[UPDATE]: If you are trying to remotely connect to your Ubuntu box from Windows computer, then I highly recommend X2Go, which enables you to access a graphical desktop over a low bandwidth (or high bandwidth) connection.

Check my post for more information. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Recently I am working on a research project that requires me to use Ubuntu, so I installed Ubuntu 14.04, the LTS (Long Time […]
When Windows 8 was first introduced, the iconic Start menu was removed. Many users were frustrated by this removal. For instance, you cannot shut down your computer the same way you do in previous versions of Windows: Start->Shut down.

Recently I was trying to install an Ubuntu Server in VirtualBox, and I noticed that my host Windows OS is 64-bit, but VirtualBox does not have options for 64-bit guest OS in the Create Virtual Machine interface. My first thought was I need to install 64-bit VirtualBox, but I was wrong. There is only one version of VirtualBox for both 32-bit and 64-bit host PC.

In my previous post, I shared some tips on creating a strong and secure password in an easy way. Let me recap the steps just in case you forgot. 1. Choose a phrase (about 12-14 characters long without space) that is only known to you, for example, “Ilovepancake!”. 2. Capitalize the first letter of each word, in this case, “l”->”L”, “p”->”P”. 3. Replace some letters with numbers or special characters, for example, “o”->”0″(number zero), “a”->”@”, […]

If you have installed Google Drive or Microsoft OneDrive on your Windows PC, you will notice that Windows search does not find any documents in your Google Drive (or Microsoft OneDrive) folder. The cause of the problem is Windows indexing service didn’t index Google Drive (or Microsoft OneDrive) folder, even though these folders are listed in the index options. So why Windows indexing service failed to index those folders? It is because the permission is […]
