JSP tricks to make templating easier?
...
Note - it seems the order of tags is important; jsp:attribute must come before jsp:body or you'll get an error. Also I had to set a corresponding @attribute tag to match jsp:invoke to avoid another error. Using GlassFish 3.2.2

Why is std::map implemented as a red-black tree?
...e rebalancing (up to half the depth of the tree).
RB-trees are B-trees of order 4 represented as binary search trees. A 4-node in the B-tree results in two levels in the equivalent BST. In the worst case, all the nodes of the tree are 2-nodes, with only one chain of 3-nodes down to a leaf. That le...
What is the difference between a framework and a library?
...amework embodies some abstract
design, with more behavior built in.
In order to use it you need to insert
your behavior into various places in
the framework either by subclassing or
by plugging in your own classes. The
framework's code then calls your code
at these points.

Pushing each parameter into the stack (the order diverges and depends on each compiler, also some of them are sometimes stored on the CPU registers for performance improvements)

In order to make it easier to consume I wrote a quick API that exposes a number of key source code elements (using statements, types, methods, properties, fields, comments) and is able to rewrite the original C# code into C# and...
Best practice for creating millions of small temporary objects
...lly tons and tons of them, you can use direct ByteBuffers with native byte ordering [the latter is important] and you need some few hundred lines of code to allocate/reuse + getter/setters. Getters look similar to long getQuantity(int tupleIndex){return buffer.getLong(tupleInex+QUANTITY_OFFSSET);}
