Running io.js builds on travis

Update: As Keith pointed out, Travis rolled out a newer version of NVM just some days ago. Having that in place it's actually super easy to get started: node_js: - "0.10" - iojs-v1.1.0 That's it :) And while you can now go and add the lovely supporter badge to your projects, I will try to find out how to not miss those changes from Travis anymore... (Do they have a changelog?) Original post: With the release of io.js 1.0 many Node.JS developers were asking for respective b

Even more contentful ruby apps

Some weeks ago I posted about kickstarting a ruby application with Contentful as its data backend. Now that I gained some field experience with that setup, it made some caveats pretty obvious. This blog post will show you some improvements and also some nicites we added to our app in the last weeks. We found out that the previously suggested approach had three major issues, which get addressed in this post: The configuration was in the model. The models weren't clearly namespaced. The mode

Chasm - Preview

When I thought about plans for the weekend, I had in mind to fix some Sequelize CLI issues and to extend one of my personal projects I'm currently working on. This has been until I opened this one lovely email with the subject "Project Update #37: Chasm by Discord Games LLC". The first sentence read "Anyone who backed at $25+ can play the Alpha build right now!", which made me instantly stop everything I was doing and forced me to open the Humble Key Resender. After recei

Farewell make ... Hello gulp ...

At work, we recently decided to switch our JavaScript coding style from a chaotic mess to a more consistant, disciplined and streamlined masterpiece. In order to achieve that goal, we decided to include JSHint in our build process and to configure it as strict as possible. As our codebase is relatively young, it was quite easy to get things green and to make the linter happy. Inspired by this move and by the consistent code style that followed, I thought about making the Sequelize CLI compatible

Contentful ruby apps

Lately I was playing with the content management service Contentful and its ruby gem contentful.rb. In this article you will learn how to kickstart your … contentful … ruby application! Contentful is a cloud-based and API-driven content management system that allows the user to structure his data via so-called content models. Those models are the blueprint for the to-be-stored information. One could think of them as database tables which have specific schemata. Once defined the user can create

Cubi - details about my entry

It’s been a long time since my last post… However, I haven’t been lazy, but worked on multiple things over the last few month.

Changes in Sequelize 1.3.0

Sequelize v1.3.0 was just released and comes with some funky new features and some minor refactorings, which you should know about. Most important things are: Migrations, validations, cross-database support and new event-listener notation. Model#all is now a function and not a getter In earlier versions it was possible to get all entries of a model with the following command: User.all.success(function(users){}) This has changed and the all-getter was refactored to be a function. This way it is

Hi! For now it is not possible to add a special data type. But you could use the boolean datatype for the ‘sex’-attribute and add a gender method which evaluates the attribute and returns ‘male’ or ‘female’ as value. Take a look at http://sequelizejs.com/?active=expanding-models#expanding-models and http://sequelizejs.com/?active=data-types#data-types for further information. What do you think?

Changes in Sequelize 1.2.1

This post summarizes changes in Sequelize v1.2.1. It is highly recommended to read this post due to some changes in default values and interfaces. There are also some minor, but very cool new features. Global options for models In Sequelize v1.2.1 I’ve refactored the not so officially communicated possibility to define Sequelize-wide options, which are passed to the Models in multiple cases. I will explain the usage in the following, for now let’s see how it was before and how it has changed: v

Theme Hospital on Mac OS X with Boxer 1.1.1

Hey Mac gamers, about an year ago I wrote an article about, how to get Theme Hospital work on Mac OS X. Because that post is very old and things have changed, here is an updated how-to. Install Boxer. Move the extracted file to the Applications folder. Get a copy of the game. I just used a copy (ISO file) of my old cd. Open Boxer. Choose “Import a new game”. Throw the ISO file / disk drive from the Finder into the wizard, saying “Drop your game here.” Choose setup.exe (was default for me). Sele

[sdepold] Sharing Rubymine preferences via Dropbox

The naive way When thinking about sharing stuff on multiple devices, you will stumble across Dropbox. The first and obvious way is movingyour preferences folder into it and symlinking it into the origin place: mv ~

Creating spaces in the Mac OS X dock

Creating spaces in the Mac OS X dock This video shows a way to add spaces to the Mac OS X dock. This is great if you want to group programs. For example you could seperate multiple folders into a specific group or split your iWork/Office suite from other stuff. IMHO the spaces could be a little bit less wide. Ah and if you want more than one space, just re-run the mentioned command and kill the dock again. BTW. that’s the command: defaults write com.apple.dock persistent-apps -array-add ‘{“tile

Deploying a Node.JS web application with Express and nDistro

Duplicating a bucket on Amazon S3 with Ruby

Due to my studies I’m currently working with the Amazon Services Elastic Compute Cloud (EC2) and the Simple Storage Service (S3).

At first I tried the script on my local machine but stopped that due to my slow internet connection. Soooo I went over to EC2 and started an instance, configured it and tadaa,.., got every

Passing arguments/parameters using the node command

Run the following command: node foo.js myParameter In your script you can now access the attached parameters with: process.ARGV You will get: [ ‘node’ , ‘/path/to/foo.js’ ,’myParameter’ ] I needed something like that, to pass a boolean.

Render collections with layout in Rails

Today I found a very strange behavior of Ruby on Rails. I wanted to render a partial using the collection option. So far so normal.

Disabling error reporting of PHP on Snow Leopard

Due to my studies I’m currently working with Typo 3. I wanted to setup the CMS on my Snow Leopard based MacBook and ended in a bunch of warnings. Most of them informed about the use of deprecated function calls. First I just thought: Well that’s not my business!

To disable the so-called error_reporting do the following: sudo cp /etc/php.ini.default
