IT Tips & Tricks

Rooting your Android? What is rooting?? Unlocking the bootloader ??? Confused! Root The term root in the IT world initially came from the UNIX / Linux Operating Systems.  New stand-alone Android is built on top of the Linux OS. The root is equivalent to Administrator in Windows. So root access is administrative access to the file system. The root can add, edit and delete system files. The root has the ability to change system files such as installing a system-wide ad-blocker by modifying the host file on your device, or uninstalling system apps, such as bloatware that comes pre-installed on your device. Without the root, one can only see files in the root directory instead of editing them.

It initializes the Linux kernel and loads all the necessary components required to boot into the Android. And it manages direct access to the device's partitions. Un

Google Play Store: error retrieving information from server df-dferh-01 I have an Amaze 7 Android tablet. It is an old tablet with Android 4.1.1.

Change the password length requirement in Umbraco This solution will work with Umbraco 8.xx versions. Previous or newer versions may need some additional or fewer changes.  In Umbraco default password length is 10, and need to provide a valid email address for the user name.   If you are developing or designing a website using Umbraco and testing it you may need to shorten the password length or use a short username in your development website to save time. (NOT in the production site) Changing default password length in a new installation This method is for a fresh Umbraco installation. For an existing installation, there is some extra work to do. I will discuss it later. Lots of people have an issue with changing the configuration to suit this requirement.  First, we will look at the issue. Open the  Web.config file and go to the following section <!-- Membership Provider --> <membership defaultProvider = "UmbracoMembershipProvider" userIsOnlineTimeWindow = &quo

Renaming or Replacing multiple file names in a folder - The Fast way -Windows 10 Suppose we have many files in a folder with similar pattern and we want to rename all of them. Doing this manually using explorer or command prompt is very time consuming. For example we have following files stored in d:\Products\ folder:      scean1-160_x_90.jpg      scean1-240_x_135.jpg      scean1-320_x_180.jpg      scean1-480_x_270.jpg      scean1-640_x_360.jpg      scean1-960_x_540.jpg      scean1-1280_x_720.jpg      scean1-1920_x_1080.jpg      screen1-2560_x_1440.jpg      screen1-3840_x_2160.jpg      scean1-5120_x_2880.jpg We want to change the common string pattern "_x_" to "x". Easiest way to do this in Windows 10. Useing Windows Power Shell open the folder and execute the following command: get-childitem  | foreach { rename-item $_ $_.Name.Replace("_x_", "x") }

Today I am editing the Articulate “VAPOR” theme installed in a hosted website. Initially I edited it from the Umbraco dashboard, save changes and tried to see the changes by refreshing the actual web site. But it didn’t work. I tried almost all other options, clear the cookies, restarted the application pool from the Plesk Admin Panel. Nothing work. Even though I have installed a previous version of Umbraco to a client, I am not sure if all .css files shown in the dashboard are directly reading from/ writing to the physical file or stored in the database.  Then to check that I connected to the site via my favourite FTP client WinSCP (I am not using the FileZilla any more.), and I can clearly see the changes I have made from the Umbraco admin dashboard are saved in to the actual file. Then as everyone does, I google-binged  the internet, and found that in several forums that so many people have the same issue with other  Umbraco versions and of course with some none Umbraco web sites as
