• Is it common practice to put keywords in html markup for SEO?

  - by Joel

  Though it's on the edge of programming questions, I think this is still relevant here, as only those of us actually doing the coding for a site would be considering this. I've been reading more about keyword placement, and it seems to me like a good place to do keyword placement would be in the class and id names chosen for the elements they are representing. I'm not talking about any kind of black-hat keyword stuffing thing but real legitimate use of descriptive keywords for elements. Is this something that is actively done for SEO?

• What potential do you see in Silverlight?

  - by Cyril Gupta

  Silverlight has been available since quite some time, and Silverlight 2 allows .Net programming on the front-end.

What potential do you see in Silverlight judging from the current trends, and what do you think Silverlight will be used for in the coming years?

• Hibernate's version values in Grails app

  - by xain

  I'm looking at a database dump file, and I see many records in various tables with their version number set in values other than 0 (even 94 in one case). I understand it has to do with hibernate locking strategy, but my concern is that today is Sunday, and the site has almost no visitors so is: is this normal ?

• Developers portfolios

  - by Alex

  I'm wondering if you have one, or u know any developer/programmer online portofolio. I know many web developers have one (and in many cases very well designed), but not any C++ developer (for example). On the net there are only some good blogs about some programming language, but in many cases these are extremely poor from a design point of view and i'd say very "nerdy".
