Two Evenings with Venkat Subramaniam

The ACGNJ Java Users Group (facilitated by yours truly ) and the NYJavaSIG (facilitated by Frank Greco ) recently hosted Venkat Subramaniam to speak at our respective groups on back-to-back nights. On March 19, 2018, Venkat visited the ACGNJ Java Users Group at Drew University in Madison, New Jersey where he presented " Twelve Way to Make Code Suck Less ." He discussed why we should care about code quality and defined the First Law of Programming which states, "Lowering quality lengthens development time." Venkat then introduced and discussed his 12 principles to improving code quality along with plenty of live-coded examples. On March 20,  2018, Venkat visited the NYJavaSIG at Credit Suisse in New York City where he presented " From Functional to Reactive Programming ." He discussed the differences between imperative vs. declarative styles, normal functions vs. higher-order functions, and functional to reactive programming along with plenty

Honored to be a Java EE Guardian!

I am happy to announce that my request to join the Java EE Guardians was recently accepted! I first learned about the Java EE Guardians almost two years ago while writing my InfoQ news piece about Oracle's sudden slowdown in the development of Java EE 8 and the response by the Java community. It was during that time the Java EE Guardians were born. Reza Rahman , former Oracle evangelist and now senior architect at CapTech Consulting, led the creation of the Java EE Guardians. I was impressed with their charter and have followed along with their activities ever since. I am honored to be part of a membership that includes notable members such as the father of Java, James Gosling, along with JUG leaders, JCP experts, spec leads, bloggers, authors, and speakers. All you need is a passion for Java EE, now Jakarta EE , and be active in the community. If you have such a passion for Jakarta EE and interested in membership, please send an e-mail to their Google Group .

From Java EE to Jakarta EE

As you may already know, the Java EE name is in the process of a name change. Oracle forced a rebranding after open sourcing and transferring Java EE to the Eclipse Foundation last fall. The Java EE Guardians , led by well-known Java evangelist Reza Rahman , submitted an open letter to Oracle to express their concerns over Oracle's restriction of the name "Java" and the "javax" package names. Rahman conducted two surveys on the rebranding last fall and the results overwhelmingly demonstrated that the Java community supported to keep the Java EE name. Despite all the efforts by Rahman and the Java EE Guardians to keep the "Java" and "javax" names, the process of determining a new name for Java EE will move forward. A new poll to select Java EE's new name recently opened. There are two choices: Jakarta EE Enterprise Profile Once used by the Apache Foundation for stewarding various Java subprojects, the Jakarta name was ret

ACGNJ Java Users Group - 2017 Year in Review

The ACGNJ Java Users Group had a banner year in 2017.  We held our usual 11 meetings (summer break in August) and hosted five (5) well-known Java experts: April 11 - Elliotte Rusty Harold presented "Exceptions: I'm Telling You for the Last Time." May 9 - Victor Grazi presented "Reactive Programming by Example." May 30 - Viktor Gamov presented "The Splendors and Miseries of Distributed Streams." October 10 - Reza Rahman presented "Java EE 8 and Java EE 9: What You Need to Know." December 12 - Donald Raab presented "API Deep Dive: Designing Eclipse Collections." This is indeed a first for our quirky little JUG to host this many Java experts in one year.  The rest of the year featured presentations by our regular "cast of characters:" January 10 - "Technical Overview of Speedment" presented by myself . February 27 - "Getting Started with JavaFX" presented by Scot Jenkins. March 28 - &
