A typing tool using javascript

Demo This typing game demonstrates some basic javascript techniques for DHTML including animation...and can even teach you how to type. Words are created using a typing distance metric, that's the key distance on the keyboard...how far your fingers have to move from the home key. Clck the run button to start, enter the letters in the falling orange block and then the spacebar to get to the next letter group.

Source CodeJust view source to see the javascript. Uses many of the techniques used elsewhere in Datacorner. Comments via Datacorner Rants. Click the helpRant button.
     
Encryption demo

Demo javascript-based AES encryption. Use as a browser-based encryption tool or store encrypted files on the server via JSP.

Source Code the jsp source. For the associated html source, just go to the home page, click the pwProtect button and save the popup to your desktop. You will need a server running a jsp container (tested with Tomcat 4.13) to execute the login functionality. The javascript encryption works just fine without it. any questions, comments via Datacorner Rants. Click the helpRant button.

webmark service benchmark tool
Demo webmark benchmarking tool lets you answer the burning question, "should I entrust operation of my mission critical functions to a remote service?". Provides a stripchart display of ongoing latencies incurred by the service call. Next step, histogram the latencies. And after that, support true web services by uploading a message body as well as the call. And of course, cookie support. Have fun. View the source code. Makes use of 2 jsp's: doCallTime.jsp sets up the display and provides the controls. doCallTime calls doGetTime.jsp which actually makes the call to the remote service and measures the latency.

Source Code the jsp source. Composed of two files:
