C++ and C are for low level programming (drivers, stable OS components). Stable - that's a first keyword. Customers want to trust to stable component. You don't have experience and they don't trust you. Therefore they will not give you any C/C++ based contract - because of lack of confidence in you.
Java is rapid startup language. It's very fast: a manager of new project will find quickly Java developer (after the bubble there too many of Java developers on the market), quickly model a working prototype (OOP is quick with Java) and find that Jav sucks - it is not scalable up, it is not scalable down, Java interface to databases tends to be very hardcoded, Java is too much OS-independent (so independent that it is too hard to do any useful thing with OS from Java). So, you Java skills have some chance only at moment after the project jast started and before the manager will understand that it's time for something real. And that moment is very short - Java makes all process very rapid.
I advise you something radically different. Begin from a small hardware shop. Take orders without payment with next day of delivery, buy spare parts where they are cheaper, assambly PC, deliver it, take a cash and again and again. Some of customers will start to ask you to install a network, a server, a database. Next natural step - they order a program. Usually small program. Usually not requiring any procedural programming - just simple clients to DB. MS Access with ODBC/SQL will work.
Then things will grow for more complicated and sophisticated demands, you apply more programming skills and demand more compensation. Dont's forget to estimate risks earlier show such risks to your customer on a positive note: you've just saved (or you are going to save) the customer from such risks. That certainly should be compensated well.
What I like on SOHO market - customers don't understand technical things, no religion preferences. Therefore you free from any obligation to do it on Java or other crap. Often no obligation to Microsoft crap. Feel free to use Python, Lisp, Prolog or even OCaml. Install it with Linux and PostgreSQL. And don't forget to give up all source code - as a result of increased confidence in you there will be more and more orders for service, support, training, modifications.
Of cource it's good for you to be comfortable with heterogenious systems and various programming languages and paradigms. But that makes you a real programmer. Not a religiously blind fanatic of Java or VB. Instead - full freedom. Did you wat a freelance programming? You got it:)

"The Samba Team has a number of significant expenses so we have decided to setup a donation system to allow users of Samba to make contributions to help cover the cost of running samba.org and developing Samba"
If a govt wants to save money on open source, than it should act more. My proposal is very simple: the govt must create a budget for all open source packages it uses, and the budget must cover at least all dot-org operational cost. In exchange the govt may get a vote when a team would decide about what features should be in the next release.
The only question is not clear for me yet: in the open source world there are lots of alternatives. What packages will the govt use? For example, GNOME or KDE? I guess GPL is good for govts, but even within GNU there are equal alternatives. For example Emacs and Xemacs.

My logic was simple: if something doubles in CPU now and it will stop doubling later, then it may put CPU (computer) industry into a danger. So, the vendors will create the hype again, now around another CPU parameter. Or even not CPU - just another parameter in the computer system. They will do everything to convience consumers to upgrade their systems (and to pay money).
After 10 years my typical desktop is crazily upgraded. Has it improved my work? I do the same: I edit documents, write programs, run databases.
The change in look-n-feel (TTY-->GUI) made my work more comfortable, but it did not improve my knowledge (abstract thinking?).
And Java just got my CPU and RAM without any positive outcome! Lisp, the child of 1960, still looks more innovative than all that Java hype.
If amount of transistors per chip will stop doubling every 18 months - they will start doubling something else, something they can explain to moms and pops. They can't explain why Lisp machines would improve our world. Bits, transistors - that's simple, it's about speed. It doesn't matter we don't need such speed. Generally - speed is good. So, let's do upgrade!

I can predict that after the crisis the Moor's law (when vendors will fail to double the CPU speed every 18 months) the market will be ready for Moor's law revised in one of the following editions: "CPU bits doubles every N months" or "average computer RAM doubles every N months".
It doesn't matter what doubles every N months, but the consumer must upgrade its system - otherwise we will have a new recession.

Hmm, it might be interesting to have lazy evaluation in Java. I'd like to mix program generators with XSLT - that might bring a new level in XML messaging.

all "that was invented, designed, or written under copyright or patent protection" would be deisgned, produced and supported with IP protection or without it. That's the myth that patents and copyright laws help to invent. In last three decades the amount of pharmacy patents increased in several times, while the amount of really new products coming to the market was in fact slowened down or even really declined. here is just one exmple of it.

You have to reoptimize indices in Oracle either.

Wrong. It's good as it keeps your data consistent.
Using an "IN" clause with a sub-select causes a brute-force join without indexes.
IN is not perfect in Oracle either. Try to use outer join instead.

If you cannot rely on your database - you cannot rely on your data. But unreliable data is just a garbage. You may better use a random generator to read "data" from.
More about "overhead" - don't use Java, Perl or even C. Just code in Assembler - no any overhead. The difference in overhead will be comparable to one between MySQL and PostgreSQL. And same difference in efficiency and productivity of your programmers and DBAs.
What scares most with all these old-time DBs is the cruft they've grown over the years. Complexity. Could somebody testify to its stability?
What you say is completely true related to Oracle. Since early 90s Larry's team forget to fix very strange very same bug in every other release (it's usually fixed right in the next patch): sometimes (seldom) you swap two fileds in the query and the query is failed "due to internal Oracle error".
It proves to me that Oracle RDBMS was not designed well since the beginning, then it was patched very well. But we all know that unless you clean your design up the bug will come again and agaian and again.
By the way, be careful with MySQL - it was not designed to be ACID since the begining. And it was not redesigned well yet. Be aware about potentially lost transactions, consistency and data.

OS X is not free. Unfortunately for both Apple and customers, it is not because Apple makes money on OS X (no way to cover OS distribution expenses with $130), it's because some very unprofessional people make decisions in Apple.
