For all the NetSec people out there, it is worth learning some scripting language to make your life easier. Take the effort as an investment, the return is impressive ;-)
 
I found a nice collection of examples to use python for pen-testing and more.
Found it quite stunning how easy it is with python to build "violent" scripts and learnt a lot reading them.

One good reason to use again the printer :)

Cheat sheets for tcpdump, Wireshark, L2 & L3 protocols, technologies, ... A fantastic resource for netsec admins.

The Grugq - OPSEC: Because jail is for wuftpd

Probably the infosec video of the moment. Presentation targeted to help hackers freedom fighters to not get caught :)

Wow... amazon.com is completely disregarding the initial TCP congestion window: it looks like their servers simply pumping as much data as they can, with an aggressive retransmit timeout as well...

See wireshark capture below: no client ACK's have been sent following the initial GET request for the homepage, and Amazon servers are just pumping bytes: ~76KB outstanding, and growing! 

I guess that's one way to make your site faster... =/

Do you REALLY trust all the CAs that your browser trusts? have you ever checked that list?

It's amazing how powerful nginx is. Do you, as NetSec Engineers or Admins, use nginx as a reverse proxy or as a load balancer? It could be interesting to read someone's opinion on nginx vs commercial solutions as F5 LTM, Alteon, Brocade or the good old Cisco CSS.

Love it! How come no one created this before? And they say you can find anything on the Internet... Not until now! :-)

Story
Introduction
Hello everybody!

Welcome to my G+ profile page. I'm Pedro J. Pérez, a guy from Barcelona that lives in Reading.

My interests are all around technology. Mainly mobile phones, networking, infosec and some coding too :)

I work as a network security administrator but I also do some amateur-ish coding in my free time. So if I have you in my circles there's a 90% of probability that you're a coder or a network admin ;-) or write about one of those topics.

Feel free to browse around all my public information and don't forget to visit my pet projects (links in "Contributor to").
