Solving 6-piece Burr Puzzle

-

Not really computer related, but rather solved with a computer...

I have one of those 6-piece block puzzles that has been apart for some time. I decided to look online to see if I could find a solution. First I learned that it is called a 6-piece Burr puzzle; then I discovered that there are too many different combinations that I would be luck to find a solution.

Then I ran across an IBM Research site on Burr puzzles. After looking through many of their solutions, and not finding a match, I discovered their applet to solve any Burr. I just entered the cuts of each of my 6 pieces, and within seconds it had the solution for me. And if that wasn't enough, it showed me piece-by-piece how to reassemble it.
Truly I am impressed.

Digital Signatures in PDF Do Not Print

Trouble getting the digital signature in a PDF to print? The solution is actually simpler than you might think. With your document open in Adobe Acrobat Reader, click File >> Print.

Now print. That's all there is to it.

Referencing the value of a cell, not its formula

In Excel, I will use formulas quite frequently for my analysis. At times I want to reference the resulting value of the formula for comparison or to feed another formula. Unfortunately, if you are doing a comparison, Excel will try to compare the formula instead of the formulas results. Well, turns out there is an easy way to correct this. If you want your formula result to be a number, then use the VALUE function. If you want the formula result to be text, use the TEXT function. Here is the syntax for each: VALUE(text) TEXT(value,format_text) -- The format_text value can be any format from the Category box on the Number tab (in the Format Cells dialog box) except General. Here is an example of each: =VALUE(MID(A2,46,FIND("&",A2)-46)) -- this actually finds a number beginning with the 46th character of a string, and continues until it finds the ampersand character. By wrapping the formula with VALUE, I can now compare the number to other numbers in my looku

CorelDRAW X4 Crash on Startup

-
I had a fresh install of CorelDRAW X4, and each time I tried to start it, it would crash. After some searching through Google, I found the following fix. Open the folder C:\Program Files\Corel\CorelDRAW Graphics Suite X4\Programs\UIConfig\CorelDRAW Edit DrawUI.xml Find the line <dockpage guidref="bc1e2f70-3b58-41cd-8406-aaa550482972" visible="true" selected="true"> Change visible="false" and remove selected="true" <dockpage guidref="bc1e2f70-3b58-41cd-8406-aaa550482972" visible="false"> Save and close DrawUI.xml Fold down F8 and restart CorelDRAW X4 When prompted to update settings, select OK That did the trick for me. Apparently it is caused by a conflict with MFC dlls that are installed (version 1833) with SQL2008.
