One of the things I really enjoy at the moment is the recognition and adoption of agile programming as a fully fledged powerful way to deliver quality software projects. As its figurehead is a group of very talented individuals who have created the agile manifesto...

An acronym occurs when the first letters of a phrase are combined into a shortened form that becomes an abbreviated way of describing the original. In science, they are often used to take a fairly verbose and complex concept, such as Light Amplification by Stimula...

Hippocrates, one of the founding fathers of modern medicine, realized that those who trained to become physicians were not only able to use their skills for good and for progress, but also might be inclined to misuse all they had learned. To protect against such a...

Imagine you are a contestant on a TV game show and your grinning quiz master pops the question: 'Name the one thing you most associate with Google?' Think about your answer - write it on a card (don't show me yet). Turning your card over, it's likely to be one of ...

One of the most fundamental design principles of Java is captured in its motto 'Write Once, Run Anywhere.' It describes how a .class file encodes its instructions at the bytecode level, allowing portability between different machines that, through a specific vir...

Once upon a time, software developers wrote code and ruled their kingdoms. Good programs had few bugs and performed their tasks efficiently and with style. The elite programmers went on to become designers who would lead others in their wake, instilling in them ...

Often in software I find myself preaching restraint to those who wish to move platforms for no apparent reason than to keep up with the IT fashion industry; however, even harder than the silver-bullet chasers is dealing with organizations where change is required,...

The other day when I arrived at work my phone's voice mail light was lit up. Cool, except that after pressing the voice mail button I was asked to enter my password. Issac Asimov's first law of robotics states that 'A robot may not injure a human being or, through...

In a recent presentation I attended, the speaker warmed up with a couple of bulleted lists that outlined the agenda of the session before moving onto his third slide that was clearly many days, work of stitching together powerpoint glyphs and figures in a sort of ...

A number of very significant development efforts are underway that bode well for Desktop Java's future. On the language side is the Java FX script project http:// www.sun.com/software/java fx/index.jsp. Java FX is neat because it provides a high-level scripting inte...

Mike Milinkovich, executive director of the Eclipse Foundation, has been kind enough to answer some questions for Java Developer's Journal. Rather than rattle off the usual ones about the name, about why Swing wasn't used, or how much influence IBM still has, Mike...

Having attended two conferences in the past three weeks and seen untold presentations, I've come to the conclusion that irrespective of the subject matter, each presenter invariably falls back on the same technique to impress the audience: to rely on the skills ...

Mike Milinkovich, executive director of the Eclipse Foundation, has been kind enough to answer some questions for Enterprise Open Source Magazine. Rather than rattle off the usual ones about the name, about why Swing wasn't used, or how much influence IBM still ha...

In Bernard J. Baar's book 'A Cognitive Theory of Consciousness,' he describes the brain as having a single conscious area that can be occupied by one thought at a time. The unconscious part of the brain stores memories and experiences and, like the conscious brain, ...

At the moment there seems to be an extremely unhealthy obsession in software with the concept of architecture. A colleague of mine, a recent graduate, told me he wished to become a software architect. He was drawn to the glamour of being able to come up with grand...

The phrase 'not invented here,' or NIH, when applied to technology, describes a resistance by a group to use a perfectly valid solution to a problem they're encountering because they'd rather build the answer from scratch than adopt something existing that already...

At the annual Alan Turing memorial lecture given by Grady Booch in London last month, he chose as his subject, The promise, the limits, and the beauty of software. It was an excellent address in which one of the themes was that for each of the incredible advances ...

The Standard Widget Toolkit (SWT) is the GUI toolkit used by Eclipse. The same folks that worked on the Common Widget (CW) library for IBM/Smalltalk developed it, this time for Java. Now, it's maintained as part of the Eclipse Platform project and distributed unde...

I am always in awe of people who develop hardware. They're the real engineers of our profession, the ones pushing forward the speeds at which things work, their size, and their connectivity. For example, in 2005 there were more computer chips produced worldwide th...

The year 2006 marked the tenth anniversary of the Java language and for me is the most significant in its history. The most important event was the announcement that a GPL version of Java SE will be available sometime in the first half of 2007. If nothing else, all ...

Ted Nelson, inventor of, among other things, hypertext, once lamented that software development today is at the same evolutionary stage film making was at 100 years ago. Back in the 1900s, when the technology of film production was in its earliest stages, the came...

Abstraction, as defined on dictionary.com, is 'considering something as a general quality or characteristic, apart from concrete realities, specific objects, or actual instances.' It's a powerful concept that underpins software reuse. When you implement a problem,...

Recently I was able to talk to Tim Cramer, executive director of tools at Sun, about NetBeans. Tim started in engineering doing supercomputer compiler work, moved to more generalized hardware compiler work, and naturally moved to JIT/dynamic compilers in Java du...

In 1996, Sun created Java and the terms under which it is distributed. Since then, the Java Community Process (JCP) has emerged, allowing companies to participate in shaping language changes, but the ownership of trademarks, licensing agreements, branding, and oth...

Computers can generally be characterized into two types: ones that are designed to have more than one user attached and those intended for a single user. In the beginning almost all computing was done on large multi-user machines, partly due to their expense, whic...

I've used the map to store things in a keyed fashion and want to iterate over the keys and the value for each. Problem is, each time I do it I find myself thinking how inefficient it must be. The keys iterator returns the keys so it has to walk the keys, however t...

One of the phrases that has always puzzled me is 'business logic'. It seems to crop up a lot in presentations, articles, sales pitches and so forth. The one I saw it in most recently was a talk about how great web servers are because they keep all of the business ...

First one today from 'Visa services' who'd insisted I entered my credit card details and password on their web site today to avoid irreversible instant deactivation of my account. Only problem is I don't have a Visa card and their URL had a Zambian IP address so I...

The problem with the web has always been that despite anyone trying to convince you otherwise, it's a page based latency bound transaction model that is a dressed up graphical mainframe. Works well because the transport protocol is neutral and ubiquitous allowing ...

Back in 1996, Java was originally hailed as a way of making the Web more appealing through applets, and, with its 'write one, run anywhere' philosophy, as the holy grail for desktop apps that would be truly cross platform. The truth is that both were oversold at t...

When the phrase Web 2.0 came out a number of people were sceptical about what it actually means. Being objective, it's a collection of disparate technologies that make web sites more usable. Everyone wants their user interfaces to look and work better, and most of...

Some of the words I dread most in a meeting are: 'What if ?' They're fine in the present tense of 'What if a user tries this option?' or 'What if the database read fails mid flight?', but as soon as the future tense is introduced I begin to worry. 'What if the dat...

When someone in a corporate boardroom decides what their IT strategy is going to be, it isn't based on what language or software architecture they will use, but on how a system can provide value to their business. Very few organizations buy their hardware and OS f...

Recently I was called in at the last minute to help out with a sales opportunity. The team had been working hard on a proposal for many months, during which they'd built a large working prototype system that talked to the customer's actual back end systems using web...

In Java's early years, the language received a lot of flak from its opponents over performance. Java turns its .class file bytecodes into machine instructions (MI) at runtime, something that costs cycles and is slower than a fully compiled language that creates th...

I have just finished reviewing the book Open Source Development Tools for Java, which provides excellent coverage of such topics as log4J, CVS, Ant, and JUnit. There is a chapter on UML tools though in which the author almost apologizes for the lack of good open s...

One way in which technology is adopted is when an existing process is automated and made more efficient, cheaper, or reliable. Another is when a technique or innovation is applied to an existing process to drastically alter the way it occurs. The disadvantage of t...

Ajax is an odd beast, because it gives a very rich user experience when compared to a traditional web page (Yakov writes wonderfully about this at http://java.sys-con.com/r ead/163232.htm), however apart from that it?s hard to figure out what is so great about it. Go...

'If Java is to remain at the forefront of technology for the next 10 years,' writes Joe Winchester in his Java Developer's Journal column, 'it needs to find a way of decoupling API calls between internal code and external blocks, perhaps even introducing soft typi...

Rumors of this name change have been flying around for a while but it is now official - the brand has been kicked into the bucket and replaced instead with a more verbose name and 'Platform.' This probably isn't such a bad thing. The 2 was sort of a year 2000 thin...
