Working on inherited code bases
Serverless Node apps on AWS Lambda
Five UX tips for improving forms on mobile apps
If you are a freelance developer or working for a project / consultancy company like us here at reinteractive, there is a good chance you'll be working on inherited codebases that were created by other developers/agencies. Unlike greenfield projects, existing codebases come with uncertainty and a lack of background knowledge that you normally get from a project created by you or your own company.
To make this situation even more challenging, these projects usually come with tight deadlines so there is limited time for you to fully understand the codebase.
To many of us, our cars, motorcycles and push bikes are critical to our day-to-day operation. Even if we don't use a car regularly, the taxi, bus, train or ferry network we use to commute is critical to our day to day living.
What would you think if you found out the car you were driving has not had a checkup, or at least an oil change in the last couple of years? Would you ignore your mechanic, or would you take your car in, for at least a rudimentary checkup when needed?
Whether you are a veteran Ruby on Rails developer or relatively new, the rapid application development framework that is Rails focuses on quickly getting things up and running. Sooner or later it's likely that your speed of development has made a great product, but the speed leaves a bit to be desired - and your code needs optimisation.
But now you need to know what to optimise.
At reinteractive we have recently completed a project calling for us to use OCR (Optical Character Recognition) technology to recognise printed text from photographs. It's a fun problem to solve, and so here is a brief post on how you can also set up your Rails app with OCR capabilities.
Tesseract is one of the most popular OCR libraries. It's free and open source, runs on multiple platforms, supports a lot of languages, and its ongoing development is sponsored by Google. It is primarily a command line tool (although there are third-party projects that supply a GUI), and, luckily for us, there are a couple of Ruby gems out there allowing us to interact with it from a Ruby/Rails app. For this post, we will use https://github.com/meh/ruby-tesseract-ocr.
