QUESTION
One thing which I have learnt from working with Identity Server is that, out of the box, ASP.NET Core Identity does not play too well with Identity Server. Refer to this question.
ASP.NET Identity contains a way of ejecting users where a particular user's data has changed. This is regulated by the SecurityStamp column of the aspnetuser table. When the stamp changes, the next time the cookie is validated, it fails validation.
This is turned on by default and it is the reason why it does not work well with Identity Server.
You end up with users getting kicked out erratically. And when you expect it to kick users out, it doesn't.
Anyhow, how do you disable this feature of ASP.NET Identity???
There is a column on the UserManager called SupportsUserSecurityStamp.
However, it is a "getter" only and I cannot find any configuration setting for switching that to return false.
It seems to me that the only way is to derive from the UserManager class and make that property only ever return false.
That feels like a hack. Especially when you look at the code for that property on Github:
...ANSWER
Answered 2021-Jun-14 at 00:24I turned the SecurityStamp feature off, as described in the question.
So, I created a class which inherits from the UserManager class.
Should look something like this:

In row 2, I have a value "AVE" in the 'address' column that I would like to join with the 'address' value in row 1. The result should be row 1 'address' reads as "NEWPORT AVE / HIGHLAND AVE". How do I do this?
I also need to perform the same function with row 3 where 'action_taken' reads as "SERVICE RENDERED" with "RENDERED" taken from row 4.

QUESTION
I have been trying to build my Java web application using gradle. Everything work fine in the local drive and the build goes through as expected. However, when I switch to using the clearcase MVFS File system (G:), the build seems to behave erratically. From the windows 10 command line, if I change directory to the G:\ drive location, and execute "gradle war", it works fine the first time. After that, I run the same command again - the already created war file gets deleted and the classes are removed. It's bizarre. I did the following and still the behavior is the same.
- disabled daemon
- disabled file watching
Its the same behavior with Gradle 7 and gradle 6.8.
When I delete the .gradle folder, everything works fine again.
So - Does gradle not support the NFS and MVFS File System ? What is the solution to this problem ? Any help is appreciated.
...ANSWER
Answered 2021-May-11 at 06:44Does gradle not support the NFS and MVFS File System ?
That is why I proposed in 2018 to use gradle only in snapshot views.
Especially considering a "gradle --no-daemon build" does defeat the purpose of having the daemon at all.
A build is better served in a local filesystem than a mounted one (MVFS dynamic views) which relies on where your view server is.
QUESTION
I am having problems with making a simple systemIcon flash in SwiftUI. I got the animation working, but it has a silly behaviour if the layout of a LazyGridView changes or adapts. Below is a video of its erroneous behaviour. The flashing bell stays in place but when the layout rearranges the bell starts transitioning in from the bottom of the parent view thats not there anymore.
Has someone got a suggestion how to get around this?
Here is a working example which is similar to my problem
...ANSWER
Answered 2021-Apr-21 at 16:07Looks like the animation is basing itself off of the original size of the view. In order to trick it into recognizing the new view size, I used .id(UUID()) on the outside of the grid. In a real world application, you'd probably want to be careful to store this ID somewhere and only refresh it when needed -- not on every re-render like I'm doing:
QUESTION
As per the requirement, I have to log out the user when he closes the last tab on a browser.
...ANSWER
Answered 2021-Mar-19 at 12:59The only sure way to implement this that I can think of is using websockets and the concept of keep-alive. Or a manual periodic poke to the server to reset a timer that would logout the user if the timer runs out.
You can't trust the browser in a cross-platform way to allow you to fire an event when the browser closes or that the user loses electric power.

...ANSWER
Answered 2021-Mar-16 at 18:49You forgot to import FormsModule in app.module. By the way are you sure you understand custom controlValueAccessors as you seemed to have used ngDefaultControl. I would suggest you to read why controlValue accessors are needed. Also template type checking has nothing to do with change detection(Its just for type checking your html bindings.)

QUESTION
I've been working on developing a UI-component that always points to the next checkpoint as the user plays through the game. My issue is that I don't know how to update the rotation of the arrow in relation to the player and the next checkpoint. With my current setup, the arrow rotates erratically, or spins in circles. I believe the nodes I want to use are the "Find Look at Rotation", "RInterp To", and "Add Rotation."
Here's what I have so far: https://imgur.com/a/130u4k6
My player actor is a pawn, the checkpoint is an empty actor class that I have hidden when the game is being played, and the waypoint arrow is a static mesh floating outside the playable environment that I setup a 2DCaptureComponent and green screen, such that I can update the rotations of the waypoint arrow during the game, and the UI will automatically update.
-- Update --
I was able to set the initial rotation of the waypoint arrow correctly using this setup: https://imgur.com/a/VFPx7tx
I changed the "Add Rotation" node to "Set World Rotation", and added -90 to the Yaw (to offset the initial orientation of the waypoint arrow). However, after setting the initial rotation, it no longer updates the rotation after the player actor rotates. Any insights?
-- Edit --
Here is the rotation angles of 1) the waypoint arrow in the blueprint capture class, and 2) the rotation of the blueprint instance as it exists in the world: https://imgur.com/a/CB60aq4
...ANSWER
Answered 2021-Mar-04 at 21:44Use Set World Rotation instead of Add World Rotation.
You should use Get Player Pawn then Get Actor Location. And for rotation, I think you can do Get Player Camera Manager then Get Actor Rotation if you want the camera's rotation. Or, if you want the pawn's rotation, you should use Get Player Pawn then Get Actor Rotation.
And to handle the offset you need, implement your arrow as an actor, with the mesh as a Static Mesh Component which is a child of the root. You can apply the offset you need specifically to the mesh, so that it points in the direction of the actor's local forward.

QUESTION
I have a container with dynamic content a user can interact with. It could be a YouTube video (iframe), amongst other things.
A user can drag and drop an image into this container and it'll replace the dynamic content with their image.
I'm aware that due to the dynamic content, drag events will behave erratically in the container, so I need to do pointer-events: none.
The HTML container has the following classes ant-upload-drag and ant-upload-drag-hover. The ant-upload-drag-hover class is only active when the image being dragged is on-top of the container.
I have CSS akin to the following where ant-upload-drag-container contains the dynamic content that I want unreachable by pointer-events:
ANSWER
Answered 2021-Feb-27 at 17:07I'm not sure whether pointer-events: none interferes with the drag-and-drop events but it would explain your bug.
I'd suggest that you instead put a layer on top of the container that catches these events instead.
Here an example with a button and the layer is toggles (by a class) every 3 seconds.
QUESTION
I have a water monitoring web-page that shows which sprinklers in a list are running, and the amount of remaining time left until they stop/turn off.
I am using an array as a simple state machine to remember data received via web socket from server-side nodejs code. I've got Vue.js on the client-side to reactively watch the list array for changes and update the page.
For simplicity, the arrays looks something like this:
...ANSWER
Answered 2021-Feb-25 at 23:40I'll give you a few options. First, I'll answer your original question. Second, I'll give you a suggestion that will make it more performant. Third, I'll offer another option that changes how you store your state.
Option 1I believe the main issue is that as you iterate over the source array you need to find the matching elements in the state machine array. There are many methods to doing that but the easiest is to simply "do it". Meaning as you find an element to compare, then find the matching element in the other array. Since you have nested data, you'll do that at two levels.
This code will work (but is not performant):
