Reusable Code Snippet Make a given number odd or even

There are times when you need to make sure your counter starts at an odd or even number. Even is pretty simple - `counter = counter + modulus(counter)`. If counter is even it stays, if it's odd it gets incremented by 1. Odd is a bit more complicated - `counter = counter + modulus(counter + 1)`, If counter is odd it stays, if it's even it gets incremented by 1. if you're in danger of counter being the max value you can always subtract instead. These basic algorithms should work for any language that has a modulus operator/function. I've included …

Hi all, I have an application which saves data (books details like book title, author and location) to a mySql db and performs CRUD operations. I thought I'd use hibernate to take care of the ORM side of things and everything was OK when it came to create a record, but for RUD operations I had an issue. If I'm a user, I'm likely to be willing to find a book by its author, title or location, certainly not by its ID and yet as far as I can see, hibernate uses IDs for these kind of operations. I dug …

Hello, I am learning Tkinter. As a part of the learning process I am building a Notepad clone in order to become familiar with Tkinter widgets. I am pretty close to completing it - I added about 90% functionality to the application - but I face two problems: 1) The text widget has a default fixed size (80x25 chars I believe). If I resize the root window at a greater size, the text widget stays at the initial size. This is an undesirable behavior - I expect/want the text to resize along with the root. Now, I came with something …

I put together this little demo that adds some animation to the effects to give a hint of the potential.

So: Which programming language (besides assembly) is the most effective to use in this configuration when I want to do calculations/modelling trying to find the least number of combinations to fullfill some predefined conditions. More specific I have i.e. 5 sets of combinations each containing three different states: A, B and C. This gives me a total number of 243 combinations. Theoretically it is possible to reduce this number of combinations to 23 so that no matter what combination of the original 243 you …
