... I'm happy to say that my abstract was approved for this conference, and I will indeed be presenting. Information about the conference, including abstracts...
In the latest versions of Frink, there have been a few new features. * Added documentation on how to integrate Frink into your own Java program. This includes...
I'm glad to say that my talk at the Lightweight Languages 4 conference at MIT was a success. No hardware failures (which is a miracle with my aged and balky...
Hmm. In the presentation you mentioned fahrenheit and celcius as units that you couldn't calculate the normal way, because their zero values didn't really...
... Yup, exactly. I have different ways of representing absolute temperature and temperature differences in Fahrenheit and Celsius. In Kelvin, (or Rankine,)...
I've turned my presentation from the Lightweight Languages 4 conference into more platform-friendly HTML format. I've also turned my notes into a more...
The current release of Frink (2005-03-11) fixes a bug for some values of the function JacobiSymbol[a,n] when a is negative and the range [-2147483648, -1]...
Earlier this week, Sun released Java 1.5.0 update 2, which I'm tentatively calling "the first Java release that actually works." From day 1, Java made much...
I'm working on implementing interval arithmetic in Frink. Interval arithmetic is cool--instead of a number being a single value, an interval can contain a...
(i'm about to launch into an unfounded ramble through ideas, which may not go anywhere useful. feel free to skip to that much more interesting email from your...
... To paraphrase Kirk's comment about Spock, "your unfounded ramble is as good as another man's well-considered reply." ... Actually, multiplying a scalar by...
... What about A .. B? Examples: for i = 0 .. 100 ; do fa[i] = f[i] + f[i-1]; done lunchtime = 12am .. 1pm if x in lunchtime; then do_lunchtime_event ; endif ...
... Ah, i didn't grok what intervals really were. I was thinking of them only in terms of their outer bounds, and simple calculations like + 2. Realizing that...
... Marcus Downing also suggested this (and a few similar options) and I addressed it in my last reply. I understand if you didn't plow through that whole...
... Hmm... well I'd definitely go with an object interface, just in case you wanted to add probabilities to the intervals next, or maybe define intervals in...

Wow. A fuzzy calculator. That really would be impressive. ... I did actually wonder about using a syntax like this, if no symbolic one presented itself. I...
... That would be neat, but hard! Actually, maybe not that hard. If I understand the intent correctly, you could do something very similar by defining a few...
I'm happy to say that Frink now has a working implementation of interval arithmetic. Programs that you've written in the past might now start automagically...
Very cool. Although I seem to remember suggesting the same thing a few years ago to Alan, except I called it a error value. Or am I wrong, and an error value...
... That 'main' value is lost in certain operations, or? The problem is, of course, the non-monotonity (sp?) of certain (continuous...) operations. That means...
... Interval arithmetic can be considered to follow somewhat different rules than traditional error analysis. Usually, in traditional error analysis, it's...
... The "main" value should only be lost if you perform an operation with 2 intervals, one of which doesn't have a main value. In this case, it's impossible...
I've released a couple new versions of Frink with some additional support for intervals, along with some various improvements and major internal rewriting. ...
I was just watching Star Trek: The Next Generation, the episode "Silicon Avatar," where our old friend the Crystalline Entity attacks a planet, as he is wont...
Alan, I strongly discourage halting the program due to overlapping intervals. Yes, it is kind of hard to linearize this relationship (ok, we do not exactly ...

... Just a point of clarification--the sentence above is potentially ambiguous too. :) Are you saying that: a.) You would rather have the < relation yield...
... Well, there is no hole. The order is partial, that is all. ... I am promoting Prof. Moore's definition, i.e., (1). ... Yes, that is the partial nature. The...
