Does anyone know of a source where the 555 Timer Cookbook is available in PDF form?

I got the same thing.  Could be a false alarm, but I'd be careful.

I was an RF applications engineer and worked with Walt at Analog Devices in the late 1990's. (And a bunch of other cool folks who basically invented SDR as we know it). It was kind of odd to be in a class with him learning about some new ADI chip from a designer. Walt was a Field Applications Engineer FAE at the time. I am not sure that he realized how influential that little book was to so many of us! Another of his classics was the OP-AMP book.

This worked for me and I have two levels of security.

I always scan before opening and before reccommending. Sometimes it's a string of characters in the file that only looks suspicious as others suggested.

If one does not mind losing the OCR feature of the file, it can be opened (at one's own risk) in reader then printed with Microsoft "Print to PDF" feature, a built-in printer in windows 10 or any other tool.

The new printed file will be completely different on the inside. The suspected file may then be deleted. The new file will be bloated to about 2x the size in this case because all that OCR'd text will be stored as images of the text, not as actual text. The change can be seen in a hex editor.
