Another Contender For the Land Speed Record 85

We've been following developments with the British-led Bloodhound SSC, a jet car aiming to hit 1,000 mph in 2011 and shatter the land speed record. Now reader Thea Chard writes in about a rival project from Washington state, one aiming at 800 mph before the end of 2010 — still plenty fast enough to break the record. "For the past 12 years Ed Shadle, 68, Keith Zanghi, 55, and their 44-man team have been racing to break the world land speed record with the North American Eagle, a converted 1957 F-104 Starfighter 'turbojet car.' Although the team is rushing to beat out their biggest contender, Bloodhound SSC from Great Britain, whose team leader holds the previous land speed record and has secured much more financial support for the project, Shadle and Zanghi hope to run the Eagle at around 800 mph later this year, breaking the sound barrier and setting a new world record for fastest land vehicle."

I'll second this comment. Though not a professional genealogist, I am the family historian. Once you move more than 3-4 generations back you will exceed the scope of family lore and need external information to help you figure our where you come from.

For example, family lore held that my great-grandfather (GGF) immigrated from Wales. However, according to the US Census, it was his FATHER that immigrated. His mother came from Ohio. Once I knew that I was able to find my GGGF and that between 1900 (are you a US citizen = no) and 1910 (are you a US citizen = yes) something important changed. From that I was able to track down his citizenship application and find the town where he was born. Now I've jumped the pond and am working to find his parents. Fun times!

All of this started because the US Census asked several critical historical questions such as place of birth for you and your parents, parents names, age, marital status, citizenship, and occupation.

The fact that we are no longer asking these questions, whether for fear of offending or political correctness, is a travesty to future generations.

There's a book that's 2200 years old. I don't mean the story (or in this case, poem) is 2200 years old, I mean the *piece of paper* (or in this case, papyrus) on which someone copied the (2400 year-old) poem is 2200 years old. In the right conditions, archival quality paper will last a *lot* longer than any electronic medium.

Comment Since when is a year = 2 mod 4 EVER a leap year? (Score 3, Interesting) 342

Guys, it's really not that hard:
GregYear <- (appropriate year for start of Gregorian era in locale)

IF (month = 2 AND year MOD 4 = 0 AND (year < GregYear OR year MOD 100 > 0 OR year MOD 400 = 0))
{MaxDayForMonth <- 29}
ELSE IF (month = 2)
{MaxDayForMonth <- 28}
ELSE IF (month IN (4,6,9,11))
{MaxDayForMonth <- 30}
ELSE
{MaxDayForMonth <- 31}

Comment Re:Something from Nothing (Score 1) 426

I certainly hope you don't characterize "real estate" as "real property." The owner of real estate owns something just as abstract as the owner of Intellectual Property does - the right to use and occupy land. Ultimately, all property is abstract: if you hand me a five dollar bill to look at, does it become my property because it is in my possession, or does it remain your property?

Comment Re:Did MY Tax Dollars Pay for This? (Score 1) 426

I believe such monuments are usually funded by subscription by private organizations; and I find evidence that such is the case for this Memorial. So, NO, your tax dollars did not pay for this, though it is on public land; I do not know if the Federal government maintains the site or a private organization does so (as is the case with e.g. Monticello).

Comment Data Structures, Algorithms, and Design Patterns (Score 1) 293

Savitch's book is superb as a textbook. You won't find many other books that are that good. The two things I'd suggest learning about are data structures/algorithms and design patterns. For the former, there are a lot of text books, but the good ones are advanced and expensive (for instance, Cormen, Leiserson & Rivest, *Introduction to Algorithms*), and the inexpensive ones are poorly written. You might try the O'Reilly book "Algorithms in a Nutshell*. For the latter, there are a number of books - a good intro book is *Head First Design Patterns*; the book of books is the so-called Gang of Four book that introduced the idea, *Design Patterns* by Gamma, Helm, Johnson, and Vlissides.
