问题 I don't want my database id's to be sequential, so I'm trying to generate uids with this code: $bin = openssl_random_pseudo_bytes(12); $hex = bin2hex($bin); return base_convert($hex, 16, 36); My question is: how many bytes would i need to make the ids unique enough to handle large amounts of records (like twitter)? 回答1: You might considering something like the way tinyurl and other shortening services work. I've used similar techniques, which guarantees uniqueness until all combinations are

问题 After modifying an existing file I would like to find out if the software used to modify the file created and saved the new file (discarding the old one) or changed the original file. Currently I'm using powershell with Get-ChildItem: Get-ChildItem D: -Force | Select-Object Name, CreationTime, LastWriteTime, Length This only works if the software in question didn't reapply the orginal CreationTime in the new file. If it did (like e.g. Excel does when editing existing files) the result would

问题 I am trying to return a list of triples by using a construct query in the Wikidata SPARQL query service. I want all triples of people who have a GTAA_ID identifier.

问题 The function [[UIDevice currentDevice] uniqueIdentifier] Is deprecated in iOS 5 and I found the solution in this project using the MAC address: https://github.com/gekitz/UIDevice-with-UniqueIdentifier-for-iOS-5 Ok, it is solved.

问题 I wonder if there is any way to retrieve, for both a server and a client connected through ssh (OpenSSH), some unique session identifier (let this be USID ). This would be used to restrict the execution of a specific (custom) software (let it be a.exe ), so it can only be executed through a specific ssh session , even if other users (potentially root) have access to that executable: after a ssh session is opened from machine C (client) to machine S (server), machine C (which knows the USID )

问题 I'd like to setup a foreign key to a default membership table but I'm getting an error when trying to define it. I'm using the default aspnet_Users table and also my own Posts table. I'm trying to setup the tables as follows: aspnet_Users UserId (PK) uniqueidentifier UserName nvarchar(256) Posts PostID (PK) int UserName (FK -> aspnet_Users.UserName) nvarchar(256) However, when I try to set this up using the VS 2010 designer, it gives me the following error: The columns in table 'aspnet_Users'
