You must use a separate PRIMARY KEY(index_col_name, …) clause. Something like this can be … Read more
As mentioned by others there’s no cross platform way to do this, but on Windows you can do it like this: The Code below checks if the key ‘A’ is down. if(GetKeyState(‘A’) & 0x8000/*Check if high-order bit is set (1 << 15)*/) { // Do stuff } In case of shift or similar you will … Read more
I was able to resolve this with: apt-key adv –keyserver keyserver.ubuntu.com –recv-keys 605C66F00D6C9793 \ 0E98404D386FA1D9 648ACFD622F3D138 Looks like the ubuntu servers also contain the debian keys.

If you use Rails: Example with hash: camelCase to snake_case: hash = { camelCase: ‘value1’, changeMe: ‘value2’ } hash.transform_keys { |key| key.to_s.underscore } # => { “camel_case” => “value1”, “change_me” => “value2” } source: http://apidock.com/rails/v4.0.2/Hash/transform_keys For nested attributes use deep_transform_keys instead of transform_keys, example: hash = { camelCase: ‘value1’, changeMe: { hereToo: { andMe: ‘thanks’ … Read more
You could encrypt the private key with a symmetric key based on the users password. Simply store an additional salt and perform the password “hash” to get a separate key. Then use that as key for encrypting the private key. Note that it is required to use a Password Based Key Derivation Function (PBKDF) such … Read more
Tracing the source code of the 5.1 Source for the View Class. It would seem that dispatchKeyEvent() is the first method called by the system. Overloading it will prevent any and all key events from being called unless the base version is called. dispatchKeyEvent()‘s first move is to attempt to pass the event to an … Read more
There is no “error” if you use more than one key with the same name, but in JSON, the last key with the same name is the one that is going to be used. In your case, the key “name” would be better to contain an array as it’s value, instead of having a number … Read more
