I just created a Hangman app (same game mechanics mostly) using Java. I did this mainly to test my knowledge in OOP design/coding. I'd like to know your thoughts on my code
The whole project is on Github
I would really appreciate the comments and criticism!

private static BufferedReader consoleR... |
This is my first attempt at Clojure! Apart from all game related issues, how is my code? Is there anything I can do to make it more idiomatic?

This is an assignment for an intro to Java course. It works with the test case given, but I would like to know if there is anything / a lot of things that should be different or could be better.
Specification:
Write a Java application that accepts 5 “valid” numbers from the user.
A valid number is between 50 and 100 ... |
Link to problem.
A number chain is created by continuously adding the square of the
digits in a number to form a new number until it has been seen before.
For example,
44 -> 32 -> 13 -> 10 -> 1 -> 1
85 -> 89 -> 145 -> 42 -> 20 -> 4 -> 16 -> 37 -> 58 -> 89
Therefore any chain that arrives at 1 or 89 will become stuck... |
I had to do this in a course a while back: make {1,2,3,4,5,6,7,8,9} into {{1,2,3},{6,5,4},{7,8,9}}. When doing it, I just made the inner for-loop do all the work. But most of my friends had a Boolean and an if-statement to chose between a forward or reverse loop.
Which is more optimal and which is more readable?

I've written a little command-line utility for filtering log files. It's like grep, except instead of operating on lines it operates on log4j-style messages, which may span multiple lines, with the first line always including the logging level (TRACE, DEBUG etc.).
Example usage on a file short.log with contents like th... |
