jigsaw | Jigsaw七巧板 provides a set of web components | Frontend Framework library

I'm receiving a very strange response from this code. My idea was:

1. To create 8 html elements mapping an array.
2. Selecting the #cart-button id to attach an eventlistener (click) and passing to it the id of the of the html element (I'm trying to obtain these values from the key attribute).

Sometimes in the console I'm obtaining all the results OK (1 clicked, 2, clicked...), but sometimes the result is null clicked.

I'm trying to understand why this is happening. Thank you very much!

In a model with an embedding layer and SimpleRNN layer, I would like to compute the partial derivative dh_t/dh_0 for each step t.

The structure of my model, including imports and data preprocessing.

I have a PHP page. In the header I have added a style sheet (style.css) like this:

I am using useEffect to get the total jigsaw pieces from my async storage to be displayed on the home page. I use async storage to get the number of jigsaws stored in the storage then for each jigsaw, i add the total amount of jigsaw pieces. I do this within useEffect as the total amount of jigsaw pieces may change depending on if the user adds more jigsaw to their collection. However, when i use useEffect, my total amount of jigsaw pieces constantly updates and never stops.

Code:

I have a code (not originally written by me) and, while trying to update it, I'm getting this error:

I'm trying to categorize the type of jigsaw puzzle pieces (number of heads, if it is a border or a corner...) by analyzing their contours.

The approach I'm trying to follow is analyzing this type of plot (from this paper) that "unwinds" the cartesian coordinates of the contours of the puzzle piece by converting it to polar coordinates; however I'm not able to replicate it.

I've tried with:

We're migrating from Java 8 to Java 11.
We have a legacy project Y which depends on another legacy project X.
The project X has no sources, it's just a collection of about 300 jars.
The build is ant-based, no maven.

I cannot build the project Y now with JDK 11 (neither in Eclipse, nor externally)
because it says "The package org.w3c.dom is accessible from more than one module: , java.xml"

I get this error in Eclipse on a line which does import org.w3c.dom.Document;

When I do an external build (with ant, outside of Eclipse) I can build successfully (with basically the same build.xml as under JDK 8)?! How come only Eclipse is complaining?! Is it because of this javac bug which I reference below.

I was reading here (these are directly related to my issues):

https://stackoverflow.com/a/53824670/2300597
The package org.w3c.dom is accessible from more than one module: , java.xml
http://mail.openjdk.java.net/pipermail/jigsaw-dev/2018-December/014077.html

but I am still unable to fix these build issues.
I tried 7-8 different things but nothing helps.

I think the clash is between org.w3c.dom package from some of these 300 jars and the same package in the JDK module java.xml.

The weird thing is that org.w3c.dom.Document doesn't seem to be present in any of these 300 jars, it's just that other classes from the same package are present in jars.

I am deadlocked, I see no way to fix this.
I cannot lightly change project X because it's a shared library used by multiple legacy projects.
On the other hand, I cannot remove java.xml module from the build path of project Y.
So I don't know how to approach this.

Isn't there some way to just say: OK, use the classes from the JDK first, then use those from the JARs (even though they share the same package, they are not the same class).

What is the right way to fix these errors?

I'm in the process of upgrading a small spring boot application from Java 8 to Java 11. This project uses the package javax.smartcardio. I'm building it with maven.

The pom.xml basically contains the following dependencies/plugins:

• spring-boot-starter-parent (2.5.6)
• spring-boot-starter-test
• spring-boot-starter-web
• spring-boot-autoconfigure
• pebble-spring-boot-2-starter
• spring-boot-starter-security
• spring-boot-maven-plugin
• maven-resources-plugin
• maven-assembly-plugin
• exec-maven-plugin

After upgrading all my dependencies and using OpenJDK11 the project compiles and runs fine (mvn clean package). Especially the parts using the classes from javax.smartcardio also work fine.

Intellij however, is highlighting all my imports of the package javax.smartcardio. in red. When hovering over it, it tells me Intellij - Package 'javax.smartcardio' is declared in module 'java.smartcardio', which is not in the module graph. Intellij suggests to add this module via compiler options with --add-modules java.smartcardio. When doing so, Intellij stops highlighting the imports.

My question is now, why does Intellij highlight those imports, even though everything is compiling and running just fine nevertheless? What am I missing? Is it important to add that module when compiling? Maybe maven does something in that regard for me already? If so, which part should I lookout for?

I've read about using module-info.java, but came to the conclusion that using it to resolve my problem would not be the best solution. See also Any plans for Java 9 Jigsaw (module) of Spring projects?

The text lined up before I added the the the links to them and now they do not. Any help is much apreciated. I will post my css and html below. I will also provide a screen shot of the specifec problem. Not exactly sure what cause the shift. Everything is broken down into classes and the footer class is at the bottom of the HTML.
