Operability.io - Day two

 Posted on September 25, 2015  |  Alejandro Guirao

The second and last day of operability.io has been packed of interesting talks. In the following paragraphs I’ll pick some details about each talk. Charity Majors (@mipsytipsy) has talked about Building a World Class Ops Teams. Very valuable thoughts as: If you are a startup, you need an ops team only if you need extreme reliability, scalability, security or you are tackling with operational category problems for the whole internet. Otherwise, stick with your lean dev team. [Read More]

Operability.io - Day one

 Posted on September 24, 2015  |  Alejandro Guirao

Today I’ve been attending operability.io, a conference about DevOps but focusing on the Ops part of the term. The conference has only one track and the speakers are hand-picked, seriously cool speakers chosen by the organization. In general terms, I have found that the talks have been about philosophical or psychological aspects of DevOps and not about technical aspects. I get that probably this is the leitmotiv of this conference (principles over tools, and so), but code and demos definitely beat slides with pics and cool sentences :-) [Read More]

A Dockerized GeoToad for paperless Geocaching

 Posted on August 15, 2015  |  Alejandro Guirao

In the recent years the game of Geocaching has steadily grown in popularity as a hobby and outdoor activity. Basically, Geocaching consists on a worldwide-played game in which people hide caches (containers with at least a paper log) and publish their coordinates over the internet so that other players can find them and log them. It is very addictive, believe me. There are many applications to play Geocaching with a smartphone, being probably the most famous c:geo. [Read More]

Introduction to Autotools

 Posted on July 29, 2015  |  Alejandro Guirao

Recently I have discovered the Autotools suite for compiling/packaging C applications. I have played with it a little bit, following the examples and hints from this book, and I have found that it is an incredibly useful toolkit. I am going to describe an example of how a tiny C command-line application can be packaged and delivered using Autotools. I will also include a dynamic library in order to make it more realistic.

Discovering PlatformIO

 Posted on June 2, 2015  |  Alejandro Guirao

The RaspberryPi / Arduino combo kit is a winner option when prototyping an IoT-style project. The Raspberry Pi, as a cheap, low-powered, full-blown Linux machine, can interact with other systems via network connectivity and harness the power of high-level languages and abstractions, whereas it can offload the duty of interfacing the circuitry to the Arduino, which is in turn best suited for this tasks. The Arduino board can efficiently read analog signals, has better voltage/current protection and can take advantage of the myriad of shields and modules available in the market to expand its functionality.

Hi!

This is my Hello World! post.

I’m testing the features of Nikola as a static site builder. Looks nice :-)
