How to format floppy disk to 720K in Windows

Microsoft has officially removed support for formatting floppies to 720K since Windows XP. For majority of people floppies (especially 720K ones) have long been a thing of the past. However, if you do find yourself in a situation where you need a floppy to be formatted to 720K, you can still do it through command line.

Open command line (Start -> Run -> cmd), insert a floppy, and enter the following in command line:

FORMAT A: /T:80 /N:9

This will format your floppy to 720K. Couple of things to be aware – first, in order to be able to format floppy disk to 720K, you need to cover the hole in lower right corner (you can use masking tape), and second, if you are using a USB floppy drive, this might not work due to most USB floppy drives not supporting reading / writing 720K format.

How to setup free source control under Windows

If you are doing any serious software development, source control software becomes an important tool.
Fortunately, you can set up a source ontrol solution on your home network for free.

To set up source control, you will need a repository server, and client tools to connect to repositories, do check outs and check ins and so on. For server software, I’ve used VisualSVN for Windows. For a client, I have used TortoiseSVN for Windows.

To set up VisualSVN, download install package and run the installer. Set up straight forward and soon you’ll have your server up and running. You can use VisualSVN Server Manager to browse and manage user security and repositories.

To set up a client, download TortoiseSVN install package and run the installer. TortoiseSVN integrates with Windows Explorer, so handling of check outs and check ins becomes very easy. For connection settings, use details of the server that you have set up.

This is a great free solution that gives you professional level source control. VisualSVN is based on Subversion, which is a widely used open source platform.

IIS 6 – eurl.axd file not found error

If you are running IIS 6 and ASP.Net, you may get eurl.axd file not found error when trying to browse websites you have set up in IIS.
Lets say your default document is set to Default.aspx, so if you browse to http://myserver/mywebsite you would expect to be redirected to Defaul.aspx, but instead you get eurl.axd error.
The problem is caused by ASP.Net 4.0 extensionless URL feature. To resolve this issue, you’ll need to disable extensionless URLs. This is done via registry.

1) Back up your registry

2) Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ASP.NET\4.0.30319.0\

3) You should see EnableExtensionlessUrls setting. Edit and set the value to 0

4) If you don’t see EnableExtensionlessUrls, just create it with a value of 0

5) Restart IIS

Mac OS X App Store – “Your device or computer could not be verified”

Some of you may have tried to download updates from App Store, only to receive a message “Your device or computer could not be verified. Contact support for assistance”.
Solution is to delete network preferences file, which will then get recreated after restarting the computer.

1) Make sure you are logged in as the administrator

2) Open Finder and go to /Library/Preferences/SystemConfiguration

3) Delete file NetworkInterfaces.plist (back up the file first for just in case)

4) Restart your Mac

5) After restart, go to App Store and the error message should be gone
