Let’s say you are building a git analytics product. Your product supports GitHub and GitLab for now. It might support more products in the future. 90% of the codebase that supports GitHub and GitLab is identical. 10% is specific to GitHub and GitLab. There are two ways to build software abstractions here. The easy path to fall for is to have unified objects that take care of both GitHub and GitLab data. These objects would, however, behave 10% differently depending on whether it is GitHub or GitLab. Your codebase will be ridden with conditionals that trigger only for one or the other. ...

If you run any web service always enable support for serving compressed responses. It will save egress bandwidth costs for you. And, more importantly, for your users. Over time, the servers as well as client devices have become more powerful, so, compressing/decompressing data on the fly is cheap.

Hugging Face is GitHub for machine learning models. Their on-the-fly model download scheme, however, is difficult from a DevOps perspective. Here’s how to disable it.

Every public-facing API service should have API usage limits. If this seems overkill then ask yourself if would it be OK if a single IP sends a million requests a second. This does not apply just to publicly documented services but even to undocumented services that are publicly accessible.

Just like me, they think that Toast must be displayed from the UI thread. Even though there is no reason. ...

There are several ways to deploy Docker images on Microsoft Azure. My favorite one is Azure App Service/Web Application for Containers. This is the closest to Google Cloud Run.

Google released a new version of the Google Auth library. It had a bug that broke Google Login on Android for API 26 and earlier. This impacted my small but popular Music Player app in Google Play. It reveals the kind of problem, I have alluded to in end-to-end testing. The only way to avoid such problems is by end-to-end testing. However, I find all Android testing frameworks to be terrible. ...
