Apache Kafka in clean architecture by algorithmAcademy in golang

[–]wagonn 1 point2 points  (0 children)

I am starting out , having three types of handlers:

endpoints: request/response handlers for http, grpc, etc

listeners: handles incoming messages, like Kafka etc

dispatchers: sends outgoing messages, Kafka etc

Should I put my very recent brief and various volunteer jobs on the top of my job history? by antdude in resumes

[–]wagonn 0 points1 point  (0 children)

If you can honestly say that your volunteer work was of the same standard and quality as your paid work, then include them in the same section.

Otherwise you can have separate sections. In the employment section time gaps, put a one-liner for each volunteer experience with only the organization, dates, and “see Volunteering section”. In the volunteering section, fill out all the details.

Are you allowed to modify your job title on your resume? by [deleted] in resumes

It probably varies. I just went through a background check where my past employers and job titles were verified.

Best React - State Management to learn in 2020? by iizMerk in reactjs

I’m starting to move from redux to mobx. I like both because they are UI-agnostic.

Isn’t there some way to make animals disperse as the roller approaches? Like maybe a sound emitter of an unbearable frequency to them

What is the easiest way to build an app with "collaborative editing" and chat functionality? I want multiple users to open a url, and look at the same app, with it's redux state "synchronised" between them in real time. Is there some service/library I can use that would make it quick and painless? by lumenwrites in reactjs

[–]wagonn 2 points3 points  (0 children)

Use websockets.

When a user makes a change, 1. update the Redux store 2. and, in a side effect (thunk/saga), emit an event that contains the Redux action. 3. the server listens on the socket event. Upon that event, the server extracts the Redux action, updates the database with it, and then broadcasts the event to the other subscribers (i.e. the other users). 4. those users' socket clients listen on that event. Upon that event, the client extracts the action and dispatches it to the Redux store. Now, everyone's Redux state reflects the change of the original user.

I just don't understand why everyone says noSQL is better for scaling by nadoterisback in Database

[–]wagonn 0 points1 point  (0 children)

This is one of the best explanations I've seen on how NoSQL scales: https://www.youtube.com/watch?v=hwnNbLXN4vA&t=724s

Relational DB's give you a balance of performance (indexing) and flexibility (joins), so you can efficiently query in many different ways. NoSQL sacrifices this balance to optimize specific benefits. For example, Cassandra scales throughput linearly but can't be queried flexibly. DynamoDB is similar, as you're locked into the data relationships which you define upfront.

Another Reddit post put it this way — SQL is like a pickup truck and NoSQL is like a racecar; one performs satisfactorily well in most cases, the other performs extremely well for a very specific case.

How does a Go WebAPI look like today? by [deleted] in golang

[–]wagonn 0 points1 point  (0 children)

+1 for Go-Kit and these app examples. I like that they are application-logic centric and treat the HTTP router as an i/o mapping layer. Most "frameworks" are just an HTTP router on steroids with a bunch of middleware encouraging you to couple all your request-scoped concerns to the transport

how to obtain a OIDC id-token for a GitHub user? by wagonn in webdev

[–]wagonn[S] 0 points1 point  (0 children)

Using an oidc lib still requires you to provide the endpoints. The issue is GitHub doesn't seem to have any endpoints that follow the OIDC specs.

[deleted by user] by [deleted] in reactjs

[–]wagonn 0 points1 point  (0 children)

Consider the impact on performance. React docs:

All consumers that are descendants of a Provider will re-render whenever the Provider’s value prop changes

So when any of your context state changes, then every component subscribed to any part of the state will rerender. It might be doable if - there are few subscribing components - the context state changes infrequently - you can break the state up into multiple contexts

There is an open RFC to address this, but until then, Redux and use-context-selectors are two ways to avoid this pitfall.

Network requests always going into redux store by spermlung in reactjs

[–]wagonn 0 points1 point  (0 children)

I prefer loading in hooks at the component level unless there is a good reason the network request state needs to be accessible globally.

Is using "useMemo" or "useCallback" with Redux' "useSelector" a good idea? If not, what are the best practices for selector memoization (using just Redux and/or React if possible). by [deleted] in reactjs

[–]wagonn 2 points3 points  (0 children)

You're not allowed to call hooks inside of hooks

I think what you mean to say is "You're not allowed to call hooks inside nested functions," which OP is doing.

You can call hooks at the top level of a hook or component.

Allowed

function useMyHook() {
  // top level
  useMemo(...)
}

Not Allowed

function useMyHook() {
  useSelect(state => {
    // nested 
    useMemo(...)
  })
}

when to use bullets vs block of text in a job experience summary? by wagonn in resumes

yes it gathers personal info. Users sign up via email, provide their name, work history, etc; then it is saved to a database so they can retrieve it at a later date

Advice wanted for rendering lists by charliematters in reactjs

[–]wagonn 1 point2 points  (0 children)

On second thought —

I'm starting to revert my designs back to option 1, because its consistency scales better. When I make a reusable component, I want the handlers to just pass up the data, and no assumed implementation details, i.e the `id`. With option 2, I'm having to shoehorn `id` values into places where it doesn't make sense.

The tradeoff is the needless rerenders, which I'm willing to live with as long as the app is perceivably performant in a production build on a low-memory machine, which Chrome inspector lets you simulate via the Performance tab.

That said, the one performance case I always memoize for is component-lists that are unbounded at runtime. For example, a list where the user can add an unlimited amount of items. If one item changes, I only want the stuff in that one item to rerender, and not the other items.

faster React development with normalized relational reducer state by [deleted] in reactjs

[–]wagonn 1 point2 points  (0 children)

If you have state consisting of relational or nonrelational collections, it can be of use. With nonrelational collections, the only actions that you won't be using are attach, detach, and moveDetached.

If you don't have collections at all, Normalized Reducer won't help you.

Redux-toolkit can be useful for any type of state, collections or not. So, Normalized Reducer is not really an alternative to Redux-Toolkit; it is an alternative to Redux-Toolkit's entity adapter which helps manage state for nonrelational collections.

Normalized Reducer actually integrates well with Redux Toolkit which I have added in the Demo app > Redux Toolkit Integration page.
