As I remember, when I copied a service class from my previous system. But I got this error striaght away: can't resolve all parameters for InvoiceService: (?). I checked it should be in module class, imported the modules I need for the constructor. Finally, I found in Angular 8, that required @Injectable at the top of class. A silly mistake...

I tried to use a Keychron K8 for a few months. I found some problems in bluetooth connections. I found some times, the connections will drop off. Moreover, if I switches computers, the keyboard need a few seconds to connect(Actually, that is not a big problem). Now unless, I need to use a Mac Mini(a Secondly Computer) then I will use a Keychron K8. Because I do not need to have too many wires. Moreover, if I need to use Mac, I must switch PC and Mac at the same time, In this situation, using Keychron is the best solution and smooth solution.
In the most of time, I will use a Keychron K8 in the wire mode for the office laptop, No doubts, Keychron K8 is a good keyboard. And I will use my Duckey One Mini for my personal PC. Because that is small, my desk still have space to have a small extra keyboard.

I wish to change the format title in header in one of my wordpress websites. I know I can define a custom function to change that. I tried that, that is not working my template. Finally, I found a cleanest and easiest way to do, without writing a single line of code. That is to install Yoast SEO plug-in. This plug-in can allow the user to define page title in header for each page and post. That is very flexible. Moreover, it has a lot of placeholder too, such as site title, page title and post title.

I got New Dell Inspiron 14, which is a brand new laptop. It has an 11th Gen i5 CPU. So, it should be very fresh, with the latest drivers and design. After I used a week, I found its screen is flickering if that is not connected with the power adapter. That is strange. I am worrying that it is a hardware failure. I entered the BIOS and ran the diagnosis test. That is fine. Then I did some google searches. The older models got similar problems after the windows upgrades. The suggested solution is just running the drivers upgrade. However, this is a new laptop, which should be just coming out from the factory not long ago. Well, that is no harm to do a driver update. Then I upgraded all drivers and BIOS. Then that is the problem. Strange, I think that laptop should be already with the latest drivers, but actually, that is not.

Wix and Shopify are very popular. That is a cloud website builder. You can use them to build a website very easily. Even you can hire some professional to do that for you. The main advantage is they are cloud solutions, so you do not need to have a server and maintain the CMS. That is much easier for small business. So, a lot of businesses which are using WordPress are moved to them. However, WordPress is still worth to use. Nowaday, WordPress is very user friendly now, there are a lot of drag and drop style builders for WordPress. For Us, who are with some programming experinces, WordPress is very customizable, it can do the things faster than Wix and Shopify, and we can build extra easily too. Lastly, there are a tons of pre built web templates for WordPress. So I think that is still worth to consider as your CMS.
