 You may need to reboot for this to take effect.  To verify the change.
 The security of encryption depends upon the randomness of the random source used on your system.  If it isn't very random then it may be far more vulnerable to cryptanalysis, and it's known that in the past some dubious agencies have encouraged the use of flawed random number generators to assist with their prurient activities.  Randomness - typically referred to as /entropy/ - is often gathered from factors such as the timing of key presses or mouse movements, but since the BBB won't have such devices plugged into it this reduces the amount of entropy available.
 
 *** On the Beaglebone Black
+TODO: is this relevant? http://www.reddit.com/r/netsec/comments/1x7ias/sha256_authentication_hardware_rng_and_protected/
+
 Computers can't really generate truly random numbers by themselves, since they're deterministic and so operate in a highly predictable manner.  Fortunately, the BBB has an onboard hardware random number generator, which is a physical process which behaves randomly and which can then be read into the computer and stored for later use in encryption algorithms.
 
 Information on exactly how the hardware random number generator on the Beaglebone AM335x CPU works [[http://e2e.ti.com/support/arm/sitara_arm/f/791/t/292794.aspx][seems hard to come by]], but we can later use some software to verify that it does indeed produce random numbers and hasn't been deliberately weakened.

-*** Rules for mailing lists
-A common situation with email is that you may be subscribed to various mailing lists and want incoming email from those to be automatically grouped into a separate folder for each list.
-
-We can make a script to make adding mailing list rules easy:
-
-#+BEGIN_SRC: bash
-emacs /usr/bin/mailinglistrule
-#+END_SRC
-
-Add the following:
-
-#+BEGIN_SRC: bash
-#!/bin/bash
-MYUSERNAME=$1
-MAILINGLIST=$2
-SUBJECTTAG=$3
-MUTTRC=/home/$MYUSERNAME/.muttrc
-PM=/home/$MYUSERNAME/.procmailrc
-LISTDIR=/home/$MYUSERNAME/Maildir/$MAILINGLIST
-if [ ! -d "$LISTDIR" ]; then
-  mkdir -m 700 $LISTDIR
-  mkdir -m 700 $LISTDIR/tmp
-  mkdir -m 700 $LISTDIR/new
-  mkdir -m 700 $LISTDIR/cur
-fi
-chown -R $MYUSERNAME:$MYUSERNAME $LISTDIR
-echo "" >> $PM
-echo ":0" >> $PM
-echo "  * ^Subject:.*()\[$SUBJECTTAG\]" >> $PM
-echo "$LISTDIR/new" >> $PM
-chown $MYUSERNAME:$MYUSERNAME $PM
-if [ ! -f "$MUTTRC" ]; then
-  cp /etc/Muttrc $MUTTRC
-  chown $MYUSERNAME:$MYUSERNAME $MUTTRC
-fi
-PROCMAILLOG=/home/$MYUSERNAME/log
-if [ ! -d $PROCMAILLOG ]; then
-  mkdir $PROCMAILLOG
-  chown -R $MYUSERNAME:$MYUSERNAME $PROCMAILLOG
-fi
-#+END_SRC
-
-Save and exit, then make the script executable.
-
-#+BEGIN_SRC: bash
-chmod +x /usr/bin/mailinglistrule
-#+END_SRC
-
-Now we can add a new mailing list rule with the following, where /myusername/ is your username, /mailinglistname/ is the name of the mailing list (with no spaces) and /subjecttag/ is the tag which usually appears within square brackets in the subject line of emails from the list.
-
-#+BEGIN_SRC: bash
-mailinglistrule [myusername] [mailinglistname] [subjecttag]
-#+END_SRC
-
-Repeat this command for as many mailing lists as you need.  Then edit your local Mutt configuration.
-
-#+BEGIN_SRC: bash
-emacs /home/myusername/.muttrc
-#+END_SRC
-
-Search for the *mailboxes* variable and add entries for the mailing lists you just created.  For example:
-
-#+BEGIN_SRC: bash
-mailboxes = =Sent =mailinglistname
-#+END_SRC
-
-Then save and exit.
-
-*** Rules for specific email addresses
-
-You can also make a script which will allow you to move mail from specific email addresses to a folder.
-
-#+BEGIN_SRC: bash
-emacs /usr/bin/emailrule
-#+END_SRC
-
-Add the following:
-
-#+BEGIN_SRC: bash
-#!/bin/bash
-MYUSERNAME=$1
-EMAILADDRESS=$2
-MAILINGLIST=$3
-MUTTRC=/home/$MYUSERNAME/.muttrc
-PM=/home/$MYUSERNAME/.procmailrc
-LISTDIR=/home/$MYUSERNAME/Maildir/$MAILINGLIST
-if [ ! -d "$LISTDIR" ]; then
-  mkdir -m 700 $LISTDIR
-  mkdir -m 700 $LISTDIR/tmp
-  mkdir -m 700 $LISTDIR/new
-  mkdir -m 700 $LISTDIR/cur
-fi
-chown -R $MYUSERNAME:$MYUSERNAME $LISTDIR
-echo "" >> $PM
-echo ":0" >> $PM
-echo "  * ^From: $EMAILADDRESS" >> $PM
-echo "$LISTDIR/new" >> $PM
-chown $MYUSERNAME:$MYUSERNAME $PM
-if [ ! -f "$MUTTRC" ]; then
-  cp /etc/Muttrc $MUTTRC
-  chown $MYUSERNAME:$MYUSERNAME $MUTTRC
-fi
-PROCMAILLOG=/home/$MYUSERNAME/log
-if [ ! -d $PROCMAILLOG ]; then
-  mkdir $PROCMAILLOG
-  chown -R $MYUSERNAME:$MYUSERNAME $PROCMAILLOG
-fi
-#+END_SRC
-
-Save and exit, then make the script executable.
-
-#+BEGIN_SRC: bash
-chmod +x /usr/bin/emailrule
-#+END_SRC
-
-Then to add a particular email address to a folder run the command:
-
-#+BEGIN_SRC: bash
-emailrule [myusername] [emailaddress] [foldername]
-#+END_SRC
-
-If you want any mail from the given email address to be deleted then set the /foldername/  to /Trash/.
-
-To ensure that the folder appears within Mutt.
-
-#+BEGIN_SRC: bash
-emacs /home/myusername/.muttrc
-#+END_SRC
-
-Search for the *mailboxes* variable and add entries for the mailing lists you just created.  For example:
-
-#+BEGIN_SRC: bash
-mailboxes = =Sent =foldername
-#+END_SRC
-
-Then save and exit.

 Make sure that "*show only subscribed folders*" is not checked.  Then click the *ok* buttons.  Folders will be re-scanned, which may take some time depending upon how much email you have, but your folders will then appear.
