storage

Could someone explain what difference between Object Storage and File Storage is please? I read about Object Storage on wiki , also I read http://www.dell.com/downloads/global/products/pvaul/en/object-storage-overview.pdf , also I read amazons docs(S3), openstack swift and etc. But could someone give me an example to understand better? All the difference is only that for 'object storage' objects we add more metadata? For example how to store image like object using some programming language (for example python)? Thanks. IMO, Object storage has nothing to do with scale because someone could

I am running a simulation from which I need to record some small numpy arrays every cycle. My current solution is to load, write then save as follows: existing_data = np.load("existing_record.npy") updated = np.dstack((existing_data,new_array[...,None])) np.save("existing_record.npy",updated) This has created a big performance bottleneck and the simulation runs at half the speed with this method. I have considered appending the numpy arrays to a list and writing it at the end of the simulation but this could obviously lead to running out of ram or losing data in a crash etc. Are there any

I want to make 20 Virtual Computers and I want to download same files on them, however it will take too long time to get on each one of them and download the same files. Is there anyway I can have the files already downloaded on the other Virtual machines that I will create so I don't have to re-download on each single one? I'm not sure that I understand what you're trying to do. If you want to create a base image of software that all your VMs will share, you should be able to set up a single virtual machine, then sysprep the image, capture it, and use that to spin up new virtual machines with

I am new to android and trying to develop my first app. In my app, I have a listview activity that lists a group of stores. When the app users (anyone who downloaded the app) select their favorite store, +1 should be added to that store count. At a specific time during the year, I want to sort the array by store count and display the new favorite stores to the screen. My question is, how can I store that data until it's time for me to evaluate the new standings? You could add store-count as key-value pairs to SharedPreferences http://developer.android.com/guide/topics/data/data-storage.html

I'm kinda new in Prolog and I'm using SWI-Prolog v6.6 to storage asserts in my *.pl file. :- dynamic fact/2. assert(fact(fact1,fact2)). With the code above I can make asserts and it works fine, but the problem is when I close SWI-Prolog and I open the *.pl file again, the asserts i've made are gone... There is a way to make asserts and those get stored even if I close the SWI-Prolog? Sorry about my bad english and Thanks! (: Saving state has certain limitations , also see the recent discussion on the SWI-Prolog mailing list. I think the easiest way to persistently store facts on SWI-Prolog is
