Lately I was searching for mobile notebook that I could use for remote work. I checked f ThinkPad series but they were huge bricks that have nothing in common with ‘mobile’ word. Then I saw ASUS Zenbook that I didn’t take into account before and it was exactly what I was searching for. Configuration of Skylake based notebook right now is not straightforward - there are still glitches and small bugs that are waiting to be fixed. I want to sum up what I’ve done after installation. I started with fresh Ubuntu 16.04 to get Debian based distro with possibly latest kernel and patches. ...

I’ve played with Docker a little in it early days but didn’t stick for longer with it. It’s stable now so I wanted to check how it’s running now. I really can’t accept this method of installation: curl -fsSL https://get.docker.com/ | sh I think that world is going to it’s end when I see such scritps… I prefer to do this manually, knowing exactly what I have to do.

I wanted/needed some statistics on few my machines. I saw earlier grafana and was impressed so this was starting point. Then I started reading about graphite, carbon and whisper, and then… I found InfluxDB. Project is young but looks promising. Let’s start! On project page there is no info about repo but it’s available, configure it: curl -sL https://repos.influxdata.com/influxdb.key | apt-key add - echo "deb https://repos.influxdata.com/debian wheezy stable" > /etc/apt.sources.list.d/influxdb.conf for Ubuntu use url like (of course selecting your version): ...

I wanted/needed some statistics on few my machines. I saw earlier grafana and was impressed so this was starting point. Then I started reading about graphite, carbon and whisper, and then… I found InfluxDB. Project is young but looks promising1. Installation of collectd is easy on Debian because packages are in default repo. One problem is that packages may be old, ex. on wheezy it version 5.1. But in backports/backports-sloppy2 you may find current 5.5, so enable backports first: ...
