What are you working on, /g/?
first for this is your industry now
Why is Python so shit?
Did you know that Guido never read the SICP?
Did you know that Python has no TCO, because Guido thinks recursion is not basic to programming: >http://neopythonic.blogspot.de/2009/04/tail-recursion-elimination.html
Did you see the hack he proposed as "just as elegant" if you want TCO:
>http://neopythonic.blogspot.de/2009/04/final-words-on-tail-calls.html
Did you know that Python has no multi-expression lambdas because Guido didn't know how to extend the whitespace-based syntax of Python to nicely include them?
>http://www.artima.com/weblogs/viewpost.jsp?thread=147358
Why would you defend a language which doesn't have a feature as elementary as multi-expression lambdas because the creator could not figure out how to make them fit?
Why would you defend a language which makes higher order functions almost useless and actively discourages functional style programming, since you don't have multi-expression-lambdas?
Why would you defend a language of which creator doesn't understand the importance of TCO?

Why is tail call so vital to your notion of expressivity? On the contrary, I find that it is an implicit thing that, while being nicer in simple cases (muh babby's first recursive function), will inevitably bite you in the ass without warning in production run. Seriously: asserting that things like lazy-evaluation or trampolining cause exactly the behavior you intend is fuzzy as fuck. Better be explicit like Clojure, no?

It's vital because it allows me to use recursion without worrying about the stack overflowing. Knowing when the compiler chooses to do TCO is dead simple, so I don't see how it would "inevitably bite me in the ass".

>It's vital because it allows me to use recursion without worrying about the stack overflowing.
No it does not. It's trivial to use a trampoline if it's the kind of state you want to have. Or just mark a call as needing to reuse the stack frame, or whatever. I understand continuations and what not, but I really don't see a need besides Wittgenstein-level clever as-simple-as-possible useless kludges honestly.
> Knowing when the compiler chooses to do TCO is dead simple, so I don't see how it would "inevitably bite me in the ass".
I think I encountered something, but I can't remember clearly. Shucks for backing up arguments, yeah. Still, you admit that you and I alike mentally do the steps before writing to ensure that this exact syntactic construct we are using has tail-recursion here and here and there, so why not be explicit? The compiler can't read neither comments nor minds...

https://en.wikipedia.org/wiki/Exclusive_or
the trick i did here is to have two different arrays: one for input (players choices)
and one for the output (the outcome).
for examples, x ^ y always equals 0 if x equals y so "draw" must be at index 0 in the output array.
now, if you say that, in the input array, paper is at index 1 and rock is at index 2, then
the value of 1 ^ 2 must be the index of the correct outcome in the output array.
1 ^ 2 = 3 and paper beats rock therefore "paper" must be at index 3 of the output array.
we now haveinput = {
0: unused
1: paper
2: rock
3: scissor
}
ouput = {
0: "draw"
1: unused
2: unused
3: "paper"
}
keep filling the output array for all possible choices

It's one of the most common optimizations in regard to recursion, so I'd argue it does. I also don't get why you're talking about stack frame reuse and trampolining. Both are often used in implementing TCO, but I can't understand the point you're trying to make. Are you saying you'd use these techniques directly, instead of letting the compiler transform your code?
>I think I encountered something, but I can't remember clearly. Shucks for backing up arguments, yeah.

You're acting like TCO is something the compiler decides through deeply esoteric means. I can understand that you like how explicit Clojure there is, and I don't think you're wrong. But I do believe you're going a bit overboard with your distrust of the compiler. Of course we have a mental model of the process our code will invoke, and in my experience modeling tail-recursion isn't especially difficult, nor error-prone.
Hey guise. Pretty new to programming here and I have a question.
I want to make a program that takes continuous screen shots and adds any newly captured content to the bottom of the image.
For example, say I run this program while browsing this thread. I would take a screen shot starting at the top of the thread and then, the program would continue to take screenshots, adding to the overall picture as I scroll down the page.
The result would be one very large screenshot containing the entire thread.
I know there's already addons to do this for webpages but I want to do something similar outside of a browser.
Can some one point me in the right direction and how I might go about doing this in a Linux environment?
Hey pro/g/rammers. I have a question/problem. I don't want you to solve it for me, I just want you to estimate how hard it would be to solve it and what tool would be the best for it.
Scenario: I have two windows open, one is Chrome, the other has to be Internet Explorer (latest version, but not Edge). In the Chrome window I have information such as : Name, Last name, Address ,etc.
I want to extract the info from the Chrome tab, and then go to the IE and in the IE it should autofill the data that was collected in the Chrome tab.
I am trying to automate something at work. Laziness is the mother of invention they say, and I think it would be a great learning project for the future. How hard is this to do ? How would you do it?
I was thinking of making a Chrome extension, but then I have to use IE for filling the data...
Another way is to use something like AutoHotKey (?) but I don't want to use that, I would rather do it with a proper language to learn something useful.

What you want when writing in Racket (which I do) is for a recursive function or chain thereof to yield an O(1) stack space computation because of tail-position. I think I always have to have in mind the tail-positions of every Racket construct in order to achieve this goal, which I'm not sure I like doing. I'll keep meditating on that I guess.
>You're acting like TCO is something the compiler decides through deeply esoteric means. I can understand that you like how explicit Clojure there is, and I don't think you're wrong.

Of course we have a mental model of the process our code will invoke, and in my experience modeling tail-recursion isn't especially difficult, nor error-prone.
I see where you're coming from. In fact, TCO pretty much follows the flow of results of evaluation, so it's acceptable in my eyes. I'll try going overboard for a while, then I'll come here to report I guess.
Yes surely I'm exagerating...
>>54104544
>https://github.com/eSenpai/rock_paper_scissors/blob/master/main.c
There's no reason to have "rock", "paper", or "scissors" be strings as a choice. They can be an enum. Same with your gamestate.
This allows them to be switched thru which will make your code much more simple.
the checkSelection can be reduced into simpler code. no need for the 3 branches each with 3 branches.
remove srand from randomSelection and place it in main. you only need to generate your seed once. I know you are only calling randomSelection once, but this kind of error can trip you up later once you program sufficiently complicated things.
your first printf can be a simple puts call instead.
your second printf should be written so that the static parts of the string are in the format string. it is nigh unreadable.
use underscores instead of camelcase.
looks good for a starter C program. good job.
I'm thinking about learning python. What do you think about this language?

>>54105763
python is good because you can extend it if you know C. and you do.
>>54105763
it's easy, practical, object oriented, well supported and has a tonne of documentation and libraries.
its performance is also satisfactory for 99.9% of thing you'd need it for.
it does have a lot of less pleasing things: obscene operator overloading, a persistent schism between version 2 and 3 and a shitload of "features" used to trim down code size that you'll have to learn in order to understand it.

So basically:
- write a chrome extension to collect data
- write a simple nodejs server with a DB
- chrome extension stores the data
- write an add on or something in internet explorer that collects the data from the nodejs server / db and autofills the data
I'm especially confused about that last step, I'm not sure how it is in IE
>>54103838
you have to work through the drudgery but it goes away. once you've done it enough it really does become second nature.
however, if you advertise yourself as an expert at something and are constantly resorting to stackoverflow, the "forums", or whatever else in the middle of your work then you aren't an expert at all.
if you aren't seeing an improvement in the time you put in (i.e. you're not getting fast) then perhaps you aren't really challenging yourself or really don't care that much anymore.
>>54105819
python isn't an object oriented language
>>54105867
your node server can just provide a REST interface or a text page with the data in a suitable formet ex. JSON/XML which the IE extension will load and use to fill out the form.
Should be pretty standard functionality that I'm sure IE provides in their API.

Yeah, but isn't it too hard for someone that never programmed?
>>54106069
depending on your background
if you feel confident then you can start with java since it isn't really low level/advanced anyway
but nobody got hurt by spending ~3-6 months starting out with python and then proceeding, you'll know an additional language to compare java to, that way.
>>54106118
programming isn't difficult bro
>>54106118
java isn't hard man and it's probably the most documented language. there's plenty of beginner guides out there.
>>54106118
just start and if you feel overwhelmed then go python.
>>54106077
But javascript lacks inheritance, right?
>>54106118
No way. Tons of colleges use Java for intro to programming.
>>54106151
>But javascript lacks inheritance, right?
it doesn't
>>54106118
How do you think people get started? Nobody is born knowing how to write software.
How does cout print char arrays?
Does it increment a pointer and print each index?
>>54106127
>>54106142
>>54106147
>>54106151
Guess I'll start with java, since I can't wait to get a decent job.
Thanks, guys.

i'm a different guy, cutie pie
I suck at programming can't even make a qt app
Made autofocus for my camera so I can click anywhere on the screen to make if focus on that point in the scene. Pretty neat. Very simple in the end (scale = focal length / intersection depth) but it made me scratch my head for quite a while.
>>54106069
If you want to learn how to ride a bicycle, you don't spend hours agonizing over which one will make the process easier.
You just make sure it's a regular, run-of-the-mill bike (Java, Python, C#, C++) and then you start practicing.

An anonymous function is just that, a function without a name. A lambda expression is an anonymous function, which captures the scope it was created in. This is handy because you can do stuff like this:(define (make-counter)
(let ((n! 0)) ; scope our lambda is defined in.
(lambda ()
(set! n! (+ n! 1)) ; access of captured scope (changing it is local to the lambda, of course)
n!)))
(define c (make-counter))
(c)
>1
(c)
>2
(c)
>3

Hey guise, been playing around with JavaScript and it's fun. Is JavaScript a bad idea for first language?
Can someone explain if I have downs
Bash script herefor ((count=1; count<=${resultsonpage}; count++))
do
func "$anothervar" "$1"
if [ "$count" == "$resultsonpage" ]
then
count=1
break
else
:
fi
done
func is another function, when I change it to echo it ouputs the right output but when I change it to the function it doesn't get the first var or $1 from the first function.
I can't wait for mass genocide guys

Thanks Ruby friend. This might be kinda general to other langugaes too..
My idea is... say I have a very large project. And when i compile, I want to avoid the entire project being compiled each time. Instead, I break it up into assemblies/dlls and have a very small exe project that references all of them.
Now each time I compiler is should only recompile the small exe project and the dll projects I changed.
Maybe this shit is hyper obvious, but I've only started considering it recently.
Is there a way to get the first character from a line that is output from a command in bash?
e.g.:$ command | grep thing
0 thing 1234
^$
I want to get that 0 in a bash script. Any ideas? I've never done much bash. Is it something likec = $(cut-c-1 `command | grep thing`)
Or something?

Whats the best way to change code you've copied so that you don't get caught?
my prof runs it through some program from Stanford that compares similarity to other students' code, sort of like TurnItIn but for code.
Ik i shouldn't heart etc but I had no time to do this program and this is my only option lol
Hey /dpt/
If I wanted to learn a new language only to change the way I thought about programming, what would you recommend? I do most of my work in python and js and it's not very theoretically interesting.

What do you mean by "type of element"? Do you mean it's actual type (ie bool or int)?

In Java you can check the type witharr[i] instanceof MyClassType
C doesn't have type information at run time, so you can't check.

If you compile with debug symbols then GCC and Clang have typeof macros.

i knowinstanceofbut say you get the first element of ClassType in the list then you want to compare a variable from it with the variable of the next instance of ClassType in the list

then you cast it to the ClassType and do whatever you like.if (arr[i] instanceof MyClassType) {

Overcomplicated design that OOP zealots say is "good".
Claims to "encapsulate" something but actually is wide open.
Inconsistent code style.

That I can agree

Maybe you are just stupid, but it doesn't claim to encapsulate anything
>>54108379
his point was that if you compile with debug symbols then GCC and Clang have typeof macros. What's confusing you?
>>54108398
>Will my 16GB of RAM be enough for making a desktop game with Unreal Engine 4?
yes
>What's the fastest way to learn C?
by not considering learning C, it's obsolete and useless in the context of UE
>>54108398
the fastest way to learn C is not by learning UE4, but by going through K&R2. Even then, good luck with C and UE4.
>>54108416
>Maybe you are just stupid, but it doesn't claim to encapsulate anything
Why on earth would you have getters and setters then?
>>54108398
Congrats. The stupidest question to be asked so far. 16gb ram is a meme, and C doesn't have anything to do with UE4.
>>54108421
His point is not-standard pig disgusting.
>>54108431
>>54108441
>>54108452
I'm taking a course that requires C. It isn't related to UE4 at all.

Tip top fucking kek
I have to write something in C++ for class, and I haven't used C++ before, so I'm trying to learn as I go.
I have 20 classes which inherit from 1 class, and each of those 20 classes will need a method call foo() which takes the same arguments and returns the same type.
If I do something likevirtual int foo(int, int_t, int_t_t);
in the 1 class that every class inherits from, do I have to create a foo() function prototype in each of those 20 classes?
>>54108520
>>cheat on every assignment without being a retard about it
heh, irony. got it
>>54107947
I swear to god!!! /g/ code always looks ugly as shit!

Read K&R, assuming you already know how to program.
>>54108543
K&R is almost 30 years old.
>>54108534
assuming it is not pure function, no
>>54108555
your point?
>>54108555
And is still a good book. It teaches C (C89 specifically) and does a good job of it.
Even if his networking course uses a later C version (which I doubt), K&R still teaches you like 90% of what you need to know.
>>54108536
Doing work that can be avoided is for cucks
>>54108581
>learning what you paid a small fortune to learn makes you a cuck
>>54108555
Everything in that book still applies in 2016.
You can even use the suggested compiler cc, it redirects to GCC on most systems.
>>54105913
yeah it is
>>54108593
half the code in the book won't compile in newer standards
>>54108625
bullshit
The code from the ANSI C K&R compiles fine. It's standardized, you know.
>>54108571
>>54108578
>>54108593
Wow, I triggered some turbo autism.
K&R 2nd Edition was published in 1988, so it predates C89, so it can't even be used as a guide to write shitty MSVC C programs. I want C11, the latest standard.
I bought a new book for 40 CAD and plan on using it. I was more asking about techniques to learn C instead of just pointing me towards a dusty old tome.
>>54108648
>Wow, I triggered some turbo autism.
No, you were wrong.
>>54108640
>ANSI C
as I said, won't compile in newer standards
>>54108648
>K&R 2nd Edition was published in 1988, so it predates C89, so it can't even be used as a guide to write shitty MSVC C programs
Kerrigian and Ritchie were involved in the C standardisation, you know. They knew what was going to be in the standard.
>>54108537
you rewrite that function then. Maybe I'll learn something :)!
>>54108670
No, you're still wrong.
Show me some code from the second edition of K&R that won't compile under a modern compiler, please.
