Consider the following: class Base { public: virtual std::string getName() = 0; ... }; class Derived1 : public Base { public: static std::string getClassName() { return("Derived1"); } std::string getName() { return("Derived1"); } ... }; class Derived2 : public Base { public: static std::string getClassName() { return("Derived2"); } std::string getName() { return("Derived2"); } ... }; The idea is that if you have the derived class passed as, say, a template parameter, then you can get its class name via getClassName , while if you have it passed as a pointer to base class, you can get the name

According to the official Marshmallow docs, it's recommended to declare a Schema and then have a separate class that receives loaded data, like this: class UserSchema(Schema): name = fields.Str() email = fields.Email() created_at = fields.DateTime() @post_load def make_user(self, data): return User(**data) However, my User class would look something like this: class User: def __init__(name, email, created_at): self.name = name self.email = email self.created_at = created_at This seems like repeating myself unnecessarily and I really don't like having to write the attribute names three more

I'm using Soda to write Selenium tests in Node.js and I have a situation where I have to press the down key several times. The code currently looks like this: browser .chain .setSpeed(200) .session() .open('/') .click("id=save") .focus(editor) .keyDown(editor, '\\40') .keyDown(editor, '\\40') .keyDown(editor, '\\40') .keyDown(editor, '\\40') .keyDown(editor, '\\40') .keyDown(editor, '\\40') .keyDown(editor, '\\40') .keyDown(editor, '\\40') .keyDown(editor, '\\40') .keyDown(editor, '\\40') ... How could I DRY this up? Just using a loop like this does not work with this lib: var b = browser

Android's Content Provider must have : At least one authority must be specified. So for example in Google's samples android-BasicSyncAdapter AndroidManifest.xml there is <provider android:name=".provider.FeedProvider" android:authorities="com.example.android.basicsyncadapter" android:exported="false" /> Then to implement this CP one need to define the same String inside the CP like in android-BasicSyncAdapter FeedProvider.java CONTENT_AUTHORITY public static final String CONTENT_AUTHORITY = "com.example.android.basicsyncadapter"; As we have to define this String twice, isn't this basically
