Convert DEB to RPM or RPM to DEB Package

Posted on April 3, 2013April 3, 2013 by David Saliba

You can convert DEB file to RPM package and RPM to DEB package using alien command, if you have a *.rpm file that you want to install on a Debian or Ubuntu.

Convert RPM to DEB

Install alien command on Ubuntu as mentioned here:

# sudo apt-get install alien

Now, use alien command to convert rpm to deb file,

# alien clamav-0.92.1-1.el5.rf.i386.rpm

clamav-0.92.1-1.el5.rf.i386.deb generated

Finally, Install deb packages using the dpkg command,

# dpkg -i clamav-0.92.1-1.el5.rf.i386.deb

Where,
-i = install a package

Convert DEB to RPM

Use alient -r option to convert a deb file to rpm file.

# alien -r clamav-0.92.1-1.el5.rf.i386.deb

clamav-0.92.1-1.el5.rf.i386.rpm generated

Once you generate the rpm file, you can install it on Red Hat, Fedora or CentOS.
Finally install rpm,

# rpm -ivh clamav-0.92.1-1.el5.rf.i386.rpm

Where,
-i = Install RPM
-v = Install in verbose Mode
-h = Print 50 hash marks as the package archive is unpacked

.Net Restart an ASP.NET application programmatically without editing the web.config

Posted on March 28, 2013April 1, 2013 by David Saliba

Windows oddly.. but a good friend found this it’s on her site:

http://rochcass.wordpress.com/2013/03/28/restart-an-asp-net-application-programmatically-without-editing-the-web-config/

to quote:

Several times I would be working on a site and some data would not change due to session variables or the .NET cache. This can’t be eliminated by clearing the browser cache but would need the whole ASP.NET application to be restarted to clear all sessions and cache. A traditional way of doing so is to edit the web.config slightly (a space, comma, fullstop would do the trick) … however this was happening often so I decided to restart my application automatically through my code. To do so, I used the Global.ascx on application_start and added this simple line of code which restarts the ADO.NET application:

System.Web.HttpRuntime.UnloadAppDomain();

Thanks Roch..
