JConsole tips

From this page and this question on StackOverFlow

Add the following commands on the app:

jconsole -J-Djava.util.logging.config.file=path_to_logging.properties_for_jconsole

or you can use 

[fdemeloj@fdemeloj bin]$ ./jconsole -debug


handlers = java.util.logging.ConsoleHandler

.level = INFO

java.util.logging.ConsoleHandler.level = FINEST

java.util.logging.ConsoleHandler.formatter = \


// Use FINER or FINEST for javax.management.remote.level - FINEST is

// very verbose...

javax.management.level = FINEST

javax.management.remote.level = FINER

Hidden requirements for vacancies



After basically 7 years in Canada, I started to see patterns when I applied to jobs. I remember some years ago if I used my complete name on the process, it would be less likely that a company would call me, mainly because my complete name is not on the <european style> although it is European. Later on, I found some research that actually confirmed this.

Name bias

Affinity bias


Actually, there is a great deal of bias when recruiting.









Cicada 3301 ~ pt 2



After seeing the videos, I started to test some python codes to decrypt the book, or at least verify what was not used.


Therefore I created some python scripts to parse and test some algorithms on Repl.it, which I think is quite useful.

Validation Algorithm

The validation is a simple algorithm that can validate the answer using a dictionary, but I implemented using the Wikipedia validation.






The results I have so far, show that the pages did not use cryptography atbash with any cryptography key.

    First program implemented ~ code

With this program we were able to prove that the first 4 pages and the last page is not using Arbaat ~ with swift [-28 to 28]. 

    Done: Arbaat verification from -28 to28.

     Doing: Implementing now the backward verification [done]

What is missing: the only possibility is to use Arbaat with anagram words

Result: atbash was not used on those pages
