Node.js and Postgres

This tutorial shows how to create a simple web server with a tiny REST “API” and a PostgreSQL database. I asume that you have installed the node.js platform and npm.

TypeScript and jQuery

Markdown ist eine einfache Auszeichnungssprache, welche sich vor allem in der Welt der Softwareentwickler verbreitet hat. Was mir bei der Kombination Ghost + Markdown gefehlt hat, war eine einfache Methode Syntax Highlightning einzubinden. Doch diese Funktionalität lässt sich ohne großen Aufwand nachrüsten. Es gibt einige Möglichkeiten…ich habe mich für prism. Continue reading

Phonegap / Cordova 4.x app with Android Studio 1.x

I assume that you have a working installation of PhoneGap or Cordova CLI. In this post I use the Cordova CLI which is distributed as an npm package in a ready-to-use format (npm install -g cordova). Continue reading
