This is very interesting topic , they use following formula to compute access interval time: BreakEvenIntervalinSeconds = (PagesPerMBofRAM / AccessesPerSecondPerDisk) × (PricePerDiskDrive / PricePerMBofRAM). It is derived using formulas for the cost of RAM to hold a page in the buffer pool and the cost of a (fractional) disk to perform I/O every time a page is needed , equating these two costs, and solving the equation for the interval between accesses. so the cost of disc I/O per access is PricePerDiskDrive / AccessesPerSecondPerDisk , My question is why disc I/O cost per access is computed

I am downloading data into my app from the internet. If I specify internal memory (=Environment.getExternalStorageDirectory()), I may have face problem of "not enough space". Sdcard mount address always differs phone to phone, so I would like to allow user to select his preferable location, where to store downloaded data. Is there any method, how to get all available storage options, whhich can be used? (generally, I would like to choose between internal memory or inserted sdcard). Thanks Please check the below code. Calculate Available Internal Storage memory StatFs stat = new StatFs

I am trying to to block certain webrequests in my google chrome extension based on data stored in chrome.storage.local. However I can't find a way to return "{cancel: true };" inside the callback function of onBeforeRequest.addListener. Or to access data from storage.local outside of it's respective callback function due to the asynchronous way of chrome.Storage.local.get(). Here is my relevant code. chrome.webRequest.onBeforeRequest.addListener( function(info) { chrome.storage.local.get({requests: []}, function (result) { // depending on the value of result.requests.[0].item I want to return

I have an Xperia Neo V that does not have any internal storage - only an SD card as external storage, while the Galaxy S3 has both internal and external storage. When using this function Environment.getExternalStorageDirectory(); I can access files only on internal storage(S3) but there is no problem with Xperia Neo V. How can I access files on both internal and external storage? I have an Xperia Neo V that does not have any internal storage All Android devices have internal storage, including the Xperia Neo V. Internal storage is where the OS and application data is stored -- without it, your

I'm using Django 1.3, and I'd like to modify the session middleware to add some methods that will help me out. In ./settings.py SESSION_ENGINE='tcore.my_sessions.MySessionStore' In ./tcore/my_sessions.py: from django.contrib.sessions.backends.db import SessionStore from django.contrib.sessions.middleware import SessionMiddleware from django.conf import settings class MySessionStore(SessionStore): .... def my custom methods here However, I keep getting some weird exceptions when I do this. What's the proper way to make a custom Session Engine? AttributeError at /create/ type object

I need to develop a system for storing large numbers (10's to 100's of thousands) of objects. Each object is email-like - there is a main text body, and several ancillary text fields of limited size. A body will be from a few bytes, to several KB in size. Each item will have a single unique ID (probably a GUID) that identifies it. The store will only be written to when an object is added to it. It will be read often. Deletions will be rare. The data is almost all human readable text so it will be readily compressible. A system that lets me issue the I/Os and mange the memory and caching would

I would like to know how to use "Storage Access Framework" to create new folder on SD card. If you give me the code it would be very good. I have already searched other questions and answers but not found how to. Add some codes that already work per "CommonsWare" answer. Note that is the only way I found that it can make new folder in sd card on my phone SS A5 with Android OS 5.1.1 public void newFolder(View view) { Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE); startActivityForResult(intent, NEW_FOLDER_REQUEST_CODE); } private static final int NEW_FOLDER_REQUEST_CODE = 43;
