Existen ocasiones en las que requerimos que el contenido de una rama esté disponible en otra, sin realizar un merge, ya que esto implicaría arrastrar otras partes del historial. Esto se logra mediante el uso de cherrypick y, para simplificar la tarea, comenzamos realizando un squash. A continuación la receta:

As I’m building a new startup I’ve been installing several Macbooks and helping engineers on their own setup, of course, we all have our kinks on configuring our machines but there is a base that would be nice to share and keep as standard as possible. Those are my (hopefully sane) defaults.

Compartimos nuestra experiencia migrando de 100+ VMs a un cluster de Docker Swarm, los componentes y prácticas que brindaron estabilidad, control y cuales son nuestro planes futuros basado en ese aprendizaje.

If you never heard about Jupyter Notebook, I highly recommend you to check it out. It have been my primary platform to build reports and data driven case studies. On this post I’d like to show how I create a simple and isolated environment with a Bash script and Docker to run JupyterLab. Recently Jupyter Notebook received a major overhauling and become JupyterLab - currently in beta, but the new platform looks fresh and very powerful.

Recently we had to move a full Cassandra backup to another cluster of machines (another Datacenter on Cassandra’s jargon). Although it can be achieved using DC replication we opted for a more conservative approach and not change production configurations neither increase its load due data streaming. This post is quick comparison to find out which tool would perform better for copying a large directory tree locally. ## The Data One of our Cassandra’s clusters contains 12 nodes, each node has 532Gb of data distributed among 1,753,200 files (the /var/lib/cassandra folder).

La última semana tuve la oportunidad de contar la experiencia de Socialmetrix instalando y configurando clusters de Datastax Analytics en Azure. Datastax brinda una solución comercial en un bundle, conteniendo Cassandra, Spark y Solr integrados. Las charlas se dieron en Argentina Big Data Meetup. Hosted by Jampp y el Nardoz Meetup. Hosted by Medallia

We run several processes that may take hours to complete and it is nice to be notified on a Slack channel when those processes finishes correctly. Using the Slack’s Incoming Webhooks API, a small bash script and a couple of tricks it is really simple!
