+ Open VS Code with mantis

+ Questions, zoo or otherwise

+ General advice:
    try it and see what happens

+ A few tools
- cat filename
    prints the file to standard output
- hexdump -C filename
    prints a table of bytes from filename to standard output
- Unix "pipes" (command | othercommand)
    funnels the standard output from command to the standard input of othercommand
- Unix "redirects" (command > file)
    funnels the standard output from command to file
- echo -n -e
    -n says "no newline at the end"
    -e '\x78\x79\x7a' says "put those bytes indicated the hexadecimal \x##
        "escape sequence" into the output
- objdump -d

+ Buffer overflow assignment

- What does "hex2raw" do?
