nucleus | versatile update server for all your Electron apps | Dektop Application library

I m reading a book about spring 5 certifications.

I have read the following sentence The Spring Framework IoC component is the nucleus of the framework. It uses dependency injection to assemble Spring-provided (also called infrastructure components) and development-provided components to rapidly wrap up an application.

I believe that development-provided components are my annotated java classes that will be injected using DI for example a @Controller or a @Repository.

However I m curious about the second part: Infrastructure Components. what are these. where they are being injected ? can I consider the AuthenticationManagerBuilder an Infrastructure Component or are they referencing to another thing?

Thanks

I got data from Wikipedia dump like below:

I am trying to build the Zxing android app (not the libraries) using the instructions here. I was able to build the jars but cannot build the app itself. When I run mvn package android:apk I get the following error:

I got a list that contains 9 data frames and each data frame contains the following lines:

I am having a hard time adding individual data points on my barplots using ggbarplot. I seem to have an issue particularly on multi-grouped data (using fill or color). I've tried a couple different ways to add dots, but they've either resulted in an error (adding jitter) or the dots are not properly aligned to the correct bar (adding dotplot). Any help would be greatly appreciated.

Example data:

I'm trying out some Java EE and I can get my code to run on Glassfish 5.0.1 no problem. I want to run it on Payara but I can only get Payara Micro to work, the full and web-profile both crash and give the following errors that I cant find any info about. The closest related problem I could find told me to try changing my path to Java 8 instead, but that had no effect. Thanks!

I am attempting to recreate a Flash website using Three.JS but have run into a snag attempting to create some of the functionality.

What should be happening is that I want to have some button images orbit around the center of the screen. They should be able to be stopped if the mouse hovers over them and then clicked to open up a different location on the website.

I have everything working up until the requirement that the buttons stop when the mouse is hovering over them. I am attempting to implement this using a raycast, however when I am moving the mouse around the scene it seems as though the mesh is not at the same place as the rendered texture. In fact it almost seems like the mesh and the rendered image are orbiting in the opposite direction from each other.

Here is my code and I will link you to a page on my website where I am testing this revamp at so you can get a real-world example:

I have some issues trying to plot multiple boxplots in single figure using ggplot, even though I can easily do that in vanilla R. I tried to google for answers for quite a few hours, but I couldn't find anyone who had same problem as me.

So basically, I have a data frame with 25 columns

In a SLURM cluster I am submitting a shell script that calls a python script (both scripts can be found below. When the shell script executes it get until where the python script is called but then nothing happens: there is no output, no error message and the SLURM job keeps running.

I assume the entire contents of the python script are not relevant (but I included it anyway for completion). For debugging purposes I inserted the print("script started") line at the very beginning to see if it gets run but it doesn't. The last thing I see in the output is moved to directory.

I tried calling a test.py script containing print("test")right before this and it gets executed normally.

What could be the reason the python script doesn't start and how can I fix it?

Edit: As user jakub recommended changing print("script started")to print("script started", flush=True)successfully gets printed. Including several more of these statements revealed that the script was actually running perfectly fine, it just didn't output anything. Including the same statement within the for loop that gets constantly executed also makes all print() statements previously missing get printed.

The question then turns into: why do the print() statements here need to have flush=True in this script but not in other scripts?
