Running Windows 3.1 in Browser!

26-January-2010 Leave a comment

Michaelv.org is coded in JavaScript and strict XHTML 1.0, with AJAX functionality provided through PHP. It has been tested for compatibility in Firefox and IE. Firefox 2 or 3 is highly recommended, but the site is almost entirely functional in IE 6, 7, or 8. Media Player does not work in IE as IE lacks the ability to dynamically instantiate <OBJECT>.

The file system is stored in SQL and is dynamic. File creation, renaming, deletion, reading, and writing can all be accomplished in real-time and with persistent results. However, for obvious reasons, visitors are not able to make changes to the file system in any way.

The goal of this site is not to create an entirely complete mirror image of Windows 3.1, but rather keep the spirit and omit features when they are not justified by an effort to usability ratio. For example, Notepad lacks a find and replace feature because it is not worth the effort. Where features do exist, every effort is made to present them in exactly the manner that they existed in Windows 3.1.

The developer has also endeavored to put plenty of features in which are not readily apparent, hopefully making the site a fun and long-lasting process of experimentation and discovery. For example, try pressing the keystroke for full screen mode in MS-DOS Prompt.

Windows 7 Devices – Aal is whell

25-January-2010 Leave a comment

To experiment the Driver support in Windows 7 x64, I connected all possible devices at home on my AMD PC.

Windows 7 x64 - Fully Loaded with all my Devices. Behind 5 US... on Twitpic

My Devices in Windows 7 (64-Bit)

Overall all device installation went smooth, with few observations:

1) HTC Viva failed for the first time.  To fix this, I ran Check Updates manually, which installed the x64 Windows Mobile drivers.

2) Nokia 3110c installation went well, but it shows a number of devices under the Unspecified category. This reason is yet “unknown” for me.

3) The amazing part was my old Sony DCR-TRV340, which got installed within 5 seconds.  It didn’t even tried to contact Windows Updates.  This device required a separate Driver CD earlier in Windows XP.  With Windows 7 in-built Windows Video Capture program, I am able to record my Hi-8 videos without any issue. FYI –  this is hooked to Firewire(IEEE 1394) port.

4) I had purchased a Bluetooth USB Adapter (Make – “ENTER”) from Staples last year.  This device came with Trial Version of its Drivers, which troubled me a lot on Windows XP.  This device too got installed without any issues.

5) My old UMAX-5600 USB Scanner could not be installed due to unavailability of its drivers. Has anyone used this device on Windows 7?

Bottomline: Now onwards, there is no need to maintain the Driver CD’s of my Devices

Windows 7 GodMode showing 45 categories and 278 shortcuts

9-January-2010 Leave a comment

Windows 7 has an undocumented feature to create a shortcut which is named as “GodMode” by many Internet Blogs.  This feature is intended to give developers quick access to areas of the operating system.  Below are the steps to create this special shorcut:

1. On your desktop, create a new folder.
2. Name the folder as MyTools.{ED7BA470-8E54-465E-825C-99712043E01C}

Shortcut Icon created on Desktop

In my above example, the word “MyTools” can be replaced with any other text.  The result, you get the following shortcut icon on your desktop.

When clicked, it opens Windows Explorer with long list of shortcuts to almost all areas of operating system operations.   The shortcuts in this folder links to various tools, utilities and interfaces which are already available and can be found in Control Panel.  It just puts them all into one big list and categorises them. You will notice a count of 45 categories and 278 shortcuts.

One can create below listed shorcut folders using the same steps described above. The below folder names are named accordingly to give you a clue as to what each one does:

Excel 2010 Beta – File Save Bug

25-December-2009 Leave a comment

Today, while saving a New Excel Worksheet in Microsoft Excel 2010 Beta, I received the following message:

Unable to save file under a directory with special characters

I was trying to save this file under folder “C:\MyWebsite[Dev]”, which contained special characters “[]“.

To further confirm the bug, I tried to create a New Excel Worksheet from Windows Explorer (using Right Click -> New -> Microsoft Excel Worksheet). Using this method, the file got created successfully. I could even open it (double click), modify it and save it in Excel 2010.

This problem is only appearing while creating a New file in Excel. I have not seen the same behavior in Word 2010.

Does anyone know if this is a real bug or a default behavior of Excel 2010?

Update on 28-Dec-2009:
Further analysis revealed that this issue persists in Excel 2003 too.  Below is the screen shot from Excel 2003 (SP3).

Same issue exists in Excel 2003

Anyone know the reason behind this design?

Mouse turns 40 years

3-December-2008 Leave a comment

The well-known computer mouse will complete its 40 years of journey on this 9th of Dec-2008. The first known publication of the term “mouse” as a pointing device is in Bill English’s 1965 publication “Computer-Aided Display Control”.

On December 9, 1968, Douglas C. Engelbart and the group of 17 researchers working with him in the Augmentation Research Center at Stanford Research Institute in Menlo Park, CA, presented a 90-minute live public demonstration of the online system, NLS, they had been working on since 1962. The public presentation was a session in the of the Fall Joint Computer Conference held at the Convention Center in San Francisco, and it was attended by about 1,000 computer professionals. This was the public debut of the computer mouse. But the mouse was only one of many innovations demonstrated that day, including hypertext, object addressing and dynamic file linking, as well as shared-screen collaboration involving two persons at different sites communicating over a network with audio and video interface.

Since the age of Windows operating system (and also Mac OS), the mouse has become part of computer. The technology era is further making developments with Touch Screen technologies, which may turn the mouse into a history!
