For years I had used this space as my own personal knowledge base and to share tech news of interest to me. More recently I've moved to share some of my experiences from my very successful career with scaled-support and as a leader and manager.
Robots with a mind of their own
Take a look at this video -- the early stages of robots joining together to make their own hardware.
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.
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.

PC World has a great article that covers many aspects of the days developing the PC at IBM. There is another site, Vintage Computers , ran by Eric Klein. Here is what Eric has to say about his collection, "My vintage computer collection is small by most standards but it contains examples of what I consider to be some of the most significant machines and items from the early days of personal computer history." Mr. Klein has done a great job in providing photos and facts on so many early computers. Another good site for old computers is OLD-COMPUTERS.COM , ran by Thierry Schembri and Olivier Boisseau. I remember my first PC, which I bought used during the summer of 1982. It was a Sanyo MBC-555 that used the 8086, so it was not completely IBM compatible. It came with two 180K floppies, which I could use to run WordStar, and a green monochro
