Configure Frontend Projects with Dotenv

by László Csele `Lacka` / April 4, 2019

Handling secure data (such as API keys) in any project’s repository is a crucial part. In previous years, I came across many approaches to resolve this issue. Some of them did a pretty great job, but others didn’t resolve it at all. 

In this post, I’ll show you step-by-step how to configure frontend projects using dotenv with .env file, dotenv and convict npm packages. This configuration works with any frontend app that use webpack to bundle the application.

Case Study: GPU Orchestration Using Docker

by Péter Esztári / March 6, 2019

GPUs are getting more and more memory and compute capability nowadays. This is super good news if you are using them for HPC (high-performance computing), but some workloads may only require a fraction of a card. This is the point when GPU orchestration comes in the picture.
Top Signs You Need a Non-Relational Database

by Oren Eini / February 7, 2019

Today’s data is coming in at speeds and substances we’ve never before seen. Systems designed during the days of disco are being used to handle petabytes of information in real time.

When you’re looking to build an MVP and later a production mobile app as a small team, the task at hand may seem daunting. You’ll obviously want to focus on the actual mobile app design and the UI, which by itself is no small feat. On top of that, you’ll need to figure out how to develop and release the app for both iOS and Android platforms. This is exactly the situation I faced as a solo-founder and developer of DealCheck – a cross-platform app that helps real estate investors analyze potential properties to buy.

5+ Reasons to Use Selenium with Docker for Application Testing

by Suraj Vijayaraghavan / September 13, 2018

Application testing is a key element to make sure your web applications run smoothly, as it tells you whether the tested scenario works without a hitch and the features run as validated. High test coverage, code reviews and pull requests are required for a fast pace and high-quality code. Docker gives you the best of this because you can run your tests in containers or isolate them in development and deployment.
