On switching languages: things that make you go hmm.

When you switch languages a couple of times a day, you begin
to confuse some syntax and notice differences between the languages. In
one week: get basketball tournament
application working again. (PHP) Get Java app connected to Derby open-source database for my Java
class (handed in to my professor before class meets, but implemented in a
class). Get VB (6, not .net) apps
working for Decision Support Systems class (targeting zip codes) and Databases
class (rental car system). Get VBscript flight-risk scoring system
working. While Visual Basic and VB Script are close, they’re not the same. You
can dim intX as int in VB, but you can only dim intX in VB Script.  (The again, my server doesn’t even let me do option
explicit: The specified 'option
explicit ' option is unknown or invalid.)

And while you can do a Adodc.recordset.recordsize in VB6,
Java (1.5) has no resultSet.recordsize. So when I do a query in VB using ADO, I know how many
records I have; but in Java, I have to do while(recordset.next()) { recount++}
(source).
So my obsolete version of VB knows how many records are in my set, but the
latest version of Java does not. I’m sure there’s a reason for this, I just
don’t know what it is. I haven’t figured out if there’s a recordset size()
function/method in PHP yet. I wonder if Ruby on Rails has one available – I’d
check but the RoR API documentation
isn’t searchable.
