Is there a way to read directly from the hard drive to the GPU
The GPU is not directly connected to the system RAM. There's a bus inbetween, in current generation computers a PCI-Express bus. ATA storage has a controller inbetween. There is no direct connection between memories. BUT there is DMA, which allows certain periphials to directly access the system memory through DMA channels. DMA on PCI-Express also works between periphials. Theoretically a GPU could do DMA to the ATA controller. Practically this is of little use! Why? Because of filesystems. Even if there was some kind of driver support to let the GPU access a storage periphial directly, it'd still have to do all the filesystem business, which doesn't parallelize to the degree as GPUs are designed for. Alas regarding your question: In my OpenGL program I read from the header file t

Methods for tracking changes to hard drive
For realtime tracking when file or directory changes you can use inotify on Linux or FileSystemWatcher on Windows. Combine with rsync to get delta.

Adding a new hard drive to xampp
If you want to sort of "span" the drive, Windows has this handy feature (similar to linux's symlinking) called mklink which you can create a folder in the current directory that is just a symbolic link to the drive. Quick and easy way to span it. I am not sure of any downsides to do doing this, other than if the drive letter changes (if external drive). That way you should not have to add or change any of your paths in the config etc. Not sure if that is what you were looking for, but hopefully it helps. Also, did you try your 3rd config you pasted? Did it not work? From what I can see, as long as permissions are fine it should work that way.

making pink noise (1/f) using list of frequencies
If I am correct, what you are doing is generating noise based on a 1/f frequency. However if you read the following article: http://en.wikipedia.org/wiki/Pink_noise the frequencies are the same except that the power spectral density is S is proportional to 1/f. Hence you should not be generating noise of frequency 1/f. I would suggest reading this page for the necessary algorithms. However if the problem you are facing is that the volume is too low, try amplifying the synthesized noise by multiplying the result by a factor ex.: pinkNoise = pinkNoise * 100

Accessing a file on the server's hard drive
You cannot reach the file that is "above" the wwwroot folder by design. The way to do this is to a) copy the file there, b) setup a symbolic link (if on linux) or c) preferably, move / setup another web root folder. Alternatively, write a server script to dump the file contents.

How to identify system hard drive using Win32_DiskDrive
The documentation you linked has the answer: string SerialNumber; uint32 Signature; Your management object will have those properties in it. If you're getting null for those values then the problem is that you're using a version of Windows that doesn't support them. SerialNumber ... Windows Server 2003 and Windows XP: This property is not available. In which case you have to use the Signature property, but this requires XP SP3 I believe.

How to avoid patterns when making random perlin noise
Just to give a answer to other people who might have the same problem. I found one that produced a pretty good result. I didn't even need the rand() function. __forceinline float getRandomField(const vec3& Position) const { uint32_t seed = uint32_t(Position.x)*1087; seed ^= 0xE56FAA12; seed += uint32_t(Position.y)*2749; seed ^= 0x69628a2d; seed += uint32_t(Position.z)*3433; seed ^= 0xa7b2c49a; return (float(int(seed%2001) -1000)/1000.0f); } The key is to multiply each axis with a prime number. I found these on wikipedia: 1087,2749,3433. The hex values xor'ed with is just randomly hammered down by me. They are not primes, as far as I know. Check out the result:

Save Work Done In MS Word To A Database Not On A Hard Drive
The method you are using is extremely inefficient and I wouldn't recommend the process, but the reason that you code is failing is your length.... when you are saving your MemoryStream you are setting the length int len = Application.ActiveDocument.Content.StoryLength; but when you try to retrieve it, you are setting it int len = int.MaxValue; which would be far past the end of the data stream.

Single git repo setup tracking multiple locations on hard drive
No, there is no mechanism in git for this. Git assumes that all files that it manages (the "working copy") live in a single directory (and subdirectories); there is no support for managing two separate directories in in repo. So you'll have to somehow keep everything in one directory, probably as subdirectories HTMLTemplates and theme or similar. You could use two git repos, but I'd strongly advise against this. A single repo should contain a whole "project", i.e. everything needed to build one piece of software (excluding things like external libraries). If you split your project across two repositories, you cannot usefully branch and merge (because you'd have to do it in both repos simultaneously), you cannot easily check out old versions etc.. To solve your problem, I see a few poss

How do I bind a WPF Image element to a PNG on the local hard drive using a relative filepath derived from a DB?
You need to use custom value converter to convert strings to images if you want to load files from the file system. Image.Source, when a string is passed, expects a file name from resources. You can find implementation of a such converter here: Display an image in WPF without holding the file open.

Serial Communication gets back wrong answer when something is running in the background (like browsing the hard drive)
Note: serialPort.Write(string) is a non-blocking store into the output buffer. That means the following won't guarantee you've even finished writing your request before you stop listening for a response: serialPort.Write(request); Thread.Sleep(50); _shouldStop = true; You could add: while( serialPort.BytesToWrite > 0 ) Thread.Sleep(1); // force blocking but it's ill advised. One thing I'm wondering. There is only a single serial port here. Why do you want many different threads to work with it when you could manage the entire serial port interaction with a single thread? (Or at worse, 1 thread for input 1 thread for output) To me it makes a lot more sense to store up requests into a queue of some kind and then peel them off one at a time for processing in a single threa

trouble making drive insertion detection c#
I'm not seeing your actual MenuItem, but wherever it is, you're referencing both System.Windows.Controls and System.Windows.Forms, and so you'll have to clarify. Somewhere it's going to be something like: private MenuItem _mItem; And that'll have to change to: private System.Windows.Forms.MenuItem _mItem; (or System.Windows.Control; try one and see if it breaks!) The second error is probably accurate: change MainWindow from inheriting from Window to inheriting from System.Windows.Forms.Form and see if that fixes it. Alternately, remove the override. It's correct that System.Windows.Window has no method for WndProc, but Form does...

Send some working params to doc or save to docs db while making copy of a doc using drive api
Setting Document-Specific Parameters in a New Document I want to store some params into doc's database or at least to script content or someway that doc can know that value... You can accomplish this, but it requires that you use a script to create the document copy. While creating the copy, this script would also create an entry in a shared spreadsheet, with the ID of the new document and any parameters for that document. The onOpen() trigger function would then set document-specific values once, the first time the document is opened. If the parameters have not been set yet, the script would read the shared data, find its parameters (again, based on document ID), then store them in its ScriptDb (and, presumably, set text within the document using them).

google drive api - copyfile working only with permission for accessing all files in drive (but jst need to copy)
According to the documentation, Files.copy() requires at least one of the following three permissions: https://www.googleapis.com/auth/drive: "View and manage the files and documents in your Google Drive" which is the one you want to avoid https://www.googleapis.com/auth/drive.file: "View and manage Google Drive files that you have opened or created with this app." Which means you can freely create any file but only open the files your app created. You can only copy a file you created, but you cannot copy any other files even if it is public. https://www.googleapis.com/auth/drive.appdata: "View and manage its own configuration data in your Google Drive" Which only lets you control your application-specific Appdata folder which is probably not what you want.

Error while Retriving files from google drive using drive API. “Calling this from your main thread can lead to deadlock
You should do any code that could take a long time such as I/O or network activity on a different thread. In your situation your file retrieval would be best done within an ASyncTask. The reason for this warning is because when your code is being executed to retrieve the file from Drive, the code will block until the file retrieval has completed, this means that nothing else within the program will be able to respond, i.e. GUI will not update and input from the user trying to do stuff with the GUI will not be registered. After a few seconds, if the file retrieval still isn't complete, then the user will be presented with an ANR (Application Not Responding) message. This will either give the user the choice of waiting, if their patient, or most likely force closing your app.

Monitoring changes in Google Drive files for whole domain using Drive API
Domain-wide delegation simplifies the authentication portion for your app but you'll still need to auth as each user to get their files and changes. It may be possible for your app to "grab" all files and make itself (or a special user) the owner, then you just have one user account to scan but the "grab" process would still need to run at regular intervals to find new files created or uploaded by end users. I believe most apps that need to scan content at this level do it via cron jobs or AppEngine task queues which make it easy to chunk up the scans throughout the day. Generally they expect to scan each user account once every 24 hours or so.

Windows: How to symlink drive to another drive?
No, mklink isn't going to do it for you. What you need to do is to create a virtual hard drive (VHD) and copy the client's data to it. (Or modify the export script, which is the best thing to do.) I used Windows 7 to test my instructions below. Start-> run-> diskmgmt.msc (accept all defaults... I'm not doing anything special below) From the menu bar select Action -> Create VHD Choose the location and name the file (which will be the vhd) and specify the size and click OK. Right click on the Disk # (underneath will be Unknown and the size and "Not Initialized"). Select "Initialize Disk" & click OK Right click on the black bar of the unallocated disk space and select "new simple volume".

From audio PCM 16 bit to 8 bit - getting noise
You have a lot of noise for multiple reasons. You are firstly only filling every other value of the array, the values you are not filling are automatically zero, that distorts the waveform hugely. Secondly you are just picking the first 8 bits of the original data, this means you lose all of the information on a specific datapoint if the first 8 bits of the datapoint happen to be all zeros, the information may be in the higher bits. A naive suggestion would be to scale all of the datapoints (divide by 2^7 if signed) so that the highest datapoint is at most 8 bit, you will still lose information and introduce distortion because you are forced to save the data in integers and integer division will force values in the same (close) range to be equal after division but this should be a lot

How to add appropriate noise to a graph
The issue is that you want the noise to have a certain characteristic. You have many samples along the curve, and you'd like it to stay "connected". You'd like fairly smooth results, and you want the curve to stay closed. So, in order: random walk noise will keep the points connected. Low-pass-filtered noise will keep the curve smooth. And fix the noise endpoint to be zero (smoothly) to ensure a closed result. Here's some code that generates 16 different kinds of noise (4x4), varying the overall scale and the overall amount of filtering. You'll have to adjust both of these choices based on the "sample rate" of your data, and the overall scale of the shape. % Generate sample data [x,y] = pol2cart(0:0.01:2*pi, 1); % Pick a set of 4 noise scale, and noise filter values scales = [.01

Remove noise in an image
A series of dilation and erosion operations (called "closing") might suffice depending on your needs. You can combine the imdilate and imerode operations, performing them in sequence as imclose, or "manually" as in this example: se=strel('ball',4,4); im_er = imdilate(im,se); im_er = imerode(im_er,se); The imdilate operation increases regions of high valued pixels, the second shrinks them. There are various shapes of object with which to perform the erosion/dilation, you might need to experiment or read up on which is most useful for your scenario. In your particular case it looks like the RGB colorspace was ok for performing the morphological operations.
