uniqueidentifier

It makes a lot of sense that Android ad SDKs will use Android's the new advertiser id. It seems that you can only get the id by using the google services sdk, as mentioned here: http://developer.android.com/google/play-services/id.html . Using the google play services sdk, requires referencing the google-play-services_lib project, which causes several problems: A lot of SDKs are jars, meaning they can't use google-play-services_lib as is (because they can't include resources). If I only want the advertiser ID, I need to add google-play-services_lib to my project, which weights almost 1 MB. Is

This question already has an answer here: UIDevice uniqueIdentifier deprecated - What to do now? 32 answers Our iOS application is for specific users. So, we used device unique identifier for user identification. This approach works fine till iOS 6, because we are getting same value every time. NSString *strUniqueIdentifier = [[UIDevice currentDevice] uniqueIdentifier]; In iOS 7, above method is retuning different values and we are getting issues in user identification. iOS 7 apis provide following alternate. NSUUID *oNSUUID = [[UIDevice currentDevice] identifierForVendor]; [strApplicationUUID

Is there a way of encryption that can take a string of any length and produce a sub-10-character hash? I want to produce reasonably unique ID's but based on message contents, rather than randomly. I can live with constraining the messages to integer values, though, if arbitrary-length strings are impossible. However, the hash must not be similar for two consecutive integers, in that case. You can use any commonly available hash algorithm (eg. SHA-1), which will give you a slightly longer result than what you need. Simply truncate the result to the desired length, which may be good enough. For

If I were building a blog I could use the blog title as the unique identifier and parse it through the URL. However, what if I wanted to use numbers. You know how twitter has www.twitter.com/username/statuses/9834542? Has anyone figured out a nice way of making this work? using "_id" is out of the question since it's way too long. Alan As long as you can guarantee uniqueness, you're not constrained to using the default "_id" MongoDB supplies. Therefore, it's down to you how you generate this number. If you'd like to store this number inside MongoDB, then you could store it in a separate
