visual studio
>>51883618
You don't need an IDE to compile stuff.
Look up mingw.
>>51883618
I'd recommend learning how to use makefiles and compiling directly from Gvim.
I also believe that there are plugins for Notepad++ and Atom that let you compile things directly from the editor.
If you really don't want to give those a try, you could try CodeBlocks, but I remember it being a pain in the ass when I began coding.

well, you could create a function that takes 3 items into account:

Yeah I'm working with just the batting average of the batter and the average of batters faced of the pitcher and using odds ratio for now, going to try to expand it over time. Probably better to start small and expand it over time.

What is a 'reduce by key'?// sparse histogram using reduce_by_key

void sparse_histogram(const Vector1& input, Vector2& histogram_values,
Vector3& histogram_counts) {
typedef typename Vector1::value_type ValueType; // input value type
typedef typename Vector3::value_type IndexType; // histogram index type
// copy input data (could be skipped if input is allowed to be modified)
thrust::device_vector<ValueType> data(input);
// print the initial data
print_vector("initial data", data);
// sort data to bring equal elements together
thrust::sort(data.begin(), data.end());
// print the sorted data
print_vector("sorted data", data);
// number of histogram bins is equal to number of unique values (assumes
// data.size() > 0)
IndexType num_bins = thrust::inner_product(
data.begin(), data.end() - 1, data.begin() + 1, IndexType(1),
thrust::plus<IndexType>(), thrust::not_equal_to<ValueType>());
// resize histogram storage
histogram_values.resize(num_bins);
histogram_counts.resize(num_bins);
// compact find the end of each bin of values
thrust::reduce_by_key(data.begin(), data.end(),

I was trained to use cout << / cin >> on C++.
How does that stack up with printf() instead?
Does it matter if it's in C?
>>51885691
printf is significantly better in pretty much every way.
>>51885740
Geeze, really? I need to git gud then. Does it require a library like cin/out or is it base?
And what's the printf equivalent of cin>>[variable]?
>>51885848
>Geeze, really?
It's a lot faster (no virtual function shit) and is easier to internationalise.
>Does it require a library like cin/out or is it base?
printf is a part of the C standard library. Every (hosted) C program has access to all of those functions.
>And what's the printf equivalent of cin>>[variable]?
The scanf family of functions.

I am looking at it right now. But having a quick summary is always nice. Plus it keeps the conversation going. Kindly fuck off.
More Cstruct Table(float orient){
float Mercury=orient*.38
float Venus=orient*.904
float Mars=orient*.376
float Jupiter=orient*2.538
float Saturn=orient*1.065
float Uranus=orient*.886
float Neptune=orient*1.14
float Pluto=orient*.063
float Haumea=orient*.064
};
//below...
struct Table(orient) Planet;
The goal is to be able to call for the numbers by having a line such asprintf("You would weigh %d %d\n", Planet.Mercury, str1); //str1 is the units.
But I'm pretty sure I am declaring the structure wrong. Or some other equally elementary problem.
>>51886919
>%d %d\n"
%d %s\n"
>>51886919

use %f, likeprintf("You would weigh %f %s\n", Planet.Mercury, str1); //str1 is the units.
>>51887032
jajaja, I caught the belatedly. Still, there seems to be some problem with declaring and instantiating the structure.
I assume it has to do with me trying to pass in a value (orient) to the structure, but what's the deal? How would I do that differently?

Any way to use Qt on Windows without installing QtCreator? I'm perfectly happy with my set up and don't want to use an IDE.
I'm trying to become self-taught in CS, at least until I can get into a decent school. Learning languages is easy, but I'd like to get more theory. Would something like an AP Comp Sci AB/BC book be alright? I know it's not quite at a college level, but I figured it would be more of an overview, and in the meantime I could find books that cover topics more in depth (TAOCP, CLRS, etc)
Or should I just go straight for CLRS?
Also, anyone have any recommended books on data structures?
>>51888109
there might be a minimal installer/package on the qt website with just the "barebones" tools. i'm pretty sure all you need is qmake and a compiler
>>51888201
CLRS is much beyond AP CS.
making a text adventure in python because am nub
>>51888326
About what level would you say it is?
I know C++ and Java. I want to start developing for Android.
What are the esential prerequisites for coding for Android?
Apart from java for the application itself.
What frameworks should I learn?
>>51888705
APCS is pointless bullshit Java shit like inheritance and encapsulation and basic logic and recursion, and you have to memorize some sorting algorithms and binary search.
CLRS is actual algorithms, understanding them and understand the math running time (O notation etc). I only read the first few chapters and it was already much above the entire APCS curriculum I took a while back. Besides, the AP teaches a language (Java, which is shit btw) and CLRS teaches algorithms through pseudocode

why I said it would be best to learn C first but oh well
>>51892795
C is in the other extreme of simple. choose the sensible middle ground with java, C# or C++.
>>51892765
anon, types are not fundamental to programming. python is now the most favored programming language for teaching due to its simplicity, multi paradigm, and pseudo code syntax.

>>51892838
Personally, I tried to learn Python first, but I hated every moment of it. Then I was taught Java in my first couple of programming classes and nearly quit.
Years later, I "discovered" C and fell in love immediately with the control it offered me. It felt like I really understood every step of the process. I picked up assembly not much later.
Now I've been programming in C for 7 years. Still can't stomach Python.

How do I detect when a thread has been updated in JavaScript, /dpt/?
>>51892927
Store the previous thread. Get new thread. Compare to previous thread. If different, it updated.

>Understanding how the CPU works is essential to being a good programmer.
lel
>>51892927
you mean like a 4chan thread? there should be something in the API for that
>>51892949
It is though. If you have no understanding of the hardware you're working on, you're worse than a code monkey.
To you, the computer is something you type magical spells into, and magic comes out. To someone who understands the CPU, it's a marvel of human engineering.
What's the easiest way to send email via python?
>>51892965
all you really need is a rough idea of how expensive a given computation is and how variables get fetched (very slowly) in batches from memory
>>51892965
programming is not about machines in first place.
>>51892784
i could translate it to C, but i can't tell you what it's meant to do, but that has nothing to do with the language
but understanding the syntax etc. and being able to write simple stuff in assembly really isn't that hard if you're proficient in 1 programming language already
>>51892794
wat
wat does that have to do with python?
>>51893025
the implication is that most python users only work with very simple programs/scripts so that they never use big numbers
>>51893013
Code monkey detected.
>>51893085
yeah dude, i am a code monkey, tony hoar is a code monkey, dijkstra is a code monkey, leslie lamport is a code monkey, anyone who have risen himself above the irrelevant machine details is a code monkey.

It's too bad the world doesn't run on theories, it runs on engineering. Computer science without a focus on hardware is useless.

>>51893220
Kek, I bet you're one of those guys who graduates a CS program without ever writing a line of code. But you know algorithms and data structures and what a turing machine is, so the code is irrelevant, right?
>>51893236
>turing machine
>machine
disgusting. i prefer lambda calculus, it's more pure.
>>51893220
yeah
because guess what, it's not about writing assembly programs
its about understanding how things work deep down
>>51893255
>virtual architecture
>how things work deep down
so he sould start with assembly or even jaba byte code, amiright ?
>>51893246
agreed, gotta love myself some lambdas

>>51893268
it's close enough to real world architecture(or was at the time, anyway)
>>51893268
The entire point was that there was quite a variety of popular computer architectures at the time, so he combined the various featuresets and designed a languag which could easily be translated into any of them.
>>51893305
you are confusing programming with computer engineering.

Either it wads a lit or you were not listening. I doubt you'll be getting same results when you run your program one more time.
