jOOQ, Java CLI Apps, and Java Performance Tweaks

Wednesday, June 29, 2016
6:30 - 8:30 PM

Presented by

John Childress, Stefanovic Darko, and Jim Bethancourt

My Favorite Feature of jOOQ

jOOQ bills itself as "The easiest way to write SQL in Java". John Childress will be sharing his favorite jOOQ features with us.

John Childress has been developing software since 1998. For the last 14 years he has focused on electricity trading in North America. He loves Java and in particular developing database and desktop applications.

Forgotten Skill of the Command Line Tools/Applications

Command-line applications aka-Console Applications, are computer programs designed to be used from a text interface, such as a shell. They usually accept various inputs as arguments (parameters or sub-commands), as well as options (flags or switches).

Apache Commons CLI and JLine are two of several open source libraries available for Java.

Stefanovic will share his experience in using these 2 libraries for creating a fully functional Interactive Command Line application with features as history, completion on tab, single and multiple arguments, and some more...

Stefanovik Darko is a seasoned developer and has been slinging Java since its creation. He is a Docker enthusiast and recently started the quickly growing Docker Houston Meetup. He has worked in the bioinformatics, finanical, contract, and energy industries and is a frequent HJUG meeting attendee.

Java Performance Tweaks

Figuring out where and how to optimize the performance of your Java code isn't always easy, especially when the code is particularly gnarly. Jim will share some of the insights he's recently learned from improving the performance of an open source refactoring opportunity detection tool over 700%. Yes -- 700% (not a typo). We'll review and discuss the code in question and Jim will share some surprises he found along the way that slow down performance rather than improve it.

Jim Bethancourt is a Sr. Software Developer at Triple Point Technology, and has led the Houston Java Users Group since 2007. He has given talks at the Houston JUG, Houston TechFest, and JavaOne.

Suggested Parking:

Park across the street in the parking garage on Elgin on the 7th floor, taking a parking receipt as you enter the parking garage. Parking is free after 7:00 PM, so you won't have to pay as you exit. Take the elevator to the 3rd floor of the parking garage and walk across the sky bridge. The HJUG meeting will be on the 2nd floor on the left just before you reach the elevator bank.
