Heroku 16 Imagemagick Buildpack
Problem I'm working on a project that requires imagemagick to work on the Heroku 16 stack. When using the buildpack, I get the following error: libgvc.so.6: cannot open shared object file: No such file or directory Solution I was able to fix the problem by including the GraphViz buildpack. In order to get Imagemagick working on Heroku-16 you need to add the imagemagick and GraphViz buildpacks to your…
Understading K-Means
K-means is a clustering algorithm used to categorize data that is unlabeled. It is a type of unsupervised learning (data without categories or groups). The goal is simply to find the groups in the data defined by K. The algorithm works by iteratively assigning each data point to one of the K groups based on the features provided. Some of the use cases for K-Means are: Pattern recognition Classification analysis…
Machine and Deep Learning Tools You Should Be Using
I've come across various tools used for machine and deep learning, both good and bad. I decided to write a quick little blog post on some of the tools machine and deep learning you should be using. Tensorflow Tensorflow is an abstraction library that allows you to build machine learning programs with an easy to use API. It was developed by researchers and engineers working on the Google Brain Team.…
Uploading Your Own Datasets to Floydhub
Problem If you are using Floydhub to train your network you might run into the following issue: Directory contains too many files to upload. If you have data files in the current directory, please upload them separately using "floyd data" command and remove them from here.

If this is a child template, ensure assigns are given explicitly by the parent template as they are not automatically forwarded. Available assigns: [:event] My parent template looked something like this: <h1>All Events<…
Getting Started with Gitlab CI: Installing and Configuring Gitlab CI
What is this about? Over the next weeks I will go over how to use Gitlab CI from scratch. I will go over how to install and configure it on your server, run unit and integration tests, build and push Docker images, deploy code, and go over other use cases. I will assume you already use Gitlab as your repo manager since it's required by Gitlab CI. What is Gitlab…
