comment Why system RAM can not have a battery backup in the same way as a CMOS?
Probably your definition of "negligible" doesn't match the actual consumption vs battery capacity vs time. Assuming 10W and 1000 hrs of standby, you need a 10 KW battery, which is about 4 "C" size NiMH, plus charging circuitry, voltage conversion, etc. Of course, one could just use static RAM and have no battery consumption when off.

comment Is there an Excel formula to identify special characters in a cell?
Is there a particular reason you're doing this text processing task in Excel? Even limiting oneself to Microsoft Office tools, it's a fairly simple search & replace in Word. Table with two columns, original filename and processed file name.

comment ITSUMIF Criteria for Cells That Don't Match a Condition
Sort by category, use automatic subtotal. Paste the subtotal lines as values, then resort back by date. If that works for you, save it in a macro.

comment Linux - Set Subdirectory as Root for a user/group
You can set up the chroot environment for the user -- actually, set it up for several users -- and have their initial shell be a program that chroots and execs a real shell
