Java has become a confusing world. Five years ago, there were few decisions to make once
you started programming in Java—you used AWT for graphical user interfaces, sockets for
network programming, and hacked together everything else you needed. Since then, though,
the APIs available for the Java language have grown, and grown. . . and grown. Now you can
dabble in Swing, servlets, Enterprise JavaBeans (EJB), JavaMail, and more. Additionally,
there are now packages of APIs, like the Java 2 Micro Edition (J2ME) and Java 2 Enterprise
Edition (J2EE). While these packages seem to be nicely wrapped bundles of useful APIs, they
don t help the average developer figure out how to piece together the APIs contained in these
packages. Though it s simple to find documentation on the individual APIs, getting the "big
picture" is difficult, at best. One of the most interesting, but difficult, aspects of Java today is
building Java enterprise applications using the J2EE package.

CBC下寫的串口編程,API函數實例
I wish this site had been around when I was trying to figure out how to make serial communications work in Windows95. I, like many programmers, was hit with the double-whammy of having to learn Windows programming and Win95 serial comm programming at the same time. I found both tasks confusing at best. It was particularly frustrating because I had, over the years, written so much stuff (including lots of serial comm software) for the DOS environment and numerous embedded applications. Interrupt driven serial comm, DMA transfer serial comm, TSR serial comm, C, assembler, various processors... you name it, it had written it. Yet, everything I knew seemed upside-down in the message-driven-callback world of Windows.
