• final fields and thread-safety

  - by pcjuzer

  Should it be all fields, including super-fields, of a purposively immutable java class 'final' in order to be thread-safe or is it enough to have no modifier methods? Suppose I have a POJO with non-final fields where all fields are type of some immutable class. This POJO has getters-setters, and a constructor wich sets some initial value. If I extend this POJO with knocking out modifier methods, thus making it immutable, will extension class be thread-safe?

• CSS: a:link vs just a (without the :link part)

  - by Rob

  So we're required to use the following order for CSS anchor pseudo-classes a:link { color: red } a:visited { color: blue } a:hover { color: yellow } a:active { color: lime } But my question is why bother with the a:link part? Rather, is there any advantage to the above (other than perhaps clarity) over: a { color:red; } /* notice no :link part */ a:visited { color: blue; } etc.,etc.

• Compile aspx page "on the fly"

  - by user1122321

  I am trying to build an aspx page at runtime (by another aspx page which finally redirects to the new one). As far as I understand, aspx pages MUST be precompiled before a user can view them. In other words, the aspx page must be compiled to the DLL in the /bin folder. Is there a away to tell IIS, or to order it by VB.NET code, to compile a page before I am redirecting my user to the page? Any help would be greatly appriciated.

  I need to look up all households with orders. I don't care about the data of the order at all, just that it exists.
