75% reduction in spam as of Tuesday

-
Brian Krebs, columnist of Security Fix in the Washington Post has been following a San Jose company McColo Corp due to it's contribution to spam. Over the last 4 months Brian has been gathering data, which he shared with the service providers of McColo on Monday. Upon reviewing this material, the ISPs shut down service to McColo. I think the results were bigger than Brian expected -- 75% of all spam has been reduced across the Internet -- that is 75% of all spam was coming from this one company. In his column, Brian has some graphs from a couple different sources that displays these terrific results.
Congratulations and well done Brian!

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. When the Print dialog box opens, look for the "Comments and Forms:" drop-down below the Properties button, located in the upper-right. Click the drop-down and select "Document and Markups." Now print. That's all there is to it.

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.

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...
