Fix the brightness function keys on Ubuntu

Ubuntu brightness

If you’re running Ubuntu with discrete graphics on a Thinkpad T530, it’s most likely that the brightness function keys don’t work.
This happens when you’re using the proprietary Nvidia driver.

Luckily, this is easy to fix by adding one line to the /etc/X11/xorg.conf configuration.


Device Presence

Device Presence is a new project of mine that scans a network and shows you which devices are online. This information is stored in a database and plotted on a timeline.

Started using Flickr again

The 356 project I started has bleed to dead. Taking a picture everyday is doable, but not if you want it to be perfect.

I do want a place on the internet to share my photo’s so I dusted my old Flickr account and added the pictures I took for and some new one. From now on this will be the place to find my photo’s.

Qstarz BT-Q1000XT

A while ago I was searching for a GPS-logger to tag my photo’s with geolocation-data. Because I only use Ubuntu on my laptop the GPS-logger needed to be compatible with Linux. After doing some research I decided to buy the Qstarz BT-Q1000XT.



Recently I bought a D-Link DCS-5222L wireless pan-tilt network camera.
It’s a great webcam with good surveillance capabilities and night-view. But it has one downside; the web interface sucks. It works great with Internet Explorer in Windows, it even works with Firefox and Chrome in Windows. But when using Linux or using your mobile browser, you can’t see the live view.

I’m a developer, so I did some “reverse engineering” with Charles Web Debugging Proxy to see If I can make my own web interface. It turned out the be not that hard. On my GitHub you’ll find a PHP app that gives the following features:

  • MJPEG live-view
  • Controls for up/down/left/right
  • Controls for going to a configured preset
  • List of the available RTSP feeds

It may work with other D-Link camera’s but I haven’t tested that. Let me know if it does!

Bought a Raspberry Pi!

I just ordered a Raspberry Pi! It’s shipped in 11 weeks, so I have 11 weeks to find out what purpose I should give it. That should be enough.
