I have an enum, and I want to create a Dictionary, with each value of the enum being a key to a double initialized to 1.
Do all four variations accomplish this? Is there some subtle difference between them I need to be aware of? What is the point of Enum.ToObject if I can just cast?var eValues = Enum.GetValues(typeof(FooEnum));
Dictionary<FooEnum, double> bar;
// 1.

You could argue that there should be another check in case the mode isn't 2 but the final else still triggers.
I could account for that, but the switch doesn't even have a default so I really don't give a shit.

>>53542947
Or use >>53542830
No need for a switch at all.
It only requires one more compare, but it's a 0 check so it's relatively cheap.
I've also prioritised the check for gloop_ret so if you've had to make that function call you can short-circuit with the second 0-check (well half the time).
If gloop_ret is more likely to be 0 then simply reorder the conditions to be (!gloop_ret || mode == 2) res = barf(); else res = arf();
Also it should just return from the conditions, not set result and then return after, although this is probably optimised out anyway.

What's the most optimal way of rendering a textured heightmap in opengl where the textures may be different from tile to tile?
I'm currently splitting my heightmap down into regions and rendering those regions seperately through a VBO, but it's definitely feels slow.
>>53543159
You have 2 possible calls, arfle() or barfle(), so neither method is going to pipeline very well.
In fact if you are concerned with being predictable, then you should call gloop() whether you need the return or not, then make the "switch" constant time for all cases.
Thinking about learning a litttle bit of assembly. Should I learn 32 bit, then move on to 64 bit or just start with 64 bit? Should I use a different architecture, like MIPS? Anyone got some good links?
Thanks anons
Any reason to why this isn't finding my file?conf = "file.conf"
for root, dirs, files in os.walk('root'):
print "searching", root
if conf in files:
print "found: " + join(root, conf)
It doesn't find my file for some reason, I'm looking to avoid hard coding because this file may exist anywhere.
I'm on Linux if that helps
>>53543451
It's worth mentioning that it doesn't print "searching", or anything for that matter. Doesn't break or print an error message
What else should I add?: http://anonlabs.byethost10.com/
>>53543451
'root' is not a directory
os.walk("/")
>>53543503
I can't believe that, I re-wrote this code numerous times because I didn't use '\'.
Offhand, do you know how to make it return only the first match?
Because at the moment, its printing several and the only way I know is by breaking it, but if you break it then you can't use the value elsewhere.
>>53543443
32-bit runs on everything anyway. 64-bit is really just 32 with bolts added on, so you'll need 32 to understand 64.
Also MIPS is a world away from x86, not a lot is transferable really, so just learn whatever you think will actually be useful.
Not just in a "this is kinda cool" way, but actually useful. If you are going the micro route, I would suggest PIC over MIPS.
There are educational architectures like SAYEH if you just want to learn the theory but they are pretty useless in the real world.
>>53543443
A lot of universities teach their basic asm course using Patterson and Hennessy's 'Computer Organization and Design: The Hardware/Software Interface', which uses MIPS. MIPS has a very simple instruction set and it would probably be the best place to start just to get used to how registers, etc. work.
If you learn something like the latest intel instruction set you may be introducing yourself to too much complexity and making things harder.
>>53543691
This. You will learn the newfangled instructions when you need them.
>>53543587string firstmatch = ""
conf = "file.conf"
for root, dirs, files in os.walk('/'):
print "searching", root
if conf in files:
firstmatch = "found: " + join(root, conf)
print(firstmatch)
something like that

Using a texture array would be a good place to start. It would allow you to coalesce all the geometry together, and more importantly save on expensive texture binds.

Hey /g/
I started taking a C++ course this semester. It's basically been the professor lecturing by reading off these powerpoints that are basically notes for the reading assignments.
Every week we have this lil quiz online that asks us about simple concepts that were in the notes/reading assignment. Before every class meeting we have to turn in some homework that is writing this small program in microsoft visual studio, and then including a screenshot of our program working and our code.
So after the professor reads his notes to everyone we take a break and then start our "lab" portion of the class which has been strictly programming the mindstorms lego robot using Bricx and doing some NXC codes so that we can get our lego robot to do something like follow a line of tape on the floor.
The thing about this is that the professor gives us little direction and we basically have to figure everything out on our own, including writing the programs for the homework.
>TLDR
How do I teach myself other than reading a book and being confused in class every day?
I'm not a computer engineer/computer science but this is a required course for my major that involves C++ but we do little to no actual C++ practice in class. Even the professor says he doesnt like the way the course is being implemented.

Of course, but it's still a bit more overhead. It kinda depends on what >>53543443 wants to learn. IMO reading Computer Organisation and Design and learning MIPS would be better if he wants to learn all of the details of how processors work at a low level, while using the assembly to facilitate that exploration. In addition to less instructions, it also has fixed length instructions, which may make things easier to grok.
If he just wants to learn some random assembly language for the hell of it, it doesn't really matter what he chooses.

Call me old fashioned but I think everyone should start out with a low level, strongly typed language, because it will teach you some things about computers that if you don't know will lead you to write terrible code and because for beginners, weak typing can encourage some bad habits, habits I have made a career out of correcting. Plus working with a compiler will put some hair on your chest rather than an interpreter.
It won't matter if you just want to do it in your moms basement, but if you ever get out in the field and have to work with a million-line Java project, with 100's of people (mostly morons) working on it, you'll be a lot better off and your coworkers won't hate you

tempaltes are much more powerfull than preprocessor could ever be. Templates are not only a turing complete functional pattern matching language, but also beautiful code generation tool.

any way to approach this?
i already solved for the normal knapsack 0/1, my solution keeps adding items with the same id...

Why are you searching for the player instead of storing the position with the rest of the player data? Presumably you have a player struct or class that holds all of the player info, and it should include the player location.
Also, are you verifying that the move location is a valid one before you move there?

haha

if the maximum weigth was 12 i would chose the items:

1---1---4
how do you find the greatest value/weight ratio here?

I'm trying to make a pig latin translator in python, because Codecademy's PygLatin section only works properly on words that start with consonants.
Here's what I have so far:def pyglatin():
original = raw_input("Enter a word: ")
s = original.lower()
vowel = ["a", "e", "i", "o", "u"]
consonant_word = s[1:] + s[0] + 'ay'
vowel_word = s + 'yay'
if len(original) > 0 and original.isalpha() and s[0] = vowel:
print vowel_word
elif if len(original) > 0 and original.isalpha() and s[0] != vowel:
print consonant_word
else:
print 'Input contains a non-alphabetical character.'
pyglatin()
pyglatin()
What needs to change?
>>53545563
Well using that example, value/weight ratios would have done the job perfectly.
It will work better the higher W is in relation to the individual item weights.
It's not exhaustive, and may well not always find the optimal solution, but it's much faster than bruteforcing.
If you had to find the absolute best option, then you could at least sort the permutations somewhat by the ratios so you get a good answer quicker.
The problem there is how do you know you have the best answer until you've finished every possible one, you'd need a threshold like 95% of w minimum or whatever.

If you are running this as a script you need anif __name__ == "__main__"

>>53545944
are you this retarded? have you ever written anything in your life except fizzbuzz?
why can't i use standard library cin with cstdlib getline? if i use it even once in my program, getline instantly returns 0 (or EOF or something, i haven't actually explicitly tested its output) at eveyr call. i've tried flushing the stdin after every cin but ended up just having to rewrite everything in my program to use cin.getline instead because i'm working with C-strings.

to answer my own question, evidently cin leaves a newline char in the buffer after you use it. i still don't understand why clear(stdin) and fflush(stdin) don't work
>>53545969
>2016
>still unaware of overflow
/g/ everyone!
>>53546039
if fflush(stdin) is the same as c, it's only defined for output not input so if you use it for input it may or may not work
>>53546015
Overflow is not something that applies here, dumb shit.
>>53546061
i think the implication is that you're not going to be using the function for any data type which is larger than sizeof(int). it wouldn't be very hard to alter it for more portability
why is everyone always so invested in the idea that the person they are talking to is an idiot?
>>53546068
please tell me you have an actual mental illness
>>53546099
>data type which is larger than sizeof(int)
Do you even know what overflow is? It has nothing to do with sizeof(int), dip!
>>53546109
there are some different applications of the concept "overflow" in computing. you're probably going to have to be more specific
>>53546123
>be more specific
Look at the code, you shit!
>>53546147
the only overflow issue i can see is when you try to cast a larger datatype to int and to operations on it, but if there's something we're all missing, by all means please elaborate. but unless you want to stop shitposting and say something substantial, this'll probably be the last bit of attention i'm going to give you.
>>53546123
>>53546174
Do you see how the "concept" of function in the shown code uses the "concept" of subtracting 2 signed integers? The "concept" of overflow in the result triggers the "concept" of undefined behavior.

If I wanted to overload a << operator to print a set, how would I do so? Each set contains a room, where a room is defined to be a contain a short int roomNumber(n), short int capacity(c), and short occupants(oc). Occupants is a list of names. While we're at it, how do I implement this set? Studying for a test on c++, could use some pointers. http://csiflabs.cs.ucdavis.edu/~ssdavis/40/Final%20Handout%202.pdf

>>53546947
Make already knows how to compile a .o from a .c, you don't need to specify any of that. Just replace the entire makefile with:vm: main.o chipset.o mmu.o processor.o disk_hub.o pic.o pit.o
You don't need .h files on the vm rule, linking only depends on object files. And the .h stuff shouldn't be manually done:
https://www.gnu.org/software/make/manual/html_node/Automatic-Prerequisites.html
It will use gcc to generate rules for your headers and include them. Or just use GNU autotools.

Use -j with (num_of_cores * 2) + 1, i.e. if you have a quadcore CPU:
make -j9

alias mj="make -j9"

Something to do with a job for each thread, plus one for every hyperthread (x2), and then one ready to go as soon as the next job finished.
If you just want to compile as fast as possible, even if that makes your system near unresponsive, just use make -j and it'll work out the jobs for you.
