Comment LaTeX + svn works pretty well, actually. (Score 1) 328

I've been using LaTeX with subversion for collaboration for years. The LaTeX learning curve is much more an issue than the subversion learning curve.

But if the issue arises at all -- that means you are collaborating, and hopefully somebody in the group knows how to use LaTeX. And that's the best way to learn LaTeX.

You are thinking about the inclination relative to the sun's equator - however, Pluto's orbital inclination to the Earth's plane is more than that: A bit over 17 degrees.

Earth's own axis is tilted 23.5 degrees, and as there's no obvious integer resonance between their orbital periods, Pluto will at some time be visible overhead at as

high as +/- ~40.5 degrees (17+23.5) - which is surprisingly close to Chicago's latitude of ~41 degrees. So either they got lucky, or someone actually thought about that.

No, not quite. You're assuming that the ascending node of Pluto lines up perfectly with the current axis of the Earth, so that when Pluto is 17 degrees above the ecliptic, it's also at its most northerly. But that isn't actually the case.

Pluto's highest declination (angle above the plane of the Earth's equator) is actually only about 24 degrees. So, in fact Pluto does *not* ever pass directly overhead in Illinois.

Unless you want to wait for the Earth's axis to precess to the right alignment. That cycle takes about 17,000 years.

Submission + - RIP ClarisWorks, 1991-2007

Bob Hearn writes: "With the introduction of iWork '08, which includes the new Numbers spreadsheet, it appears that ClarisWorks, aka AppleWorks, is finally dead. There has been no official cancellation announcement, but AppleWorks no longer shows up under the list of software titles on the online Apple Store, and perhaps more significantly, http://www.apple.com/appleworks now redirects to http://www.apple.com/iwork. Active development on AppleWorks evidently ceased some years ago, but the program continued to be sold. No longer, it seems.

If you are historically inclined, here is a history of the development of ClarisWorks that I wrote four and a half years ago. RIP ClarisWorks, 1991-2007."
