Many times managing your azure storage account we all need to manage access keys through the following interface, and in most cases we can manage them safely by using the update on the key rotation. But many times the key to the storage account is accidentally distributed to people, testers, and administrators. Now if you need to manage this storage account more

Android stores and loads local files (internal storage devices) and android storage devices All applications on Android devices have a directory of files placed in the sandbox. Saving the files in the sandbox can prevent other applications from accessing them. The full path of the sandbox directory is/data/ As you can see, each application has a file directory named after this package under/data. This arti

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.

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

Database Design-semi-structured storage and database structured storage 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
