mdpreview, a Markdown previewer to be used with an external editor

There are many Markdown previewers out there, from the simplest commandline tool + webbrowser to full-fledged Markdown IDE’s. I’ve tried quite a few, and I like none of them. I write my Markdown in an external editor (Vim), something very few Markdown previewers take in account. The ones that do are buggy. So I wrote mdpreview, […]

Manually scrolling a Python GTK Webview

I was trying to manually scroll a (Python) GTK embedded Webview in order to position the webview back to where it was after setting new contents with webview.load_html_string(html, ‘file:///’). I couldn’t get it to work, and Google wasn’t of much help either. I could scroll the Webview just fine from a key-press-event handler on the main window […]

Multithreaded dev web server for the Python Bottle web framework

I’m writing a simple web application in the Bottle framework. I ran into an issue where I had a single long-running request, but needed to make some additional requests from the browser to the server.

Batch create new users on Linux

A while ago I had to create many new users on a Linux machine. Since I’m lazy, I opted to automate this process. The newusers command combined with pwgen (to generate new passwords) was the solution. First I installed pwgen, a utility to automatically generate passwords: $ sudo apt-get install pwgen I created a file […]

A new Material design for Ansible-cmdb v1.5

Ansible-cmdb takes the output of Ansible’s setup module and converts it into a static HTML overview page containing system configuration information. While the previous generated overview page was functional, it didn’t look very good. So for the v1.5 release (which is now available), I gave it an overhaul. I decided on Material design because it gives […]
