The most recent Rzeszów Ruby User Group meeting confirmed our belief that it’s worth it to discuss topics other than Ruby even among a Ruby crowd. The organizers saw a 50% increase in attendance compared to previous editions. Participants talked about the advantages and disadvantages of TypeScript, and learned what the role of a DevOps Engineer is and isn’t. Overall, it was a very fruitful meeting.
We’ve had another successful meeting of the Rzeszów Ruby User Group and we’re eager to share our thoughts and impressions! iRonin is the proud sponsor of RRUG. Our developers are active members of the community and enjoy sharing their knowledge through presentations on various Ruby-related topics. This time, they were there to listen to two other speakers, who talked about building apps using hexagonal architecture and about what it means to be a “senior” developer.
Here’s a short tip for all programmers out there: do not push by force to gem repo. Why?

If you’re looking for a Ruby on Rails development team, you likely know RoR’s advantages. It’s a great back-end framework for rapidly developing robust web apps. Thanks to how mature both the community and the technology are, Rails resources (most iconic of which are its libraries, called gems) are stable and trustworthy. Instead of writing a user registration feature from scratch, developers can focus their attention on what makes the project truly unique. And on top of all that, Rails’ testing culture and support are excellent.
Knowing this, what you need next is to find the experts that’ll help you leverage Rails’ strengths.
Do you know what Airbnb, GitHub and Kickstarter have in common? Their websites are built with Ruby on Rails, a well-known and much-loved back-end framework. Though widely used for large-scale projects, Rails offers a particular advantage to startups, as it allows for rapid development and helps shorten time-to-market while maintaining high code quality. Rails is a web framework for the programming language Ruby, which has been around since the mid 1990s and is still popular among developers. Its main rivals in the world of web development are Python and PHP, and in this article, we’d like to take a closer look at the advantages and disadvantages of these three technologies.
Recently, we had an interesting request from one of our clients where we needed to implement time travel for testing purposes - or fake time travel at least! The Quality Assurance (QA) team of one of our clients wanted to test functionality under particular time constraints within their application. To do that, they needed is to move the application’s internal clock to check and see whether some these time-based actions were allowed or forbidden (depending on the case). Mocking up operating system’s datetime settings on Heroku was the answer, with setting up environmental variables for datetime testing. Heroku datetime testing in a Ruby on Rails application required a little configuration - but we were able to get the job done.

When you work on a project that’s been around for quite a while, you’re probably going to - sooner or later - encounter a few skeletons in the closet. These skeletons might be sections of code or design patterns that people know about, know they are bad, and yet no one is addressing them for various reasons. Probably because nobody wants to do the redesign if the code just “works” - even if it’s terrible. What’s worse is when these same structures or patterns are being repeated, because people are blindly following them!

Working correctly with database indexes is always the key to application performance and reliability. Especially when the amount of data grows rapidly, well designed database architecture really pays off. However, when we’re working with database indexes, it can be easy to miss something, or fall into the trap of a tricky outlying case. One of these is when performing unique indexing on multiple columns, where at least one of them is null.
