letsencrypt.org is the new awesomeness that happened to SSL on the web. Forget over-priced trusted certificates or self-signed certs for your side & pro bono projects. Try trusted SSL in seconds for free instead :). If you choose to use Let’s Encrypt I want to show you what needs to be done on a pretty […]
From the start I wanted an unobstructive and flexible API for InvoicePrinter. This flexibility enables anyone to make international duo-lingual invoices without any special i18n API provided. But the truth is I had something a bit better in mind from the beginning and in 0.0.9 I am including something new suited for the job.
Chances are you might need to run wkhtmltopdf on your server or in Vagrant environment (e.g. to overcome compatibility issue such as Cannot mix incompatible Qt library (version 0x50700) with this library (version 0x50701)). That way you need to be able to run it without an actual X server.
At work I needed to accept a Windows-1250 encoding in URL parameters on some actions in one of our Rails API endpoint. The problem is that Rails will scream at you since everything needs to come as UTF-8. Future! Unfortunately some 3rd party Windows software might be still in the past… at that time I […]
Let’s have a quick look on how to reuse our Ruby code and gems in Java leveraging the awesome work of JRuby guys. What we need is Java, Gradle and JRuby installed and we are ready to rock.
HTML-to-PDF or Prawn? Let’s look how these compare by generating an invoice using PDFKit and InvoicePrinter and examine performance, memory and usability.
Ruby on Rails come with three environments by default – development, testing and production. But sooner or later one has a need for staging environment. And don’t get me wrong, you can (or should?) use the production settings there, but if you run it locally or on the same server as production, chances are you […]
This is a little thought on packaged Ruby versions (mostly in Linux-based systems) and why I don’t get many people advising newcomers to start by installing RVM when in reality they just want to program Ruby.
They are many options how to generate PDF versions of your invoices in Ruby and the ones that do not come with system dependencies are often built on top of Prawn library. InvoicePrinter is no different. Here is a short announcement on what it is (and aims to be) and what not.
When I firstly heard about Crystal language, I got really exited. It fixes exactly four problems I sometimes have with Ruby; types, speed, memory consumption and compilation to machine code. After many months silently following its development I decided to try it out for a simple program I need — a simple server standing between […]
