A Deep Dive Into the Transformer Architecture – The Development of Transformer Models

Deploying Spring Boot 2.x Applications in WebLogic 12.1.3.1 Using Gradle Build

Apr 04, 2019 · Anish Panthi

If you exclude spring-boot-starter-logging do you get any log output either from Spring or your app code? If I do a similar exclude in my maven pom.xml, when running locally with embedded Tomcat I don't get any log output and the app fails to start? (putting spring-boot-starter-logging back then it starts locally, but fails to deploy on WLS12c)

Installing OpenJDK 11 on MacOS

What version of MacOS are you running? What version of Java do you have installed (and what type is it, is it an OpenJDK build, or?)

I should give that a try. I'm familiar with brew and macports and I think they both have ready to go packages too

Pointers in Java

Jan 24, 2016 · John Vester

References are also passed by value. There is no pass by reference in Java.

Pointers in Java

Jan 24, 2016 · John Vester

Also, please review the excellent answers and examples on this thread on StackOverflow showing how Java does not support pass by reference: http://stackoverflow.com/questions/40480/is-java-pass-by-reference-or-pass-by-value

Pointers in Java

Jan 24, 2016 · John Vester

I think you're missing the point in what is meant by 'pass by value' vs 'pass by reference'. Java only supports 'pass by value' method passing semantics. It's stated so in the Java Language Spec, section 4.12.3 item 4 (Method Parameters). https://docs.oracle.com/javase/specs/jls/se8/html/jls-4.html#jls-4.12.3

For a definition, see: https://en.wikipedia.org/wiki/Evaluation_strategy#Call_by_reference

Pointers in Java

Jan 22, 2016 · John Vester

The confusing choice of terms in Java is that references are also passed by value. There is no pass by reference in Java.

Is Microsoft set to become the GM of the software industry?

Aug 17, 2009 · Kevin Hooke

When has Microsoft ever done anything that it thought was good for America, or anyone other than themselves for that matter? That doesn't sound that's part of their business model, and anyway 'embrace, extend, do something good for America' doesn't have quite the same ring to it

Why Django and Python just won my heart

Feb 09, 2008 · truebosko

"... in a weeks time ... I managed to: Create a fully functional website ..." 1 week? I can't help think that if this was Ruby on Rails or Grails, you would have got this far in < 1 day. I'm not a huge advocate for RoR, but being a Java developer Grails makes getting a working web-app up and running a trivial exercise.
