Ozzy

The traffic in Mountain View was mighty fierce driving into work Thursday morning.   My office is next door to Google (Google actually owns the building) and it's across the street from Shoreline Amphitheatre.

So I arrive and see the Building Maintenance Guy in the parking lot.  And I ask him about the crowd...

BMG: Ozzy Osbourne is at the Shoreline.
Don: Really?  The Prince of Darkness is in town?!?  Cool!
BMG: Yeah.  And there are half naked girls with spray paint on their breasts.

So there you go.  (By the way, we're hiring.)


In other randomness:

WFMU (non-commercial New York radio station) has an amazing radio blog.  Do check it out. http://blog.wfmu.org

For example, you can take the 80's pop music quiz.

Taxes Then and Now

I've been in a couple recent discussions about income taxes with some random folks recently, and the people I've talked to all seem to believe that under the Bush administration either the taxes have increased, or that taxes have been reduced only for the wealthy, or that taxes for the wealthy have been reduced while the taxes for the poor have increased.

Of course this is an easy one to check out as the tables are readily available at the IRS web site.

Here's the income tax from the IRS 1040 Tax Table, filing single. I've choosen the years 1998 and 2006, because the former is positioned six years into the eight-year Clinton administration and the latter is positioned six years into the eight-year Bush administration.

Taxable
Income
1998 Tax2006 TaxPercent
Change
$ 10,000$ 1,504.00$ 1,126.00-25.1 %
20,000 3,004.00 2,626.00-12.6 %
30,000 5,112.00 4,126.00-19.3 %
40,000 7,912.00 6,564.00-17.0 %
50,000 10,712.00 9,064.00-15.4 %
60,000 13,512.00 11,564.00-14.4 %
70,000 16,570.00 14,064.00-15.1 %
80,000 19,670.00 16,739.00-14.9 %
90,000 22,770.00 19,539.00-14.2 %
100,000 25,855.00 22,325.00-13.6 %

Note that all the tax rates have gone down, and the average reduction is 16.16% (!!!).  That's quite significant.  And with respect to the present day, the tax rates used to be an average of 19.27% higher.  The greatest reduction was for the lowest income level, where the income tax used to be 33.51% higher.

And note that the four largest tax rate reductions are at the five lowest income levels.

(What's with the glitch at $20,000.00? Probably a correction; the 1998 tax rate at $20,000.00 was already the lowest rate of these numbers, lower than the $10,000.00 rate.)

Actual taxes will be even less today because of things like the child tax credits, which GWB introduced.

So yeah, income taxes are significantly reduced over the last eight years, they're reduced more for the poor than the wealthy, and it's a very good thing...  And, of course, most people will believe the exact opposite.

Tufte Seminar

Charles Joseph Minard's map of Napoleon's March to Moscow

'Went to Edward Tufte's remarkable experimental two-day seminar last week in P'Alto. He covered most chapters of all four of his books in depth, with many delightful stories, insights and examples. Also the story of how he came to self-publish the books. And he included "office hours" segments to answer individual questions.

I came with away these main points:

  • In reference to pie charts, et al: "Graphics can do more than present the obvious to idiots."
  • One must be true to the data and do whatever it takes to present the data in the clearest way possible.
  • People tend to get stuck in the assumed limitations and cliches of a given medium, and one might have to use one's creativity to break free of that for a better presentation of the data.
  • Presentations should serve the data and not the medium.
  • Clarity comes from more information, not less.
  • It's possible to pack an awful lot more information in a presentation than you'd expect.

ET brought in and displayed several rare first editions of books by Galileo, Euclid and others, which clearly proved how data visualization can break free of the most primitive presentation technologies. (And then you can compare that to PowerPoint.)

The books:

All are highly recommended, especially the books.

(The image above is bad copy of Charles Joseph Minard's map of Napoleon's March to Moscow, which has sort of become ET's icon.)
