You obviously don't understand the CS grad thing.
That was a problem definition for people to implement.
The CS grad would be mixed with all the retards failing to understand it.
I want to write a program which does some processing of audio. By processing, I mean things like finding tempo.
Does anyone know of any resources that goes more into this sort of stuff? I already know about samples, sampling rates and whatnot, but I don't know how to actually process the data.

Is there a better way to compare strings than strncmp?
>>54844603

>>54844626
This just checks if 2 strings point to the same location in memory.
>>54844791

>>54844862
This doesn't compare strings, you should rename it is_aliased()
>>54844862
it doesn't do what strcmp does
>>54844882
it does compare strings, it just doesn't compare them the way you want it to
>>54844937
When people say 'compare strings', they mean compare it's contents, not it's location in memory.

How does strcmp work anyway?
In the man page it says:DESCRIPTION
The strcmp() function compares the two strings s1 and s2. It returns an integer less than, equal to, or greater than zero if s1 is found, respectively, to be less than, to match, or be greater than s2.
But I when I compare my buffer with the text "PING" it returns 0 even though the buffer does not exactly match the string constant.
makefiles are a pain in the dick
i just want to dev
>>54845118
use scheme
>>54845105
If they match exactly, the return value is 0.
Most people use !strcmp(...) instead of strcmp(...) == 0
I don't know why it's like that, when none of the other C library functions return 0 to mean "SUCCESS".
>>54845154
because it's also telling you whether it's before or after it alphabetically
>>54844543
Fuck, this is pissing me off. I know what these underlying "types" are and how they're stored in memory, but I just can't figure well enough to not feel as though the language and available tools are getting in the way of making the machine do what I want it to.
Fuck "C-style" strings. I'm by no means in a frame of life conducive to learning anything new, but this is going to drive me to madness. I'll have to become something else to make this happen, and I will stay up for three days straight until I can cram this whole fucked up framework into my head.
Pro-tip, it's often said sleep is vital for memory, but this isn't strictly the case nor does it apply uniformly to all aspects of memory. Near the 22-26 hour mark, if caffeine is supplemented, it greatly enhances fluidity of thought, abstract connections, and memorization. Sucks, but it's true, and it works.
It begins. Goodbye /g/.
>>54845193
I find a lot of people have difficult with C until they come to the realization that everything in C is an abstraction built on pointers.
That being said, there's nothing wrong with C strings.
They're about as minimal and effective as it gets.
It's just an array.
>>54845585
>there's nothing wrong with C strings
They're the source of many bugs, though.
>>54845154
>Most people use !strcmp(...) instead of strcmp(...) == 0
I find it to be the opposite exactly. !strcmp really doesn't get across the meaning of that test.
>I don't know why it's like that, when none of the other C library functions return 0 to mean "SUCCESS".
It's doing a comparison. Strings can be 'less than' or 'greater than' another, and <0 and >0 are used to show that respectively.
>>54845154
But say I have char *buffer1 = "kek", *buffer2 = "kokkek";
Why does strncmp return 0 if the strings are not exactly equal?
>>54845643int strncmp(const char *s1, const char *s2, size_t n);
Are you passing in 1 for the 3rd argument?
>>54844335
If you're rolling your own argparser in C++ then you have fucked up my friend.
>>54845643
>strncmp
Because strncmp will only test up to n characters, so you're really only testing a substring.#include <stdio.h>
#include <string.h>
int main()
{
char *str1 = "kek";
char *str2 = "kekkok";
printf("%d\n", strcmp(str1, str2));
printf("%d\n", strncmp(str1, str2, strlen(str1)));
printf("%d\n", strncmp(str1, str2, strlen(str2)));
}
The first and third print a number less than zero and the second prints 0.
>>54845705
post your code
>>54843111
quite cool
>>54845585
I know. I'm just having difficulty manipulating or accessing more or less anything the way I want. ie, here's the code as it is now.struct Runtime_State Options;
std::vector<std::string> files;
for (uint8_t count=1; count<argc; ++count)
{
if (!strcmp(argv[count], "--help")) {help(); return 1;}
if (!strcmp(argv[count], "--evaluate")) {Options.evaluate = true; continue;}
if (!strcmp(argv[count], "--input"))
{
++count;
while (count<argc)
{
if (strncmp(argv[count], "--", 2))
{
++Options.file_count;
files.resize(Options.file_count);
//files[Options.file_count] = argv[count];
++count;
}
else {break;}
}
break;
}
std::cout << "Unknown option \"" << argv[count] << "\"";
return -1;
}
The problem is entirely the one line I commented out. What in the fucking fuck is wrong here? It compiles fine and then throws a segmentation fault. Why can't it just take the bytes out of the specified array element, and put it into a vector of std::strings? Do whatever padding etc it needs to. It has all the information it needs, the space has been allocated, so fucking do it. I'd dig through the library and find why it can't if I thought I'd readily understand any of it.

The tools you will need are things like:

I'm getting very sick of Google as well. The unfortunate nature of capitalism is that anyone can eventually do whatever moronic nonsense they want, as long as they have the economic to make it happen. The latest is their "project loon", ie, a massive floating mesh network aimed at undercutting existing service providers without having to compete in controlling, renting, or laying underlying infrastructure. Though obviously it could have... other uses, over time. The main problem with this? They're primarily held up by helium balloons, the minority are hydrogen. What a waste.

As someone who's only ever done OOP languages, I didn't quite grasp what's so bad about them from the article linked in the video's description. I get that sometimes people go overboard with creating unnecessary classes for everything, which can make the code bloated and confusing, but why should I prefer to use fukken goto-statements and global variables over a handful of classes with defined statusses and behaviors?
>>54849144
don't worry it's just memes and strawman arguments
>>54849144
OOP potentiates cache misses, memory fragmentation, and often encourages organizing control flow such that you end up dicking around instead of just doing what you wanted to do. This becomes cognitive overhead, ironically.
OOP principles are fine, but an insistence on strict adherence to the "pure" philosophy is demonstrably negative. Like I said, humans might like OOP, the machine often does not.

Join subject as t3 on t2.subjectid =t3.subjectid
innerjoin string as t41 on t1.nameid = t41.nameid
innerjoin string as t42 on t3.nameid = t41.nameid

As long as one doesn't use strictly abstract reasoning, and both bears in mind and engineers their abstractions for, the real world mechanics of their target machinery, controlling state via interfaces with conceptual objects is fine.
As I said though, a lot of the calls people end up doing to influence objects, or cause them to interact, are not easily inlineable, and the required data (because that's what an object is actually composed of) likely won't be contiguous in memory and cannot be accessed on serial cache lines. Worse, people have a tendency to like to make the cpu chase around pointers everywhere, which also results in cache misses.
Hybrid styles are ultimately the most efficient. A lot of the philosophy, cognitive psychology, etc really is superfluous. I see people generating false dilemmas for themselves all the time around the whole "object" notion. The only relevant aspects are not writing yourself into a corner, and the fact that relative to any task, a given system has an intrinsic maximum capacity for efficiency. Identifying the means, and then approximating this within reason is the ideal. Not neatly making false objects.

Depends on what your goals are with them. If it's just to do things more efficiently just learn to make a single producer multiple consumer queue.

For some reason I thought the previous stacks were growing upwards and then this one started and was growing downwards. Never mind.
>>54850856
Did your programmer heroes ever do drugs? No. They were too busy programming.
>>54850856
Most and none.
Really depends on individual physiology, psychology, starting state, and your general frame of life. Any altered state, even if it doesn't advantageously change how your brain is functioning relative to a given task, can afford a useful new perspective.
My ability to make connections and realize better solutions to problems, and code some great things, has been improved while drunk, high on cocoa beans, full of caffeine, phenibut (which I generally don't like) etc. By the same note it could do the inverse. It could be functionally null.
Large spectrum of factors involved. The best advice is to learn to do things with drugs, rather than do something while they're doing something to you.

Modafinil is pretty good, but then again it and all the 'study drugs' work well for any intensive task. Then again mostly use it for my uni programming which is pretty braindead.

Not that poster, but this just strikes me as so amusing.
For my entire life I've referred to people as "them" or "they", and caught quite a lot of flak for it. That's incorrect they said, why are you speaking so strangely, why are you using plurals. Because it strips unnecessary embedded assumptions, can be resolved implicitly, and works even when you don't have information.
Now days I get to watch you people, because it's all about the gender neutral pronouns. It's all about how gendered words are the last remaining flaw of the English language, and how it's spillover from our germanic and romance language roots.
Yep. You fucks are only ever two+ decades behind, but they always come around, eventually.
>>54851506
Still wrong, if you are a SJW, it's "He or She"
I use he since I'm not a cuck

Why aren't you using monads?
>>54852388
b-b-but I'm using the Free monad...
also ignore the pragma's, had them from earlier memeing.
>>54843719
Invalid.
++i++ is same as ++(i++) but the standard requires the operand of the unary++ to be a modifiable l-value but the postfix++ returns an r-value.
>>54852408
Not good enough
>>54851036
That's a pretty specific field.
That kind of software does have good odcumentation and certification courses. If you're serioud I'd suggest investing in a cert.
>>54852454
The free monad is the memeiest of all monads.
>>54852521
show (return n >>= Fizz >>= Buzz)
Would be nicer code.
Type would be
t * [s]
Where [s] is the labels and t is the labelled value
Bind gives the value and adds labels of the returned function
(Either keep the old value or use the new one)

Pythonfag here, running a silhouette analysis on my k-means clustered data. I have a bunch of vectors and for every one I have to calculate an AI (the average distance between that vector and other vectors within the same cluster) and a BI (the lowest average distance to all vectors from another cluster).
Here's part of the code:for cluster,clusterNumber in zip(clusterDict.values(),range(len(clusterDict))):
aiList = []
for vector1 in cluster:
listOfDistancesAI = []
for vector2 in cluster:
distanceAI = silhouetteDistance(vector1,vector2)
listOfDistancesAI.append(distanceAI)
averageDistanceAI = sum(listOfDistancesAI)/len(listOfDistancesAI)
aiList.append(averageDistanceAI)
biList = []
for vector, clusterNumber in zip(cluster,range(len(clusterDict))):
clusterDistanceList = []
for otherCluster in clusterDict.values():
listOfDistancesBI = []
for vector2 in otherCluster:
distanceBI = silhouetteDistance(vector,vector2)
listOfDistancesBI.append(distanceBI)
averageDistanceBI = sum(listOfDistancesBI)/len(listOfDistancesBI)
clusterDistanceList.append(averageDistanceBI)
clusterDistanceList[clusterNumber] = 10**100
biList.append(min(clusterDistanceList)
The vectors are fed from a dictionary which has a key for every cluster and then a list of vectors as values. The problem is, the AI values are getting calculated just fine, but its only calculating 9 BI values. The amount of vectors in the cluster should match the number of AI and BI values. The biList.append statement is in the for-loop for the vectors, so it should be appending as many BI values as there are vectors.
As it happens, 9 is the amount of clusters I'm telling my k-means algorithm to make, so stuff might be in the wrong loop?

Read up on cache thrashing, atomic operations, and concurrent data structures,
Remember that the ideal implementation of multithreading is lock-free.
Also remember that its possible to get more than one writer by distributing or mirroring the dataset.
There are many academic papers on this subject as well.

Not a DSL, also your interpreter is completely tied up.
>>54852841
Value: and Categories: are just labels that can be used in the constructor but are just there for the StructuredFormatDisplay (to make it print differently)
The type is just
categorised v c = v * [c]
(I should probably reverse this so it makes more sense 'type currying', and makes the bind's signature more obvious)
a Seq is a lazy list in F#
The
let bind f (Categorised(value, categories)) is a pattern match (total in 1 case) that decomposes the argument into the identifiers value and categories, i.e. it's actually
let bind f m = match m with | Categorised(value, categories) -> ...
>>54852898
?
>>54852898
>>54852901
Also
a { ... } is a computation expression, 99% of the time it's just do notation (but a is an object and so it can be parametrised on an object)
let! x = y // in a cexpr is just // x <- y // which calls a.Bind(monad,function)
return! is normally just id, it calls ReturnFrom
return calls Return
Why is my shit always blood stained whenever I try a dildo?
>>54852973
It means there is still hope for you.
More comments edition
Regarding monad signatures, imagine applying the 'c in category<'v,'c> to get category<concrete, 'c> or concCategory<'c>
>>54853042
Using the new value rather than the old value is actually useful too, if you want the category to "take away" from the value, e.g. if you're creating something to tell you what the least coins for change is

Yes, you can use any editor of your choice for that and you do not have to use Google Chrome, Firefox for example supports most of the stuff from the new standard (https://developer.mozilla.org/en/docs/Web/JavaScript/New_in_JavaScript/ECMAScript_6_support_in_Mozilla) and I doubt you'll heavily utilize those, you'll probably work on some standard old ass JS so worry not.
