JPA Best Practices and efficient research

Recently, in the course of a evaluation for a project to switch their persistence provider I was doing some JPA research and came across this exhaustive presentation from Carol McDonald: JPA Best Practices.

I am working with JPA now quite some time, but always found that the documentation is not very detailed for such an important subject. Good to find some coherent information and surprising to me that this presentation has only 1851views on Slideshare. Slideshare is actually a really good resource for  quality in-depth information on various technical subjects.

Think about it: its most likely a presentation that was actually presented in front of some people. The presenter has most likely done research on the topic, is experienced on the subject or at least tried out what he is presenting. Hence as a rule of thumb I assume that there is a higher probability of quality and researched information than you find on random places on the Internet.

Its a pity that those presentations often do not to have such a good ranking in the Google searches.

Another good resource in the last couple of months became They made a few things right to encourage and control good answers – and questions. SO would never have the success if it would not have the social status / name branding aspect built into it. Contrary to Slideshare, here Google is up-to-date with their indexing.

    As always very concise post with some pragmatic thoughts.

    I completely agree on the note of SO. Q&A sites have been around for a long time, but Jeff & Co just made a site [being evil]
    that encourages good answerds by enabling dev’s to foster their ego by showing off how intelligent they are.[/being evil]
    Without the social web aspect SO would never be where it is right now. I am not saying this is bad, not at all. When working heaviliy on SO to build up a personal brand, just one thing to remember is: with every hour you are spending on SO to answer questions, you are actually working for free for SO’s to some degree. Even if the data is Creative Commons – they are making *a lot* of money on the ads, jobs, and whitelabelling solutions and the value of those are mostly dependent on the data.

    So and now I’ll head over to SO looking for some JRuby answers ;)

    Nice write up, thanks.

    @Marcel I guess you just have nothing understood what Open Source is about.
