Hi Everyone,

Yesterday, I wrote a post that collected the different information for using Warbler to compile and package Ruby code + JRuby into an executable JAR that will run anywhere. I will probably need to do a second page that talks more about the configuration, etc. If you're keen, please take a look [comments welcome]  
[https://notepad.onghu.com/2021/jruby-win-day2-creating-jar-files/](https://notepad.onghu.com/2021/jruby-win-day2-creating-jar-files/)

Now, the question:  
When the created JAR runs, it unzips and creates a folder and a file in the TEMP directory. These are not removed automatically. I am trying to determin if this is expected. If this is expected, just be sure that if you’re running a few jobs automatically every minute on a schedule, you will add approximately 25MB – 30MB to your TEMP directory each time. We had a problem on a server once due to that and I'm looking to see what advice I should include for the reader.

Thanks & Best Regards,  
Mohit.

Good Morning,

I am very new to Ruby. I have tried to download KIDSRUBY but was  
unsuccessful. Do you know if KIDSRUBY is still available?

Hi Bernadette,

I have no advice for you other than what Ken responded earlier:

What are you trying to do with KIDSRUBY and I wonder if regular Ruby could help you with it now?

Best Regards,  
Mohit.
