QUESTION
Some time ago, a Visual Studio update added a hot reload feature. It be handy, but it also can be annoying especially when you're testing and you don't want to reset the current state of the front end. Visual Studio injects the script whether you're debugging or not.
How can hot reload be disabled? My Visual Studio version is 16.10.3
...ANSWER
Answered 2021-Aug-27 at 14:23You can change this feature here:
Tools > Options > Projects and Solutions > ASP.NET Core > Auto build and refresh option
Options to automatically build and refresh the browser if the web server is running when changes are made to the project.
Your options in this dropdown are the following:
- None
- Auto build on browser request (IIS only)
- Refresh browser after build
- Auto build and refresh browser after saving changes
Also note my version of VS is 16.11.1

QUESTION
Google recently sent me an email with the following:
One or more of your web applications uses the legacy Google Sign-In JavaScript library. Please migrate your project(s) to the new Google Identity Services SDK before March 31, 2023
The project in question uses the Google Drive API alongside the now legacy authentication client.
The table on the migration page (https://developers.google.com/identity/gsi/web/guides/migration) says:
Old New Notes JavaScript libraries apis.google.com/js/platform.js accounts.google.com/gsi/client Replace old with new. apis.google.com/js/api.js accounts.google.com/gsi/client Replace old with new.I was currently using gapi
on the front-end to perform authorization which is loaded from apis.google.com/js/api.js
. According to the table I would need to replace it with the new library.
I've tried the following to authenticate and authorize in the same manner that I used to do with gapi:
...ANSWER
Answered 2021-Aug-26 at 19:19In the new Gooogle Identity Services, the authentication moment and the authorization moment are separated. This means, GIS provides different APIs for websites to call on these two different moments. You cannot combine them together in one API call (and UX flow) any more.
In the authenction moment, users just sign in or sign up into your website (by leveraging the information shared by Google). The only decision users need to make is whether they want to sign in (or sign-up). No authorization-related decison need to make at this point.
In the authentication moment, users will see consistent One Tap or button UX across all websites (since the same scopes are requested implicitly). Consistence leads to more smoothly UX, which may further lead to more usage. With the consitent and optimized authentication UX (across all websites), users will have a better experience with federated sign-in.
After users sign-in, when you really want to load some data from a Google data service, you can call GIS authorization API to trigger an UX flow to allow end users to grant the permission. That's the authorization moment.
Currently (August 2021), only authentication API has been published. If your website only cares about authentication, you can migrate to GIS now. If you also need the authorization API, you have to wait for further notice.
QUESTION
In d3
, we may change the order of elements in a selection, for example by using raise
.
Yet, when we rebind the data and use join
, this order is discarded.
This does not happen when we use "the old way" of binding data, using enter
and merge
.
See following fiddle where you can click a circle (for example the blue one) to bring it to front. When you click "redraw", the circles go back to their original z-ordering when using join
, but not when using enter
and merge
.
Can I achive that the circles keep their z-ordering and still use join
?
ANSWER
Answered 2022-Feb-18 at 23:13join
does an implicit order
after merging the enter- and update-selection, see https://github.com/d3/d3-selection/blob/91245ee124ec4dd491e498ecbdc9679d75332b49/src/selection/join.js#L14.
The selection order after the data binding in your example is still red, blue, green even if the document order is changed. So the circles are reordered to the original order using join
.
You can get around that by changing the data binding reflecting the change in the document order. I did that here, by moving the datum of the clicked circle to the end of the data array.

ANSWER
Answered 2022-Jan-10 at 08:29I used yield
and re.finditer
.
The yield expression is used when defining a generator function or an asynchronous generator function and thus can only be used in the body of a function definition. Using a yield expression in a function’s body causes that function to be a generator function
Return an iterator yielding match objects over all non-overlapping matches for the RE pattern in string. The string is scanned left-to-right, and matches are returned in the order found. Empty matches are included in the result.
If there are no groups, return a list of strings matching the whole pattern. If there is exactly one group, return a list of strings matching that group. If multiple groups are present, return a list of tuples of strings matching the groups. Non-capturing groups do not affect the form of the result.
The regular expression ([^\r\n]*)(\r\n|\r|\n)?
can be divided into two parts to match (that is, two groups). The first group matches the data without \r
and \n
, and the second group matches \r
, \n
or \r\n
.
QUESTION
I found out that in C++ we can use +
in lambda function +[]{}
Example from the article:
ANSWER
Answered 2021-Dec-28 at 10:21It's not a feature of lambda and more is a feature of implicit type conversion.
What happens there is stemming from the fact that a captureless lambda can be implicitly converted to a pointer to function with same signature as lambda's operator()
. +[]{}
is an expression where unary +
is a no-op , so the only legal result of expression is a pointer to function.
In result auto funcPtr
would be a pointer to a function, not an instance of an object with anonymous type returned by lambda expression. Not much of advantage in provided code, but it can be important in type-agnostic code, e.g. where some kind of decltype
expression is used. E.g.
QUESTION
I have a simple chat app using Firebase v9, with these components from parent to child in this hierarchical order: ChatSection
, Chat
, ChatLine
, EditMessage
.
I have a custom hook named useChatService
holding the list of messages
in state, the hook is called in ChatSection
, the hook returns the messages
and I pass them from ChatSection
in a prop to Chat
, then I loop through messages
and create a ChatLine
component for every message.
I can click the Edit
button in front of each message, it shows the EditMessage
component so I can edit the text, then when I press "Enter", the function updateMessage
gets executed and updates the message in the db, but then every single ChatLine
gets rerendered again, which is a problem as the list gets bigger.
EDIT 2: I've completed the code to make a working example with Firebase v9 so you can visualize the rerenders I'm talking about after every (add, edit or delete) of a message. I'm using ReactDevTools Profiler to track rerenders.

ANSWER
Answered 2021-Dec-13 at 23:35This is what I think, You are passing Messages
in ChatSection
and that means that when Messages
get updated ChatSection
will rerender and all its children will rerender too.
So here is my idea remove Messages
from ChatSection
and only add it in Chat
.
You already using useChatService
in Chat so adding Messages
there should be better.
Try this and gets back too us if it working.
If still not as you like it to be there is also other way we could fix it.
But you have to create a working example for us so we could have a look and make small changes.
