Identifying bottlenecks and optimizing performance in a Python codebase

July 08, 2019 In this post, we will walk through various techniques that can be used to identify the performance bottlenecks in your python codebase and optimize them. The term "optimization" can apply to a broad level of metrics. But two general metrics of most interest are; CPU performance (execution time) and memory footprint. For this post, you can think of an optimized code as the one which is either able to run faster or use lesser memory or both. There are no hard and fast rules.

Prometheus and Docker: Monitoring Your Environment

Coming back from Monitorama, I had a chance to sit back and start playing with some tools to see how they worked. Prometheus is a pretty ubiquitous tool in the monitoring space, it's pretty easy to spin up, and is open-source. Having a very active community of engaged developers means finding help articles or guides is easy. We are also going to use Grafana to build nicer looking graphs based on API queries from Prometheus.

Debugging with Rails Logger

If you’re a Rails developer, then you’ve probably used Rails Logger on at least one occasion or another. Or maybe you have used it without even realizing, like when you run ‘rails server’ and it prints information to the terminal window, for example.
