mama | 妈妈再也不用担心我的 macbook 发烫之超级偷懒计划

I need to replace whatever expressions in between 2 patterns of JSON file, those patterns are multi occurrences and I would like to replace them only once by my choice (let's say in the 4th occurrence out of 6).

I've created a sed expression that works when I have only one occurrence in the file, but when adding more than one it is for some reason doesn't work when trying to replace the second occurrence.

This is my sed:

So, I've a command set on my bot that whenever someone types "/planeidea" it sends the name of a plane, however, i've like 300 lines of names of planes. (I reduced it, so you can see an example of what im talking about). What i wanna do is make a .txt file and place all the names of the planes instead of having it in the main code.

Given that I have this two COLLECTIONS:.

1st.col

Is it possible to Two-way bind an collection in Blazor child component?

TLDR; A property of type list in an object is set to NULL when the ValueChanged EventCallBack handler is executed, and this throws NullReference exceptions because its set to null in the pages.

I have the following example:

I was playing some clash of code at codingame.com and saw somebody's code, but didn't quite understand it.

The goal is to check if there's any double characters in the string in a row. So the string "Hello" should return True, since the double "l" in a row. But the string "Mama" should return False since the characters "a" are not behind each other.

Could someone explain this code?

So I have data in text file like this:

I have this program that is connected to a phpmyadmin MySQL database. It has a combobox whose values I want to update whenever the drop-down arrow is clicked. I use the combobox's postcommand parameter to call a function that executes a query and updates the values. Here is my code simplified:

I have just looked at many examples regarding custom login page and every single example uses the same "/login" path. After so much frustration I finally got the login to work with the default.

I want the login form to be rendered at "/" and not login.

Once authenticated, I want it to go "/home".

I am assuming the POST still goes to the default "/login"?

I have tried both on the POST form "/" (Same as the path of the form with GET) & "/login"

Now when I try to login, it keeps redirecting me back to the same "/" with the form.

Here is the basic API logic again: Default login page should be at "/", Form is posted to "/login", Success Url after login is "/home", "/home" and "/mama" are protected routes. After logout, it should redirect to "/"

I cant get through the app, and not sure if anything is missing, It keeps showing the same form login as if I am not getting through even though the password is clearly okay

Here are the routes as explained in the WebConfigurerAdapter filer:

I am a beginner at Spring Boot and really struggling to get this. I am not finding Spring boot's security API very intuitive at all, but I'm trying to get it.

I am going to use MySql with JPA to get Users from the Database, But initially just to ensure that the security scaffolding works, I am just hard coding a User From Employee Details Service.

After a lot of trouble, I have managed to get the basic Authentication to work, but the Authorisation is not working. I have edited the question to reflect the basic issue:

I am aware that there are other questions out there before people mark this as duplicate, I have gone through all of them, they all respond with basic answers that I think are already working in my app.

At the end /home path is for home method, /mama path is for role mama

Here is the code:
