Devaka started programming with Pascal and BASIC languages when he was 13, and he has been coding with Java since 2003. Devaka got his bachelor's in computer science from the University of Moratuwa, and currently holds SCJP, SCWCD, and SCBCD certifications. He is mostly known as the author of ExamLab , which is a popular exam simulator for SCJP certification.
When he is not wrangling with his JavaEE and enterprise projects, he likes to play with sneaky web application security stuff.

Devaka was made a Bartender in 2010, was promoted to Sheriff in 2015 , and was made a Marshal in 2015 Email

Is there a page where this is documented or mentioned?

That is a flipbook. It may work fine on a web browser, but it doesn't come with anything that supports offline access to the book.

Not sure how well the ranch site is protected but this link goes to an email capture page which takes your details and then doesn't deliver the download. It looked really useful! If you can point me in the direction of any really straight forward PDF creation software that would be really helpful.


I tried to download it from the site. Like you mentioned, it asked me to sign up. I signed up and logged in. Then I went back to the download page. This time I was able to download the file.
What happened in your case?

Jetbrains runs a contest for IntelliJ IDEA theme plugins with gifts ranging from $1000 to $300.

Creating an IDEA theme plugin is a pretty easy work. All you have to do is choose an existing plugin like "Light" or "Dracula" and change a few things like colors, icons, borders, images, etc on a simple JSON file. Here's more about how to create a theme this way:
http://www.jetbrains.org/intellij/sdk/docs/reference_guide/ui_themes/themes.html


  • The top-voted theme plugin will win a $1000 Amazon gift card. This plugin will be featured in the IntelliJ IDEA recommended plugins.
  • The second most-voted theme plugin will win a $500 Amazon gift card.
  • The third most-voted theme plugin will win a $300 Amazon gift card.
  • You can submit multiple plugins. Each will be considered a separate entry.


  • More about the contest here:
    https://plugins.jetbrains.com/contest/intellij-themes/2019

    The contest closes on May 03, 2019.

    I think this would be a good opportunity for ranchers to earn some quick fame and bounty!
