• How do you get the logical xor of two variables in Python?

  - by Zach Hirsch

  How do you get the logical xor of two variables in Python? For example, I have two variables that I expect to be strings. I want to test that only one of them contains a True value (is not None or the empty string): str1 = raw_input("Enter string one:") str2 = raw_input("Enter string two:") if logical_xor(str1, str2): print "ok" else: print "bad" The ^ operator seems to be bitwise, and not defined on all objects: >>> 1 ^ 1 0 >>> 2 ^ 1 3 >>> "abc" ^ "" Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unsupported operand type(s) for ^: 'str' and 'str'

• Can I make PDOStatement->fetchObject not use non-member variables?

  - by threendib

  Lets say I have a class like this: Class User { var $id var $name; } And I run a query using PDO in php like so: $stm = $db->prepare('select * from users where id = :id'); $r = $stm->execute(array(':id' => $id)); $user = $r->fetchObject('User'); If I vardump my user object it has all kinds of other fields in it that I have not defined in the User class. Obviously I could make my query specific so that it only gives me back the fields I need/want. But if I don't want to do that is there any way to make this work the way I want it to? I like the idea of fetchObject, because it's one line of code to create this object and set member variables for me. I just don't want it to set variables I haven't defined in my class.

• What reasons are there to place member functions before member variables or vice/versa?

  - by Cory Klein

  Given a class, what reasoning is there for either of the two following code styles? Style A: class Foo { private: doWork(); int bar; } Style B: class Foo { private: int bar; doWork(); } For me, they are a tie. I like Style A because the member variables feel more fine-grained, and thus would appear past the more general member functions. However, I also like Style B, because the member variables seem to determine, in a OOP-style way, what the class is representing. Are there other things worth considering when choosing between these two styles?

• Stopping the manipulation of variables used for data collection?

  - by Ruinous

  I am working on a project in java and I was hoping to be able to collect statistics from the client and a possible problem that I fear will occur is the manipulation of the variables used for collection which will lead to illegitimate statistics. Is it in any way possible to prevent the manipulation of variables or is it always possible? For example: I want to log the actions made per hour from the client. The variable acting as a counter for the amount of actions performed is manipulated and a much larger amount is added to the counter. This data is then uploaded to the server (Of course using a multi-tier architecture to prevent even more possible problems) and considered 'legit.' Is there any way to prevent this?

• Does anyone else think instance variables are problematic in database-backed applications?

  - by Ben Aston

  It occurs to me that state control in languages like C# is not well supported. By this, I mean, it is left upto the programmer to manage the state of in-memory objects. A common use-case is that instance variables in the domain-model are copies of information residing in persistent storage (i.e. the database). Clearly this violates the single point of authority principle, and "synchronisation" has to be managed by the developer. I envisage a system where instead of instance variables, we have simple public access/mutator methods marked with attributes that link them to the database, and where reads and writes are mediated by a framework that decides whether to hit the database. Does such a system exist? Am I completely missing the point, or is there some truth to this idea?

• how does tomcat like web container handle struts 2 variables ?

  - by mobby1982

  i am a newbie . i have a question regarding struts 2 framework and tomcat . i know that each request has it own thread , but my question is are the global variables defined in struts action shared amongst requests. for ex: if i have a global variable named say int pageNo; and i am using in say method called paginationAll() can i use the same variable (pageNo) for another method called say paginatonMaterialAll() in the same action or does each thread has its own set of variables even though globally defined?

• Shouldn’t Bind() pass child control’s values to GridView before Page.PreRender?

  - by SourceC

  hello, For controls such as the GridView, DetailsView, and FormView controls, data-binding expressions are resolved automatically during the control's PreRender event But doesn’t data source control perform updates prior to Page.PreRender event? Meaning, shouldn’t Bind() pass child control’s values to GridView ( so they can be passed to data source control as parameters ) before data source control updates the data source, thus before Page.PreRender event? thanx

• Is it possible to bind arrays of literals in sqlite3-ruby?

  - by willb

  I'd like to execute the following sort of query through sqlite3-ruby: SELECT * FROM foo WHERE bar IN (:items) and bind :items to one or many literals. Is this possible? The obvious technique of passing the list of literals as an array as follows doesn't seem to work: db.execute("SELECT * FROM foo WHERE bar IN (:items)", :items=>[3,1]) (In the above example, only the first value in the array is bound to :items.)
