In this article we will see how Vaadin UIs can be written using Python. We'll use Jython which implies Python 2.7. GraalVM will be considered in a later article.
First download a server side starter from vaadin.com or any other place. We won't be using client side templates, but build UIs purely using code. Next

#How you get Sail.js running on Openshift#
This instruction is tested with:
###1) package.json
If you use the package.json build by sails new Projectname than you have to add a few fields for openshift – so the server can start you app automatically. Sails uses Grunt to build minify css/js and so on. Openshift dont have grunt installed so you have to add this also.

One of the most commonly overlooked and under-refined elements of a website is its pagination controls. In many cases, these are treated as an afterthought. I rarely come across a website that has decent pagination, and it always makes me wonder why so few manage to get it right. After all, I'd say that pagination is pretty easy to get right. Alas, that doesn't seem the case, so after encouragement from Chris Messina on Flickr I decided to write my Pagination 101, hopefully it'll give you some clues as to what makes good pagination.
Before going into analyzing good and bad pagination, I want to explain just what I consider to be pagination: Pagination is any kind of control system that lets the user browse through pages of search results, archives, or any other kind of continued content. Search results are the o
