Blog redesign
It’s been a while since I worked on the blog’s design. The design dated back to 2011 which is like an eon in Internet time and I didn’t particularly liked how it looked anymore so I decided to change it.
I normally don’t do any design work and CSS is not something I’ve enjoyed particularly but I’ve always used this space to work on that area.
Packaging AWS Lambda dependencies using docker
Recently I’ve been using AWS Lambda at work for some projects and one of the limitations that you have is trying to use packages with compiled dependencies.
Compiling them on your machine won’t work and the “recommended” way is to start an EC2 instance and compile your dependencies there and then copy those to your machine back.
Fortunately AWS now provides a docker image for amazon linux which we can leverage to build our depencies. We can avoid launching an instance and get faster results.
Using docker containers with your existing rails app
This tutorial is an extraction from a talk I recently presented about docker and rails apps at the Barcelona on Rails user group. I’ll explain how to integrate docker into an existing rails app workflow.
Faster docker containers development using fig
Yesterday I had the opportunity to present a lightning talk on the Barcelona Docker Group about working with fig.
During the talk I presented a tool that is helping me focus on developing the different containers and make the changes to the Dockerfile and the apps themselves and leave out the details of using fig.
The tool is called guard-fig.
Changing to devops
It’s been over 3 months since my change to the site operations team at Xing and time has really been flying by.
Everything is new and I really don’t know what to do many times and that I find very delightful. The investigation, learning, figuring out how to achieve something, reading forums or stack overflow and trying to fit a puzzle into your head. I think this is what I love the most about computers, that moment when you understand the machine, what it does and why it does it. It’s the hack, making the computer do what you want. Getting out of my comfort zone is helping me appreciate the basics more.
