man system is your friend here. This is what is says on my system:

The system() library function uses fork(2) to create a child process that executes the shell command specified in command using execl(3) as follows:

You seem to be confusing useState with the class component's state.

Running setState({ testInfo: testInfoArray }); sets the entire state to { testInfo: testInfoArray }, removing state.selectedParagraph entirely, causing it to be undefined.

You'll want to use useState multiple times, like this:

Looking at error TypeError: Cannot read property 'latitude' of undefined. My guess is value of device.deviceData is undefined.

So,Please do verify with console.log(device) if deviceData field exists in device.

And, to fix above issue you can try

Starting with 6.4 RC5 (which is the version you run as of this writing and should provide this in your original post):

The collection of thymeleaf user interface template pages are no longer found in the context root of the web application resources. Instead, they are organized and grouped into logical folders for each feature category. For example, the pages that deal with login or logout functionality can now be found inside login or logout directories. The page names themselves remain unchecked. You should always cross-check the template locations with the CAS WAR Overlay and use the tooling provided by the build to locate or fetch the templates from the CAS web application context.

Please read the release notes and adjust your setup.

All templates are listed here: https://apereo.github.io/cas/development/ux/User-Interface-Customization-Views.html#templates

Fix composer.json

I have created an issue on the PHP package: https://github.com/pusher/pusher-http-php/issues/295

It is true this version is broken, but the fix should be in the composer.json file. Mine looked like this:

If this isn't going to throw an exception then I don't know what is going to.

This is caused by using blocking code within Netty's event loop.

The code over here is making a blocking request 20 times in a row which cause the machine to break. I don't know what data is coming from the client but I would never recommend to do it in this manner.

When you're stuck on a problem, it never hurts to go back and consult the documentation.

You'll find information like this:

A border layout lays out a container, arranging and resizing its components to fit in five regions: north, south, east, west, and center. Each region may contain no more than one component, and is identified by a corresponding constant: NORTH, SOUTH, EAST, WEST, and CENTER. When adding a component to a container with a border layout, use one of these five constants...

When you add your button, you do this:

According to the Go memory model:

https://golang.org/ref/mem

There are no guarantees that one goroutine will see the operations performed by another goroutine unless there is an explicit synchronization between the two using channels, mutex. etc.

In your example: the fact that a goroutines sees done=true does not imply it will see a set. This is only guaranteed if there is explicit synchronization between the goroutines.

The sync.Once probably offers such synchronization, so that's why you have not observed this behavior. There is still a memory race, and on a different platform with a different implementation of sync.Once, things may change.
