Installed this interesting application on my laptop and a few other machines. It is called f.flux and it is an app that reduces the blue light in monitors in the evening. This is to prevent the stimulation that the blue light causes which ultimately effects your sleep.
So far I can say that in the evening with the new setup which has a soft orange-ish light is soothing.
The app has a very clever feature. You tell it when you typically wake up and then while you are working late it gently reminds you that you are waking up in 7 hours or some such number. A nice reminder not to over do it.
