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 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.

advantages and disadvantages between int vs int_fast8_t
int_fast8_t is the fastest integer type that's at least 8 bits wide. There is no reason to think that it'll be faster than int (which is typically the fastest integer type there is.) Besides, the two types could have different width, meaning they often can't be used interchangeably.

Advantages/disadvantages of configSection vs plain xml?
well, that's a good question i think. i think the only advantage is that it is known to .NET developers, so they dont need to learn the new tricks one implements in his own solution maybe a bit of security too, because the server protects web.config files but dont care to send an XML file.

Mogenerator and Xcode 4 advantages/disadvantages
This article has a detailed explanation of how to use mogenerator with XCode4, and why you would want to. In developing your app you're likely to add your own custom methods to the generated entity classes (NSManagedObject subclasses). But when you run xctool to generate the classes, all your changes are overwritten and lost! Mogenerator generates a pair of classes for each entity - one stable 'machine' class which can be re-generated from the model as you make changes, and one 'human' subclass of the machine class which you can edit and add methods to. I recommend adding a target & build phase to your Xcode project which will generate your entity classes at build time, so you never have to remember to run mogenerator manually. In addition, mogenerator adds const structs containing

Advantages/disadvantages of using ServiceStack services vs ASP.NET MVC controllers?
All the serialization/deserialization of request/response DTO's to/from Json or Xml performed by ServiceStack is bound to come at the cost of performance compared to pure C# objects that MVC controllers deal with. This doesn't sound right you should never need to do any un-necessary marshalling/de-serialization when using ServiceStack, i.e. you can call ServiceStack services directly from MVC Controllers which is just a C# method call. Serialization can be somewhat flaky when dealing with complex object graphs. E.g. in cases involving circular references... That's because you should only be sending clean, self-describing DTO's on the wire, not dumping db models with cyclical dependencies.

What are the advantages and disadvantages of these methods of creating tables with JavaScript?
If you can avoid using the elements, and just put a string into an innerHTML you'll get the best performance. Here are some different ways to create a table. Functional Code demo We can create some functions to generate our HTML. This code will be very fast (but could be faster). We'll assume this data for all of these examples. var heading = ['Name', 'Points']; var data = [ ["Joe", 50], ["Jack", 80], ["Doug <b>'the hammer'</b> Jones", 76] ]; We can then generate our table like so, document.body.innerHTML = table(heading, data); function wrapTag(tag, html) { return "<" + tag + ">" + html + "</" + tag + ">"; } function table(head, body) { return wrapTag("table", thead(head) + tbody(body)); } function thead(head) { var _th = head.map

VBA, File System Object, speed/advantages/disadvantages
Instead of using FSO, I would use DIR() if I want faster speed. However, it is not so fail-safe so you would need to conduct couple of tests and make sure it works in all occasions. For example, you may need to check individual parent folder in order to make sure they exist. Anyways, Dir() should be faster because it is a native function. Another way of solving this would be to use Batch (if you're on Widows of course!) or use command line to simply copy from one file to another file. You should see a dramatic increase in speed and you don't need to worry about checking every single subfolder for existence! I happen to have a VBA code that would use windows commandline to do what I want. I got it from the internet but tweaked some error acknowledgements to bypass what I wanted to do: O

What are the advantages / disadvantages / best practices of using FileInfo.Encrypt and Memberships for Security
Firstly you are not encrypting the passwords, sha is a hashing algorithm. Given that you are not sure about this I would strongly recommend against rolling your own authentication/authoriztion mechanism. The build in .net membership stuff is excellent, and well proven. Stick with it and you can't go wrong. Why are you encrypting the content on the server? This appears to be massively over the top, but if it's a requirement I would suggest storing the xml in an encrypted database - it will allow you to access the data far more efficiently, and will still meet your requirements.

What are the advantages and disadvantages of two methods of implement a worker/manager separated cluster
The advantages of this model is clearly given in the blog of Afkham Azeez, Director of Architecture at WSO2 on http://blog.afkham.org/2012/08/separation-of-worker-management-nodes.html Both the models have above mentioned advantages, And in the dual mode the users would still have the separation of worker-manager in the cluster but has the capability of using manager node to serve requests as well which can be important when a user needs to setup a worker-manager cluster with limited resources and wants all the cluster nodes to server requests. worker-manager clustering architecture is compatible with many WSO2 products like WSO2 Application Server, ESB, Governance Registry , Identity Server and etc. Therefor any application that you host on these servers would be subjected to High avai

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.

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

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.

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

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.

First of all, it streams the map output, if it is possible to keep it in memory this will be more efficient. I originally deployed my algorithm using MPI but when I scaled up some nodes started swapping, that's why I made the transition. The Namenode keeps track of the metadata of all files in your distributed file system. I am reading a hadoop book (Hadoop in action) and it mentioned that Yahoo estimated the metadata to be approximately 600 bytes per file. This implies if you have too many files your Namenode could experience problems. If you do not want to use the streaming API you have to write your program in the java language. I for example did a translation from C++. This has some side effects, for example Java has a large string overhead compared to C. Since my software is all abou
