Using Datadog to optimize ActiveRecord performance

That’s a fun question, but not nearly as useful as, “what’s effective?” Pick up a fifteen-year-old copy of Wired, or a business book from 1969 and see what’s still aro…

Linux offers a lot of commands to help users gather information about their host operating system: listing files or directories to check attributes; querying to see what packages are installed, processes are running, and services start at boot; or learning about the system's hardware. Each command uses its own output format to list this information. You need to use tools like grep, sed, and awk to filter the results to find specific information. Also, a lot of this information changes frequently, leading to changes in the system's state.

How to document a Socket.IO API? This is the first part of a series of blog posts covering the modelling of the Socket.IO protocol using AsyncAPI objects followed by a step-by-step tutorial on how to create a specification YAML file given an existing Socket.IO API.

REST is the ubiquitous way of writing APIs for as long as I can remember. Today I want to introduce you to a new way of writing APIs. Have you met gRPC? gRPC is a relatively new way to write APIs and consume them as if you're just calling a functio...

In the previous post, I’ve shared a few things that were useful to me as a developer. Now wearing my “ops” hat, there are a few things that I wanted to cover - blocking bad clients, rate limiting, caching, and gradual rollout. Blocking bad clients Blocking bad clients in nginx is usually implemented with a simple return 403 for some requests. To classify request we can use any builtin variable, e.
