I wrote some time ago about thread-safety in OOP and how it can be achieved with decorators. It was also said that it’s very important to make sure objects are thread-safe (in Ruby and in Java), especially in web apps, which are multi-threaded (well, in most cases anyway). Well, here is SyncEm, a primitive Ruby gem which makes the above ...

When it comes to testing suites, it’s imperative to have a strong suite with all the tools to make your teams life easier. Once your team has a strong testing suite, automating the suite with continuous integration (CI) will bring less defects in your production environments. Currently, the industry has some best practices for testing: BDD, TDD, etc. – although ...

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 ...

Are you a Ruby developer? If you are, I’m pretty sure you have a very vague idea of what concurrency and thread safety are. 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. I’ve been writing in Ruby pretty actively recently and I do ...

In the software and technology of today we see information in text form everywhere. Text that isn’t given to us in media formats such as images and videos are all stored internally in the computer as numbers with the encoding as the means we have to interpret how they should be read properly. This becomes much more evident when sharing ...

Performance is a topic many developers value highly, with web frameworks, programming languages, databases, and various technologies all boasting about performance. However, this isn’t usually the first consideration for a web application, as getting a product or service made more quickly is a higher priority. We tend to think about performance once a product/service is in working order and we ...

You know what OAuth login is, right? It’s when your users click “login” and get redirected to Facebook, Twitter, Google, or some other website which then identifies them. Then they go back to your website and you know who they are. It’s very convenient for them. It’s convenient for you too, since you don’t need to implement the login functionality ...

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 ...
