Golang Reading and Notes for April 2014

27 Apr 2014 , tagged: Go, Golang, Reading List

Last week I attended the Toronto Golang Usergroup Meetup and it was plenty of fun. If you’re in or near Toronto and like to dabble with Go, come out. Oh, and did I mention free pizza? Notes Casting in Go is slightly different than in C related languages. Instead of a cast, you perform a type conversion: var myVariable SomeGenericType = ... casted, ok := myVariable.(MoreSpecificType) // ok is a bool if ok { // Type conversion successful } else { // myVariable does not implement MoreSpecificType } The range keyword when used with two return values does not return references, but rather copies.

JSR-269 Annotation Processing

13 Aug 2013 , tagged: Java, Annotation, JSR-269, Reading List

I’ve been contemplating compile time bytecode manipulation for the Object Mapper Framework for a while now. Compile time instrumentation of classes seems to be a better approach and does away a whole lot of class loading issues, especially in OSGI environments. In any case, I remembered Project Lombok and reading about JSR-269, which was introduced with Java 1.6. It’s an API that allows you to plug custom annotation processors into javac.

Recently I’ve been reading a lot about software development and philosophies on how to write better software. I really enjoyed the Rugged Manifesto as it emphasizes how software is crucial in our world and the responsibilities that come with it. Another great guide is Twelve-Factor App, a list of 12 principles on how to effectively implement and operate applications. And last but not least, Understanding JVM Internals, a really well written cross cut through the JVM, including class file format, JVM structure and stack memory layouts.

OSGI Classloading Reading List

12 Oct 2012 , tagged: Java, OSGI, Reading List

I’ve been doing a lot of reading on how OSGI handles class loading. I’m starting to fully understand and leverage OSGI and I’m trying to keep my framework Object Mapper as compatible with OSGI as I can. In OSGI classloading is very restricted, similar to what happens in enterprisy Java application servers, and completely unlike traditional Java applications where everything shares a single classloader. In OSGI each bundle has its own classloader and what is visible accross the bundle boundaries is subject to strict export rules.
