The changing landscape of programming

Do you write code? Not can you write code, but do you?

Max Goff begins his final installment in his href="">
Blacksmith and the Bookkeeper series with that challenge. He
includes an excerpt with details of the Apollo Guidance Computer (AGC) used
in the moon missions and launches into a look at postmodern (pomo)
computer programming.

Alan Kay is delivering the Turing lecture in a couple of weeks at
this year's OOPSLA conference in Vancouver. Kay often talks about the
programming that was done decades ago on constrained devices and
challenges us to go further with our applications today. Read the
details of the AGC and consider the power of the cellphone that you
carry in your pocket. The possibilities are pretty exciting. As we
write to abstraction piled on framework piled on large collections of
libraries, what are we gaining and what are we losing? Take a look at
Max's article and weigh in in the talkback section.

In today's Weblogs,
Bruce Tate blogs about href="">
Time, wisdom, and AOP. He says that "we need to look for ways to
use AOP with training wheels. We'll see limited techniques that
simulate AOP behavior, like interceptors. We'll see frameworks that
let you configure prepackaged AOP services, like Spring. With
technologies like these, we'll be able to use limited AOP power, and
get some limited benefit. All of this time, we can more safely collect
the wisdom that will make it possible to push AOP from small,
expert-laden successful projects to the mainstream."

Andreas Schaeffer follows up on his previous blog entry with his href="">
Proposal to fix the Cloneable Problem. Let him know if you think
he has it this time.

Also in Java Today
, looking to get started with
Spring? Take a look at the OCI article href=""> Spring
MVC. Paul Jensen explains "Using the Dependency Injection
framework as a foundation, Spring adds support for many common
aspects of application functionality including persistence,
transaction control, AOP, error handling, and distributed

Underneath the JTable is the TableModel. As Michael Abernethy
writes in href="">
Ease Swing development with the TableModel Free framework, "
nearly all of the code in each TableModel is identical to the code in
every other TableModel, and the code that is different doesn't really
belong in a compiled Java class anyway." He introduces "the framework
and code that makes up the TMF [TableModel Free] framework -- a
combination of code that I've written and commonly used open source
projects. With this framework, developers can reduce the size of a
TableModel from hundreds of lines of code to a single line, and put
the important table information in an external XML file."

In Projects and
, the href="">JavaDesktop Community's href="">Swing
Component Depot contains links to dozens of high-quality
component collections, from widget collections like href="">JGoodies to specialized
components like charts, graphs, and maps.

Whirlycache is a
fast, configurable in-memory object cache for Java that speeds up
websites and applications by caching objects that would otherwise have
to be created by querying a database or by another expensive

Is it time to href="">
add closures to Java? In today's href=""> Forums,
Ahoma writes "Yes it is syntactic sugar a lot of people say, but take
a look what you can do with Groovy. You can express your algorithm in
a lot less lines. The code becames more readable, and in some cases it
can be describing an algorithm a lot better. Closures are nothing more
than inner classes that encapsulates a sequance of code."

DGriffit would like to see href="">Batch
File Operations. "One thing I've been hoping for is a standard
utility library which would allow the definition of file sets (via
regexes, recursive traversal of directories, inclusion/exclusion,
etc.) and operations on those sets of files (delete, move, copy, all
the usual suspects). "

What if you only had to href="">download
those parts of the JRE that you needed? Cowwoc writes "The key
here is providing end-users with a "download-on-the-fly JRE". That is,
ship Java Webstart with the absolute minimum dependencies. If it must
be a native installer, so be it. This new version of Java Webstart
would be smart enough so that if my application tries using a JRE core
class/package that has not been downloaded yet, it'll go to Sun's
server and download it automatically. As time passes, the user will
get more and more classes installed on their machine and more
applications will run out-of-the-box without having to download any
JRE classes."
