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.

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

• neTodo has been converted from Cold Fusion to .NET
• You can register an account, it's now open to everyone.

JQuery

• Now uses JQuery 1.4.2, will upgrade to 1.5.1 shortly after done with some testing
• The Debug Console has been added to the top. Don't be alarmed, this is here for me to keep an eye on javascript until I am satisfied enough to turn debugging off.
• Framework added to support neTodo Console. This is not to be confused with the debug console, but rather will be used to more quickly manipulate neTodo in a CLI rather than the GUI.
• Added the timepicker addon to make it easier to set due dates for todo items

Features

• Hashtags finally arrived to take over the role of labels. Simply use '#' anywhere in your todo description to add a hashtag to your todo item.
• A list of all your hashtags can be seen on the left menu area under the Lists menu.
• Click on a hashtag in your menu to see all todo items with that hashtag
• A list of all your todo lists can be seen on the left menu area.

Known Issues

• When you click on a hashtag on the left menu you lose your List state which means adding a new todo item will go to the Global List.

Todo List

• Add Prefs page
• Add way to add additional notes and uploads to a particular todo item
• Add @ Mmentions to todo items. This should link to twitter
• Add @@ Push to add todo items. Which would add todo items to _other_ users todo lists. The form is @@dharh ##List Add \@@ Push to add todo items. @@dharh Add ability to push todo items to another user using \@@dharh %projects #neTodo
• Add \ escape character.
• Add ## List to add todo items. This is shorthand for putting a new todo item to a particular list, primary use would be the neTodo Console but can be good for regular Add Todo Box. Use '%' instead.

v0.2 (14 Aug 2009)

Update to JQuery and Preferences Backend

JQuery

• neTodo will now use JQuery 1.3.2

Preferences
