machineid | unique machine id of any host ( without admin privileges

Having spent some time searching for an answer, and in the process learning more about how dyanamoDB works, I now have a solution which works.

Essential I needed to convert the attribute key-value pair from the query into a document.

Achieved using:

This can be addressed by typing the return as nullable so that you do not get a returned error and then applying a default value for the int. Alternatively, you can just assign it to a nullable int. Note, the assumption here of an integer return type of the ID. The same principal would apply to a Guid as well.

You could add console.log(Machines) to check the response in Console panel. Then you will find the property name in response is camel case.

Change your code below:

I think here is possible aggregate min and max datetimes per groups, then pivoting by DataFrame.pivot_table with aggregate function like mean, sum and last join together:

The bug was reported and fixed here in library repository: https://github.com/reactiveui/ReactiveUI/issues/3091

If you are using React-router@v5, you can write your route as follow:

When you use a child_added event listener, your callback will be invoked whenever one of the children under that database location changes. Using this, you would need to store high_temp_coil and low_temp_coil in variables outside of the function so that you can compare them properly. Because you store the result in an element, you could pull the current values from there.

Note: In the below snippets I follow the convention of naming the DataSnapshot object as snapshot, reserving data for the plain JavaScript object returned by snapshot.val(). This aids in preventing confusion later on, especially when not using TypeScript.

This will work:

When you run program.textContent = "Program"; you're actually removing the span from the page (you can see that in the browser's dev tools).

What you can do instead is program.insertAdjacentText('afterbegin', 'Program')
