git error: remote origin already exists
Sometime when we initialize the Local Repo, we get error: remote origin already exists.
The following step is solution.
Initialize the current folder as a Git repo:
bitnami@debian:~$ git init
bitnami@debian:~$ git remote add origin [email protected]:username/repostioryname.git
Then, error occurs:
error: remote origin already exists.
We need to remove the older origin by:
bitnami@debian:~$ git remote rm origin
Then, add the origin again:
bitnami@debian:~$ git remote add origin [email protected]:username/repostioryname.git
Add files:
bitnami@debian:~$ git add .
Commit with the descriptive message:
bitnami@debian:~$ git commit -m "Comment message"
Push the changes:
bitnami@debian:~$ git push -u origin master

VMware vs. Virtual Box
VMware vs. Virtual Box: Comprehensive Comparison
Some conclusion:
- If you need a free virtualization solution for a desktop, you can select VirtualBox.
- If you need to have a free virtualization solution for running VMs on a server, select VirtualBox or VMware ESXi Free Edition.
- If you need an ultimate solution for desktop with extended 3D graphics support and a wide list of settings, select VMware Workstation (or VMware Fusion for Mac computers).
- If you need a free virtualization solution that only needs to run VMware VMs on desktop with basic options, you can select VMware Player.
- If you need maximum integration between a VMware desktop solution and a VMware vSphere (vCenter server, ESXi hosts), select VMware Workstation or VMware Fusion Pro. You can use VMware Workstation or Fusion Pro for connecting to vCenter Server or ESXi host remotely, and can manage virtual machines residing on these resources. VMware provides a free VMware vCenter Converter for converting VMs of the Workstation format to VMs of the ESXi format (and vice versa).
- If you have an old computer with a processor that does not support hardware virtualization technologies, select VirtualBox, which provides software virtualization.
- If you need the ultimate enterprise-grade solution for deploying multiple servers, running a high number of VMs, using clustering features, etc., select VMware vSphere based on ESXi servers with vCenter.
