SCUTTLE | Utility Transport Taxi for Level Environments | Robotics library

I've written some code for a simple popup feature for a website and have managed to make it work as long as I'm individually specifying the array index of each popup box, however this requires me to manually duplicating the code for each array index. See below:

From what I have read, core Gnome development began with C and this was extended by Vala (2006) and Genie (2008). Vala syntax appears to have been aimed at the Java/C# syntax/developer, whereas Genie appears to be aimed at Python (and a handful of others).

There are also certain developers who appear to be attempting to scuttle these two great development tools - by pushing for a move to, for lack of a better term, non-native technologies like Javascript and Rust - requiring additional virtual machines or runtime binaries.

Yet there appears to be a resurgence in Vala primarily driven by the applications developers. This is clear from the rise in activity on the Vala compiler and the proposed activities of the 2018 Outreach Program where Vala is a core feature.

So this brings us to the technical relationship to Genie. From my reading, Genie only depends upon GLib whereas Vala depends upon the Gnome desktop environment. Is this relationship correct? Secondly, is Genie built into the Vala compiler valac or is it separate? From a compilation perspective, are they integrated technologies?

I am testing how to change text and CSS elements using Javascript

I have three buttons in my HTML, only one so far that I am using (Change Title). I would like to change the H1 Text when I click the button.

Using my current coding, when I click the button nothing happens and I get the following displayed in the web developer tools console:

*ReferenceError: changeTitle is not defined [Learn More] Index.html:1:1

Onclick file:///D:/Google%20Drive/Programming/EDX/Introduction%20to%20JavaScript/Module_1/index.html:1:1*

Questions:

1. Can someone please help me understand why the browser says that the changeTitle function is not defined when I believe I have defined it in the external JS file.
2. Am I able to use the onclick method?? in the tag element so that I do not have to use buttons?

Please find snippet below:

I am trying to translate SQL into Rails query with this site but it says:

Scuttle parser error, check your SQL syntax.

I am sorry but I don't really know how to write SQL request... so I've no idea where I am wrong... Btw if anyone knows how to write this as a rails query I'd be very happy

I am working on a Meteor App, using the Node.js package called "js_xlsx" from "SheetJS", made by "SheetJSDev". I am using this package to transform an uploaded Excel sheet into JSON in the back-end, so I can store it in my MongoDB and use it to do some fancy classified stuff in the front-end. There's just one problem. The package skips columns that have an empty header, except for the right-most column with an empty header. I already figured out that the package processes columns with an empty header just fine, but because JSON keys need to be unique, it only saves the last column with an empty header in the JSON object.

Examples:

With all headers filled:

As you can see, all works well when all headers are filled.

With the first and 2nd last header empty:

Here you see that the 2nd last column gets put in the front, with an "undefined" header and the first column is not even in there (because it gets overwritten by the 2nd last column, because they both have "undefined" as their keys).

With the first 3 columns and the 2nd last header empty:

Same stuff as with the 3rd and 4th image. Only the last column with empty header will make it into the JSON object.

Now, I have scuttled through the sourcecode and searched the GitHub page and even asked Google to help me out, without much avail.

What I want to know is:

How do you make js_xlsx process all columns with empty headers?

The link to the GitHub page for the package is:

Any help is much appreciated!
