Last Friday, I passed my CCNA exam.

CCNA certification

I would like to thank GNS3‘s developers and community for their great work.


Learning Scheme

Filed under: Studies — acidborg @ 21:53

I’m learning Scheme because it’s the programming language chosen for my subject on Machine learning.

It’s a bit difficult to change the way you think and program when you are used to other programming languages like C or Python, but thanks to my prior knowledge of Haskell, I’m finishing all the exercises on time.

If anyone is interested in learning Scheme, here is the quick introduction I’m using: Teach Yourself Scheme in Fixnum Days.


Studies upgrade

Filed under: Studies — acidborg @ 10:32

After my holidays in Ireland, I finally found some time to post on my forgotten blog.

I finished the “Master in advanced networking and multimedia contents” (in Spanish) and next month I’m starting a PhD in Artificial Intelligence (in Spanish). I’m very excited about it, although I know it will be a hard task to achieve.

Next week, I’m reviewing all my IA university notes and maybe some courses from MIT’s OpenCourseware.


Many changes

Filed under: Free Software, GNOME, Python, Studies, SysAdmin — acidborg @ 19:46

Much time without blogging (since May, 18th). Many changes in my life left me no spare time to blog, so I’ll try to sum them up:

  • University: I finished my degree in Computer Science Engineering (“Ingeniero en Inform├ítica” in Spanish). I got quite good marks, specially in the final project for my major about IPv6 deployment. I want to go on studying, so I’m starting a Master in advanced networking and multimedia contents on October at the UNED.
  • Work: I started working as a GNU/Linux sysadmin on July. I have already set up a Nagios monitoring system and I’m planning to do some clustering stuff at work.
  • WhyFLOSS conference (Madrid): I gave a lecture on IPv6 deployment both using a tunnel and a Dual stack approach. You can get the PDF file here (in Spanish)
  • Conduit: I’ve coded some patches [ 1 , 2 ] to add initial N800 sync support to Conduit. It just syncs N800’s backup files, but support for music and video files is coming.


My first IPv6 talk

Filed under: Studies, SysAdmin — acidborg @ 21:00

Today, we had a meeting with the University’s Data Center staff.

First, I gave a talk about IPv6 and I showed them our plan about IPv6 deployment on the University’s network. It was my first talk outside the faculty and it turned out to be better than I expected. Then, my friend Alberto showed them our simulation of the University’s network using VNUML, a network simulation program based on User-Mode Linux.

They seemed quite interested in both the idea of IPv6 deployment and our simulation, so they asked us some interesting questions about them. As always, money and time are the main difficulties in this kind of deployments, so they told us that, before starting, they have to estimate how much money it would cost (due to the new hardware required) and how much money the University can afford to spend on it. They also tell us that this won’t be done before Summer due to some priority projects.

Although these last two things could sound discouraging, they asked us some questions that we didn’t expect to hear, like how far we had planned to go with our project, what were our next steps and whether we will be willing to explain them more advanced concepts about IPv6 and about our simulation and how to use it after the Summer. We agreed to keep in touch and see what comes next.

To sum up, I’m very happy with the result of the meeting ­čśÇ


Writing, writing

Filed under: Studies — acidborg @ 22:16

I’ve already started writing the report of the Final Project for my major.

I’ve almost complete the IPv6 theory chapter and I’ll soon start writing the chapter about my University’s network case study.

In two weeks time, we’ll have a meeting with my University’s Data Center to show them our work and our plans for IPv6 deployment on the University’s network.

Let’s see whether they are interested or not…


Back to the daily routine

Filed under: Studies — acidborg @ 00:07

I’m back from my Easter holidays. I spent a wonderful week in Santiago de Compostela and I took a break which I needed indeed.

Today I’ve returned to the daily routine (study, programming practicals and start writing the report for the final project for my major). I look forward to finishing my degree…


Simulated mail server

Filed under: Studies, SysAdmin — acidborg @ 01:49

Today, I finished configuring both a SMTP server with Postfix and a POP3 server with Courier for a network simulation.

I had some problems with authentication, mainly using Courier, but finally I managed to solve them. Although it wasn’t a trivial task, it wasn’t as difficult as I had expected.

I just have to configure a simple firewall using IPtables to finish the basic dual IPv4/IPv6 network simulation.

I would like to thank my friend Ma├▒o for his Apache configuration file and his answers to my IPtables questions about HTTP and HTTPS filtering.


What to do after the degree

Filed under: Studies — acidborg @ 22:08

I’ve been talking this week with one of my lecturers about what to do after I finish my degree in Computer Science Engineering (I don’t know whether this is the right name for my degree in English, in Spanish it is called “Ingeniero en Inform├ítica”). He has advised me to do the PhD, but only if I want to stay at the faculty as a teacher, because in Spain the PhD is not appreciated outside the university.

So, the problem is that I don’t know yet whether I want to stay at the faculty as a teacher or not. I been thinking about working for a year or two in a Free Software firm and decide then. Meanwhile, I could improve my English a bit and my German, which I have neglected more than I should.

Any advice or suggestion will be welcomed. Thanks in advance ­čÖé


Hacker culture

Filed under: Free Software, Studies — acidborg @ 23:49

Although it can sound weird (not for me, but for the rest of my classmates), a seminar about hacker culture, free software, software patents and related topics has started at the faculty.

In the first classes, we’ve been talking about hacker culture and we were told to read the article “How to become a hacker” by Eric S. Raymond. I had already read it, but it was funny to read it again, specially if you are told to read it at the faculty!

I hope this seminar will continue with the same approach, because I love this kind of topics and the way they are discussed so far.
