Straight to Voicemail, If Unknown - A simple free method for blocking scam calls and robocalls

Problem: How do I block scam calls and robo calls? Premise:  If the call is important, the caller will leave a voicemail.

We put every number we know into our caller ID systems.

If a number we do not recognize, or a number that blocks caller ID calls, we always let the call go to voicemail. Callers that really want or need to talk with us will leave a voicemail. If we are not interested, we delete the message.

This process initially upset some of our parents, but we have not had to deal with a robo or scam call in some time, since the calling computers almost never leave a voicemail. Our parents are now used it and leave messages. Sometimes, we pick up as soon as they start talking. Our friends mostly communicate via Facebook, internet chat tools, and email these days, so they are used to asynchronous communication and don't mind leaving a message. The political parties and charities we support do leave messages. We call them back to donate or express our support.


A script to split a file tree into separate trees - one per file extension present in the original tree

PurposeHave you ever had a tree of files from which you only needed certain types of file? For example, I had an iTunes library with some Apple files from another iTunes account combined with a large number of MP3s. I wanted to pull out the tree of MP3s only. You can make such a tree by passing a combination of flags to rsync that make it do an exclusive include.How?Pass the following flags to rsync to make it do an exclusive include for files fitting a certain globbing pattern. Fill in for the variables of course, if you want to use this line alone.In particular, this rsync line: rsync -av --include '*/' --include "*.${extension}" --exclude '*' ${source_directory}/ ${top_directory_of_results}/${extension}/ The script: ==========================================================

This tool reads a directory of files that have extensions and then copies each type of file to its own tree.

The location of each file in the subtree matches that file's location…
