To create problemz for solutionz
I recently bought a GTX 750Ti which isn’t supported by Ubuntu’s drivers yet. So I installed the drivers from Nvidia itself. They work great, the card is very quiet and operates without getting hot at all. One problem: after running an Ubuntu update that updates your kernel it won’t work anymore. sudo su cd /usr/src […]
I had to tweak some stuff to get a running Weasyprint on one of our Ubuntu servers; just following the install instructions from the docs didn’t work: sudo apt-get install python-dev python-pip python-lxml libcairo2 libpango1.0-0 libgdk-pixbuf2.0-0 libffi-dev shared-mime-info apt-get install libxml2 libxml2-dev apt-get install libxslt libxslt-dev pip install WeasyPrint pip install html5lib –upgrade Make sure […]
What is Odoo? Recently OpenERP is re-branded to Odoo. OpenERP was primarily an Open Source Enterprise Resource (ERP) software suite of business applications that includes Sales Management, Manufacturing, Purchase Management, E-commerce, POS, Accounting & Finance, CRM, and Project Management, to name just a few. However, having recently released a range of new and diverse applications, […]

I’ve been using Google Chrome as my primary browser for the last few years. Sorry, Firefox, but with all the stuff I need to work installed, it’s to slow and almost unusable. Let’s say you have a server with a self-signed HTTP SSL certificate. Every time you hit a page, you get a nasty error […]
I took me a while to find out that it’s not very easy to find out how big a sqlite table is on disk. But luckily the sqlite creators have a simple tool for that. It’s called sqlite3_analyzer and is available in precompiled format for Linux, Windows and OSX on SQLite’s Download section Confusing: There […]
To automate browser style testing in Ruby you can use Qt webkit caompatible browser with CapyBara. When you try to install it you’ll get this error when qmake isn’t found: An error occurred while installing capybara-webkit (1.1.0), and Bundler cannot continue. Make sure that `gem install capybara-webkit -v ‘1.1.0’` succeeds before bundling. To solve this […]

I recently started to do some development on some Rails4.0 based apps. Setting up a nice and clean Rails environment can be a hassle. The OSX/Windows instructions form railsinstalelr.org install an old version and are not working with Maverick, other instruction install macports; which I don’t like at all. So for OSX I followed the […]
Installing Ruby on Rails on Ubuntu is quite easy, but the Ubuntu packages install an outdated Ruby. The following instruction will probably work on older Ubuntu versions also, I just used the 14.04 test release to get a preview on the next LTS version of Ubuntu. This is just a quick install without RVM. If […]
