storage

问题 I am using a code which is listing all the images from my device...and I'm trying to figure it out how to get images only from a specific folder, not all the images. Here is the code I'm using : ArrayList<Bitmap> images = new ArrayList<Bitmap>(); String[] projection = {MediaStore.Images.Thumbnails.DATA}; Uri uri = Uri.parse("content://media/external/images/media"); cursor = managedQuery( uri, projection, null, null, null); //cursor = managedQuery( MediaStore.Images.Media.EXTERNAL_CONTENT_URI,

问题 I am currently working on an iOS application that I allow the user to add images from their photo library into the application. I store these images on the devices file system, and access them when I need them (when they are in a UIScrollView, I could access them quite often) I just wanted to get some opinions on this approach. Should I stay with the file system method, or would it be beneficial to store these I images in CoreData instead. Any suggestions on this would be greatly appreciated.

问题 There is this flash memory IC on my board, which is connected to my STM32F04 ARM processor. USB port of the processor is available for the user. I want my flash memory to be detected as storage device when connected to PC via USB. As the first step I defined my USB class as MSC in my program which works fine. Since when I connect my board to PC, it detects a mass storage device connected, giving an error that "You should format the disc before using it". Now the question is that, how I can

问题 [1] states: "When data is deleted from a heap, the data on the page is not compressed (reclaimed). And should all of the rows of a heap page are deleted, often the entire page cannot be reclaimed" "The ALTER INDEX rebuild and reorganize options cannot be used to defragment and reclaim space in a heap (but they can used to defragment non-clustered indexes on a heap). If you want to defragment a heap in SQL Server 2005, you have three options: 1) create a clustered index on the heap, then drop

问题 I'm developing a web application in which users are allowed to upload pictures, the system will then generate thumbs for them. My problem relies on the fact that EJBs can be distributed on several servers and thus are not allowed to handle files directly. I could store the images in the databases but I was hoping to store them as files in one of the servers. How can I do this? Is there any way to centralize the storage of files? Or any approach to deal with files in Java EE with EJBs?

问题 I'm creating an app that connects online to a server to collect information. To save money from renting server space from a big corp, I was wondering if any of these free services (Dropbox, Google Drive, Microsoft Skydrive, Amazon Cloud, etc.) could be potentially used as server space? I pretty much want a "space" or "cloud" where people can connect to to collect data. Example: I have a weather app, and there is files on my server and I update the files according to the weather. I would like

问题 This is my code, private String memSize(String path){ StatFs stat = new StatFs(path); long blockSize = stat.getBlockSize(); long availableBlocks = stat.getAvailableBlocks(); long freeBlocks = stat.getFreeBlocks(); long countBlocks = stat.getBlockCount(); String fileSize = Formatter.formatFileSize(this, availableBlocks * blockSize); String maxSize = Formatter.formatFileSize(this, countBlocks * blockSize); String info = path.toString() + "\nblockSize : " + Long.toString(blockSize) + "

问题 What is the difference between persistent volume (PV) and persistent volume claim (PVC) in Kubernetes/ Openshift by referring to documentation? What is the difference between both in simple terms? 回答1: PVC is a declaration of need for storage that can at some point become available - as in bound to some actual PV . It is a bit like the asynchronous programming concept of a promise . PVC promises that it will at some point "translate" into storage volume that your application will be able to

问题 In my app i have to store Core Data Database and audio files, so i decoded to put them in Documents directory. To prevent them from backing up, when i first launch the app, i put the Don't BackUp flag like this - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [self addSkipBackupAttributeToItemAtURL:[self applicationDocumentsDirectory]]; } - (NSURL *)applicationDocumentsDirectory { return [[[NSFileManager defaultManager]
