Jini and OSGi, yet again
There is a raging debate about OSGi and Jini, yet again. Which isn't necessary or helpful. The two technologies are very different applications of similar design philosophies, and should not be seen as competitors.



Back at OOPSLA
For the first time since 1989, I'm attending OOPSLA. Some things have changed, others have not. Here are a couple of reflections...



He's baaack....
After a long absence, I'm back. With some explanations about why I've been gone so long...



What is XML?
In which, against my better judgement, I try to figure out what everyone means when they talk about XML...



Going all in...
More on objects and networks, but this time I try to make my own opinions clear, if not coherent...



More on languages and objects
If object models are tied to languages, then there are some real implicatons to how we do distributed computing (and how we make objects persistent). If this is indeed the case, then why are we so stuck on language-independent systems?



On Blogging
Having realized that I didn't get the essence of blogging, I resolve to post with greater regularity and with less guilt. Heaven help us all...



Thinking about objects
I've been thinking about objects recently. One of the questions I've been thinking about is whether or not one can make sense of objects in a language-independent way. Herein are some reflections, and what may be the start of a series of posting on the subject...



Election thoughts
Some reflections, not on the current election, but on the process of voting (and the electronic tallies thereof) on this, the eve of our doing it again...



No way to run a judicial system...
Having had some experience in the recent past with the way intellectual property law is handled in the courts, I'm of the opinion that there must be a better way...



Thoughts on Change at 35,000 feet
No one likes to change. But if we continue to solve the same problems (in slightly different contexts) we will be replaces by others who view the problem differently. Or at least that will happen in the area of ubiquitous computing.



How They View Us
One of the most surpising things I've recently become aware of is how we as technologists are viewed by the non-technology public. We are assumed to be able to do the most remarkable things, which often lead to panic on the part of the general public and, worse yet, policy makers. We should do something about this, but I'm not quite sure what.



To type or not to type
My take on the debate of whether typing is needed in a language. Rather than taking sides, I revert to my previous incarnation as a philosopher, and try to see what we are really talking about when we seem to be talking about types.



Worse is worse
The classic essay on "worse is better" is either misunderstood or wrong. And in citing it in our design arguments, we short change both our customers and our craft. I revisit this essay, and reflect...



Knowing and Learning
Some thoughts about knowing, learning, and software design, many of which were thought or written down while watching baseball.
