Consider a client (e.g., a messaging mobile app) that interacts with a service (e.g., the corresponding messaging service).
We have three options to test this client.
Recently, I upgraded to R 4.0.1. To avoid broken packages, I started updating installed packages using
install.packages(). This solution was less than ideal because, if a dependee package was not built for R 4.0.1, then the dependent package failed to build and install.
These books cover design trade-offs to consider when scaling systems, the cost and benefits of each design choice, and how current technologies embrace and influence these design choices. They do so while being focused on practice.
Books 1 and 2 are more high-level and cover aspects relevant when designing and…
Recently, while writing an article about logging in Python, I started identifying artifacts and actions that we commonly use when we talk about logging. Here’s what I came up with.
When we use a logging library, we perform/trigger the following common tasks while using the associated concepts (highlighted in bold).
Recently, while reading about MPI, I stumbled on the mpi4py library that brings MPI to Python. Given my past familiarity with Python’s multiprocessing module, I was curious how would the performance of MPI compare the performance of multiprocessing module. So, I performed a small experiment.
Since mpi4py is based on…
In object-oriented languages like Java, C#, or Kotlin, given a type
T, an associated view type
TView is used to expose a specific view (parts) of an object of type
T. This helps hide implementation details.
For example, in the following Kotlin example,
Ledger interface is used to provide access…
This is the sixth and final post in a series of posts exploring web services related technologies. It documents the observations about custom web clients that were implemented in Elixir, Go, and Kotlin and used to evaluate web service technologies.
On the topic of “excellence as a core strategy”, the book does a great job of providing great insights and quite a bit of food for thought and practice.
As for presentation style, it uses a style almost identical to that of “The Little Big Things” by Tom Peters. While…
