- a little order in the chaos where the mind dwells
|
A while ago I talked about a possible project I wanted to try based on a site I saw some years ago. And so here it is.
It is a speech profiler which at the moment allows someone to get word counts, sentence counts, and see visually sentence density. In addition, one can search for certain words and phrases to see occurrence density within that visual representation. Finally, one can compare those numbers and visual representations between multiple speeches. I plan to at some point add some additional statistic features such as unique word counts, comparisons, and other things as I think of them or get suggestions. posted by dharh 6:03 PM Mar 18th, 2008
As you can see the Java implementation of Step 1 of 15 Exercises for Learning a new Programming Language was more complicated than the C# implementation. This was largely due to one factor. You can't poll whether someone is typing from the console in Java.
The second problem is that you can't use a KeyEvent handler in the console, which would the second easiest solution to attempt. Finally a third problem is that by using an event handler you essentially need to use threading so that the loop doesn't interfere with the handler and you are able to interrupt properly. If there are better solutions I'd be very interested to see them. package learn2Java1;

1. Display series of numbers (1,2,3,4, 5....etc) in an infinite loop. The program should quit if someone hits a specific key (Say ESCAPE key).
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
namespace lrn2CSharp1
{
class Program
{
static void Main( string[ ] args )
{
for ( int i = 0; ; i++ )
{
if ( Console.KeyAvailable && keyPressHandler( Console.ReadKey( true ) ) ) break;
Console.Write( i + " " );
Thread.Sleep( 250 );
}
}
protected static Boolean keyPressHandler( ConsoleKeyInfo input )
{
if ( input.Key == ConsoleKey.Escape ) return true;
return false;
}
}
}

So I saw this page which gives a list of 15 Exercises for Learning a new Programming Language. I thought, this could also be a good way to compare different languages. In that spirit I'm going to do just that and try to complete the list in different popular languages. To start with I will do them in C# and Java.
As it turns out I'm much less familiar with C# than Java so it will also be a learning experience as the original article had intended. You can see the progress in Programming. posted by dharh 6:43 PM Feb 10th, 2008
function trim(str) {
var str = str.replace(/^ss*/, ''),
ws = /s/,
i = str.length;
while (ws.test(str.charAt(--i)));
return str.slice(0, i + 1);
}

This guy seems to have the right idea on why people would ever choose open source.

v2.0.134 (19 Mar 2011) New Versioning Skipped 1.0 because the previous cold fusion version for all intents and purposes was 1.0 even though it never made it past the beta stage. I am using an auto versioning system with visual studio. Which means for the most part the third number, the number of compiles, is the main way to tell which version is which. The second number will still keep track of major versions, but I don't really foresee using it much. neTodo.net Released
