Turn your old computer into a Chromebook for free

I got a new Lenovo ThinkPad T480S with less than $700 this holiday season to replace my HP Envy 15 but I don’t want to throw the old computer away because it is still working well, so I decided to keep it as a test computer. I can use it to test the last release of various Linux distros, such as Ubuntu 19.10, Fedora Workstation 31, elementary OS 5.1, Zorin OS 15, and more, or […]

Cannot create initial migration with dotnet ef command in .NET core

By Jason Groce –, Public Domain, Link The new .NET Core 3.0 was released on September 23, 2019, with lots of new features and new changes. Often times, those new changes will not cause any trouble but sometimes they do.

How to Uninstall VMWare Workstation Player 12 in Windows 10

Windows 10 is a great operating system and works great…oh well at least when it’s working it works great. When it’s not working, you will probably be banging your head on the wall and yelling why. Recently I just had a moment like that. I was using VMWare Workstation Player 12 and decided to upgrade to Player 14, so I need to uninstall Player 12 first. It should be a simple task in Windows 10, […]

Digitizing your photo prints with Google PhotoScan in one tap

Over the years I have taken many pictures to capture various precious moments in my life, such as the birth of my children, their first steps, and the first day of school etc., and the memories captured in the pictures bring me great joy every time I look at them. I didn’t have a digital camera 15 years ago (let alone a smartphone with good camera feature), so all my pictures taken back then were […]

Zorin OS helps users to switch from Windows to Linux

I am not going to waste on explaining what Linux is, why/how to use it. You can Google it and you will find so much information online. Because Linux is open source and everyone can modify and contribute to it, there are many versions of Linux, and each version is called a Linux distribution, or distro in short. If you are not happy with Microsoft Windows OS but don’t want to switch to an expensive […]

Google indexes HTTP site as HTTS, how to fix it?

A few months ago, I decided to switch my hosting provider from Arvixe to and after the switch I decided not to continue to use SSL for my site, so I terminated my SSL certificate. Within a week, I noticed that my page views have dropped tremendously, almost to single digit. After some investigation I noticed that Google still indexes my site as HTTPS instead of HTTP, even though I don’t have SSL certificate […]

Grav is a file-based open source Content Management System (CMS) and is developed by RocketTheme, which means Grav doesn’t use a database. Content and configuration options are all stored in flat files on the server. The main focus of Grav is speed and simplicity. Because of this, I would like to give it a try to see if how easy and simple to use it, especially for small business and non-profit organizations where techinical resource […]

Resurrection of Windows Live Writer: Open Live Writer

The famous blogging provider recently released a desktop app for customers managing their blogs, and this reminds me an old and discontinued desktop blogging application I used before: Windows Live Writer, so I did some search and happily found that it has come back to life. Windows Live Writer is a desktop application from Microsoft for blog publishing. It was first released in 2007 and then became part of the Windows Live Essential […]

Google Inbox by Gmail opens to public but still missing two important features

I have been using Google’s new email app called Inbox by Gmail since its first invitation-only release and I have to say I am a big fan of it, and I think it is the best email app so far. Its elegant and mobile-friendly design makes it so easy to check and manage your email inbox, and it also goes beyond email by integrating your calendar, reminder, and other stuff in your account to make […]
