Deny CreateBucket in S3 unless AES256 Encryption Checked

阅读更多关于 Deny CreateBucket in S3 unless AES256 Encryption Checked

问题 I have been trying for the better part of a day. I am, as an administrator, attempting to require users to check the "Automatically encrypt objects when they are stored in S3" button (AES256) when creating their S3 buckets. I've tried about everything can think of. So far, I have only gotten 2 separate results. As a test user, I am either allowed to create buckets (with or without checking encryption), or I am denied (with or without checking encryption). The last effort has resulted in the

And in around advice, I want to wait a result from the Receiver App and taking an action to the callMethodA() method like cancelling its execution(by returning null ) or

Concise way to enforce implementation of factory in Scala

阅读更多关于 Concise way to enforce implementation of factory in Scala

问题 Let us assume we have a trait T . What is the best way to achieve the following: Everybody who writes an implementation of T should be forced to provide a possibility that allows a parameter-free initialization of T , i.e., we probably have to enforce the implementation of a configurable factory. All logic/data that only depends on the actual initialization parameters (of a certain implementation A of T ) should be handled/stored centrally, but should be available in both the factory and A .

Someone know if there's a programmatically way to use a specific defined APN on the device which is not the default one? Thanks. patthoyts You can programmatically query and set the preferred APN using the uri content://telephony/carriers/preferapn . To set a new preferred APN you have to pass in the database ID of an existing APN entry. The following function can do this if you pass in the display name of the APN (eg: setPreferredApn(context, "Giffgaff"); ) public static final Uri APN_TABLE_URI = Uri.parse("content://telephony/carriers"); public static final Uri APN_PREFER_URI = Uri.parse(

Is it Possible to Enforce Data Checking in MySQL using Regular expression

阅读更多关于 Is it Possible to Enforce Data Checking in MySQL using Regular expression

问题 Suppose I have an attribute called phone number and I would like to enforce certain validity on the entries to this field. Can I use regular expression for this purpose, since Regular Expression is very flexible at defining constraints. 回答1: Yes, you can. MySQL supports regex (http://dev.mysql.com/doc/refman/5.6/en/regexp.html) and for data validation you should use a trigger since MySQL doesn't support CHECK constraint (you can always move to PostgreSQL as an alternative:). NB! Be aware that
