Anyone read this:
Print ISBN:978-1-4493-1428-6 ISBN 10:1-4493-1428-7

??

If so, would you recommend it?

If not, will you recommend something along that vein?

Thanks!

Sorry. I've looked through 0-596-00789-2 a little, and a few chapters of 
978-1-4493-1640-2 and 978-0-596-52708-2. I don't really have much call 
for that extra mile, yet.

I read the 2004 edition (several years ago). It was written with MySQL 4.0 in mind. There are a couple of parts in the book that talk about MySQL 4.1 and 5.0, which were in alpha or maybe beta at the time. 


If you are comfortable with MySQL, but really want to get past the basics and start considering things like which storage engine is best for a particular situation or how to make sure you are getting (and keep getting) good performance, then the book is good.

On the schedule is me, going on about how I automated flow onto the 
Purdue Perl Mongers twitter feed, @purduepm, with possible talks from 
Mark on Perl6 Infix operators or controlling a robot chassis with Perl 
5. If you have a talk idea, preferably Perl-related but not necessarily, 
please tell the list or put it on the PPM wiki page.

Maybe I should write a list notifier using Template Toolkit and 
Email::Simple, then present it. Or, maybe someone else can....

I would like to hear him speak, but I may be cringing the whole time.

My suggestions:

1) know what you want the site to do, both in mobile and in general, and 
what can be held back
2) have each block have a class or ID that you can access with CSS
3) using media queries, only display the essentials once a page is down 
to hide the less essential parts

Look at Twitter's bootstrap for the css. It basically gives you a
responsive site for free. That is assuming your html markup and such
amenable to such css changes.


Take a look at:

http://blogs.perl.org/users/joel_berger/2012/03/mojolicious-bootstrap-awesome.html

He doesn't go into much detail but he based his site on mojolicious but
CGI is really just the backend. Your html/css/javascript is what really
makes a site mobile friendly.

SUMMARY---USE THIS CODE TO DECODE IT

Use this code to decode it.  Perl may have something better that handles
the three parts of the key bundle behind the scenes but I think this may
work like you want.

#!/usr/bin/perl

use strict;
use warnings;

use Crypt::DES;
use MIME::Base64::Perl;

use feature 'say';

my $string64 = 'RL5ZJUYNxNMnqa9wusptOSuDRAgIJ+mJ';
my $key64    = 'L1uu9NwccM0TJWTmUj2heiO/WHMl7wKP';

my $string = decode_base64($string64);
my $key    = decode_base64($key64);

my $key1 = substr $key,  0, 8;
my $key2 = substr $key,  8, 8;
my $key3 = substr $key, 16, 8;

my $cipher1 = new Crypt::DES $key1;
my $cipher2 = new Crypt::DES $key2;
my $cipher3 = new Crypt::DES $key3;

my $output = '';
while (length $string)
{
    my $t = substr $string, 0, 8;
    $output .= $cipher1->decrypt($cipher2->encrypt($cipher3->decrypt($t)));
    $string = substr $string, 8;
}
say $output;
            

DETAILS---MISCELLANEOUS MUSINGS---SKIP UNLESS YOU'RE REAALLY INTERESTED

>From http://csrc.nist.gov/groups/STM/cavp/documents/des/tripledesval.html
    Notice: The DES Transition Plan has ended as of May 19, 2007. The
    DES Transition Plan addresses the use of single key DES by Federal
    agencies, which are incorporated in cryptographic algorithms. Therefore
    Triple DES Keying Option 3 (Key1 = Key2 = Key3) is no longer Approved.

>From reading I've done it looks like single and double DES are no
longer recommended but triple DES is still used.

The key is 32 characters long and each character is base 64
encoded so there are 32 * 6 = 192 bits in the key.

According to http://en.wikipedia.org/wiki/Triple_DES#Keying_options
    Triple DES uses a "key bundle" which comprises three DES keys, K1,
    K2 and K3, each of 56 bits (excluding parity bits). The encryption
    algorithm is:
        ciphertext = EK3(DK2(EK1(plaintext)))
    I.e., DES encrypt with K1, DES decrypt with K2, then DES encrypt with K3.

Continuing with http://en.wikipedia.org/wiki/Triple_DES#Keying_options
    Decryption is the reverse:
        plaintext = DK1(EK2(DK3(ciphertext)))
    I.e., decrypt with K3, encrypt with K2, then decrypt with K1.

See http://www.cryptosys.net/3des.html for instructions of how to
extract K1, K2 and K3 from the 192 bits in the key bundle.

Once you've got K1, K2, and K3 you may want to try using
MIME::Base64::Perl to do the 
        plaintext = DK1(EK2(DK3(ciphertext)))
