Here is my dilemma as I consider if I should double down on JavaScript and adopt it on the severside. Is there an alternative for the web? and publishing as a whole? We are a small shop. Two people and hope to grow. We publish a web database. Our market is academics, libraries, and scholars. Our Data must be kept in XML. It just makes the most senese. But we are spread over a half dozen different languages. Halfway proficient at all of them, but as we move around to a new project and set one language aside to pick up the other we regress. What we had known must be relearned, the way we were thinking must be retrained. If we created our web services, our internal API's, our production system all largely in the same language we should, I think, we come more proficient and quicker in this language. At the end of the day we need a well functioning, modern web application. So I have no alternative but to be very current in javascript it feels. Might as well set aside our old Java 5 app. Might as well not create a new python project as fun as it is for me when I am the only one that can understand the python. Might as well stop pouring all my efforts into a silo. Why note double down on javascript. A key source of inspiration for this line of thinking is from a conference presentation I saw given from some at O'riely. They were experimenting with their upstream source of their products being HTML5. The HTMLBook[1] project seems to logical enough. Their output is almost exclusively HTML. Be it on the web, the ereader (epub/mobi) or with the PDF. They were using Attenahouse to convert HTML to PDF using CSS. Why mess around with several different languages. Keep it simple, and produces nice things quickly. If they aren't as nice as you hope refactor. With not having to retrain parts of your brain for javascript as you were working on a Python project exclusively for the last month and a half we should be that much quicker.
