Weeks ago while working on the @Covid19AO_Stats bot I ran into a problem related to the way Python processes text.
What helped understand what was happening was the presentation below.
For some time I have been trying to learn Python, a programming language that is easy to use and the preferred one for many network engineers taking the first steps on automation. I read some books, watch some youtube videos and create some dumb scripts. But what really helps is creating a project, however small it is and doing it from start to finish. So, I decided to build a twitter bot.Continue reading →
As I was writing another post I realized it’s been a while since a 2 year old could count he number of CCIEs in my country.
Jeriel Atienza and André Malungo were for a long time the only Angolan CCIEs, but today the numbers are quite different.
I recently had a small change in my life which required me to spend more time on the road. It is not the best of places to be and it “eats” a lot of time of our days which could be much more productive.
I am leaving some tips here for app which help not to throw that time away and learn a few things while you are driving.
Have you read the news? No?
Cisco just updated their certification program. The CCNA, CCNP and CCIE certifications. All tracks!
This is the first in a series of posts where I will be doing a brief summary of these changes and try and guide everyone in the middle of their journey to become Cisco certified.Continue reading →
In March 2014 I was a team lead for a small networking team in an Angolan ISP. After 5 years contributing the best I could to get the company of it’s feet, the time was coming for the progression many wished in their professional careers. I was invited to be the head of IT. Niiice!!! Continue reading →
The interest in cloud computing has been growing inside me for quite a while. Its advantages, how it works and the technologies involved.
In the middle of all this I found a very interesting document that I saved from being eaten by my son. I was lucky to arrive on time.
Demystifying the Cloud helps us understand the history and the path taken to where we are today, virtualization, the essential characteristics of the cloud and in the end quickly describes the top 3 cloud computing providers. While it was written in 2012 and I already knew parts of it, it was still relevant to remind me of the concepts and strengthen my little knowledge.

From very early in my networking career I have been fascinated by protocol details, packet captures and the features of my top 3 application troubleshooting tool: Wireshark.
Getting the captures on the endpoints (clients/servers) is relatively easy but things can get difficult when you want to capture traffic somewhere in between and is hard to do port mirroring (SPAN) on some remote switch.
Packet Capture Capabilities of Cisco Routers and Switches is an old video (4 years is old right?) posted on the Cisco Support Forums that highlights different methods to get on box packet captures in Wireshark .pcap format or in text output.
