Explorations - computing, research, etc.

My article on getting started with gRPC in Python is up on the codeship blog: Using gRPC in Python I build upon it in the next article: Exploring Security, Metrics, and Error-handling with gRPC in Python The demos can be found in the python-grpc-demo repo…

consul allows a service to associate itself with tags.

Problem Let’s say a program in a container should be able to resolve a custom hostname.

Problem Let’s say a program in a container wants to communicate with a service running in another docker container on the same host.

I recently wrote two articles on Python application monitoring with Prometheus: Monitoring Your Synchronous Python Web Applications Using Prometheus Monitoring Your Asynchronous Python Web Applications Using Prometheus The demos can be found in the python…

Distributed tracing is the idea of tracing a network request as it travels through your services, as it would be in a microservices based architecture.

gitbackup is a tool to backup your git repositories from GitHub and GitLab.

This guide will be how I usually setup and get started with Go development environment on Linux.

Using QueueLogger with Python JSON Logger When logging from multiple processes (via multiprocessing module), using QueueHandler is one approach with Python 2.

This guide will be how I usually setup and get started with Go development environment on Linux.

I presented at the PyCon 2016 Education Summit on "Doing Math with Python" day before yesterday and a lightning talk yesterday.

My article "Write a program to tee output using Rust" is out in Linux Voice (Issue 27).

In this post, I will post my notes on how I got runC and then using libcontainer on Fedora.

My article "Write an Image Cropping with Go" is out in Linux Voice (Issue 26).

Update: Changed the Koji URL to reflect the change to livemedia As the Fedora Scientific maintainer, I have to make sure I look into whether the nightly build is failing so that I can look into the why.

Let's say you have some Python application code which connects to Amazon S3 which retrieves the keys in a bucket.

In Python, when you need to create a temporary file with a filename associated to it on disk, NamedTemporaryFile function in the tempfile module is the goto function.

Updated: Fixed typo in the last paragraph.

In this post, we shall take a look at the idea of data only containers - containers whose sole purpose is to exist on the docker host so that other containers can have portable access to a persistent data volume.

I have until the last few months (of my ~4 years of working with Python) always worked without virtualenv for all my Python projects.

Recently at work, I wanted to test a string which was being created by the urllib.urlencode() function.

My workflow with docker usually involves volume mounting a host directory so that I can read and write to the host directory from my container as a non-root user.

My goal in this post is to show how to setup puppet in standalone mode on a Fedora 23 system.

Fedora 22 was released recently which also means we have a new Fedora Scientific release.

I changed the mapping of my domain to point to my GitHub pages.
