    1. CO@Óscar López: you have answered the "real" knapsack but not his problem, which seems simpler since that there's apparently no value/weight distinction in the OP's problem.

    2. CO*"the installed Java on Linux"* [sic] doesn't mean much. You're not forced to be root to install Java on Linux and hence every user can install as many JRE (or JDK) as he want in his account. Switching from one JRE to another is as simple as doing: *export PATH=~/jdk1.6/bin:$PATH*. So you can have one user having, say, a 1.6 32-bit JVM and another having a 1.7 64-bit JVM. On correctly configured systems it's impossible to know which Java is installed in another user account. I'd rephrase: *"Is there an uniform way to detect which Java version is available from a user account?"*

    3. CO@xanatos: when I'm talking about *"much faster"* back in the days I'm talking about the *bitwise* taking one or two CPU cycles and the modulo, using the remainder of a *div* in a register, needing close to CPU 20 cycles if not more. So when I meant *"much faster"*, I was talking about nearly *an order of magnitude faster* (10x if not much more, depending on the hardware). I'm not talking about a mere 10% which, as *delnan* pointed out, may be optimized automatically anyway nowadays ; )

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
