Grider | Secure client for OpenSim 's Hypergrid using LibOMV | Menu library

A bit stuck on this one. Taking a Grider course on Docker through Udemy.com.

I just keep getting the following error when I do:

I just finished most of the tutorials of an online class on Udemy by instructors named Colt Steele / Steven Grider and facing a project confusion. I am on a project where I was introduced to making a "debounce" function to not exexcute an api call eveytime I input a key inside the input bar. However, I am not understanding the logic behind the debounce function(for example, the spread (...args) right after the return and overall the "shield" it offers. I am wondering if someone can help explain this in a clearer manner? Thank you!

I am following full-stack react course by stephen grider. Everything looks good but after google social auth, I can't see new users collection getting added to the mLab database.

I am using passport.js and mongoose.js.

Here is the relevant source code:

index.js

I just purchased a course of React Native from Udemy, Stephen Grider is the author of the course. So basically I'm typing my code with him as he types. But unfortunately I'm stuck in a error in the signup process of track application. Whenever I click on Sign Up button after putting email and password so my screen shows this error. Please check my code if there is any mistake so please let me know.

Error

signup is not a function. (In signup({ email: email, password: password })', 'signup' is undefined);

SignupScreen.js

This is my first try at a simple React application. Working with the Openweather API and AXIOS. I took Stephen Grider's course on Udemy and I'm trying to create something on my own now, but I still have problems when passing data between components. I have a SearchBar component and I'd love to be able to pass the input value to the parent component's state, so I can then update it with each search and render it into the DOM. However, I keep running into errors. I tried passing a function as a prop to my SearchBar component but I'm getting errors:

setState(...): Can only update a mounted or mounting component. This usually means you called setState() on an unmounted component. This is a no-op. Please check the code for the App component.

citySearch is not defined

This is confusing to me, as I tried to copy the exact steps from the course, where it seems to be working just fine. But again, I'm very new to this so it is probably just me making some sort of a rookie mistake. Any tips would be much appreciated.

Check my code below:

I would like to learn Server side rendering and while searching in google,i've seen many topics about a framwork called nextjs,and after trying it,i found it pretty good.SO now i would take a serious course on SSR,but after a search on Udemy I've found a course which is rated 4.7/5 of Stephen Grider,but in the course content i've not seen next.js.Here is the course link : Server Side Rendering with React and Redux.

I don't have much experience with SSR,but it seems that there are two ways to make it:With React,redux,node/express or Next.js. When i've tried next.js,i've not used react-router but in the description of the courses of udemy,the instructor talks about using react router. I really need your advices before i learn it seriously,and i need to know the best solution between the 2 approches.

I wonder why my state todos named todo not todos in the redux dev tools .. From where that name came ? There is no initial state .. i wonder..

I'm following Stephen Grider udemy course but with todos instead of streams as a revision

why i have to return it by state.todo not state.todos??

I've been learning Solidity using this course by Stephen Grider and it's been going well until now, where I am trying to deploy my code to the Rinkeby test network.

For reference, I am using Node version 11.15.0 with npm version 6.7.0 with these dependencies:

web3.eth.getAccounts() is not working for me. The code below shows "error" on execution (gets rejected). I am using web3 1.0.0 beta-46. I am learning from Stephen Grider's tutorial videos and he used beta-26, is it version related issue or am i doing something wrong?
