The full documentation behind that function is [here][1]

..which is true enough, as I haven't initialized it. I've looked through PortMidi.h and most of the internet trying to find PortMidiStream and how to initialize it with no success. The header file just has a typedef for it and a comment saying

scrapy->output.json->delete old data from db->load output.json into the database
There are always some small numbers of scraping errors, due to a couple of pages having a slightly different html format or broken links on the website, and that's ok.
What I am trying to figure out is what the best strategy to "fail" the process is, if the number of scraping errors gets too high? That would probably indicate a major change to the website or the problem with the website at that moment.

- Does splunk peform wildcard searches, proximity searches, regex searches? I know
it can do fielded searches.

Thank you. | 0 |

The provided link goes to <a href="http://www.amazon.com">amazon.com</a>, but for historical reasons I have my wish lists at <a href="http://www.amazon.co.uk">amazon.co.uk</a>. I have quite a few titles on my various lists, so I prefer to add all new books to the same site, making it easier to keep track of what I plan to buy. However, sometimes I will find a book that is not available on the UK site, so I have to maintain a separate list on the US site anyway.
I would like to have my book lists on a different site, ideally stored alongside other resources I want to keep track of. So far I have come up with the following types of information that I need to organize:
* Books I plan on buying or researching further.
* Events, courses and conferences I plan to attend or find out more about
* Articles I want to read or keep for future reference.
* Various URLs.
* Movies I want to see (i.e. IMDB links).
* Music (albums, songs) I want to check out.
* Various thoughts, notes and ideas (possibly related to a current or future project)
Today I use a combination of browser bookmarks, <a href="http://www.evernote.com">Evernote</a> notes, Amazon wish lists, blog drafts and files stored on <a href="http://www.jungledisk.com">JungleDisk</a> drives too keep track of all this information. If something is specific to a given project, I will store the information in the project's Subversion repository.
Common for all these types of information is that many of them would benefit from some integration with a third-party provider (i.e. links to book information on Amazon, links to music/band information on <a href="http://www.allmusic.com">allmusic.com</a> or Wikipedia, links to movie reviews on IMDB, etc.). I would also like to be able to organize everything in one place, ideally with tags and folders.
I know I can make everything into links and organize them on delicious or make everything into notes and put them on Evernote, but maybe there exists a better site with direct support for many of these information types already?
How do people here organize their (online) resources, notes and ideas?
Note: Some of you may wonder what this has to do with programming, but since programming is a natural part of my everyday life, I don't really see any significant difference between organizing articles on functional programming or reviews of the latest Batman movie. I would still like to have it all accessible—and searchable—in one place.
Also note that I'm not looking for yet another social bookmarking web site. I only need the information to be accessible to me, and sharing them with other people or adding friends on the site is of no importance. I guess a desktop application would do the job, but a web site would be more convenient to access from anywhere. | self-improvement | organizing | research | online-resources | null | 01/28/2012 01:09:04 | off topic | How do you organize your (online) resources and researched data?

So in short, I am not really satisfied with either
1. Iterating thru by index bounded by lengths, or even worse, off-by-ones and twos

I want to develop an application with simple Quiz-like games (think of a question , answer, a timer, high-scores/ranking, not much more)
For that I want to use Rails and some javascript library that let me have some modern effects on the GUI (being a GUI the least you can ask is for an atractive interface)
I first considered ExtJS but now I think is too serious for this.
Also there are millions of extensions for prototype(http://stickmanlabs.com/lightwindow/ http://underwhelm.net/pinwheel/ etc) that looks more casual but dont know if they will play well with rails
So what is in general the best Javascript gui/widgets library out there when the backend is going to be Rails?
And in my particular case what would you recommend?

february = pd.date_range(pd.datetime(2012,2,1),pd.datetime(2012,2,29,23,50),freq='10min')
march = pd.date_range(pd.datetime(2012,3,1),pd.datetime(2012,3,31,23,50),freq='10min')
data_jan = np.zeros(size(january))+1
data_feb = np.zeros(size(february))+2
data_march = np.zeros(size(march))+3
df1 = pd.DataFrame(data_jan,index=january)
df2 = pd.DataFrame(data_feb,index=february)
df3 = pd.DataFrame(data_march,index=march)
df = pd.concat([df1,df2,df3])
df.resample('M',how='mean')
If now, I remove the last day by :
january = pd.date_range(pd.datetime(2012,1,1),pd.datetime(2012,1,31,00,00),freq='10min')
february = pd.date_range(pd.datetime(2012,2,1),pd.datetime(2012,2,29,00,00),freq='10min')
march = pd.date_range(pd.datetime(2012,3,1),pd.datetime(2012,3,31,00,00),freq='10min')
I get (nearly) what I want:

Once a developer becomes familiar with one language, it is easier to learn another language by mapping common concepts and differences.
I have tried to list some generic questions which might help in mapping programming concepts to the way they are implemented in the language.
Are there any more questions which can be asked for a programming language?
I think if we can answer these questions for a language, it will give a good grasp of it's strengths, weaknesses, and how to work with it.
1. What constructs does the language offer for modularity (namespaces, objects, functions, modules)?
2. What are the first class citizens (types... including primitives) of this language?
3. What type of access control features does the language offer?
4. What kind of abstraction, and encapsulation does this language offer?
5. What constructs does this language offer for managing program flow?
6. How does one interact with files in this language?
7. How does one hold object (collections)?
8. How do we manage exceptional conditions?
9. Does the language have any in-built security features?
10. What concurrency model does the language support?
11. How does this language manage cleanup of resources and memory?
12. What are the important API classes in this language?
13. What are the main features of the languages runtime?
14. Does the language offer meta-programming support?
15. Are there any features unique to this language?
I came up with this list of questions which I am hoping will help me learn other languages from my base of Java development.
Is making such a list a good approach to learning another language?
Can we add more questions?
Is it possible to create a list of such questions, which will be sufficient to approach any language, or will the list always fall short for at least some languages?

We try to give unique "homework assignments" to our interviewees between their initial and their second interviews. These projects are designed to discover things about their programming personality.
I'm sure I can find [places online][1] who provide some kind of usuable LMC model.
My primary concern with a Little Man Computer problem, is whether or not people know about it. If someone doesn't know it, if it would be hard to learn. It seems that 2/5 of my co-workers have not heard of LMC.
Would a simple program on LMC be too "hard" of a project to assign for a 4-5 day task? We try to assign something that should only take 3-4 hours to write (Fibonacci Sequence, Binary Tree Sorting, etc). Would the learning curve on this be too high?
Could those of you who have not heard of LMC, look it over and tell me if you think it would be hard to figure out (I have a biased opinion. I love LMC).
Thanks in advance!

As part of this I am tweaking the type attribute of textfields, to give the user the best input tools for the expected data type.
One issue I have come up against in touchscreen mobile devices is that browsers on different OSes, and even different browsers on the same OS, show different onscreen keyboards when input type="number" is used.
Safari on iOS 4.3.3 (iPhone 4) and Chrome on Android 2.3.4 include a decimal point, but Firefox on Android 2.3.4 does not.
I have tried adding the step attribute (step="0.1") with no improvement in Firefox.
If I cannot show the decimal point I will need to show Firefox the full QWERTY keyboard, which is obviously not going to make for the best user experience. It also raises the issue of browser/device sniffing. Either I'll need to make QWERTY the default, and show the numberpad to the handful of devices I can actually test on, or make numberpad the default, and switch back to QWERTY on devices which I know this will break on, the latter option being far less robust as I cannot test on every device ever made.
Testing for support for input type="number" is not a fix, as obviously the browser does support the element, it just doesn't offer enough keyboard options to enter all number types.
So.. I was wondering if anyone knew of a way to test for the presence of a certain key (such as the decimal point) in the keyboard the browser/OS assigns to the input type, and/or if anyone else has some better suggestions, as I'm quite new to mobile devices.
I should also mention that I am using JavaScript here, as this is a website, not a native App.

1. Aborts if 32bit
2. Checks for a JRE - installs if not
3. Option to install Tomcat (embedded installer)
4. Option to deploy WARs (potentially this could be in the above Tomcat or another instance on the same box)
(*[Here][1] is the entire script if need be.*)
I am thinking of using `ReadRegStr` to try and present the user with a list of available Tomcat instances.
However, what I was hoping to do...
**Conundrum**:
At the end of the NSIS script, I wanted to dump some shortcuts on the Desktop with links to the application that gets deployed under Tomcat.
However, from registry entries alone, I cannot get at the port number.
What is the best approach here? I imagine I need to dive into a config file under the Tomcat folder or is their a simpler way?

Here is a collection of common questions and their answers. Feel free to edit and add your own.
*I obviously learnt all this information from somewhere too. Various forum posts, StackOverflow answers and my own experimenting brought me to all these solutions. Credit goes to those who posted some sample code that I've since used and modified. I don't remember who you all are - but hats off to you!*
## How Do I Select An Image From the User's Images or From the Camera? ##
You use `UIImagePickerController`. The documentation for the class gives a decent overview of how one would use it, and can be found [here][1].
Basically, you create an instance of the class, which is a modal view controller, display it, and set yourself (or some class) to be the delegate. Then you'll get notified when a user selects some form of media (movie or image in 3.0 on the 3GS), and you can do whatever you want.
## My Delegate Was Called - How Do I Get The Media? ##
The delegate function signature is the following:
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info;
You should put a breakpoint in the debugger to see what's in the dictionary, but you use that to extract the media. For example:
UIImage* image = [info valueForKey:@"UIImagePickerControllerOriginalImage"];
There are other keys that work as well. You can figure them out by looking in the debugger.
## OK, I Got The Image, But It Doesn't Have Any Geolocation Data. What gives? ##
Unfortunately, Apple decided that we're not worthy of this information. When they load the data into the `UIImage`, they strip it of all the EXIF/Geolocation data.
## Can I Get To The Original File Representing This Image on the Disk? ##
Nope. For security purposes, you only get the `UIImage`.
## How Do I Modify The Pixels of the `UIImage`? ##
The `UIImage` is immutable, meaning you can't change it. However, you can get a copy of the pixels in order to modify them. One method is the following:
UIImage* image = ...; // An image
NSData* pixelData = (NSData*) CGDataProviderCopyData(CGImageGetDataProvider(image.CGImage));
void* pixelBytes = [pixelData bytes];
// Take away the red pixel, assuming 32-bit RGBA
for(int i = 0; i < [pixelData length]; i += 4) {
bytes[i] = 0; // red
bytes[i+1] = bytes[i+1]; // green
bytes[i+2] = bytes[i+2]; // blue
bytes[i+3] = bytes[i+3]; // alpha
}
And if you wanted to create a new image using these pixels, you can do:
NSData* newPixelData = [NSData dataWithBytes:pixelBytes length:[pixelData length]];
UIImage* newImage = [UIImage imageWithData:newPixelData]; // Huzzah
There are other ways, and Apple wrote a very nice article that goes over the various methods. You can find it [here][2].
## After I Select 3 Images From The Camera, I Run Out Of Memory. Help! ##
You have to remember that even though on disk these images take up only a few hundred kilobytes at most, that's because they're compressed as a PNG or JPG. When they are loaded into the `UIImage`, they become uncompressed. A quick over-the-envelope calculation would be:
width x height x 4 = bytes in memory
That's assuming 32-bit pixels. If you have 16-bit pixels (some JPGs are stored as RGBA-5551), then you'd replace the `4` with a `2`.
Now, images taken with the camera are `1600 x 1200` pixels, so let's do the math:
1600 x 1200 x 4 = 7,680,000 bytes = ~8 MB
8 MB is a lot, especially when you have a limit of around 24 MB for your application. That's why you run out of memory.
## OK, I Understand Why I Have No Memory. What Do I Do? ##
There is never any reason to **display** images at their full resolution. The iPhone has a screen of `480 x 320` pixels, so you're just wasting space. If you find yourself in this situation, ask yourself the following question: Do I need the full resolution image?
If the answer is yes, then you should save it to disk for later use.
If the answer is no, then read the next part.
Once you've decided what to do with the full-resolution image, then you need to create a smaller image to use for displaying. Many times you might even want several sizes for your image: a thumbnail, a full-size one for displaying, and the original full-resolution image.
## OK, I'm Hooked. How Do I Resize the Image? ##
Unfortunately, there is no defined way how to resize an image. Also, it's important to note that when you resize it, you'll get a new image - you're not modifying the old one.
There are a couple of methods to do the resizing. I'll present them both here, and explain the pros and cons of each.
**Method 1: Using UIKit Functions**
+ (UIImage*)imageWithImage:(UIImage*)image scaledToSize:(CGSize)newSize;
{
// Create a graphics image context
UIGraphicsBeginImageContext(newSize);
// Tell the old image to draw in this new context, with the desired
// new size
[image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
// Get the new image from the context
UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
// End the context
UIGraphicsEndImageContext();
// Return the new image.
return newImage;
}
This method is very simple, and works great. It will also deal with the UIImageOrientation for you, meaning that you don't have to care whether the camera was sideways when the picture was taken. **However**, this method is not thread safe, and since thumbnailing is a relatively expensive operation (approximately ~2.5s on a 3G for a `1600 x 1200` pixel image), this is very much an operation you may want to do in the background, on a separate thread.
**Method 1: Using CoreGraphics Functions**
+ (UIImage*)imageWithImage:(UIImage*)sourceImage scaledToSize:(CGSize)newSize;
{
CGFloat targetWidth = targetSize.width;
CGFloat targetHeight = targetSize.height;
CGImageRef imageRef = [sourceImage CGImage];
CGBitmapInfo bitmapInfo = CGImageGetBitmapInfo(imageRef);
CGColorSpaceRef colorSpaceInfo = CGImageGetColorSpace(imageRef);
if (bitmapInfo == kCGImageAlphaNone) {
bitmapInfo = kCGImageAlphaNoneSkipLast;
}
CGContextRef bitmap;
if (sourceImage.imageOrientation == UIImageOrientationUp || sourceImage.imageOrientation == UIImageOrientationDown) {
bitmap = CGBitmapContextCreate(NULL, targetWidth, targetHeight, CGImageGetBitsPerComponent(imageRef), CGImageGetBytesPerRow(imageRef), colorSpaceInfo, bitmapInfo);
} else {
bitmap = CGBitmapContextCreate(NULL, targetHeight, targetWidth, CGImageGetBitsPerComponent(imageRef), CGImageGetBytesPerRow(imageRef), colorSpaceInfo, bitmapInfo);
}
if (sourceImage.imageOrientation == UIImageOrientationLeft) {
CGContextRotateCTM (bitmap, radians(90));
CGContextTranslateCTM (bitmap, 0, -targetHeight);
} else if (sourceImage.imageOrientation == UIImageOrientationRight) {
CGContextRotateCTM (bitmap, radians(-90));
CGContextTranslateCTM (bitmap, -targetWidth, 0);
} else if (sourceImage.imageOrientation == UIImageOrientationUp) {
// NOTHING
} else if (sourceImage.imageOrientation == UIImageOrientationDown) {
CGContextTranslateCTM (bitmap, targetWidth, targetHeight);
CGContextRotateCTM (bitmap, radians(-180.));
}
CGContextDrawImage(bitmap, CGRectMake(0, 0, targetWidth, targetHeight), imageRef);
CGImageRef ref = CGBitmapContextCreateImage(bitmap);
UIImage* newImage = [UIImage imageWithCGImage:ref];
CGContextRelease(bitmap);
CGImageRelease(ref);
return newImage;
}
The benefit of this method is that it is thread-safe, plus it takes care of all the small things (using correct color space and bitmap info, dealing with image orientation) that the UIKit version does.
## How Do I Resize and Maintain Aspect Ratio (like the AspectFill option)? ##
It is very similar to the method above, and it looks like this:
+ (UIImage*)imageWithImage:(UIImage*)sourceImage scaledToSizeWithSameAspectRatio:(CGSize)newSize;
{
CGSize imageSize = sourceImage.size;
CGFloat width = imageSize.width;
CGFloat height = imageSize.height;
CGFloat targetWidth = targetSize.width;
CGFloat targetHeight = targetSize.height;
CGFloat scaleFactor = 0.0;
CGFloat scaledWidth = targetWidth;
CGFloat scaledHeight = targetHeight;
CGPoint thumbnailPoint = CGPointMake(0.0,0.0);
if (CGSizeEqualToSize(imageSize, targetSize) == NO) {
CGFloat widthFactor = targetWidth / width;
CGFloat heightFactor = targetHeight / height;
if (widthFactor > heightFactor) {
scaleFactor = widthFactor; // scale to fit height
}
else {
scaleFactor = heightFactor; // scale to fit width
}
scaledWidth = width * scaleFactor;
scaledHeight = height * scaleFactor;
// center the image
if (widthFactor > heightFactor) {
thumbnailPoint.y = (targetHeight - scaledHeight) * 0.5;
}
else if (widthFactor < heightFactor) {
thumbnailPoint.x = (targetWidth - scaledWidth) * 0.5;
}
}
CGImageRef imageRef = [sourceImage CGImage];
CGBitmapInfo bitmapInfo = CGImageGetBitmapInfo(imageRef);
CGColorSpaceRef colorSpaceInfo = CGImageGetColorSpace(imageRef);
if (bitmapInfo == kCGImageAlphaNone) {
bitmapInfo = kCGImageAlphaNoneSkipLast;
}
CGContextRef bitmap;
if (sourceImage.imageOrientation == UIImageOrientationUp || sourceImage.imageOrientation == UIImageOrientationDown) {
bitmap = CGBitmapContextCreate(NULL, targetWidth, targetHeight, CGImageGetBitsPerComponent(imageRef), CGImageGetBytesPerRow(imageRef), colorSpaceInfo, bitmapInfo);
} else {
bitmap = CGBitmapContextCreate(NULL, targetHeight, targetWidth, CGImageGetBitsPerComponent(imageRef), CGImageGetBytesPerRow(imageRef), colorSpaceInfo, bitmapInfo);
}
// In the right or left cases, we need to switch scaledWidth and scaledHeight,
// and also the thumbnail point
if (sourceImage.imageOrientation == UIImageOrientationLeft) {
thumbnailPoint = CGPointMake(thumbnailPoint.y, thumbnailPoint.x);
CGFloat oldScaledWidth = scaledWidth;
scaledWidth = scaledHeight;
scaledHeight = oldScaledWidth;
CGContextRotateCTM (bitmap, radians(90));
CGContextTranslateCTM (bitmap, 0, -targetHeight);
} else if (sourceImage.imageOrientation == UIImageOrientationRight) {
thumbnailPoint = CGPointMake(thumbnailPoint.y, thumbnailPoint.x);
CGFloat oldScaledWidth = scaledWidth;
scaledWidth = scaledHeight;
scaledHeight = oldScaledWidth;
CGContextRotateCTM (bitmap, radians(-90));
CGContextTranslateCTM (bitmap, -targetWidth, 0);
} else if (sourceImage.imageOrientation == UIImageOrientationUp) {
// NOTHING
} else if (sourceImage.imageOrientation == UIImageOrientationDown) {
CGContextTranslateCTM (bitmap, targetWidth, targetHeight);
CGContextRotateCTM (bitmap, radians(-180.));
}
CGContextDrawImage(bitmap, CGRectMake(thumbnailPoint.x, thumbnailPoint.y, scaledWidth, scaledHeight), imageRef);
CGImageRef ref = CGBitmapContextCreateImage(bitmap);
UIImage* newImage = [UIImage imageWithCGImage:ref];
CGContextRelease(bitmap);
CGImageRelease(ref);
return newImage;
}
The method we employ here is to create a bitmap with the desired size, but draw an image that is actually larger, thus maintaining the aspect ratio.
## So We've Got Our Scaled Images - How Do I Save Them To Disk? ##
This is pretty simple. Remember that we want to save a compressed version to disk, and not the uncompressed pixels. Apple provides two functions that help us with this (documentation is [here][3]):
NSData* UIImagePNGRepresentation(UIImage *image);
NSData* UIImageJPEGRepresentation (UIImage *image, CGFloat compressionQuality);
And if you want to use them, you'd do something like:
UIImage* myThumbnail = ...; // Get some image
NSData* imageData = UIImagePNGRepresentation(myThumbnail);
Now we're ready to save it to disk, which is the final step (say into the documents directory):
// Give a name to the file
NSString* imageName = "MyImage.png";
// Now, we have to find the documents directory so we can save it
// Note that you might want to save it elsewhere, like the cache directory,
// or something similar.
NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString* documentsDirectory = [paths objectAtIndex:0];
// Now we get the full path to the file
NSString* fullPathToFile = [documentsDirectory stringByAppendingPathComponent:imageName];
// and then we write it out
[imageData writeToFile:fullPathToFile atomically:NO];
You would repeat this for every version of the image you have.
## How Do I Load These Images Back Into Memory? ##
Just look at the various `UIImage` static initialization functions, such as `imageWithContentsOfFile:` in the Apple [documentation][3].

NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString* documentsDirectory = [paths objectAtIndex:0];
// Now we get the full path to the file
NSString* fullPathToFile = [documentsDirectory stringByAppendingPathComponent:imageName];

You would repeat this for every version of the image you have.

Just look at the various `UIImage` static initialization functions, such as `imageWithContentsOfFile:` in the Apple [documentation][3].

* A Partner has a OneToMany to Profiles (and vice versa)
* A Partner has a ManyToMany to Services
What I'm trying to achieve is that when I load a profile, I want its owning Partner to be loaded, and the Partner's Services at the same time. And yes, I want them to be eagerly loaded since they are rarely of great sets, and they are almost always needed all at the same time in this system.
An example scenario is:
* Partner A has 3 profiles
* Partner A has 5 services
* The partners first Profile is fetched (profileX), at the same time the Partner and the Partner's Services are loaded.
Here is where my problem occurs (in the getProfile call in my DAO): Sometimes only the first service (based on id) is loaded from the database, and sometimes all 5 services are loaded.

Everything else seems to be working fine other than that I am having problems to redirect the person to the current page after login.
I have a page where I have some interview questions and a typical url for it would be like
/questions/?company=google
This page contains a list of questions for the company google, but to view the answer the person needs to login. The answers are displayed in a dropdown box. However when the user clicks on login a request is sent to the `login` page as follows
/login/?next=/questions/
And the get parameter which was actually there in my actual page is not sent because of the `&` in my url. How can I solve this problem. It does not look nice that the person is redirected to a different page from where he/she tried to login.
I know sending the `next` parameter as a `GET` variable is not the solution, but is there a way I can send the `redirect link` as a `POST` variable from the template.
I tried another thing, in my view that displays the questions list. I set session variables which contains the url of the current link . If a user clicks on login, in my login view I check for this particular session variable. If it is set then I redirect to that page.
However the session variable is not received in the login view, I am not sure but I think the session is reset when the user goes to the login view.
Any suggestions are appreciated. | django | session | url | redirect | null | null | open | How to redirect to page which has GET parameters after login using the {{next}} variable in django

I have a page where I have some interview questions and a typical url for it would be like
/questions/?company=google
This page contains a list of questions for the company google, but to view the answer the person needs to login. The answers are displayed in a dropdown box. However when the user clicks on login a request is sent to the `login` page as follows
/login/?next=/questions/
And the get parameter which was actually there in my actual page is not sent because of the `&` in my url. How can I solve this problem. It does not look nice that the person is redirected to a different page from where he/she tried to login.
I know sending the `next` parameter as a `GET` variable is not the solution, but is there a way I can send the `redirect link` as a `POST` variable from the template.
I tried another thing, in my view that displays the questions list. I set session variables which contains the url of the current link . If a user clicks on login, in my login view I check for this particular session variable. If it is set then I redirect to that page.
However the session variable is not received in the login view, I am not sure but I think the session is reset when the user goes to the login view.
Any suggestions are appreciated. | 0 |

However, it's only working properly when I'm using frequencies that are both power of two, say down-sampling from 32768 to 8192. I perform an FFT on the 32k data, discard the top 3/4 of the data and then perform an inverse FFT on the remaining 1/4.
However, whenever I try to do this with data that doesn't line up properly one of two things happen: The math library I'm (Aforge.Math) using throws a fit, because my samples are not a power of two. If I try to zero-pad the samples so they become power of twos, it get gibberish out on the other end. I also tried to use a DFT instead, but it ends up being insanely slow (this needs to be done in real time).
How would I go about to zero pad the FFT data properly, both on the initial FFT and the inverse FFT at the end? Assuming I have a sample at 44.1khz that needs to get to 16khz, I currently try something like this, the sample being 1000 in size.
1. Pad input data to 1024 at the end
2. Perform FFT
3. Read the first 512 items into an array (I only need the first 332, but need ^2)
4. Perform inverse FFT
5. Read the first 332 items into the audio play buffer
From this, i get garbage out at the end. Doing the same thing but without having to pad at step 1 and 3 due to the samples already being ^2, gives a correct result. | c# | .net | math | audio | aforge | 07/24/2012 16:43:49 | off topic | How to resample audio using FFT or DFT

public class SomeFileReader() {
public virtual IEnumerable<Record> Records()
{
using (StreamReader sr = new StreamReader(this.Path, this.Encoding, true))
{
while (!sr.EndOfStream)
yield return this.RecordParser.Parse(sr.ReadLine()) as Record;
}
}
A `Record` has, amongst many other properties (and thus being quite large 'memory/storage wise'), an `Id` property (which is a `Key` object that consists of 2 "parts"). For completeness this looks something like:
public class Key : IEquatable<Key>
{
public string OperatorCode { get; set; }
public string Key { get; set; }
public bool Equals(Key other)
{
return (this.OperatorCode.Equals(other.OperatorCode, StringComparison.OrdinalIgnoreCase))
&& (this.Key.Equals(other.Key, StringComparison.OrdinalIgnoreCase));
}
}
The file contains the records in "key order", so it is (guaranteed to be) sorted by the Record's `ID` on-disk.
I also have, in memory, a `List<Key>` of records that I want to process from the `SomeFileReader`. Currently my testfile is only a few megabytes large but I am forseeing this to grow very large in the near future. At this moment I just read the entire file into memory using a `Dictionary<Key, Record>` for easy/fast retrieval of specific records I want to process from my list of "to be processed" records. This would be similar to:
var recordsfromfile = MyFileImporter.Records().ToDictionary(k => k.Key.Key);
This will be problematic once the file grows (too) large ofcourse.
But since I am exposing an `IEnumerable<Record>` I was thinking... I shouldn't have to read the file into memory *completely* since the records are in key order. A simple [Intersect()][1] with my list of to-be-processed ID's should suffice. The `Key` already implements `IEquatable` and *should* I need an `IEQualityComparer<Key>` that wouldn't be hard to implement at all. But I (think I) digress..
The `Intersect()` documentation tells me:
> When the object returned by this method is enumerated, Intersect
> enumerates *`first`*, collecting all distinct elements of that sequence.
> It then enumerates *`second`*, marking those elements that occur in both
> sequences. **Finally**, the marked elements are yielded in the order in

<sup>(Emphasis mine)</sup>
So, if I understand correcly, if *`first`* would be my `IEnumerable<Record>` the file will still be read into memory completely. And even if it would be *`second`* all matches with my 'to-be-processed' list would still be read into memory which could still be a very large amount of data. Or am I misreading the documentation and is this "Finally" tripping me up and/or am I misunderstanding the documentation?
What I want to prevent, obviously, is
- a) not reading a large wad of data into memory for the sole purpose of processing some of the records in them one-by-one after which I don't care about those records (the processing will write the result out somewhere else for example)
- b) not (re)opening the same file again and again for each record on my 'to-be-processed' list (so I want to be careful not to reset my iterator)
Long story short; will the `Intersect()` do what I want it to do? Should I use another method? Nested for-loop? Any other ideas on how to handle this efficiently?<br>
__<br>
P.s. I was just hit by a brainwave about using Linq for this purpose in bed and can't get to sleep before I figure this out. Unfortunately, I am on vacation and miles away from a decent Visual Studio instance to just simply test this out. That will have to wait until after my vaction (so the misses says... we'll see about that...) ![smiley][2]
