This post is for those who had some experience with Linux or had tried Linux before, but never made up mind to switch to it. Linux has become better and better in every aspect of the operating system, especially with the new release of Ubuntu 17.10 and Linux Mint 18.3, I think it is the right time to dive into Linux and eventually switch to Linux from Windows. However, if you think you are still not ready to switch to Linux by going cold turkey, I will show you some ways that help you to gradually ease into the Linux […]
I have a old HTC One M7 smartphone sitting there for two years and both HTC and Sprint have stopped releasing updates long time ago, so it is still running Android 5 Lollipop. There is no trade-in value for this phone and I feel like it is a waste to throw away the phone, so I decided to root it and install a custom ROM to see if it will work. After some research online I successfully installed CandyRom, which is a custom ROM for Android 7 Nougat. Now my old HTC One M7 is running smoothly with all the […]
You can add database tables and stored procedures in your Entity Framework data model, but you may encounter an ArgumentException error in Visual Studio when adding a stored procedure: An exception of type ‘System.ArgumentException’ occurred while attempting to update from the database. The exception message is: ‘Identifier is null or empty’ The error message is confusing because the actual cause of this error is that the stored procedure does not have a return value. In order to add a stored procedure in EF data model, EF will first try to execute the stored procedure in a special environment (so it […]

Would you like to read an inspirational message from the Bible when you turn on the screen of your phone? I just made two lock screen images for Samsung Galaxy S6 and Note5 with the Bible verses: Philippians 4:13 and Proverbs 16:3. Here is what it looks like on my phone: If you want to download the images and use them for your lock screen, you can click here or the “Free Stuff” link from the top menu. I hope you like them.
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 developed on photo prints. Some of the photo are securely stored in various albums but the rest are randomly scattered in different boxes and it […]
I have a habit of keeping my computer system as up-to-date as possible, including Windows updates and hardware drivers, so when I noticed there is a new version of BIOS for my HP Envy laptop the other day, I started the update process right away without giving much thought about the potential danger of updating the BIOS. The download of the BIOS update utility was smooth and the update process completed without interruption. Supposedly, the computer should reboot to finalize the BIOS update, but unfortunately my computer stuck with a black screen. The power button was lit but the computer did not respond […]
If you are in the Windows Insider Program and later on decided to opt out, you can choose to roll back to the last stable release you installed. However, the rollback may cause a very annoying error as show in the screenshot above: Selected boot image did not Authenticate. Press <Enter> to Continue. When you press <Enter>, you computer will shut down and the error repeats when you restart your computer. Based on my investigation, this seems to happen especially to HP computers, since my laptop is HP Envy, I got the exact error message after I tried to opt out […]
