How to remove file permissions on linux from an external hard drive? |
To make the partition accessible under Linux run:
sudo chmod -R 777 /media/<drive-name>/
this should make the mac drive accessible for you.
Changing ownership would do about the same, but you need not worry about
it.

Unmount my external hard drive in bash |
Searching for "Unmount Hard Drive Terminal" yields
http://ubuntuforums.org/showthread.php?t=842698
as the first result. >.>
russlar provides a solution:
open terminal, and run df -h. this will tell you all the hard drives
mounted. then, run sudo umount /dev/something, where somethign is the name
of the hard drive that you want to unmount.
Nothing wrong with asking, but when a solution is on the first Google
result, it's a little... odd.

how to shrink KVM hard drive image |
Images can be sparsed, and your cp might not respect that for various
reasons. I would:
check the real file usage (du -sh vm.img or qemu-img info vm.img)
use qemu-img convert -S to recreate a sparse image
convert to qcow2 to have growing and versatile image instead

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:

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.

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

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.

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.

Is it safe to compare an (uint32_t) with an hard-coded value? |
Is the following kind of code safe?
Yes, it is.
So do you know the type and size (by that I mean on how much bytes is it
stored) of hard-coded "0x03000000" ?
0x03000000 is int on a system with 32-bit int and long on a system with
16-bit int.
(As uint32_t is present here I assume two's complement and CHAR_BIT of 8.
Also I don't know any system with 16-bit int and 64-bit long.)
Is it possible that some systems consider 0x03000000 as an int and hence
code it only on 2 bytes, which would be catastrophic?
See above on a 16-bit int system, 0x03000000 is a long and is 32-bit. An
hexadecimal constant in C is the first type in which it can be represented:
int, unsigned int, long, unsigned long, long long, unsigned long long

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..

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

a such converter here: Display an image in WPF without holding the file
open.

Linux Shell Script: How to detect NFS Mount-point (or the Server) is dead? |
"stat" command is a somewhat cleaner way:
statresult=`stat /my/mountpoint 2>&1 | grep -i "stale"`
if [ "${statresult}" != "" ]; then
#result not empty: mountpoint is stale; remove it
umount -f /my/mountpoint
fi
Additionally, you can use rpcinfo to detect whether the remote nfs share is
available:
rpcinfo -t remote.system.net nfs > /dev/null 2>&1
if [ $? -eq 0 ]; then
echo Remote NFS share available.
fi
Added 2013-07-15T14:31:18-05:00:
I looked into this further as I am also working on a script that needs to
recognize stale mountpoints. Inspired by one of the replies to "Is there a
good way to detect a stale NFS mount", I think the following may be the
most reliable way to check for staleness of a specific mountpoint in bash:

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

Will SQL Server treat a USB 3.0 External Drive as local? |

the directory, it should work just fine.

Is it safe to use async with external js files? |
You can use async safely with unrelated scripts. But if you need to load

condition.
I found this article on various ways to load scripts quite useful, FWIW.

Is standard C mktime thread safe on linux? |
It's true that mktime has a side effect, but the side effect should be
harmless in most programs.
According to POSIX, the side effect will be as if tzset has been called,
which in turn merely copies the timezone information from the TZ
environment variable to the tzname array of C strings. If your application
doesn't change TZ, you will have no problem with calling mktime()
concurrently.
In addition to this, GNU libc's tzset does use a mutex to protect the
integrity of tzname. This is a quality-of-implementation addition not
guaranteed by the standard.

Adding scripts to the external pages in jquery mobile other than the home file |
How jQuery Mobile handles page changes
To understand this situation you need to understand how jQuery Mobile
works. It uses ajax to load other pages.
First page is loaded normally. Its HEAD and BODY is loaded into the DOM,
and they are there to await other content. When second page is loaded, only
its BODY content is loaded into the DOM.
Here's an official documentation:
http://jquerymobile.com/demos/1.2.0/docs/pages/page-links.html
Unfortunately you are not going to find this described in their
documentation. Ether they think this is a common knowledge or they forgot
to describe this like my other topics. (jQuery Mobile documentation is big
but lacking many things).
Solutions:
In your second page, and every other page, move your SCRIPT tag into the
BODY content, like this:

How can we use Linux from a small storage pen drive? Does it work on micro-controllers also? |
I generally hear that LINUX OS can be downloaded on flash, pen drive
(floppy disk?) etc. How > we can do that?
If you can't get it to work on your own, you can buy a ready made Linux on
a USB drive from
a site like http://www.osdisc.com or http://www.cheapbytes.com
Not all PCs, especially older PCs, can boot from the USB Drive. Even some
newer PCs are beginning to ship with security features that can interfere
with booting code. When it does work, you have to find out the proper way
to boot the USB drive. You might have only a few seconds during reboot to
enter the right key, or it will boot Windows (if Windows is installed).
The key to get to the BIOS Boot Menu might be delete or escape or F10 or
some other key (varies with PC motherboard manufacturer). A message on the

Is there an async-signal-safe way of reading a directory listing on Linux? |
If you know in advance which directory you need to read, you could call
opendir() outside the signal handler (opendir() calls malloc(), so you
can't run it from within the handler) and keep the DIR* in a static
variable somewhere. When your signal handler runs, you should be able to
get away with calling readdir_r() on that handle as long as you can
guarantee that only that one signal handler would use the DIR* handle at
any moment. There is a lock field in the DIR that is taken by readdir() and
readdir_r(), so if, say, you used the DIR* from two signal handlers, or you
registered the same handler to handle multiple signals, you may end up with
a deadlock due to the lock never being released by the interrupted handler.
A similar approach appears to also work to read a directory from a chi

Are Python [de]compression modules thread-safe on Linux? On Google App Engine? |
Your question is basically meaningless, because you're misunderstanding
some fundamental things and creating problems that don't exist. I tried
answering in comments, but there's a limit to what you can do that way,
so…
I want to do everything without using file-like objects, because App
Engine cannot provide conventional Python filenames for dynamic files.
You don't need filenames, or files, for file-like objects. That's the whole
idea behind file-like objects.
App Engine does not provide a way to open a file-like object (unless the
file was uploaded as part of the app).
No, you are still confusing file objects and file-like objects. A file
object represents an actual file on disk. GAE restricts those. A file-like
object is any object with the same API—that is, an obje

Java absolute path adds user.home property when adding quotes - Linux |
From your description it seems that you are calling the
File(java.lang.String pathname) constructor.
If so, the String used to represent your path should not use quotes.
Quotes are not considered as special characters in the abstract pathname
definition, as described in the java.io.File documentation.
An abstract pathname has two components:
An optional system-dependent prefix string, such as a disk-drive
specifier, "/" for the UNIX >root directory, or "\" for a Microsoft Windows
UNC pathname, and
A sequence of zero or more string names.
Since quotes are not special characters, they are considered part of a
name.
Example:
public static void main(String[] args) {
File quotes = new File(""C:\myFolder"");
File noQuotes = new File("C:\myFolder");

you will now have a console as that user. Now try using the command.
This is your reason. It is most probably based on your distribution -
different distros have different "settings" for different programs.
