Integrating Scala into JRuby

JRuby Inside — 2008年9月29日 07:06:14 GMT

More and more projects (especially startups) have been choosing to build their software in multiple languages. Rather than using SQL for the database, XML for the RPC and Java for the everything else, companies have learned that sometimes a different language can serve best in a specific area. Ola Bini provides some guidance with regards to methodology in this area in the form of what he calls “language layers”. He suggests that an application can be divided logically into separate layers, and for each of these layers there exists a class of language - be it dynamic, static, compiled or otherwise - which can best accomplish the task at hand. All of that aside, there is one problem which is absolutely assured when dealing with polyglot programming: integration between the languages.

Why I'm starting to like JRuby even though I dislike Java

JRuby Inside — 2008年9月27日 21:37:17 GMT

Among my friends, it's not a secret that I personally don't like Java. During my time at the university, I had to deal with it for some courses, but somehow nobody could convince me to really like the language. With Ruby, it was the exact opposite - I saw a few code examples, read some articles about it and I immediately started to like the language and it's charming way of doing OO like I always wanted it to be.
