How to get to last NTFS MFT record?
The MFT location isn't always fixed on the volume. You should get the starting MFT offset from the boot sector (sector 0 of the volume, you can find the structure online). The first file in the MFT is the "$MFT" file which is the file record for the entire MFT itself. You can parse the attributes of this file like any other file and get it's data run list. When you know the size of each fragment in clusters, parse the last cluster for each 1024 byte record of the last fragment (although I believe a fragmented MFT is rare). The last record in the MFT is the last record in that particular cluster marked "FILE0", if you encounter a null magic number that would be 1024 bytes too far. Or you can just get the file size from it's attributes and calculate the offset to the end of the MFT based o

NTFS vs. File Share
Short answer: No. In Windows each file and directory has an ACL controlling access to it. Each file share also has an ACL controlling access to the share. When you access a remote file through a share you are doing so using the credentials used to login to the local computer. (You can connect using different credentials by entering a username/password when connecting). The remote computer tests the supplied credentials against the ACL on the share. Once you are past that, then every file you attempt to access on the remote machine through this connection will be checked using your credentials against the ACL on the file and the share. This allows a file share to offer more restricted access to some files than if the same user were attempt to access them locally. (So you could share file

NTFS Journal USN_REASON_HARD_LINK_CHANGE event
As always with the USN, I expect you'll need to go through a bit of trial and error to get it to work right. These observations/guesses may, I hope, be helpful: When the last hard link to a file is deleted, the file is deleted; so if the last hard link has been removed you should see USN_REASON_FILE_DELETE instead of USN_REASON_HARD_LINK_CHANGE. I believe that each reference number refers to a file (or directory, but NTFS doesn't support multiple hard links to directories AFAIK) rather than to a hard link. So immediately after the event is recorded, at least, the file reference number should still be valid, and point to another name for the file. If the file still exists, you can look it up by reference number and use FindFirstFileNameW and friends to find the current links. Comparin

NTFS - file record size
It's not actually that much of a waste. You should try to look at what happens when the number of attributes stored in the file record exceeds 1 KB. (by adding additional file names, streams, etc.) It is not clear (to me at least) for different versions of NTFS if the additional attributes are stored in the data section of the volume or in another File Record. In previous versions of NTFS the size of a MFT File Record was equal to the size of a cluster (generally 4KB) which was a waste of space since sometimes all the attributes would take less than 1 KB of space. Since NT 5.0 (I may be wrong), after some research, Microsoft decided that all MFT File Records should be 1KB. So, one reason for storing that number may be backwards compatibility. Imagine you found an old hard drive which stil

Viewing Ciphertext of Encrypted File on NTFS (EFS)
The way you open an encrypted file in order to read its raw encrypted contents (e.g. for a backup/restore application) is to use the: OpenEncryptedFileRaw, ReadEncryptedFileRaw, WriteEncryptedFileRaw, and CloseEncryptedFileRaw api functions. Writing the code on the fly, in a hypothetical hybrid language: void ExportEncryptedFileToStream(String filename, Stream targetStream) { Pointer context; res = OpenEncryptedFileRaw("C:UsersIanwallet.dat", 0, ref context); if (res <> ERROR_SUCCESS) RaiseWin32Error(res); try { res = ReadEncryptedFileRaw(exportCallback, null, context); if (res != ERROR_SUCCESS) RaiseWin32Error(res); } finally { CloseEncryptedFileRaw(context) } } function ExportCallback(pbData: PBYTE, pvCallbackCo

How does NTFS handle the conflict of short file names?
NTFS won't create two short names like that. The first will be THISIS~1.txt and the second will be THISIS~2.txt. For example, open a command prompt and from the root of C: drive type C:>dir prog* /x /ad<Enter> On a Windows 7 64-bit system you will see output similar to this 03/28/2013 12:24 PM <DIR> PROGRA~1 Program Files 07/31/2013 11:09 AM <DIR> PROGRA~2 Program Files (x86) 12/10/2012 05:30 PM <DIR> PROGRA~3 ProgramData

NTFS sparse file data runs ($UsnJrnl)
No, it means that $UsnJrnl occupies 2576 clusters on disk. Sparse clusters don't occupy any space on disk, if you'd try to read sparse cluster, e.g. cluster 10 in your example, NTFS just returns zeros. Generally, you can't determine start and end cluster of the file, since files can be fragmented - your example says that first 1408 clusters are not allocated on disk at all, then 128 clusters of that file occupy disk clusters 510119 - 510247, then 2448 clusters of the file occupy disk clusters 256 - 2704; so in this case you can't say that file begins by cluster X (on disk) and ends by cluster Y (on disk) - it's possible only if file is not fragmented (when it uses only one cluster run).

access to ntfs stream for a very long filename fails
As the very helpful page on CreateFile says referring to the lpFileName parameter which specifies the filename: In the ANSI version of this function, the name is limited to MAX_PATH characters. To extend this limit to 32,767 wide characters, call the Unicode version of the function and prepend "?" to the path. Since you are contemplating BackupRead obviously you are wanting to access this stream programatically. If so, test things programatically. Trying all these operations from the command prompt is a crap-shoot and will not establish anything more than the ability to perform such operations from the command prompt. With that in mind, let's try this simple program - boilerplate code removed: #include "stdafx.h" int APIENTRY _tWinMain(HINSTANCE, HINSTAN

Reformat a JSON object
You're pretty close, but there are a few issues with the creation of your new objects. var myObject = ['destinations']; This creates an array with a single element, the string "destinations". What you actually want is an object with a property destinations that is an empty array, so change it to: var myObject = { destinations: [] }; The .each() iteration is correct, but the code for each iteration isn't. What your code is doing is taking your array myObject, and setting the destinations property (which doesn't exist in the first iteration) of that equal to the object for the current iteration; you instead want to be pushing the new object into the array. There's also a problem with the creation of the object, since you can't have dynamic keys when creating an object literal. $.e

Find numbers within content and reformat them
I think this is what you are going for: $("#mytable").find("td").each(function () { var content = this.innerHTML; content = content.replace(/$(d*(?:.d*)?)/g, function (m1, m2) { return "$" + parseFloat(m2).toFixed(2); }); this.innerHTML = content; }); Fiddle This will replace any finding of a dollar sign with a number following it and then make that number fixed to two decimals and replace it. Based on your comment, to allow for £ as well as $, try this in place of the above: content = content.replace(/([£$])(d*(?:.d*)?)/g, function (m0, m1, m2) { return m1 +""+ parseFloat(m2).toFixed(2); }); Fiddle It catches for [£$] (one of either symbol) and puts that in the first capture group which it passes to the function as m1 the first group is the entire

Using R to reformat data from cross-tab to one-datum-per-line format
In R and several other programs, this process is referred to as "reshaping" data. In fact, the Tableau page that you originally linked to speaks of their "Excel Reshaper plugin". In base R, there are a few functions to reshape data, such as the (notorious) reshape() function which takes panel data from a wide form to a long form, and stack() which creates skinny stacks of your data. The "reshape2" package seems to be much more popular for such data transformations, though. Here's an example of "melting" your sample data, which I've stored in a data.frame named "mydf": library(reshape2) melt(mydf, id.vars=c("ID", "Gender", "School"), value.name="Score", variable.name="Subject") # ID Gender School Subject Score # 1 1 M West Math 90 # 2 2 F South Math 50

(Ugly doesn't matter since you'd never ever commit it w/out everything working). Please just delete the line.

In either of the above cases it should be so temporary of a fix that you shouldn't worry about it.

You also need to hook ZwReadFile and ZwWriteFile if you want to control reading from file and writing to it; and ZwMapViewOfSection / ZwUnmapViewOfSection to work with file mappings. For directory enum you need to hook ZwQueryDirectoryFile. All of these functions can easily be hooked from usermode.

Docker.IO Filesystem Consistancy
I don't know if this will answer your question completely, but... Doing docker run -i -t ubuntu /bin/bash will not restart any container. Instead, it will create and start a new container based on the ubuntu image. If you started a container and stopped it you can use docker start ${CONTAINER_ID}. If you did not stop it yet you can use restart. You can also commit (export) the container to a new image: see http://docs.docker.io/en/latest/commandline/command/commit/ for the correct syntax. docker export is a option as well, but all that will do is archive your container. By creating a new image using docker commit you can create multiple instances (containers) of it afterwards, all having your file in it.

Filesystem object symbology
But everyone must be facing this... No, not really, because you're really over-thinking this. Just use file:, or filename:. It doesn't matter whether your filename contains a relative or absolute path, or whether the path contains directories, and your code should reflect this. A path to a file is just a path to a file, and all paths should be treated identically by your code: It just opens the file, and raises an error if it can't. You can use filesystem utilities to extract directories and base names from a path, and they'll work just fine on any path, regardless of the presence of directories, regardless of wether the path is absolute or relative. It just doesn't matter.

I was once through autofs sources in C, looked pretty straightforward. You might want to see http://code.google.com/p/mogilefs/ as well.

How to initate full uncompression of ZFS filesystem
That's odd as usually, a better performance is observed with compression enabled. Anyway, should you really want to decompress your files, there is no need to use a new "partition" (not sure if you mean a new file-system or pool here). Assuming there is enough space to hold a copy of the biggest file in your file system, and that the files are not being concurrently use/updated by applications, you can just copy the files in the same directory then move them to their original name, overwriting the compressed original, eg: find . -type f -exec ksh -c 'for i do echo cp -p "$i" "$i.u$$" && echo mv "$i.u$$" "$i"; done' ksh {} + Remove both "echo" instructions to actually do the change.
