OpenWRT on TP-Link TL-WDR4900
My wifi connections at home have been really slow using a really old AVM Fritz!Box, so I decided to upgrade to a TL-WDR4900. (The only thing still missing is 802.11 ac but the cheapest router providing that would be the Asus RT-AC66U AC1750 for twice the price of the TL-WDR4900, so that wasn’t worth it for me.) […]

Groupware options for small companies or organizations
(tbd – work in progress… Advice welcome…) Over the last weeks and months I’ve had multiple people asking for advice about groupware software. For me that is still kind of an open issue and I’m not sure what the best answer would be. These are the options I know and would consider using at this […]

After doing so, you can continue to install redmine as described in http://www.redmine.org/projects/redmine/wiki/RedmineInstall This will fail if the environment is not set correctly – this helped me a lot: http://stackoverflow.com/questions/12127603/usr-bin-env-ruby-noexec-wrapper-fails-with-no-file-or-directory […]

Typesafe viewmodel for MVC frameworks
Ever since I was working with MVC projects, looking at sample code even from Microsoft, I always wondered why everyone is using ViewBag and other “unsafe” techniques for the data to be displayed. I would have sticked to developing PHP applications if I wanted to do that. (And maybe even some PHP frameworks might do […]

Bézier curves
Some time ago I did some interview question that I just wanted to share mostly because I want to keep a backup of it. The questions were the following: We start with three dots (green) on the screen.

play! framework and Google App Engine
I just uploaded my first app to the Google App Engine – which is unbelievably simple with play! framework and the gae module. The application for my test is just 10 lines of code in the controller and all it does (for now) is to extract the URL of the latest Chromium Build from the […]

Synchronize a long-running task to the UI-Thread in WPF/.NET
This post explains how to process data from a task in WPF in a way I’d consider “best-practice”. The main code could or should be in the view-model. Code-behind (keep it short or better yet use a delegate command) And the code in the view-model: StartSearch() is a method in the view-model class and sets […]

Howto: Task and issues tracking with Redmine and Eclipse Mylyn
While working on one of my current projects I came to realize the importance of good task management and issue tracking. Sadly the use of an expensive Team Foundation Server does not guarantee good task tracking when the tasks are only used to do the rough planning in MS Project. Much more important than the […]
