How to obtain a Civica metro card in Medellin, Colombia

April 13, 2015

Medellin has a very modern metro system, but one of the things you'll notice when you first use it is the long line at the ticket window. For some reason, the stations don't have ticket machines.

If you use the metro a lot, it's very much worth the effort to get a Civica card. It will save you a lot of time in the long run plus you get around 10% off ...

Django 1.8 Project Template

April 12, 2015

Yup, that's right, another Django project template!

I know there's a ton of these projects already on GitHub, but as I was in the process of rewriting an old Django project last week, I found out that Django 1.8 just came out. I figured this is a good opportunity to create another one I could use for future projects as I already have a few small ones in mind. Django 1.8 ...

A day trip to Guatape, Colombia

Solr request returning a 400 (Bad Request) response

March 26, 2015

I was troubleshooting an issue for a client the other day where certain Solr requests were returning a 400 (Bad Request) error response. There were actually 2 separate issues:

2. The Solr query parameter contains too many boolean clauses (the error actually says 'too many ...

Installing hub (git wrapper) on Ubuntu the easy way

February 26, 2015

This is more a "note to self" in case I need to do this again.

We use hub at work mainly to convert GitHub issues to pull requests. For Mac users, you can install it by simply typing in brew install hub. But for Linux users, the installation is a little bit more complicated (below is the easy way to do it without needing to install Ruby):

sudo curl https://hub.github.com/standalone -Lo ...

Notes from 'Antifragile'

February 16, 2015

I read Nassim Nicolas Taleb's latest book, Antifragile: Things That Gain from Disorder, a few months ago and it easily became one of my favorite books. I liked the way he explained things and he covered many topics that are very relevant today. I'm actually re-reading parts of it right now. I figured I'll take this time to share my notes in a blog post.
