In the past, when I used EF Core 1.1, I can use String.Contains() in where to preform string like search.
Such as:
_db.Customers.where(x=>x.FirstName.constains("michael"))

But we moved to EF Core 3.0. I found that is a problem, I got the exception regarding the LINQ translation. This sort of helper function in where is no longer support.
I need to re-write the query, like this:
_db.Customers.Where(x=>EF.Functions.Like(x.FirstName, "%michael%")
)

These few months, I am working on a project which is using Angular Material Framework. Its functions are very rich. It makes UI very nice. But you need to have a very tiny html template. I found my Radio Button is not working. You cannot select the values. After several trial and error, I found the mistakes I did is placing mat-radio-group elements in a mat-form-field element. Even the page is still rendering the nice UI, but the functions are not working. The solution is simple, I just need to change mat-form-field to a div!

Angular Material framework is very useful. It will make your SPA look like a native mobile app. It works fine in desktop, tablet and Mobile. However, I found sometimes, the styles are broken and the Animations does not working anymore. I did a research on the internet, a lot of people are saying that is because the style files are not applied. In my situation, it does not sounds that is the case. Finally, I deleted the elements one by one. Then I found it caused by the malform elements

A lot of programmers like to use mechanical keyboards. The type of keyboards got better experiences on typing and more durable than the traditional membrane keyboard.
For mechanical keyboards, there are several different types of keyboards switches to choose. Each type of switch will give you a different typing experience. I have used the top 3 popular switches.
Firstly, I tried Cherry MX Blue. A lot of people call it "Typist Switch." It got a "clicky" sound when you are typing. But I found that it is noisy, and the keys are a bit "hard."
Secondly, I bought a keyboard with Cherry MX Red afterward. I like that. It has not the "clicky" sound, and the keys are much softer, more comfortable for typing. That is very good.
Recently, I bought a ducky keyboard with Cherry MX Brown. I found this type of switch is my most favorable switch. The keys are soft too, and it got a bit "clicky" sound, but not very noisy. I will award this type of switch the name, "Programmers' Switch."

Yesterday, I had a chat in a law firm at Southside of Brisbane. I suggested they can provide some initial consultations online. They accepted my suggestions. After the conversation, I found a lot of professional service providers such as Accountants, lawyers, and property valuers, do not require a physical office location. Nowadays, a lot of things can do it online. The customers can make the inquiry online via email or Whatsapp. A lot of face to face meetings can reduce. The professionals can work from home too because they need a computer to work. We can communicate with our colleagues online. There are live chat tools, such as MS teams and slack.
Yes, they still need to meet the people in person. For example, you need to verify your customers' identity or witness their signature. Then we need a sort of co-working space to hire a meeting room. Of course, for colleagues, we need to have some team meeting activities, then we go to a restaurant or a coffee shop for this purpose. Yes, I know if you need to pair up someone for a project, for example, pair programming or brainstorming. That is better to work in the same physical location. Then the co-working space is the solution again. You can hire some hot desks in there.
I think the demand for co-working spaces will be increasing in the current trend, rather than the needs of an office.
