Hi,
</p>
<p style="font-size: 16px">
Have I mentioned already that my long-time client, that once a few months asks me to do some urgent work, has done so again? So I am totally busy writing a few small, Dancer-based, in-house web-apps.
</p>
<p style="font-size: 16px">

<br />
<p style="font-size: 16px">
The Alien::* packages make it easy to install non-perl dependencies using the cpan client. Alien::Base makes it easy to create Alien::* packages. As Joel Berger, the author of the module tells us, the module now has a GitHub 'organization' to keep maintain the source code.

Gianluca Casati shows how to configure 'cpan', the standard CPAN client, including some nice features like history and colors. Nowadays I usually use cpanminus, but when I have to use the cpan client this can be a really useful reminder.

<br />
<p style="font-size: 16px">
In this part of his series, Timm Murray explains the RSA public key/private key encryption and message signing algorithm. He also provides a short explanation of what is NP (nondeterministic polynomial time), and why it is important for us.

<br />
<p style="font-size: 16px">
Hashes are one-way mappings of data to something more or less unique. Algorithms that you might have heard about include MD5, SHA-1, SHA-2, are implemented in modules in the Digest::* namespace. Timm Murray explains what are these hashing algorithms, when and how to use them, and what is the problem with birthday parties.

The ref() function will return the type of the reference you passed in. There are a few commonly seen values such as SCALAR, ARRAY, HASH and maybe CODE, but there are several others that we rarely see. In this article you'll see what those references are.
