As I am finally wrapping my head around just how useful Gus Mueller's VoodooPad can actually be, I'm getting more interested in tinkering with how it can be extended and made to do my bidding. Dubbed as a "garden for your thoughts," VodooPad is a great place to jot down ideas, lists and notes with a wiki-like document format that makes it dead-simple to link one page to another. Out of the box VoodooPad comes with a lot of great features, but Gus also maintains a VoodooPad plug-ins page with a number of add-ons for making VoodooPad do everything from adding some handy keyboard shortcuts to more complex abilities like rendering math in your documents and allowing plug-in authors to use Python for writing VoodooPad plug-ins.

At the top of my list, however, is the HTML Tools plug-in which allows you to preview the current VoodooPad page as rendered HTML, Textile or Markdown, as well as copy the text you've written as HTML (with styling attributes and all) or Simple HTML with just the plain markup. It's a handy plug-in for anyone who, like me, prefers to compose blog posts (or of course websites) in desktop software in order to take advantage of all the power Mac OS X has to offer, then simply copy and paste the blog post as HTML into their blogging engine or CMS. This Simple HTML feature needs a little work, however, as it isn't creating entirely proper HTML just yet. Lists, for example, are created simply with <br> tags instead of actual <ul> and <li> tags, but it could do the trick for those who aren't exactly trying to pass every HTML validation test available across the web.

The VoodooPad plug-ins are provided for free, though some of them are still PowerPC-only. Demos of the $29.95 VoodooPad are of course available, with a $49.95 VoodoPad Pro version that offers a few key features for power users, as well as a free VoodooPad Lite version for those who don't need quite as much.

You may recall that back at WWDC'05 when Jobs announced the switch to Intel, one of the companies he invited on stage to discuss creating Universal Binaries was Wolfram Research, whose flagship product Mathematica is probably the leading desktop mathematics application. Mathematica has now reached version 6 and the new features are manifold, representing (according to Wolfram) the "most important advance in the 20-year history of Mathematica." Not having much understanding of these things beyond attempting to use it back in college to do my calculus homework for me, it does seem that there's a lot new, including Dynamic Interactivity and "over 1000 new computational functions & interface enhancements."

One downside of the new release for Mac users, however, is that version 6 remains a 32 bit application in OS X despite the availability of 64 bit versions for Windows, Linux, and various Unix flavors. Mathematica 6 is available now at a variety of different price points (education, etc.), with the standard professional version coming in at a cool $2495 for Mac.

Thanks, Stern!

Update: It was pointed out in the comments below that, although it is not enabled by default, it is possible to get 64 bit support on Intel in OS X by following these instructions. Thanks, Geoff!

Just yesterday we posted on the bc command line calculator. Well on the other end of the UI spectrum is Soulver from Acqualia Software. Its authors claim that Soulver is a "plain English" calculator in that you can actually type in certain (in fact very limited) phrases and get answers, as you see above. In general, though, you'll use Soulver as a normal sort of calculator, but with a pleasing, easy to read interface. The expressions to be evaluated go on in the left column and the answers appear in the right, all in a nice clean list. As you can see, you can also open a couple of palettes with conversions and statistics on the entire column. Perhaps ironically, the actual number crunching power under the pretty GUI is the same bc mentioned above. Soulver is not meant to be a particularly sophisticated scientific calculator (though you can define variables, for instance), but rather a kind of "back of the envelope" replacement. It's an unusual concept, but once you get your mind around the idea of it not looking like a stand-alone calculator, I actually think the paradigm works well (and I put my own money where my mouth is on this one).

Soulver is $17.95 and a demo is available.

I'll admit to being just as interested in what Apple has up their sleeve as the next guy, but I've always harbored a chip on my shoulder towards the rumor sites. The constant 'anonymous' sources who wind up all too often being as clueless as they are nameless have always irked me, and James R. Stoup at Apple Matters decided to take Think Secret, one of the largest rumor mongers out there, to task to see just how accurate they've actually been.

Mr. Stoup did the math that was a long time coming and surveyed Think Secret's reports on Apple products between January 05 - September 06. You should really check out the results, as he did a bang-up job detailing everything he found, but to summarize: James found that Think Secret's accuracy can get pretty black and white; either they nail it or they couldn't hit the broad side of a barn with a wrecking ball. He also discovered some patterns in terms of which kinds of products Think Secret typically nabs correctly, concluding that they have a fairly good batting average with Mac hardware and iPods, but their 'inside scoops' on software tend to represent that aforementioned wayward wrecking ball.

Take a look at James' post for the real (and thorough) details of his findings, but don't think he's trying to bash the rumor gurus, Think Secret or otherwise. After all, what Apple fan doesn't hold at least some place in their heart for rumors of what shiny new thing Apple might have coming up? I think James' investigation should serve at least as a reminder that rumors are exactly that: rumors, and not much more. One is merely rolling the dice when reading these sites and building up hopes of a fancy new [insert name here] or a product revision.

With that said, we'll be sure to stay on top of the latest gossip to make sure y'all can decide whether the latest iPhone or media center rumors could be worth that extra wait.
