Last time, I was initially exposed to the mounting problem of Android USB client, so I wrote the first article about the feelings. There are still some problems in many places, some of which are not clear enough, so I want to continue writing.
First, the last verification shows that the device can be mounted, but only one storage device can be mounted at a time.
Secondly, what I said last time about the driver of the device node, there is also a probl
Windows Phone 7 supports data access in the following ways: XML, isolated storage [independent storage], and cloud [cloud storage]. Windows Phone 7 does not support local storage.
Database APIs can be used.

This article mainly aims to write some thoughts and insights on storage, because some things have been practiced by myself, so I feel more deeply, technically, I still think that the implementation is different from others' code.
Let's assume a library. If we say that books are the data we want to put, how can we put them. The best way to do this is to drop it inside and then there is no rule, so that every time we look for a book, we will be exhauste
(1) What is cloud storage?Cloud storage is the ability to store your data on a remote server.This means that you can remotely store data such as documents, photos, music and videos without having to occupy physical space or on the home and company computers. There are two options: public cloud: Public cloud storage allows you to share space on a virtual host with
Talk about how to create a file share in an Azure storage account and mount it on an azure VM today. (By the way, the Chinese Azure official documents can be translated, literal translation of global Azure, the technical documentation of the calibration is not good)We'll start by creating a test VM on Azure, for reference: http://gshao.blog.51cto.com/3512873/13448461.

Http://www.cnblogs.com/xbinworld/p/4273506.htmlSparse matrix refers to the matrix elements are mostly 0 of the matrix, in fact, the actual problem of large-scale matrices are basically sparse matrices, a lot of sparsity in 90% or even more than 99%. So we need to have an efficient sparse matrix storage format. This article summarizes several typical formats: Coo,csr,dia,ell,hyb.(1) Coordinate (COO)This is the simplest of a format, each element needs t

Business scenario: the user fills in some documents, reports them, and approves them. There are several fields in the document that need statistics, and the business is not complicated.
In a seemingly simple scenario, when the developer came up with the PDM design, I was shocked. There were nearly 70 tables, each of which had more than

Real-time SSD is best; SAS io is faster; SATA is the cheapest and should be used as a storage server (low frequency of access)
