Makefile for Java

gnu make How many of you Java programmers have had problems compiling programs? libraries out $ CLASSPATH, kilometric parameters to pass to the Java compiler. Even using development environments for Java, the situation does not improve much. We spend a lot of time paramter and set every time you start filling missing something!

You can avoid all these problems simply by organizing the sources using Java and a Makefile written for that purpose.

Deleting files created by the opening of a store

How many times we've extracting archives and end up with hundreds of files and directories everywhere. This happens when files are created are not including the workbook. What you could do until recently is to remove all new files being careful not to touch the files that were there previously. Now thanks to this little bash script can do this quite automatically and without risk to the system and for our files.

Goldbach's conjecture

A conjecture is a statement as probably true but not yet proven. A vote demonstrated its validity becomes a theorem. Goldbach's conjecture is one of the oldest problems to be resolved, dates back to 1742, was enunciated by Euler to Goldbach and restated as follows:

Every natural number greater than 2 can 'exercise written as the sum of two
primes.

Trying to prove its inaccuracy

At a guess we can perform two types of demonstrations we prove its correctness or its inaccuracy. Obviously one excludes the other. Will try to prove that the conjecture is false to do so just find a counterexample canvases that the statement is false. So in our case, just find a single number which is not the sum of two primes. To find this number will write a program.

Bashnya the evolution of Russian lady

lasca The game, also called Bashne, it spread to Russia in the nineteenth century, the first description dates back to 1875. E 'in some way related to the

Russian Checkers (the starting position is the same), but the rules of capture are completely original. The game has inspired in 1913 the Laska or leave it, designed by the then world chess champion Emanuel Lasker, the difference between the two games is simply the size of the board.

We will see the game first and then a program that allows us to challenge anyone in this game.

Solving Sudoku

We will see together how to write a program to find the solution to a Sudoku.

Review the rules of the game. It is played on a 9 × 9 grid divided into 3 × 3 grids that other regions or call boxes. The sudoku starts with a grid containing numbers already, the goal of the game is to fill the empty cells to the [...]

Volumegain: alignment of the volume of stream

The problem of alignment of the audio

Listening to different audio tracks often perceive different levels of volume. These constant changes in volume between tracks and the next can be very annoying, can cause us to lose concentration and constringerci constantly changing the volume level manually.
The problem affects all those cases where you need to concatenate tracks [...]

ssh / scp: password on command line and shellselect

Why is it wrong

There will be past the head at least once in your life can change the password as an option to the ssh client. So why OpenSSH has not provided?

Some reasons might be these

Not sure if we pass the password as an option will be logged between the commands you type, finds the file ~ /. Bash_history, [...]
