments before I write the code, so I can better keep track of what I'm about to write, and in case I jump around in the code to write different pieces of methods.
Also, the method isn't very complex. I believe the reason for why I'm doing it is rather understandable (if you see the rest of the code).

Not him, but it's unfortunate that in programming "function" has generally been bastardized to mean "an abstraction of a subroutine".
Those should be called procedures, while a function is kept in line with the mathematical sense of the word.

But they tend to alter state elsewhere. I don't know if the mathematical definition of a function allows that

it's not homework. i dont study CS, im planning on hooking up the python server on a raspberry pi to an outdoor light, because my mum has to walk the muddy path to our door in the dark, so i want an internet connected light she can toggle with her phone.
literally whats wpf good for?
>>52073819
So, in your words:
T = unit -> T = T
and this somehow means that a value of T is a function.
Are you the same guy who constantly shills F# and thinks that purity means no touching memory/filesystem/etc.? You should really get yourself down off of the peak of Mount Stupid.
>>52073839
>And for the same input(s) it will always produce the same output.
What about rand()? No input (input is unit/void) but it always produces a different output.

Rand doesn't always produce a different output. It produces a predetermined sequence of outputs based on the input seed. Also the ol' rand() is deprecated.
>>52073871
>What about rand()? No input (input is unit/void) but it always produces a different output.
Rand takes a seed from the current timestamp. That timestamp is an input to the function. The same timestamp will always produce the same rand() which, combined with the same input to the function calling it, results in the same output for those inputs

why
>>52073904
It's output is dependent on the state of external variables. a function, I think, has identity.
what's the best c++ compiler in terms of optimisations and also running on linux?
>>52073896
Church encoding is just that, an encoding. Not the essence of everything.
>>52073904
That doesn't change anything. Even if it just produced 0,1,0,1,0,1... it wouldn't be a mapping from inputs to outputs, and thus it is not a function.
>>52073922
>Rand takes a seed from the current timestamp.
Wrong.
>That timestamp is an input to the function.
Wrong again. Well, the seed is an implicit input, but mathematical functions don't have implicit inputs.
Anyone else have a problem with codeeval's Reverse Words problem?
my output is correct but it fails me every time, I even checked it against a diff utility and reading it myself line by line.
A pure function is surjective.
Any input is mapped to only one output.

>>52074001
you mean it isn't multivalued
>>52073987
Is it all the letters reversed too?
>>52074001
A surjection is a total function. Any mathematical function is pure.
>>52074025
That, again, has nothing to do with purity.
>>52074025
he means if input x results in output 1, x will always output 1. If input x outputs 1,2,3 it will alwys output 1,2,3. An array/tuple/ist is still a single output.

The difference between a function and a relation is only meaningful if you're confining yourself to grade-school maths where everything deals with real numbers and functions of real numbers and nothing else. Is the square root a relation where the domain is the set of real numbers or a function where the domain is the set of pairs of complex numbers?
>>52074162
I guess you could argue that under univalence, values are equal to functions because they are equivalent to (can be encoded as) functions. But it's kind of a useless tautology to say that "values are functions" in that case, because that doesn't make them not something else at the same time.
I'm working on a LSB steg encoder/decoder in C#.
You can encode and decode hidden text/files
The only problem I have right now is trimming off the excess bytes from the embedded file when its being decoded. My MIN recognizer finds it even with all the crap at the end.
Tell me what you think, I'm sort of new to C#, so any advice or comments are appreciated :)

Makes it easier for people downloading so they can just run it instead of compiling in Visual Studio. At least that's what my thought process was. That exe isnt updated fyi

People who use github and are interested in your project are going to tinker with the code and compile it themselves.

The repo should contain just the source code, documentation and build project (VS project in your case). Just put a link to the binaries in your readme.

im learning a bit more about reading values from a programs memory and sort of reverse engineer shit, and i want to call an internal function
i've launched the program in a debugger and i do a breakpoint to what would atleast be close to what function i'd want to call and i sort of have some c# code ready to call the function, but navigating through the assembly is pretty hard, and there's probably 20 CALLs and i can't really guess how the structure of the program works by the assignments along with the fact i'm not entirely well versed in assembly
is there an easier way to do this and i'm overlooking something, or should i just spend more time to try and understand this

GitHub's text editor Atom is programmed in CoffeeScript and uses WebKit for rendering. It would be a great text editor if it weren't slow as shit.
Made this bit by following some example, but what's the purpose of the "x2"? if i check the hash i get online it matches with results, but if i change the "x2" no longer will it match. is it supposed to be an option or something?private void buttonX1_Click(object sender, EventArgs e){
string a = textBoxX1.Text;
SHA1 crypt = new SHA1CryptoServiceProvider();
byte[] bth = Encoding.ASCII.GetBytes(a);
bth = crypt.ComputeHash(bth);
string b;
foreach(byte by in bth){
b += by.ToString("x2");
}
b.Trim();
textBoxX2.Text = b;
