Ingress in Odense, Denmark

Ingress is an augmented reality game where you actually have to get off the couch and walk around your city to capture portals. The game is developed by Google and of course they’ll grab all your data, where you are and so on and so forth, moving on: it’s really fun. It’s plainly a social, geolocation based team game to dominate points of interest. Continue reading “Ingress in Odense, Denmark”

Building the greatest educational groupware

On one hand I would really like to file a lawsuit against creators and supporters of groupware like fronter, because I find myself damaged. Damaged by bad UX, bad integration and proprietary, not transparent restrictions.

On the other hand, I’d just like to create something awesome, that renders all this obsolete and even build a company around it. Continue reading “Building the greatest educational groupware”

Poet – displaying an author link

I’m still fiddling around with poet, the node.js blog generator and it’s really easy to add additional meta information like an author link for collaboratively driven sites.

Assuming you want to power a site with poet as a multi-user blog, you can easily attach the meta information in the individual MarkDown files:

    "title" : "Amazing Tutorial",
    "tags"  : [ "JavaScript" ],
    "category" : "Sanity",
    "date" : "2013-07-20",
    "author" : { "nick" : "Jonathan", "url" : ""} // additional line

After that, these informations will directly be available inside your templates when you render the posts. Assuming the views from the example repository, these are changes you could make to your template files:


extends layout

block content
				= post.title #{}.#{}.#{}
		- if (typeof( != 'undefined')
				p  by 
					a(href="#{}") #{}
			!= post.content
			- each tag in post.tags
					span.label.label-info #{tag}


			= post.title #{}.#{}.#{}
	- if (typeof( != 'undefined')
			p  by 
				a(href="#{}") #{}
		!= post.preview
		- if (typeof(post.tags) != 'undefined')
			- each tag in post.tags
					span.label.label-info #{tag}

With this method, you can add all kinds of meta information, that you might like with your posts 🙂

Poet – a node.js blogging platform

Poet is a great little node.js based project that allows you to start a blog in no time.

TLDR; Put a bunch of MarkDown files in a folder and it’s available as a blog to the rest of the world. I just started a new project for JavaScript and I of course wanted to run it on JavaScript, even before GHOST was released, so I went with Poet.

The description of the project by the author made me smile, so I’ll just quickly share this quote: Continue reading “Poet – a node.js blogging platform”

Feedly now allows OPML export for your feeds!

For a moment there I was really worried that feedly would go for a walled garden principle and keep all my feeds locked up, but they announced on their blog, two weeks ago already, that now you can export your feeds as OPML! Yay feedly!

All you have to do is to go to the following address while being logged in to feedly:

Now I can finally try out Stringer, a self hosted RSS reader!

Retext – Split View MarkDown Editor on Linux

Retext is a great MarkDown editor for beginners and is widely available on the Linux platform.

After introducing Uberwriter I thought it would be time to introduce Retext, which focuses on different features.


Retext features that are most valuable to me are the display of files in split view and PDF export. It’s a solid editor for both MarkDown and plain text files and I think it’s great for beginners to check the MarkDown syntax right away.

Having said that, it’s much like Mou, my favourite MarkDown editor on Mac OS X, but not as feature rich.

Features I’d love to see in Retext

  • custom CSS for PDF export
  • theming support for the editor itself
  • changing the “copy HTML” functionality so it only exports the body, without surrounding <body> and <html> tags

Installing Retext

Retext is available in most package managers, called retext, so for Debian / Ubuntu you would run:

    sudo apt-get install retext

On Arch Linux you currently have to remember to install python-markdown with it, since it is not automatically required as a dependency:

    sudo yaourt -S markdown-python retext

Raspberry PI (2), installing Arch Linux on USB drive

Update: Works with the Raspberry PI 2

This guide is not going to differ a lot from the one I posted a while ago: Boot Raspberry PI from a USB stick, but in particular the parts of editing the cmdline.txt and growing the partition are a little different when you want to install Arch Linux ARM on your Raspberry PI.

Private Github Enterprise Alternatives

Github Enterprise is basically a local installation of the famous service at github for your company or organisation. Although it comes with a quite a pricetag. In this post I want to show some alternatives that allow you to run a git server on your private network or on any server on the web. Continue reading “Private Github Enterprise Alternatives”
