kandi X-RAY | wither Summary
An ODM for MongoDB built on the official MongoDB Rust driver. Please on github!. The primary goal of this project is to provide a simple, sane & predictable interface into MongoDB based on data models. If at any point this system might get in your way, you have direct access to the underlying driver. This project is tested against MongoDB 3.6, 4.0, 4.2 & 4.4.

QUESTION
I am trying to make a chat application with scaledrone. I was following this tutorial: https://www.scaledrone.com/blog/javascript-chat-room-tutorial/ but after setting up the basic chat, I wanted to let users define their own name. So I made an input box and then tried using js to take the input box value and assign it to a variable. And then for the name part of the chat application, instead of using the random name function I was using earlier. However, I got the error "can not read properties of null(reading addEventListener) in my console and the submit button did not show up at all. What did I do wrong? The code I used is in pastebin links below. The scaledrone documentation is here: https://www.scaledrone.com/docs/api-clients/javascript Thanks in advance. also, I added the raw text of my javascript file below because stack overflow won't let me post without adding some code(first time posting to stack overflow lol).

QUESTION
I have following code.
I'm trying to store a value in my state and every time the user goes to the previous step he can see what he has selected and after that he can change and move on to the next step.
At the first step, everything works good. For example, the user selects the second text and proceeds to the next step, and when he returns to this step, he sees that the second text has already been selected...
The problem is with the second step, I write all the same, but it doesn't work for the second step.
The error says onSelect is not a function in src/component/SelectCard.js. Please help me solve this problem.
Here is my code.

I finished up my first GUI project that allows the user to open any PDF file by wither typing a product key, or manually find it using a tree view. I have all the files in the same folder as the application, the problem is that when I used pyinstaller to make it an .exe it wont pull up. and anytime I move it nothing pulls up because the code is linked to that specific location. my question is how do you write it to where the filepath is linked to a specific folder, and even if said folder moves, it still accesses those files?

QUESTION
From what I've seen here if I have an Azure App Config set up and want to have a feature flag in it, in order to read its value or take advantage of it I must:
- Install a nuget, separate from the Microsoft.Extensions.Configuration one I already need for App Config
- Add "UseFeatureFlags" in "CreateHostBuilder"
- Register the feature management in startup services
- Have an enum, designed specifically for each flag
- Register the feature manager in the "_ViewImports"
And I don't see what benefit ALL THAT gives me over having a standard config value with wither "true" or "false" and skip all the previous steps and just go "if (featureValue)".
So, what is the benefit I am not aware of that is worth going through all that trouble?
...ANSWER
Answered 2021-Oct-06 at 14:48In short here are some of the pros:
- a centralized location to manage feature flags
- labeling options
- feature filters
A Targeting filter is a built-in filter which allows dynamic enabling or disabling of features for specific users or groups. For example, you can use a targeting filter to enable a feature for only a specific user during a demo. You could also use it to progressively roll out new features to users in custom groups or "rings", or to set a default rollout percentage to release features to all users.
Next to this, feature management helps developers address the following problems:
- Code branch management: Use feature flags to wrap new application functionality currently under development. Such functionality is "hidden" by default. You can safely ship the feature, even though it's unfinished, and it will stay dormant in production. Using this approach, called dark deployment, you can release all your code at the end of each development cycle. You no longer need to maintain code branches across multiple development cycles because a given feature requires more than one cycle to complete.
- Test in production: Use feature flags to grant early access to new functionality in production. For example, you can limit access to team members or to internal beta testers. These users will experience the full-fidelity production experience instead of a simulated or partial experience in a test environment.
- Flighting: Use feature flags to incrementally roll out new functionality to end users. You can target a small percentage of your user population first and increase that percentage gradually over time.
- Instant kill switch: Feature flags provide an inherent safety net for releasing new functionality. You can turn application features on and off without redeploying any code. If necessary, you can quickly disable a feature without rebuilding and redeploying your application.
- Selective activation: Use feature flags to segment your users and deliver a specific set of features to each group. You may have a feature that works only on a certain web browser. You can define a feature flag so that only users of that browser can see and use the feature. With this approach, you can easily expand the supported browser list later without having to make any code changes.

I created a reactive website with columns, but for some reason the columns are reaching too far on mobile screens, going too far to the left beyond where the header and footer end. I did I media query to make the two columns of the site reactive (stack on one another) and am not sure why they are stretching out like this when the screen is smaller. Can anyone fix my code so that the containers do not overflow? Thank you so much!
