A month ago I stumbled upon a problem: I wasn’t able to find a Ruby gem which would do in-memory caching with the capability to expire on timeout. After some quick research I decided to implement my own and called it Zache (as in “zero cache,” since there is no back end). Here is how it works: First, you create ...

When it comes to testing email templates for production; I think it is fair to say testing is key. Action Mailer is one of the most recognized frameworks for sending out emails. With Action Mailer you can send out emails through different providers easily, preview templates, and so forth. (Although from my work experience, I have always found it extremely ...

No offense, but this is what I’ve figured out after dealing with Ruby code and speaking with Ruby programmers over the last half a year.

Sorry if that title seemed stupid. The super serious title would be “Creating a REST API in Rust using Rocket and Diesel”, but that’s boring. Anyway… Here I go with my first post that fully focuses on Rust. After spending a few months doing a bit here and there I decided to just dive right in as I was going ...

With genetic algorithms (GA), you can solve optimization problems using the same concepts that you find in nature: Reproduction Survival of the fittest Adaptation to the environment So what’s an optimization problem? It’s when you want to find not just a valid ...

Next up in Rust for Java Devs we have structs. They are used to hold data within a logical unit that can be passed to other functions or execute their own methods on the values that they store.
