You should learn Haskell. Some crazy shit (infinite lists! and more!)
>>51908043
In python, easiest way would be to make a dictionary where the keys are words and the values are the count. You check "if key in d" and increment if it is, or set it to 1 if not. Then you print all the keys next to its values
>>51908087
That's basically the C solution too, except you need to write your own dictionary/hash. Good luck!
>>51908065
Keep at it. Realize all the cases of possible inputs and how they alter the output, then canonicalize.
>>51908076
I actually was learning it for about a week, switched to python for the libs and the employability. I had a great deal of fun in that week though and definitely will revisit it soon.
>>51908091
>you need to write your own dictionary/hash
what if i just make an array of char arrays and assign the next token to a new slot if it doesn't strstr match any of the previous strings?
>>51908091
I see, pretty cool then. Couldn't really tell what the haskell code is doing at a quick glance since I've never used it.
Are job interview questions that easy though?
>>51908113
That's slow as fuck if the list of words is long.
>>51908113
Totally depends how many comparisons you plan on doing. If you're processing 10,000,000,000 words, the Python solution with a dictionary will run faster than your array-traversal C solution.
I'd do it your way if i knew I only had to check 20,000 words or so and it was a quick hack for a personal project.
>>51908139

the amount of recursion is actually mind-boggling. I used to think recursion was simple but now I'm not sure.
>>51907968
So don't do it in C. If you want a meaningful C exercise, try making a shell or something. For simple puzzles, just use whatever language you're comfortable hacking shit up in.

Literally 5 minutes of code.
Is there a C SDL tutorial that isn't shit?
>>51908290
It is unless you're fucking terrible.
If you can't whip out a hash table from scratch in a few minutes you need to go back and learn your basic data structures.
>>51908399
No, because SDL is shit. Just write your stuff from scratch. It literally takes about 3 hours to get a multiplatform bitmap renderer up and running.
>>51908413
are people actually like this?
>>51908348
Not GP. I don't think I've written a hashing function since high school.
How do you handle collisions? Do you store the full key along with the data, and jump down the list of collided keys until you hit the exact match?
>>51908467
That's typically how I deal with collisions if I'm lazy, yeah. If you use a good hashing algo (not the one in that guy's post lel) collisions will be quite rare, but even if they happen, traversing 4 or 5 entries of an array to compare keys in the worst case is still an enormous improvement over iterating over half the entries on average. Linear access is a bonus and easy to code. Also typically resizing your hash table isn't as easy as reallocing like that, so there's some more boilerplate.
>>51908220
klib's khash it literally just a single .h file, and it's released under the MIT license.
>>51908459
There is literally no reason to use SDL. I'm working on my third game engine right now. Coding the platform-specific (input, window management, sound, threading) bullshit took me less than a day. Prepping my OpenGL environment took maybe 3 hours... and now I have pretty much everything SDL would've provided me. Hardly a waste of time, especially because of how easily I can dive in and tear things out if I don't like the way I implemented them.

>JavaShit
>>51908105
It seemed memeish the shit people said about Haskell, that it'd make you a better programmer and all that shit, but in my case it has.
The only issue is when I found out a functional implementation sometimes runs -much- worse than the imperative way in some languages(optimization issues.) But the functional way is almost always much clearer at first glance for me now.
>>51908546
Linux/Windows. I don't have OSX to compile on, but I doubt it would take more than 2 hours to port.
No idea about mobile. Never programmed for them, never will. Seems to me if you're planning on making a mobile app you should design it for mobile ground-up instead of half-assedly porting something designed for desktop/laptop.
>>51908556
Weak typing. Hoisting WHILE using functional scope(it seems insane because it is, and causes a ton of bugs with novice programmers.)
>>51908539
You know you can static link libraries too, right? Not that it's always the wisest move. On Windows, static linking all of the things is acceptable, because there's no working package manager, so you're going to be distributing all of the dependencies with your application any way you slice it. On Linux though, there's no reason not to take advantage of the space and memory saved by using dynamic linking. And yes, memory is saved. If two applications use the same dynamic library, both can access that library's functions via shared memory.
>>51907915
>cats
You are sick
>>51908556
It's super-fucky. It has really powerful capabilities, but to be honest nobody really even realized that until the 2010s. It's a mix of weirdo ideas and fucky behaviors.
Also, optional semicolons. What the fuck. Fucking retarded. I'm convinced it was a passive-aggressive move by a programmer whose coworkers kept putting opening curlies on a new line.
>>51908608
This is only a problem if your libraries are retardedly bloated. Nobody needs 300MB+ libraries. If libraries were more specialized and less monolithic, dynamic linking would be absolutely useless.
>>51908615
How do optional semicolons prevent you from doing that anyway?
>>51908662
Because it inserts them like some kind of retarded fucking program.
http://robertnyman.com/2008/10/16/beware-of-javascript-semicolon-insertion/
>>51908645
Even if it's only a small amount of memory saved, why waste the disk space on static linking, or the network bandwidth on distributing statically linked applications? Linux already has the infrastructure for making it easy to distribute dynamic libraries into standardized locations, and therefore the use of static linking is more or less useless on this platform.
>>51908690
OK, but what if a program depends on a library's older version that has inconsistent behavior with the newer version?
With static linking this isn't an issue. With dynamic linking, your package manager needs to store every version of every library forever.
People are awful at programming. Libraries will have bugs. Programmers will rely on those bugs. It is inevitable.
If people were good programmers and followed good practice, then I agree, dynamic linking might be "ideal", but I don't think the world works like that. Including all the code you need for your program to work properly is always going to be the safest course of action.

>>51908690
>Even if it's only a small amount of memory saved, why waste the disk space on static linking
I don't know about libraries on Linux, but dynamic libraries on Windows are a huge pain in the ass. Disk space, memory, and bandwidth are all increasing like crazy. I mean, fuck, the *average* webpage now is bigger than pretty much any Win32 binary package I've ever shipped.
So, yeah, I'd much rather take the maybe 200KB penalty versus having software that doesn't run.
>>51908728
Doesn't Linux have smart dynamic linking, where you can have versioned libraries on the same machine?
Basically, what Windows did with manifests and their super sneaky fake file-system trickery?
>>51908734
If you're stringing together >>= like that, why not just use do notation? And you can move createDict to be another thing in the following composition, because you are doing nothing but applying it. So something likedo
[x] <- getArgs
y <- readFile x
mapM_ print . M.toList . createDict $ y
You could also merge the last two lines toreadFile x >>= mapM_ print . M.toList . createDict
I think this is nicer than chaining >>=, unless you are doing it for learning purposes. If you are, you could still move createDict to the compositions
>>51908728
In that case, use static linking.
In the general case, just always use the latest, most bleeding edge version of any given library.
>>51908734
>>>= \y -> return (createDict y)
This is equivalent to map createDict y. I agree with the other anon that createDict should be moved to the mapM_ block.
>>51908879
But the point was that I might write this code with a bleeding-edge version of a library, and I dynamically link it. Now I have to expend time and effort making sure it always works with newer versions of the library. If I statically link, then I know for a fact it just werks.

>>51908973
GLEW is fairly clunky. You need to tell it whether you'll be linking against the static or dynamic library (via GLEW_STATIC). And you need to check whether your system actually supports a feature, otherwise you'll just get a segfault when you call a null function pointer. It won't magically add features which your hardware/driver doesn't support (and if your driver installation is borked, you get Window's built-in software-only OpenGL 1.1 implementation).
For some extensions on some drivers, you may need to set glewExperimental=1. That causes it to not bother checking whether the driver reports the extension as supported; it just retrieves the function pointer regardless (some drivers don't report all of the extensions they actually support).

Unless you sign over your rights to the code, meaning you get 0 credit for it, you can still let the next company know what you've done and use that. If you write code in one place and then never see it again, you might just be cucking yourself.

There's no need for the first for loop.
Also, substitutes new line characters with spaces so it doesn't accidentally join words:import re
words = re.sub('[^A-Za-z\'\s]', '', re.sub('\n', ' ' open(sys.argv[0], 'r').read().lower()).split(' '))
uniqueWords = [ list(set(words)) ]
for i in range(1,len(uniqueWords)):
uniqueWords[i].append(words.count(uniqueWords[i][0]))
print uniqueWords[i][0] + ' ' + uniqueWords[i][1]
>>51910455
And I forgot to include the shortened stuff at the end:import re
words = re.sub('[^A-Za-z\'\s]', '', re.sub('\n', ' ' open(sys.argv[0], 'r').read().lower()).split(' '))
for uniqueWord in list(set(words)):
print uniqueWord + ' ' + words.count(uniqueWord)
>>51910485
The split should be outside of re.sub():import re
words = re.sub('[^A-Za-z\'\s]', '', re.sub('\n', ' ' open(sys.argv[0], 'r').read().lower())).split(' ')
for uniqueWord in list(set(words)):
print uniqueWord + ' ' + words.count(uniqueWord)

Should I look into getting into github? I'm an EE undergrad right now, my main purpose right now is to use it to deal probably with programming assignments etc for now.

Programming languages are designed to be turing complete. Asking if they are is pointless. Meanwhile, a more interesting question is whether Magic: The Gathering is. MTG was not designed to be turing complete, and yet we already have models using certain cards to simulate a turing machine if certain voluntary actions are taken whenever they are allowed to be taken. This is not quite ideal given the fact that the game's rules require any infinite loop to be terminated at some point (specified by the user) if the user has the option to do so (and the game is forcibly terminated in a draw if the user cannot). However, given the flexibility of many of the cards, and the increasing number of different cards that add new rulings being introduced into circulation, I'm certainly positive that at some point someone will create a combination of cards that will trigger an undecidable game. That is, where a combination of triggered abilities (without "may" clauses) will create a complex series of loops that no turing machine will ever be able to decide if the game should end in a tie, or if at some point, the game will reach a final state, and that the game can continue on from that point.

um, not that what I'm about to ask matters to me beyond a measure of curiosity, but do you think that the game you just described would be treated as the high point of the game. Meaning, would it be the S++ tier level of the game's meta-interaction or just the point of absolution in the matter of turing completeness?
Btw, have you ever heard of high level Street Fighter 3: 3rd Strike play? I like to think that with parry being a staple action in the meta that it could possibly be turing complete. Maybe not between all the characters but certainly between one's that can force motions and a distance between characters. Maybe those with 1 frame recoveries or mode activators like Yun who can force an opponent to block or red parry and then cancel in either early enough to block or activate late enough that the opponent's actions are swallowed up by the system garbage collector forcing a stalemate.
I have always wanted to learn MtG but the few people I know that play the game are snobby about the play or just clouded in that they don't offer up much besides a linear transition between modalities.

You don't need to share with anyone but you should use git nonetheless because
* Remote backups
* Version history
* Branches to work on multiple features at a time without cluttering your code
* Submodules for deps
* Easier collaboration if you ever wanted someone to join your project
* Bisecting
* Applying patches from a codebase you base on & keeping the original relevant commit messages

Because then no one will see it. Barring the possibility that you failed to supply any code in an interview or through an email before you got the interview, there is also the whole social media aspect to the thing. People want to work with people they would find pleasant or people they can at least be assured have a sense of social-ness that they adhere to. No one wants to work with divas in a team environment. Primadonnas make everything for themselves. If you can interact amongst others and adhere to a CoC then they can be sure you can get the job done and not slow down the company by refusing to help your fellow team mates or by refusing their help on a matter.
Still, that's not saying you can't just make a quick website with your portfolio on it. It's not like you're being cased on your ability to design pretty things, but rather functional code.
Ultimately, git is just flickr for coders is just blogger for photographers is just youtube for writers is just deviantart for videographers is just etc for artists. It fits well into the coprorate structure and is likely easy to "parse" as such.

It's the least structured form. Think of it as an unordered list and then other more corporate uses of python as an ordered ( sorted ) list.
You learn the same thing, pretty much anyway, but blackhat follows a less particular procedure that amounts to more of an interaction with an existing system, whereas the other forms are creating a structure and then defining pathways about that structure. Blackhat can interact in this one too but would be doing so at the leisure of the structured method, which is arguably a bit more "esoteric" in its phrasing of things.
Basically, blackhat would keep it recreational and the structured one would be corporate or scholastic.
>>51911311
>inb4 learn Haskell

I understand now. The only thing I need to know now is does blackhat covers the basics of the language or it jumps immediately in some work expecting you to catch those basics that are shown implicitly ?

>but do you think that the game you just described would be treated as the high point of the game. Meaning, would it be the S++ tier level of the game's meta-interaction or just the point of absolution in the matter of turing completeness?
I'm not entirely sure what you're going on about. What it would mean in theory is that it is impossible for anyone to be able to forecast if a game would end in a tie or not. In practice, some of the cards used in these combos would just flat out be banned, and thus the situation would only ever come up in casual play.
>Btw, have you ever heard of high level Street Fighter 3: 3rd Strike play?
I don't really play street fighter. The only 2d fighter game I've ever found myself really enjoying (other than of course, the Super Smash Bros series, which isn't really a traditional 2d fighter game) is the Bloody Roar series. And I haven't played that in ages. Also, I have no idea how you intend to simulate a turing machine using parries unless you can literally gain arbitrary code execution with it.
>I have always wanted to learn MtG but the few people I know that play the game are snobby about the play or just clouded in that they don't offer up much besides a linear transition between modalities.
Don't bother. The game sucks now. The only decks I ever seem to hear about these days are aggro and sometimes mill decks, depending on the set. Legacy and Vintage play is almost non-existent, and if you do play it, you pretty much have to have thousands of dollars for either power 9 cards and/or force of will/other cards that can stop fast combos. Plus, they've simplified a number of concepts. It used to be that combat damage between creatures was placed on the same stack as everything else, so you could respond to damage by, say, sacrificing the creature.
>"Hard realtime" video games
>>51911440
It doesn't force the theory wrapper on you and instead offers you a chance to posit your own construition about the concept of the thing you're learning. Both will be presented as a matter of you interfacing with the "problem". "Blackhat" will present itself as a manner of approaching the problem with less than the narrow line of "this coding now, programming later" and instead will allow you to see the code as simply a path to the understanding of the problem. If you write to a buffer, it will show you what you wrote into the buffer and the container that holds the buffer data. In the more structured form, you'll simply be concerned with having spelled out everything correctly and asserting that you have done the correct thing.
I would like to say that both give you the basics, as you already know the basics ( numbers, letters, phrases, yes and no ) but beyond that when dealing with things like functions, classes and, arguably, things oddly named as tuples, you might not be versed and it will just kind of course through the matter. That doesn't mean you can't just reference the material, but it does mean that you can expect to "take to the material" as others have.
Sometimes I'll read someone here talk about a tuple as if it were some amazing thing worth mentioning, but then follow the code and see that all they did was make a program that should normally process characters also manage to process a tuple, which is just a set that has the same number of elements as the name implies.
YOU CAN SKIP TO HERE IF DONT WANT READ
Having said all that, sorry if I said too much above, you probably won't expected to know all that stuff implicityly. I think I remember a violent python book going over each of the items rather extensively and redundantly but that was the same reason I couldn't finish it. Then again that was a while back when I was in a more hectic environment.
Still, the high point, I think, in programming is that implicit sense.
I'm writing something in C and it's not working well, so I need a debugger (for Linux). I need it to be able to display variables and stuff like that, and (ideally) to display a tree-like structure without it looking horrible.
I've tried using DDD, but it's a buggy clunky mess that looks bad. It did its job pretty well when I had patience for its shit, so something similar to DDD but of higher quality would work for me.
Any suggestions?

Btw, never mention the word blackhat around regular cs babbys. They will conform to a weapon concept over you. Especially the asian ones. And now that there are vapes everywhere, it'll be more difficult for them to get caught. Unless you can match the smells.
If you need a more formal approach to the basics, you're better off just trying to learn it via a few programming theory cheat sheets. It's not that difficult.
The electricity travels around the board and activates the different components, which then either continue their calculations, traversals or light up for the screen. Each pass brings with it information from the registers which are found in the processor. Each pass can also gather information from the different peripherals tied to the motherboard. After that it's just sending the writer numberic signal or alpha-numeric signal to either activate a register, calculate some sequence or traverse an array in memory.
After that it's abstraction as some concept you already might understand. None of this stuff is something you don't or can't already know.
>>51911467
Ahh thanks for the clarification on the card use.
> Also, I have no idea how you intend to simulate a turing machine using parries unless you can literally gain arbitrary code execution with it.
Bingo, that's exactly what it does. A very deep part of the game is managing to make the parry work against the other player. That's actually my forte. :) If it helps you understand a bit, the game is coded in ASM and runs 60fps which is never throttled but made less apparent by display hardware. I'm one of those CRT dudes.
And that's too bad to hear about MtG. I actually love Tactics style play. Made me a little sad to hear they removed that from the battle conversation.

I don't really want to repeat myself on the whole deal because someone died there, and probably from the same kind of vape attack ( his heart just suddenly stopped ) so I'm not about to tempt the fates by giving you enough info to follow me around.

Vapes are lasers. Overload one and the laser gets bigger. Overload a lot of them and the laser can go farther. Hold a laser in place long enough and over a soft enough material and it can burn that thing. I have a bald spot on my head.
It's not a fun topic to share because there's lots of strawman stuff out there to make me come off like a loon just for being not white/asian/black and having been a victim to groups of people, MILLIONS, but...ultimately the damage is there and it's not like I go around taking part in rumbles or fights in the street. The timing was right, there were some warnings made, some cautionery statements and ultimately the tools were made more prevalent.
Actually, they could've hid WPT coils in the vape pens too. Some of them were military personnel, some move satellites ( doubt it was him/them ), some are just sadistic psychos with caste issues. I'm not trying to convince you, just elaborating on the topic for dude up there that needs to understand the difference between blackhat and otherwise, "as seen from above".

Was just interested chum. Stay safe out there.
>>51912226
It has to do with the word "Blackhat". I have never used it to describe myself but I also don't take to labeling myself. Others, rely entirely on labels and can't very well manage with pronouns and such. Often times, when people find themselves confused or "out of the loop" they act erratically. So while learning Blackhat Python might be a simpler approach to a grand design/problem, a regular structured python that abides each and every convention like a P = NP problem in quantum theory as described by convention he might find himself in less than a heap of trouble by just going that route, though he might not feel like he's learning anything because none of it amounts to much beyond the next course, which will likely go over a lot of the same material just through a different convention.

is it good practice for a parent class have a method stub that will not be elaborated on in the child class? Or is there a better way? Wikipedia says that method stubs are usually only used for testing.
e.g. this pseudocode:class Parent {
int x;
...
public void update() {
//Does nothing
}
...
}
...
Class child extends Parent {
...
public void update() {
/*Each child method does something,
but the parent method does nothing */
x +=1;
}
...
}
...
class Program {
int main() {
for( Parent parent : object ) {
object.update()
}
}
}
Is there a better way? I'm still learning.
>>51912359
*that will be elaborated on when overridden in the child class
>>51912359
I believe the parent class then is an abstract class. The fact that you would be declaring the function in the child class but not the parent class means that you find it necessary to communicate the essential nature of the function, probably based on the design, so I would say that making the abstract class would be the way to go.

uh, one pixel even 1 off will change the whole hash, so yes they're unreliable.
Simply even resaving the jpg image will produce a different hash.
You need to store the image, not the hash, and then compare the differences between 2 images, and decide sameness with a threshold.
>>51912488
So it just makes it difficult to make the proper positives you mean...I thought you were saying it makes for more false positives by not averaging to the proper hash. My mistake.
I was thinking that the make up of a 64x64 hash that is equal measures black and white vertically would hash out the same as a picture that was rescaled to 64x64 and happen to also have equal measures of black and white vertically even if one of the pixels on the white side had a tiny bit of black on it from artifacts. That's surprising.

How difficult is manually drawing on screen?
Thats also some awfully philosophical approach to something that utillitarian in nature, in your case atleast.
Do prefer music as white noise personally, but I guess that could work too.

Not difficult if you develop proper tools for it. Something like Photoshops pen tool is usually all one would need to help with that. At that point it's not different from using a paint program and then bringing in the pixel info so if you have a good one, just use that and don't kill yourself trying to code the pen tool, though I know GIMP is open-source and that has a pen tool. Also, I use the shape functions a lot too. After that it's like grade school with all the pasting and cutting.

Interesting concept, but the issue is that any reasonable person who can see that a series of actions are repeating themselves without possibility of player intervention will call the game a tie, due to an infinite loop.
